Answer: The cellular process that enables the cells to grow and develop into tissue is called MITOSIS.

Explanation:

The skin is the largest organ of the body that contains various cells which includes: the epidermal and dermal cells. With the various activities of man, the skin is susceptible to injury through burns.

The healing of the skin, especially injury sustained from burns involves the interaction between the different cell types. Recently, scientists can bioengineer skin in a laboratory to treat severe burns and other types of skin injuries which are grown from living cells.

MITOSIS is the cellular process that enables the cells to grow and develop into tissue. It is also defined as the process by which a cell duplicates into two genetically identical daughter cells.

The process of mitosis occurs in 4 stages; the prophase, metaphase, anaphase, and telophase. The various activities that occurs on these stages brings about the growth and the development of the cells into tissue.

What gas is a reactant in cellular respiration
pochemuha

Answer:

Explanation: Although cellular respiration has multiple parts, the basic chemical equation is:

Answer: Oxygen

Explanation: Oxygen + Glucose (sugar) = Carbon Dioxide + Water + Energy (ATP)

This equation is often broken into two parts, the reactants and the products. Reactants are the molecules that begin cellular respiration, in this case that would be oxygen and glucose. Products are what forms during cellular respiration. Here, the products are carbon dioxide, water, and energy. As the focus of this lesson is on the reactants of cellular respiration, oxygen and glucose, let's take a look at those.

Reactants--

The first reactant in the equation for cellular respiration is oxygen. Most people are familiar with oxygen since it's the primary gas needed for sustaining our lives. We obtain oxygen by simply breathing. Oxygen is highly reactive and therefore perfectly suited for driving chemical reactions such as cellular respiration. However, people may be less familiar with the second reactant in our respiration equation: glucose.
