A muscle fiber is simply a muscle cell, or the building blocks of muscles. See, like the rest of your body is made up of lots and lots of individual cells, your muscles are also made up of cells.
Muscles are made up of groups of fascicles. When stimulated, they contract to produce motion. No more running, talking, walking and, well,
muscle fiber types and muscular contraction Dark meat is composed primarily of slow fibers, and these slow fibers are more dependent on blood supply and oxygen, whereas light meat is composed of fast fibers, which are less dependent on blood and oxygen.
Hence, the right answer is option 1 " Rapidly move action potentials to the interior of the muscle fiber"

Alexandra [31]

Answer:

True

Explanation:

All the cells in a living organism undergo cellular respiration to extract the chemical energy from food molecules and convert it into usable energy form of ATP.

The food molecules having chemical energy are oxidized to produce energy that can be used for all cellular metabolism processes and other energetic reactions required for life

Later on this ATP's energy is used for building new molecules and transporting materials.

Hence, given statement is true

sclerenchyma

Explanation:

sclerenchyma is a suppprting tissue that gives the plants rigidity and support to make it stand upright. It is made up of scleroids and fibre.

Scleroids are small stonelike materials that are arranged in a way that helps the plants withstand force.

For example when rain falls and the wind's current is strong, it sways the plant from left to right but because of sclerenchyma, the plant can withstand the current and return to its normal position.

Polar bear somatic cells contain 74 total chromosomes. how many chromosomes would a polar bear egg cell contain?

PtichkaEL [24]

Answer:

The correct answer would be 37.

Egg or sperm or gametes are cells produced by the process of meiosis and carry half the number of chromosome (n) present in a parental cell (2n).

Meiosis is a type of cell division which results in the formation of four daughter cells each having exactly half the number of chromosome present in parent cell.

The sperm unite or fertilize with egg which restore the chromosome number (2n) in the zygote.
