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.
Answer:
Option B, haploid with two copy of each gene
Explanation:
The stage of Meiosis II, starts with the pro phase II stage. In this stage the genetic material consists of haploid cells. The cells that enter into meiosisII are the ones which are formed by the end of meiosis I and these are haploid cells that have not copied their DNA which means they have only one chromosome form each homologue pair and two sister chromatids. Thus in Meiosis I haploid cells are formed with non-duplicated chromosome which are found at the first stage of meiosis II i.e prophase II
Thus, Option B is correct
Answer:
Yes,
It is considered equilibrium or homeostatis.
Explanation:
example: plankton as a producer, minnows and young fish eat the plankton. Larger game fish eat the littler fish. Humans and other animals consume larger fish. Animals die off, bacterial decay are washed into water to start it all over again.
You can tell the difference because one deals with sugar and energy storage like lipids but lipids are fats or fatty acids like unsaturated and saturated fats the unsaturated fats are good for you and has the most energy source.
Answer:
Apoptosis (programed cell death)
Explanation:
Apoptosis is a type of controlled cell death. It happens throughout development when cells have to be removed. It also gets rid of diseased cells, such as those that are potentially cancerous, or those infected with a pathogen, for example.
