Answer:
RNA is single standard while DNA is double standard
RNA contains the sugar ribose, while DNA contains deoxyribose.
RNA contains uracil, while DNA contains thymine.
RNA can leave the nucleus, while DNA cannot.
Explanation:
RNA is a single-stranded structure while DNA is a double-stranded structure while the former containing the uracil base and the latter containing the thymine base.
What is the difference between RNA and DNA?DNA stands for deoxyribonucleic acid which is defined as a double-stranded molecule consisting of a long chain of nucleotides whereas RNA stands for ribonucleic acid which is defined as a single-stranded molecule consisting of a shorter chain of nucleotides. DNA replicates on its own, it is self-replicating but RNA does not replicate on its own.
The base pairing is of DNA is as follows: GC (Guanine pairs with Cytosine) A-T (Adenine pairs with Thymine) while the base pairing of RNA is as follows: GC (Guanine pairs with Cytosine) A-U (Adenine pairs with Uracil). RNA has the sugar ribose while DNA has the sugar deoxyribose. DNA is located in the nucleus of a cell and in the mitochondria while the RNA is found in the cytoplasm, nucleus and in the ribosome.
Thus, RNA is a single-stranded structure while DNA is a double-stranded structure while the former containing the uracil base and the latter containing the thymine base.

The more genetic variation a population has, the more likely it is that some individuals will migrate.
what is population ?A discrete accumulation identifiable characteristics such as people, animals with the objective of analysis and data collection is called a population.
A population consists of a same group of species who reside in a particular geographical place with their reproductive capacity to interbreed.
In a population Not all individuals are able to survive and reproduce due to genetic variations in them, a local population is restricted to a smaller area or can occupy a larger area, making up for the entire species.

If two populations of people share the same DNA "spelling difference" (i.E., mutation), what does this mean about these two populations?
Answer:
It could mean that those two populations could be common ancestors because the spelling differences are the same
Explanation:
The similar spelling variations between the two populations could imply that they share common ancestry.
What is DNA?Deoxyribonucleic acid, or DNA, is the name given to the genetic material carried by humans and nearly all other species. An individual's DNA is present in nearly all of their cells.
Nucleotides are the molecular building components that make up DNA. A phosphate group, a sugar group, and one of four different nitrogen bases make up these building components. Nucleotides are joined into chains and the locations of the phosphate and sugar groups are switched to form DNA strands.
Every cell in the body has DNA in its nucleus. Groups of these firmly bound fragments make form chromosomes. The majority of people possess 46 pairs of chromosomes, or 23 pairs per pair.
Thus, The similar spelling variations between the two populations.

This oceanic zone contains some of the
deepest parts of the ocean.
A. Kelp Forest
B. Abyssal Zone
C. Coral Reefs
The abyssal zone, which lies between 4,000 and 6,000 meters (13,000 and 20,000 feet) below the surface, is the deepest region of the ocean. So, option B is the answer.
The region of the ocean that lies beyond the continental shelf is commonly referred to as the oceanic zone. The sunshine zone, twilight zone, midnight zone, and abyssal zone are the four vertical zones that make up the open ocean.
Abyssal zone is characterized by high pressure, low temperatures, and very little light.
Kelp forest is found in shallower areas, often between 20 and 100 meters deep and Coral reefs are located in tropical, shallow waters.
Therefore, option B is correct.

Leading and lagging DNA strands exist at a replication fork because ___________.A. the DNA polymerase can add new nucleotides onto either the 3' end or the 5' end B. the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5' end C. the two strands of DNA are parallel and DNA polymerase can only add new nucleotides onto a 3' D. end the two strands of DNA can be either parallel or antiparallel the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 3' end
Answer:
B. the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5' end
Explanation:
Deoxyribonucleic acid, known as DNA, is the genetic material of a cell, which must first undergo replication i.e produce two identical copies of itself, before a cell can divide. During replication, the double stranded DNA unwinds into a replication fork consisting of two single strands of DNA.
These single strands of DNA are called leading strand (runs from 3'-5') and lagging strand (runs from 5'-3'). These single strands that runs at opposite direction from one another exists at the replication fork because the two strands of DNA are antiparallel i.e. are opposite to one another, and DNA polymerase can only add new nucleotides onto a 5' end.
Leading and lagging DNA strands exist at a replication fork because the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5 'end.
A replication fork is the juncture between two strands of DNA when it is replicating itself.
In each of them (speaking of the homologous strands) the opposite chain is carried out to have the double genetic information when approaching cell division.
The direction in which the enzymes act is unique from 5 'to 3', this determines the template chain must have the direction 3'→ 5', so that the new chain in formation, complementary and antiparallel, has the direction 5 '→ 3' coinciding with the enzyme's working system.The basic reaction that takes place in replication is a polymerization reaction, in a growing DNA chain a nucleotide is incorporated whose base is complementary to that of the template chain.The DNA polymerases at the two ends of the free nucleotide to be incorporated use its phosphate group or 5 'end to add it to the growing chain.Therefore, we can conclude that leading and lagging DNA strands exist at a replication fork because the two strands of DNA are antiparallel, and DNA polymerase can only add new nucleotides onto a 5 'end.

Explanation:
because human takes oxygen and plants take carbon dioxide
Answer:
well, what we can do here is eliminate what we know. It's not A, because ALL living organisms reproduce. (examples include humans, cows, plants, etc.) for now, until we see the other answers, we will skip b. It can't be C, because on a trusted website, it states that the unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Rudolf Virchow later made important contributions to this theory. ... All organisms are made up of one or more cells.
If we take a look at D, It could be true because in another trusted website, it states that Oxygen helps organisms grow, reproduce, and turn food into energy. ... Although other animals may use different organs to breathe with, they all get oxygen into their bodies through respiration. So, Looking back up to B, it seems less likely now that we've viewed everything. D is the answer, I wasn't paying attention earlier, haha.

Answer:
2. In the natural environment, plants produce their own food to survive. As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration".
3. Both cellular respiration and fermentation are process that break down food and convert the chemical energy stored in the food to ATP molecules. Both these processes begin with glycolysis and convert glucose to pyruvate. ... Fermentation only uses the latter.
4. Energy is usually absorbed during photosynthesis.
Photosynthesis is the process whereby green plants manufacture their food in the presence of sunlight(energy source), water and carbon dioxide:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
↑
Sunlight
Sunlight supplies solar energy that is used to converted the chemical species into glucose that stores chemical energy.
Respiration is the reverse of photosynthesis. In this reaction, oxygen gas combines with glucose to produce energy with water and carbon dioxide as by products. The energy stored in photosynthesis is released during respiration.
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O ↑ energy
