Answer:
D
Explanation:
DNA pairs with adenosine, thymine, cytosine, and guanine
RNA pairs with uracil, adenosine, cytosine, and guanine
Option D is correct because RNA pairs uracil with adenine instead of thymine, unlike DNA. Other differences include ribose in RNA versus deoxyribose in DNA and RNA being single-stranded while DNA is double-stranded.
The correct answer to the question is Option D: pairs uracil with adenosine instead of thymine.
A. has deoxyribose as the sugar within its nucleotide components: This statement is incorrect because RNA contains ribose, not deoxyribose. Deoxyribose is found in DNA.B. contains two strands wrapped in a helix: This is incorrect because RNA is typically single-stranded, whereas DNA is double-stranded.C. contains nitrogenous bases: While this is true for both RNA and DNA, it does not 'unlike' DNA. Both types of nucleic acids contain nitrogenous bases.D. pairs uracil with adenosine instead of thymine: This is the correct statement. Unlike DNA, RNA uses uracil in place of thymine and pairs it with adenine.In summary, RNA and DNA differ primarily in their sugars (ribose vs. deoxyribose), the presence of uracil instead of thymine, and RNA being single-stranded compared to the double-stranded DNA.

such as fungi and bhacteria:
Answer:
Fungi and bacteria help other things such as wast and minerals break down and reproduce. They are very important role of organisms. Without them our grounds would be full of trash and non broken down minerals. Our lands would be toxic on the outside, and many animals would die. It isn't on the food chain because, nothing really eats it, because some are toxic, but we also need them for the environment and breaking down things.
Explanation:
I searched it up. I hope this helps! Have a nice day. Bye. :)
Organisms like fungi and bacteria are not drawn into the food chain because they perform the role of decomposers in nature. While the food chain gets initiated with the producers which are plants.
What is a Food chain?The food chain may be defined as the process through which the transfer of energy from producers to top consumers through a series of organisms. One organism can hold only one position. The flow of energy is very easy to calculate.
Both fungi and bacteria break down the complex substance into smaller components which are easily consumed by plants and other organisms. They make the earth free from toxic compounds by breaking them into smaller usable forms. So, they are also known as the sweepers of the environment.
Therefore, fungi and bacteria perform the role of decomposers in nature.

what does the mitochondria do for our body, what benefits does it give?
Answer: Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. The biochemical processes of the cell are known as cellular respiration.
Explanation:
Answer:
Mitochondria provides energy to the body.
Explanation:
Mitochondria is an important organelle of the cell. Mitochondria is also called power house of the cell because it generates energy in the form of Adenine tri phosphate (ATP) by the breakdown of glucose molecules in the process of respiration. In the presence of oxygen, mitochondria produce more ATP while without oxygen very low ATP is produced.
All living things are made of one or more cells. Here are two types of cells: an animal cell and a plant cell. Explain why animal cells do not have the organelle called the chloroplast but the plant cell does.
A) Plants do not move but animals do move. Because plants do not move they need the chloroplast for protection.
B) Plants make food, glucose, through photosynthesis in the chloroplast.
C) Animals undergo photosynthesis to stay alive and for this, they use the chloroplast.
D) The chloroplast helps plant cells regulate the water that moves in and out of the vacuole.
Answer:
B) Plants make food, glucose, through photosynthesis in the chloroplast.
Plants make food, glucose, through photosynthesis in the chloroplast. Therefore, option (B) is correct.
What is a chloroplast?A chloroplast is an organelle found in plant cells and some protists that is responsible for photosynthesis. It contains a green pigment called chlorophyll, which is responsible for the plant's green color and helps absorb light energy from the sun. The chloroplasts use this energy, along with carbon dioxide and water, to produce glucose and oxygen through a process called photosynthesis.
Chloroplasts are unique because they have their own DNA and can replicate themselves. They are also surrounded by a double membrane that helps regulate what enters and exits the organelle. Within the chloroplast, there are stacked structures called thylakoids, which contain chlorophyll and other pigments. The thylakoids are arranged in stacks called grana, and the space between the grana is called the stroma. The stroma contains enzymes that are essential for the reactions of photosynthesis. Chloroplasts play a crucial role in the survival of plants and the food chain, as they are responsible for producing the energy that supports most life on earth.

A certain reptile species is a herbivore and exists only on an isolated island. Which of the following would most likely result in the extinction of the reptile species over a period of twenty thousand years?
A. The reptile species produces many offspring with many unique traits, and the vegetation remains constant.
B. The reptile species produces few offspring with some unique traits, and the vegetation remains constant.
C. The reptile species produces few offspring with no unique traits, and the vegetation changes quickly.
D. The reptile species produces many offspring with some unique traits, and the vegetation changes slowly.
Answer:
i think its b
Explanation:
Final answer:
Option C, where the reptile species produces few offspring with no unique traits, and the vegetation changes quickly, would most likely result in the extinction of the reptile species over a period of twenty thousand years.
Explanation:
The most likely scenario that would result in the extinction of the reptile species over a period of twenty thousand years is option C. This is because if the reptile species produces few offspring with no unique traits, and the vegetation changes quickly, the species will not have the ability to adapt to the new environment and may struggle to find enough food to survive.
Without the ability to adapt and thrive in the changing vegetation, the reptile species would likely face extinction over time.

Choose the correct sequence of the prokaryotic operon. A) gene, operator, promoter B) promoter, operator, gene C) operator, promoter, gene D) operator, gene, promoter
Answer:
The correct answer is option B, that is, promoter, operator, gene.
Explanation:
In a prokaryote, just in front of the operator, the promoter is located, and just in front of the structural genes, the operator is located. All these in combination give rise to an operon.
Any gene, which codes for an enzyme or a structural protein is termed as a structural gene, in the lac operon, a structural gene codes for three distinct kinds of enzymes. A short sequence of DNA is situated just in front of the structural gene, which is known as the operator. An operator functions as a switch for transcription, that is, it monitors whether the process of transcription will take place or not.
Just in front of an operator, a sequence of a promoter is present, and for the transcription and translation of all the structural genes, the RNA polymerase needs to combine first with the promoter. In case, if no transcription is to take place, then the operator allows the repressor to bind with it and prevent the attachment of RNA polymerase with the promoter. Hence, the correct sequence of a prokaryotic operon is a promoter, operator, and gene.

A plant takes in carbon dioxide (CO2) from the atmosphere and uses it to make glucose (C6H12O6) through photosynthesis. Later a deer eats the leaves of the plant obtaining the plant’s glucose. After respiration, the deer exhales carbon dioxide (CO2) back into the atmosphere. This is an example of _________________.
Answer:
the carbon cycle
Explanation:
The carbon cycle is illustrated by a plant using photosynthesis to create glucose from CO2, which is then consumed by a deer. After metabolizing the glucose through cellular respiration, the deer releases CO2 back into the atmosphere.
A plant takes in carbon dioxide (CO2) from the atmosphere and uses it to make glucose (C6H12O6) through photosynthesis. Later a deer eats the leaves of the plant, obtaining the plant's glucose. After respiration, the deer exhales carbon dioxide (CO2) back into the atmosphere. This is an example of the carbon cycle.
During this carbon cycle, carbon dioxide is used by plants to make carbohydrates such as glucose. Through the process of photosynthesis, they convert atmospheric carbon dioxide into organic carbon, with oxygen being released as a byproduct. When an animal like a deer consumes the plant, it takes in the carbon within the glucose. Through cellular respiration, animals metabolize the glucose, which combines with oxygen to produce carbon dioxide, water, and energy. The carbon dioxide, now a byproduct of respiration, is released back into the atmosphere, completing the cycle.
