The non-cognitive disturbances that Mrs. W. could have related to some dementia are psychosis, personality change, lack of rhythm, deficit in emotional responses, mental confusion.
It is important that the patient in these conditions is continuously assisted, to avoid situations that put her safety at risk.
An elderly woman like Mrs. W, who already has significant evolution of non-cognitive disorders, must have an effective medical apparatus and a tutor willing to help with care and daily activities.
Ideally, caregivers should develop optimal communication skills for patients with these disorders, such as a calm and gentle tone, provide the individual with a peaceful environment without too much noise or other disturbances, as well as being considerate and not neglecting the individual's needs.

regulation of the cell cycle is dependent on cyclins and cyclin-dependent kinases. the key that allows a cell to progress beyond the restriction point is
The key that allows a cell to progress beyond the restriction point is the phosphorylation of specific proteins (for example RB) by Cdk. The cyclin-dependent kinases (CDKs) are able to phosphorylate different substrates.
Cyclins regulate the progression of the cell cycle by their interaction with cyclin-dependent kinases (Cdks).
This binding activates the Cdks, thereby converting them into functional enzymes that phosphorylate target proteins and thus regulate cell cycle progression by bypassing restriction points of the cell cycle.
CDKs can phosphorylate different substrates by transferring phosphate groups from adenosine triphosphate (ATP) to specific amino acidic residues in these substrates.
For example, CDKs phosphorylate Rb proteins and thus regulate their activity during the cell cycle.

Given the number of blood vessels in the retina, why do you suppose that you are not able to see them normally
Answer:
You can't see the blood vessels themselves because vision depends on a process that makes it impossible to see things that are stationary with respect to the retina. Light receptors in the retina respond only to changes in light reaching them, not to a steady image.

what needs to occur for a fluorescent mineral to give off light?
Fluorescent minerals contain particles in their structure known as activators, which respond to ultraviolet light by giving off a visible glow.

The type of fibers specialized to continue contracting for extended periods of time, as would be required in running a marathon, for example, are _____ fibers.
The type of fibers specialized to continue contracting for extended periods of time, as would be required in running a marathon, for example, are slow fibers.
Slow fibers have numerous mitochondria that allow you to obtain large amounts of energy aerobically.
Its contraction speed is slow, providing it with high resistance to fatigue, thus maintaining exercise for hours, typical of endurance sports (marathon).They are able to retain a longer duration of exercise at a more constant pace. These fibers are important for endurance triathletes, those who compete in medium and long distance.Therefore, we can conclude that the type of fibers specialized to continue contracting for extended periods of time, as would be required in running a marathon, for example, are slow fibers.

why would you not use green light and white light if you wanted to determine the dependence of specific color wavelengths on the rate of photosynthesis?
Given our understanding of the situation, we can confirm that the use of green or white light would not be ideal for the experiment at hand because it will not yield any useful information.
In this experiment, we wish to determine the dependence of specific color wavelengths on the rate of photosynthesis. The use of white light for this experiment will defeat the purpose, given that white is the naturally occurring color of light and the available data on this is vast.
Furthermore, we would not use green colored light because it will not be effective. The effectiveness of the color of light that we decide to use will be based on the absorption rate of the light at a cellular level. Green light is known to not be well absorbed by the chlorophyll of plants and therefore will not be useful.

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”.

Choose all that apply. Which of the following is true in a comparison of your skin cells to your kidney cells?
1) conduct translation differently
2) contain different DNA
3) contain different chromosome
4) transcribe many different genes
5) conduct replication differently
6) have different transcription factors
7) contain different genes
Given our understanding of the mechanisms behind genetic expression, we can confirm that when comparing skin cells to kidney cells, the only correct option is option 4 which states that the cells "transcribe many different genes".
The human genome encodes for every gene in the human body. This genome sequence is stored in the chromosomes of cells. These chromosomes are identical for every single cell in the human body. Therefore, every cell contains the same DNA, genes, and transcription factors in its chromosomes.
What allows each cell type in the human body the ability to differentiate from one another and complete vastly different functions is the way in which these genes are expressed. Though every cell contains the entire genetic code, only some genes for each cell are transcribed, which results in a different combination of proteins in each cell and leads to the difference between skin and kidney cells (as just one of many examples).

What are homologous organs?Homologous organs are organs that share similar structural organization. They are similar structurally but are different in functions. They share common ancestors. These organs are anatomically similar. As there are common ancestors, this type of evolution is known as divergent evolution.
The reason behind the divergent evolution is environmental changes, and food requirements which force them to evolve according to the requirements. The wings of bats, the forearms of humans, and the front legs of the horse are a few examples of homologous organs which underwent divergent evolution.

What arctic animals will climate change affect? How will it affect these animals? (Site 1).
Answer: Narwhals, polar bears, and walruses will be affected the most.
Explanation:
Polar bears: The Arctic is warming about twice as fast as the global average, causing the ice that polar bears depend on to melt away. Loss of sea ice also threatens the bear's main prey, seals, which need the ice to raise their young.
Narwhals: The Narwhal's Arctic habitat is highly sensitive to climatic changes that result in increased atmospheric and ocean water temperatures. The Narwhal's annual migration from the north in summer to more southerly overwintering habitats exposes them to sea ice which is constantly expanding and receding. Because of the sea ice rapidly decreasing, narwhals could be exposed to new threats and noises.
Walruses: Habitat loss will be exacerbated for walruses by additional climate-change related factors such as ocean acidification, increased shipping and increasing development in the North, including oil and gas extraction, as well as increased disease and contaminant risks. biggest threat facing walruses is the loss of stable sea ice due to climate change. As a result of less sea ice, walrus are changing their behavior. Walruses feed on the ocean floor in the relatively shallow waters of the continental shelf, where the sea ice itself sustains a rich food web.
