but can you guys help me with this question pls it on a picture and I need a answer and a person to explain why is it that answer
A. The sun heats the air at the equator, followed by hot air rising and moisture condensing
B. Air moves towards the poles as it cools
C. The dry air moves back to the equator, picking up a lot of moisture on the way
D. The air sinks around 30° latitude and is very dry.
Answer:
B. Air moves towards the poles as it cools
Explanation:
The image represent convection cell or Hadley cell is a natural phenomenon in the atmosphere that occur due to difference in the density within a body of liquid or gas. These differences in density causes rise and fall in currents.
The process in step A refers to when hot air moves up and in the step B, the hot air encounters a cold surface, it direct exchange the heat with cold surface and the air cools down and move towards the poles.
Hence, the correct answer is "B. Air moves towards the poles as it cools".

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%.

Which of the following is an example of specific immunity?
Answer:
Immunity to Small Pox
Explanation:
Over the years, Europeans had built up an immunity to smallpox because many had contracted the disease and still survived. As the population grew children were born with some immunity to the disease. When the Europeans arrived in the Americas, and smallpox spread around the native peoples, the Europeans did not contract the disease because they were immune. However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.

pack over the shaved area. The shaved area grew black fur.
Which of these best explains why the hair that grew back where the ice pack was placed was
black and not white?
F The genes for black hair were activated by specific temperatures.
G The white hair mutated to black hair as the rabbit's body temperature decreased.
H The coat color changed from white to black with the age of the rabbit.
3 White hair only grows during certain times of the year.
Answer:
F. The genes for black hair were activated by specific temperatures
Explanation:
The white hair only grows in cold temperatures. Just because they put an ice pack on the rabbit does not mean that its cold.
Rabbits regulate their body temperature by using their ears. A fever or a dip in body temperature could be indicated by extremely chilly or hot ears. Thus, option F is correct.
What are the adaptation rabbits have in Himalayan?In general, rabbits thrive in cooler climates. In the fall, rabbits stop shedding their fur and develop a thick coat of fur that keeps them warm in the winter. Low temperatures of 32 degrees don't really bother them.
Strong back legs offer rabbits the speed they need to run away from predators. Their feet have fur on the bottoms for warmth and strong claws for traction.

The figure presents a diagram of adding d T M P to a growing strand of D N A. A D N A template that consists of nine nucleotides is shown. Five nucleotides have already been added to the complementary strand that is growing from left to right along the template. The left end of the growing strand is labeled 5 prime, and the right end is labeled 3 prime. The left end of the template strand is labeled 3 prime, and the right end is labeled 5 prime. An incoming d T T P has three phosphate groups. Arrows indicate that the two outermost phosphate groups split off as the d T M P with the remaining phosphate group is about to join to the 3 prime end of the growing strand.
Figure 1. Model showing details of adding a deoxythymidine monophosphate (dTMP) nucleotide to a growing strand of DNA
The features of this model provide evidence for which explanation of why all growing strands are synthesized in a 5′ to 3′ direction?
A. The two strands need to be antiparallel to bond properly.
B. Thymine and adenine would not bond properly if the strand grew from 3′ to 5′.
C. The translation of mRNA occurs in the 5′ to 3′ direction; therefore, the growing DNA strand must also grow in the 5′ to 3′ direction.
D. The phosphate group, attached to the 5′ carbon of the dTMP, forms a covalent bond with the oxygen atom attached to the 3′ carbon of the growing strand.
Answer:
D - The phosphate group, attached to the 5′ carbon of the dTMP, forms a covalent bond with the oxygen atom attached to the 3′ carbon of the growing strand.
Explanation:
I got it checked and it was right
The feature of the model provides evidence in a 5′ to 3′ direction is the phosphate group, attached to the 5′ carbon of the dTMP, forms a covalent bond with the oxygen atom attached to the 3′ carbon of the growing strand. The correct option is D.
What are DNA bases?The sequence of DNA bases is referred to as the DNA sequence. RNA and DNA are both genetic elements composed of nucleic acids composed of deoxyribose acid, while RNA is composed of ribonucleic acid.
Both DNA and RNA have four bases that are linked together by a hydrogen bond. RNA has uracil in place of thymine, but DNA has timing and all other bases are the same.
Therefore, the correct option is D. The phosphate group, connected to the dTMP's 5′ carbon, creates a covalent bond with the oxygen atom associated with the developing strand's 3′ carbon.

Explanation:
Transcription is the process whereby a DNA template is used to form a mRNA molecule in the nucleus following the complementary base pairing rule. The complementary base pairing rule as postulated by Chargaff states that an Adenine base will always pair with Thymine (Uracil in RNA) while Guanine base will always pair with Cytosine i.e A-U, G-C.
N.B: Thymine in the DNA will yield Adenine in the mRNA while Adenine in the DNA will yield Uracil in the mRNA.
Hence, according to this question, the following DNA templates will be transcribed as follows:
1. CTGACTGACC to GACUGACUGG
2. AGCTCCGATC to UCGAGGCUAG
3. GCTAATCGAT to CGAUUAGCUA

A cell that has 6 chromosomes in the G2 phase will have how many sister chromatids during that same phase
Answer:
12 chromatids.
Explanation:
If a cell has 6 chromosomes in the G2 phase will have 12 sister chromatids during that same phase because replication of chromosomes occurs which produces two exact copies of each chromosomes. Then 6 chromatids are distributed in one daughter cell while the other 6 chromatids are distributed in other daughter cell and finally the cell division occurs.

PLZ HELP IM TAKING MY EXAM!! which of the following best explains the impact of mrna being double stranded before translation
Answer:
Impact of double-stranded mRNA before translation would inhibit the binding of tRNA to mRNA ti synthesize protein.
Explanation:
The mRNA is a molecule that, with the exception of viruses with double-stranded RNA, has only one chain. It is in charge of conducting to the ribosomes the sequence of nucleotides that makes possible the translation and the synthesis of proteins.
Once the ribosome translates the information of each codon of the mRNA, a transfer RNA (tRNA) molecule, with a complementary anticodon, provides the amino acid corresponding to the translated codon.
If the mRNA were double-stranded, the translation process would be altered, since binding of the tRNA with the amino acid it carries and mRNA codon would not be possible, as well as the protein synthesis.
