1. What is the total magnification of the specimen under the 10x objective on our virtual microscope?
You can see the slide more clearly than with a scanning focal plane without going near for public viewing since a minimum power focal plane and a 10x eyepiece lens together have a total magnification of 100x.
What does magnification mean?A microscopic organism can be seen, for example, when a small thing is magnified to appear larger. Resolution is the capacity to tell two items apart from one another. Resolution and magnification are both limited in light microscopy.
What has a 10x magnification?In a standard desktop microscope, the eyepiece is 10x. The ultimate microscope magnification is calculated as the sum of the objective amplification and the eyepiece magnification.

which part of the eye changes how much light enters the eye?
Answer: The Iris
Explanation:
The iris is the colored ring of muscle tissue located in the front of the eye, surrounding the pupil. The pupil is the opening in the center of the iris that allows light to enter the eye.
The iris regulates the amount of light that enters the eye by controlling the size of the pupil. When the iris contracts, the size of the pupil decreases, allowing less light to enter the eye. This is known as "miosis" and is the body's response to bright light. On the other hand, when the iris relaxes, the size of the pupil increases, allowing more light to enter the eye. This is known as "mydriasis" and is the body's response to dim light.
In summary, the iris, which is the colored ring of muscle tissue in the front of the eye, controls the amount of light that enters the eye by adjusting the size of the pupil, the opening in the center of the iris.
If dometicated dog, hair type i controlled by two different allele. The allele for wire hair i (H) and the allele for mooth hair i (h). When two heterozygou dog are croed , what percentage of the offpring i expected to be homozygou for mooth hair?
The wire hair allele is (H), and the smooth hair allele is (h), and when two heterozygous canines are crossed, the level of the posterity is supposed to be thoroughbred for smooth hair, which is 25% present in choice B.
Heterozygous is a hereditary term used to portray an organic entity that has two distinct alleles for a specific quality. This implies that the organic entity has acquired two distinct adaptations of similar quality, one from each parent. In hereditary qualities, heterozygosity is a state wherein the two alleles of a quality present in an individual are not quite the same as one another, subsequent in various characteristics and attributes.
This is on the grounds that the two heterozygous canines have a hereditary cosmetics of (Hh). This implies that when the two canines mate, every one of their gametes has a 50/50 possibility of having either the H or h allele. By consolidating these two gametes, the posterity will have a 1/4 possibility of being homozygous for smooth hair (hh). This compares to a 25% possibility of having homozygous smooth hair posterity.

Which hormone is responsible by gene regulation?
Thyroxin hormone is responsible by gene regulation.
In general , Regulation of gene expression is mediated by thyroid hormones (T3, T4) with the help of thyroid hormone receptors (TRs). TRs are considered as the DNA-binding transcription factors that works as an molecular switches in ligand mediated responses. TRs are well versed in activating or repressing gene transcription that depends ligand-binding outputs.
Thyroxin hormone is generally inactive so they are converted to an active form called triiodothyronine with help of liver and kidneys like organs. Thyroid hormones are responsible for regulating and controlling the body's metabolic rate, heart and digestive functions, brain development and bones development.

The kind of stimulus that causes a response in a sensory receptor can be used to categorize sensory receptors. Depending on the type of cell and where it is located in relation to the stimuli it detects, receptors can be categorized structurally. On the basis of the transmission of stimuli, or how the mechanical stimulus, light, or chemical altered the cell membrane potential, they can also be categorised functionally.

Changing the temperature or pH can change an enzyme' hape. Explain how changing the temperature or pH might affect the function of an enzyme
Due to the fact that enzymes are made up of functionally-group-containing amino acid chains, the pH of a solution might have an effect on the enzyme.
By raising the bond energy, temperature impacts enzymes by forcing the atoms in the enzyme's bonds to drift apart from one another.
These functional groups are susceptible to adjustments caused by external charges. Each enzyme operates within a rather narrow pH range. There is a pH where it is most active (the optimal pH). This is due to the fact that pH variations can create and destroy intra- and intermolecular interactions, altering the structure of the enzyme and its functionality.
When certain circumstances are met, enzymes work at their best. pH, enzyme concentration, and substrate concentration are variables that influence enzyme activity. Enzyme activity is affected by temperature.

The virus is designed to deliver the functional gene into the stem cells, allowing them to produce the desired protein or other product. Once the stem cells have been “infected”, they are returned to the patient’s body and continue to produce the desired product. This allows the patient to benefit from the effects of the functional gene without having to undergo the risks of direct gene transfer into the body, such as the risk of causing an immune response.

How many days after ovulation does implantation occur?
Implantation typically occurs 6-10 days after ovulation.
Implantation is the process by which a fertilized egg attaches itself to the lining of the uterus. This process begins around 6-10 days after ovulation, when the fertilized egg, now called a blastocyst, travels through the fallopian tubes and reaches the uterus. The blastocyst then attaches itself to the endometrium, the lining of the uterus, where it begins to grow and develop. Implantation marks the beginning of the embryonic stage of pregnancy and the formation of the placenta, which provides nourishment to the developing fetus.
However, it can occur as early as 4 days or as late as 12 days after ovulation. This is because the exact timing of ovulation can vary from person to person and cycle to cycle. The timing of implantation is also affected by the timing of fertilization and the speed at which the fertilized egg travels through the fallopian tubes.
