Answer:
Variations in species led to evolution. Some species have desirable traits that are beneficial to their survival. Some species have undesirable traits that are not beneficial to their survival. E.g. peppered moths are not easily seen by predators because they camouflage with the bark, black moths are easily seen by predators so they are eaten. In the example mentioned, the peppered moths have a beneficial trait, this is also known as fitness, because the organism is fit for survival, unlike the black moths. Overtime the population of black moths decreases because they are not fit for survival, therefore the black moths cannot reproduce offspring that also have black wings. However, the population of peppered moths increases, because the peppered moths are able to reproduce offspring. Those offspring inherit their parents' traits, which make them have peppered wings too.
Answer:
D.They both produce new cells.
Explanation:
Meiosis and mitosis are both processes of cell division; however, they have many differences. Meiosis occurs in sex cells and produces haploids that can be fertilized. Mitosis occurs in body cells and produces diploids that replace old or damaged cells. Still, both processes result in the creation of new cells.
The correct formula for solving this question is: VC = IRV + ERV + TV, where VC is vital capacity, IRV is inspiratory reserve volume, ERV is expiratory reserve volume and TV is tidal volume. From the given information, TV =500, ERV =1200 and the standard IRV for male is 3100ml, therefore,
VC= 3100 + 1200 + 500 = 4800ml.
Answer:
C. a decrease in the chromosome number in every generation.

Scorpion cells undergo aerobic respiration, during aerobic respiration oxygen is used, and ATP is created.
During aerobic cellular respiration, glucose is absorbed with oxygen to form ATP, which can be used by cells. Carbon dioxide and air are formed as by-products. The overall extension to aerobic cellular respiration is: During cellular respiration, glucose and oxygen form ATP.
This process takes place in the mitochondria. So respiration occurs in animals and plants because both have mitochondria.
Aerobic respiration is respiration that requires oxygen while anaerobic respiration is respiration that does not require oxygen. Aerobic respiration consists of several stages, namely: glycolysis, oxidative decarboxylation, Krebs cycle, and the electron transport chain which have been discussed in the previous material.
