Under very high pressure, the volume of a given object will decrease. What effect has the pressure inside Earth likely had on the density of materials in Earth’s core?
The effects the pressure inside Earth likely had on the density of materials in Earth’s core
What is Earth's pressure?It is made up of rock that is molten with slow-moving currents under the effect of increasing pressure and temperatures between 1,600 and 4,000 °F. Volcanic eruptions and earthquakes are caused by movement in the mantle layer.
Similar to how the temperature rises from the surface of the planet toward its center, so do the pressure. It is because of the heavy materials above, such as rocks.
The air density inside the International Space Station is kept at a level that is comparable to that of the surface of the planet. Consequently, the air pressure in the space station is equivalent to.
Therefore, the tremendous pressure inside Earth has the effect of reducing the volume of the materials, increasing their density.

How many seconds would it take DNA polymerase to replicate one set of human chromosomes (6,000,000,000 bytes long)
The typical human chromosome has about 150 million base pairs that the cell replicates at the rate of 50 pairs per second.
What is chromosome ?A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).
The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome is present in two forms such as Euchromatin and Heterochromatin.

what are the consequences of either an incomplete or absent ""s"" stage of the cell cycle?
Answer:
If a cell has not properly copied its chromosomes or there is damage to the DNA, the CDK will not activate the S phase cyclin and the cell will not progress to the G2 phase. The cell will remain in S phase until the chromosomes are properly copied, or the cell will undergo programmed cell death.
Explanation:
The consequences of an incomplete/absent "S" stage in a cell cycle are ;
A programmed cell death The cell will not move to the G2 phase of the cell cycleThe absence or incomplete "s" stage of the cell cycle occurs when the a cell does not completely copy its chromosomes or when there is a significant damage to the genetic material ( DNA ) of the cell. when any of these abnormalities occurs the "s" phase stage of the cell cycle will not be activated until the cell chromosomes are correctly copied. Therefore the cell will not move to the G2 phase of the cell cycle
Hence we can conclude that The consequences of an incomplete/absent "S" stage in a cell cycle are ; A programmed cell death and The cell will not move to the G2 phase of the cell cycle

Answer:
the answer is should be C
please help need asap
Answer:
The correct answer is C (The change of color allowed them to hide better from predators)
Explanation:
Before, the deer mice were easy prey for predators since their color stood out and the predators could find them. Therefore, the change of color allowed them to hide better from predators. You may be tempted to answer a, but if you read carefully it says "The change of color camouflaged them, which helped them HUNT better." Clearly A is wrong since deer mice don't really hunt.
Birds and insects both have wings, but we do not consider this similarity as evidence of relatedness because ____.
The wings in birds and insects are not considered as evidence of relatedness because they differ in structures even though their functions may be the same.
Organs in different organisms that are different in structures but similar in functions are referred to as analogous organs. Even though analogous organs serve as evidence of organic evolution, they are indications that organisms differ in the paths taken to evolve.
Some other organs may be similar in structures but different in functions. These types of organs are known as homologous organs and are indications that organisms are kind of related in the path taken to evolve.

What is the relationship between the light-dependent and light-independent reactions of photosynthesis
Answer:
In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.

Explanation:
One gene in the human genome may be expressed at a much higher level than another. Can differences in types of cis elements present account for this
Answer:
No, CREs usually don't account for differences in gene expression levels.
Explanation:
Cis-regulatory elements (CREs) are non-coding DNA regions that regulate adjacent gene transcription. They usually do it by binding to transcription factors. They are in charge of influencing the rate of which transcription occurs, and less with how much a gene is expressed. On the other hand, trans-regulatory elements are DNA sequences that encode for upstream regulators that can modify or regulate gene expression levels.
Therefore, cis elements are not really in charge of expression levels, mostly transcription rates of single genes, rather. Trans elements are more involved in expression levels.
What must happen to a chromosome for it to become chromatin?
Answer:
Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5). ... However, when eukaryotic cells are not dividing — a stage called interphase — the chromatin within their chromosomes is less tightly packed.

4. Which areas seem to be most highly and quickly affected by a continued increase in
carbon emissions?
Answer: The atmosphere will be hit hardest by the increase in carbon. As the amount of carbon increases, it leads to increased warming of the atmosphere. Rising temperatures also increase the rate of evaporation, creating a more humid atmosphere and creating a virtuous cycle of warming.
This increase is beneficial as the Earth freezes due to the absence of carbon dioxide and other greenhouse gases in the air.

The body is supported by its skeletal structure. It gives the body form, motion, and shape while safeguarding delicate organs. The body is supported by its skeletal structure.
What is skeletal system?The main structural component of your body is the skeletal system. It is made up of bones and connective tissue, such as ligaments, tendons, and cartilage.
Vertebrates are creatures with a spinal column or backbone, including humans. They are supported by a strong internal framework that is built around a noticeable spine.
Our bodies' living bones use oxygen and release waste products throughout metabolism. They have functional tissues that require nutrients, blood flow, and the ability to remodel or change shape in response to changes in mechanical stress.
The skeleton, which is made up of bones, acts as a rigid framework to support and shield the body's soft organs.
