Each cell has a structure that separates the inside of the cell from.the environment. What cell is this?
Answer:
Either the cell wall or the cell membrane.
Explanation:
All cells have cell membranes which line the outside of the cell, and some cells have cell walls, which also line the outside of the cell. Since all cells have cell membranes I am inclined to believe that the correct answer would be cell membranes.
Describe the relationship between cell shape and function. Give an

If the object shown has a mass of 80g, what is the density?
Answer:
C. 1.23 g/ml
Explanation:
[tex] Density = \frac{Mass}{Volume} [/tex]
Mass of rock = 80g
Volume of rock = final fluid volume - initial fluid volume
Volume of rock = 265 cm³ - 200 cm³ = 65 cm³
[tex] Density = \frac{80g}{65 cm^3} [/tex]
[tex] Density = 1.23 g/cm^3 [/tex]
1 cm³ = 1 ml
Therefore, density of the object = 1.23 g/ml
Of the three waves shown, Wave 2 has the greatest
wave speed, because it has more crests than the other ropes
O frequency because it has a large wavelength than the other ropes
wave speed because the rope is moving up and down faster than the other ropes
frequency, because there are more crests in the same length of rope than there are in the other waves
Answer:
D. frequency, because there are more crests in the same length of rope than there are in the other waves
Explanation:
Wave frequency is defined as the number of waves passing a fixed point at a given time.
Wave frequency is highly influenced by the number of crests in the wave that pass the fixed point in 1 second. It means, more is the number of crests in the same length of rope, the higher will be the wave frequency.
Wave 2 has a maximum number of crests and thus wave 2 has the greatest wave frequency in comparison to other ropes.
Hence, the correct answer is "D".
Earth is 150 million kilometers from the sun, and the solar "wind" travels at about 400 km/sec. How long does it take particles from a solar storm to reach Earth? (Hint: Time = Distance / Speed. To convert from seconds to hours, divide the time in seconds by 3600.)
Answer:
The correct answer is - 4.34 days.
Explanation:
Given:
Distance from the sun to earth = 150 million kilometer
= 1500,00,000 km
The solar "wind" travels = 400 km/sec
= 400*60*60 km/ hour
= 1440000 km/hour
Then time = distance/speed
time = 1500,00,000 km/1440000 km/hour
time = 104.166666667 hours
time = 104.166666667/24
= 4.34 days.
A tactic used long ago by conquering nations on those they sought to control was to
invade the land and salt the fields. What were they hoping to accomplish by doing
this?
Answer:
I don't know this answer sorry dear
Explanation:
hope other wilp help you soon
The invading nations aimed to devastate the agricultural productivity and food supply of the local population.
Salting the fields was a deliberate act of agricultural sabotage with long-lasting consequences. The process involved spreading large amounts of salt over the farmland, which effectively rendered the soil infertile, inhibiting the growth of crops and making it nearly impossible to cultivate food. This strategy was particularly effective in ancient times when agriculture was the primary means of subsistence.
The devastation caused by salting the fields not only impacted the present generation but also affected future generations as the soil remained barren and required significant efforts to be reclaimed for agricultural use. This tactic was not only meant to suppress immediate resistance but also to instill fear and discourage other potential adversaries from rebelling against the invading nation.

Summarize the process of sexual reproduction and explain how variations of inherited traits can increase or decrease an organism’s chance of survival
Answer:
Explanation:
A Human cell has 46 chromosomes. (I’ll use humans to keep things simple). In sexual reproduction both humans have 23 chromosomes, in their sex cells. (Men have 23 in a sperm and women have 23 in an egg cell). These half cells merge to create 1 unique cell, that has characteristics of both male and female. The cells multiply and then a baby is born with a unique set of genes. These cause variations, and remember these variations can carry from generation to generation. As for how variations can increase a chance for survival, variations allow unique gene sets to be made, so that in case of a disease (in this case I’ll use a disease, but it could also include harsh environmental conditions), these unique gene sets may give an individual natural immunity to the disease. How can a variation decrease an organisms chance for survival? Well, s there are many ways that a unique gene set can make it difficult to survive. For example a genetic disease your family has had a history with. These diseases include, but are not limited to, cancer, diabetes, and schizophrenia.

Explain why you cannot draw a conclusion about the effect of one variable in an investigation when the other variables are NOT controlled.
Answer:
Because you don't know which variable caused the effect.
Explanation:
It's always important to have a control because you need to be able to pinpoint exactly what variable caused the specific effect to take place. This is also why multiple variables can not be tested at once.

PLZ HURRY
Answer:
The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end. The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications. The limit for long wavelengths is the size of the universe itself, while it is thought that the short wavelength limit is in the vicinity of the Planck length.[4] Gamma rays, X-rays, and high ultraviolet are classified as ionizing radiation as their photons have enough energy to ionize atoms, causing chemical reactions.
Explanation:
Answer:Each color has a different wavelength. Red has the longest wavelength, and violet has the shortest wavelength. When all the waves are seen together, they make white light. White light is actually made of all of the colors of the rainbow because it contains all wavelengths, and it is described as poly chromatic light.

Hundreds of years ago, a volcanic eruption killed many plants and animals on a tropical island. Today, the island looks much as it did before the eruption. Why is this true? Destroyed ecosystems always return to their exact original state. Altered ecosystems only regain stability from the development of grasses. Geographic barriers prevent the migration of animals to island habitats. Destroyed environments can recover through ecological succession.
Answer:
Destroyed environments can recover through ecological succession.
Explanation:
Ecological succession describes a progressive change in the species in an ecological community over time.
This can happen after some disturbance such as a fire, earthquake, or volcanic eruption. It can mean that a e can return to the state it was before the event.
A famous celebrity has an extreme security system for their estate. The security system includes sensors in the ground as well as on the sides of the buildings. A loud truck drives down the road entering the estate. There is a sensor in the ground and another on the side of the security guard’s shed. If both sensors are 100m from the truck, which sensor will pick up the noise of the truck first and why?
A.
Guard Shed - The sensor on the security guard’s shed will detect the sound first because the sound is traveling through the air and sound will travel fastest through a gas.
B.
Ground - The sensor in the ground will detect the sound first because the sound is traveling through the dirt and sound will travel fastest through a solid.
C.
Same time - Because the sound is traveling through both the ground and the air at the same time, it will reach both the shed and the ground sensor at the same time.
D.
Neither sensor - 100m is too far for the sound to travel. Neither sensor will pick up the sound of the truck until it is closer to them.
Answer:
B. Ground - The sensor in the ground will detect the sound first because the sound is traveling through the dirt and sound will travel fastest through a solid.
Explanation:
Sound wave is an example of mechanical wave, which means sound waves require a medium to travel through. However, how fast a sound travels is dependent on the kind of medium it travels through. Sound travels fastest via a SOLID medium, then liquid and slowest through gases.
According to this question, sensor in the ground and side of the security guard’s shed were placed in an estate owned by a famous celebrity. A loud truck, then, drives down the road entering the estate.
Based on the principles of sound eaves movement, the sound from the truck will be picked by the sensors in the GROUND first because the sound is traveling through the dirt and sound will travel fastest through a solid.
NASA has discovered a new planet in a distant solar system. On this new planet, they have found a mysterious green slime. The green slime only grows at certain temperatures and under certain moisture levels. Scientists found that if they put the green slime in a freezer, it would shrink itself to maintain an internal temperature of 75°. They also found that the green slime has specialized pumps to pump out water if it gets too wet. As of yet, none of the green slime samples have reproduced, but they do appear to be growing very slowly. When looking at the green slime under the microscope, scientists can see smaller structures filled with green slime and tiny pumps. What are some reasons the green slime may be considered a living organism? What are some reasons the green slime may not be considered a living organism? Do you think the green slime is alive? Why or why not? *
Answer: The following assumptions can be made for the green slime.
Explanation:
1. The green slime has many characteristics, which indicates that these are adaptations which were used by the slime to survive. It uses pump to expel out excess water, and in freezing it can shrink itself to maintain its temperature. Thus these characteristics indicates that the green slime is living.
2. The green slime did not reproduced. This indicates that the slime was not living.
3. The slime was living because it had characteristics which enable it to survive like other living organisms.

what determines how far south the cold air from the north pole travels
Answer:
Please mark as Brainliest.
Explanation:
Polar easterlies are the cold and dry wind that blows from the polar regions (North pole and South pole) to the region of 60 degrees latitude. This type of wind is formed due to the sinking of the cold air resulting in the formation of a high pressure zone at both the poles. This wind when blows from the poles to the 60 degrees latitude, it slightly gets deviated towards the western side because of the effect of the Coriolis force. This Coriolis force comes into the picture due to the earth's continuous rotation.
Thus, the polar easterlies determines how far south the cold air travels from the North Pole.
