Which explains why the reflex reaction is important in certain situations?
O A. Motor neurons cannot form action potentials.
O B. The brain has no control over motor neurons.
O C. Interneurons are too slow at sending signals through the spinal
cord.
O D. Sensory neurons do not use neurotransmitters to send signals.
Answer:
Answer:c
Explanation:
The reflex reaction is important in certain situations because interneurons are very slow to send signals through the spinal cord.
What is the reflex?The reflex is an automatic (read immediate and constant) bodily reaction to stimulation. According to Pieron, the reflex corresponds to any activity or variation of activity of an effector (muscle, gland, etc.)
With this information, we can conclude that the reflex reaction is important in certain situations because interneurons are very slow to send signals through the spinal cord.

Two students fertilize a pair of pea plants. One plant is Rr, and the other is rr. The offspring produced by
these two plants all had the dominant trait. The Punnett square showed that there was a 50 percent
chance of the offspring carrying rr genes. So, the student assumes that he made an error in determining
W the genetic makeup of the plants. Do you think the student made an error, or is there another
explanation?
No, even though it was only a 50% chance of being Rr, it still could have been that both plants got Rr, cause as long as it's greater than a 0% chance it can happen.

What would be the mRNA base sequence formed from ACC CTG GTA GCT
Answer:
Explanation:
DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using 'T' as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3' T C G T T C A G T 5', the mRNA sequence would be 5' A G C A A G U C A 3'.

Which factor can cause secondary succession?
clear cutting
Oglacial melting
Answer:
Hey!
Your answer is CLEAR CUTTING...
Explanation:
Clear cutting is when people/ industries harvest and regenerate trees areas in which all trees are cleared from a site completely...
HOPE THIS HELPS!!
Clear cutting can cause secondary succession. So, the correct option is A.
What is Secondary succession?When a place is disturbed but not severely enough to completely clear it of all vegetation and soil, secondary succession happens. Secondary succession can be started by a variety of disturbances, including fire, flooding, high winds, and human activities (such as logging of forests).
After the primary succession has indeed been disrupted as well as some animals and plants are still there, the secondary succession occurs. For the reasons listed below, the secondary succession is typically quicker than the primary succession.
There is already earth in place.The soil may still contain seeds, roots, and subsurface vegetative organs.Therefore, the correct option is A.

Which question would be asked in a dichotomous key?
A. How long are the insect's antennae?
B. Are the insect's antennae longer than its head?
C. Are the insect's antennae long or short?
D. How does the insect use its antennae?
Answer:
B. Are the insect’s antennae longer than its head?
Explanation:
Dichotomous key refers to the tool or method which helps the scientist to identify organisms.
It uses a specific series of questions which help in segregation of organisms and ultimately help the scientist to identify the organism on the basis of the observations or properties share by the organism.
Example of a simple dichotomous key is shown below.
Similarly, insects can have antennae longer or shorter than their heads. Thus, the question "Are the insect’s antennae longer than its head?" would help in segregating insects based on their antennae length.
happy to help ya:)
The statement B is correct. Are the insect’s antennae longer than its head?
What do you mean by dichotomous keys?A dichotomous key is an important scientific tool, used to identify different organisms, based the organism's observable traits. Dichotomous keys consist of a series of statements with two choices in each step that will lead users to the correct identification.
Moreover, for example, in tree identification, a dichotomous key might ask whether the tree has leaves or needles. The key then directs the user down one list of questions if the tree has leaves, and a different question list if it has needles.
Therefore, dichotomous keys are useful for biological classification as well as identification. The word dichotomous is derived from the Greek words meaning “two parts.” Each step in the key provides two contrasting choices about a characteristic.

Considering only the values of 0 for which the expression is defined, which of the following is equivalent to the expression
below?
sin0 x tan0 x sec0 x cot(-0)
Select the correct answer below:
O-tan
O cot0csc0sec0
O-cot0csc0sec0
O tan0
Answer:
A. [tex]-tan\theta[/tex]
Explanation:
Given
[tex]sin\theta\ .\ tan\theta\ .\ sec\theta .\ cot(-\theta)[/tex]
Required
Simplify
[tex]sin\theta\ .\ tan\theta\ .\ sec\theta .\ cot(-\theta)[/tex]
Substitute [tex]\frac{1}{cos\theta|}[/tex] for [tex]sec\theta[/tex]
So, the expression becomes
[tex]sin\theta\ .\ tan\theta\ .\ \frac{1}{cos\theta} .\ cot(-\theta)[/tex]
Rearrange the above expression
[tex]sin\theta\ .\ \frac{1}{cos\theta}\. \ tan\theta\ .\ cot(-\theta)[/tex]
[tex]\frac{sin\theta}{cos\theta}\. \ tan\theta\ .\ cot(-\theta)[/tex]
From trigonometry;
[tex]tan\theta = \frac{sin\theta}{cos\theta}[/tex]
So, we have
[tex]tan\theta\ . \ tan\theta\ .\ cot(-\theta)[/tex]
From trigonometry;
[tex]cot(-\theta) = -cot(\theta)[/tex]
So, the above expression becomes
[tex]tan\theta\ . \ tan\theta\ .\ -cot(\theta)[/tex]
[tex]-tan\theta\ . \ tan\theta\ .\ cot(\theta)[/tex]
From trigonometry;
[tex]cot\theta = \frac{1}{tan\theta}[/tex]
So, we have
[tex]-tan\theta\ . \ tan\theta\ .\ \frac{1}{tan\theta}[/tex]
Express as a single fraction
[tex]\frac{-tan\theta\ . \ tan\theta }{tan\theta}[/tex]
[tex]-tan\theta[/tex]
Hence, [tex]sin\theta\ .\ tan\theta\ .\ sec\theta .\ cot(-\theta) = -tan\theta[/tex]

after reading about epigenetics in your book, which do you think is the most important in shaping the person, genes or the environment?
State three things you do each day that affect the environment around you. Explain how the things you do affect the environment around you.
Answer:
Driving or using cars as a method of transportation increases the amount of Co2 released into the atmosphere. Due to this the environment becomes less and less unstable. Another daily thing I do every day that effects the environment is throwing away trash. As our trash fills the landfills some of them can be picked up by birds or even end up getting blown into the ocean. However, recycling is one positive aspect in our every day lives. When we recycle companies and factories are able to reuse things we no longer use. Because of this we are able to protect many ecosystems and the environment.

Which is NOT a role played by a type of RNA in protein synthesis?
O mRNA transcribes the DNA template.
rRNA makes up ribosomes, which translate the genetic code into a protein.
O tRNA pairs RNA bases with amino acids.
O pRNA is the product of chemically linked amino acids.
Answer:
pRNA is the product of chemically linked amino acids.
Explanation:
All the other choices are exactly the roles of RNA in protein synthesis: mRNA "messenger" RNA transcribes the DNA and travels out of the nucleus; then rRNA "ribosomal" RNA in the ribosome helps assemble the protein using the mRNA; tRNA "transfer" RNA brings amino acids to the assembly line of ribosome and mRNA.
There is no pRNA that I know of, although there are many types of other RNAs like piRNAs (piwi RNAs!) or siRNAs.
