The amoeba excretes waste through _________ while a sparrow excretes waste through __________.
​

Answers

Answer 1

Answer:

The amoeba excretes waste through Contractile Vacuole while a sparrow excretes waste through Cloaca.

​

Explanation:

In some unicellular eukaryotic organisms (e.g., amoeba), cellular wastes, such as ammonia and excess water, are excreted by exocytosis as the contractile vacuoles merge with the cell membrane, expelling wastes into the environment.

Birds, unlike mammals, do not have separate exits for urine and feces. Both waste products are eliminated simultaneously through the cloaca. While mammals excrete nitrogenous wastes mostly in the form of urea, birds convert it to uric acid or guanine, which reduces water loss in comparison.

Explanation:

Two heterozygous dominant parents for attached earlobes are crossed to predict the traits of their offspring. What is the ratio of attached earlobes to unattached earlobes in their offspring?

A - 3:1
B - 1:3
C - 2:2
D - 4:0

Answers

Answer:

A - 3:1

Explanation:

In order to determine what number of offspring will have attached earlobes, we must make a Punnett table. We know that attached earlobes are the dominant gene, and we know unattached earlobes are recessive.

| P | p

——————-

P | PP | Pp |

——————-

p | Pp | pp |

As we can see, only one out of the four squares has two recessive genes. Therefore, our answer would be A - 3:1.

(3:1)would be the right answer to you mr question
