4. Compare and contrast the rate of sea floor spreading along the Mid-Atlantic Ridge and East
Pacific Rise.

Answers

Answer 1

Answer:

The Mid-Atlantic Ridge runs down the center of the Atlantic Ocean. ... The rift valley is 1 to 3 km deep, about the depth and width of the Grand Canyon. In contrast, the East Pacific Rise spreads fast at rates of 6 to 16 cm per year (more than 20 cm per year in the past).

W Within a forest ecosystem, there is a large amount of diversity among members of a warbler species. Of the following stages of meiosis illustrated for a typical cell, which contributes most to diversity among the warblers? Pay special attention to the chromatids.​

Answers

Answer:

Explanation:

How a Forest Ecosystem Matures . Forest ecosystems tend to always be moving toward maturity or into what foresters call a climax forest. This maturing, also called forest succession, of the ecosystem increases diversity up to the point of old age where the system slowly collapses. One forestry example of this is the growth of trees and the entire system moving toward an old growth forest.

A Large amount of warbler species, crossing over between homologous chromosomes, is closely involved in genetic variation. The stage that most contributes to diversity is stage C, where you can see chromosomes after crossing-over.

There are different mechanisms involved in producing genetic variation among descendants, are-

Crossing-over between homologous chromosomes (prophase 1), The Random lining of homologous chromosomes (metaphase 1),

Random fertilization

The Crossing-over events occur between two homologous chromosomes within the equatorial plane and make the daughter cells genetically different from the first one.

The Chiasma is the position where two homologous chromatids interchange genetic information, giving an area for brand spanking new genetic material or information to be provided to descendants.

After crossover, homologous chromosomes get separated again. In the attached image there are four different stages of meiosis.

Stage C is the one that contributes foremost to diversity. We can see that crossover has already occurred between homologous chromosomes and that they have already interchanged segments.

In the image, you will see the difference between chromosomes that have gone through the crossing over mechanism, and chromosomes that have not. The difference in color represents segments interchange and variation.

Therefore, that answer shows the contribution to diversity among the warblers.

Think and discuss:Suppose you are a farmer trying to grow plants in a greenhouse. Why would it be important to know what the limiting factor is

Answers

Answer:

Because limiting factors affect plant growth

Explanation:

A limiting factor is a condition that limits the population's growth in an ecosystem by slowing or stopping its growth. These factors are generated by the lack or excess of a particular resource. In plants, limiting factors include, among others, light, water, temperature, oxygen, food, (i.e., nutrients and minerals), space, etc. In this case, the farmer must know which greenhouse conditions are limiting factors in order to ensure the survival and optimal development of the plant population.

Which is not a function of the respiratory system? *
It warms air entering the body.
O It exchanges oxygen and carbon dioxide.
O It pumps blood to the organs.
O It creates sound through the voice box.

Answers

Answer:

it exchanges oxygen and carbon dioxide

Explanation:

You inhale oxygen and exhale carbon dioxide

Out of the given options 3 that is "it pumps blood to the organs" is not a function of the respiratory systems.

The respiratory system is a network of organs and tissues that assist you in breathing. This system assists your body in absorbing oxygen from the air so that your organs can function.

It also removes waste gases from your blood, such as carbon dioxide. Allergies, illnesses, and infections are common difficulties.

The respiratory system contributes to the warming and humidification of the air we breathe. The air is warmed as it goes through the nasal passages and pharynx, which helps to protect the lungs' sensitive tissues.

The respiratory system contributes to the production of sound. When air flows through the larynx (voice box), the vocal cords vibrate, producing sound.

Thus, the option 3 is not the function of the respiratory system.

Alana summarized what happens when a ball sitting on top of a grassy hill rolls down the hill.

The motionless ball has potential energy. Once the ball starts to roll down the hill, new kinetic energy is made. As the ball rolls across the grass, it slows down. The kinetic energy of the ball is converted to other forms of energy.

Which best describes Alana’s error?

The motionless ball does not have energy because it is still.
Kinetic energy is not made; it is a result of energy transformation.
The ball cannot slow down unless someone touches it.
The energy is not converted; it disappears.

Answers

Answer:

It's actually B that guy is wrong on Edge.

Explanation:

Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.

What are the various types of energy?

The law of conservation of energy says that energy is neither created nor destroyed but only converted from one form to another, such as from the kinetic to the potential and vice versa. Here, the ball is placed at the top, where it has no motion, but the ball has potential energy, and that potential energy gets converted into kinetic energy when the ball starts to roll down the hill. After sometime, the ball spontaneously stopped on the ground, and the kinetic energy was converted into potential energy.

Hence, Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.

How does a stem cell become specialized into a heart cell?

Answers

Answer:

Explanation:

stem cells are manipulated to specialize into specific types of cells, such as heart muscle cells, blood cells or nerve cells. The specialized cells can then be implanted into a person. For example, if the person has heart disease, the cells could be injected into the heart muscle.

Daughter cells are created when stem cells divide properly in the body or a lab to create more cells. These daughter cells either develop into fresh stem cells or into differentiated cells with a more specific role, such as bone, blood, brain, or heart muscle cells.

How are stem cells differentiated?

According to research, cardiomyocytes made from pluripotent stem cells can develop into beating human heart muscle cells that both produce the required signals and restore muscle lost during a heart attack.

Stem cells have the ability to multiply and develop into a variety of relatively mature cells. When inserted into a blastocyst, embryonic stem cells have the ability to develop into any organ in the human body.

Therefore, theoretically, every organ in the body might be replaced using embryonic stem cells.

Answers

Explanation:

it is systematic desensitization.

Creating a list of anxiety-triggering situations and training in relaxation are important aspects of SYSTEMATIC DESENSITIZATION.

Systematic desensitization is a type of therapy based on the combination of relaxation methods with gradual exposure to the fear (phobia).

The objective of the exposure to the fear is that the patient feels progressively less anxious about his/her phobia.

In consequence, systematic desensitization increases the feeling of self-control and gradually reduces fear.

In conclusion, creating a list of anxiety-triggering situations and training in relaxation are important aspects of SYSTEMATIC DESENSITIZATION.
