Scientific evidence documents the pattern of evolution. The evidence exists in a variety of categories, including direct observa

anzhelika [568]

Answer:

Direct observation of evolutionary change: creation of drug-resistant bacteria.

Fossil record: discovery of transitional forms of animals, discovery of shells of extinct organisms

Homology: similarities in mammalian forelimbs, identical genetic code in fireflies and tobacco plants, vestigial pelvis in right whales

Biogeography: resemblance of endangered island species to neighboring mainland species,

Many species, including some whales and birds, will travel thousands of kilometers during annual migrations. I. Provide one reas

Ivan

Answer:

1- A species can migrate over long distances because they have metabolisms suitable for that, adaptation mechanisms to withstand different adversities. They usually do it to be able to reproduce in ideal climaxes or feed on certain living things or plant species.

2-The existence of oil fields, or oil towers for the manufacture of fuel.

3-Implement electric cars or batteries that do not depend on fuels such as diesel, naphtha.

Explanation:

In this exercise it is good to highlight that during the migration of animals of different species their numbers decreased both to reach the territory to which they migrate and by human intervention in nature in a harmful way.

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.
