A cytoskeleton is:_______.

Biology
1 answer:
Softa [21]3 years ago
7 0

Answer: e

Explanation: Cytoskeleton is a microfilaments, intermediate filaments, and microtubules that provide support and movement for eukaryotic cytoplasm.

1. Prokaryotic cytoplasm lacks certain features of eukaryotic cytoplasm, such as cytoskeleton and cytoplasmic streaming.

2. The cytoskeleton provides support and shape to cell.

3. It help in transporting substances through cell.

4. It help in phagocytosis.

5. It help in cytoplasmic streaming that is movement of eukaryotic cytoplasm from one part of cell to another which help distribute nutrients and move the cell over the surface.

6. The study of the numerous interaction between microbes and host cell cytoskeleton is a very intense area of investigation on virulence mechanism.

the saclike shape of lipocytes allowing them to store more fat is an example of The following them in biology structure to the f
valkas [14]

Explanation:

This is an example of relating structure to function.

Cells sharing a similar origin, group together in the body to form tissues; these typically share physical features and are arranged in regular patterns cells within the human body can generally be placed into four groups:

  • epithelial which refers to sheets of cells covering exterior surfaces and internal organs;
  • connective tissue which functions to bind cells and organs together while protecting, supporting and integrating different regions.
  • muscle tissue which responds to simulation, allowing for movement and locomotion;
  • nervous tissue which responds to electrical impulses, allowing for communication between different regions of the body

Connective tissue are usually spread out in a formation called a matrix. The matrix contains lots of extracellular components which are made by cells within connective tissue; it mainly consists of a fluid ground substance which interwoven with fibers of protein. Connective tissues mainly contain cells, the ground substance and protein fibers; each of these are present in varying amounts related to the structure and function of the tissue

It is further classified in to loose and dense tissue types which exists in multiple variations; in the loose tissue, fibers are aggregated loosely without a regular arrangement and often contains large spaces. Additionally connected tissue also contains cell types like fibroblasts. The loose tissue types, like adipose act as shock-absorbers and allow water, nutrients and salts to diffuse throughout the tissue  to nearby tissue and cells.

Lipid droplets found in lipocytes, are organelles made up of a core of hydrophobic lipids. This is encased in a single layer of phospholipids which arrange themselves tightly and efficiently in a ball, with their hydrophilic heads facing outwards; while their hydrophobic tails face inwards. The phospholipid monolayer may also contain embedded proteins that at as special signals for recognition.

In lipocytes, one of these droplets may take up the intracellular space (white adipose) with the nucleus pushed to one side of the spherical cell- the cell takes the shape of the droplet, which allows storage maximization. They make up a type of loosely aggregated connective tissue, called adipose tissue,which function in cell signalling, as energy storage, and insulation.

Researchers hypothesized that cocaine is pharmacologically active in primate fetal brain when pregnant primates are administered
pav-90 [236]

Answer:

Option A, Glucose metabolism in the fetal brain increased

Explanation:

Usage of cocaine during pregnancy is prohibited. However, in case if cocaine is taken it disrupts the metabolism as it increases brain glucose metabolism to the level of an adult human being. Since glucose metabolism in brain is a sensitive process, any disruption in it can lead to unaccounted effects such as dysfunctional circulation, and pharmacological effect. Cocaine increases the dopamine by blocking the dopamine transporters thereby increasing the Vmax. Since the brain of a child has all kind of neurochemical components, cocaine intakes by a pregnant woman produces reinforcing effects in brain of fetus and also make it pharmacologically active

Hence, option A  is correct
