Answer:
1. smaller 2. be faster
Explanation:
Eukaryotes have highly specialized systems that repair G-T mismatches in DNA. G-T pair repair in these systems yields G-C base pairing and not A-T base pairing. While there are other repair mechanisms for base mismatches, why might cells require a specialized system in order to repair G-T mismatches specifically
The DNA repair systems are specialized systems that are in place to correct every mistake that comes up including the incorporation of incorrect nucleotides during the biological processes like DNA replication and so on.
Cells may require a specialized system in order to repair G-T mismatches specifically because the G-T mismatches are more common and the tendency for cytosine to be converted to thymine is higher than for guanine to be converted to Adenine.
Methylation of cytosine to thymine in the G-C pair is a lot common and this process is required in some biological processes.
This methylation leads to a change to G-T mismatch but this mutation does not remain for long before the thymine is corrected back to cytosine.
Therefore, a specialized system is utilized for this G-T repair, methylation of cytosine to thymine is not essentially a mutation as thymine is converted back to cytosine immediately by this specialized system after the process has taken place.

2. The ber of of an element is equal to the num- in the nucleus of its atoms.
Answer:
All atoms can be identified by the number of protons and neutrons they contain. The atomic number (Z) is the number of protons in the nucleus of each atom of an element. In, a neutral atom the number of protons is equal to the number of electrons, so the atomic number also indicates the number of electrons present in the atom. The chemical identity of an atom can be determined solely from its atomic number. For example, the atomic number of nitrogen is 7. This means that each neutral nitrogen atom has 7 protons and 7 electrons. Or, viewed another way, every atom in the universe that contains 7 protons is correctly named “nitrogen.”

Which of these describe a warm front?
Question 3 options:
Warm and cool air mass that are not strong enough to move one another
Cold air meets warm air, fast moving and stormy. Severe weather is likely.
Warm air meets cold air. Slow moving with less severe weather.
Ocean surface temperature is greater than 80F.
Answer:
the 3rd option is right
Explanation:
oooo
Warm air meets cold air. Slow moving with less severe weather. So the correct option is C.
What is a warm front?The area in which a warm air mass is displacing a cold air mass is known as a warm front. The air behind such a warm front is warmer and more humid than the air in front of it. Warm fronts typically migrate from the southwest to the northeast. The air gets substantially warmer and more humid than it was before a warm front moves through.
A solid line with semicircles pointing in the direction of the flow and toward the colder air symbolizes a warm front. A warm front is indicated on colored weather maps by a solid red line.
A warm front should be considered while analyzing the front if warmer air is replacing colder air. A cold front should be considered while analyzing the front if colder air is displacing warmer air.
Therefore the correct option is C.

You are observing a population of squirrels that have red or black fur. Coat color in these squirrels is determined by one gene with two alleles, where red is dominant to black. In your population, you count 100 squirrels and find 84 red squirrels and 16 black squirrels. What is the frequency of the black fur allele
Assuming that the diallelic gene, which codes for fur color, express complete dominance, and following H-W equilibrium, the frequency of the black fur allele is f(r) = 0.4
--------------------------------
Available data:
Single, diallelic gene coding for fur colorRed is the dominant traitBlack is the recessive traitTotal number of squirrels, N = 10084 animals are red16 animals are blackWe need to calculate the frequency of the recessive allele.
We will say that,
R is the dominant allele that codes for redr is the recessive allele that codes for blackWe will assume complete dominance, where R completely masks the expression of r allele, so heter0zyg0us individuals express the dominant trait.
Following Hardy-Weinberg equilibrium, the allelic frequencies in a locus are represented as p and q. Assuming a diallelic gene,
p is the frequency of the dominant allele, q is the frequency of the recessive allele.The genotypic frequencies after one generation are
p² (H0m0zyg0us dominant genotypic frequency), 2pq (Heter0zyg0us genotypic frequency), q² (H0m0zyg0us recessive genotypic frequency).So, if we have the genotypic frequency of the recessive phenotype (black fur) we can get the allelic frequency.
We know that there are 16 black suirrelsAnd we know that the total number of individuals in the population is 100So the frequency of the black squirrels -F(rr)- in the population is,
F(rr) = q² = 16/100 = 0.16
Now, by taking the root square of this value, we will get the allelic frequency, f(r).
F(rr) = q² = 0.16f(r) = q = √q² = √0.16 = 0.4The frequency of the black fur allele is f(r) = 0.4.

where is the good ozone located
where is the bad ozone located
Answer:
Good ozone-stratosphere
Bad ozone-troposphere
Explanation:
The stratosphere or “good” ozone layer extends upward from about 6 to 30 miles and protects life on Earth from the sun's harmful ultraviolet (UV) rays.
In the troposphere, near the Earth's surface, human activities lead to ozone concentrations several times higher than the natural background level. Too much of this ground-level ozone is 'bad' as it is harmful to breathe and also damages vegetation.

Which term best describes a molecule of ATP?
A. a triphosphate
B. a phospholipid head
C. a phosphorylated DNA nucleotide
D. a modified RNA nucleotide
E. a glycosidic group
A modified RNA nucleotide is the best term that describes a molecule of ATP.
ATP is an organic molecule of the nucleotide type, it is composed of a molecule of adenine (nitrogen base) linked to a carbon atom of a molecule of ribose (pentose), a sugar that in turn has bonded three phosphate ions to another carbon atom.
Structurally, ATP is a nucleotide of RNA, nucleotides are organic molecules composed of a covalent bond between a nucleoside and a phosphate group (PO43-).Nucleosides, on the other hand, are organic molecules composed of a pentose-type sugar and a nitrogenous base.Therefore, we can conclude that ATP is called a nucleotide that is essential for cells to obtain energy.

A runner travels around a rectangle track twice, with length =50 meters and with =20meters. Determine the distance and displacement.
Answer: this is the answer
Explanation:
Solution
Circumference of rectangle = 2(50 meters) + 2(20 meters) = 100 meters + 40 meters = 140 meters.
Travels around rectangle 2 times = 2(140 meters) = 280 meters.
Distance = 280 meter.
Displacement = 0 meter. (runner back to start point)
Average speed = distance / time elapsed = 280 meters / 100 seconds = 2.8 meters/second.
Average velocity = displacement / time elapsed = 0 / 100 seconds = 0.

Describe how editing CFTR would impact gene expression. Draw a model that illustrates your description
Answer:
Idont know that but you can answer that
Editing the CFTR gene can potentially impact gene expression in several ways, depending on the type of editing and the specific mutation being targeted, and one approach to editing the CFTR gene is through the use of gene therapy.
What is gene editing?Gene therapy and gene editing are two potential approaches for treating CF by correcting the genetic defect responsible for the disease. Gene therapy involves introducing a functional copy of the CFTR gene into cells, while gene editing involves correcting the specific mutation in the CFTR gene responsible for CF. In gene therapy, a functional copy of the CFTR gene is introduced into cells using various methods, such as viral vectors, lipid nanoparticles, or gene editing technologies such as CRISPR-Cas9. Once the functional copy of the gene is successfully delivered into the cells, it can lead to increased expression of the CFTR protein, which can potentially improve the regulation of salt and water movement in and out of cells and reduce the severity of CF symptoms.
Hence, editing the CFTR gene can potentially impact gene expression in several ways, depending on the type of editing and the specific mutation being targeted, such as through gene editing.
