If 4,000 units of energy are available in the producer level ,about how much would be available to the tertiary consumers?

assume that Q is the frequency of the recessive gene R expressing y color piece and that in a isolated area 68 plants with red a

Oksi-84 [34.3K]

Explanation:

q= 0.566

Homozygous individuals have two copies of the same allele for a gene. Homozygous dominant individuals carry two copies of the dominant allele, while homozygous recessive individuals carry two copies of the recessive allele.

Further Explanation:

DNA sets contain genes that may have different forms named alleles. DNA, which is the genotype, is transcribed into mRNA and later translated into amino acids which are connected together by rRNA to form proteins which constitute the phenotype of an organism. DNA sequence mutations form new allles, impacting the resulting mRNA, and thus the encoded protein. Within species, there may be adaptation, along with genetic drift, preferential breeding, and natural selection.

Within a population certain alleles are fixed over time. In Hardy-Weinberg-allelic frequencies, the equilibrium for a particular gene is not undergoing evolution, being stable for several generations. Mutations, during this time affect the corresponding mRNA, and thus the encoded protein. Evolution may occur within populations, along with genetic drift, selective mating, and natural selection.

Over time, certain alleles become fixed within a population. Equilibrium for a specific gene is not undergoing evolution in Hardy-Weinberg-allelic frequencies are stable for several generations. During this period, mutations do not occur within the population, this is shown as

$p^{2} + 2pq +q^{2} = 1$ ....(eqn i)

where...

p represents the dominant allele frequency

q represents the frequency of the recessive allele

q^2 = the genotypic frequency of the homozygous recessive

p^2= the genotypic frequency of the homozygous dominant

2pq= frequency of the heterozygous genotype

and simply p+q= 1 ...(eqn ii)

The allelic freq. of r is denoted by q and the allelic frequency, R is denoted by p...

The total number of individuals= 32+ 68= 100

Thus q= √ $q^{2}$ = homozygous recessive individuals (white flowers)

Since there are 32 white flowering plants , freq rr= 32÷ 100= 0.32

...thus $q^{2}$ =0.32

and q= √ $q^{2}$ = √0.32= 0.566

In a dihybrid cross of two heterozygous individuals, you expect a 9:3:3:1 phenotypic ratio in the offspring, but observe a ratio

almond37 [142]

Answer:

e. Epistatic interaction of the two genes

Explanation:

The 9:7 ratio is typical of the Duplicate Recessive Epistasis.

The expected phenotypic ratiio of the offsrping of a dihybrid cross is:

9 A_B_

3 A_bb

3 aaB_

1 aabb

In the Duplicate Recessive Epistasis, the A_bb, aaB_ and aabb individuals all have the same phenotype, making for the ratio 9:7. What those three genotypes have in common is that in all of them at least one of the two genes is homozygous recessive (either aa or bb).

This usually happens one the products of genes A and B are enzymes of the same metabolic pathway.

Whenever both A and B are present, the pathway can produce the final product and a certain phenotype. However, if any of the dominant alleles is missing, the enzyme is not produced and therefore the final product of pathway is not produced, giving the other phenotype.

What is the purpose of the motor neuron?

Papessa [141]

To send information from the brain or spinal cord to muscles and glands - is the purpose of motor neuron

Explanation:

As part of the central nervous system (CNS), the motor neurons connect the brain and spinal cord to all the muscles and glands present all over the body and innervates them.

Their main function is to transmit nerve impulses from the CNS to the muscles, both skeletal and smooth, and directly controls the movements of the muscles of the body.

A motor neuron is a typical nerve cell with multipolar body. It can be upper of lower motor neuron.

Right from snapping of fingers to movements of hamstrings, all muscular movements functions due to impulse carried by the motor neurons.

Degeneration of the motor neurons leads to neurodegenerative diseases like spinal muscular atrophy or amyotrophic lateral sclerosis.

Describe two pathways the student can use to show how a metamorphic rock

Lelechka [254]

Answer:

In order for a metamorphic rock to become a sedimentary rock, the rock must undergo erosion. Once the rock has eroded, it will produce rock fragments or sediments which accumulate to form a sedimentary rock. ... In turn, when igneous and sedimentary rocks are exposed to heat and pressure, the rocks become metamorphic.

Explanation:

hope this helps
