Answer:
B. The cytoplasm
Explanation:
One of the main responsibilities of the cytoplasm is to control all metabolic activity that takes place within the cell.
If a substitution changes the amino acid to a “stop,” it's called a NONSENSE mutation. frameshift, missense, silent or nonsense (hint: deletion or insertion will always be frameshift). Sickel cell anemia is the result of a type of mutation in the gene that codes for part of the hemoglobin molecule.
Answer:
The answer is A.
Explanation:
Plant blindness refers to "the inability to see or notice the plants in one's own environment." The term plant blindness was coined twenty years ago by Elizabeth Schussler and James Wandersee who are botanists. Plant blindness results in "the inability to recognize the importance of plants in the biosphere and in human affairs." It is also the reason why people have a tendency of ranking “plants as inferior to animals”. Therefore, plants tend to receive limited care and upkeep. It is important to recognize plant blindness so that more intentional care can be given to preserving our plant species and ensure their survival and ability to thrive.
Answer:
Explanation:
<em>Let the ability to break down the red color in beets be represented by the allele </em><em>B</em><em>. The inability would be represented by the allele </em><em>b</em><em>.</em>
A nonsecretor's genotype would be BB or Bb while a secretor's genotype would be bb.
A nonsecretor woman with a secretor father would be a carrier with genotype Bb. A nonsecretor man who in a previous marriage had a secretor daughter would also be a carrier with genotype Bb. If the two marries:
<em>Bb x Bb</em>
<em> BB 2Bb bb</em>
1.
(a) probability of their first child will be a secretor girl = probability of having a girl and being a secretor.
Probability of having a girl = 1/2
Probability of being a secretor = 1/4
<em>probability of their first child will be a secretor girl</em> = 1/2 x 1/4 = 1/8
(b) Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor.
Probability of having a girl = 1/2
Probability of being a nonsecretor = 3/4
<em>Probability of their first child being a nonsecretor girl = probability of having a girl and being a nonsecretor</em> = 1/2 x 3/4 = 3/8
2. <em>Probability that their first two children will be nonsecretors of either sex = probability of their first being a nonsecretor and of either sex and probability of their second being a nonsecretor and of either sex.</em>
= 3/4 x 3/4 = 9/16
