Smallest to Largest:
1. Nucleotide
2. Gene
3. Chromosome
4. Genome
Nucleotide, Gene, Chromosome and Genome is the levels of genetic information in order from smallest to largest.
What is Chromosome?Chromosomes are the thread-like structure made up of protein (histones) and a single molecule of DNA which carries all the genetic information in it. It is located in nucleus.
Human have 23 pairs of chromosomes including pairs of 22 chromosomes (i.e. Autosomal Chromosomes) and 1 pair of Sex Chromosome (XX or XY).
Each pair contain two Chromosomes inheriting from the parents, half from mother and another half from the father.
Each chromosome have a point which is constricted in the middle known as Centromere, which divides chromosomes into two arms i.e. short arm “p” and long arm “q”.
Thus, Nucleotide, Gene, Chromosome and Genome is the levels of genetic information in order from smallest to largest.

A(n) ______ gene is a type of gene that regulates development and that, when mutated, leads to organisms with structures in abnormal or unusual locations on their body.
A (n) homeotic gene is a type of gene that regulates development and that, when mutated, leads to organisms with structures in abnormal or unusual locations on their body.
A homeotic gene is a gene that intervenes in the developmental program that determines the location of structures along the anteroposterior axis.
The determination of the anteroposterior axis is one of the earliest events in development, and it guides the remaining processes of organogenesis. Once homeotic genes define the identity of the body segments, they code for proteins (homeodomain) that are responsible for activating other genes.These genes ultimately trigger the formation of the organs or limbs of this segment.Genes that control the position of organs have been called homeotic genes, while mutations that affect these genes are known as homeotic mutations.Therefore, we can conclude that homeotic genes are expressed in the body regions that will house the growing structures.

The smooth endoplasmic reticulum is different from rough endoplasmic reticulum as the rough endoplasmic reticulum has ribosomes attached to its surface which are absent in smooth endoplasmic reticulum. Thus, the correct option is C.
What is Endoplasmic reticulum?
Endoplasmic reticulum (ER) is a large, dynamic structure which serves for many roles in the cell. There are two types of ER which are Smooth Endoplasmic Reticulum (SER) and Rough Endoplasmic Reticulum (RER). The diverse functions of the ER are performed by distinct domains present in the ER consisting of tubules, sheets and the nuclear envelope.
Rough endoplasmic reticulum contains ribosomes on its surface and synthesizes protein, whereas the smooth endoplasmic reticulum does not contain ribosomes and functions to make lipids and detoxify the cell. Large amounts of SER are found in the cells which participate in lipid metabolism and detoxification of the body, such as liver cells.
Therefore, the correct option is C.

how can one eukaryotic gene lead to one transcript, but multiple different proteins?
Answer:
source- The ability of certain genes to form multiple proteins by joining different exon segments in the primary trans-cript is called alternate splicing and has caused a reexamination of the concept of “one gene, one protein.
Scientists have long known that it's possible for one gene to produce slightly different forms of the same protein by skipping or including certain sequences from the messenger RNA. ... Human genes typically contain several "exons," or DNA sequences that code for amino acids, the building blocks of proteins.
in your own words-
the flexibility of bound factors to make multiple proteins by connection totally different DNA segments within the primary trans-cript is termed alternate junction and has caused a reexamination of the thought of “one gene, one macromolecule.
Scientists have long noted that it's attainable for one factor to provide slightly totally different styles of a similar macromolecule by skipping or together with bound sequences from the informational RNA. ...

Answer:
Sensory receptors respond to stimuli.
Explanation:
They can be classified by their location, the type of stimulus they detect or by their structural complexity.
Sensory receptors are the receptors which respond to stimuli within the
body. The body have five major sensory organs which include the eyes,
nose, tongue, ear and skin.
These organs have receptors which is responsible in the transmission of
signal to the brain for action. The brain acts depending on the signal
received which is usually in the body's best interest.
This makes our sensory organs important and very delicate and as a result

How does a mutating virus impact vaccinations? What would happen to the effectiveness of the current vaccination if a mutation in the virus caused the protein spike to change?
A vaccine is a medical product. Vaccines, though they are designed to protect from disease, can cause side effects, just as any medication can. When a virus is widely circulating in a population and causing many infections, the likelihood of the virus mutating increases. The more opportunities a virus has to spread, the more it replicates – and the more opportunities it has to undergo changes. Most viral mutations have little to no impact on the virus’s ability to cause infections and disease.

Certain genes are turned on and others are turned off; this action produces adult cells that are specialized
As a cell matures, genes that are not necessary to its function are ejected out of the cell through active transport.
The number of chromosomes in the cell is reduced by half; this action triggers the specialization of the cell.
A developing cell's function is determined by the number of organelles that are contained in the cell.
Through the mitotic process, two identical diploid daughter cells are produced. Mitosis is preceeded by the interphase and followed by cytokinesis. 7) b. / 8) a. / 9) b. / 10) b. / 11) c. / 12) a.
-------------------------------------------------
The interphase occurs before cell division. It is composed of the G1, S, and G2 stages.
During the G1 stage, the cell duplicates in size. The organelles and other cytoplasmatic structures duplicate. The high intense biochemical activity is characteristic of this stage. During the S stage occurs the DNI molecule replication process. At this point, also happens the synthesis of histones and other associated proteins. The G2 stage is the final one before the cellular division. Here begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.
Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced.
Daughter cells are identical to the original cell.
Mitosis occurs in only one phase, divided into four stages.
In the prophase, it occurs chromosomes condensation and nuclear membrane breaks. During the metaphase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes line up.Each chromatid joins with a microtubule of opposites poles.
In Anaphase, bonds between chromatids break. They separate and migrate to the opposite poles. In telophase, duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole.Finally, cytokinesis occurs.
*************************************
Now, according to this theoretical framework, we can answer the questions.
7) b. are identical to the chromosomes of the parent cell.
8) a. The information is duplicated.
9) b. Mitosis is a phase in asexual reproduction that results in the formation of identical nuclei in the daughter cells.

Neural impulses are transmitted to bipolar cells when light energy enters the eye and triggers ________ in the rods and cones.
Neural impulses are transmitted to bipolar cells when light energy enters the eye and triggers CHEMICAL CHANGES in the rods and cones. This process is known as phototransduction.
Phototransduction refers to the process by which photoreceptors convert light into electrical signals.
Photoreceptors (i.e., rod and cone cells) are specialized cells in the retina of the eye which are capable of converting light into electrical signals and thus trigger different physiological processes.
Phototransduction is triggered by the activation of signaling proteins, that open or close ion membrane channels in photoreceptor cells.
