Someone might argue against evolution and say that it’s “just a theory”. Why is this not a very good argument?

frozen [14]

Because there is countless amounts of evidence proving evolution. Where as most other beliefs and theory's have very little to back them up.

How does deforestation effect the oxygen cycle

sladkih [1.3K]

Trees remove some of this carbon dioxide from the air through photosynthesis and store that carbon in their tissues and in the soil. Deforestation reduces the removal component of this cycle, further increasing the carbon dioxide in the air. This results in an increase in temperature, an effect known as global warming.

A man with Type A blood marries a woman with Type AB blood. According to predicted outcomes based on genetics, their children ma

DochEvi [55]

Well,

We need to make a Punnett square. Assuming that the man has type A, not AO or AA blood, we will have a 1 x 2 Punnett square. We just have to take the A on the left and pair it with either the A on the left column or the B on the right column.

Therefore, the percent chance of having an AA genotype is 1 in 2 or 50%, while the percent chance of having an AB genotype is 1 in 2 or 50%. Thus, the possible phenotypes are 50% A type blood and 50% AB type blood.

I have attached the resulting Punnett square.

The process in which brain connections which are repeated become covered and insulated with a layer of fat increasing the effici

fiasKO [112]

Answer:

Myelination

Explanation:

Myelin is a fatty substance composed of lipids which surrounds the axons of the nerve cells in the central nervous system. The myelin is formed by the oligodendrocytes in CNS and Schwann cells in PNS.

The plasma membrane of the oligodendrocytes containing the myelin covers the axons of the neurons in spiral fashion thus proving a sheath around through the process called "myelination".

This myelin sheath protects the neurons from the external environment as well as insulates the neuron which increases the efficiency of the impulse.

Thus, Myelination is the correct answer.
