If a mating between a black animal and a brown animal produced all black offspring, then the most likely hypothesis is that color is controlled by complete dominance and black animal parents are homozygous for this trait.
What is complete dominance?In genetics, complete dominance refers to the phenomenon for which one allele of a gene masks another allele of the same locus in order to express a given trait.
Therefore, with this data, we can see that complete dominance is caused when an allele masks the expression of the recessive allele in heterozygous individuals.

A couple who are close family friends of yours are concerned that their children may have a high risk of inheriting cancer from one of them. write a paragraph that describes the steps you would take to 1) Identify if either or both of the parents may contribute to the risk of cancer. 2) explain to the parents how genes may lead to the development of cancers that are not inherited and 3) how they could identify if an embryo ham the genetic components that will lead to cancer?
1.If either or both the parents have cancer,then the risk for contributing in cancer is very high.This can be analyzed with the help of family tree or pedigree analysis.But,its not always that if either one or both parents have cancer than offspring will get cancer.
2.Most cancers are not inherited,most cancers are occur due to genetic changes which a person acquire during his lifetime.The mutations which occur in genes can lead to development of cancer even its not inherited.
3.Tumors may arise from embryonic cells and can be identified by biopsy.

A normal allele for a gene has more base pairs than the mutated form of the allele. Which type of mutation occurred?
O base pair separation
O base pair insertion
O base pair substitution
O base pair deletion
Answer: Base Pair Deletion
Explanation:
If the normal allele has more than the mutated then that means nucleotides were lost so a deletion occurred.
Answer:Base Pair Deletion
Explanation:
We know this because it is stated that the normal gene has more base pairs than the mutated gene. In other words, the mutated gene has less base pairs than the normal gene, which means that base pairs must have been deleted during the mutation.

Explain one environmental drawback, not related to water use, of using the franking process to extract natural gas from shale.
One environmental drawback of using the franking process to extract natural gas from shale, is air pollution.
Methane is a main component of natural gas and is 25 times more potent in trapping heat in the atmosphere than carbon dioxide. A number of other air contaminants are released through the various drilling procedures, including construction and operation of the well site, transport of the materials and equipment, and disposal of the waste. Some of the pollutants released by drilling include: benzene, toluene, xylene and ethyl benzene (BTEX), particulate matter and dust, ground level ozone, or smog, nitrogen oxides, carbon monoxide, formaldehyde and metals contained in diesel fuel combustion---with exposure to these pollutants known to cause short-term illness, cancer, organ damage, nervous system disorders and birth defects or even death .

facilitated diffusion across a biological membrane requires ______ and moves a substance ______ its concentration gradient.
Facilitated diffusion is the process by which molecules diffuse across the plasma membrane with the assistance of membrane proteins like channels and carriers.
What main function of facilitated diffusion in membrane?Diffusion is the flow of chemicals across a biological membrane from an area of higher concentration to one of lower concentration, and it is facilitated by the usage of a transport molecule.
Because substances move in the direction of their concentration gradient, chemical energy is not directly needed.
Solutes diffuse through transport proteins in the plasma membrane when their diffusion is facilitated. A form of passive transport is facilitated diffusion.
Therefore, facilitated diffusion across a biological membrane requires transport proteins and moves a substance down its concentration gradient.

why is it important to calculate the diameter of the field when first using the microscope? bboldiitalicsuunderlinebulleted listnumbered listsuperscriptsubscript
You can calculate the real size of small objects with the microscope, so in a field, it is important to calculate the diameter.
What is a microscope?You may determine the actual size of things that are too tiny to be seen with the eye by measuring the microscope's field of view.
The largest useable field diameter in early microscope objectives typically ranged from 18 millimeters or less, but with a contemporary plan, it can occasionally approach 26 millimeters.
A microscope measurement can be used to classify an object into a certain size group or to determine whether the produced form of a specific feature is within dimensional.
Therefore to find the size of the smallest object in the microscope calculates the diameter of the field.

Discuss the excretory system and circulatory system and how they maintain homeostasis through feedback.
Regulating the body temperature happens through the process of thermoregulation. One system that is responsible for this is the excretory system. This process is an example of negative feedback. The body temperature tends to fluctuate within a normal range. So, the brain's control system and other parts of the body monitor this fluctuation and react to deviations from homeostasis.
The circulatory system is composed of blood vessels, including arteries, veins, and capillaries that are capable of dilation and constriction in order to help the body maintain its homeostasis. This system is also an example of negative feedback
What is the meaning of life?
Answer:
The meaning of life is to positively influence as many of the lives around you as possible.
Explanation:
Some people begin to feel a sense of dread when thinking about how little space they take up, and how long they will be alive, because it seems quite small and meaningless in the grand scheme of things.
That, however, is a result of the human brain rationalizing the value and worth of something by how long it exists and how much space it takes up. In reality, something does not need to take up much space, or exist for very long, in order to be worthy and meaningful.
For instance, a hamster is very small and may live only three years before passing of old age. However, if that hamster made a person happy — filled them with joy every day when they arrived home, gave them a reason to get out of bed even when they didn't feel like it, gave them the feeling of love even while being isolated — then it had a very, very meaningful existence.
Humans are very small, and we exist for very short amounts of time, but we have the power to feel and love and change our surroundings, and as long as we leave behind a legacy of even one smile, or even one life saved (no matter how small - a lizard, perhaps), or even one moment of hope, then we will have fulfilled our purpose, and that is all we could ever ask for.

When a blood sample is placed in distilled water for two hours. The blood cells gained water because they were placed in a hypotonic solution. Thus, the correct option for this question is B.
What is a Hypotonic solution?A Hypotonic solution may be defined as a type of solution that possesses a lower osmotic pressure than the solution through which it is compared. This type of solution generally has a lower solute concentration.
Distilled water significantly behaves hypotonic to the red blood cells. Due to this, the red blood cells swell, and red-colored pigment known as hemoglobin leaks from it as a cell increases its size. Due to this, the color of the solution changes into transparent red-pink.
Therefore, when a blood sample is placed in distilled water for two hours. The blood cells gained water because they were placed in a hypotonic solution. Thus, the correct option for this question is B.

Your answer is right.
First of all organic matter (organisms) sink to the bottom of an ancient ocean and mix with the inorganic. This cretes an organic-rich mud that can only form in still water enviroments. This mud cannot be exposed to too much oxygen.
If this shale is buried some kilometres, its temperature increases due to the location in the Earths interior. This increasing pressure and temperature transforms it into oil.
If the organic material is recycled by microorganisms, this process cannot occur.

Origin: East Asia, Southeast Asia, and some Pacific islands. This plant is invasive in North America.
Food: autotrophic because the Kudzu is a plant.
Important feature: Kudzu can cause environmental damage as it is an invasive plant. In fact, the environmental and ecological damage of Kudzu results from its competition with other plant species. In particular, kudzu competes with native flora for light and acts to block their access to this vital resource by growing over them and shading them with its leaves. Native plants may die as a result
i have to make a model for class and i don’t understand anything i have to do, can anyone help me complete the model?Part 2 and 3.
Answer: I think maybe you could make an illustration about the process of photosynthesis and cellular respiration. Maybe you could print some images like the sun, leaves, and molecules. In the molecules like oxygen, carbon dioxide, water, you could just make small circles. You can put it all together by adding arrows to show the next step of the process.
2. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP. Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. The bonds are broken in glucose, and this releases the chemical energy that was stored in the glucose bonds. Carbon dioxide and water are created as byproducts. This process occurs in mitochondria.
3. In the two processes, we can see that the products of one process are reactants of another – and vice versa. Glucose and oxygen – which happen to be the products of photosynthesis, are required to facilitate cellular respiration, while carbon dioxide – which is a by-product of cellular respiration, is required to facilitate the process of photosynthesis.
