The biggest obstacle to traveling by boat on the Congo River is A. the many cataracts
The numerous cascades on the Congo River are the main challenge for boat passage. Navigation on the Congo River is challenging and dangerous due to a number of strong cataracts, or rapids and waterfalls. The hills and troughs in the riverbed that force the water to flow quickly across them are what generate these waterfalls.
On the Congo River, there are a total of seven major cataracts that make navigation extremely difficult and demand that boats be unloaded and portaged around. There are also shallow places brought on by the drought. Because of the ideal growing conditions provided by these shallow locations, the water plants flourished, producing troublesome obstructions for the boat.

Answer:
The diet is the most likely cultural aspect that will be affected by this region's vegetation.
Explanation:
The region that is described is obviously a rural region, where agriculture dominates. As said, the soil is very fertile but only suitable for few plants to be grown and at a high quality. While the people living here will naturally be slightly more isolated and have their own unique cultural traits, the most affected by agriculture will be their diet.
Since people are able to produce high quality and high quantity of only a few plants, it is easy to assume that those few plants will be dominant in their diet. Living in a rural environment will also mean that the available agricultural products from other places will not be in a very high number, so the people will use their own products. This will result in the development of numerous specialties based on the few dominant plants, creating a unique cuisine in the region.
Answer:
The right answer for Plato is Climate
Explanation:
What are two different ways you could find the value of a? Explain these methods.
A right triangle is shown. An altitude is drawn from the right angle to the opposite side to form 2 line segments with lengths 9 and 16. The length of the other 2 sides are 15 and a.
Answer:
Sample Response: You could use the Pythagorean theorem, since you know the length of the hypotenuse is 9 + 16 = 25 units and the length of one leg is 15 units. To find the value of a, use the relationship that the the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. You could also use the geometric mean (leg) theorem, which states that the length of the hypotenuse is to the length of an adjacent leg as that adjacent leg length is to the length of its corresponding segment in the hypotenuse. So you could write and solve the proportion 25/a = a/6.
Explanation:
I just did it
From the triangle given, the ways to find a will be the use of a Pythagorean theorem and a geometric mean.
By using the Pythagorean theorem, one will have to add the square of the legs and find the square root. Since the hypotenuse is 9 + 16 = 25 units and the length of one leg is 15 units. Then, in order to find the value of a, one will have to use the Pythagoras theorem.
Also, one can use the geometric mean theorem. Therefore, the values given will be rewritten as 5/a = a/6. Then, the person can solve the equation.

How would human activities affect the migration of animals like the Christmas crabs in Australia?
Answer:
Most of Christmas Island's adult red crabs begin their breeding migration to the sea as soon as the wet season rains have established. But we can never be sure when the wet season is going to begin!
The crabs' breeding timetable is fixed around the phases of the moon. Spawning (the dropping of their eggs into the sea) must occur before sunrise on spring tides during the last quarter of the moon, regardless of any other factor. The timing of spawning is the only certain and predictable part of the whole migration; all other stages of the migration will vary with the prevailing weather.
The crabs will start their migration if there is enough time for them to complete their downward migration, mate and develop eggs before the next suitable spawning date.
The red crab breeding migration comprises a series of separate actions on the crabs' part that follow on from one to the other in a programmed sequence. These separate actions in combination make up the breeding migration and one action will not occur unless the preceding action is accomplished. If there isn't enough time for them to be able to do all of these things before the next spawning opportunity, they will delay the start of their migration and attempt to meet the following month's spawning date.
The first action that occurs is movement of crabs to the sea. The largest mass movement of crabs takes place in this first downward migration. Males farthest inland start this movement and are progressively joined by more and more crabs (both males and females) as the movement progresses toward the sea.
When the crabs arrive at the shoreline, they dip in the sea to replenish body moisture and salts. The male and female crabs then move back on to the shore terraces where the males dig burrows for mating. Mating takes place and then the males again dip in the sea and then they will start their return migration.
The females remain behind in the mating burrows to brood their eggs. This takes a couple of weeks. A day or two before the spawning date the females emerge from the breeding burrows with ripened eggs and move to the shoreline where they again dip in the sea and then retreat to shade.
Before the turn of the high tide and just before dawn the females will again move to the waterline and around the turn of the tide they will drop their eggs into the sea. After they have jettisoned their eggs the females commence their return migration.
The next phase of the breeding migration takes place in the sea. The eggs that the females drop into the sea hatch immediately into larvae. They grow through several larval stages into tiny prawn-like animals called megalops. After about four weeks the megalops emerge from the sea and they moult into baby crabs. The baby crabs then move inland and settle at suitable localities. The successful emergence of baby crabs is unpredictable but is incredible when large numbers emerge. Some years very few, or none, emerge. After about four years growth crabs will take part in the breeding migrations and the life cycle continues.
If the rains stop or peter out, the crabs will delay the start of their migration, or, if they have started migrating, they will stop moving and stay wherever they are until the rains begin again. It is rare that substantial rains will begin early enough in the year for a spawn during the last lunar quarter in October - but it has happened! Spawning in November or December are the more usual, which means that rain must commence in the preceding month and continue.
All phases of the crabs' breeding migration involve colossal numbers of crabs and usually occur all over the island. If the rains continue, there is usually a second, and sometimes even a third, smaller, downward migration by crabs that did not join in the first migration. When this happens it is possible to see crabs on return journeys mingling with the crabs on their downward migration. It can become confusing for all concerned! We are sorry that we can not be more explicit about the timing of the start of the red crab migrations, but the weather as you know cannot be accurately predicted. The best advice we can give is to be at Christmas Island during the last quarter of the moon in either November or December for the best chance of seeing something interesting happening in the annual red crab migration. If you are able to arrive earlier and to stay longer the more parts of the migration sequence you will be able to experience.

What is the thermocline?
beneath 200 meters, ocean water cools at a constant rate of 1°C per 100 meters depth
the ocean area near the polar regions where water temperatures cool
where magma is forced up through the ocean floor along mid-ocean ridges
the area off the continental shelf that declines to the ocean floor
Answer:
Beneath 200 meters, ocean waters cools at a constant rate of 1°C per 100 meters depth.
Explanation:
The ocean water is with the same characteristics throughout all of the oceans. The differences come in differences in temperature, density, salinity, etc. When it comes to temperature, it is what influences the other characteristics, and it is what causes the movement of water in the oceans.
The movement of ocean water occurs because in some parts, the ocean water gets cold, while in others it gets warm. The cold water drops deeper and moves toward the less dense warmer water, and as it gradually warms up itself it rises, pushing the warm water in opposite direction. The water is mixing at the surface, but this is not the case below 200 meters of depth, where water mixing stops. This zone, where the water is not mixing, is known as the thermocline and exists as such throughout all of the oceans.

Why did Montenegro initially sign the Carrington Plan and then later change their vote?
Answer and explanation:
The President of the Presidency of the Republic of Montenegro, Momir Bulatović, with the previously obtained consent and authority of the Parliament of the Republic of Montenegro to do so, accepted Carrington's peace plan, and the presidents of all member republics rejected that plan.
Under various, numerous and serious threats and coercion by Slobodan Milosevic and exponents of his regime, generals, loyal politicians, and media pressure, harassment and satanization of Momir Bulatovic's case in The Hague on October 18, 1991, Bulatovic's signature was soon withdrawn from the Hague Document.

This pie chart shows statistics related to the world's population. Which statements does the pie chart support? Check all that apply. More people live in Latin America and the Caribbean than in Africa. More people live in Asia than the rest of the world combined. Oceania has the smallest population of all the continents. The population of North America is relatively low. Africa has a smaller population than Europe does.
Answer:
More people live in Asia than the rest of the world combined. Oceania has the smallest population of all the continents. The population of North America is relatively low.Explanation:
According to the Pie chart, 60.5% of the world lives in Asia which is above 50%. This means that the rest of the world is smaller in terms of population than Asia.
Oceania from the chart has 0.5% of the world's population which puts them at last on the population scale of continents.
North America has the second largest population at 5.2% which means that they have a low population in relation to other continents.
What is the thermocline?
beneath 200 meters, ocean water cools at a constant rate of 1°C per 100 meters depth
the ocean area near the polar regions where water temperatures cool
where magma is forced up through the ocean floor along mid-ocean ridges
the area off the continental shelf that declines to the ocean floor
Answer:
Beneath 200 meters, ocean water cools at a constant rate of 1°C per 100 meters depth.
Explanation:
The thermocline is one of the three ocean zones when it comes to separating the ocean waters by temperature and weather waters mix or not. The top layer of water, or the surface water, is called the epilimnion. The second layer, or thermocline, is called metalimnion at starts from 200 meters of depth. And the last one, or deep ocean, is the hypolimnion, starting from 1,000 meters of depth.
The surface layer is the one where the water is the warmest and it mixes. In the second layer, we have the thermocline, where the water is not mixing anymore and it sharply drops in temperature. The water temperature generally drops by 1 degree Celsius per 100 meters of depth. The third layer is the coldest, but there aren't big changes in temperatures between the starting and endpoint of it.

1.)What is the difference between the different types of star clusters?
2.) Summarize the characteristics of a dwarf galaxy.
3.)Name at least three properties of stars revealed by special characteristics:
4.) How do scientists know dark energy exists?
5.)What observations and reasoning led to the development of Hubble's Law?
6.) What was the foundation of Georges Lema^itre's Big Bang Theory?
Answer:
Not too sure on 3,5, and 6, but here's the other three.
1. The three types of star clusters differ in size and location. Globular clusters are the largest, and are located in a halo around a galaxy. Open clusters are the second largest, only containing hundreds of stars rather than the hundreds of thousands in globular clusters. They're found in the plane of the galaxy. The smallest are associations, which contain extremely young stars and can be found in gas and dust regions of the galaxy.
2. Dwarf galaxies lack evidence of recent star formation, contain little to no gas, and are elliptical.
4. We can't observe dark energy, however, we can observe its effect on other observable things. For instance, there is a galaxy that when we observe it, we see it five times. As in, it appears that we are seeing five different galaxies, but it's just the one. This happens because the light being produced from the galaxy is warped by immense gravity.

Write a general statement that could be used to determine if other mass extinctions have occurred in Earth’s history. Explain why your statement would is appropriate. 2-3 Sentences.
Answer:
Explanation:
The most appropriate example is the extinction of the dinosaurs. All sorts of theories were put forth. Most think there was a dramatic change in the environment, a change that left no time for the dinosaurs to adapt to that change.
Whatever happened, an asteroid, volcanic eruptions, or something else, whatever you propose has to explain why birds and mammals survived.
So whatever occurred, it had to be dangerous to land animals, but not those who flew or those who could think well enough to avoid whatever was happening around them.
That said, I would propose that it was a virus that was not air born and the genetic make up of mammals could avoid the harmful effects of the virus.
I would propose that this is the only explanation that works. Perhaps the makeup of the blood could not adapt to the extinction. The blood of a dinosaur might not have included very powerful neutrophils (which fight disease).
