1 connection between mutations and reproduction

Answers

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.

Explanation:

mutations affect reproduction. if the mutation has a deleterious affect on the phenotype of the offspring the mutation is a “genetic disorder”

DNA in the bones used to determine that the first scientist had misidentified the fossil.

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.

*Note that in the images below changes in eccentricity are exaggerated so the effect can be seen in the images. Earth's orbit shape varies between 0.0034 (almost a perfect circle) to 0.058 (slightly elliptical).*

a. A change in the eccentricity of Earth's orbit towards its maximum will increase or decrease the solar input that the Earth receives?

b. Explain how an increase in the eccentricity of the Earth’s orbit will alter the climate.

Answers

Answer:

I'm not sure about question b, but I'm pretty sure a is increase

Explanation:

I think I remember learning about this

Eccentricity in the orbit of the planet is the measurement of the deviation of the planet from its circular path. The maximum eccentricity of Earth's orbit increases the solar input and will alter the climate.

What is the effect and relationship of the eccentricity and climate?

The eccentricity is the change or the modification of the elliptical orbit shape of the planet where it revolves around the sun. When there is the maximum eccentricity of the orbit then the solar input or the heat the planet receives will increase.

The solar heat or the input will increase due to the maximum eccentricity as the distance of the planet and the sun have changed and they have become more close, because of that the heat and solar energy will be more in contact with the planet's surface.

The increase in the eccentricity of the Earth’s orbit will affect the climatic conditions as the orbital distance has become close to the sun and the revolution has been affected and the climate is controlled and regulated by the heat emitted from the sun.

Therefore, an increase in the eccentricity of the Earth’s orbit will affect the climate and also increase the solar input.

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

Answers

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.

Cool air is sinking is what that represents

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?

Answers

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.

Really none because Alfred Wegener came up with the theory Pangea . Where all the continents were together in one . Some of his proof was that the fossils where on both sides so they couldn’t of swam and there was no other explanation and the continents fit together like a puzzle . So really none but if I were to pick on I would pick d .
