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.

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

⦁ What technique can be used as the first step to identifying bacteria?

Answers

Answer:

Isolating a single bacterium species is the first step in identifying the bacteria possibly responsible for a disease process.

Explanation:

Following isolation, one of the first steps in identifying a bacterial isolate is the Gram stain, which allows for the determination of the Gram reaction, morphology, and arrangement of the organism.

Which is true of genes?

O They are sections of DNAthat produce the proteins that control an organism's characteristics

O They are proteins that produce sections of DNA which control the cell's activities

O They are features that can be observed rather than measured.

O They are the same as traits which show up in an organism if they are dominant​

Answers

the correct answer is: they are sections of DNA that produce the proteins that control an organisms characteristics

The statement that is true about Gene is that They are sections of DNA that produce the proteins that control an organism's characteristics.

What is Gene?

Gene refer to an hereditary unity which is transmitted from parent to their offsprings and it is transferred from one generation to another.

It is the major constituent of an organism DNA.
