1) How to use pedigrees:
They are diagrams in which people are represented by symbols. Circles
represent female and squares represent males.
The bottom line represents the offspring of the couple above it.
Dark symbols are used to indicate someone who is affected with a
genetic condition.
Not colored symbols indicate someone who is NOT affected.
A heterozygote carrier.can be represented as grey color.
2) How traits are inherited:
Humans have 23 pairs of chromosomes (46 chromosomes) because 23 chromosomes are inherited from the father and the other 23 come from the mother.
With 23 sets, you have two copies of each gene. This copies can be different or the same and based on that there could be different traits for the same gene like black, brown or blond hair.
Answer:
O 9.25
Explanation:
The following mathematical equation is given in this question:
5x + 2y = 20
Using this equation, we're asked to find the value of y when x = 0.3. Hence, we substitute 0.3 for x in the equation as follows:
5x + 2y = 20
5 (0.3) + 2y = 20
1.5 + 2y = 20
Collect like terms
2y = 20 - 1.5
2y = 18.5
Divide both sides by 2
y = 18.5/2
y = 9.25
Therefore, y = 9.25 when x = 0.3
Answer:
Omega-3 Fatty Acids

Explanation:
during mitosis the cell divides into two identical daughter cells!
A white blood cell engulfing foreign materials is more likely to carry out Endocytosis.
Explanation:
- Endocytosis is the process by which a cell takes up a macromolecule into is cytoplasm by forming a vessicle.
- In the question two cases are given, both the cases involve the formation of membrane bound vessicle but in different ways.
- The excretion of hormones involves the movement of molecule outside the cytoplasm. This process is exocytosis.
- The engulfment of an antigen by WBC involves taking up of molecule within the cell so that it can be killed and digested. Thus in this case Endocytosis is more likely to occur..
