Answer:
A) stratum basale.
Explanation:
The epidermal layer consists of five layers. This is not having any blood vessels and known as avascular. The four-layer starting from stratum basale to stratum corneum is referred to as thin skin. But the skins of foot and palm has another layer called stratum lucidum. This layer forms the five layers of the epidermis.
The stratum basale is the deep layer of the epidermis. Below this layer dermis is present. This layer consists of basal cells which are precursors of keratinocyte cells. The stratum basale is a single layer cell and it undergoes continual mitosis. So that this cell produces new cells and these new cells replace the other older cells above it.
As the basal cells are precursors of keratinocytes, they produce all keratinocytes of the epidermis.
Two other types of cells are produced from this layer - Merkel cell, and melanocyte. Merkel cells act as touch receptors and melanocytes produce melanin pigments.
that they are not soluble with water
Answer:
The correct answer is Circulatory system.
Explanation:
Circulatory system is also known as the cardiovascular system which is used to circulate the blood around the body of most of the animals. It mainly consists of a heart that is used to pump the blood and different blood vessel that are used for the transportation of blood to different parts of the body.
The main functions plays by circulatory system are:
1. It provides oxygen to different organs of the body through blood.
2. It helps in providing nutrients, hormones to different organs and remove waste products from cells.
3. It helps in locating the immune cells to the injury site which helps the body to fight the infection.
ATP molecule functions as the power source for a cell. Sometimes it is compared to a battery, which is a pretty fair analogy, but it is more mobile and flexible in its functions than a battery is.
