It becomes more alkaline where pH will be more than 8
As the human population increases, stressors are being placed on the environment. <u>Decreases in availability of </u><u>natural resources</u> is one consequence of this growth.
Population- A population is the total number all organisms belonging to the identical species that really are present in a given location at the same time and have the potential to interbreed. Individuals need to be able which can mate with other members of a population and give birth to viable children for interbreeding to take place.
Natural Resources- Without human assistance, natural resources are present on planet. We can get water, wood, food, and energy from natural resources. Without natural resources, life is not conceivable. Oil, coal, natural gas, metals, stone, and sand are examples of natural resources.

Answer:
D. The genotype and the environment both affect phenotype.
Explanation:
Phenotype is the outward expression or make up of an organism. The phenotype is simple the physical outlook of an organism. It is as a result of the combination of two major factors which are the genetic make up(genotype) and the environment. When both combines, an organism's pheontype is built and produced.
If the environment is lacking, a gene might not successfully express itself in an organism. Also, an organism might have the right environment but the gene is lacking.
Two similar chromosomes that you inherit from your parents are called homologous chromosomes.
During sperm penetration, human eggs are still surrounded by follicular cells.
Therefore, the correct answer is Option D.
<h3>What changes does egg undergo for fertilization?</h3>
- An egg goes through a few changes at the hour of sperm penetration during fertilization.
- These progressions happen at the cell surface, in development, physiology and gene expression.
- For fertilization, a sperm should combine with the cell membrane and afterward infiltrate the egg cells.
- Infiltration through the egg cell or extracellular matrix (ECM) is a troublesome task.
- The acrosome of the egg goes through acrosomal reaction to get through the hard shell of cell.
- To go through the follicle cells encompassing the egg or oocyte, the sperm discharges hyaluronidase enzyme.
- This chemical isn't delivered until the sperm comes into contact with the egg cell's zona pellucida.
