The daughter cells come together to make another identical parent cell.
The brain requires blood flow to function properly, and cutting off blood flow to some of the brain's most important functions can be extremely harmful. Paralysis, sensory deficits, or even a stroke could result from a blockage of blood flow in the anterior cerebral arteries.
<h3>What causes a stroke?</h3>
A blocked artery (ischemic stroke) or a blood vessel leak or burst are the two basic causes of stroke (hemorrhagic stroke). Transient ischemic attacks (TIAs), which are brief interruptions in blood supply to the brain that don't persist long, can occur in some persons.
<h3>What happens when you stroke?</h3>
Depending on where in the brain the stroke occurs and how many brain cells are lost, the effects of a stroke might vary. Paralysis, trouble swallowing or communicating, memory loss, discomfort, emotional changes, and behavioral problems can all be brought on by a stroke.
<h3>What are the 4 signs of stroke?</h3>
- Face, arm, or leg weakness that appears out of nowhere (especially on one side of the body).
- abrupt difficulty speaking or understanding speech.
- sudden problem with eyes' eyesight.
- sudden dizziness or difficulties walking,

Answer:
In the transcription of DNA to mRNA, for the DNA sequence 3'-AGGTCTCAC-5' corresponds to an mRNA sequence 5'-UCCAGAAGUG-3'.
Explanation:
Transcription is the process by which a strand of mRNA, needed to direct protein synthesis in the cytoplasm, is synthesized from a strand of DNA.
The sequence of nucleotides in the RNA chain depends on the sequence of bases in the DNA strand, being placed according to the complementarity of nitrogenous bases, where a purine is complemented with a pyrimidine.
In RNA, the thymine base is replaced by Uracil, the complementary base to adenine of DNA.

For this reason:

Enter stationary phase of the bacterial growth curve. The rate of death of the bacteria is equaled by
the rate of replication. This is due to the stiff competition of the individuals
for the scarce nutrients. The bacteria begin to produce inhibitory molecules that also
increase the rate of mutations among the bacteria due to the harsh environment.
Answer:
A heterotroph is an organism that doesn't make their own food.
