describe the possible long term effects of HIV on the immune system
Explanation:
HIV attacks a specific type of immune system cell in the body. It's known as the CD4 helper cell or T cell. When HIV destroys this cell, it becomes harder for the body to fight off other infections. When HIV is left untreated, even a minor infection such as a cold can be much more severe.

3. Habitat Destruction
5. None of the Above
Explanation:
Answer:
1. d
2.c
3.a
4.a
5.d
Explanation:
1. Forests ecosystem have high biodiversity
3.Habitat loss from exploitation of resources, agricultural conversion, and urbanization is the largest factor contributing to the loss of biodiversity. The consequent fragmentation of habitat results in small isolated patches of land that cannot maintain populations of species into the future.
4.It is currently the biggest cause of current extinctions. Deforestation has killed off more species than we can count.
5. Im not sure.
It may be ans c. As Trees absorb toxic chemicals through their stomata, or 'pores', effectively filtering chemicals from the air.

A skateboarder drops in off the top of one side of the half pipe shown below. She does not push off and starts from rest. She stands straight as she skates down one side and up the other. She expected to get to the top of other side but didn’t make it. The skateboarder recalled the law of conservation of energy from science and didn’t understand why she didn’t make it to the top of the other side.
Which of the following actions would help the skater reach the top of the other side of the half pipe?
Lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.
Hold a weight in order to increase her mass and cause the skateboard to move with a greater velocity down the half pipe.
Sit on the skateboard in order to lower her center of mass and increase the potential energy of the skateboard.
Push off at the bottom of the half pipe in order to replace lost energy and add kinetic energy to the skateboard.
The actions that will help the skater reach the top of the other side of the half pipe is to lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.
The law of conservation of energy from science states that energy can neither be created nor destroyed but can be transformed from one form to another.
The skateboarder couldn't make it to the top of one side of the half pipe because the kinetic energy that was generated was converted to heat energy through friction.
As the heat energy is lost to the surrounding environment, the skateboard loses velocity.
Bending down by the skateboarder will provide additional energy to make up for the lost energy.
Therefore, in order for the skateboarder to reach the top of the other side of the half pipe, she has to lubricate the wheels in order to reduce frictional force that is causing her to lose velocity and bend down while skating off the side and bottom of the half pipe.

Answer:
Lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.
Explanation:
Got the answer right on a quiz and reducing frictional force leads to many other contributing factors that makes the skateboarder reach the other side of the half pipe.

The measurable factors are A) How often a plant is watered, B) How much sunlight a plant receives, D) The actual number of new leaves on a plant.
Options (A) (B) & (D) are correct.
Measurable factors are those that can be quantified or expressed numerically. A) The frequency of watering can be counted and tracked over time. B) Sunlight can be measured in terms of intensity, duration, or light levels. C) "Seeing pretty leaves" is subjective and not quantifiable.
D) The actual number of new leaves is a concrete count, making it measurable. When studying or managing plants, it's essential to focus on quantifiable aspects, like watering frequency, sunlight exposure, and counts of observable changes, for accurate analysis and decision-making.

A DNA segment is changed from AATTAG to AAATAG. What type of mutation is this and what is its effect on the genetic variation of a population?
A.
The mutation is a substitution which causes a decrease in the genetic variation of a population.
B.
The mutation is an insertion which causes a decrease in the genetic variation of a population.
C.
The mutation is an insertion which causes an increase in the genetic variation of a population.
D.
The mutation is a substitution which causes an increase in genetic variation of a population.
The mutation from AATTAG to AAATAG is a substitution which causes an increase in genetic variation of a population.
MUTATION:
Mutation refers to any change in the nucleotide sequence of DNA molecule. Mutation can be of different types depending on how it occurs. A substitution mutation is that in which one or more nucleotide base is replaced by another in the sequence. In this question, an original sequence of DNA is given as AATTAG. It was mutated to AAATAG via the replacement of 'T' with 'A'. This means that it is a substitution mutation. However, this mutation will cause an increase in the genetic variation i.e. difference in a population.Learn more at: https://brainly.com/question/21220597?referrer=searchResults

if your leg was to get cut off where would you feel the pain?
The thigh area will feel much more pain as when leg is cut off , all nerves are together in thighs, so more pain will be there.
Hope it helps you... pls mark brainliest if it helped you
Answer:
The nerve(s) in your leg.
Explanation:
It's not your leg that will hurt but the nerve in your leg. So wherever the leg is cut, the nerves will have to be cut as well, but also after one of your limbs is amputated, you may feel like the limb is still there. That's called phantom sensation. You might feel pain in your limb even though it is physically not there.

por que un globo con aire se agranda al sol y se achica en la heladera
Answer: El globo congelado se contrajo porque la energía cinética promedio de las moléculas de gas en un globo disminuye cuando la temperatura disminuye. Esto hace que las moléculas se muevan más lentamente y tengan colisiones menos frecuentes y más débiles con la pared interior del globo, lo que hace que el globo se encoja un poco.
