<u>Answer:</u>

The correct answer option is D. Carry nerve impulses from the brain to skin, glands, and muscles

<u>Explanation:</u>

Motor neurons carry signals out of the Central Nervous System (CNS).

These motor neurons have long extensions called axons which spread from the CNS to the muscles that connect with the innervate.

The information from the brain to the muscles and other glands is sent in the form of electrical impulses via the spinal cord.

Trava [24]
I believe he is looking for an allele
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosomes. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.

What are the differences between prokaryotic and eukaryotic cells? Focus on cells from microscopy lab?
pishuonlain [190]

Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.

There are several key differences between prokaryotic and eukaryotic cells. Eukaryotic cells are found in multicellular plants and animals, whereas prokaryotic cells are found in bacteria and archaea which are ususlly unicellular. I have summarised the key differences below:

Prokayotic cells do not have membrane-bound organelles, such as the endoplasmic reticulum or mitochondria.

Prokaryotic cells do not have a nucleus, instead they have circular DNA that is free in the cytoplasm.

Prokaryotic cells have smaller ribosomes than eukaryotic cells.

Prokaryotic cells have a cell wall. Their cell wall is made from a different material to a plant cell, a glycoprotein called murein.

Prokaryotic cells may also have a protective layer called a capsule, flagellum to aid in movement and one or more plasmids.

In a species of bird, the allele for the striped trait is recessive to the allele for the speckled trait. Suppose that a coastal
mylen [45]

Answer:

The answer is "0.42"

Explanation:

Please find the complete question in the attached file.

Coastal community striped allele intensity = q = 0.62

Landlocked community, strip intensity allele=q'=0.40

Its eliminated allele frequency for movement = q"=0.42 \ in \ indoorscommunity And now in the sturdy vineyard optimum communities, genotype frequency of stripped characteristic (heterozygous device) in coasts=q_2=0.39

Heritable (striped) allele frecency:

\to q=\sqrt{q_2}

      =\sqrt{0.39} \\\\ =0.624 \\\\ =0.62

(round up to the closest cent) is therefore the only frequency of coastal people.

The genome of pulling function in host population= q'_2=0.16 Heterozygous feature regularly.

Therefore the inland community rate of recessed (striped), allele rate:

\to q'= \sqrt{q'_{2}}= \sqrt{0.16}=0.40

Following migration;

Its percentage of coastal migrants:

m=10\% \\\\

   = \frac{10}{100} \\\\= 0.1

Coastal population Non-immigrant percentage of coastal residents:

=1- m\\\\=1-0.1\\\\ =0.9

Stripping coastal community of allele rate after immigration:

(q")=\text{(stripping of migrant only freq)}\times (m)+\text{(stripping allele baud rate for non-immigrants)} \times ( 1-m)

       = [q \times m]+[[q' \times(1-m)]\\\\=(0.62 \times 0.1)+(0.40 \times 0.9)\\\\=0.062+ 0.36\\\\=0.422\\\\=0.42

Meteorologists draw lines called ______ on weather maps to connect locations with the same air pressure.
natta225 [31]

The correct answer is isobar.  

The isobars refer to the lines of constant pressure. It is a line drawn on a map of a weather linking the points of equivalent pressure. The isobars are produced from mean sea level pressure reports and the values of pressure are illustrated in millibars.  

The isobars help in demonstrating that how pressure are changing over space and so assist in illustrating the large-scale weather patterns across a region on the map.

Butoxors [25]

Answer:

The enzyme function best at a specific temperature.

Explanation:

Enzyme activity is affected by temperature. Each enzyme has a specific temperature range in which it works most effectively. Most biological enzymes present in the human  body have an ideal temperature range of around 98.6 degrees.
