Answer:
John Stephen Jones states that in evolution it is necessary to have into account three factors: natural selection, mutation, and random variation.
Explanation:
These three mechanisms influence evolution and they are responsible for generating phenotypic diversity that is observed in humans.
I recommend to read his article (chapter book):

Why do land plants need to conserve water
Answer: Some arid-climate plants are able to conserve water because of their reduced leaf size. Less leaf surface area results in reduced water loss through the epidermis. Small leaves have fewer stomata than larger leaves, and that adaptation also reduces water loss.

Explanation:
Select the living organisms that will decrease as a result of the loss of coral in the food web.
Answer:
Butterfly fish, Triggerfish, parrotfish, and sharks
Explanation: Because the first three fish listed feed on coral, their populations will decrease if coral is eliminated because that means there will be less food to go around for the populations to consume. Many will die out. If those fish die, there will be less of them for the sharks to eat, causing the shark population to decrease as well.

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.

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.

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.

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.

Si cruzamos dos individuos homocigotos de cobaya, uno negro y otro blanco, y sabemos que el carácter negro es dominante sobre el blanco. Su descendencia tendrá la siguiente características
Answer:
The offspring will be black because they are heterozygous for a dominant trait that is controlled by monogenic inheritance.
Explanation:
Guinea pigs will be heterozygous because they inherit a dominant allele that encodes for the black color and a recessive allele associated with the white color. Heterozygosity is a genetic condition associated with the presence of two alleles at a locus which are inherited from both parents, one from the mother and the other from the father

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.
How do the respiratory and circulatory systems work together to make gas exchange possible?Giving brainliest to first right answer
Answer:
Answer: The respiratory system moves air in and out of the body. When you breath in oxygen this creates oxygenated blood. The blood moves through the aorta which then distributes the oxygenated blood to rest of the body. The co2 then leaves the lungs when you exhale. Hope this helped. :)
Explanation:
Answer: [SAMPLE RESPONSE] The two systems work together in several ways. First, the respiratory system brings oxygen in the air to the alveoli in the lungs. The circulatory system then delivers the oxygen to the cells. Second, the circulatory system picks up carbon dioxide from the cells and carries it to the lungs, where it is released when we exhale.

A. Some inherited genetic mutations can be good for the offspring.
B. Different genetic mutations cause few forms of cancer.
C. Somatic mutations can be inherited from parents or acquired during life.
D.Genetic mutations that cause diseases are always passed on to offspring.
Answer:
A genetic mutation is a random change in the DNA that is passed on further generations of cells and or organisms. Genetic mutations are accidental changes in the DNA in the germ cells or early in the formation of the embryo.
Explanation:
Some inherited genetic mutations can be good for the offspring.
What is mutation?"It is a change in the structure of a gene."Gene is a structural and functional unit of hereditary.It is caused due to addition, deletion or copying of single base pairs of DNA.The mutation that occurs in somatic cells (cell other than stem cells or s ex cells) are not transferred from parent to offspring.A mutation should occur in s ex cell, in order for it to pass down to the offspring. So, the mutation that cause disease if occurs in somatic cell will not be passed to the offspring.The mutation can sometime result in the production of new proteins that are beneficial in nature.Not all the genetic mutation can cause cancer.Hence, the correct option is A. Some inherited genetic mutations can be good for the offspring.
