Answer:
The digestive system of Frog, shark, chicken and cow are the following:
Explanation:
The digestive tract of frog is divided into foregut that consist of esophagus, stomach, duodenum, liver, pancreas, gall bladder and midgut/hindgut where intestine is present. The digestive system of frog comprise of oral cavity, pharynx, esophagus, stomach and intestine. The digestive system of chicken consist of beak, crop, proventricular, ventriculus, small Intestine, large Intestine and Cloaca. The digestive system of cow comprise of mouth, esophagus, rumen, reticulum, omasum, abomasum, small intestine and large intestine.
<span>The gum is probably lodged in the right primary bronchus. The right primary bronchus is an airway directly connected to the right lung. Bronchi are primarily responsible for moving air into the lungs, so when Keri choked on the gum, the gum would have blocked the air passage way required to breathe.</span>
Answer:
A lot of factors cause genetic variation in a population. The root of all genetic variation is mutations, which occur randomly.
A lot of genetic variation in fact results during meiosis, the process by which gametes (sex/reproductive cells) are formed. The 3 main ways are crossing over, independent assortment of chromosomes, and random fertilization. Crossing over occurs during Prophase I of meiosis, in which genetic material is exchanged between nonsister chromatids of homologous chromosomes. Independent assortment refers to the following: When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other. Random fertilization is where any sperm can fertilize any egg cell. The many combinations of eggs and sperms mean variation.
Another source of genetic variation include gene flow. Gene flow is where populations have their members enter other populations (migration), influencing the gene pool of populations. This source is more controversial, however.
Random mating can also increase genetic variation.
I think its C. The animal has a larger vacuole than a plant cell.
