I'm not sure if this is correct, but the answer I got was: endoplasmic reticulum.
I hope this helps, and have a good night! :D
Answer:
C. 1/4
Explanation:
Let's assume that the allele for the spotted coat is "S" and the one for the even coat is "s". The allele "L" gives short horns while the recessive allele "l" imparts long horns. The genotype of the cattle heterozygous for both traits would be SsLl. A cross between two heterozygous cattle would produce progeny in following phenotype ratio=
9 spotted coat and short horns: 3 even coat and short horns: 3 spotted coat and long horns: 1 even coat and long horns.
Therefore, the proportion of the progeny with long horns = 4/16= 1/4
Answer:
Cellular respiration that proceeds in the absence of oxygen is anaerobic respiration. Cellular respiration that proceeds in the presence of oxygen is aerobic respiration.
<span>The three main reasons why cell division is important in organisms are reproduction, repair and growth, Cell division is necessary in order for life to continue.</span>
New, more adaptable species flourish, replacing the extinct species.
The selection pressures before the extinction tend to favor a certain type of organism and the sudden shift in conditions help others move up the food chain.
