Describe the energy-releasing reaction shown in figure 1
idkeubeekenebekeenne
The energy-releasing reaction shown is the reaction of phosphorylation of fructose-6-phosphate to fructose-1, 6-bisphosphate.
Phosphorylation simply means the biochemical process that has to do with the addition of phosphate to an organic compound.
In this case, there's a reaction with fructose-6-phosphate to fructose-1, 6-bisphosphate.
Also, the ATP molecules have three high-energy phosphate groups which are vital for the transfer of one of its phosphate groups to fructose-6-phosphate and also provide energy to carry out the reaction.

If the newly-founded island population of moths in your GENETIC DRIFT Lab
simulation contains 30 (BB) black, 12 (Bb) grey, & 3 (bb) white moths, what is

population

Submit
Request Answer
Answer:
0.2 (or 20%)
Explanation:
The allele frequency can be calculated by counting how many times an allele appears in a population and then by dividing this number by the total number of alleles of the gene. In this case,
- Genotype BB = 30 moths >> 60 copies of the B allele
- Genotype Bb= 12 grey moths >> 12 copies of the B allele and 12 copies of the b allele
- Genotype bb= 3 white moths >> 6 copies of the b allele
The total number of copies of the gene is:
Dominant (B) allele = 60 (BB genotype) + 12 (Bb genotype) = 72 B alleles
Recessive (b) allele = 12 (Bb genotype) + 6 (bb genotype) = 18 B alleles
Then, 72 + 18 = 90 alleles
Allele frequencies:
Dominant (B) allele = 72/90 = 0.8 (or 80 %)
Recessive (b) allele = 18/90 = 0.2 (or 20%)
The frequency of the white allele b alleles for the moth-coloration gene in the population - 40%
The frequency of an allele can be calculated by dividing the number of times the allele of interest is observed in a population by the total number of copies of all the alleles at that particular genetic locus in the population
Total number of b alleles = number of alleles present in recessive bb + number of alleles present in heterozygotes Bb
Number of bb individuals = 3 Number of b alleles present in bb = 3 × 2 = 6 Number of Bb individuals = 12 Number of b alleles present in Bb = 12 × 1 = 12 Total number of b alleles = 6 + 12 = 18the frequency of an alele = 18/45
= 40%
Thus, the frequency of the white allele b alleles for the moth-coloration gene in the population - 40%

What do you think causes the cells to stop the repair process?
Answer:
reduced or poor blood supply
Explanation:
Since errors in the repair of DNA breaks can generate instability in the genome, repair of these breaks is a highly regulated process.
It is, therefore, essential the existence of control mechanisms that detect errors in this process and stop the cell cycle to allow the cell to repair the breaks, and if this is not possible, to eliminate the damaged cell.
A woman is 32 years old, after fiscussion it was noticed that she got her puberty at the age of 16 and has one children. How much polar bodies were formed at the age of 32?
Answer:
134
Explanation:
Polar bodies are formed each month after attaining puberty. Hence, total years of polar bodies formation are equal to the difference between the age of puberty till date.
Hence, total years of polar bodies formed = 32-16= 16
Hence, total number of polar bodies formed 16×12= 192
For one child absence of polar bodies formation = 15 months, where 9 months of gestation and 6 months of lactation.
So, for 1 child, it will be 15 x 1 = 15
Hence, net polar bodies formed in her body till date - 120 + 1 - 15 = 134
Hence, net polar bodies formed in her body till date 134
Which of the following describes how regions of phospholipids are arranged in the cell membrane?
Answer:
phospholipds are arranged in the phospholipid bilayer, inside the plasma membrane.
Explanation:
they have one hydrophilic head and two hydrophobic tails.
Phospholipids are amphipathic molecules that compose the cell bilayer membrane. Among the options, D is correct. Hydrophobic fatty acid regions face each other within the interior of the cell membrane.
-----------------------------------------------------
Two lipidic layers compose the cell membrane. There are also proteins and glucans incrusted in between.
The complex lipids that compose the membrane are amphipathic molecules. A phospholipid is composed of
two fatty acid chains ⇒ hydrophobic tails, glycerol and a phosphate group ⇒ hydrophilic heads negatively charged
Phospholipids are arranged as a bilayer. Their hydrophilic polar heads face the exterior and the interior of the cells, while their hydrophobic tails are hidden against each other, constituting the internal part of the membrane.
According to this framework, we can choose the best answer among the options,
A) Hydrophilic phosphate regions face each other within the interior of the cell membrane ⇒ Incorrect ⇒ Heads are not facing each other. They are in contact with the cell exterior and interior.
B) Hydrophilic phosphate regions are positioned toward nonpolar environments ⇒ Incorrect ⇒ Phosphate regions are in contact with water.
C) Hydrophobic fatty acid regions are positioned toward polar environments ⇒ Incorrect ⇒ tails can not be in contact with water.
D) Hydrophobic fatty acid regions face each other within the interior of the cell membrane ⇒ CORRECT.

Mutation 1 will cause translation to stop as there is presence of stop codon UAG, UAA, UGA.
What are the stop codons ?
In DNA or messenger RNA (mRNA), a stop codon is a sequence of three nucleotides (a trinucleotide) that tells the cell to stop making proteins. There are 64 distinct codons for trinucleotides. Three stop codons (UAA, UAG, and UGA) and 61 specific amino acids are included.Several codons, or triplet bases, make up the universal genetic code. To reduce coding errors, the standard code has developed over time. The genetic code is made up of 64 codons that are the result of the four bases in nucleic acids being permuted and combined.Since more than one codon can encode for a single amino acid, the genetic code is degenerate. Consequently, 61 of the 64 codons encode the 20 amino acids.The START and STOP codons, two punctuation marks in the genetic code, indicate the conclusion of protein synthesis in all organisms.Because it is the first codon in the transcribed mRNA to undergo translation, the codon AUG is referred to as the START codon. The amino acid methionine (Met) in eukaryotes and formyl methionine (f Met) in prokaryotes are both encoded by the most prevalent START codon, AUG. With the assistance of a few initiation factors, the t RNA recognizes the START codon AUG during protein synthesis and initiates mRNA translation.Amber (UAG), opal or umber (UGA), and ochre (UAA) are the three STOP codons. Charles Steinberg and Richard Epstein discovered Amber" or UAG and gave it the name "amber" after the German meaning of their friend Harris Bernstein's last name. In order to keep with the theme of "color names," the two remaining STOP codons were subsequently given the names "ochre" and "opal."To know more about codons check this:

How are ocean currents
similar to ocean waves in your own words?
Answer:
Swells are typically smooth waves, not choppy like wind waves. A swell is measured from the crest (top) to the trough (bottom). An ocean current is a continuous flow of water in the ocean. Some currents are surface currents while other currents are much deeper flowing hundreds of feet below the surface of the water.
