You are in charge of genetically engineering a new organism that will derive all of its ATP from sunlight by photosynthesis. Will you put the enzymes of the citric acid cycle in this organism

Answers

Answer:

Yes.

Explanation:

I will put the enzymes of the citric acid cycle in this organism so that in the absence of sunlight, it also produces energy to grow quickly. Citric acid cycle is a series of chemical reactions which release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. This cycle is also called Krebs cycle so incorporation of this cycle is good for the organism.

A. The production of dirt.B. The release of free nitrogen into the atmosphere.C. The release of sulfur dioxide into the atmosphere.D. The movement of air currents by convection cells.

The production of dirt is cause predominantly by living organisms

This production can be caused through emission of pollution in the form of air, water, soil, noise or e-waste.

What is Pollution?

Pollution is defined as the introduction of unwanted harmful elements in the form of release of gaseous toxic substances which result into polluting the environment.

These pollutants can be both natural and anthropogenic.

Natural pollutants are volcanic ash, river sediments

Anthropogenic pollutants are chemicals released from industries vehicular emission.

Majorly pollution are of four types- Air, Water, Soil and Noise. Recently another pollution in the form of e-waste is also prominent.

Effects of pollution on environment:

1. Biomagnification describes situations where toxins (such as heavy metals)  passes through trophic levels, becoming exponentially more concentrated in the process.

2. Carbon dioxide emissions cause ocean acidification, the ongoing decrease in the pH of the Earth's oceans as CO2 becomes dissolved.

3. The emission of greenhouse gases leads to global warming which affects ecosystems in many ways.

4. Nitrogen oxides are removed from the air by rain and affect the land which can change the species composition of ecosystems.

5. Smog and haze can reduce the amount of sunlight received by plants to carry out photosynthesis and leads to the production of tropospheric ozone which damages plants.

6. Sulfur dioxide and nitrogen oxides can cause acid rain which lowers the pH value of soil.

7. Organic pollution of watercourses can deplete oxygen levels and reduce species diversity.

Rest three options are majorly natural process.

Option B focuses on release of free nitrogen into atmosphere which is one of the important step of Nitrogen Cycle.

Option C focuses towards release of Sulfur Dioxide into atmosphere. This process is caused either naturally or anthropogenically. Thus cant blame solely the anthropogenic factor for its release.

Option C is the total natural process i.e. Climatological Process where air currents are regulated by Convection Cells and regulate based on different natural factors.

The term voltage describes the:
-electrical potential difference between two points.
-likelihood that an electrochemical gradient will develop.
-process of molecules moving from an area of high concentration to low
concentration.
-way in which osmosis determines water movement.

Answers

Answer:

electrical potential difference between two points.

Explanation

Voltage refers to the electrical potential difference between two distinct points. It doesn’t describe the way in which osmosis determines water movement (osmotic pressure), nor does it describe the process of molecules moving from an area of high concentration to low concentration (diffusion), or the likelihood that an electrochemical gradient will develop.

The term voltage describes the electrical potential difference between two points. Option A is correct.

Voltage is a measure of the amount of energy that is available to move electrons from one point to another. It is measured in volts (V). The higher the voltage, the more energy is available to move electrons.

The electrical potential difference between two points is created by the difference in the number of electrons at those two points. If there are more electrons at one point than at another, there will be a voltage difference between the two points. This voltage difference will cause electrons to flow from the point with more electrons to the point with fewer electrons. Option A is correct.

1. Describe the purpose of mitosis.
2. Describe what is happening in each stage and what each stage looks like:
Prophase
Prometaphase
Metaphase
Anaphase
Telophase
Cytokinesis

Answers

Answer:

1) The purpose of mitosis is growth and repair of cells

Explanation:

Prophase:

-DNA condenses (supercoiled, chromatids are visible under light microscope);

-Nuclear membrane begins to disintegrate (by the end of prophase  it is completely gone)

-Centrioles move to opposite ends of the cell

-Splinde fibers start to form from the centrioles and grow

Metaphase:

-Spindle fibers, departing from both poles, are attached to each centromere, on opposite sides

-The spindle fibers pull the chromosomes back and forth until they align in a plane along the equator of the cell, which is called the equatorial plane

Anaphase:

-The spindle fibers shorten

-The centromeres of sister chromatids split

-Chromatids move apart, pulled by the spindle fibers

-Chromatids become chromosomes

-Half of the chromosomes move to one cell pole, half to the other

Telophase:

-The chromosomes reach the cell pole

-Nuclear membrane reforms

-Spindle fibers break down and disappear

-The chromosomes begin to uncoil, which makes them diffuse and less compact

Cytokinesis:

-The cell membrane pinches inward until the cell divides in two;

-There are two daughter cells with the same structures and number of chromosomes as the parent cell

-Chromosomes decondense

Please use the following information to answer the questions below. The southern grasshopper mouse feeds regularly on the Arizona bark scorpion, the most venomous scorpion in the United States. While attempting to capture the scorpion, the mouse usually gets stung multiple times by the scorpion but does not seem to be affected. While attempting to capture the scorpion, the mouse's heart rate increases, and there is an increase in epinephrine in the mouse's blood. What nervous system division is responsible for the mouse's physiological state

Answers

The sympathetic nervous system is responsible for the mouse's physiological state.

 

The nervous system divides into the central nervous system and peripheral nervous system.

In the central nervous system, we have the brain and the spinal cord.

The peripherical nervous system, which is all the nerves that are not in the spinal cord or the brain, is divided into:

The somatic nervous system, which is the one that makes the conscious movements of our body.The autonomic nervous system consists of:

-Sympathetic nervous system. It is the one that works under stress. It gives the fight or flight response preparing the body for a dangerous situation. It increases the heart rate and epinephrine's release. Epinephrine is a hormone that helps in this response stimulating the sympathetic system.

-Parasympathetic nervous system. It is the one that works in calm situations, like after we ate, regulating digestion, and trying to save energy for any upcoming event.

In conclusion, as there is an increase in epinephrine and heart rate, and the mouse is "fighting" against a scorpion, the nervous system division responsible for this physiological state is the sympathetic nervous system.

How would the carbon cycle be influenced by an increase in aerobic respiration?

Answers

Answer:

Cellular respiration does not affect the carbon cycle but is part of the carbon cycle. The 2 carbon cycles. carbon ( C ) is taken up by the plants and trees in the form of carbon dioxide ( CO2 ). Plants converts this CO2 into organic compounds such as glucose ( C6H12O6 ).

Explanation:

Increase in aerobic respiration will lead to increase in the amount of CO2 released into to the atmosphere due to respiration.

Aerobic respiration occurs when oxygen is combined with glucose to yield carbon dioxide and water. This is one of the major ways through which carbon dioxide enters the carbon cycle.

Note that the carbon cycle shows the movement of carbon in nature. Increase in aerobic respiration means that more carbon will be introduced into the atmosphere as carbon dioxide.

Al wonders if adding salt to water will affect how long it takes the water to freeze. Al thinks that salt water will freeze more quickly than fresh water. He decides to check his hypothesis by conducting an experiment. Al takes two ice trays and fills one with distilled water and the other with distilled water that has two tablespoons of salt added. He makes sure he puts exactly the same amount of water in each ice tray. Al takes the trays and puts them side by side in the freezer. Al checks the ice trays every 10 minutes to see if the water in each tray has begun to freeze. Al finds that after 20 minutes the water in the ice tray without the salt has started to form ice, while the ice tray with the salt water is still completely liquid.
