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:
The membranes of winter wheat are able to remain fluid when it is extremely cold by Increasing the percentage of unsaturated phospholipids in the membrane
Explanation:
In winter ,cell membrane can freeze but presence of unsaturated fatty acid make it movable because they have Double bond which make them unable to pack tightly due to kinks.
The correct answer is B)attachment of microtubules to kinetochores.
Mitosis is a process of cell division in which newly replicated chromosomes separated equally into two parts of a cell. During late prophase of the mitotic cycle, the nuclear envelope breaks down or disappear. This allows attachment of the microtubules to the kinetochores of sister chromatids at the metaphase-anaphase transition. The attachment finally leads to the formation of two daughter cells.
Answer:
An inward structure that gives every cell it's unique shape, is basically a <u>Cytoskeleton</u>, and the auxiliary steel radiates are the reinforcement for buildings, bridges, or homes.
