Androgens and estrogens are hormones that impact the sexual response cycle. Write about the four phases of that cycle and explai
hodyreva [135]

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.

If a person with O blood type produces offspring with a person with B blood type, then what percentage of their offspring will b
vlada-n [284]

Answer

The correct answer would be B) 50 %.

In humans, the blood group is determined by three alleles I^{A},I^{B}, and i.

I^{A} and I^{B} are co-dominant whereas  i is recessive to other two.

Thus, the genotype of a person with blood group O would be ii.

The genotype of a person with blood group B would be either I^{B}I^{B} (homozygous condition) or I^{B}i (heterozygous condition).

The crosses are shown in the image below.

There is only one condition in which the person can have offspring with blood group O that is, when the other parent is I^{B}i.

In this condition, the probability of an offspring to have blood group O is 50%.

In other condition, the probability of an offspring to have blood O is 0%.
