Answer:

1-They have their own DNA, which is separate from the DNA found in the nucleus of the cell. 2- both organelles use their DNA to produce many proteins and enzymes required for their function. 3- A double membrane surrounds both mitochondria and chloroplasts, further evidence that each was ingested by a primitive host.

In mice, black color (B) is dominant to white (b). At a different locus, a dominant allele (A) produces a band of yellow just be

artcher [175]

Answer:

Explanation:

Heterozygous mice at both loci would be BbAa genotype.

B (black) is dominant over b (white) but the presence of A results in agouti.

Crossing two heterozygous:

BbAa x BbAa

Progeny

9 B_A_ - Agouti

3 bbA_ - agouti

3 B_aa - Black

1 bbaa - white

Hence, 3 out of 16 progeny will be black in color.

In the fourth century BC, Aristotle observed a phenomenon in which he saw a circular shadow on the Moon. He argued that Earth wa

Answer:

a lunar eclipse

Explanation:

The shadow that Aristotle saw was caused by a lunar eclipse. At that time the sun, earth, and the moon nearly straight alignment caused the Earth's shadow to be reflected on the moon. This shadow is what ultimately led Aristotle to believe that the Earth was a sphere. This should not be confused with a solar eclipse which is similar but instead the sun, moon, and earth align in that order which causes the moon to completely block the sun to anyone on earth.

which of the statements is true of the gastric cavity of cnidarians? digestive enzymes released into the gastric cavity allow th

podryga [215]

This sentence is true in the case of gastric cavity of cnidarians - digestive enzymes released into the gastric cavity allow the consumption of whole prey such as fish.

Extracellular digestion is carried out by cnidarians, in which the cells that line the gastrovascular canal receive the nutrients and enzymes split down the food particles. With only one opening, the gastrovascular cavity that doubles as both the mouth and the anus in cnidarians acts as their only digestive system. There is only one entrance in the central gastro-vascular cavity, which serves as both a mouth and a drain for waste. Digestion occurs both within and outside of cells.

Cnidarians consume food through their lips, and the coelenteron then breaks it down. Waste products are subsequently eliminated either via the mouth or via cell surface via water circulation, while nutrients are then sent to other parts of the body for use.
