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.

Answer:
I, II, and III.
Explanation:
Immune response may be defined as the type of response generated by the body against the pathogens. The immune response is important to kill the pathogens.
Fever is a type of immune response generated to kill the pathogen by increasing the body temperature. The number of white blood cells of the body increases to fight against the pathogen. The inflammatory response may also generated to kill the pathogen.
Thus, the correct answer is option (E).
what is located in the autonomic nervous system
Answer:
It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.
Explanation:
The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS) contain both afferent and efferent fibers that provide sensory input and motor output, respectively, to the central nervous system (CNS). Generally, the SNS and PNS motor pathways consist of a two-neuron series: a preganglionic neuron with a cell body in the CNS and a postganglionic neuron with a cell body in the periphery that innervates target tissues. The enteric nervous system (ENS) is an extensive, web-like structure that is capable of function independently of the remainder of the nervous system. It contains over 100 million neurons of over 15 morphologies, greater than the sum of all other peripheral ganglia, and is chiefly responsible for the regulation of digestive processes.

Why Is Biodiversity Important? Who Cares?
Name three biological services provided by
biodiversity
Biodiversity has been defined as the life that lives and interacts within the ecosystem. It is important as provides proper functioning of the ecosystem and supports life on earth.
What is Biodiversity?Biodiversity is the various forms of life and factors that live and exhibit interaction in a particular ecosystem and habitat. It is important as it includes the biogeochemical cycle that provides nutrients, ecosystem services, pollination, and reproduction.
Biodiversity provides various biological services, including food produced by plants for energy, oxygen for cellular respiration and photosynthetic reactions, and the biogeochemical cycle that includes the cycling of the nutrient through various spheres.
Therefore, biodiversity is an important part of the biosphere.

what specific type of tissue makes up the intervertebral discs
Answer:Fibrocartilage
Explanation:
Name the 2 different types of endoplasmic reticulum and explain the function of each type endoplasmic reticulum to the cell . (ie - what does each one 'produce', or make for the cell)
Answer:
The surface of the rough endoplasmic reticulum (ER) is covered in ribosomes, while the smooth endoplasmic reticulum is not covered in ribosomes.
Explanation:
Hence their terms, rough and smooth endoplasmic reticulum, the smooth is like a fine tube whereas the rough consists of ribosomes on its surface. Both the smooth and rough endoplasmic reticulum work together, delegate tasks and are the site for production and storage of proteins.
Smooth ER is responsible for storage and lipids production, while the rough ER is responsible for production of proteins and some hormones.

what is the effect of telomere caps on cancer cells?
The telomere caps help to maintain genome integrity. In consequence, these repetitive sequences are fundamental to avoid the generation of cancer cells.
Cancer cells are a type of cells that proliferates in an uncontrolled manner, which is generally associated with mutations in the genome capable of altering normal gene expression patterns.
Telomere caps are repeated nucleotide sequences found at the end of chromosomes, which help to maintain genome integrity.
The elimination of these repetitive sequences (telomere caps) due to successive cell divisions triggers chromosomal (genome) instability and thus contributes to the emergence of genomic rearrangements that may lead to carcinogenesis.

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.
