Answer:
Punnet squares are basically how you can somewhat "predict" the outcome of gene pools.
Explanation:
As you can see, the capital letters (RY) are dominant alleles meaning they will be the trait that shows no matter what. the lower case letters (ry) show recessive traits and will only show if paired with another recessive gene.
Genotype is the actual makeup so the letters. (Rr, Ry, ry... etc.)
Phenotype is the trait that shows such as brown hair, blue eyes, etc.
Frequency is just how many times the gene shows up and put as a fraction or percent.
Answer:
Cellular respiration is the oxidation of food substances coupled with the release of energy (ATP). It occurs in the mitochondria of living cells.
b. 38 ATP in animals. In plants 2 ATP.
Anaerobic respiration is one that that takes place in the absence of oxygen while aerobic respiration is one that requires oxygen to take place.
Answer:
The correct answer will be option C- Convergent evolution.
Explanation:
The body shape of dolphins, sharks and penguins show similarity in structure sue to the same niche they inhabit which is the ocean.
All of them exhibit features which helped them survive in ocean-like streamlined bodies, fins and flippers. The dolphin, shark and penguins are not closely related but inherited similar characters (streamlined bodies, fins and flippers) due to the process of convergent evolution. These analogous features helped their survival in the same conditions.
Thus, option C- Convergent evolution is the correct answer.
Quick answer: Food enters the human digestive system through the mouth before then moving through the pharynx, esophagus, stomach, intestines, rectum and anus.
