Answer:
a, 8
b, 3
Explanation:
If the pedigree you are referring to is the one that is attached then the answer would be:
A pedigree shows how a trait is passed on throughout generations. Like it says in the question, the squares represent males. If the square isn't shaded in, then that means they are unaffected by the trait or normal. If it is shaded, they are affected.
All you need to do for the first question is count the number of squares you see in the whole pedigree. In this case, there are 8.
The second one is asking how many are affected, or have hemophilia. You need to count the number of squares that are shaded in. In the pedigree, we see 3.
Answer: Mitochondria
Explanation:
The power house of the cell is known as Mitochondria. The energy that is required by the body is provided by mitochondria.
The hydrolysis of the ATP takes place in which it is converted into ADP and Pi and some amount of energy is released.
This energy is used by the body for the various types of metabolic activities. The site of ATP formation is mitochondria.
Answer:
1 out of 4
or
25%
Explanation:
First we draw a Punnett Square for this:
R r
R RR Rr
r Rr rr
So here we have the following genotypes possible for this cross:
RR = homozygous dominant
Rr = heterozygous dominant
rr = homozygous recessive
As you can see out of the four (4) possible outcomes, one (1) of them is rr. So the probability is 1 out of 4 chances or 25%.
The study of fossils shows that the eukaryotic cells have been evolved from the prokaryotic cells. The endosymbiotic theory has been used to study the evolution of eukaryotic cells.
The endosymbiotic theory states that:
- Endosymbiotic theory is also referred to as the theory of symbiogenesis. The theory explains the evolution of eukaryotic cells from prokaryotic cells.
- The theory explains the presence of chloroplasts and mitochondria, and how these organelles form the eukaryotic cells. The theory explains the origin of mitochondria in animal cells and chloroplasts in plant cells.
Thus, the endosymbiotic theory defines the development of eukaryotic cells from the prokaryotic cells.
