The four types of final impression materials are: 1) inelastic impression materials, 2) elastomeric impression materials, 3) hydrocolloid impression materials, and 4) inorganic impression materials.

Inelastic impression materials, which include plaster and compound materials, seem to be the least desirable to use as final impression materials. These materials are rigid and lack flexibility, which makes it difficult to obtain accurate impressions of complex oral structures, and they can also cause discomfort for patients during the impression process.

Elastomeric impression materials, hydrocolloid impression materials, and inorganic impression materials have largely replaced inelastic materials due to their improved accuracy and ease of use.

Asexual reproduction is a type of reproduction that does not involve the fusion of two gametes. Since this reproduction does not involve the fussion of two different cells there is no genetic mingle and the resulting organisms are genetically identical to the parent.

Prokaryotes are unicellular organisms that reproduce by mitosis, which is a form of asexual reproduction. So, for this organisms, the individuals are genetically identical.

Sexual reproduction involves the fusion of two gametes of two individuals, the resulting offspring is produced by the combination of the genetic information of both parents. This type of reproduction generates individuals that are genetically different than its parents. During meiosis, occurs genetic recombination, which after many generations, leads to the change and evolution of the species.

Eukaryotic organisms reproduce by this method. This means that these organismsn are more likely to evolve complex structures over the millions of years.

The correct option is A.

Explanation:

Homeostasis is a phenomenon which involves the ability for an organism to maintain a stable internal environment despite fluctuations in the external environment. Homeostasis is important for the survival of living organisms as their cellular functions depend on it.

One of these environmental conditions is heat/hot temperature. Animals need to maintain a stable internal internal temperature despite the change in environment's. Animals do this by cooling down via various ways which include the following:

- Animals like apes, primates possess sweat glands like humans and hence cool down by SWEATING

- Animals like dog quickly exhale hot air and bring in cool air in a process called PANTING to cool down.

- Production of GOOSEBUMPS in animals help their hairs to stand in adverse weather conditions

Note that bird flap their wings in order to support flight and not perform an homeostatic process like cooling down.

Answer:

cellular membrane

Explanation:

cellular membranes — including plasma membranes and internal membranes — are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains. Glycerol is a three-carbon molecule that functions as the backbone of these membrane lipids.

Answer:

50%

Explanation:

Let's make a Punnett square to represent this, with X representing our dominant allele and x our recessive.

One homozygous dominant parent = XX

One heterozygous parent = Xx

      X    X

X   XX  XX  

x    Xx  Xx

So two out of our four outcomes are heterozygous for the trait. That means the answer is B. 50%.

The probability the offspring will be heterozygous for this trait is 50%

Heterozygous is the presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles.

If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair.

To be heterozygous for a trait is to have different alleles for it. Being homozygous for a trait means that it will always turn out the same.

When a cell undergoing cellular division identifies that a chromosome misalignment had taken place the cell cycle stops until the error it's corrected.

Option two of the question states that the cell cycle will proceed uncontrollably, this is not the case for the error at hand. Although this can be a problem for cells and leads to the appearance of cancer, it is not caused by chromosome misalignment. As is the case with options 3 and 4.

The stop or delay in the cell cycle is what normally takes place in these situations. This stoppage is done by the spindle checkpoint, which prevents duplicate chromosomes from separating.

During this time, the error it's corrected. If a cell is not able to correct the error at this time, many situations can follow. However, the most likely is that the cell will undergo a programmed cellular death.

Answer:

Hotspot (B)

2nd one (button)

The answer is Option a, concentration of dissolved salt in the solution is greater than the concentration in the cells. Here the statement describes the characteristics of a hyper-tonic solution.

In comparison to another solution, a hyper-tonic solution has a higher solute concentration. The hypo-tonic solution is the opposite solution with a lower concentration. Scientists must compare the contents of cells to their surroundings. A cell is said to be hypo-tonic if it is placed in a hyper-tonic solution.

The environment is hypo-tonic, or more weakly concentrated, if the cell's cytoplasm is a hyper-tonic solution. Due to the fact that solutes and water have a tendency to diffuse or flow along gradients, this is extremely important. One solution will eventually result from the combination of two solutions.

The solutions will become isotonic when the water passes between the two solutions if the solutions are separated by a permeable barrier that only enables water to pass through. Despite having varying volumes, isotonic liquids have the same concentration.

The electrical activity of these cells relies on the positive and negative charges of the ions in the hyper-tonic solution.

Hyper-tonic Solution Examples

1. Human Kidney

The human brain contains unique proteins called osmoreceptors that are able to gauge the osmolarity of the environment surrounding the cell in order to control the amount of water in the body. Because there isn't enough water in the blood to hydrate the solutes, the environment can become a very hypertonic solution.

2. Sea Turtle Osmoregulation

Salt water is a solution that is more hyper-tonic than fresh water. This suggests that a cytosol that is more hyper-tonic than salt water is required for cells to operate. In contrast to freshwater turtles, sea turtles, for instance, live in a considerably more hypertonic environment.
