Consider what occurs when calcium is present inside a sarcomere. Based on this knowledge,
predict what the result would be If calcium entered a sarcomere, but where UNABLE to leave the
sarcomere.

Answers

Answer 1

Answer:

Since calcium is an ion that allows the contraction of the sarcomere, if the calcium does not leave the sarcomere the muscle contraction is maintained and the sarcomere is unable to relax.

Explanation:

Calcium (Ca²⁺) is necessary for muscle contraction to occur. Once the muscle fiber receives the signal that starts the contraction, cytoplasmic Ca²⁺ levels increase —by intracellular Ca²⁺ release and extracellular Ca²⁺ input—causing muscle contraction.

If for some circumstance the cytoplasmic Ca²⁺ levels do not decrease, muscle contraction would be maintained with no possibility of relaxation. This is a brief summary of the process by which Ca promotes muscle contraction:

Tropomyosin is a molecule that blocks the bond between actin and myosin. Ca²⁺, found in the sarcoplasmic reticulum, exits the sarcoplasm and binds to troponin C, whose interaction with tropomyosin leaves actin and myosin free to bind. Ca²⁺, in a high concentration, promotes the union of the filaments, shortening the muscular fiber and producing the contraction.

The Ca²⁺ pumps of the sarcoplasmic reticulum and the Na⁺/Ca²⁺ exchanger decrease the levels of intracellular Ca, by storing it again in the reticulum or taking it to the extracellular space, respectively.  This decreases intracellular Ca²⁺  concentrations.

If this process does not occur properly, Ca²⁺ levels remain elevated and muscle contraction is maintained, without relaxation occurring.

Answers

Answer:

Social health refers to the ability of a person to have a sufficient number of social relationships (that are functional, of course), live in the society without social strain and to establish accepted social behaviors.

Explanation:

The WHO (World Health Organization) provided a clear picture of what health is truly all about. It is "not only the absence of disease," which means it encompasses more than what most people think of. Part of this is the person's "social health."

For a person to be considered healthy, he should have social relationships that are well-functioning. This means that the person has meaningful relationship with other people. This allows him to develop a sense of concern for others.

The person should also live without social strain. This is the pressure a person receives from the society which leads him to commit wrongdoings or crimes.

The person should also follow social behaviors that are within the norm to be considered healthy. This will allow him to conform and function normally.

A blood cell marker that can help with blood typing can also be called an:

Answers

Answer:

antigen

Explanation:

Categorizing blood according to type helps prevent reactions when someone gets a blood transfusion. Red blood cells have markers on their surface that characterize the cell type. These markers (also called antigens) are proteins and sugars that our bodies use to identify the blood cells as belonging in us.

The two main blood groups are ABO and Rh.

The ABO blood system has four main types:

Type A: This blood type has a marker known as A.

Type B: This blood type has a marker known as B.

Type AB: This blood type has both A and B markers.

Type O: This blood type has neither A or B markers.

Blood is further classified as being either "Rh positive" (meaning it has Rh factor) or "Rh negative" (without Rh factor).

So, there are eight possible blood types:

O negative. This blood type doesn't have A or B markers, and it doesn't have Rh factor.

O positive. This blood type doesn't have A or B markers, but it does have Rh factor. O positive blood is one of the two most common blood types (the other being A positive).

A negative. This blood type has A marker only.

A positive. This blood type has A marker and Rh factor, but not B marker. Along with O positive, it's one of the two most common blood types.

B negative. This blood type has B marker only.

B positive. This blood type has B marker and Rh factor, but not A marker.

AB negative. This blood type has A and B markers, but not Rh factor.

AB positive. This blood type has all three types of markers — A, B, and Rh factor.

Having any of these markers (or none of them) doesn't make a person's blood any healthier or stronger. It's just a genetic difference, like having green eyes instead of blue or straight hair instead of curly.

Most vegetables, like carrots, potatoes, broccoli, cabbage and celery should be stored in a plastic bag or container in the crisper of your fridge. Mushrooms are best stored in a paper bag. Vegetables should be stored in a different part of the fridge than fruit. This will prevent them from ripening too fast. Leafy green vegetables – Greens like lettuce, collards, chard, kale, and spinach should be stored in the refrigerator. Onion family – Store garlic and onions in a cool, dark and dry space but separate from other foods because of their strong odors. Mushrooms – Keep unwashed in the refrigerator.
