In the menstrual cycle, the Ovary releases an egg every 14 days.
Your uterus' lining sheds each month throughout your menstrual cycle period. The words menses, menstrual period, cycle, and period are also used to refer to menstruation. Flowing from your uterus through your cervix and out of your body through it, menstruation blood is a mixture of blood and tissue from the interior of your uterus. When your body prepares for the possibility of pregnancy each month, a series of processes known as the menstrual cycle take place. It is believed that a menstrual cycle starts on the first day of a period. The duration of a cycle can vary from 21 to around 35 days, with the typical cycle lasting 28 days.

List and briefly explain four reasons why plants are propagated vegetatively(rather than sexually propagated)
As we know that plants reproduces through the process of vegetative propagation as vegetative propagation can be defined as the type of asexual reproduction, which takes place in plants to form new plants from a parent plant part.
What is vegetative propagation?The term vegetative propagation has been defined as the type of asexual reproduction, which takes place in the plants to form new plants from a parent plant part. Plants produced by the process of vegetative propagation are identified as clones of their parent plants as there has no involvement of genetic material during the process.
The formation of the new plants through the parts such as bulbs, grafting, tuber, cutting or tissue culture are examples of the process of vegetative propagation.

What terminology is used to describe a mutation that has no effect on the protein produced from the mutated gene?.
Silent mutation is used to describe a mutation that has no effect on the protein produced from the mutated gene.
Silent mutations are DNA mutations that have no discernible effect on the organism's phenotype. They are a subset of neutral mutations. The terms silent mutation and synonymous mutation are frequently used interchangeably; however, synonymous mutations are not always silent, and vice versa.
A silent mutation is a type of substitution mutation, or point mutation, in which the change in the gene's DNA sequence has no effect on the amino acid sequence.
Silent mutations cause a change in one of the letters in the triplet code that represents a codon, but the amino acid that is coded for remains unchanged or similar in biochemical properties despite the single base change.

Mannose enters glycolysis in what way?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.
Mannose, galactose, and fructose enter the glycolytic process in what way?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.

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.

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.

what would happen to your nervous system of the neurotransmitters in your body were suddenly blocked from passing into the synaptic spaces
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.

The process of glycolysis is the breakdown of fatty acids molecule in the body.
Glucose is metabolized to pyruvate by glycolysis in the cytoplasm, and pyruvate is fully oxidized to ATP by the TCA cycle and oxidative phosphorylation in mitochondria. Upon feeding, fatty acids are synthesized by de novo lipogenesis using products of glycolysis.
Glycolysis is the process by which glucose is broken down for energy. Produces his two molecules of pyruvate, ATP, NADH, and water. This process takes place in the cell's cytoplasm and does not require oxygen. Found in both aerobes and anaerobes.
This is the first step in cellular respiration. In glycolysis, sugar molecules are broken down to release the energy needed for cell metabolism. It is found in the cytoplasm of cells.
