Explanation:
The enhanced greenhouse effect, sometimes referred to as climate change or global warming, is the impact on the climate from the additional heat retained due to the increased amounts of carbon dioxide and other greenhouse gases that humans have released into the earths atmosphere since the industrial revolution.
Mechanical stress applied to bone increases osteoblast activity in bone tissue, and the removal of mechanical stress decreases osteoblast activity.
Explanation:
Osteoblasts are cells , that are produced in the bone marrow and are responsible for formation of bones and bone matrix.
Whenever a mechanical stress is applied on the bones , a series of reactions are triggered. As a result the activities of osteoblast increases to synthesize more and more bone matrix to provide strength.
Again on the other hand a decrease in mechanical causes a decrease in the activities of the osteoblasts.

In the process of the nitrogen cycle. <span>
The nitrogen cycle is a biogeochemical succession process of nitrogen that involves: fixation, ammonification, nitrification, and denitrification. Like any other biogeochemical cycles. This process undergoes and affects the biological, geometrical and chemical aspects in the ecosystem and the abiotic and biotic community. Hence, the nitrogen cycle leads the abiotic component –nitrogen- to contribute to the biotic community, decomposition and primal production. Further, it becomes an essential part of the environment because some life components are contains it, similarly, amino acids, nucleic acids in RNA and DNA. </span>
Basically it will just regenerate its body and continue being a starfish no matter how much you cut from a starfish it will regenerate
The correct answer is R-r.
Heterozygous is where the alleles of diploid organisms are different.
Alleles are variations where DNA sequence of gene varies from one individual to another. Other genes may have one allele because if there is low variation. There are genes where by one alleles may be common and others are rare.
Sometimes it can be a disease which causes variation and others may be a healthy. One allele is being inherited from male parent in diploid organisms and others from female parent.
