A common way that humans pollute water is through the addition of nutrients (fertilizers and sewage) to water as nonpoint source pollution. These added materials are full of nitrogen and phosphorus, two nutrients that encourage the growth of aquatic producers, such as algae.
Answer: Since the industrial revolution, human activities have also resulted in an increase in natural greenhouse gases, especially carbon dioxide. An increase in these gases in the atmosphere enhances the atmosphere's ability to trap heat, which leads to an increase in the average surface temperature of the Earth.
Explanation:
Answer:
A. They are synthesized. is the correct answer.
Explanation:
protein synthesis is the method of producing proteins within the cell
In the endoplasmic reticulum on the surface of a rough endoplasmic reticulum, proteins are synthesized.
The rough endoplasmic reticulum is embraced with ribosomes on its external surface and it is involved in protein synthesis.
The protein enters the rough endoplasmic reticulum, by a pore and protein is folded in the rough endoplasmic reticulum, and after that, it is sent to the Golgi apparatus.
Answer;
The correct answer would be Rr.
In a monohybrid cross, the phenotype ratio of 3:1 is obtained only when both the parents are heterozygous for the trait.
In this condition, the heterozygous genotype would be Rr. The phenotype of both the parents would be round seeds (R) as the round is a dominant trait.
The cross of these parents would produce offspring with three types of genotypes RR, Rr, and rr in ratio 1:2:1.
Thus, the phenotypic ratio would come out to be 3 (round seed):1 (wrinkled seed).
