Based on the DNA sequence, the species that is most closely related to the unknown species is species 1, as it has more homologies than species 2. A bigger distance can be traduced in a higher number of mutations or modifications in the DNA sequence.

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.

As per Chargaff's rule the amount of DNA present in purine is equal to the amount in pyrimidines. G=C , guanine is 36%, A+T+G+C + 100% if C and G are 36 and 36 both, the remaining A and T are 100-72= 28 that is 14 and 14.

A DNA is made up of deoxyribonucleotides along with the ribose sugar and the phosphorous group. The collective is DNA.

According to CHAR GAFF it is the amount of DNA present in purine is equal to the amount of DNA present in pyrimidines where the both are having equal amount.

Answer:

A, Cell division

Explanation:

During cell division, in the phase called "anaphase" the spindle fibers pull apart the chromosomes to separate sides.

Since we now know it is from the phase anaphase, it could not be B or D.

We are now left with A and C.

Centrioles function is to organize the spindle fibers, this has nothing to do with pulling apart chromosomes.

Cell division has phases(PMAT), one of which is anaphase where this function occurs.

Water that started in the ocean could end up in a river inland as a result of the hydrological cycle via precipitation and also through land runoff.

This is also referred to as a biogeochemical cycle and it depicts the continuous movement of water in different areas on the surface of the Earth.

Precipitation such as rain, snow helps to ensure that water is recycled in the ecosystem so as  to prevent shortage or scarcity of such important resource in the ecosystem.

When there are high tides in the ocean , the water rises and moves several kilometers to other water bodies such as rivers thereby turning it from  river freshwater into brackish water which is therefore the way in which the water from the ocean gets to the river.

The "machines" that propel protein synthesis are called ribosomes, which receive the protein blueprint from a cell's DNA via messenger RNA (mRNA).

Messenger RNA provides the ribosome with the instructions needed to produce proteins. Amino acids are what proteins are made of. Transfer RNA is a different type of RNA that carries each amino acid in a protein to the ribosome.

During translation, ribosomal subunits create a sandwich-like structure on the strand of mRNA. From there, they are drawn to the amino acids connecting tRNA molecules (circles). A long chain of amino acids is created as the ribosome transforms the mRNA sequence into a polypeptide, or new protein.

fructose-6-phosphate; fructomannose isomerase

Mannose first undergoes phosphorylation by hexokinase before entering glycolysis. The phosphomannose isomerase enzyme then isomerises the freshly generated mannose-6-phosphate into fructose-6-phosphate. The sugar can now follow the typical glycolytic pathway because it is in the right shape.

Through fructose-1-phosphate, glucose enters the glycolytic route, mannose is phosphorylated to become mannose-6-phosphate, and galactose is enzymatically changed into glucose-6-phosphate.

Although both enzymes can phosphorylate other hexoses including fructose and mannose, they can also support development on glucose.

Answer: A. Cell divides into two daughter cells

Explanation:

During cytokine, the large cell must divide into two daughter cells to the last phase of meiosis.

the mutation rate of the achondroplasia gene in this population is 8.50 × 10⁻⁵

It is Given that Achondroplasia is an autosomal dominant disorder,

The total births = 94075,

Dwarfism achondroplasia affects ten infants.

The parents of two infants are also dwarfs. As a result, they passed on this condition to them.

Dwarfism caused by achondroplasia is an autosomal dominant condition. Therefore, those who inherit them from their parents must also have dwarf parents; those who do not have dwarf parents are the result of an achondroplasia gene mutation.

Infants having achondroplasia because of mutation = 10 - 2 = 8

8 infants have the achondroplasia gene mutation.

mutation rate = Infants with gene mutation / Total Infants
