Tumor suppressor proteins are the regulatory proteins that prevent cells from entering the s phase under conditions of DNA damage.

What are regulatory proteins?

These are the proteins that interact with RNA polymerase and affect the role of transcription. These proteins bind to regions near the promoter where the RNA polymerase binds to initiate the transcription of DNA to mRNA.

Tumor suppressor protein acts to inhibit cell proliferation and tumor development. These cells slow down cell division and make cells die at the right time (apoptosis or programmed cell death).

Retinoblastoma protein was the first tumor suppressor protein that plays a central role as a negative regulator of the cell cycle. These proteins are used mostly for the reduction of cancer by inhibiting the growth of tumor cells through apoptosis. Mostly they block the cell cycle at the g1(gap 1) phase.

Van Helmont in his experiment concluded tried to answer that the plants growth does not only depend upon the minerals present in the soil as he observed there was no change in the mineral content of soil however the plant gained 75kgs weight.

Van Helmont planted a tree, watered the tree and then left it for 5 years. He then re-weighed the tree after 5 years, which had its mass increased by over 12 stones. He then dried the soil and weighed it again, showed that the mass of soil was almost the same. He then concluded that the tree grew by drinking water and not only by the minerals present in soil.

Bumblebees are thought to be descendants of hunting bees that developed a taste for honey and chose a vegetarian diet.

Bumblebees may have evolved on Earth at the same time as flowering plants during the Cretaceous period, 146-74 million years ago, but fossil evidence is scant.

How have bumblebees changed?

Bumblebees are accustomed to cold weather, so they are often seen in the cold. This indicates that they have specific adaptations. The most prominent among them is thick, fluffy hair. It's to keep you warm in cold weather. Because of these adaptations, they may also become unable to cool off in hot climates.

About 30 to 40 million years ago, the first Bumblebees invaded the giant's realm. This coincided with a period when the weather was colder, which may have resulted in larger, hairier bees.

Bumblebees looks up to Optimus as a mentor and father. They had previously worked together during the conflicts on Earth and Cybertron.

The genotype of the cross is 50% Aa and 50% aa.

The phenotype of the cross is 50% side flower and 50% end flower.

The problem here has to do with a crossing involving a single gene. That is a monohybrid cross. Crosses involving two traits are known as dihybrid crosses.

Let us assume that the side flower allele is represented by A (since it is the dominant allele) and the end flower allele by a (the recessive allele). The dominant allele masks the expression of the recessive allele when they are together.  Hence:

The genotype of a homzygous recessive plant = aa

The genotype of a heterozygous plant = Aa

Crossing Aa and aa:

                 Aa    x    aa

            Aa   Aa   aa   aa

The genotype of the offspring from the cross:

    = 50%(1/2) Aa and  50% (1/2) aa

The phenotype of the offspring from the cross:

    = 50% Aa (side flowered) and 50% aa (end flowered)

Thus:

The order of information flow from the primary sensory afferent to the lower motor neuron is option(a) i.e, dorsal root ganglion, dorsal horn, ventral horn.

The nerve fibers that carry sensory data from the outside environment into the brain are known as afferent neurons, also referred to as sensory afferent neurons. Special senses like vision, hearing, smell, or taste, as well as the senses of touch, pain, and temperature, can all play a role in sensory information.

The signal from the higher motor neuron is sent to the effector's muscle by the lower motor neuron, which then causes the muscle to move. Somatic motor neurons, specific visceral efferent (branchial), and generic visceral motor neurons are the three main subtypes of lower motor neurons.

PCOS with full meaning "Polycystic Ovarian Syndrome" is a common disorder of the endocrine system that is diagnosed based on inclusion criteria of an ovulation or oligo–ovulation, presence of polycystic ovaries on ultrasound. From research, it has shown that many women with PCOS also have hyperinsulinemia, leading to over production of ovarian androgens. This has led to several studies on the use of the insulin–sensitizing agent metformin in inducing ovulation in women with PCOS. Metformin combined with the fertility drug clomiphene citrate (clomid) has shown to be more effective than the placebo in stimulating ovulation. While metformin has not yet gained the title of a first–line pharmacological agent for ovulation induction, research shows it has many benefits in PCOS treatment.

Additionally, G protein mutations can result in either a loss or gain of function by inhibiting or stimulating signal transduction, which, in turn, results in the clinical phenotypes of an excess or a deficiency of hormones.

The alpha subunit switches its GDP for a GTP when the neurotransmitter dopamine activates the receptor. The G protein subsequently breaks down. The beta and gamma subunits are left behind when the alpha subunit, which is carrying GTP, moves away.

The state of the receptor is altered when a ligand known as an agonist stimulates it. In order to activate G alpha, GTP must be exchanged for the bound GDP after G alpha separates from the receptor and G beta-gamma. The next step for G alpha is to activate more cell molecules.

Mendel spent eight years researching heredity through the use of the simple-to-breed pea plant (Pisum sativum). He crossed the plants and performed hybridization studies on approximately 29,000 plants, which allowed him to change 7 of the plants' obvious traits: plant height, pod shape and color, seed shape and color, and bloom position and color.

He did this by applying pollen with a paintbrush. He is now regarded as the founder of modern genetics, despite the fact that it was decades after his death that his discoveries were confirmed. He wrote about the invisible "factors"—what we now refer to as "genes") that determine apparent features in his 1866 publication.

Answer:Cellular Respiration

Explanation:

Cellular respiration is the process by which cells produce energy, and is broken down into three more steps: glycolysis, Kreb’s cycle, and electron transport chain. Glycolysis requires glucose, two ATP, and NAD+, and two ADP, and produces two pyruvate, four ATPs, two NADH, and two H2O. The Kreb’s Chcle and thus the downstream electron transport chain require acetyl-CoA, one ADP, three NAD+, and one FAD, but pyruvate oxidation needs to happen prior to the Kreb’s Cycle, thus this is where the Oxygen is used and produced into two CO2.
