Biology
1 answer:
forsale [732]3 years ago
4 0

Answer:

The presence of freckles in a individual, or predisposition to have them, is a trait that is inherited with an autosomal dominant pattern, and is not related to sex-linked inheritance.

Explanation:

Freckles are accumulations of melanin in the skin, which form small reddish or light brown spots, predominantly in white-skinned people.

<u> The melanocortin receptor gene</u> undergoes a change that gives rise to a variant - which is phenotypically expressed in the presence of freckles - whose inheritance has been determined to be autosomal dominant.

<u>Under no circumstances is the transmission of the gene that determines the presence of freckles linked to sex</u>, because is an autosomal trait, as is hair, eye or skin color.

garri49 [273]

Answer:

myofibril bulbous end of axon and skeletal muscles fibres.

Explanation:o

It represents the  chemical synapse  of the axon bulbous ends  of the motor neuron ( motor end plate) and the skeletal Muscle fibres.

The influx of calcium ions into the bulbous ends leads to the fusion  and empty of the vesicles containing neurotransmitters into the synaptic cleft.

The Neurotransmitters binds to the receptors on the muscles membrane to allow the transmission of action potential ( PSIP or  PSEP)across the synaptic gap  to the muscles fibers  to initiate  their  contraction or relaxation.

Explain how to estimate a population using random sampling
Nina [5.8K]
Subjects in the population are sampled by a random process, using either a random number generator or a random number table, so that each person remaining in the population has the same probability of being selected for the sample.

How to Estimate a Population Total from a Simple Random Sample

1. This lesson describes how to estimate a population total, given survey data from a simple random sample. ...

2. Sample mean = x = Σx / n.

3. Population total = t = Nx.

4. where N is the number of observations in the population, and x is the sample mean.

A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen. ... In this case, the population is all 250 employees, and the sample is random because each employee has an equal chance of being chosen.

Random sampling is a part of the sampling technique in which each sample has an equal probability of being chosen. A sample chosen randomly is meant to be an unbiased representation of the total population.
