Because both introduce substance that harm organisms. All the other ones are wrong because<em> eutrophication</em> is a natural process that involes little to<em> no human interference . </em>
<span>The correct answer is testes. Gametes are sex cells, meaning that when the sex cell from a male joins with the sex cell from a female, reproduction occurs. In males, the sex cells are sperm and in females, they are eggs. The formation of these sex cells occurs in the testes for males and in the ovaries for females. So, the second option is incorrect because ovaries belong to females, gametes are incorrect because they are the product of the gamete formation organs, and the last option is incorrect because oogonia is a female sex organ for a specific type of algae. </span>
Answer:
1. Weaker
2. Continuous
Explanation:
A tumor suppressor gene codes for retinoblastoma protein (pRb). The retinoblastoma protein binds to transcription factor E2F when DNA damage is detected. The E2F bound to pRb can not stimulate expression of genes that code for proteins required during the process of DNA synthesis. The cell can not enter the S phase.
On the other hand, when the retinoblastoma protein is phosphorylated by cyclin E-CDK2, E2F transcription factor is free to stimulate the expression of genes required for DNA synthesis and the cell proceeds from G1 to S phase.
When the mutated retinoblastoma gene code for a protein that serves as phosphorylated protein, it will not be able to bind strongly with E2F and there would be continuous expression of genes required for S phase.
Circulation of chemical nutrients such as oxygen,carbon,phosphorus,nitrogen,water, and calcium. Through the biological and physical world are known as biogeochemical cycles.
