Answer:
inactive proteins can be activated by phosphorylation
Explanation:
Proteins are regulated after translation by the non-covalent binding of small molecules. These molecules include amino acids or nucleotides. A change in the conformation and thus, the activity of the protein is usually achieved when this occurs.
Proteins could also be regulated by phosphorylation which is the addition of phosphate groups of specific amino acids on the protein.
Answer:
The Golgi apparatus is especially developed in cells that have functions related to the secretion of substances, such as cells of the nervous or endocrine system.
Explanation:
The Golgi apparatus is the organelle responsible for most of the modifications that lipids and proteins undergo once their synthesis in the endoplasmic reticulum (ER) has been completed, that is, the Golgi apparatus is a cellular organ whose function is to manage the proteins synthesized by the endoplasmic reticulum in order to transform and export them to the rest of the body. It is made up of flattened cisterns (middle zone) with an entrance zone or face and an exit zone. The proteins enter the Golgi apparatus and are later transported to these cisterns where they are modified by enzymes.
Taiga is a winter type forest. Taiga is different then other ecosystems because other ecosystems are not has cold has Taiga. Taiga ecosystems can get has low has -70 °F (or -60° C)
But Taiga ecosystems can get has hot has 104°F (or 40°C)
Taiga ecosystems can get colder then tundra (which is another very cold too)
Some things that make the Taiga ecosystems unique is:
- Evergreen trees, the Taiga is COVERED with these.
Hope this helps!

Hereditary mutation - may be passed to another generation, occurs in gametes, variation that may enhance survival.
Somatic mutation - not passed from generation to generations, occurs in body cells.
Both- changes in DNA.
<h3><u>Explanation:</u></h3>
Mutations are defined as sudden changes in DNA that takes place by changing a particular nucleotide or a portion of DNA, or even a whole chromosome which has potential to change characters of an organism. Mutation was first proposed by Hugo de Vries who is also known as the Father of Mutation Theory.
Mutations can occur in any cell of body. It may occur in somatic cells, or in germ mother cells. But the mutations that occur in germ mother cells are actually the mutations that are carried forward by the gametes into next generations. Mutation in somatic cells get obliterated as the organism dies. And the Mutation in gamete cells are those mutations which are capable to cause variations in progenies which can led to better survival of the progenies.
All three domains include unicellular organisms, archaea, bacteria, and eukarya.
