what kind of nucleic acid is found in retroviruses?
Answer:
A retrovirus is an RNA virus that is duplicated in a host cell using the reverse transcriptase enzyme to produce DNA from its RNA genome. The DNA is then incorporated into the host's genome by an integrase enzyme. The virus thereafter replicates as part of the host cell's DNA.

Goats are outside living on the sides of steep mountains. They are eating the
grass and bushes that grow there. It's a clear, sunny day on the mountainside.
What is happening to the carbon dioxide in the air? Is it ONLY being released (as a
product), ONLY absorbed (as a reactant), or being released AND absorbed?
CO2 is being both released by goats in exchange for O2 and absorbed by the plants in exchange for O2, too
4. There are two types of traits within a population. What vocabulary word does
this represent?
*
Overproduction
Variation
Descent with Modification
Adaptation
Answer:
The answer is Descent with Modification
Descent with Modification refers to the passing on of traits from parent organisms to their offspring. This passing on of traits is known as heredity, and the basic unit of the heredity is the gene.
In what direction do substances diffuse across the cell
membrane?
Answer:
Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient." The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane.

The tree population on Galveston Island has become more diverse due to human impact and planting non-native trees. During times of hurricane flooding, native trees that are more tolerant to salt water are surviving while non-native trees that are less salt tolerant are dying off. Which of the following explains how the tree population will continue to change overtime?
The salt tolerant tree population will decrease overtime due to increased flooding
The salt tolerant native tree population will continue to increase due to their adaptation
The non-native tree population will increase slowly overtime due to more hurricane occurrences
The non-native tree population will increase due to their adaptation

Explanation:
How does air pressure affect
breathing?
Answer:
When you inhale, muscles increase the size of your thoracic (chest) cavity and expand your lungs. This increases their volume, so pressure inside the lungs decreases. As a result, outside air rushes into the lungs. That's because a gas always flows from an area of higher to lower pressure.
Answer:
The air pressure in your lungs has to be less than the air outside your lungs, to get your lungs to inflate. This is because air moves from high pressure areas to low pressure areas. During bad weather and at high altitudes the air pressure is lower, making it harder for us to breathe.

What is used to regulate gas intake and output with a plant?
Answer-
The plants stomata!
Stomata regulate transpiration and CO2 intake by changing its size depending on the environmental signals. In optimum conditions, stomata are wide open, allowing gaseous exchange with the atmosphere.

so low that a(n)_1 occurs, threatening organisms like crabs and fish.
A)
neap tide
B)

c)
marine dead zone
D)
undertow current
The pollution in the Chesapeake Bay causes dead zone means low oxygen that can leads to suffocation in marine organisms like crabs and fishes. The correct option is C.
What is the Chesapeake Bay?The Chesapeake Bay is in United State. It is the largest estuary of US.
As due to increased pollutants in this, the marine organisms are facing dead zone due to low oxygen levels.
This marine dead zone causes the crabs and fishes to die due to suffocation and improper oxygen supply.
Thus, the correct option is C.

Explanation:
Renewable energy is also known as clean energy and it can be defined as a type of energy that are generated through natural sources or technology-based processes that are replenished constantly. Some examples of these natural sources are water (hydropower), wind (wind energy), sun (solar power), geothermal, biomass, waves etc.
Basically, a renewable energy source is sustainable and as such can not be exhausted.
Non-renewable energy refer to a type of energy that is generated through artificial sources or that cannot be replenished. It includes coal, natural gas, fossil fuels, petroleum
Many environmental advocates believe that biofuel made from palm oil is not an appropriate replacement for fossil fuels such as petroleum because tropical forests must be cleared to plant oil palms. Palm fruits are region selective plants and as such wouldn't didn't thrive in regions other than tropical forests.
What is significant drawback to transferring electricity produced by solar where sunshine is abundant to states where it is not
Answer:
The transfer could only occur during the day because it cannot store solar energy.
Explanation:
The transfer of electricity produced from solar energy only occurs during the day because it cannot store solar energy at a tremendous level. At homes, we can easily store the electricity made from solar energy with the help of batteries but for providing electricity to a state where thousands of houses are present, enormous batteries are needed to store it which can't be made because of very high cost so that's why the solar energy can not be stored.
