Answer:

eukaryotes

Explanation:

Acheas and Eucariontes have a common ancestor, which justifies the vast similarity in the structure and cellular function of each individual. These similarities have already caused confusion in the academic community that has already joined the two organizations in a single group, however, it is now known that the similarities are due to a common ancestor.

During photosynthesis, oxygen is converted to carbon dioxide. True False
andreyandreev [35.5K]
This is false. Carbon dioxide is taken in, and oxygen out. Oxygen is not converted to carbon dioxide. It is a waste of the chemical reaction taking place, just like carbon dioxide is a waste in the respiratory process for us.

I hope this helps!

galina1969 [7]

Answer:

The student is wrong, spermatozoa are germinal cells and therefore mitochondrial mutations (likewise genomic nuclear mutations) are inherited by offspring

Explanation:

Although the probabilities of inheriting a mutation from a single sperm cell are low, it since an organism produces millions of sperm cells throughout its life span, the mutations in the germinal cells (i.e., sperms and ovules) are inherited by offspring

Why will many species of bird migrate to warmer climate during the winter
Doss [256]
Bird migrations began with the recession of the glaciers during the ice age. You will notice a great increase in insects in the spring time and early summer.The birds moved North to take advantage of this increase in the food supply that followed the warming in the spring and early summer. Their reproductive organs temporarily developed so they could lay eggs and raise a family. Look at the early flush of Night crawlers in the moist times of the early rains. By mid summer most of the insects have matured, mated and died. Their eggs have hatched and turned to larva and moved underground until next spring. The shortening of the days causes the reproductive functions to decrease and signals the birds that the food will soon become scarce. They move back to the area that makes it the easiest to find food and avoid freezing. which of course is the warmer climates nearer the equator. Not all birds move past the Tropics at approximately 30 degrees. Some like Chickadees may move down from Mi or Mn or Canada only as far south as Indiana. Some migrations may be quite short. For example from the mountains down to the plains. They don't generally reproduce in the warmer winter climes they migrate to. In the spring time they migrate along paths of the retreating glaciers. As the climate warms away from the tropics the birds follow the emerging insects etc to the birds selected breeding grounds.with increased insects and longer days to feed the hatching's. It is necesary to understand why they move to cooler climates in the summer to under stand why they move to eh warmer ones in the fall. As the days shorten the food supply dwindles and the babies have fledged. They move to warmer climates in winter to rest and refuel for the next years migration.
