Identifying an individual's genetically influenced health risks could increase their potential to achieve optimal health.
Answer:
Yes.
Explanation:
Yes, Identifying an individual's genetically influenced health risks could increase their potential to achieve optimal health because necessary steps can be taken in order to prevent the disease from more spreading and cause damaged to the body. Identification of genetical disease can be prevented to cause damage if the factors that triggers the disease can be avoided so we can conclude that identification of genetically influenced health risks can increase the chances of getting good health.

One reason why anabolic steroids can imitate the hormone testosterone is because
(1) anabolic steroids and testosterone both interact with the same cell receptors
(2) testosterone acts only on muscle cells
(3) females produce small amounts of the hormone testosterone
(4) an increase in testosterone in males using anabolic steroids increases male features
Answer:it’s 4 (an increase in testosterone in males unsung anabolic steroids increases male features
Explanation:
Anabolic steroids can imitate the hormone testosterone is because they both interact with the same cell receptors.
What do you mean by anabolic steroids?"Anabolic steroids are synthetic (man-made) versions of testosterone."It is used to enhance physical appearance by increasing muscle mass and decreasing fat.What is testosterone?"Testosterone is the male s ex hormone that is made in the testicles."It helps in regulating male s exual development and functions.What are cell receptors?"Structures found in the plasma membrane (surface) of cells that tightly bind specific molecules."It functions in information transmission.The anabolic steroids interact with same cells receptors as that of testosterone and results in increase of testosterone level causing increase in muscle mass.
Hence, the correct option is 1. anabolic steroids and testosterone both interact with the same cell receptors.

What are chromosomes?
Answer:Chromosomes are thread-like structures found within the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA). DNA is passed along from parents to children and carries the precise instructions that distinguish each living thing.
The word "chromosome" is derived from the Greek terms "chroma" and "body" (soma).

Quade is studying for an exam, which will cover neurons and action potentials. He has drawn a diagram that shows the segments of an axon, and he has noted that every time a segment fires, the _____ flood in from the outside of the cell, while the prior segment returns to its resting potential. Please choose the correct answer from the following choices, and then select the submit answer button.
Answer: positive sodium ions
Explanation:
This relates to the Action Potential which is what a nerve cell goes through when it needs to send information down the nerve cell to another cell and so on till it gets to the destination of the message.
The information is transmitted when the segments of the axon fire and when they do, positive sodium ions come in from outside the cell to the inside thereby making the inside positive. The previous segment would return to a resting potential when potassium ions which are negative, rush into the cell.

What is boiling factor ?
The boiling factor of a liquid varies in keeping with the carried out strain; the everyday boiling factor is the temperature at which the vapour strain is identical to the same old sea-degree atmospheric strain (760 mm [29.92 inches] of mercury). At sea degree, water boils at 100° C (212° F).
Thus it is well explained.

A. all of the alleles present in each parent's non-sex cells.
B. the alleles each parent can contribute in their gametes.
Answer:
B. the alleles each parent can contribute in their gametes.
Explanation:
This observation forms the second principle of inheritance, the principle of segregation, which states that the two alleles for each gene are physically segregated when they are packaged into gametes, and each parent randomly contributes one allele for each gene to its offspring.
Answer:
B. the alleles each parent can contribute in their gametes.
Explanation:
When a box is set up like this it is really a representation of MEIOSIS. The "H" and "h" on the top of the box really represent the alleles each parent can contribute in their gametes.
Deforestation occurs when large Amounts of trees are cut down and not replaced which of the following would result from deforestation
A. Decrease carbon in the atmosphere
B. Increased carbon in the atmosphere
Answer:
The correct answer is (B).
Explanation:
Deforestation occurs when large Amounts of trees are cut down and not replaced, which of the following would result from deforestation...
Increased carbon in the atmosphere
This statement is true because when trees become less abundant, the amount of oxygen being released into the atmosphere by trees via photosynthesis.
The circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.
What is Deforestation?Deforestation may be defined as the process of cutting down or eliminating trees in large numbers from our surroundings. This activity generally happens due to industrialization, wood extraction, urbanization, etc.
When the number of trees remains less in the environment due to deforestation or any other activity, the level of carbon dioxide in the atmosphere typically rises.
This is because carbon dioxide is considered the reactant of photosynthesis that is utilized by the plants along with water in the presence of sunlight and converted into oxygen.
But when the number of plants decreases, the level of carbon in the atmosphere increases, and the level of oxygen in the atmosphere decreases.
Therefore, the circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.

The idea of laissez-faire, or how much the government should do, is
DONE
Answer:
Laissez-faire means that the government does not interfere with people's right to pursue happiness.
The idea of laissez-faire, or how much the government should do, is debated heavily.
Explanation:
Laissez-faire is the main concept defended by economic liberalism and capitalism, mainly in the USA and other countries that adopt this type of concept. In a simple way, Laissez-faire can be defined as the separation of the State and the commerce of a region. This means, that in places where Laissez-faire is adopted, the State, ie the government, does not have the right to interfere in any type of commercial relationship and should only be responsible for guaranteeing property rights and consumer protection, otherwise, trade must regulate itself, within its own limits.
While many people see this policy as beneficial, preventing government from interfering with people's happiness, others believe that Laissez-faire is not beneficial and that government interference, or lack of it, should be discussed.
