Hey there!
We have the three states of matter, labelled in the picture, called gases, liquids, and solids.
But did you know that there are terms and explanations as to how a material's state can change?
Gases changing into a liquid is called condensation. This occurs when warm air collides with cold surfaces, making the cold surface 'sweat' from the warm air. We see this in the early mornings when the sun starts cooling up the grass, which was colder because of the night.
Liquids changing into a gas is called vaporization. This occurs when liquids are usually approached to a high enough temperature in which it exceeds their boiling point, and the tighter liquid molecules drift off wandering around. When molecules wander around enough, they can vaporize and turn into a gas.
Liquids turning into a solid is called freezing. This happens because in colder temperatures, molecules cannot move as quick because they are mimicking their environment; they actually clump up together because they are cold (think about it as them warming themselves up with each molecules around them!) and become a solid.
Solids turning to a liquid is called melting. When something at it's freezing point (when it is a solid) and it loses that freezing point and gets warmer, the molecules can now move around much more freely, which means that it can become a liquid.
Solids turning into a gas is called sublimination. Think of the snow droplets turning into water vapor immediately in the air. This is an example of sublimination, where a good amount of heat is given and skips the liquid phase.
Gas turning into a solid is called deposition. We already thought about the snow; so let's think of the water vapor turning into snow in the air, the opposite reaction; this is due to the excessively extreme cold air that was given to the water vapor that made it skip the liquid phase.
In this problem, we see that a block of ice is turning into water.
We can conclude that it is turning from a solid to liquid.
However, why does this occur? Like we learned before, this process is called melting; and this occurs when something that was colder than water's freezing point (32°F or 0°C) is applied warmth (which is energy) from the air to the ice, the ice will melt into a liquid. The molecules are no longer constricted to this firm slow movement and can freely move around.
Therefore,
1. The ice will melt because the air is too warm to sustain the ice's climate.
2. This happens because since the climate is presumed to be above the water's freezing point, the ice will no longer be able to maintain it's phase.
3. The ice left out would be a phase change of solid to liquid.
4. This phenomenon is called melting.

which medical imaging technique do you find most interesting? why?
Answer:
Patrick De Potter, in Clinical Ophthalmic Oncology, 2007
Content
Information on the content of the lesion (cystic or solid; homogeneous or heterogeneous) can be obtained by both CT and MR imaging techniques. Both techniques also detect the presence of fluid–fluid or fluid–air levels. When lesion density is higher than that of the vitreous, CT images identify the lesion as solid. As wide range of tissue densities on CT scans or signal intensities on MR images relate to the internal architecture and the presence of proteinaceous or blood products, it is not always possible to differentiate a solid from a cystic orbital lesion. MRI images identify tissue compounds such as melanin, methemoglobin, deoxyhemoglobin, ferritin, and proteinaceous material. Punctate or conglomerate increased densities on CT scans or foci of signal void on MRI may be seen in trauma, vascular tumors, optic nerve sheath tumors (meningioma), epithelial lacrimal gland tumors, and malignant osseous tumors (osteosarcoma). In general, MR images provide more information about the content of the lesion and than do CT images. However, CT is best suited for the detection of calcification.

2. What is the importance of NAD+ cycling back up to glycolysis?
The cycling of NAD+ back up to glycolysis is crucial for sustaining energy production, maintaining redox balance, and allowing for the efficient functioning of cellular respiration.
The cycling of NAD+ back up to glycolysis is crucial for the efficient functioning of cellular respiration and energy production. Here are the key reasons for its importance:
NAD+ regeneration: During glycolysis, glucose is metabolized to produce energy in the form of ATP. As part of this process, NAD+ acts as an electron carrier, accepting electrons from glucose and becoming reduced to NADH. NADH carries these electrons to the electron transport chain for further ATP synthesis. However, NAD+ is required to sustain glycolysis. Without a mechanism to regenerate NAD+ from NADH, the glycolytic pathway would quickly halt due to a lack of available NAD+. Therefore, the cycling of NAD+ is crucial for maintaining a continuous supply of NAD+ for glycolysis.ATP production: The regeneration of NAD+ is directly linked to ATP production. NADH carries high-energy electrons to the electron transport chain, where they are used to generate ATP through oxidative phosphorylation. If NADH accumulates and NAD+ levels decrease, electron transport and ATP synthesis would be compromised, resulting in reduced energy production.Redox balance: The cycling of NAD+ is essential for maintaining redox balance within the cell. As NAD+ accepts electrons during glycolysis, it becomes reduced to NADH. Regenerating NAD+ from NADH helps balance the cellular redox state, ensuring that other redox reactions in the cell can proceed smoothly. Without NAD+ cycling, an imbalance in the redox state could lead to disruptions in various metabolic pathways and compromise cellular function.Learn more about Glycolysis, here:

fitness is a measure of reproductive success. if an individual with genotype (bb) produces 6 offspring, and a heterozygous individual (bb) produces 10 offspring, and a third individual with genotype (bb) produces 5 offspring, what is the fitness value for the individual with (bb) genotype?
Reproductive success is measured by physical fitness.Natural selection can affect polygenic traits or qualities determined by different alleles of a single gene.
Is fitness is a measure of reproductive success?
Natural genetic variations among members of the same species are referred to as genetic variation.A population can adapt and survive in the face of shifting environmental conditions thanks to this variety. The fitnesses are just each survival rate divided by the highest survival rate if only survival rates vary and reproduction rates are all identical.Fitness is equal to each reproductive rate divided by the highest reproductive rate if only the reproductive rates vary and the survival rates are all identical. The type of variant present at a specific locus (i.e., region) in the genome is scored by what is known as a genotype.Symbols can be used to symbolize it.For illustration, BB, Bb, and bb could be used to denote a certain gene variant. Even though we are thinking about how selection affects genotypes, we can still compute an allele's average fitness (also known as the marginal fitness) by dividing the likelihood that an allele would occur in a certain genotype by its fitness. The quantity of viable progeny that an organism produces is the best indicator of its fitness.Fitness is a key indicator of reproductive success since it leads to more children, who in turn add more genes to the gene pool for the following generation.Typically, subjects like evolutionary biology will utilize this word.
