Complete question:
Punnet squares for genes found in sex chromosomes are unique in that the pattern of inheritance of these traits is gender-specific. For example, examine the following Punnet square for color blindness, a trait found in the X chromosome (Y chromosome carry only a few genes but they do not possess enough coded information to initiate the development of the male).
Xcb represents the X chromosome carrying the color blindness trait. The allele for color blindness is recessive to the normal form of the gene (X).
Punnet square:
Mother
Xcb X
Father X X Xcb X X
Y Xcb Y X Y
Do male and female offspring possess the same likelihood of carrying the colorblindness trait in their genotype?
Answer:
<em>YES. Male and female offspring </em><u><em>will have the same likelihood</em></u><em> of carrying the colorblindness trait in their genotype. </em>
Explanation:
Due to technical problems, you will find the complete explanation in the artached files.
The right answer is a. synthesis of energy-rich sugars.
With chlorophyll, green plants absorb the light energy needed to synthesize an organic chemical species, glucose C6H1206, from carbon dioxide and water vapor. Each billion tons of the carbon element C are fixed by the green plants in the form of glucose. The reaction, called photosynthesis, also produces dioxygen and helps to regenerate this chemical species necessary for the breathing of living beings.
Answer:
b. laminar flow
the reynold number is 1329.26
Explanation:
Re = (V x D x ρ)/ η
where,
V = mean velocity = 15.9 cm/s = 0.159m/s
D = vessel diameter = 2.15cm = 0.0215m
ρ = blood density = 1050 kg/m3 = 0.00105 kg/cm3
η = dynamic viscousity= 2.70 × 10-3 Pa·s = 2.70 × 10-3 kg/m-s
applying the formular to calculate for reynolds number, Re =
Re = (V x D x ρ)/ η
=(0.159 x 0.0215 x 1050) / 2.70 × 10-3
=3.589/0.0027 = 1329.26
the Reynolds number for the blood leaving the heart through the aorta if the diameter of the aorta is 2.15 cm and the blood has a dynamic viscosity of 2.70 × 10-3 Pa·s, a density of 1050 kg/m3, and travels at a mean fluid velocity of 15.9 cm/s is 1329.26
which flow through the aorta in a Laminar flow
Note that
a) turbulen= Re >4000
b) laminar= Re <2300
c) transitioning between laminar and turbulen= Re between 2100 and 4000
Answer:
B
Explanation:
To begin with, it is clear that this cell has a cell wall (the rigid cubicle like structure around the cell). Only plants (that can carry out photosynthesis) have a cell wall. Secondly, one can view the chloroplasts in the cell (the organelles with green pigments inside). This is where photosynthesis takes place in the cell.
