Answer:
<em> a) There is a 25% chance that their next child will be Rh-.</em>
<em>b) There is a 3/8 chance for a Rh+ girl</em>
Explanation:
As we know from the question that Rh is a dominant gene. A person having only one allele for the gene will show its effect as it is the dominant character.
This means that for a person to lack the Rh factor, it shall not have any allele with the Rh factor.
To illustrate the result, lets draw a punnet square:
Rh+ Rh-
Rh+ Rh+/Rh+ Rh+/Rh-
Rh- Rh+/Rh- Rh-/Rh-
For the probability for it to be a girl, we know that there are 50-50 chances for the next baby to be a boy or a girl. The chance of being Rh+ are 75% for the next baby.
Hence,
3/4 multiplied by 1/2 is 3/8 ,which is the chance for the next baby to be a girl with Rh+ factor.
Answer:
Breast, Colorectal and Lung cancers are the most common. Smoking and Tobacco. Diet and Physical Activity. Sun and Other Types of Radiation are the most common causes of cancer.
Explanation:
I think this is what you need, if not could clarify a bit more in the question.
The answer is D I believe because their cancer is no longer spreading
Answer:
A. maintenance of axons is not a cellular activity associated with microtubules.
Explanation:
Microtubules are hollow, bead-like, tiny tubular structure that helps cells maintain its shapes. Together with microfilaments and intermediate filaments, they form part of the cell's cytoskeleton. Microtubules also contributes to the cell movement or cytokinesis that includes muscle contractions in muscle cells. Microtubules also replicated chromosomes to opposite ends of a cell during cell division. Microtubules also contribute to the parts of the cell that help it move and are structural elements of cilia, centrioles and flagella. A bundle of microtubules makes up an axonemal structure of cilia and flagella.
