Briefly Describe How T Cells And B Cells Respond To Pathogens

Answers

Answer 1

Answer:

Helper T-cells stimulate B-cells to make antibodies and help killer cells develop. Killer T-cells directly kill cells that have already been infected by a foreign invader. T-cells also use cytokines as messenger molecules to send chemical instructions to the rest of the immune system to ramp up its response.

Answer 2

Answer:

B cells produce antibodies, which bind to antigens and either block viruses and bacteria from entering cells (neutralizing antibodies) or trigger additional immune defenses. The two main types of T cells are CD4 and CD8 cells. CD4, or helper, T cells coordinate the immune response. These are the primary targets of HIV.

i need thw answer for Which is a long-term effect of sun exposure?

ASAP

Answers

Skin cancer, deep lines or wrinkles as you get older. You can’t turn back the damage that the sun’s effects have on your skin. Use sunscreen now to protect your skin from sun damage as you age.

Skin damage, especially wrinkles and accelerated aging, is one of the long-term effects of sun exposure.

The skin's collagen and elastin fibers, which give it strength and flexibility, can break down as a result of prolonged and repeated exposure to the sun's ultraviolet (UV) radiation. Fine lines, wrinkles and age spots develop as a result of the skin losing its firmness and elasticity.

Additionally, melanoma, the most serious form of skin cancer, is more likely to develop as a result of prolonged sun exposure. Therefore, avoiding prolonged sun exposure and maintaining healthy skin can be accomplished by taking precautions such as sunscreen, wearing protective clothing, and seeking shade.

Ok so is it possibly to have ptsd from a dream. I've been wondering this for a while because i had a strange dream but like all my family died in it but the whole time it smelled like pure milk chocolate which was very strange but now when i smell chocolate I start to tear up and have flashbacks to that dream.

Answers

Maybe you should find a consultant.Remind your self that it was just a dream.dreams are basically made up brain stories that the mind creates They can make you feel happy, sad, or scared. they may seem confusing or perfectly rational.Usually people forget dreams but you get flashbacks this is sign of anxiety!! It is important that you remind yourself that you are safe and that you are not reliving the trauma, no matter how bad it feels. After the flashback is over, try to understand it. Perhaps write it down or talk about it with a trusted friend or a counsellor.
Also just know you are not going crazy, There are some things you can do that can help you manage these reminders of the trauma.I am assuming you are stressed so consider doing (Deep breathing exercises, Meditation, Relaxation to music, Counseling, to help you recognize and release stress,and Sleep Enough) these practices will decrease stress and anxiety . ^-^

A man carried a handgun for protection, but failed to register it. In the applicable jurisdiction, possession of an unregistered handgun is a felony. The man had little experience with firearms, and negligently carried the gun in a holster designed to fit a different handgun model. While the man was shopping for groceries one day, the gun slipped out of the holster, fell to the floor, and accidentally discharged. The bullet struck a fellow shopper, who died as a result of the incident. The crimes below are listed in descending order of seriousness. Which is the most serious homicide crime for which the man can be convicted?
A. Felony murder
B. Voluntary manslaughter
C. Involuntary manslaughter
D. No crime

Answers

Answer: C. Involuntary manslaughter

Explanation:

This is involuntary manslaughter because the man was negligent in the action that led to the death of the shopper. In other words, he did not mean to do it and it happened only because he wasn't careful.

This rules out murder because a killing has to be intentional to be ruled as murder. It also rules out voluntary manslaughter because the man did not mean to kill the shopper by his actions.

"Healthy environment supports healthy and happy life." Justify it

Answers

Answer:

I think a healthy atmosphere promotes a happy existence. What makes us joyful varies from individual to another. Whatever we are exposed to, we usually discover what makes us happy. Most people tend to desire what they lack. We all make decisions that are difficult to reverse if we don't like the consequence. Then there are events beyond our control, both good and bad. I believe that when something uncontrollable happens to a person, they can feel discouraged and either give up on achieving happiness or take a long time to find the energy to start again.

In what method for reducing stress does a health professional measure tension in the body’s muscles in response to certain stressors

Answers

The physiological method used by health professionals to evaluate tensions in specific muscle groups, and then relax them is the progressive muscle relaxation (PMR).

Progressive muscle relaxation (PMR) is a relaxation therapy that is used to obtain relief from stressors, especially useful for the reduction of muscle tone.  

This method has three phases:

The first phase is called Voltage Relaxation. It involves the tension and then relax different muscle groups throughout the body, to learn to recognize the difference between a state of muscle tension and a state of muscle relaxation.

The second phase consists of mentally reviewing muscle groups, verifying that they have relaxed to the maximum.

The third phase is called mental relaxation. This phase consists of thinking about a positive scene or keeping the mind blank. It is about relaxing the mind while the person continues to relax all his/her body.

Therefore, we can say that progressive muscle relaxation is a method that favors deep relaxation with little effort, helping to measure muscle tension and reducing stress.

According to Newton's third law of physics, who would have strong muscles: a long-distance runner or a runner who jumps hurdles?

Answers

Answer:

A runner who jumps huddles.

Explanation:

As he jumps a huddle, the feet exert a greater force from the ground. And as it lands on the ground, the feet put more force on ground.

This action and reaction is equal

[tex]{ \sf{.}}[/tex]

According to Newton's third law of physics, a runner who jumps hurdles would have strong muscles.

What is Newton's third law of motion?

Newton's third law implies that in nature, for every action (force), there is an equal as well as opposite reaction.

When object A applies a force to object B, object B applies an equal and opposite force to object A. In other words, forces are the result of interactions.

Newton's third law can be used to determine which forces are external to a system.

Identifying external forces is critical when creating a problem because the external forces must be added together to determine the net force.

The feet exert more force from the ground as he jumps a huddle. And as it lands, the feet exert more force on the ground. This action and reaction are identical.

Thus, the runner who jumps hurdles will have strong muscles.
