Answer:
Actually, all of these are required for DNA replication.
Explanation:
This is because DNA replication is the process where double stranded DNA are copied and produced from the parent DNA molecule. For DNA replication to occur there must be a strand of DNA that must be copied, the monomers from the parent molecule, the enzymes that carry out replication process, primase and topoisomerase.
Between 1984 and 2003, scientists mapped the human genome, which means they determined the pattern of billions of genes that make a human a human. Originally, it took years to map a single person’s total genome. By 2014 multiple genomes could be mapped in one day. What most likely allowed scientists to start mapping so much faster? a change to Mendel’s law of dominance more powerful computer technology the discovery of how germs work new scientists repeating gene experiments
Answers: a change to Mendel’s law of dominance
more powerful computer technology
the discovery of how germs work
new scientists repeating gene experiments
Answer:
More powerful computer technology
Explanation:
More powerful computer technology allowed the scientists to start mapping so much faster because powerful computer works very fast as compared to human brain. The activity or calculation which can be done by the human brain in hours, the computer done it in seconds due to its fast and quick response. So we can conclude from this discussion that powerful computer technology allowed the scientists to start mapping very fast.

Where would you expect precipitation to occur
I think the answer is clouds.
Precipitation is any type of water that forms in the Earth's atmosphere and then drops onto the surface of the Earth. Water vapor, droplets of water suspended in the air, builds up in the Earth's atmosphere. Water vapor in the atmosphere is visible as clouds and fog.
answer:
Precipitation is most abundant where air rises, and least abundant where it sinks. It also tends to be greater near oceans and lakes, and in higher elevations.

To summarize what you have learned about transcription, explain how a gene directs the synthesis of an mRNA molecule. Include in your explanation the words and phrases: base-pairing rules, complementary nucleotides, DNA, gene, mRNA, nucleotide, nucleus, and RNA polymerase
Answer:
Please find a detailed explanation of the process below
Explanation:
Transcription is the first stage of gene expression in living organisms in which a DNA sequence is used to synthesize a mRNA molecule. This process, which occurs in the NUCLEUS of eukaryotes and cytoplasm of prokaryotes, is catalyzed by an enzyme called RNA POLYMERASE.
- In the initial stage called INITIATION, RNA polymerase binds to the promoter of GENE and starts to unwind the double strand of the DNA sequence.
- The RNA polymerase, then, begins to add complementary NUCLEOTIDE bases following the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine will pair with Thymine (Uracil in RNA) while Guanine will pair with Cytosine i.e. T-A, A-U, G-C etc. This stage is called ELONGATION.
- The last stage called TERMINATION involves the stopping of the process because the RNA polymerase has encountered a termination signal.
A student used poster board to construct this model of DNA.Which statement describes this model of DNA?
Answer:
The model is inaccurate because the base pairs are incorrect.
Explanation:
The model of DNA that the student made was:
G-G
A-A
T-T
C-C
G-G
A-A
T-T
C-C
The model is pairing the bases incorrectly since guanine (G) forms a base pair with cytosine (C) and adenine (A) with thymine (T). In other words, the bases do not pair with the same type.
The DNA strands, which have deoxyribose, phosphate groups, and different bases, are together thanks to hydrogen bonds between the pairs. The pair G-C has three hydrogen bonds, while the pair A-T has two hydrogen bonds.

Only about 10 percent
of the energy from each
level of an energy
pyramid is available to
the trophic level above
it. (The rest is used to
power life processes or
is lost as heat.)
If the primary producers
have 10,000 units of
stored energy, how
much energy would you
expect to be transfered
to first-level, second-
level, and third-level
consumers?
Answer:
First leve consumer: 1,000 energy units
Second level consumer: 100 energy units
Third level consumer: 10 energy units
Explanation:
First level consumer: 1,000 energy units. Second level consumer: 100 energy units. Third level consumer: 10 energy units.
What is trophic level?The group of species in an ecosystem that are at the same level in the food chain is referred to as a trophic level. A food chain has five basic trophic levels, each of which has a different nutritional relationship to the main energy source.
The Sun is any ecosystem's main source of energy (although there are exceptions in deep sea ecosystems). Primary producers, sometimes referred to as autotrophs, receive their energy input from the Sun's solar radiation.
The first trophic level is made up of primary producers. Consumers, also known as heterotrophs, make up the remaining trophic levels; heterotrophs are unable to reproduce.
Therefore, First level consumer: 1,000 energy units. Second level consumer: 100 energy units. Third level consumer: 10 energy units.

A plant is observed to have deep roots and tendrils that wrap around objects. Which pair of tropisms correctly describe these responses?
1.geotropism and phototropism
2. phototropism and thigmotropism
3. hydrotropism and geotropism
4.hydrotropism and thigmotropism
Answer:
4
Explanation:
The correct answer would be hydrotropism and thigmotropism.
Hydrotropism is defined as the movement of a plant or its organs to or away from moisture. The deep root growth of plants is a way of seeking or growing towards moisture that is present deep in the soil. Hence, the root is said to exhibit positive hydrotropism.
Thigmotropism, on the other hand, is the growth or movement of plants or their organs to or away from touches. In this case, the tendrils of the plant that wraps around objects they come in contact with are showing positive thigmotropism.
The correct option is, therefore, option 4.

Explanation:
when the body removes carbon dioxide bu the way of respiratory system what happens to the ph of blood
the more carbon dioxide in the blood the more acidic it will be. so when it is removed the acidity will decrease.
so the pH increases
When the body removes carbon dioxide, the PH of blood increases
The body control the blood's acid-base balance through different ways. The organs used for this control is lung, kidney and buffer systems.
The lung can control blood pH through the release of carbon dioxide. Carbon dioxide acidic and its accumulation in the body leads to an increase in PH.
When the blood PH is too low (i.e. acidic), the body increases breathing so as to expel(remove) more carbon dioxide thereby increasing the PH of the blood.

What is the locomotory structure of yeast
Answer:
Yeast cell structure
Each yeast cell has a distinct cell wall enclosing granular cytoplasm, within which can be seen a large vacoule and a nucleus (Fig. 214). The vacuole varies much in size according to the state of activity of the cell.
Yeast contains almost the same organelles of a mature eukaryotic cell. Nucleus, Golgi apparatus, mitochondria, endoplasmic reticulum, vacuole, and cytoskeleton are the most important one. Yeast cell particle size is typically of 5×10μm.
Explanation:
Yet, we don't always think of yeast as something remarkable. Instead, it's often perceived as plain or dull—a single-celled organism that, like a plant, lacks the ability to move on its own accord.
Which statement about identical twins and fraternal twins is correct in regards to DNA?
A. Identical twins have different DNA, and fraternal twins have different DNA.
B. Fraternal twins share the exact same DNA, but identical twins do not.
C. Identical twins and fraternal twins share the exact same DNA.
D. Identical twins share the exact same DNA, but fraternal twins do not.
Answer:
D. Identical twins share the exact same DNA, but fraternal twins do not.
Explanation:
Identical twins are the twins formed from one egg provided by their mother and one sperm provided by their father. In contrast, fraternal twins are formed from two different sperms and two different eggs from the same father and mother.
Due to the fact that identical twins are as a result of one fertilized egg dividing into two, they share the same exact DNA. On the other hand, fraternal twins do not share the same exact DNA because they are formed from separate eggs and separate sperms.

the process where maiten magma rises and sinks due to tempature of difference, CRIVNCONEO
Answer:
Convection
Explanation:
The process where molten magma rises and sinks due to the temperature difference is known as CONVECTION.
This occurs when the hot magma moves upward and is cooled and moves downward again to be heated due to temperature difference, and similarly when cold magma moves upward and is heated and moves downward again to be cooled due to temperature difference.
Hence, in this case, the correct answer is CONVECTION
