Answer:
Referred to as cellular s*icide
Explanation:
Programmed cell death (sometimes referred to as cellular s*icide) is the death of a cell as a result of events inside of a cell, such as apoptosis or autophagy.
Answer:
Mendel's law of independent assortment
Explanation:
Gregor Mendel is a really important figure in genetics, his work on pea plants provided us with many of the fundamentals of genetics that we still have today!
Mendel proposed 3 laws:
1. The law of dominance - this law states that where there are two different alleles (heterozygous) the organism will always express the dominant trait over the recessive trait
2. The law of segregation - this law states that offspring will inherit one allele from each parent, because allele pairs separate in the process of meiosis, such that each gamete contains 1 allele of each trait. When the zygote is formed, it contains an allele from each parent.
3. The law of independent assortment - this law states that traits are independent from one another at the time of gamete formation. The genes are segregated separately from one another, as the presence of one does not impact the presence of another.
This example shows that all combinations of the height and color allele are possible, and therefore nicely demonstrates the law of independent assortment
“Biomagnification or biological magnification is the process of accumulation of certain chemicals in living organisms to a concentration higher than that occurring in the inorganic, non-living environment.”
Human beings occupies the top place of most trophic level and we know that concentration of harmful chemicals increase as we go above the trophic level. Therefore human beings are most adversely affected by biological magnification.
Humans may also be affected due to the consumption of fish and shellfish.
Answer:
D) It is a coordinator of the processes of glycolysis and the Krebs cycle.
Explanation:
Phosphofrutokinase is a very important enzyme in glycolysis, as it acts as a regulating factor of the glycolytic process that catalyzes a phosphorylation: the conversion of fructose 6-phosphate and ATP into fructose 1,6-bisphosphate and ADP. This is an allosteric enzyme, which is activated by citrate and ADP, but is inhibited by the presence of ATP that endorses the enzyme that its work is not needed at the moment. Although very important in glycolysis, this enzyme is not part of the krebs cycle.
