. In this example, red flower coloring is dominant to white, and your population of 200 plants has 150 plants with red flowers.

AnnyKZ [126]

Answer:

a) The allele frequencies are - $p= 0.8660\\q= 0.134$

b) Genotype frequencies for this population- $p^2=0.75, q^2= 0.0179, 2pq = 0.2321$

Explanation:

Given ,

Red color of flower is dominant to white color flower

Let "R" represents allele for red color and "r" represents allele for white color

out of $200$ flower, $150$ are red flowers.

So the frequency of red flowers with genotype "RR" is equal to

$p^{2} = \frac{150}{200} \\p^{2} =0.75$

As per hardy Weinberg's I equilibrium equation -

$p+q=1\\p=\sqrt{p^2} \\p=\sqrt{0.75} \\p= 0.8660\\q= 1-p\\q= 1-0.8660\\q = 0.134$

a) The allele frequencies are - $p= 0.8660\\q= 0.134$

Frequency of genotype "rr" i.e homozygous recessive white flower is

$q^{2} \\0.134^2\\q^2 = 0.0179\\$

Substituting the values of $p^2$ and $q^2$ , in below equation, we get -

$p^2+2pq+q^2=1\\2pq= 1-p^2-q^2\\2pq= 1-0.75-0.0179\\2pq=0.2321$

b) Genotype frequencies for this population- $p^2=0.75, q^2= 0.0179, 2pq = 0.2321$

A Viceroy caterpillar feeds on a leaf. One day's feeding consumes 1000 calories worth of leaves. 50% of the calories are lost in

KonstantinChe [14]

Answer: 170 calories.

Explanation:

The Viceroy caterpillars feeds on the green plants and trees for its survival. The total energy that is incorporated in the body of the caterpillar is used in cellular respiration, faces and rest amount of the energy left is used as biomass by the caterpillar each day.

The total energy is 1000 calories, 50% of this energy is 500 calories which is released out of the body through faces. Rest 33% of total energy( 330 calories) is used in cellular respiration.

The rest amount of energy that is available is 170 calories.

Describe what happens as you work your way down the taxonomy ladder?

erica [24]

Answer:

As we move down the taxonomy ladder the group gets smaller and more specific.

Explanation:

Taxonomy hierarchy is the classification system of organism developed by the Linnaeus.
Linnaeus gave every organism its genus and species, forming a binomial nomenclature.
The taxonomy ladder comprises of 8 ranks (domain, kingdom, phylum, class, order, family, genus, and species) that include the section from general to specific ones.
So as we move down in the ladder system we can find more specific species in its classification.

Select all that apply. For the photosynthesis process to occur, a plant needs _____. sunlight chlorophyll nitrogen carbon dioxid

Volgvan

The answer is sunlight, chlorophyll, carbon dioxide and water.

In the photosynthesis plants use sunlight as an energy and convert it into chemical energy stored in carbohydrates. Carbon dioxide and water are used for carbohydrate synthesis. This process occurs in the chloroplasts containing chlorophyll, which is necessary for absorbing energy from sunlight.
