Answer:
False
Explanation:
When one of the glands is removed, the other continues to perform its function because they are independent entities that can continue to secrete hormones. This happens with the adrenal glands for example.
The correct answer is Option B: 3%.
In 2016, Sub-Saharan Africa, doubling time is 23.3 years, thus Growth rate is 3%.
<h3>What is doubling time?</h3>
- The doubling time is the time taken by a population to double in its size.
- This concept is applied to population growth, inflation, resource extraction, consumption of goods, the volume of malignant tumors, and many other things that tend to grow over time.
- There is an important relationship between the percent growth rate and its doubling time known as “the rule of 70”: to estimate the doubling time for a steadily growing quantity, simply divide the number 70 by the percentage growth rate.
- Therefore, Growth rate is 70 divided by doubling time (70/ doubling time).
- Here, Doubling time= 23.3 years.
- Growth rate= 70/23.3= 3%

Answer:
c. each primary spermatocyte produces 4 gametes while each primary oocyte produces one gamete.
Explanation:
The primary spermatocytes are the diploid cells that enter the process of meiosis during spermatogenesis. Meiosis-I in one primary spermatocyte produces two haploid secondary spermatocytes. Both of these secondary spermatocytes enter the second meiotic division and form a total of four spermatids.
On the other hand, the primary oocyte enters the process of oogenesis and gives rise to one secondary oocyte and a first polar body. Both of them are haploid. Meiosis-II in the secondary oocyte forms an egg cell and second polar body. Therefore, only one female gamete is produced by one primary oocyte.
