Keratins, neurofilaments, and vimentins are cytoplasmic intermediate filaments that are stable once formed. The nuclear intermediate filaments are disassembled and reformed during mitosis; this process is regulated by phosphorylation.
Phosphorylation is the connection of a phosphate group to a molecule or an ion in chemistry. This process, as well as its inverse, dephosphorylation, is common in biology and may be influenced by natural selection. Protein phosphorylation frequently activates a large number of enzymes. The inclusion of a phosphoryl (PO3) group in a chemical compound is known as phosphorylation. This reaction is critical in biological systems for the storage and transport of free energy via energy carrier molecules.
As a result, intermediate filaments can be found in incredibly durable structures such as hair, scales, and fingernails. Intermediate filaments' primary function is to promote cell cohesion and inhibit the acute fracture of epithelial cell sheets under tension.
Intermediate filaments are made up of smaller strands shaped like rods. Eight rods are aligned in a delayed arrangement with another eight rods, and these elements all twist together to form an intermediate filament's rope-like conformation.

Which Factor listed below is biotic. Bacteria, soil, sunlight, Rocks
Answer:
Bacteria
Explanation:
Hence, abiotic elements determine how organisms survive in an ecosystem. The main difference between biotic and abiotic is that biotic refers to all living things of an ecosystem while abiotic refers to all the non-living, physical and chemical things of an ecosystem.
Sunlight, rocks, and soil are all non-living.
The only biotic component mentioned is bacteria. Living things or their impacts are referred to as biotic factors. Single-celled creatures known as bacteria can live alone or in colonies.
They may be found almost anywhere, including the soil and the human body. All three kingdoms of life, Archaea, Bacteria, and Eukarya, contain bacteria that can reproduce. The terms "soil," "sunlight," and "rocks" all refer to abiotic elements, or nonliving parts of the environment.
Minerals, organic substances, gases, liquids, and living things all make up soil. Photosynthesis and other biological activities require sunlight, a type of energy that the sun radiates. Rocks are unbreakable, inorganic objects made of minerals.

Which type of macromolecules helps a cell brake down food? Lipids proteins carbonhydrates or nucliec acids
Answer:
The correct answer is - proteins.
Explanation:
All the food particles are broken down by specific protein molecules called enzymes. Carbohydrates are the macromolecules that are broken down by enzymes; amylase, lactase, sucrase, or maltase.
Proteins are macromolecules that are broken down with the help of the enzymes peptidase, pepsin. Lipids macromolecules are also broken down by lipase enzymes. Breakdown of these macromolecules provides energy for cellular activities.

The largest endocrine gland (s) that makes 3 hormones that affect the metabolism is the: *
A. pituitary gland
B. thyroid gland
C. pancreas
D. adrenal gland
Answer:
The largest endocrine gland (s) that makes 3 hormones that affect the metabolism is the: thyroid gland.
The largest endocrine gland that makes three hormones that affect metabolism is the Pancreas. Thus, the correct option for this question is C.
What do you mean by Endocrine Gland?An endocrine gland may be defined as a type of gland which consists of several organs that make hormones and release them directly into the blood so they can travel to tissues and organs all over the body. These hormones control many important functions in the body, including growth and development, metabolism, and reproduction.
The pancreas is the largest endocrine gland that significantly makes three hormones namely, Insulin, Glucagon, and Somatostatin. These hormones are actively involved in the regulation of metabolism by numerous mechanisms.
For example, insulin lowers the level of sugar in the blood, while glucagon increases the level of sugar by transforming its storage form.
Therefore, the largest endocrine gland that makes three hormones that affect metabolism is the Pancreas. Thus, the correct option for this question is C.
