Do you think geothermal energy is a renewable resource? Why or why not? What are the benefits of using this energy to power home

Keith_Richards [23]

Geothermal is a renewable energy, because it is from the heat produced by the earth. The earth gets heat from the sun, which will be there for the next million of years. Geothermal has benefits, because if we harness the use of it, instead of mining out all of our coal and oil, we can use this for a long run, and only leave non-renewable energy resources for backup. However, there are consequences to communities and surroundings. The geothermal only benefits when the earth is warm. When the earth becomes too warm, we wouldn't even need the energy anymore cuz everythings dead. So we can use this, but overall we must try to lower the amount of resources that produce this thing as possible.. ( use other renewable energy)

hope this helps

List the order of the reactions to metabolize glucose?

FromTheMoon [43]

The metabolism of glucose involves the breakdown of glucose molecules to form the needed energy by the cell called ATP.The process follows the order of;

1.Glycolysis

2.Citric acid cycle

3.Oxidatize phosphorylation.

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.

Based on this tree, which statement is correct? A phylogenetic tree of the living organisms. The main branch divides into two br

alexgriva [62]

Answer:

a) Salamanders are a sister group to the group containing lizards, goats, and humans.

Explanation:

A phylogenetic tree is a diagram that represents the evolutive relations between organisms. As you can see in the attached image, the branch that contains salamanders and the group containing lizards, goats and humans, come from the same point as they are in the group 2a and 2b, because of this Salamanders are a sister group to the group containing lizards, goats, and humans.

b) Goats are in the same level as humans because they come from the same point, so they are more close between them than with salamanders.

c) Lizards are more closely related to salamanders than humans, because humans are in an upper branch, then is not true that salamanders are closely related to lizards as to humans.

d) A basal taxon is a lineage that evolved early, so it separates from the tree in an early stage, as it happens to the salamanders that separated early but not humans.

Then the correct answer is a)

Salamanders are a sister group to the group containing lizards, goats, and humans.
