Double Helix
Explanation:
Triple-stranded DNA is a DNA structure in which three oligonucleotides wind around each other and form a triple helix. In triple-stranded DNA, the third strand binds to a B-form DNA (via Watson–Crick base-pairing) double helix

Explanation:
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.
heart muscle cells have alot of mitochondria. why do you think this is?
Answer:
The heart is a vital organ with a high metabolic demand. Our heart muscles contain so much mitochondria because those muscles are very active in our body and require lots of energy to constantly pump blood through our circulatory system.

given the Dna Strand: ATG-CAG-AGA how would i transcribe the corresponding RNA Strand ?
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.Which chemical could be used to show that the cells are respiring aerobically

the rate of photosynthesis can be affected by several factors, such as light intensity, temperature ,water, and carbon dioxide. describe how the lack of water in an environment can affect the amount of carbon dioxide absorbed by the plant
Answer:
Plants need water, so that their guard cells can fill up and become turgid which would allow the stomata to open and gas to exchange. If there is not much water, not much gas exchange can occur hence not much Carbon dioxide can be taken in.
Explanation:
Plants require water for the process of photosynthesis. Plants need water so that their guard cells can fill up and become turgid. This allows the exchange of gases in the stomata.
How does water affect photosynthesis?
During photosynthesis, the plants take in carbon dioxide and water molecules from the air and soil particles. Within the plant cell, this water is oxidized to generate oxygen gas, meaning that it loses electrons, while the carbon dioxide gas is reduced in the chloroplast of the plant cell by gain of electrons to produce carbohydrates. This process transforms the water into oxygen gas and the carbon dioxide gas into glucose molecules (carbohydrates).
Plants need water, so that the guard cells in the plant can fill up and become turgid which would allow the stomata to open and exchange of gases. If there is not much water present in the guard cells, not much gas exchange can occur hence not much of the carbon dioxide can be taken in from the atmosphere.

Why is the dysphotic zone around coral reefs shallower than the dysphotic zone in the open ocean?
There is more oxygen in the open ocean.
The sun is brighter over the open ocean.
There is more nitrogen by the coral reefs.
There is more plankton by coral reefs.
Answer: There is more plankton by coral reefs.
Explanation: Plankton tend to hang around surface waters which coral reefs also grow in. And most of that Plankton are plants that need more sunlight. So the sun would be brighter in shallower waters rather than open ocean.

a cell was poisoned by a substance that destroyed all of its mitochondria. which cell transport processes would be able to still continue?
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.
