Why is humus important?
Sauron [17]

Answer:

D) It decreases water movement.

Explanation:

Humus is known as part of the soil formation. It is characterized by various qualities some of which include containing nutrients such as nitrogen. It is also characterized by its ability to retain water content or soil moisture. Humus is made from the decays of plants wastes such as leaves.

Hence, in this case, the correct answer is Humus is important because "It decreases water movement."

What is needed to convert PGA into G3P in the second step of the Calvin-Benson cycle? carbon atoms from carbon dioxide, RuBP, an
gtnhenbr [62]

PGA ( Phosphoglyceric acid) is a first stable product of photosynthesis which under goes reduction. Six molecules of 3-PGA is reduced to six molecules of a chemical compound called glyceraldehyde 3-phosphate (G3P). In this conversion; six molecules of both ATP and NADPH are used. In this reduction reaction, there is gain of electrons by 3-PGA. NADPH is oxidized to NADP+ to give elections and energy is given by ATP.

A population of 100 tigers has 30 with horizontal stripes. Using pedigrees, you ascertain that horizontal striping is caused by
bixtya [17]

Assuming that this population is in Hardy-Weinberg equilibrium, we can sayt that  <em>the</em><em> probability</em><em> that, given enough time, all tigers in the population will have horizontal stripes is</em><em> 30% = 0.3.</em>

--------------------------

<u>Available data:</u>

  • Population size, N = 100 tigers
  • Number of Tigers with horizontal stripes = 30
  • Horizontal stripes is caused by an autosomal recessive mutation.

We need to know the probability that all tigers in the population will have horizontal stripes, which is the recessive phenotype.

We assume that the population is in Hardy-Weinberg equilibrium, so there should be no evolution.

Since the population is in H-W equilibrium, the allelic, genotypic and phenotypic frequencies will remain the same generation after generation.

Now, we will calculate the allelic and genotypic frequencies of horizontal striped individuals in the population.

There are 100 individuals, and only 30 have horizontal stripes.

So, the phenotypic frequency, F(HS) is 30/100 = 0.3 = 30%

Since this is a recessive phenotype, this value equals the genotypic frequency, F(hh) = 30%

Finally, we can get the allelic frequency by taking the square root of this value.

F(hh) = q² = 0.3

f(h) = q = √0.3 = 0.55 = 55%

According to these calcs, the probability for the fixation of the recessive allele is 55%, and the probability that all individuals express the recessive horizontal stripes phenotype is 30%.
