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.
Explanation:
What organisms carry out metabolism?
Answer:
Eukaryotes
Explanation:
Are organisms wise cells have a nucleus and membrane bound organelles. Prokaryotes are organisms whose cells lack a nucleus. Eukaryotes carry out cellular respiration with the help of mitochondria. Mitochondria are organelles that produce the enzymes necessary to catalyze the series of reactions that produce ATP.

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.

What is difference between acid and bases?
Definition. A substance, mostly liquid that donates a proton or accepts an electron pair in reactions. An acid increases the concentration of H+ ions. A base is a substance that releases hydroxide (OH-) ions in aqueous solution, donates electrons and accepts protons.
(just if someone needs this i guess)
Answer:
Acids are sour, gives burning sensation, generally sticky, reacts with metals to produce hydrogen gas. Although bases are opposite as they are bitter, generally odorless (except ammonia), they are slippery; bases react with fats and oils. In phenolphthalein, indicator acids remain colorless, and base gives pink color.

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.Kevin is constructing an explanation of the importance of freshwater ecosystems. Which of these statements would be MOST USEFUL to include in the explanation?

A strand of DNA contains the bases adenine, cytosine, cytosine, and guanine, in that order. Which would be the order of the bases on the opposite strand of DNA?
cytosine, adenine, adenine, and thymine
cytosine, thymine, thymine, and adenine
thymine, guanine, guanine, and cytosine
thymine, adenine, adenine, and cytosine
Answer:
thymine, guanine, guanine, and cytosine
Explanation:
The order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.
DNA and complementary base pairingThe deoxyribonucleic acid (DNA) is a double helix composed of two long chains of sequential nucleotides.
In DNA there are four classes of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine, Thymine).According to the base pair rules of complementarity, Adenine always pairs with Thymine, whereas Guanine always pairs with Cytosine.In conclusion, the order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.

You are walking in a clear-cut section of forest a few days after a heavy rainstorm A nearby stream is very muddy and has
many dead fish. What might have happened?
Answer:
in my oppinion its call a
source of pergisol
Explanation:
What if climate change is self-sustaining? This is already the case, for example, with melting arctic sea ice. This reflects solar radiation, which allows the ocean, located under the ice, to stay cold. But when sea ice melts, the ocean absorbs heat from the sun, which melts more ice. In general, it is difficult to predict the tipping point where such a feedback loop will engage.
Spread over more than 23,000,000 km2, at the top of the globe, permafrost (permanently frozen ground) could enter such a vicious circle. Normally, up to 4 m of soil and plant debris cover the permafrost. This top layer (called the active layer) normally melts every summer, and freezes in winter. It thus protects the permafrost from the rise in heat outside. But in the spring of 2018, a team working at a research station in Tchersky, Russia, discovered that near-surface land had not frozen over at all during the long, dark polar night.
