Answer:Scientists figured out that the outer core must be liquid because S waves do not pass through it, but P waves do. The behavior of P and S waves also indicates that the inner core is solid. The speed of seismic waves also depends on the density of the material through which they are traveling.
Explanation:
The inner core of Earth is a solid which has a higher temperature and a higher pressure than the outer core of the planet. Thus, the correct option is C.
What is Earth's core?Scientists have discovered that the outer core of Earth must be liquid because of the S waves, which do not pass through it, whereas the P waves do pass through it. The behavior of P and S waves indicates that the inner core of Earth is solid. The speed of the seismic waves also depends on the density of the materials by which the waves are moving.
The pressure of the inner core is nearly 3.6 million atmosphere and the temperature of the inner core is far above the melting point of iron element. However, the inner core is solid. The inner core's intense pressure and temperature than the rest of the planet prevents the iron from melting.
Therefore, the correct option is C.

3. Explain the role of enzymes and how they affect the chemical reactions of living things.
Answer:
The role of enzymes is that enzymes are vital for life
Explanation:
Enzymes are vital because they are proteins that make the body work faster such as digestion and metabolism.
Enzymes are proteins that serve as biological catalysts by speeding up chemical processes. The enzyme is not destroyed during the reaction and is reused.
What do enzymes do ?Enzymes help with the chemical reactions that keep a person alive and well. Many key functions in the body are supported by enzymes. Here are a few examples:
The digestive system: Enzymes assist the body break down more complex molecules, such as glucose, into smaller ones that may be used as fuel.DNA replication: DNA is found in every cell in the body. When a cell divides, it must duplicate its DNA. Enzymes aid in this process by unraveling the DNA coils.Toxins in the body are broken down by liver enzymes. To do this, it employs a variety of enzymes to aid in the process of eliminating the poisons.Enzymes also aid in the following activities:

Several students were having a discussion about the role of chromosomes in inheriting traits.
Which statements made by the students provide the MOST accurate description?
[Select ALL that apply]
Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave.
Genes contain thousands of chromosomes that carry specific information about building proteins for a particular trait.
Chromosomes are small sections of DNA that contain specific information about a trait to build proteins that people inherit. The thousands of different chromosomes passed from the parents allow for humans to look uniquely different.
Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring.
Homologous chromosomes carry different gene sequences from each parent so the offspring may inherit more genes from one parent than they do from another parent.
Answer:
Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave.
Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring.
Explanation:
Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave. - this is true. Prior to cell division, DNA molecules are organized into large structures called chromosomes. Specific regions of a DNA molecule are called genes. These dictate specific proteins which control our traits.
Genes contain thousands of chromosomes that carry specific information about building proteins for a particular trait. - this is false - genes are segments of DNA that control specific traits by dictating the structure and functions of proteins. Chromosomes contain thousands of genes
Chromosomes are small sections of DNA that contain specific information about a trait to build proteins that people inherit. The thousands of different chromosomes passed from the parents allow for humans to look uniquely different. - this is false - chromosomes are large structures, genes are the relatively small sections of DNA. Humans have 23 pairs of chromosomes, not thousands.
Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring. - this is true. In diploid organisms, like humans, have two copies of each chromosome. These chromosomes contain slightly different versions of genes, which make us unique.
Which statement about cells is NOT true.
Contain substructures
O Have organelles that performs different functions
O Come together to form molecules

A ______ frequency causes a _____wavelength and ______ energy. Lesson: 4.09 Question 10 options: higher, shorter, high low, shorter, greater low, greater, shorter higher, greater, shorter
Answer:
A higher frequency causes a shorter wavelength and higher energy.
A shorter frequency causes a greater wavelength and low energy.
Explanation:
Frequency is the number of waves that move at a period of time. It is measured by counting the number of crest point.
Wavelength is the distance between waves. A wave with higher frequency have crest that a very close and therefore the distance between them or wavelength is short compare to a wave with low frequency that the distance are farther apart and they have long wavelength. Therefore to generate high frequency of wave , more energy is required to do this .

Which row in the chart correctly describes what would be expected to occur in
the potato cells, with regard to both the starch and water molecules?
Answer: A (More Water Will Move Into The Cell And Starch Will Remain In The Cell).
Explanation: No Explaining, You Got 17 Minutes Left On The Test, HURRY UP! Just Trust Me.
Answer:
Water: more water will move into the cell than will leave the cell.
Starch: Starch will remain inside the potato cell.
Explanation:
Hey there!
In this case, according to the given information, and the chart, it is possible to infer that the water molcules outside the cell will have the capacity to move inside it, via difussion, as more concentration is outside, creating a potential able to induce the process. In addition, the amount of molecules of water that get into the cell is greater than those leaving it, because of the aforementioned.
Moreover, since no starch molecules are outside the cell, there will not be any potential inducing the difusion process, for that reason these will not move anywhere.
Thus, the correct row states:
Water: more water will move into the cell than will leave the cell.
Starch: Starch will remain inside the potato cell.

During which stage of the cell cycle is the increase in nucleic acid polymers most apparent?
Answer:
The correct answer is - S or synthesis phase.
Explanation:
S phase or synthesis phase of the interphase is the phase of cell division which takes 5 to 6 hours to complete. In this phase the RNA content increases while DNA replication and synthesis takes place to provide enough genetic matter and polymer to complete the cell division.
Duplication or replication of the DNA increases the amount of nucleic acid for the successful division of the cell. S phase is the phase that prepares the parent cell for cell division.

What can be said about studying these traits?
A) The traits would not obey the law of segregation because they are always inherited separately.
B) The traits would not obey the law of independent assortment because they are always inherited separately.
C) The traits would obey the law of segregation because they are not inherited separately.
D) The traits would not obey the law of independent assortment because they are not inherited separately.
Answer:
C is the correct answer.
The traits would not obey the law of independent assortment because they are always inherited separately. Therefore, option (B) is correct.
What is The law of independent assortment?The law of independent assortment is a fundamental principle in genetics that describes how genes are inherited independently of each other during meiosis. This principle was first proposed by Gregor Mendel, who discovered the basic laws of inheritance in pea plants.
According to the law of independent assortment, the inheritance of one trait is not affected by the inheritance of another trait, as long as they are located on different chromosomes or are far apart on the same chromosome.
During meiosis, homologous chromosomes pair up and line up randomly at the metaphase plate, and the orientation of one pair of chromosomes is independent of the orientation of another pair. This results in the independent assortment of genes, which allows for the formation of new genetic combinations and contributes to genetic diversity.

When one part of the heart contracts, blood moves from the heart to the lungs. Which statement best explains this motion of the blood?
A. The heart only contracts when it contains blood with high oxygen content.
B. The lungs cause the heart to contract when they need more blood.
C. The lungs move to inhale and exhale gases when the heart contracts.
D. The heart supplies the force that moves blood through the body.
Answer:
I believe it's C
Explanation:
Answer:
D. The heart supplies the force that moves blood through the body
Explanation:
When a chamber of the heart contracts, the pressure provides a force that makes the blood move. Valves make sure that the force pushes the blood in the correct direction. Therefore, the statement which best explains this motion of the blood is that the heart supplies the force which moves blood through the body.
