If the nervous system of the neurotransmitters in your body were suddenly blocked from passing into the synaptic spaces then your neurons would not be able to communicate and you would die.
If your body lacked sufficient neurotransmitters, your neurons would be unable to communicate with one another, and you would pass away. Neurotransmitters are important because neurons need them to communicate.
If a medicine suppressed the neurotransmitter receptors, the damaged neurons would be unable to communicate with other neurons or tissues. This occasionally has positive benefits for the organism, but it can also be harmful or even fatal.
These neurotransmitters diffuse across the synaptic gap, attach to receptors on postsynaptic cells, change the membrane potential of those cells, and potentially even trigger the postsynaptic neuron to repeat the cycle.

What is the purpose of transcription?
The purpose of transcription is to create an mRNA copy of a gene, allowing the genetic material to leave the nucleus and go to the site where it can be assembled into a protein.
By severing the hydrogen bonds between the base pairs, an area of the DNA double helix is uncoiled by the enzyme DNA helicase.As exposed base pairs on the template DNA strands, complementary nucleotides from the nucleoplasm align up to them.Along the strand, the RNA polymerase enzyme forms phosphodiester linkages between neighbouring nucleotides.This procedure continues until the pre-mRNA is entirely produced and RNA polymerase reaches a stop codon.The mRNA strand then exits the nucleus after non-coding introns have been spliced out by the spliceosome's enzymes.A missense mutation _____ the dna sequence and _____ the resulting amino acid sequence.
Answer:
changes, modifies
Example:
we'll use ATG
go through transcription
we have UAC now
now we have a missense mutation
we'll do GAC
see how we changed the U to a G?
This change also changed the amino acid
before, for UAC we had Tyrosine
Now, for GAC we have Asp acid
IF we had no change in the amino acid, it would be a silent mutation, but since we did it is a missense mutation.
hope that helped :)

What would be more likely to carry out exocytoi: a white blood cell engulfing foreign material or a cell that excrete hormone? Ue evidence/reaoning to upport your anwer
Hormone excretion involves the movement of molecules outside the cytoplasm. This is known as exocytosis.
What is exocytosis ?Exocytosis is a type of active transport and bulk transport in which molecules are transported out of the cell. Exocytosis, as an active transport mechanism, necessitates the use of energy to transport material.Exocytosis is a type of bulk transport because it involves the release of a large number of molecules. Exocytosis occurs via secretory portals called porosomes at the cell plasma membrane. Porosomes are permanent cup-shaped lipoprotein structures at the plasma membrane of cells, where secretory vesicles dock and fuse to release intracellular contents.Exocytosis involves the transport of membrane-bound secretory vesicles to the cell membrane, where they dock and fuse at porosomes, and their contents are secreted into the extracellular environment. Because the vesicle transiently fuses with the plasma membrane, this secretion is possible.To learn more about exocytosis refer :

What is guinea pigs?Genotypes are the allelic components of an organism's genetic makeup. Phenotypes are the outward manifestations of an organism's physical characteristics. Two RR genotypes and two Rr genotypes are observed as a result.
As a result, the genotypes are 1:1 RR and Rr. All of the offspring have rough coat phenotypes since R stands for rough coats.
A few of the enticing characteristics of guinea pigs include their small size, mild temperament, and friendliness. They need particular care and consideration, though, just like all companion animals.

As you walk along the X-axis to the right, the temperature drops. As you advance up the Y-axis, Absolute Magnitude grows. As a result, choices B and C are the right ones.
Hertzsprung-Russell Diagram, or H-R, is a graph of the temperature and brightness of stars. Given that color and temperature are related, it displays color. The data for thousands of stars were plotted by these two astronomers, and they identified certain patterns.
One of the most crucial tools for studying star evolution is the HR diagram, often known as the Hertzsprung-Russell diagram (HR diagram). It was separately created by Ejnar Hertzsprung and Henry Norris Russell in the early 1900s and shows either the color of stars (or spectral type) against their absolute magnitude or the temperature of stars against their brightness (the theoretical HR diagram) (the observational HR diagram, also known as an Absolute Magnitude diagram).
As a result, we may state that the Absolute Magnitude increases as you walk up the Y-axis and the Temperature decreases as you move to the right on the X-axis.

Match the letters with the main components involved in protein synthesis
The correct match of the letter with the main components of protein synthesis in the given diagram are: (A)- Translation; (B)- m-RNA; (C)- t-RNA; (D)- Ribosome; (E)- Anticodon and (F)- Codons.
Translation is the name of the process of formation of protein from the m-RNA strand. The process occurs in the cytoplasm of the cell where ribosomes are present. The m-RNA sequence is read by the anticodons on t-RNA and the correct amino acid is inserted into the polypeptide chain accordingly.
Ribosome is a nucleoprotein. It is the most important machinery for the synthesis of proteins. There are 2 subunits of protein a small and a large one. These subunits join together at the time of translation. There are two types of ribosomes: a 70S type ribosome and a 80S type ribosome.

What is molecular genetic manipulation
Please explain
Answer:
Molecular genetics is the manipulation of an organism's genome. There have been many uses of MG outside the farm gate for generating customised bacterial cultures. When MG is used in dairy animals, it results in transgenic animals with new traits that can't be achieved through standard breeding techniques. Inside the farm gate, MG plays a role in animal breeding. Causative mutations or linked genetic markers that cause phenotypic differences are being identified using MG. This approach aims to disseminate superior genetics to commercial farmers effectively and efficiently.

Plasma blood group B has B antigens and anti-A antibodies. O - has no antigens, but the plasma blood group has both anti-A and anti-B antibodies. Blood group AB lacks antibodies but possesses both A and B antigens.
There are a total of 8 blood types, each of which can be either RhD positive or RhD negative. Sometimes a protein known as the RhD antigen, another antigen, is present in red blood cells.

After being used by the major organs of the body, deoxygenated blood is transportedback to the right side of the heart by two large veins known as theand enters the, quickly passing by the openvalve, where blood then enters and fills thechamber.After filling, the cardiomyocytes contract, produce force on the blood and push openthevalve and allow blood to exit into theBlood now enters the circulation of the lung for gas exchange to occur. Onceoxygenated, blood returns to the heart from the lungs by way of four large vesselscalled the, blood then moves into theandpast the openvalve filling thechamber.From here, oxygenated blood is pushed past thevalve and intothewhere blood is pumped into the systemic circuit.
Deoxygenated blood is transported back to the heart by the superior and inferior vena cava, it enters the right atrium, and it passes the opened tricuspid atrioventricular valve to the right ventricle.
The cardiomyocytes of the right ventricle contract and push the blood through the pulmonary semilunar valves to the pulmonary arteries. The blood flows through the pulmonary system, where the gases are exchanged, and the blood is oxygenated.
Then the blood returns to the heart through the pulmonary veins to the left atrium and past the bicuspid atrioventricular valve to the left ventricle.
When the left ventricle contracts, the blood is pushed through the aortic semilunar valves into the aorta where it enters the systemic circulation.
