<span>The correct answer is 'metastasis'. This is the migration of cancer cells from one place to another in the body. They do this by travelling through the blood stream or the lymphatic system.
Mitosis is the process of asexual cell division. It produces cells that are identical to the original cell as one cell divides into two after replicating its organelles and genetic information. (Mitosis makes my toes.)
Apoptosis is controlled cell death. When cells are getting old then they need to be replaced. Old cells are programmed to 'die' at the correct time. The cell contents are recycled to make new cells.</span>
Answer;
-Nuerotransmitters
Neurotransmitters that are not reabsorbed drift out of the synaptic gap, through diffusion. This is how the synaptic gap is cleared, in preparation for the next release of a new batch of these chemical messengers.
Explanation;
-The majority of neurotransmitters drift across the synaptic gap and come into contact with receptor sites of the receiving neurons dendrites. Receptor site is the location where neurotransmitters attach on the receiving side of the synaptic gap. Because there are a variety of neurotransmitters a variety of receptor sites also exist.
-It is necessary for the right neurotransmitter to fit a corresponding receptor site to convey the message.
-When the neuro transmitters latch onto the receptors of the dendrites of the receiving neuron tiny gates in the receiving cells membrane fly open ushering positively charged particles into the cell and restarting the cycle of action potential.
-The firing of one neuron contributes to the potential for neighboring neurons to fire as a result of its chemical message. Reuptake process by which neurotransmitters are reabsorbed by the sending terminal bud. Neurotransmitters that are not reabsorb drift out of the synaptic gap through diffusion
Answer:
Hydrogen bonds tend to be weaker than covalent or ionic bonds. The hydrogen bond formed between water molecules has a dissociation energy of 0.24 eV. A hydrogen bond has is approximately 90% ionic and 10% covalent. Van der Waals bonds are weak bonds with a dissociation energy of about 0.01 eV.
Explanation:
Answer:
A. 50% Type A, 50% Type B
Explanation:
To answer this we can draw a punnett square.
Since o if recessive, it can only be expressed if it is not masked by a dominant allele. Therefore the male with type O blood has the genotype oo. A and B are co-dominant, so the woman has genotype AB.
_ | A | B
o |Ao | Bo
o | Ao | Bo
Since A and B are dominant alleles, they will mask the o allele. Therefore genotype Ao will be a Type A phenotype, and genotype Bo will be a Type B phenotype.
Therefore, the phenotypic probabilities for this cross is 50% Type A, 50% Type B. Hence, the answer is A.
Hope this helped!
I believe that identical copies of original DNA wouldn't be formed.
DNA has a strict pairing rule, adenine can only go with thymine, and cytosine can only go with guanine.
This is because of thymine and adenine make 2 hydrogen bonds between each other, while cytosine and guanine form 3. Therefore bonding out of this order is impossible (unless it's a mutation in which there are exceptions).
<span>When DNA replicates, each strand of the original DNA serves as a template for the new strand of DNA. Hence the new strand that goes with the first original DNA strand is the same as the second DNA strand.
</span>If the bonding between the nitrogen bases is messed up, the new strand of DNA will not be exactly what it should be. To demonstrate, if the nucleotide is thymine for the original strand, the new strand should be adenine. <span>However, if the bonding is arbitrary, then the new strand could be cytosine or guanine as well, therefore there is no definite answer to what the new strand should be. This will make havoc in the genetic codes and will most likely kill the organism.
</span>I hope this answer has answered your question and good luck with your assignment. I apologise if I am incorrect. Have a good day/night.
