2. What nutrients do you need to stay alive? How do you obtain them?

NNADVOKAT [17]

Answer:

Explanation:Plants and other autotrophs absorb nutrients from soil and water. Autotrophs are organisms that can make their own food. The most important nutrients they need are carbon, hydrogen, and oxygen. Other nutrients needed by plants are nitrogen, phosphorous, potassium, calcium, magnesium, and sulfur.

Plants take up carbon dioxide from the atmosphere and fix the molecules into organic compounds. This is why forests are recognized as significant carbon sinks because they sequester carbon from the atmosphere. Therefore, deforestation is a big contributor to an increase in atmospheric carbon dioxide. The other contributor to an increase of the greenhouse gas is rapid industrialization whereby industries emit carbon dioxide as a pollutant.

In fruit flies, L = long wings and I = short wings. When a long winged fly is crossed with a short winged fly, the off spring ex

stellarik [79]

Answer:

Genotype of long winged fly is Ll

Genotype of short winged fly is ll

Explanation:

Given

Allele for long wing trait is "L"

Allele for short wing trait is "l"

When a long winged fly is crossed with a short winged fly, half of the offspring have long wings and other half have short wings as the ratio is $1:1$

Let us say that the genotype of long winged fly is Ll

and the genotype of short winged fly is ll

The cross between the two will produce following offspring

Ll * ll

Ll, Ll, ll, ll

Out of four off spring two have long wings (Ll)

and the other two have short wings (ll)

Thus the ration of long to short wing offspring is $2:2$ i.e $1:1$

Assuming that the affection is a recessive trait caused by a single diallelic gene, the percentage of the population that possess the heter0zyg0us advantage is 32%.

<h3>Available data</h3>

1000 of African people population
4% of the population is born with sickle cell anemia

100% of the population -------------------- 1000 individuals

4% of the population with anemia------- X = (4 x 1000) / 100 = 40

0.04 is the frequency of individuals with sickle cell anemia.

Assuming that the affection is a recessive trait caused by a single diallelic gene, we can get the allelic frequency as follows.

The genotypic frequency is q² = 0.04

The allelic frequency is q = √0.04 = 0.2

Having the recessive allelic frequency, we can get the dominant allelic frequency, by clearing the following equation,

p + q = 1

p = 1 - q

p = 1 - 0.2

p = 0.8

So, the allelic frequencies are

p = 0.8

q = 0.2

To get the heter0zyg0us frequency, we just need to replace the values

2pq = 2 x p x q = 2 x 0.2 x 0.8 = 0.32

The frequency of the heter0zyg0us genotype is 0.32 = 32%.

32% of the population possess the heterozygous advantage.
