46. A sample of human DNA is made up of approximately 30% adenine. Based on
this information, and the base pairing rules, approximately how much cytosine
found in human DNA?
A 70%
B 20%
C 30%
D 10%
Help please
Answer:
its A/F
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%.

Binary fusion is one of the asexual reproduction. Example: Bacteria, Amoeba.
Explain the effect of activity on a heart rate
Answer: Exercise causes the heart to pump blood into the circulation more efficiently as a result of more forceful and efficient myocardial contractions, increased perfusion of tissues and organs with blood, and increased oxygen delivery. Aerobic exercise trains the heart to become more efficient.
Explanation:
PLEASE MARK ME AS BRAINLIEST
Answer:
Pretty much the more activity you do, or the more intense it is, the faster your heartrate will be. Your heart needs blood, and when you're exercising the blood is pumping through your body faster.

Which of the following organisms in the soil food chain does not obtain energy directly from plants?
a. bacteria
b. fungi
C. protozoa
d. nematodes
Answer:
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.

The thallus of a mold consists of long, branched, threadlike filaments of cells called _________ that form a tangled mass called a
Answer:
Hyphae; mycelium.
Explanation:
Fungi can be defined as living microorganisms that are eukaryotic in nature and are able to reproduce using both means of reproduction i.e both asexually and sexually. Also, fungi do not have chlorophyll but are of great importance to the human world both scientifically and practically.
A thallus can be defined as the vegetative or bodily structure of fungi. Thus, the various forms of fungi are;
I. Yeast.
II. Mushroom.
III. Mold.
A mold is typically multicellular (has more than one cell) and filamentous in nature. The thallus of a mold consists of long, branched, threadlike filaments of cells called hyphae that form a tangled mass called a mycelium.
The thallus of a mold consists of long, branched, threadlike filaments of cells called Hyphae that form a tangled mass called a mycelium.
What are hyphae and mycelium in fungi?Hyphae are the tubular projections of multicellular fungi that form a filamentous network. Fungal hyphae release digestive enzymes in order to absorb nutrients from food sources.
mycelium, the mass of branched, tubular filaments of fungi. The mycelium makes up the thallus, or undifferentiated body, of a typical fungus.
Thus, hyphae and mycelium is the correct answer.

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.

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.
