PLEASE ANSWER ASAP. Thank you. QUESTION: Explain the evidence that suggests that the universe is expanding.

Answers

Answer 1
One piece of evidence that proves that the universe is expanding is that there is a direct relationship between the speeds of distant galaxies and their distances from Earth. In fact, Hubble discovered that the farther away a galaxy is, the faster it is moving away from us. Although scientists today still don’t know the nature of this mysterious energy causing this acceleration, Hubble’s evidence has strengthened many theories about the large-scale structure of the universe.

Wind carries seeds to the area and plants grow from these seeds

New soil forms from rock

Answers

c because

The first plants to move into the new bare ground after a wildfire are wildflowers or “weeds.” These fast-germinating, leafy herbaceous plants are also known as “forbs” or “ephemerals.” They quickly germinate, grow and produce a new crop of seeds.

Answer:

Pioneer species are established

Explanation:

A forest fire would represent the process of secondary succession.

In secondary succession, the first stage is the growth of pioneer species. The soil still remains, so no new soil needs to be made.

This rich soil allows for pioneer species to grow in the forest.

Energy can be measured in calories, 1,000 calories is called a kilocalorie (kcal),
If the producers have 10,000 kcal of energy and 10% is transferred to the primary
consumers, how much energy is transferred?

100 kcal
1,000 kcal
10 kcal
Plz help me which one is it!!!!!

Answers

Answer: 1,000kcal

10% of 10,000 is 1,000.

The amount of energy transferred if 10% is transferred to the primary  consumers is 1000kcal

Given the following parameters

Amount of kcal the producer have = 10,000kCal

Percentage transferred to the primary consumers = 10% of the amount produced

Get the amount of energy transferred;

[tex]Energy \ transferred = \frac{10}{100} \times 10,000\\ Energy \ transferred =0.1 \times 10,000\\Energy \ transferred =\frac{10,000}{10}\\Energy \ transferred =1000kcal[/tex]

Hence the amount of energy transferred if 10% is transferred to the primary consumers is 1000kcal.

A city is supplied by water from local wells. The city discharges its treated wastewater into the ocean.The city uses 25,000 liters of water per person per year. Precipitation falls in the amount of 25,000 liters per person per year.



Is the city using its water supply in a sustainable manner?

A)yes
B)no

Answers

Answer:

B)no

Explanation:

Sustainable use of water means use of water to fulfil various human needs for water without having any negative impact on the environment.

The sustainable use of water allows a minimum of 20 to 50 litres of daily water per person to fulfil their water needs, that means 600 litres maximum per person per year but in the given situation the city uses 25,000 litres of water per person per year.

This shows that people in the city are not using water sustainably which is causing a fall in precipitation.

Hence, the correct answer is "No".

Explanation:

Humans are altering the carbon cycle by _____. (5 Points) killing off large numbers of animals, which reduces the amount of carbon in the system growing crops, which increases the amount of carbon in the system increasing their population, which reduces carbon dioxide from the atmosphere burning fossil fuels, which adds carbon dioxide to the atmosphere extracting fossil fuels from the ground, which removes carbon from the system

Answers

Answer:

By burning fossil fuels, which adds carbon dioxide in the atmosphere.

Explanation:

One of the buffers that contribute to pH stability in human blood is carbonic acid (H2CO3). Carbonic acid is a weak acid that, when placed in an aqueous solution, dissociates into a bicarbonate ion (HCO3-) and a hydrogen ion (H+).
Thus, H2CO3 = HCO3- + H+
If the pH of the blood increases, one would expect:

(A) a decrease in the concentration of HCO3- and an increase in the concentration of H+

(B) an increase in the concentration of H2CO3 and a decrease in the concentration of HCO3-

(C) a decrease in the concentration of H2CO3 and an increase in the concentration of HCO3-

(D) an increase in the concentration of HCO3- and a decrease in the concentration of OH-

(E) a decrease in the concentration of HCO3- and an increase in the concentration of both H2CO3 and H+.

I'm not sure if it is C or D ​

Answers

Answer:

The answer is "Option C".

Explanation:

In the given question, the pH scale is used to evaluate acid or basic (alkalinity) formulas. It is nearly positive throughout the blood. Human blood has to maintain its pH at about 7.4, to prevent dramatically increased or lower changes, even though the bloodstream enters or exits acidic or essential substances.  

The buffers are essential for stabilization management. Calcium carbonate produced as carbon dioxide joins the blood system and combines with the liquid is a buffer which adds to the pH level in the human blood. It is returned to the water and distributed as a waste product until it enters the lungs, that's why choice C is correct.

1. ATP will increase

2. NADPH will increase

3. Sugar will decrease

Explanation:

Had the same problem

The effect of temperature on these molecules are ;

ATP will increase NADPH will also increase  while Sugars will decrease

ATP (  Adenosine triphosphate ) is the molecule in cells which stores energy in cells while transferring the energy needed within cells as well. When the temperature of a cell is raised above the required temperature this molecule will also increase in response.

NADPH is an electron donor which is found in organisms, it also provides the reducing power for certain reactions in the organism ( anabolic ) and the gathering of NADPH oxidase. increases as the temperature of the organism increases.

Hence we can conclude that as temperature increases , ATP will increase , NADPH will increase while Sugars will decrease.

Answers

Answer:

Explanation:

In 1976, The Viking 1 and Viking 2 probes landed on Mars. For six years they transmitted fascinating panoramic views of the red and rocky soil of Mars back to Earth. Twenty years passed before a third probe landed on Mars. In 1997, the Pathfinder probe landed a miniature vehicle named Sojourner on the planet. The probes operated for three months and sent back large amounts of data on the Martian environment. At the same time, the Mars global surveyor probe was placed in orbit to take an overall portrait of the planet. It supplied hundreds of thousands of bits of information, especially on climatic variations.

Answer:

Viking 1 and Viking 2 probes transmitted panoramic views of the red and rocky soils back to Earth after six years later. The Pathfinder probe sent back large amounts of data of the environment especially about climatic variations in only three months. You can tell the technology was very different between these two because of how long it took for each probe to gather data.
