Answer:
25%
Explanation:
Here's an example: two chickens have the phenotype of white feathers and brown feathers. What percentage of the chicks will have the recessive color? First, you have to see the parents' phenotypes. Draw a punnet square. Put one of the parent's phenotypes (w and B) on the top, and the other parent's (w and B) on the right side going down. Whichever trait is dominant (brown) MUST be capitalized. Then, cross the two parents. first box on the top left would read 'ww.' The one below it is 'Bw' (put the dominant first). The right top is 'Bw' and the one below it is 'BB'. So if there were 4 offspring, these would be their genotypes: 'ww', 'Bw', 'Bw', and 'BB'. The only offspring that would have the recessive trait is the 'ww' child, because dominant overpowers recessive. So 25% would have the recessive trait and 75% would have the dominant trait.
The most observable difference is the way in which cytokinesis occurs. In plants a new cell wall is fashioned between the new daughter cells, while in animal cells the cell membrane constricts to pinch the parent cell into daughter cells.
Cells are the smallest unit of life
Answer:
B)
Explanation:
Histology is important in the health sciences as it studies the structure and function of tissues and cells.
While studying about how tissues and cells are working helps to recognize different diseases. It can also helps to identify the cause of such diseases and treatment of diseases.
Hence, the correct answer is "B)."
<h3>Cofactors</h3>
Explanation:
Enzymes are biochemicals which catalyze a biochemical reaction taking place in the body by reducing the activation energy barriers and changing the substrate molecules to products.
The active sites of enzymes first binds to the substrate and forms an enzyme-substrate complex.
An enzyme can work actively only with the help of helper molecules called co-factors and co-enzymes.
Co-factors are non-protein inorganic ions like iron, magnesium which helps the catalyze chemical reactions.
Cofactors are bound tightly with the active sites of the enzymes and also contribute for the structural integrity and stability of the enzyme
