Answer:
5%
Explanation:
The adrenal cortex in both males and females produce a small amount of weak androgens. One of the major weak androgen secreted by adrenal cortex is dehydroepiandrosterone (DHEA).
Levels of dehydroepiandrosterone secretion exhibit changes with age. The dehydroepiandrosterone secretion increases till the age of 20-24 years and falls off with increasing age after the age of 30 years in both males and females. The DHEA production at the age of 80 years is about 5% of its secretion at the age of 30 years.
Answer: D
Explanation:
Because the heavy plow and its traction team was expensive tool and individual peasant farmers were not able to own it, it brought collective ownership and patterns of communal agriculture and communal animal husbandry.
The heavy plough required more energy to pull this resulted several families coming together to pool their oxen to form a team large and strong enough to pull the heavy plow. The resulting “ox-gangs” became an important social group.
Producing 100 kg of protein A requires calculating the necessary amount of soy, calculating the necessary inputs, looking for related information, and supervising the process.
To produce 100 kg of protein A with soybeans, I must look for information related to the cultivation of soybeans, what is the protein concentration in a soybean, and other aspects necessary for its maintenance and harvest.
In this search, I find that soy has a protein concentration of 50% or higher, so if I have to get 100 kg of protein, I must get at least 200 kg of soy.
So I grow some soybean plants in pots inside my house and I harvest their grains until I complete 200kg, supervising the whole process so that the plant does not suffer any disease or problem.

<u>Answer:</u>
<em>B) it requires only transfer RNA (tRNA) and ribosomes.</em>
<u>Explanation:</u>
After the <em>transcription of DNA to RNA</em> in nucleus of cell, the ribosomes synthesis protein and this process is known as the Translation. <em>For the translation process to occur, it requires transfer RNA (tRNA) and ribosomes.</em>
The translation process is also known as cell expression. The ribosomes help in translation by inducing <em>transfer of tRNA sequence of anticodon to codon of mRNA.</em>
