Answer:

An increase in capillaries helps to increase healing by improving blood flow to the site of injury. Improving blood flow provides muscles with an increase in oxygen that gives muscle energy and so reduces muscle fatigue and weakness. An improvement in blood flow also supplies muscles with an increase in nutrients.

Diffusion, the most widely-used mechanism, allows the flow of small molecules across capillaries such as glucose and oxygen from the blood into the tissues and carbon dioxide from the tissue into the blood.

What is one advantage that proteins derived from beans have over proteins derived from red meats?
Aleksandr [31]
Answer below———please mark me brainliest It would have to be B

“Proteins derived from beans have less saturated fat than proteins derived from red meats”

It is not always easier to cook beans vs red meats as you would have to boil all day so it’s not A

Saturated fat is the bad fat and beans definitely doesn’t have more than red meats does so it’s not C.

Finally D, they are both proteins which has amino acids so it doesn’t make logical sense.

So therefore it’s B...Hope this helps!

Pertussis is recognized for stubborn, violent coughing which often makes it difficult to breathe.

Anna’s fetal scans showed some abnormality. Which of the following procedure can help her know more about the abnormality?
UNO [17]
B. Amniocentesis. During this procedure, a long syringe is carefully inserted through the woman's stomach into the amniotic sac and withdraws some amniotic fluid. Various tests can be run on this fluid to determine what abnormalities the baby may have. The rest of the terms are rather important to know anyway so I will define them for you.

A pap smear is done on any woman annually to screen for cervical cancer.

A colonoscopy is done on people over 50 typically (and every 10 years after is normal) to screen for colon cancer and polyps, among other things.

Cesarean surgery is a C-section, which is a surgery to extract a baby if natural child birth is too risky and/or the baby is in distress. Basically, it's an emergency surgery for when the baby needs to come out NOW for both the safety of baby and mom.

An endometrial biopsy is when a doctor takes a small sample of the endometrium lining (uterus) and looks at it under a microscope to detect any abnormalities.

kap26 [50]

Answer:

A conditioned stimulus from one learning trial is used in place of an unconditioned stimulus in a new conditioning trial, where it is paired with a second stimulus. The second stimulus then comes to elicit the conditioned response, even though it has never been directly paired with the unconditioned stimulus. This is a description of a procedure called: <em>Higher Order Conditioning</em>.

Explanation:

This is a type of conditioning developed by Ivan Pavlov in the 19th Century during physiological investigations. The results of these studies have shown that the conditioning happens when pairing a stimulus to something that has been condition priorly to produce a response rather than to something that would produce a response naturally.

Pavlov experimented with dogs using bells and objets.

Bells represented a <u><em>conditioned stimulus</em></u>, while objets represented a <u><em>neutral stimulus</em></u> (this is because in a prior experiment called <em>Classical Conditioning</em><em> </em>he had already used bells and the dogs had already been able to recognize bells as a stimulus before.)

In this type of conditioning, Pavlov used a steak and a bell instead of using a random object. When he showed the steak to the dogs, as it was naturally expected, they salivated. Then he resolved to experiment by ringing a bell at the same time he was showing the steak to the dogs, wondering if when the bell rang at the view of the steak the dogs would still salivate, which was exactly what happened. At that moment he realized he had created a conditioned stimulus on his experiments through the use of bells.

Later on, when experimenting through the effects of the <em>Higher Order Conditioning</em>, Pavlov found out that when the bell (conditioned stimulus) was rang (which was the way in which he ordered the dogs to stop salivating) and he decided to introduce a random object (neutral stimulus), the dogs  still continued to salivate, and even if he took the bell away and the random object was used instead of the bell, the dogs would still continue to salivate. Upon this facts, Pavlov discovered that even if the stimulus was changed, salivation would still happen.

I hope it helps!
