Answers

Answer:

it can change weather things will live or die

Ecological succession occurs when changes to either abiotic or biotic factors have an impact on an entire ecosystem. The replacement of one community of creatures, such as a plant or animal, by another is known as ecological succession. A forest fire is one illustration.

What biotic or abiotic factor can influence an entire biome?

An ecosystem's overall health is also influenced by biotic factors such as the diversity of consumers and the presence of autotrophs, or self-sustaining organisms like plants.

Abiotic variables have an impact on an organism's capacity for survival and reproduction. Populations are constrained in their expansion by abiotic forces. In an ecosystem, how these elements interact is crucial.

Therefore, it can change weather things will live or die.

Answer:

share a common ancestor

Explanation:

The similarity in their embryos and embryonic development suggests that reptiles, birds, and mammals share the same ancestor.

Similarity in the structure and development of embryo is one of the evidences that is been used by scientists to support the theory of evolution of species. According to the theory of organic evolution, all organisms are on earth as a result of descent with modifications from common ancestors.

Reptiles, birds, and mammals are all vertebrates. They share some basic characteristics and are thought to have shared a common ancestor before each group took different adaptive channels leading to their  differences as they currently exist.

Answer: The options are missing in the question,the options are;

A) Positive feedback will stop the release of this hormone.

B) Positive feedback will speed up the release of this hormone.

C) Negative feedback will speed up the release of this hormone.

D) Negative feedback will stop the release of this hormone.

The correct answer to the question is option D

NEGATIVE FEEDBACK WILL STOP THE RELEASE OF THIS HORMONE.

Explanation: The hormone the will be produced is known as Antidiuretic hormone (ADH).it is otherwise known as VASOPRESSIN.It is secreted by the posterior lobe of the pituitary gland.

The main effect of Antidiuretic hormone is to reduce urine output,(diuresis is the production of large amount of urine). Antidiuretic hormone acts in the distal convulated tubules and the collecting ducts of the nephrons of the kidneys,it increases their permeability to water and more of the glomerular filtrate is reabsorbed. Antidiuretic hormone secretion is determined by the osmotic pressure of the blood circulating to the osmoreceptors in the hypothalamus.

As osmotic pressure rises,for example as a result of dehydration, secretion of Antidiuretic hormone increases. With this,there is Increased reabsorption of water reducing the amount of urine produced.This implies that more water is retained in the body making the rise in the osmotic pressure of the blood to be low,for example,after a large fluid intake, secretion of Antidiuretic hormone is reduced,less water is reabsorbed and more urine is produced.

At high concentrations,for example after severe blood loss, antidiuretic hormone causes smooth muscle contraction, especially vasoconstriction in small arteries.this has a pressor effect,raising systemic blood pressure.

Answers

Our immune system’s function is to defend our body against pathogens. Two of the most important parts of our immune system are phagocytes and lymphocytes. Our phagocytes ingest the pathogens in a process called phagocytosis. Our lymphocytes produce chemicals called antibodies which can help to kill pathogens, kill pathogens themselves or neutralise any toxins produced. Sometimes, our lymphocytes create memory cells which remember the pathogen and retain in our blood even forever in some cases, to make us immune to the disease caused by the pathogen.

What is the purpose of a gene

Answers

Answer:

Genes are a set of instructions that determine what the organism is like, its appearance, how it survives, and how it behaves in its environment. Genes are made of a substance called deoxyribonucleic acid, or DNA. They give instructions for a living being to make molecules called proteins.

Explanation:

Genes tell your body how to make all its proteins. Each new cell in the growing embryo receives a full set of genes. But not every cell needs to make every protein and cells make some proteins only at certain times. Some genes are instructions for proteins that regulate the activity of other genes.

Groundwater comes to the surface and floods the land.

Answers

Answer:

D) groundwater comes to the surface and floods the land

Explanation:

Groundwater like water from river or lake comes to a land and before it has a chance to go back into the soil or evaporate, more water comes and floods the areas, thus the previous water stays and new water stays as well. If this cycle is repeated, a wetland will form.

wetlands form The tributaries flow into rivers.

How do wetlands form?

Wetlands is a flat area of ​​abundant herbaceous and/or shrubby vegetation that remains flooded most of the time. Swamps generally appear in areas where water flow is slow. In this way, the organic mass present in the waters decomposes on the spot.

With this information, we can conclude that wetlands are formed. The tributaries flow into rivers.
