Answer:

The intense and constant activity of insulin synthesis explains why pancreatic beta cells possess more rough endoplasmic reticulum and ribosomes than other cells.

Explanation:

Both ribosomes and the rough endoplasmic reticulum are necessary for protein synthesis to occur. In cells whose function is to produce substances, such as glands, the content of these cellular structures is higher in order to fulfill their function.

The pancreatic beta cells, located in the islets of Langerhans, have the function of synthesizing insulin, an endocrine hormone in charge of regulating the glucose content in the blood. Because the beta cells constantly produce insulin, their content of rugged endoplasmic reticulum and ribosomes is high, in order to satisfy the demand for this hormone in the body.

A producer cannot make sugars in the absence of light, the correct option is A.

<h3>What are producers?</h3>

Producers, also known as autotrophs, are lifeforms that produce their own food.

They obtain energy from chemicals or the sun and transform it into usable energy in the form of sugar or food using water.

Plants and algae can produce their own food by harnessing solar energy. These organisms are referred to as producers because they generate their own food.

Thus, the correct option is A.

During replication, which sequence of nucleotides would bond with the DNA sequence ATCAG?

andrew11 [14]

Answer:

TAGTC

Explanation:

There are four different nucleotides in DNA: adenine, thymine, cytosine and guanine.

The bases pair like so:

A with T (adenine with thymine)

C with G (cytosine with guanine)

The DNA sequence given is :

ATCAG

Match As with Ts, Ts with As, Cs with Gs and Gs with Cs.

The sequence of nucleotides that would bond with the sequence above is:

TAGTC

Answer:

Ribose

Explanation:

DNA is a large molecule, a type of nucleic acid which store and act as a genetic material of the cell. DNA molecule is formed by the repeating monomer units called nucleotides.

Each nucleotide is made up of three subunits as:

1. 5-C sugar: De-oxyribose formed by the removal of oxygen group from 2' OH group of ribose. Ribose is the sugar molecule present in RNA nucleic acid.

2. Phosphate group (PO₄³⁻)

3. Nitrogenous bases: adenine, guanine, adenine and cytosine.

Thus, ribose is the correct answer.

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.
