Answer:
The answer is A
Explanation:
The gene sequence inscribed in DNA, and in RNA, is composed of tri-nucleotide units called codons, each coding for a single amino acid. Each nucleotide sub-unit consists of a phosphate, deoxyribose sugar and one of the 4 nitrogenous nucleotide bases grouped into 2 categories, purine and pyrimidine.

Which of the following uses protein channels to carry large molecules and ions across the membrane without energy?
Answer: Simple Diffusion Across the Cell (Plasma) Membrane: The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.
Explanation: Large molecules like glucose or carbohydrates use proteins to help move across cell membranes. Some of the membrane proteins have carbohydrate Chains attached to help cells in recognize each other and certain molecules

chemical reactions that absorbs more energy than they release are considered to be
Chemical reactions that absorbs more energy than they release are considered to be endothermic.
What is endothermic reactions?Endothermic reactions involve the absorption of heat from the surroundings, resulting in a decrease in temperature of the surroundings. In these reactions, the reactants have lower energy than the products, and the difference in energy is absorbed as heat from the surroundings. Examples of endothermic reactions include the melting of ice, the evaporation of water, and the reaction of baking soda and vinegar.
In contrast, exothermic reactions release more energy than they absorb, resulting in an increase in temperature of the surroundings. Examples of exothermic reactions include combustion reactions and the reaction between acid and base to produce salt and water.

Ou are studying evolution by drift of coat color in two other wild populations of Dornish Sand Steeds. One population lives near Sandstone and the other near the banks of the Greenblood River. Knowing nothing else about these populations, which population would you conclude is more susceptible to genetic drift? Make sure you explain your reasoning and show your calculations. H
Answer:
The Sandstone community is somewhat more vulnerable to gene flow. A further explanation is provided below.
Explanation:
The risk of random mutations increases typically higher throughout communities with either a greater concentration. Genetic variation describes the probability including its loss of individual proteins from either the species. The lower the chromosomes, the increases the likelihood. Although women and men remain increasingly crucial for the sustainability of the community. Brown genotypes throughout Sandstone individuals will now have a greater risk of being attacked by gene flow.The process that describes the body's natural physiological response to stress is known as the
A. general survival response
B. general adaptation syndrome
C. physiological adaptation response
D. physiological survival syndrome
Answer:
General Adaptation Syndrome (GAS)
Explanation:
It is a theory that describes the stages of physiological changes that a body experiences when under stress. The three stages in order are:
The alarms stage
The resistance stage
the exhaustion stage
(This was paraphrased in my own words so that it can be paraphrased again by you)
The process that describes the body's natural physiological response to stress is known as the general adaptation syndrome.
What is stress?It is either emotional or physical. Stress is any event or thought that generates the feeling of irritation, anger, or nervousness.
How does the body respond to stress?The body responds to stress with a physiological response that is known as the "general adaptation syndrome."
How many stages are there to the general adaptation syndrome?It has three stages:

A child pulls a toy across the floor. What is the equal and opposite force for the force of the child pulling forward on the toy as described by Newton's third law? Choose 1 answer: Choose 1 answer: (Choice A) A Ground's normal force pushes up on the child's feet. (Choice B) B Ground's friction pushing on the toy (Choice C) C Child's feet's friction pushing on the ground in the opposite direction (Choice D) D Toy pulls on the child in the opposite direction
Answer:
D. Toy pulls on the child in the opposite direction
Explanation:
Newton third law of motion states that for every action, there is an equal and opposite reaction. This means that whenever an object 1 exerts a force (action force) on another object 2, object 2 exerts a force (reaction force) of equal magnitude but opposite direction on object 1.
According to this question, a child pulls a toy across the floor. Based on Newton third law described above, the toy will pull the child with an opposite force that is equal in magnitude. Hence, the equal and opposite force is: Toy pulls on the child in the opposite direction.

What are the parts and primary function of the male reproductive organ?
Answer:
The male reproductive system is mostly located outside of the body. These external organs include the penis, scrotum and testicles. Internal organs include the vas deferens, prostate and urethra. The male reproductive system is responsible for sexual function, as well as urination.
Explanation:
The majority of the male reproductive system is found external to the body. The testicles, scrotum, are some of these external organs. The vas deferens, prostate, and urethra are internal organs.
What is the male reproductive system?The male reproductive system is made up of internal organs including the prostate gland, vas deferens, and urethra as well as external genitalia like the testes, and scrotum.
The health of the male reproductive system and the hormones secreted by the brain determine a man's fertility and sexual characteristics. The male reproductive system is in charge of both urine and sexual function.
They create, retain, and move sperm and semen, which are the male reproductive cells (the protective fluid around sperm).
Therefore, sperm is released into the female reproductive system by them. Male sex hormones are created and secreted by them.

Scientists discover two planets orbiting a distant star. The average distance from the star to Planet A is 4 AU, and it takes 432 Earth days for Planet A to orbit the star. If it takes 1,460 days for Planet B to complete an orbit, what is the average distance from Planet B to the star?
Answer:
3.3
Explanation:
no reason for the explanation
Answer:
C. 9 AU
Explanation:
The period (T) of Planet A is 432365=1.2 Earth years. The period of Planet B is 1,458365=4.0 Earth years. Kepler's Third Law states that
a3=kT2
Substituting the known values of a and T for Planet A, we have
43=k⋅1.22
64=k⋅1.4
k=45.7
Using this value for k, we can solve for the distance from Planet B to the star
a3=45.7⋅4.02
a3=731.2
a=9.0AU
An alternative solution is to notice that a3T2=k for both orbits, which means that the ratio a3T2 is the same for both orbits. So, 434322=x314582. Solving this proportion gives x3=729, so x=9.0AU.
