Answer:
The Cardiovascular System
Explanation:
The respiratory system draws air into the lungs. Oxygen diffuses through the walls of the alveoli and across the walls of the capillaries where it enteres the bloodstream. The oxygen molecules are picked up by red blood cells, which are pumped through the blood vessels by the action of the heart. As the red blood cells carrying oxygen pass through capillaries near the cells, oxygen diffuses into the cells.
Description of thigmotropism is given below.
Explanation:
1. Thigmotropism is a plant’s response to touch.It is a plant’s response to an external stimulus.It can occur quickly or slowly.Thigmotropism may involve the closing and opening of plant leaves.
2. Thigmonasty or thigmotropism can be define as the response of touch shown by the plants. Here, touch is the external stimulus. It can be define as the movement of the plant parts in response to the external stimulus that is contact or touch. It is also known as Haptotropism. The plant may change it's orientation, shape and size of the plant parts.
3,The thigmotropism can be positive or negative depending upon the visual response shown by the plants. The response shown by the plants is generally fast but may be slow. This response is shown by the plants in cases of danger of herbivory.Some plants like Mimosa pudica or touch me not plant shows thigmotropism by closing their leaves on touch
Solution A have more hydrogen ions as pH level 2 indicates that it is highly acidic which means presence of H+ ions. On the other side sol B with ph10 has more OH- ions in it making it base in nature.
The correct answer is A. neither electrons or axons.
An axon is a long, slender nerve fiber of a neuron. Its function is to conducts nerve impulses away from the cell body of a neuron to the dendrite of other neuron. A nerve impulse is an electric signals. A nerve impulse is due to the movement of ions in and out of the cell. It does not allows electrons or other axons to move across the axons. Thus, electrons and axons do not move across the axons.
Answer:
Dermis
Explanation:
The hair follicles are present in the dermal papillae of the dermis layer. The dermal papillae are a series of triangular-shaped cells. The hair follicles are extending from the skin surface to the dermis layer of the skin. The hairs are the extension of the epidermis layer into the dermis layer of the muscle. The hair follicle has 2 parts, such as - the part which extends outside of the epidermis known as the shaft. The base of the follicle known as root. The hair follicle itself has different parts - outer root sheath, inner root sheath, and a centrally placed hair shaft. The erector muscles help in goosebumps of hair during cold.
