Plants participate in both short- and long-distance signaling. Explain how nerve cells show these two functions, as well. (3 points)
Nerve cells release chemical signals into synapses between them (short distance). They also transverse their lengths with an electrical signal that can result in signal travel along a series of cells (long distance).
Nerve cells release hormones into the synapses between them (short distance). These hormones can also transverse the bloodstream (long distance).
Nerve cells release neurotransmitters into gap junctions between them (short distance). They also use electrochemical gradients that can travel the length of each cell quickly, along a network of cells (long distance).
Nerve cells use plasmodesmata to communicate between them individually (short distance). They also use ion-gated channels to create an electrochemical signal that can be propagated over long distances in their network (long distance).

Answer:
Nerve cells release chemical signals into synapses between them (short distance). They also transverse their lengths with an electrical signal that can result in signal travel along a series of cells (long distance).
Explanation:
Nerve cells release neurotransmitters in the synaptic cleft which are capable of affecting nearby cells such as other nerve cells and muscle cells. Neurotransmitter molecules include, among others, serotonin, acetylcholine, dopamine, norepinephrine and histamine. Moreover, the synaptic cleft is the space that separates a neuron cell and its target cell. On the other hand, neurons transmit signals through electrical impulses. Electrical impulses travel long distances in the body carried by axons of the nerves. Thus, nerve impulses connect the brain and spinal cord and they carry signals to different parts of the body.
a cell was poisoned by a substance that destroyed all of its mitochondria. which cell transport processes would be able to still continue?
Answers
Answer:
Nothing
Explanation:
If a cell's mitochondria were destroyed it would die. Mitochondria are the power houses of the cell and without energy, necessary reactions could not take place .
If a mitochondria stopped working the cell would not have its respiratory function such as to use carbon dioxide, water, and energy in which the cell needs to survive so the cell would eventually stop moving and slowly die out with no nutrients and energy.

17. Which of the following best describes how amino acids affect the tertiary structure of a
protein?
a) The number of amino acids determines the tertiary structure of the protein.
b) The interactions of the different R-groups with other R-groups and with their environment
determine the tertiary structure of the protein.
c) The R-group of the last amino acid that is added to a growing polypeptide chain
determines the next amino acid that is added to the chain.
d) The sequence of the amino acids in the polypeptide chain determines the protein's
primary structure but has no effect on its tertiary structure.
Answers
Answer:
It is B
Explanation:
I had this question on my test last week
The tertiary structure of the protein is determined by the interactions of the different R-groups with other R-groups and with their environment in the protein (Option B).
An R-group (also called variable group) is a side chain that is attached to the α-carbon of the amino acids, the building blocks of proteins.The linear sequence of amino acids within a protein is the primary structure of proteins. The second structure of proteins is determined by the pattern of hydrogen bonding in the peptide backbone. The most common secondary structures of the proteins are alpha-helices and beta-sheets.The protein tertiary structure is the 3D (tridimensional) shape of the protein, which is due to interaction among R groups of amino acids and with their environment.The most common tertiary structures of the proteins are globular and fibrous structures.Finally, the quaternary structure of the proteins is determined by the interaction of several protein chains or subunits.In conclusion, the tertiary structure of the protein is determined by the interactions of the R-groups and with their environment in the protein (Option B is correct).

B. A few members of the population develop
mutations in somatic cells.
C. A large number of the population migrates
over a great distance
D. A few members of the population are isolated

Answers
Answer: D
Explanation:
Use Darwin’s finches as example they were separated and speciation occurred in the changed beaks
In which situation is speciation MOST likely to occur is few members of the population are isolated from the others.
What can cause speciation?The speciation process usually occurs due to adverse conditions imposed by the environment. Briefly, two causes are attributed for the process to occur: Geographical Isolation: When lineages of a species separate from the rest of the species for environmental reasons.
In this case, a species no longer identifies with it and thus it isolates itself from its environment.

Rotation Speed Revolution Speed Solar System Speed Milky Way Speed
0.3 miles/sec
18.5 miles/sec
370 miles/sec
150 miles/sec
The rotation speed and revolution speed should be switched
The revolution speed and solar system speed should be switched
The rotation speed and Milky Way speed should be switched.
The solar system speed and Milky Way speed should be switched.
Answers
Answer:
The solar system speed and Milky Way speed should be switched.
Explanation:
The speed of the Earth is with respect to how it moves around it's own axis (rotation speed), the Sun (revolution speed), solar system (solar system speed), and the milky way galaxies (milky way speed) etc.
According to this question, Luca made a chart for this Earth's four basic movements. The chart with their respective speed are as follows:
Rotation Speed - 0.3 miles/sec
Revolution Speed - 18.5 miles/sec
Solar System Speed - 370 miles/sec
Milky Way Speed - 150 miles/sec
Luca, however, made a mistake in his chart.
- The rotation speed of the Earth around its axis is correctly 0.3miles/sec
- The revolution speed of the Earth around the sun is correctly 18.5 miles/sec
- The solar system speed of the Earth i.e. around the solar system is about 150miles/hour
- The milky way speed of the Earth i.e. around local group of galaxies is about 370miles/hour.
Based on the comparison of Luca's chart and correct speed illustration, THE SOLAR SYSTEM SPEED AND MILKY WAY SPEED SHOULD BE SWITCHED.

given the Dna Strand: ATG-CAG-AGA how would i transcribe the corresponding RNA Strand ?
Answers
Answer:
The RNA strand that is transcribed from the DNA strand sequence ATG-CAG-AGA is UAC-GUC-UCU, according to the complementarity of nitrogenous bases.
Explanation:
In order for DNA to RNA transcription to occur, one must be aware that:
The transcription meets the criteria of base complementarity, where a purine binds to a pyrimidine. In RNA there is no thymine, so it is replaced by uracil.Given a given sequence of bases the RNA resulting from transcription will be governed by these rules:
DNA: ATG-CAG-AGA
RNA: UAC-GUC-UCU
Where:
Adenine is transcribed in Uracil. Thymine (DNA) is transcribed into Adenine. Cytosine is transcribed into Guanine. Guanine is transcribed into Cytosine.PLEASE HELP! :(
