Within a population of butterflies, the color brown (B) is dominant over the color white (b) and 32% of all butterflies are whit

e. Given this simple information, which is something that is very likely to be on an exam (teehee), calculate the following:
1. The percentage of butterflies in the population that are homozygous dominant
2. The number of heterozygous butterflies if the population contained 4,216 individuals

Answer:

48% Heterozygous of the population, 12% Homozygous dominant size.

Explanation:  

Given the characteristics of its population,

Brown (B) predominates over white (b) color.

Recessive phenotype frequency (Q)= 40%= 0.4

According to the Hardy-Weinberg principle, the frequency is given by P and Q for a population with the dominant and recessive trait, where P+Q=1 preserves the equilibrium of the population allele.

So then, P = 1-Q

P=1-0.4=0.6

Heterozygotic butterflies = 2PQ

So, 2PQ= 2x0.6x0.4=0.48

That is, 48 percent of people are heterozygous

Homozygous dominant individual frequency = 1-(40 + 48) = 12 i.e. 12%

The density of protists living in the hay infusion is ______________ than the regular pond water.
iren2701 [21]

Answer:

a. significantly lesser

Explanation:

The density of protists living in the hay infusion is significantly lesser than the regular pond water because protists likes to live in aquatic or any water bodies. Some protists float on the surface of the water making their own food like plants by using the process of photosynthesis. Aquatic environments are ideal environment for protists, which have cilia and flagella that allows them to move in the water in search of food..

Give two reasonsthat may account for the continuous firing of a<br> PostsynapticNeuron.
lyudmila [28]

Answer:

1.Continuous diffusion of negatively charged ions into the postsynaptic neurons , <u>which  leads to continuous reversal of charges (hyperpolarization) and therefore continuous firing of action potential</u>

2. Inhibition of hydrolytic enzymes e.g (acetycholinesterase)   that  metabolize activities of  cholinergic   neurotransmitters  e,g acetycholine at post synaptic cleft. leading to firing of action potential.

Explanation:

Neuron whose dendrites  transmits action potential to the  neuromuscular junction is called presynaptic neuron. While  neuron that  transmit action potential away from the neuronal synaptic junction, or from the neuromuscular  junction to the cell body of adjacent neuron or to effectors (gland and muscles) are called  post synaptic  neuron.

The more  negatively charged ions that diffused into the post synsptic neuron, the more depolarization, and the greater the frequency of action potential produced

The inhibition of  activities of hydrolytic enzyme which metabolize cholinergic neurotransmitter leads to  continuous   excitatory activities  of cholinergic neurotransmitters   on  the receptors at the postsynaptic neuron, and the more  action potential
