Answer:
True
Explanation:
The lumen of a blood vessel helps determine blood pressure as blood flows through lumen and bp is measured in the lumen of artery
GLUCOSE IS CONVERTED INTO CELLULOSE FOR MAKING CELL WALLS. GLUCOSE IS COMBINED WITH NITRATES (COLLECTED FROM THE SOIL) TO MAKE AMINO ACIDS, WHICH ARE THEN MADE INTO PROTEINS. GLUCOSE IS TURNED INTO LIPIDS FOR STORING IN SEEDS.
Explanation:
Membrane proteins perform a variety of functions vital to the survival of organisms: Membrane receptor proteins relay signals between the cell's internal and external environments. Transport proteins move molecules and ions across the membrane. ... Cell adhesion molecules allow cells to identify each other and interact.
Answer:
Higher oxygen levels means animals can grow larger and still maintain the supply of oxygen to their muscles. Falkowski and colleagues calculated fluctuations in the atmosphere's oxygen levels from cores of deep-sea rocks dating back 205 million years.
Answer:

Explanation:
Given frequency of the two alleles i.e "B" and "b" are equal .
As per Hardy–Weinberg equilibrium, sum of frequency of the two alleles is equal to one.
i.e 
Since 
and
will be equal to 0.5
Frequency of genotype "BB"

Frequency of genotype "bb"

As per second equation of Hardy–Weinberg equilibrium,

Substituting the values of p and q in above equation we get -

Red beetles have genotype BB and Bb
number of red beetles with genotype (BB)

number of red beetles with genotype (BB)

Total red beetles

Frequency of red beetles
