Answer: NATURAL SELECTION is the term used to describe the greater relative survival and reproduction of individuals in a population that leads to evolutionary change.
Explanation: Those individuals with characteristics (either physical or behavioral) that give them an advantage in a particular environment, are more likely to thrive and survive to breed, passing along their characteristics. Likewise, those who are disadvantaged are less likely to survive to breed and pass along their traits.
Mitochondria produce ATP through process of cellular respiration—specifically, aerobic respiration, which requires oxygen. The citric acid cycle, or Krebs cycle, takes place in the mitochondria. This cycle involves the oxidation of pyruvate, which comes from glucose, to form the molecule acetyl-CoA. Acetyl-CoA is in turn oxidized and ATP is produced.
Answer:
The main functions of the integumentary system is to protect the body from outside environment. It includes skin, nails, nerves and hair. Skeletal system is made of bones which provides shape and support to the body.
Explanation:
Homeostasis refers to the balance or equilibrium condition of the body. If the homeostasis of the body is disturbed, the body will not be able to perform properly. For example, heat is produced in the body during energy production. If this heat is not removed from the body, the cells and organs performance is badly affected because they require optimum temperature for functioning.
Answer:
Answer is A. Increases in brain size are primarily due to myelination and increases in the number and size of nerve endings.
Explanation:
Myelination is the process which leads to the formation of myelin sheath around axon or nerve impulse.
The myelin formed is a coating rich in fat, that is found around the axon of neuron. It protects the neuron, and at the same time helps the neuron to conduct signals or impulses move quickly and efficiently.
Answer:
Divides into two cells
Explanation:
During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase. During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. The cytoplasm is usually divided as well, resulting in two daughter cells.
