Aphotic zone of a body of water refers to the part where almost no sunlight. With this condition of water, marine life is limited to species who does not light for survival. The aphotic area also is the basin of the dead organism that submerges from the photic part. Temperatures at these areas are also low.

When we look at a leaf, we see the colors of light that are reflected off its surface. How does this explain the relatively low
anastassius [24]
Oxygen is produced in the light stage of photosynthesis at Photosystem 2 and results from the splitting of water. Chlorophyll does not absorb green light so in green light there will be less water split and so less oxygen is produced.so thats how we know the reason why a leaf is the color that it is. basically it is because of chlorophyll.

Hope this helps.

Two forces F1 and F2 act on a particle. As a result the speed of the particle increases. Which one of the following is NOT possi
ddd [48]

Answer:

Option D, The work done by each force is negative

Explanation:

When both the forces are negative, then irrespective of which force is large or small, the net force will definitely negative. A negative force indicates reduction in kinetic energy of particle. Since mass is constant , it is the speed which reduces and produces negative work. Reduction in speed is contrasting to the statement give in the question. Hence, option D is not possible.

Black coat color in horses is conferred by the presence of a dominant B allele. Chestnut horses are genotype bb. A population of
AysviL [449]

Answer:

Frequency of B allele is 0.6681

Explanation:

If p represents the frequency of dominant allele and q represents the frequency of  recessive allele, according to Hardy-Weinberg equilibrium:

p + q = 1

p² + 2pq + q² = 1

where p² = frequency of homozygous dominant genotype

q² = frequency of homozygous recessive genotype

2pq = frequency of heterozygous genotype

Given that number of recessive chestnut horse = 28

Total horses = 226 + 28 = 254

frequency of b² genotype = 28/254 = 0.1102

frequency of recessive b allele = √0.1102 = 0.3319

So, frequency of B allele =

1 - 0.3319 = 0.6681

Hence frequency of B allele is 0.6681
