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.

In the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are: more sensitive in the dark than cones.
The retina extends through the posterior portion of the eyeball is the innermost layer and in it are the photoreceptors: cones and rods.
Rods and cones are the two types of photoreceptor cells in vertebrates that capture light energy (photons) and convert it into electrical signals.
The rods are sensitive to changes in light, since their detection thresholds are low, so they only come into operation when the light intensity is low (scotopic vision or night vision).Scotopic vision has relatively low acuity, as the details of an object cannot be discerned or its color appreciated.On the contrary, cones have a much higher threshold for light, they are responsible for daytime vision (photopic vision) and their mission is to detect colors and shapes (details).Therefore, we can conclude that in the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are: more sensitive in the dark.

_______ are a result of hurricanes, which push massive amounts of water inland, causing severe damage.
Answer:
Warm ocean air rises into the storm
Explanation:
Most of us know that heat rises so when the heat from the ocean rises it adds into the storm and creates a low-pressure area under the clouds which then continues to build heat and the winds reach to around 74 MPH to be classified as a hurricane.

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.

Answer:
hypothalamus
The part of the diencephalon that is in the anterior and inferior region of the diencephalon is the Hypothalamus.
What is Hypothalamus?The hypothalamus exists a portion of the brain that includes a numeral of small nuclei with a combination of functions. One of the most important operations of the hypothalamus exists to link the nervous system to the endocrine system via the pituitary gland. The hypothalamus exists discovered below the thalamus and exists as part of the limbic system. The terminology of neuroanatomy, includes the ventral part of the diencephalon. All vertebrate brains include a hypothalamus. In humans, it stands the size of an almond.
The hypothalamus stands answerable for the regulation of specific metabolic functions and other actions of the autonomic nervous system. It synthesizes and secretes certain neurohormones, named releasing hormones or hypothalamic hormones, and these, in turn, promote or inhibit the secretion of hormones from the pituitary gland. The hypothalamus influences body temperature, hunger, important aspects of parenting and affection manners, thirst, fatigue, sleep, and circadian rhythms.
Hence, The part of the diencephalon that is in the anterior and inferior region of the diencephalon is the Hypothalamus.

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”.

Why do fossils that paleontologists find represent only a partial picture of life in the past?
Answer:
Because we cannot see some animals properly like jellyfish as their tissue is too soft, and feathers or for can often not make an imprint on fossils.
Explanation:
Answer:
Fossils: They are remains of animals or plants in the past that were somehow preserved and buried under the earth's crust.
One fossil can only give us a glimpse into the history of the time that particular animal or plant lived or breathed on the earth. For example, a fossil remains of a particular species of dinosaur would only provide information of the time when that species lived on earth and other information related to that particular time. Fossil remains of dinosaurs would not give us information on the time during the ice age or any other time in history.Explanation:
The study of various fossils can give us information about the development and evolution of living organisms over time but there are limitations to it.It may happen if we compare the fossil remains of an organism that existed billions of years ago we may find a time gap where there is no fossil evidence found so it creates a loop in information.Also, the process of fossilization is complex and long. Many species of the past became extinct without fossilization so we can never get information related to those extinct species.Thus, because of this reason we can say that fossils don't provide us with complete information about the past.For more information:
