Alfred Wegener noted that fossils from a particular type of reptile are found on both sides of the Atlantic ocean. Which of the following would be the best explanation of how this occurred?
Answer:
B. The Atlantic Ocean did not exist in earlier times.
Explanation:
It simply didn't yet exist; there was only Pangaea surrounded by a global ocean. Before the Atlantic Ocean could open Pangaea had to be split. ... Deep beneath the Atlantic's waves it erupts as lava, providing new crustal material as it slowly pushes the continental plates apart.
What body structure did the second scientist use to determine that the first scientist had misidentified the fossil?
i heard it had to do something with DNA in the bones all animals that where fossalized where identafied by using the DNA in their bones
hope that helped

What do you mean by fossils?Fossils are the preserved remains of plants and animals whose bodies were buried in sediments, such as sand and mud, under ancient seas, lakes and rivers. Fossils also include any preserved trace of life that is typically more than 10 000 years old.
There are four main types of fossils, all formed in a different way, which are conducive to preserving different types of organisms. These are mold fossils, cast fossils, trace fossils and true form fossils.
Fossils are the remains or traces of ancient life that have been preserved by natural processes. Examples of fossil include shells, bones, stone imprints of animals or microbes, exoskeletons, objects preserved in amber.

Explanation:
The rescue workers can get energy to the batteries in their equipment during rescue missions by using a generator to convert the kinetic energy to potential energy. ... The best way is to use a hand crank such as a hand cranked flashlight or radio because it is easy to power enough energy for a short amount of time.

tudy the arrow that is circled in the image.
The sun is in the sky. Clouds with blue arrows pointing down toward water. A circled arrow is pointing from the water inland. Red arrows are pointing up from the land to the sky.
What happens at this point?
Warm air is rising.
Cool air is sinking.
There is a difference in air pressure.
Cool air is less dense than warm air.
Dont answer with anything including arrow'S There is no S read it before answering
Answer:
The blue arrows in circles indicate that cool air is sinking
Explanation:
Warm air is less dense than cool air. For this reason, warm air rises, creating a low pressure region, and cool air, which is more dense than warm air, sinks creating a high pressure zone. In this description, the red arrows represent the hot air rising up to the sky, and the blue arrows represent the cool air sinking down. The reason warm air is less dense is because its molecules are further apart than when it is cold, making it lighter per cubed square foot.
So, we can conclude that option a) Warm air is rising is incorrect, because the warm air rising is represented by the red arrows pointing up form the land to the sky.
Options c) Cool air is less dense and d) warm air is more dense are also incorrect, because as mentioned before, cool air is more dense than warm air.

How does the structure of a root hair cell support its function? Explain your answer and I will give brainliest.
Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria, which release energy from glucose during respiration to provide the energy needed for active transport.
What are Root hair cells?Plants do not have a heart, blood, or circulation system, but they do need a transport system to move food, water, and minerals around.
They use two different systems - xylem moves water and mineral ions from the roots to the leaves - phloem moves food substances such as sucrose (sugar) and amino acids from the leaves to the rest of the plant. This movement of food is called translocation. Both of these systems contain cells that make continuous tubes running the full length of the plant from the roots, up the stem, and through the leaves. They are like blood vessels for the plant.
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria, which release energy from glucose during respiration to provide the energy needed for active transport.

Consider the parts of a polar ecosystem and a desert ecosystem.
– Identify one abiotic factor present in each type of ecosystem.
– Identify one biotic factor present in each type of ecosystem.
– Explain why both the abiotic and biotic factors are different in each ecosystem. Use examples from each ecosystem in your explanation.
(NO LINKS PLEASE) (77 POINTS)
Answer:
One biotic factor includes soil, air(oxygen and carbon dioxide), water.
One biotic factor includes animals and plants.
Both factors are different in each ecosystem. This is because, for example, the soil in desert ecosystem can differ from the polar ecosystem. Animals in polar ecosystems include polar bears, wolves, etc. while desert ecosystems have animals like deer, artic fox, etc.

1 connection between mutations and reproduction
Answer:
An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur.

What exactly is an unbalanced force? How is that different from a balanced force and how things move? Give an example of an unbalanced force and a balanced force
Answer:
When one force is greater than another, the forces are not balanced, they are unbalanced. By applying an unbalanced force, you can change the motion of an object. Unbalanced forces can make an object at rest start moving, make a moving object stop, or change the direction and speed of the object.
