_______ 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.

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.

Our sun is a low mass main sequence star at the middle of its life cycle. Explain how the
appearance of the sun's location on the HR diagram will change as it continues to the end of
its life cycle.
Answer:
Accordingly, when our Sun comes up short on hydrogen fuel, it will grow to end up a red monster, puff off its external layers, and after that settle down as a minimal white small star, at that point gradually chilling off for trillions of years. All incredible, in the long run — in around 5 billion years — our sun will, as well. When its supply of hydrogen is depleted, the last, sensational phases of its life will unfurl, as our host star extends to wind up a red Goliath and afterward shreds its body to consolidate into a white smaller person Explanation:

Why are common cold viruses difficult to cure?(1 point)
A copy of the DNA is made from the viral RNA.
The virus leads to other viral infections such as the flu and HIV.
The viral genome mutates very quickly.
Vaccines prevent the development of a cure.
Answer:
You are very correct the answer is c
Correct option is ''The viral genome mutates very quickly.''
Viruses can't reproduce on their own as bacteria do, instead, they attach themselves to healthy cells and reprogram those cells to make new viruses. It is because of all of these differences that antibiotics don't work on viruses. Antibiotics and medications treat bacterial infections. These antibiotics cannot treat or cure a common cold as colds aren't caused by bacteria.
Common cold viruses are difficult to cure as the viral genome mutates very quickly.

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.

What health-related careers would be of most interest to you? How would learning more about anatomy be helpful for that career?
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).
