The eukaryotic cells of humans share many characteristics with bacterial cells, including single stranded DNA. Thus option D is correct.
what is the structure of DNA ?DNA is referred as deoxy ribo nucleic acid, which is a nucleic acid, with a left handed double helical structure, are the basic unit of every living cell
It carry all genetic material responsible for expression of a character of an living organism; It is made up of nitrogenous base, sugar mainly pentose sugar and phosphate.
Nitrogenous base are purine and pyrimidine such as adenine, guanine, thiamine, cytosine; Adenine can pair with thiamine by two hydrogen bond where as cytosine can pair with guanine by three hydrogen bond.

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
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.
Explanation:
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.
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.

O Water is denser than isopropanol, so the water layer will always be below the isopropanol layer if they are both in the same container. What does this tell you about the make-up of the pigments for each specimen?
Answer:
One is polar and the other is non-polar.
Explanation:
The makeup of both water and isopropanol is different from each other due to their polar nature. Water is a polar substance means that it makes poles i.e. positive or negative while on the other hand, isopropanol is non-polar substance so due to this reason water and isopropanol make different layers. If both are polar or nonpolar substances so they will able to mix with each other.
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.
Bird guides once listed the myrtle warbler and Audubon's warbler as distinct species because of differences in color patterns of the feathers and size of the beak. Recently these birds have been reclassified as eastern and western forms of a single species, the yellow-rumped warbler, based on the observation that the two forms interbreed often in nature and the offspring have good survival and reproduction. The earlier classification into two species was using a species concept; the reclassification is using the species concept. _________
Answer:
morphological; biological
Explanation:
The morphological species concept highlights the importance of physical traits to delimit species. This concept is useful for classifying asexually-reproducing organisms and where lack information on interbreeding (for example, to classify fossils). On the other hand, the biological species concept states that one species represent a group of organisms that can interbreed (or potentially can interbreed) in order to produce fertile offspring. The biological species concept is nowadays the most widely accepted concept to define species.
A red frog and a blue frog mate and have offspring. If the gene is Codominant, what will be the color of their offspring?
Answer:
The correct answer is - blue and red both.
Explanation:
Codominance is the type of inheritance pattern in which alleles interact differently with one other. In this type of inheritance, neither allele is dominant or recessive and both traits are visible in the progeny if both alleles are present together in heterozygous conditions.
Here, in this case, Red frog and the blue frog are in codominance so the cross of these frogs leads to both colors that will be express in offspring together.

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 happens when there is a decrease in carbon dioxide during gas exchange in the body?
Answer:
Increased carbon dioxide means increased blood acidity, while decreased carbon dioxide means increased blood acidity.
The bicarbonate reaction is reversible, which allows bicarbonate to turn back into dissolved carbon dioxide to diffuse from the alveolus.

How does the immune system respond when a virus is detected?
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.

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.
