Although produced in both males and females, by the mid-teens, estradiol production in females is __________ times greater than
Tpy6a [65]

Answer: Although produced in both males and females, by the mid-teens, estradiol production in females is 8 times greater than it was before puberty, while testosterone production in males is 20 times greater than it was before puberty.

Explanation:

Puberty is the transition phase in which somatic growth and sexual development are completed, with the consequent acquisition of reproductive capacity. Estradiol is the most potent and abundant estrogen, it is secreted by the ovarian follicle granulosa cells and also by the corpus luteum. testosterone is the hormone responsible for the emergence of  secondary sexual characteristics, sperm production and increased  sexual drive, aggression, height growth and physical strength, among  others. There are many differences in body composition between both sexes, and those differences are also present in the hormones concentration. While estradiol is 8 times greater after puberty in females, this number is 20 times greatern in males, when we are talking about testosterone

A student is measuring the effect of different temperatures on the effect of enzymes in biological systems. What temperature ran
viktelen [127]

Answer:

A. 25 °C, 30 °C, 35 °C, 40 °C, 45 °C  

Explanation:

Each enzyme has a temperature at which it works best. In humans and many animals, that temperature is around body temperature (37 °C or 98.6 °F). Most enzymes are denatured and work poorly at 40 °C (104 °F).

That automatically eliminates Option B.

I would pick a temperature close to 37 °C (98.6 °F) and temperatures at intervals above and below that.

Option D is wrong because it includes no temperatures above body temperature.

Option C is wrong, because it includes temperatures of 45 °C and 55 °C, at which the enzymes will be denatured.

That leaves Option A as the best answer. It includes only one temperature above 40 °C.
