Which statement correctly describes interactions between organisms in this ecosystem?

2 answers:

6 0

An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.

Which statements describe functions of antibodies? Select two options.

vodomira [7]

Answer:

This question lacks options, options are:

A.They maintain the cell’s shape.

B.They regulate cell processes.

C.They protect the body from infectious agents.

D.They signal the immune system to destroy pathogens.

E.They speed up biochemical reactions.

F.They send electrical signals.

The correct answers are C and D.

Explanation:

B cells and T cells use different biological weapons to attack the pathogen. The first secrete proteins called antibodies, which are distributed via the blood or the exposed surfaces to the environment, such as mucous. Antibodies are glycoproteins that circulate in the bloodstream looking for antigens that cause some type of damage to the body. Antibodies recognize and neutralize pathogens in a highly efficient way. Once the antibodies are produced, they remain circulating in the bloodstream for several months, which generates immunity for a long period of time to a certain antigen, in other words, they are capable of recognizing other molecules (antigens) in a very specific way and forming stable complexes with them (immune complexes). Its appearance in plasma is part of the adaptive immune response, in what is known as a specific humoral response, constituting a very effective defense against pathogens.

What's mitosis and meiosis?

jeka57 [31]

Answer:

<h3>MITOSIS AND MEIOSIS*</h3>

Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. ... During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

<h3>What meiosis means?</h3>

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.

<h3>What is mitosis explain?</h3>

Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.

<h3>What is meiosis important?</h3>

Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.

<h3>What is Mitosis important?</h3>

Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

<h3>What is Mitosis means?</h3>

Mitosis is a process where a single cell divides into two identical daughter cells (cell division). ... The major purpose of mitosis is for growth and to replace worn out cells.

<h3>What Meiosis explain?</h3>

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins following one round of DNA replication in cells in the male or female sex organs.

Tpy6a [65]

Answer:

The correct answer would be - Having reliable access to food and being able to produce more calories per unit of land available led to population increase.

Explanation:

An increase in disease, sedentary agriculture, and increase in environmental degradation are three problem that is associated with the farming.

There are more benefits to continue agriculture is the ability of human kind to produce a food and access to plenty of food consistently which will led to increase the population.

Thus, the correct response would be - Having reliable access to food and being able to produce more calories per unit of land available led to population increase.
