Answer:
D
Explanation:
In ecology, abiotic components or factors are non-living chemical and physical parts of the environment. They include things such as sunlight, temperature, wind, water, soil and available nutrients (nitrogen and phosphorus).
Biotic factors are the living parts of an environment such as plants, animals, and microbes.
Abiotic components affect living organisms (biotic factor) and the functioning of an ecosystem. Together, abiotic and biotic factors make up the ecosystem. Both biotic and abiotic factors are related to each other in an ecosystem, and if one factor is changed or removed, it can affect the entire ecosystem. Abiotic factors are especially important because they directly affect how biotic organisms survive.
In this question, Phosphorus content of the soil is an abiotic factor affecting the growth of a vegetation (biotic factors).
<u>Answer</u>:
True - Homeostasis is regulated by two systems; the nervous system and the endocrine system.
False - Hormones released by the endocrine system are secreted through ducts.
The endocrine glands release hormones directly into the blood.
False - Steroid hormones bind to receptors on the surface of a cell.
The steroid hormones bind to nuclear receptors after they diffuse across the plasma membrane.
True - Hormones affect almost all cells and processes.
The effect of hormones are widespread and diverse. They control and integrate major processes in the body such as reproduction, development, the mobilization of the immune system etc.
False - Peptide hormones travel to the nucleus of a cell.
Peptide hormones never enter the target cell, They bind to a an external receptor on the membrane surface.
Answer:
it's gene's
Explanation:
A chromosome contains many genes. A gene is a segment of DNA that provides the code to construct a protein.
The nucleus is called the “control center” of the cell because it stores all of the genetic information (DNA), which is used to control the creation of other things in the body.
