Answer:
Gene regulation refers to the regulation of expression of a particular gene in a cell that is, it increases or decreases the expression of a particular set of genes in a particular cell.
In multicellular organisms, gene regulation plays a crucial role in cell differentiation and maturation.
It enables the formation of different types of cells or tissues from a single type of stem cells that is, it enables the formation of a multicellular organism from a single cell zygote.
For example, muscle cells, nerve cell, skin cell et cetera all arise from a single-celled zygote. It is possible due to highly regulated gene expression.
All cells contain the same genetic information (DNA) but different sets of genes are expressed in different specialized cells.
The functional groups determine the shapes of macromolecules and this in turn determines their functions. ... Proteins have complex structures caused by interactions between the functional groups. A change of a single amino acid can make a major change in the function of a protein.
Answer:
Beside the intensive loss of forest cover [2], fragmentation of the pristine remnants further affects species [3] and limits their ability to move into adequate areas. Thus the ability to cope with altered landscapes is crucial for the persistence of a species, especially in the face of climate change.
Kingdom Fungi. Mostly are single celled bacteria, they emit sunlight by means of photosynthesis that allows them to make food for themselves and also they have another food serve except for the sunlight and eats some single cell organism and that would call them as heterotrophic
Answer :Adrenocorticotropic hormone
Explanation:
Adrenocorticotropic hormone (ACTH) is produced by the pituitary gland. Its key function is to stimulate the production and release of cortisol from the cortex (outer part) of the adrenal gland.
