Explanation:
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:

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.

Describe any other local examples of relationships between organisms that may influence population numbers?
Answer: trees, flowers, bees
Explanation:
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).

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.

Scientists can study the human genome using DNA fingerprinting.
DNA fingerprinting allows scientists to
B. break the hydrogen bonds in a gene to allow DNA to replicate itself.
c. determine the location of an abnormal gene on an individual's
chromosome.
A. prevent a gene from matching complementary bases onto a strand of
RNA.
Answer:
your answer is C.
Explanation:
DNA fingerprinting allows researchers to determine the location of an abnormal gene in a person's chromosomes.
What are the steps in DNA fingerprinting?DNA fingerprinting is a laboratory technique used to determine the likely identity of a person based on the nucleotide sequences of certain regions of a person's DNA that are unique to individuals.
DNA fingerprinting was used early in legal disputes, particularly in solving crimes and establishing paternity. It is also used to detect inherited genetic diseases and can be used to identify genetic matches between tissue donors and recipients.
In DNA fingerprinting, researchers collect DNA samples from various sources, such as hair from crime scenes and blood from victims and suspects. They then narrow down scattered sections of repetitive DNA in these samples.

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:

_______ 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.

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.
