to restore environmental vitality to land degraded from mining
100% correct, I just took the quiz
Answer:
It is understood that not all them have the same function because the shape dictates function.
Explanation:y
All the amino acids of the proteins are categorized under three groups, because side groups of each amino acids differ from others.
It should be noted that the sequence of amino acids in a protein is based on the nucleotides sequence in the gene that is encoding it. This now determines the function of the protein.
Answer:
The correct answer would be -
1- YR, Yr, yR and yr.
2. Yr, yR
3. YR, yr
4. YR, Yr, yR & yr
Explanation:
A mature male or female haploid germ cell that fuses with another gamete of the opposite sex during the process of fertilization to make a zygote in sexual reproduction.
The law of Independent Assortment presented by Mendel says that alleles for different traits are passed and assort independently of one another in the gametes.
1. If Y and R on different chromosomes then they will produce four gametes and assort independently - YR, Yr, yR & yr.
2) If Y and R on the same chromosomes and no crossing over occurs then they will produce only two gametes as Y and R will not come together - Yr & yR.
3). if dominant Y and recessive r are on the same chromosome, no crossing over then only two gametes will form as Y and r will not assort together - YR & yr.
4). if dominant Y and R are on the same chromosome, 50% crossing over produces 4 types of gametes, YR, Yr, yR & yr.
Answer:
A quarter (25%) of the individuals that carry at least one s allele are homozygotes.
Explanation:
Knowing the frequency of s, we can find the frequency of both alleles, because:
Now, if the population of guppies is at Hardy-Weinberg equilibrium, we can find how many heterozygotes and homozygotes are, like this:
We know that:
So, we need to know what is the frequency of guppies Ss (2pq) and ss (s2):
Finally, to find the fraction of homozygotes (ss) of the individuals that carry at least one s allele, we need to divide the frecuency of homozygotes ss into the frequency of heterozygotes Ss:
0.25 or 25% of the guppies carring the allele s are homozygotes.
