Answer:
Viruses are not alive
Explanation:
Viruses are acellular structures capable of performing some biological functions.
What are viruses?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.

Change that happens in a living organism because of a stimulus
Answer: A change in an organism's surroundings that causes the organism to react is called a stimulus (plural stimuli). An organism reacts to a stimulus with a response- an action or change in behavior. Another example is if you are cold, you shiver. The cold is the stimulus while the shivering is the response.
(The plural of stimulus is stimuli. Its verb form is stimulate, which typically means to spur into action or to invigorate.)

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.
What is HIV?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.

How energy from the sun is absorbed in earths atmosphere
Answer:
Explanation:
About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system
Answer:
The earth-atmosphere energy balance is the balance between incoming energy from the Sun and outgoing energy from the Earth. Energy released from the Sun is emitted as shortwave light and ultraviolet energy. When it reaches the Earth, some is reflected back to space by clouds, some is absorbed by the atmosphere, and some is absorbed at the Earth's surface.

During cell respiration, the reactants of glucose and oxygen are transformed into the products of carbon dioxide, water, and ATP. Which of the following cell transport processes would be relatively unaffected if a cell no longer had access to glucose? Choose 1 answer: Choose 1 answer: (Choice A) A The transport of calcium into a muscle cell via facilitated diffusion. (Choice B) B The transport of an amino acid into an intestinal cell from an area of low concentration to an area of high concentration gradient. (Choice C) C The transport of sodium against its concentration gradient in a brain cell. (Choice D) D The passive transport of a charged potassium ion (K^+ + start superscript, plus, end superscript) through a cell membrane.
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.
What is Cellular respiration?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.
