<span>There are four different types of skeletal muscle contractions: 1. Concentric (isotonic) contractions: In this contraction type, the muscle actively shortening. The raising of a dumbbell during biceps curl exercise is an example of concentric contractions. 2. Eccentric Contractions: During normal daily activity our muscles are often active while they are lengthening. Walking is an example of eccentric contractions. 3. Isometric Contractions: The muscle is activated at a fixed length. Holding an object would be an example of this type of contractions. 4. Passive Stretch: The muscle is being lengthened during in a passive state. An example of this type is the pull one feels in their hamstrings while touching their toes.</span>

There are 3 kinds of contraction in skeletal muscle:
Concentric contraction: The muscle in this contraction will gives force more than the load gives. This will make the muscle shorten as it pulling the load.

Eccentric contraction: In this contraction, the force given by muscle is not enough to pull the load. This causes the load pulling the muscle instead. So the muscle will be lengthened as the load moving away.

Isometric contraction: In this contraction, the length of the muscle will be kept same by adjusting the force given to be equal to the force needed.

What type of chromosomal abnormality can lead to multiple copies of a gene, some of which can incur mutations that can lead to t

koban [17]

A trisomy is a chromosomal condition characterized by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46.

Trisomy means the presence of an extra chromosome in some or all of the body's cells. This results in a total of three copies of that chromosome instead of the normal two copies. For example, Down syndrome (trisomy 21) is caused by having three copies of chromosome 21 instead of the usual two copies.

This genetic condition is the result of a genetic mutation where your cells don't divide as they should. You can't prevent this abnormality from happening during cell division.

Anna007 [38]

Answer:

oxygen

Explanation:

Without oxygen aerobic respiration cannot occur. Therefore ATP is produces by anaerobic reparation which is from glycolysis only. Lactate/ lactic acid is formed when glycolysis is the only production of ATP.
