Convection keeps the earths surface warm
I believe the answer would be D, plant. Plant cell walls appear as tiny little boxes that are given their shape by two chemicals: cellulose and lignin. Cellulose is the basic structural component of plant cell walls and is also found in vegetable matter, cotton and wood. High amounts of cellulose are consumed by herbivores, usually with the assistance of bacteria.
Answer: Option b
Explanation:In chemistry,
before any reaction would occurs, reactat must be able to overcome some certain amount of energy which is called the activation. The activation energy is usually the heat that is suppled.it is also refered to as the minimum energy needed before any reaction can take place. For reaction to take place, there must be an equilibrium( at constant temperature and pressure.
Answer:
Explanation:
the purple allele (C) is dominant to the pink allele (c).
The frequency of C represents p while that of c represent q. Using the formula p+q= 1
The proportion of pink flower is 153/1000 = 0.153. This is also the frequency of the genotype cc (q^2).
Thud to find q which is the frequency of the c allele,
q = √0.153
q = 0.3912
From the formula p +q = 1 we can find p p = 1 - 0.3912
p which is the frequency of the C allele
p = 0.6088.
B. the proportion of all purple flowering plants that are heterozygotes and homozygotes is 847 / 1000 = 0.847
