Answer:

It allows the cell to regulate the movement of materials into and out of the cell

Explanation:

This molecule is a saturated fatty acid. The cell membrane is made up of a phosphate head and three fatty acid tails that form a lipid bilayer arrangement.

This lipid bilayer regulates the entry and exit of substances into and out of the cell. Small non-polar molecules, like oxygen and carbon dioxide, are soluble in the lipid bilayer and can easily cross the plasma membrane. Small uncharged polar molecules, like water, can pass through the membrane by osmosis. Larger molecules such as glucose, or charged molecules like ions, require active transport to be passed across the cell membrane.

Answer:

Viruses are not alive

Explanation:

Viruses are acellular structures capable of performing some biological functions.

Viruses are parasitic structures made of an outer protein capsid and genetic material which are able to replicate in a living cell and thus cause infection in the cell.

Viruses hijack the replicative machinery of the host to produce copies of its own genetic material. A single infected cell is capable of producing thousands of viruses.

The virus only injects the nucleic acid inside the target cell, the envelope and capsid are left outside. The hijacked genetic machinery of the host produces further copies of the nucleic acid, capsid and envelope.

These structures are assembled to give rise to new viruses.

If a large number of viruses are synthesized rapidly, it results in cell lysis. This type of infection is called the lytic cycle.

If the virus genome incorporates with the host genome, it is present there silently and being replicated. Upon receiving an activation signal lytic cycle is activated. It is called the lysogenic cycle

Therefore, viruses are acellular structures capable of performing some biological functions.

The process of cell transport that would be relatively unaffected if a cell no longer had access to glucose is the transport of calcium into a muscle cell via facilitated diffusion. Thus, the correct option is A.

Cellular respiration may be defined as the chemical process through which the breaking down of food occurs with the liberation of energy. This process takes place in the excess of oxygen and constructs energy from carbohydrates (sugars).

The excess glucose delivers the required energy for the cell to perform its metabolic activities. But when the amount of glucose is not significantly present in the cell, the process of transport of calcium into a muscle cell via facilitated diffusion remains unaffected.

This is because the transport of calcium occurs due to paracellular passive transport without the utilization of energy. While the rest of the process requires energy for the transport.

And due to a lack of glucose, cells do not have the ability to derive energy in form of ATP.

Therefore, the process of cell transport that would be relatively unaffected if a cell no longer had access to glucose is the transport of calcium into a muscle cell via facilitated diffusion. Thus, the correct option is A.

HIV is a unique human RNA virus, capable of infecting cells of the immune system.  

Plz mark brainliest:)

It attacks and destroys certain cells in the bodies of its host organisms. Therefore, option (C) is correct.

HIV, or human immunodeficiency virus, attacks and destroys a specific type of immune cell called CD4+ T cells. These cells play a critical role in the immune system, and their destruction leads to a loss of immunity and the development of acquired immunodeficiency syndrome (AIDS). HIV is unique in that it specifically targets and attacks these cells, leading to a gradual decline in the body's ability to fight off infections and diseases.

HIV is primarily spread through sexual contact, but can also be spread through sharing needles or from mother to child during pregnancy, childbirth, or breastfeeding. HIV can lead to AIDS (Acquired Immunodeficiency Syndrome) if left untreated.

Answer:

All are methods to separate mixtures

Explanation:

A mixture consists of 2 or more substances that are mixed physically but not chemically. Hence, mixtures can be separated by any physical separation means which include but not limited to filtration, distillation, sieving, magnetization, and evaporation.

Filtration is usually used to separate suspended particles in a liquid using a membrane of a filter paper. Distillation is used to separate miscible liquids with varying boiling points by evaporating and condensing them back at their respective boiling points. Sieving is used to separate mixtures with varying particle sizes of individual components.

Magnetization is usually used to separate mixtures with, at least, one component with magnetic property. Evaporation is used to separate dissolved solids from liquids.

Hence, all the methods listed are used to separate mixtures.
