Answer:

Adenine

Explanation:

Adenine is a nitrogenous base found in RNA and DNA. it is one of the purine bases and can be paired with thymine and uracil.

Adenine is not only found in nucleic acids (DNA and RNA) it is also part of the adenosine triphosphate, ATP, which is an extremely important molecule because it is the energy currency of the cell being used in various metabolic processes in the body.

notsponge [240]

Answer:

Fatty acids are long chain carboxylic acids, they contain the carboxyl, COOH, functional group. The general formula for a fatty acid is R-COOH where R represents a long hydrocarbon chain. If the hydrocarbon chain, R, contains only single bonds between the carbon atoms, the fatty acid is said to be saturated.

Describe all muscle tissues, including cell shape, layers, intercellular connections,

zmey [24]

<h2>Description of muscle tissues. </h2>

Explanation:

There are three types of muscle tissue are cardiac, smooth, and skeletal.

1. Cardiac muscle tissue: It is located in the walls of the heart.

They appear striated.

Control is involuntary.

Function: To pump blood through the blood vessels in your body.

2. Smooth muscle tissue: It is located in walls of hollow visceral organs, except the heart.

They appear spindle-shaped.

Control is involuntary.

Function: To move food through the digestive tract.

To regulates air flow in lungs.

3. Skeletal muscle tissue: It occur in muscles which are attached to the skeleton.

They appear striated.

Control is voluntary.

Function: To support the body.

It makes bones and other body parts move.

Cell shape : There are different shapes of cells which are as follows:

1. Squamous 2.Cuboidal 3. Columnar 4. Polygonal 5. Stellate

6. Spheroid 7. Discoid 8. Fusiform 9. Fibrous.

Muscular layer: The muscular layer is present in many organs in the vertebrate body.

It is responsible for peristaltic movement in body.

There are two layers of muscle.

1. Inner 2. Outer layer.

Inner layer: The muscle of the inner layer is arranged in circular rings around the tract.

Outer layer: the muscle of the outer layer is arranged longitudinally.

Intercellular connections or junctions: These are the structures which provide adhesion and communication between cells.

There are mainly three types of junctions:

1. Tight junctions: It help to stop substances from leaking across a tissue.

2. Adhering junctions: It perform the function of cementing so as to keep neighbouring cells together.

3. Gap junctions: It facilitate the cells to communicate with each other by connecting the cytoplasm of adjoining cells, for rapid transfer of ions, small molecules and sometimes big molecules.

Meals provided by congregate or home-delivered meal programs are designed to provide ______ of the RDA or AI for nutrients.

Delicious77 [7]

Answer:

One - third.

Explanation:

The children and adults must be protected from the malnutrition and each individual has the right to attain the minimum nutrient requirement. Different programs run in U.S.A. to fulfill the nutrient deficiency.

RDA (Recommended Dietary Allowance) is a type of allowance given to the individual for the average daily intake to meet the nutrient requirement. Adequate Intake (AI) is provided when the individual do not have proper proves to develop RDA. The home delivered meals provide atleast one-third of the RDA.

Thus, the answer is one-third.
