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:
Organelles
Explanation:
Living cells of organisms contain structures within them that perform specific functions for the cell. These structures are called ORGANELLES. Organelles are organ-like structures that are specific about their function in a cell.
Both the cells of prokaryotes and eukaryotes possess organelles, however, the organelles in eukaryotes are bounded by a membrane e.g mitochondrion, chloroplast etc. while those of prokaryotic cells are not bounded by a membrane.
The organelles inside a cell can be seen with the aid of an electron microscope. Examples of organelles are chloroplast (functions in photosynthesis), mitochondria (functions in production and storage of cellular energy), ribosome (functions in protein synthesis) etc.
Only prokaryotes (the archaea<span> and the </span>bacteria<span>) reproduce asexually through binary fission. Eukaryotes (such as protists and unicellular fungi) reproduce by mitosis; most of these are also capable of sexual reproduction</span>
