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.
<em>Electron microscope </em><em>is most likely to be used to produce a clear image of very tiny structures inside a cell</em>

The electron microscope is a kind of magnifying instrument that utilises electrons to make a picture of the objective. It has a lot higher amplification or settling power than a typical light microscope. The tiny structures inside the cell are easily visible under the electron microscope.

Answer:
C - Contains the embryonic disk
Explanation:
After an egg is fertilized, it begins to divide into smaller cells, from the 1 cell stage, to 2, to 4 and so on. Then, on the third day, the cells fall within 16-200 cells and it is then called a <em>morula</em>.
On the fifth day, the morula becomes a ball of calls which is now differentiated into an <em>inner cell mass and a trophectoderm</em>. The inner cell mass becomes the <em>embryo</em> as development goes on and the trophectoderm, becomes the <em>placenta</em>.
As development goes on further, the floor of the amniotic cavity is formed by the embryonic disk, a layer of prismatic cells derived from the inner cell mass.
The embryonic disc develops into 3 layers:
There is a major differentiation of cells which gives a template for the origin of development of specific organs of the embryo.
