Why is there Cholesterol in your cell membrane?

Biology

Answer:

Cholesterol functions to immobilise the outer surface of the membrane, reducing fluidity. It makes the membrane less permeable to very small water-soluble molecules that would otherwise freely cross. It functions to separate phospholipid tails and so prevent crystallisation of the membrane.

Cholesterol functions to immobilise the outer surface of the membrane, reducing fluidity. It makes the membrane less permeable to very small water-soluble molecules that would otherwise freely cross. It functions to separate phospholipid tails and so prevent crystallisation of the membrane.

It helps to restrict the passage of molecules. Since it is small, it can work to fit and block off water soluble molecules from diffusing into the membrane.

Homeostasis depends on the activity of body systems to adjust a variable. Because our bodies work so well to maintain variables
NNADVOKAT [17]

Answer: body systems that can directly impact fluid balance includes:

b)urinary system

c)respiratory system

f)sweat glands.

The correct option is B, C and F.

Explanation:

Homeostasis is the mechanism by which the body maintains a steady ( constant) internal physical and chemical conditions. The following variables needs to be kept in equilibrium for optimal functioning of the body system. They includes: the body temperature, fluid balance, blood sugar levels. These variables are in turn controlled by one or more regulatory systems which includes;

- urinary system:when blood volume gets too low or blood electrolytes get too concentrated, the kidneys can retain water thereby decreasing urine output. When blood volume or pressure is too high, the kidneys can excrete more water thereby increasing urine output.

- sweat glands: this regulates both fluid and temperature.

I hope this helps. Thanks

Match these items. 1. taxonomic category within a kingdom fermentation 2. plant that lives on decaying organic matter host 3. br
Sonja [21]

1. taxonomic category within a kingdom-phylum

This taxonomic category is at level below Kingdom and above Class (e.g Arthropoda, Chordata, Mollusca)

2. plant that lives on decaying organic matter-saprophyte  

Saprotrophic plants or saprophytes use saprotrophic nutrition meaning that have extracellular digestion to process death organic matter.

3. break down of complex molecules into simpler ones- fermentation  

Fermentation is a metabolic process that breaks down organic substrates in order to obtain energy. These processes are performed without the presence of oxygen (anaerobic processes).

4. multi-nucleated thread-like structures of fungi hyphae

This is one of the basic structural unit of fungi-long, filamentous structure that can form network-micelium. It is used for vegetative reproduction.

5. mycelia responsible for obtaining food from non-living organic material rhizoids

Rhizodis are unicellular or multicellular stuctures (branching hyphae) found in fungi that are similar to root hairs of plants. These structures are involved in saprotrophic nutrition of fungi.

6. asexual reproduction of yeast budding  

Budding is a type of asexual reproduction in which a new organism develops from some generative anatomical part of the parent organism.

7. a group of hyphae mycelia

Mycelum is fungi’s vegetative body that consists of network of branching hyphae.

8. reproductive cells which can tolerate bad conditions spores

Spores are reproductive structure, part of the fungi life cycle, that can be involved in sexual or asexual reproduction, vary in structure that are formed in. Spores are usually haploid and unicellular.

9. structures which house the reproductive formation fruiting

Fruit is a structure in flowering plants that contains seed and it is responsible for seed dispersal and nutrition.

10. mutually positive relationship between two species symbiosis  

Symbiosis is biological interaction between two species that can be mutualistic, commensalistic, or parasitic. More specifically, symbiosis refers to positive interaction for both members of it.

11. plant or animal which supports a parasite host

Parasitic relationship between species is the one in which organism (the parasite), lives on or in another organism (host).This relationship is positive for parasite but negative for the host.
