define the term gene mutation
Answer:
gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes

In order to ascertain the prevalence and pattern of antibiotic susceptibility of uropathogens among patients at Bharatpur Hospital, this study was carried out.
An increased prevalence of antibiotic resistance among UTI patients signals the need for ongoing surveillance to ensure effective infection control. It can be advised that women, in particular, be aware of proper hygiene practises and use antibiotics sparingly when necessary.

How many times do cells undergo Mitosis in order to become a gamete?
Answer:
two
Explanation:
When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides by way of meiosis, it produces four cells, called gametes.
Answer:
Cells do not undergo mitosis to become gametes although Somatic Cells go through Mieosis 1 & 2 to become gametes.
Explanation:
Specifically a somatic cell is split twice where on parent cell ends up into 4 daughter cells through Meiosis 1 and 2
Mitosis produces the exact same cell so if you did mitosis on a somatic cell it would never happen. But if you did it on a cell already a gamete it would only take one division

The genes for the traits that mendel worked with are either all located on different chromosomes or behave as if they were. How did this help mendel recognize the principle of independent assortment?.
Mendel recognized the principle of independent assortment by working with the genes located on different chromosomes as otherwise, his dihybrid crosses would not have produced a 9:3:3:1 ratio for F2 phenotypes.
Mendel's law of independent assortment states that during a dihybrid cross, the assortment of each pair of traits is independent of the other. This means that, during gamete formation, one pair of traits is separated from another pair of traits independently. The genes for the traits that Mendel worked upon were located on different chromosomes or behaved as if they were. This feature helped Mendel to conclude with his finding as a law of independent assortment.
Gregor Mendel performed dihybrid crosses between organisms having two different traits: seed color and seed shape. One parent was homozygous dominant (YYRR: Yellow round) and the other was homozygous recessive (year: green wrinkled) for two different traits. He produced a heterozygous dominant trait ( YyRr: Round yellow) in the F1 progeny. When F1 progeny was self-crossed, he observed that the phenotypic ratio was 9:3:3:1. This means that the F2 progeny resulted in four different combinations of seeds: wrinkled yellow, round yellow, wrinkled green, and wrinkled yellow seeds.
With the genes located on different chromosomes, it was made easier for Mendel to observe the phenotypes in F2 progeny.

3. Why is it necessary for the cell to grow and duplicate its DNA before the start of meiosis?
Answer:
Since the cell is dividing it needs two copies of it's DNA. One is kept by the parent cell and the other is passed to the daughter cell..... So this process of duplicating DNA is very important, because the daugher DNA cell will likley die.
Explanation:
gated ion channels gated ion channels are found only on vesicles. open and close in response to a stimulus. move molecules against an electrochemical gradient. require atp hydrolysis.
Gated ion channels are open and close in response to a stimulus.
What is a stimulus?A stimulus in physiology is a perceptible alteration in the physical or chemical composition of an organism's internal or external environment. Sensitivity refers to an organism's or organ's capacity to recognize external stimuli and respond appropriately (excitability). As with touch receptors in the skin or light receptors in the eyes, sensory receptors can pick up information from both within and outside the body. Chemoreceptors and mechanoreceptors are examples of internal sensory receptors. A stimulus can trigger a response via stimulus transduction when it is recognized by a sensory receptor.
