Explanation:
One advantage is that sexual reproduction provide variation which can help living things survive in different environment. Asexuals cannot have variation.
What is sexual reproduction?When sperm from a male parent fertilizes an egg from a female parent during sexual reproduction, the result is an offspring that is genetically distinct from both parents.
The genetic diversity of organisms is a result of sexual reproduction. Meiosis, a process that creates sperm and egg cells, is the first step in sexual reproduction.
Because they have half as many chromosomes as the parent, these cells are known as haploids. A diploid zygote is created during sexual reproduction when a male parent's haploid sperm fertilizes a female parent's haploid egg.
Therefore, One advantage is that sexual reproduction provide variation which can help living things survive in different environment. Asexuals cannot have variation.

Answer:
Has more offspring that have the ability to survive and reproduce themselves.
Explanation:
Evolution fitness can be defined as a characteristic or quality possessed by living organisms and determines their adaptability, as well as level of success in terms of reproduction i.e giving birth to offsprings.
Hence, if you say that a ground squirrel has greater evolutionary fitness than another ground squirrel in the same population, you mean that the animal has more offspring that have the ability to survive and reproduce themselves.

C
Explanation:
Protozoa have been classified into three trophic categories: the photoautotrophs which harness the sun's radiant energy in the process of photosynthesis; the photoheterotrophs, which although phototrophic in energy requirements, are unable to use carbon dioxide for cell synthesis and must have organic carbon compounds
Protozoa in the soil food chain does not obtain energy directly from plants. So, the correct option is C.
Who are Protozoa?Protozoa is defined as a group of single-celled eukaryotes, which is either free-living or parasitic, that feed on other microorganisms or on organic matter such as organic tissues and debris.
Protozoa are classified into two trophic categories:
Photoautotrophs that harness the Sun's radiant energy in the process of photosynthesisPhotoheterotrophs which although phototrophic in energy requirements, are unable to use carbon dioxide for cell synthesis and must be organic carbon compounds.Thus, Protozoa in the soil food chain does not obtain energy directly from plants.

Answer:

Explanation:
A sample of human DNA is made up of approximately 30% adenine. The quantity of cytosine found in human DNA will be 20%. The correct option is B.
What is DNA base pairing?DNA base pairing is the pairing or joining of DNA bases to each other with hydrogen bonds. There are four types of bases present in DNA. They are adenine, thymine, cytosine, and guanine.
Adenine pairs with thymine with double hydrogen bonds and cytosine joined with guanine with triple bonds of hydrogen. The pairing between these base pairs is alternated in the sequence of DNA.
According to the base pairing rule. There will be 100% of these bases present together. So if there is 30% adenine, there will be 30% thymine. The total becomes 60%. Now remain is 40%. So there will be 20 % cytosine and 20% guanine.
Thus, the correct option is B 20%.

Describe how ATP synthase produces ATP.
Answer:
so it spins the hydrogen molecules to make the ATP
Explanation:
it occurs in the inner membrane of the mitochondria. The electrons drop off the energy and the hydrogen atoms are moving through the Protein channels/pumps. after that the NADH turns into nad+ and the fadh2 turns into fad. these then go back to the citric acid cycle to get the electrons back. (known as electron carriers) the hydrogen molecules get pumped up to the inner membrane space which would be active transport since we are going from low to high concentrations. the hydrogen molecules go down the atp synthase which spins to make the atp. this would be passive transport since its moving from high to low concentrations.

Investigate four substances containing nitrogen or phosphorous that are related to biological processes, and explain their respective roles in those processes. (Examples: DNA, RNA, amino acids, and enzymes).
Answer:
Well, you already have the answer, but I can try to elaborate XD
So, DNA: contains genetic information that is necessary for biological functioning and reproduction.
More specifically, it contains the genetic instructions through gene encoding that instructs the cell what to do. A specialized complex ribosome interacts with the DNA molecules and "reads" it, changing the genes from the DNA into proteins that the cell as a whole can function upon. It is also crucial to forming a whole cell in offspring, since only the genes from the two parents combined (in humans at least) can produce an offspring with all genes intact. Those who do not have genetic disorders, a famous one being Down Syndrome.
Next, RNA: a molecule necessary for expressing genes and making proteins.
Connecting to the paragraph above for DNA, RNA also assists in the process by reading the ribosome that reads the DNA itself. Complicated, I know. All you have to know, however, is that the RNA, in this case called mRNA since it serves as a messenger, hence, the "m", reads the codons produced by the ribosome when it reads the DNA, and makes proteins according to those codons, and those proteins then scatter all across the cell to execute instructions.
Now, we move onto nitrogen and phosphorous: both are found in amino acids, the building blocks of proteins.
That is actually partially wrong. Amino acids do not contain phosphorous, but do contain nitrogen. Not exactly sure what went wrong on your end there, but nitrogen is a basic building block for amino acids, which are basic building blocks themselves for proteins. To be more clear, amino acids are made of carbon, hydrogen, oxygen and nitrogen atoms. No phosphorus there!
Finally, enzymes: special proteins that accelerate chemical reactions in cells.
This is correct. Enzymes typically lower the activation energy required for reactions to happen. More specifically, enzymes make the reaction molecules more active, hence, lowering the threshold for the amount of energy you have to put in before the molecules start crashing into each other hard enough to have a chemical reaction. Of course, enzymes do not participate in the reaction itself, which makes them incredibly useful for spurring on chemical reactions since they can be used multiple times.

QUESTION: this for the other version.. " Investigate substances containing carbon or oxygen that relate to biological processes. Explain their main function in those processes. "
ANSWER: I chose to investigate four substances: carbon dioxide, ethanol, glucose, and cellulose. According to my research, these are the main functions of these substances in various biological processes:
Carbon dioxide: Carbon dioxide is a product of aerobic respiration. Most living organisms exhale carbon dioxide while plants inhale it in the respiratory process. Carbon dioxide is converted to organic matter in the process of photosynthesis carried out by autotrophs.
Ethanol: The process of fermentation gives rise to ethanol, which is an alcohol. Ethanol is formed through a type of anaerobic respiration, that is, respiration without the use of oxygen.
Glucose: Glucose is a form of carbohydrate. It is nothing but simple sugar that stores energy in plants and animals.
Cellulose: Cellulose is an organic polymer used to make cell walls in plants.
