Answer: Free nerve endings

Explanation:

A free nerve ending can be defined as the bare nerve endings that are unspecialized afferent nerve fibers which sends its signal to sensory neuron.

The main function of these nerve endings is to being the signals to the brain from the periphery of the body. They can sense itch, hair movement, temperature, pain et cetera.

The free nerve endings can detect pain, temperature, itch and hair movement. Merkel's disks can detect pressure, position and static touch features. Pacinian corpuscles are sensitive to vibration while Meissner's corpuscles are sensitive to light and touch.

Pea contains only 0.25% phenylethyl alcohol because high concentrations inhibit both gram-positive and gram-negative organisms.

sdas [7]

If the alcohol concentration in PEA agar was increased, it would inhibit both Gram - and Gram + bacteria by breaking down membrane absorbency barrier, tolerating influx of substances that are generally blocked and leakage of cellular potassium. High alcohol concentrations would lead to disruption or halting of DNA synthesis in both Gram + and Gram - bacteria

A diploid somatic ("body") cell has 2n=20 chromosomes. At the end of mitosis, each daughter cell would have ______ chromosomes.

Nostrana [21]

Answer:

1. 20 chromosomes

2. 10 chromosomes

3. 10 chromosomes

Explanation:

1. The process of mitosis results in the two daughter cells from the same parental cell with exactly the same genetic material. Thus the two cells contain the same number of chromosomes as the parent cell. Therefore if a cell with 20 chromosomes undergoes mitosis will result in the 20 chromosomes.

2. During meiosis I two daughter cells are formed with different ploidy levels as the number of the chromosome reduces to half. Therefore the cell with 20 chromosomes results in two cells with 10 chromosomes.

3. During meiosis II, the two daughter cells formed from meiosis I result in the formation of two more daughter cells with an exact number of chromosome number that is 10 chromosomes.

zimovet [89]

Answer:

Option 4 - Calcium

Explanation:

The divalent cation called calcium is needed to provide additional support to the bone matrix.

Calcium is considered one of the most important components in bone development. It helps in the formation as well as maintenance of bone. During the modeling and remodeling process of bones, calcium facilitates the formation of semi-hard new tissues which leads to the formation of new bone which is very hard.

Due to this reason, calcium is needed to create extra bone matrix support.
