Answer:Artificial selection is the process by which humans choose individual organisms with certain phenotypic trait values for breeding. If there is additive genetic variance for the selected trait, it will respond to the selection, that is, the trait will evolve. evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. Evolution can an animal to make it almost unrecognisable, like cephalopods and how they evolved to make them more buoyant

Write a summary of the pathways rocks can take to become sedimentary, igneous, and metamorphic rocks.
Answer:
When a certain type of rock, specifically, an igneous rock, is deeper into the ground, and it is under the influence of high temperatures and pressures, it will start to change its molecular structure over time. In addition to the high temperature and pressure, chemical influences are also very important, so the the rock will gradually turn into a metamorphic rock.
Depending on the type of influences, and their intensity as well, one type of rock can evolve into multiple different types of metamorphic rocks.
Some structures, like the leg bones in the modern day whale, no longer have a useful
function but it is believed that once upon a time they did have a specific function. These

The changing of the rivers created more ____________ for animals
aRegeneration
bVegetation
c Erosion
d Habitats
Answer:
D) Habitats for animals.
Explanation:
It depends what the question means when it says 'the changing of the rivers'. I took it as the rivers are changing size and becoming more spread out. In that case, I chose habitats.
The more water there is, the more habitat there is for sea life.
All in all, the correct answer is D).

Make a Punnett Square for a cross between a homozygous dominant and a hybrid pea plant. Use C for dominant traits and c for recessive traits. Place the homozygous pea plant across the top.
Okay so i need more information, but the top should be both dominant (C C), while the side is one dominant, one recessive (C c). So the bottom two squares of the punnett square, are both one dominant, one recessive (C c) and the top two are both dominant (C C) Not entirely sure what you're asking.

What feature is the same in the formation of many sedimentary rocks and fossil fuel?many sedimentary rocks and fossil fuels-
A-require material to be buried and exposed to heat amd pressure.
B-are made out of organic material that stores the sun energy
C-form where there are frequent earthquakes and volcanic activity
D- are produced high in the mountains where temperatures are low
Answer:
maybe C i'm so sorry if this is wrong
Explanation:
Organic materials and silt build on top to produce fossil fuels. Heat and pressure transform organic materials into coal, petroleum, or natural gas. Therefore, option (A) is correct.
What are fossil fuels?An extracted and burnt fossil fuel is a hydrocarbon-containing substance that naturally originated in the Earth's crust from the remnants of extinct plants and animals. Coal, oil, and natural gas are the three primary fossil fuels.
Because certain sedimentary rocks contain trapped fossil fuels, sedimentary rocks and fossil fuels are connected. As organic materials and silt build up on top over time, fossil fuels are created. The organic material undergoes a chemical shift under heat and pressure, turning it into coal, oil, or natural gas.

Answer:
The correct option is C: antigen-binding sites
Explanation:
The antibody is shaped much like the letter Y in the English alphabet. It has two antigen binding sites that are identical in nature. The specificity of these sites is determined by the amino acid sequence that makes it up. Antibodies are complementary to these antigen binding sites, and the antibodies have an incredible ability to recognize a great variety of antigens.

Jeremy decides to make a model of the Earth. He makes his model by drawing the Earth on a sheet of paper. When he finishes his model, Jeremy notices that the shapes and sizes of the continents are not correct. He also notices that the Earth's surface is cut off at the edges of the drawing. Jeremy decides that he wants his model to be more accurate. How can Jeremy improve his model so that it is more accurate? A. Use a ruler to draw the continents with straight lines. B. Use a thicker piece of paper. C. Draw the Earth on a sphere. D. Draw the Earth smaller on the paper.
Answer: C. Draw the Earth on a sphere.
Explanation:
Jeremy should draw the Earth like a small sphere that can be drawn completely on the paper and edges will not be left incomplete. The shape and size of the continent can be traced using a map or a stencil. The exact dimension to be drawn is not important but the boundaries should be taken care of and must be accurate.
Answer:
C. Draw the Earth on a sphere.

Answer:
share a common ancestor
Explanation:
The similarity in their embryos and embryonic development suggests that reptiles, birds, and mammals share the same ancestor.
Similarity in the structure and development of embryo is one of the evidences that is been used by scientists to support the theory of evolution of species. According to the theory of organic evolution, all organisms are on earth as a result of descent with modifications from common ancestors.
Reptiles, birds, and mammals are all vertebrates. They share some basic characteristics and are thought to have shared a common ancestor before each group took different adaptive channels leading to their differences as they currently exist.
