Pleaseeee help!!! (psychology edge) Androgens and estrogens are hormones that impact the sexual response cycle. Write about the four phases of that cycle and explain how the two types of hormones are involved.
Answer:
Females and males each have some amount of the sex hormones, androgens and estrogens. In males however, androgens like testosterone is more dominant and in females estrogens like estradiol are more dominant. The hormones both affect the sexual response cycle. The sexual response cycle has four phases: desire, arousal, orgasm and resolution. The desire phase can last anywhere from a few minutes to hours and includes physical changes like an increase in muscle tension, heartbeats quickening, flushed skin, and an increased flow of blood to genitals. The arousal phase extends to the brink of the orgasm phase, during this phase the changes experienced in the desire phase are intensified along with blood pressure increasing. The orgasm phase generally only lasts a few seconds and is the climax of the sexual response cycle, some characteristics include: Involuntary muscle contractions and spasms, blood pressure, breathing, and heart rate at their highest point, a release of built up sexual tension, and flushed skin. During the resolution phase the body returns to normal, often a sense of wellbeing and fatigue is achieved. To begin the cycle a male need a certain amount of the androgen, testosterone, but high levels in females tend to lead to more sexual thought and desires, typically though, women have relatively low levels of testosterone. In women, estrogens, such as estradiol are more common. Estrogens are produced when a girl starts puberty and helps her reproductive cycle begin. A high level of estrogen in men can lead to a reduced sex drive, loss of hair, or trouble focusing, but a normal level in men is crucial to proper erectile function.

Which activity causes the least amount of wetland and estuary degradation when it occurs near the coast?
A. dune grass rehabilitation
B. hydrologic alterations
C. agricultural development
D. urbanization and land development
Answer:
The activity which causes the least amount of wetland and estuary degradation when it occurs near the coast is:
A. dune grass rehabilitation
Explanation:
This is actually a rehabilitation effort, unlike the other three options that cause land degradation. A dune grass rehabilitation accretes sand and minimizes the rates of beach erosion. The program tries to protect coastal infrastructure and upland properties from storm damage by planting vegetation, fencing off sensitive areas, blocking storm surge, creating dune walkways, and absorbing wave energy. During dune grass rehabilitation, activities that adversely affect the dunes are avoided.
Why is it important for farmers to add nitrogen to their field of crops?
O Plants use nitrogen to make nucleic acids which provide energy.
O Plants use nitrogen to make carbohydrates which provide energy.
o Plants use nitrogen to make proteins which help them grow strong and healthy.
Plants use nitrogen to make lipids which help them grow strong and healthy.
Answer:
itrogen is one of the key nutrients that plants need to grow, and it is naturally available in limited quantities. Therefore, the addition of nitrogen fertilizer is an important component of achieving high agricultural yields.
Explanation:
A student noticed that when a dog is cut, the dog periodically licks its wounds. Usually
after a few days, the wound begins to heal without ever showing
signs of infection. The
following steps outline the student's line of reasoning:
1. I wonder why the dog's wound doesn't become infected.
2. The dog's saliva must prevent the growth of infection-causing bacteria.
3. I'll obtain a bacterial culture and grow the same kind of bacteria in two identical
culture dishes. Once the bacteria start growing, I'll add dog saliva to only one of the
dishes and leave the other alone. I'll cover both dishes. Then I'll observe what
happens each day for a week.
4. Even after adding the dog saliva to one of the dishes, the bacteria continued to grow
in both dishes over the course of the week. However, the bacteria in the treated dish
grew more slowly than the bacteria in the untreated dish.
5. I think I'll try something else. I'll start with two identical culture dishes, as before, and
use the same kind of bacteria in each dish, but this time I'll treat one dish with dog
saliva before I add the bacteria. I'll observe what happens each day for a week. 12.
For the dog scenario above, what is the control

Which biomolecule provides cells with the most energy per gram?
lipids
proteins
nucleic acids
carbohydrates
Answer:
carbohydrates
Explanation:
Among the choices above, it is "carbohydrates" that provide the most energy per gram. Although both carbohydrates and proteins provide 4 calories per gram, carbohydrates contain the most number of glucose, which is being used in order for the body to have energy. So, if you want a quick way to become energetic, it is best to eat "healthy carbohydrates" than proteins.
Around 60% of proteins are converted into glucose while 100% of carbohydrates are converted into glucose. Therefore, carbohydrates provides more energy.

What would a graph of carbon dioxide absorption look like for this forested
area?
A. A line that goes up and down
B. An increasing line
C. A decreasing line
D. A flat line
Answer:
A decreasing line
Explanation:
The graph of carbon dioxide absorption look like a decreasing line for the forested area. Thus, the correct option will be C.
What is Carbon dioxide absorption?The absorption of carbon dioxide gas is an important process in many of the practical applications such as the reduction of greenhouse gases, separation as well as the purification processes in the chemical and the petroleum industries, and it also involve capturing of the radioactive isotopes in the nuclear fuel cycle and environment.
The carbon dioxide gas is captured and it can be put to the productive use in enhanced oil recovery as well as the manufacture of fossil fuels, building materials, and more, or it can be stored in the underground geologic formations in the environment.
Therefore, the correct option will be C.

Which of the following statements about exponential growth curves is true?
- a. Exponential growth curves are common for R-selected species.
Explanation:
The statement that is true about exponential growth curves is as follows:
Exponential growth curves are common for R-selected species.Thus, the correct option for this question is A.
What is an Exponential growth curve?An Exponential growth curve may be defined as a type of growth curve that significantly illustrates greater increases in the population of organisms with respect to time. It immediately represents the growth with extreme fast rates.
Exponential growth is followed by the continuous breeding population which contains more individuals than a similar population breeding annually. It includes examples like some insects, r-selected species, etc.
The shape of the exponential growth curve is J-shaped. It represents only fast growth rates. While the logistic growth curve shows fast growth rates followed by slow growth rates. It possesses a shape known as S-shape. It represents the growth rate of k-selected species.
Therefore, the correct option for this question is A.
