Answer:
Predict the possible genotypes and phenotypes percentages for the
offspring produced from the cross below if albinism is recessive in
humans. Albino male x Heterozygous female
aa X Aa = Aa, aa, Aa, aa
Explanation:
From the crossing above, it is right to say that albinism and non-albinism occur in a 50-50 ratio i.e 50% each. The genotype shows that there is 50% homozygous recessive albinism while there is also 50% heterozygous non-albinism. The phenotype reflects that there no dominance of albinism or non-albinism, they both share equal phenotypic characteristics
Answer:
C, B, A, D
Explanation:
The images in this question is portraying the stages involved in MITOSIS, which is a kind of cell division that forms two genetically identical daughter cells. The four stages of mitosis represented in the image are as follows: interphase, prophase, metaphase, and anaphase
- INTERPHASE: This stage is regarded as the resting stage of the cell. The chromosomes are found to be supercooled together as chromatins as seen in image C.
- PROPHASE: In the prophase stage, the chromosomes become condensed and more visible as seen in image B.
- METAPHASE: In the metaphase stage, the chromosomes align at the equator of the cell in order to be pulled apart by microtubules as seen in image A.
- ANAPHASE: In the Anaphase stage, the chromosomes are pulled apart into opposite poles of the cell as depicted in image D.
Answer:
Decreased breathing (a) is not a symptom of ketoacidosis.
Explanation:
Ketoacidosis is a condition involving the levated production of ketones in the organism, usually as a consequence of type 1 diabetes.
The build up of ketones in the blood is mostly due to the breakdown of fatty acids by the body to acquire energy. Since ketone is an organic acid, its high levels decrease blood pH leading to several symptoms.
Frequent urination (polurya), fruity odor to breath, dehydratation and electrolyte imbalance are some of the symptoms. Decreased breathing rate is not a symptom, actually, ketoacidosis leads to rapid breathing.
Increasing the rate of breathing reduces the amount of CO₂ in the blood, which increases its pH making it less acidic.
