Answers

Answer 1

Answer: The answer would be C physical weathering because heat and the breaking of the rock can be the result of physical weathering, and the other answers would not make sense.
Biological weathering would be the breaking down of the object due to a form of life (incorrect answer),
erosion is the carrying away of something (incorrect answer),
and chemical weathering would be changing the identity of the substance(incorrect answer).

A fisheries management official recommends that long line fishing in a certain area be prohibited during the spring and summer season of the year. What is the most likely reason for this?Prevent the catching of sea birds during their nesting and breeding season.
Enable the fishing fleet to catch younger fish.
Maximize fishing profits during peak tourist season.
Avoid fishing competition with foreign fishing fleets.

Answers

The correct answer for this question would be the first option. The reason that is most likely why fisheries management official recommends that long line fishing in a certain area be prohibited during the spring and summer season of the year is to prevent the catching of sea birds during their nesting and breeding season. Hope this answer helps.

Answer:

Prevent the catching of sea birds during their nesting and breeding season.

Hydrochloric acid is secreted by which of the secretory cells of the stomach?A. chief cells
B. parietal cells
C. serous cells
D. mucous neck cells

Answers

Hydrochloric acid is secreted by B. parietal cells.

What role do parietal cells play?

Parietal cells are involved in gastric acid secretion and help digest food, absorb minerals, and fight harmful bacteria.

Parietal cells (also known as oxygen cells) are gastric epithelial cells that secrete hydrochloric acid (HCl) and intrinsic factors. These cells are found in the gastric glands in the lining of the fundus and in areas of the body of the stomach.

There are several cell types in the stomach, each with a specific mechanism of action. Chief cells produce pepsinogen, which is converted to pepsin by hydrochloric acid in the stomach. Parietal cells produce hydrochloric acid, which enables this conversion.

Which feature do viruses have in common with animal cells

Answers

The unique common feature between viruses and animal cells is the use of DNA as hereditary material, in fact viruses are only hereditary material with a protein "coat" around them, this is why they need to infect cells to reproduce.

Both viruses and animal cells possess genetic material in the form of nucleic acids.

Which feature do viruses have in comon with animal cells?

Viruses are infectious agents that consist of genetic material (either DNA or RNA) enclosed within a protein coat called a capsid. Some viruses also have an outer envelope derived from the host cell's membrane. Viruses lack cellular structures and cannot carry out essential life processes on their own. They depend on host cells to replicate and produce new viral particles.

Animal cells, on the other hand, are the fundamental units of structure and function in animals. They contain a nucleus that houses the genetic material, which is composed of DNA. Animal cells also possess various organelles and structures that carry out specific functions within the cell.

Despite their fundamental differences, viruses and animal cells both have genetic material in the form of nucleic acids. However, it is important to note that while animal cells use their genetic material to carry out the necessary functions of life, viruses rely on host cells to replicate and produce new viral particles.

How many chromosomes are in a haploid cell?

Answers

First you must know that a diploid cell has double the amount of chromosomes of a haploid cell. A diploid cell has 46 chromosomes. When we divide 46 by 2 you get 23. This means that there are 23 chromosomes in a haploid cell.

Hope this helped!

~Just a girl in love with Shawn Mendes

Answer:

Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.
