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:
The three basic types of adaptations, based on how the genetic changes are expressed, are structural, physiological and behavioral adaptations. Most organisms have combinations of all these types

4. The expression of beta-galactosidase requires the induction of operons by removal of _repressors_____________.
5. Unlike DNA synthesis, RNA synthesis does not require ___primers___________.
6. ___consensus sequences___________ are deduced by comparing many related DNA sequences.
Answer:
b. Hydrogen-carbon
Explanation:
Triglycerides, also called fats are fatty acid esters of glycerol. One molecule of triglyceride consists of three fatty acids linked to one glycerol by ester linkages. Fatty acids are hydrocarbon derivatives with a long hydrocarbon chain in which carbon atoms are bonded to hydrogen atoms by covalent bonds. The carbon-hydrogen bond is one of the bonds with high energy levels. Therefore, the energy of triglycerides is stored in carbon-hydrogen bonds of hydrocarbon chains of fatty acids.
It is hard to understand this question but ill give you my best answer. The hearts level of organisation to cells is immense, the heart pumps blood to every cell in the body (so they can respire) through a system of Arteries, veins and capillaries. The blood is pushed by the force of the heart through the arteries, the main (and largest) tubes for transportation to segments of the body further away from the heart. This goes into a smaller system of veins that brake off into a tree kind of pattern to reach every cell. These later brake off into the capillaries that have walls only 1 cell thick. This is how blood is transported to each cell that requires energy and oxygen to respire.
