Why must you avoid breathing or coughing on an agar plate?

Answers

Answer 1

Answer:

Explanation:

An agar plate is simply a Petri dish and it contains agar as a solid growth medium. It also contains nutrients for the culturing of microorganisms. Because of this reason, we must avoid breathing and coughing on these agar plates to avoid contaminating them. If they get contaminated we won't only see microorganism growth that we want to see for the experiment or test but also all the organisms from our body.

In poultry, black is dominant to white, but the heterozygote is blue. If you consistently

eliminated the black and white birds which appear in your flock of Blue Andalusians, how many

generations of such selection would it take to produce a true breeding flock of Blue

Andalusions?

Answers

Answer:

indeterminate

Explanation:

The answer would be an indeterminate number of generations.

The blue trait is a heterozygous trait. In other words, the blue allele does not really exist. Two different alleles team up to produce the trait, whereas, only two the same allelic conditions can produce a true-breeding flock.

Hence, it will take an indeterminate number of generations to produce a true-breeding flock of the Blue Andalusions.

The structures responsible for completing the breakdown of carbohydrates into usable energy for the cell are the

A. Nuclei
B. Mitochondria
C. Ribosomes
D.chloroplasts

Answers

Answer:

The correct option is;

B. Mitochondria

Explanation:

The mitochondria are the organelle of the cell bund to the membrane that are referred to as the cell powerhouse they function in the same manner as the digestive system, such that they take in raw nutrients which are broken down to produce energy containing molecules which makes up the majority of the chemical energy required for the various biochemical reactions of the cell in a way such that the energy they produce are stored in adenosine triphosphate (ATP) molecules.

Answer:

B. Mitochondria

Explanation:

The mitochondria are cellular organelles found in eukaryotic cells. They are structures involved in cellular respiration, which is the process whereby energy in form of ATP is synthesized for use by the cell.

Cellular respiration in eukaryotes occurs in stages including glycolysis, kreb's cycle and oxidative phosphorylation. All these processes combine to breakdown carbohydrates (glucose) into usable energy for the cell. The structures responsible for this process is MITOCHONDRIA.

Which of the following is an example of homeostasis?

Humans shiver when it is very cold.
We cover ourselves with a blanket when it is cold.
We take a shower to keep the body temperature low.
An air conditioner keeps the body at a normal temperature.

i think its A, B, or C

Answers

Answer:

Humans shiver when it is very cold.

Explanation:

"Homeostasis" is the ability of the body to regulate itself in order to maintain a steady state. This includes mechanisms that allow automatic adjustment when the need for it arises. Covering ourselves with a blanket, taking a shower and turning on the air-conditioner are "not self-regulated" activities because they are done "intentionally" by the person. It is only "shivering" that shows the body's regulation of heat.

When the environment is cold, the skeletal muscles of the body respond by rapidly contracting and relaxing. This is what you call as "shivering." It produces heat through "respiration." Thus, it helps increase the body temperature.
