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.

I believe the left chamber has a higher concentration of neon gas because it has more neon atoms in it, and the right chamber has a higher concentration of helium gas because it has more helium atoms in it.
What would happen to an animal cell with an internal salt concentration of 2% if it were placed in a salt solution with a salt concentration of 20%? (It helps to draw a picture) *
a.The cell loses water because there is a higher concentration of water inside the cell.
b.The cell loses water by pumping it across the membrane with the use of ATP
c.The cell gains water because there is a higher concentration of water inside the cell.
d.The cell stays the same because water will not move across the cell membrane.

1.) nucleus
2.)two
the answer is not cell for mitosis
Answer:
but what is the question?
Why only certain cell undergo mitosis
and why other cells undergo meiosis
Explanation:
Mitosis allows for cells to produce identical copies of themselves, which means the genetic material is duplicated from parent to daughter cells. Mitosis produces two daughter cells from one parent cell. Single-celled eukaryotes, such as amoeba and yeast, use mitosis to reproduce asexuallyand increase their population. Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. ... Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.

1. List the major ways in which humans are damaging the environment
2. Floods can devastate an ecosystem, however they can also have a positive impact. Please explain the positive impacts major floods can have on the ecosystem.
3. How do seasonal changes in temperature, water availability and sunlight affect ecosystems?
4. Propose 5 ways that humans can help minimise the negative effects both natural events and human impact can have on ecosystems.
Answer:
1. The large number of the pollution going into the air becaue of overfarming, and the high demand for unrenewable resources.
2. The positive impacts that floods can have is that they can water plants for places in drought like places such as California. For areas that are vastly dry, rain could be essential to humans, plants and animals in need of it.
3. These changes affect the ecosystem puts the ecosystems in a rather different situation than the ecosystem and those supported by it to adapt to the newcomings occuring of different seasonal changes and much more.
4.
-There can be alternatives to not destroying unrenawable resources.
-Use electrical cars that don't pollute the air.
-Be resourceful with their water and don't use more than needed.
-don't litter.
-recycle.
Define 3 of the major parts of the skeletal system and list the
function(s) of each (bones, ligaments, and tendon, cartilage.)
Answer:
Bone
The major functions of the bones are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and hematopoiesis. Together, the muscular system and skeletal system are known as the musculoskeletal system.
Ligament
Ligaments connect the ends of bones together in order to form a joint. They also assist in holding organs in place. Tendon: A tough, flexible and inelastic band of fibrous connective tissue that connects muscles to bones.
Tendon
A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.
Cartilage
Cartilage: This smooth and flexible substance covers the tips of your bones where they meet. It enables bones to move without friction (rubbing against each other). When cartilage wears away, as in arthritis, it can be painful and cause movement problems.

What can happen if a population of organisms disappears from the food chain in an ecosystem with low biodiversities, such as the tundra?
Answer: If the population of an organism dies out, then the animals on top of it on the food chain are going to die, since they will have no other food to rely on. Or, they will have to find a new source of energy if they do not.
This is why we should not try to kill any animals, even too much fishing can cause the same problem.

what is the kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s
Answer:
We can plug in the information for the ball into this equation to determine the kinetic energy. The mass is 0.5 kg and the velocity is 10 meters per second. So: KE = (1/2)(0.5)(10)^2. Thus the kinetic energy of the ball is 25 J
Explanation:
What is density of a liquid with mass of 17.4 and a volume of 20 mL ? Would this liquid float or sink at room temperature based on its density and the known density of water?

. Hope this helps but I can not answer the second part. Hope that it is beneficial to you anyway! :)
(Edit) This might help you figure it out: The relative densities of an object and the liquid it is placed in determine whether that object will sink or float. An object that has a higher density than the liquid it's in will sink. An object that has a lower density than the liquid it's in will float.

About how much of Earth’s surface is covered by the Pacific Ocean? Identify the locations of at least two major mountain chains that extend over more than one continent.
Answer: covering more than 30%
Explanation:
In a balanced ecosystem with predators and prey, if the prey population decreases then....?
Answer:
Predator population will also decrease
Explanation:
This is because the predators are dependent on their prey without the prey they would starve and die out so with less possible food the less of a population for what ever eats that prey which can lead to a chain reaction throughout the ecosystem however it is also the other way around too the more possible food the more chance for babies to be born and not starve to death.

What is the first aid for cramps?
Answer:
Take a hot shower
Massage the cramped area
Yup thats all i know
We all know that any cramp in our muscles is formed due to the secretion of lactic acid . This lactic acid is formed due to our muscles doing anaerobic respiration instead of aerobic respiration . Our muscles require oxygen to break down glucose itn energy and carbon dioxide . But our body muscles wont get this much needed oxygen due to which they will start to do anaerobic respiration where they produce energy without the usage of oxygen . When such a respiration happens lactic acid is secreted in our stomach , which makes our muscles start to form cramps . So we can say that tightness or soreness of muscles due to our muscles lacking oxygen is called as muscle cramps . So , a hot bath will be a very good remedy for cramps as it will let the oxygen pass through the body , thereby completely help the lactic acid turn into energy . When lactic acid breaks down completely to form energy the muscle cramps go away . Another first aid for cramps would be massaging the area with cramps . This will also increase the oxygen flow thereby making the lactic acid change into oxygen due to which the pain will go away . Another remedy for muscle cramps would be hot nor cold pads as they help ease the pain .

What landform is created when 1 oceanic plate and 1 continental plate move apart at a Divergent Boundary?
Answer:
Divergent boundaries also form volcanic islands, which occur when the plates move apart to produce gaps that molten lava rises to fill. Current research indicates that complex convection within the Earth's mantle allows material to rise to the base of the lithosphere beneath each divergent plate boundary.
