Why do scientist study ice cores
Select all that apply
To study Earth's past climates
To study how Earth's climate is changing now
To study how climate typically stays the same
To study how it might change in the future
Answer:
to study earth's past climate
Answer:
Explanation:
Air bubbles and dust get trapped in ice as it forms. And the ice in some places, like Antarctica, has stayed frozen for over a million years. Scientists drill holes in the ice and remove ice cores. Each year's worth of ice forms a layer within the core.
The material trapped in ice layers gives information about the climate at that time. Scientists study the layers to learn about past temperatures and precipitation. They can learn how the amount of carbon dioxide in the atmosphere has changed over time. The layers also reveal when events such as volcanic eruptions have taken place.

(DNA) located?
A. Lysosomes
B. Nucleus
C. Ribosomes
D. Vacuole
Answer:
DNA is found in the nucleus. So B.
Explanation:
DNA is found in chromosomes and chromosomes are found in the nucleus because the nucleus is basically the DNA of a cell.
In the nucleus, cell structures are the Drosophila chromosomes (DNA) located. The correct option is B.
What is chromosomes?The thread-like components known as chromosomes are found in the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA).
DNA is passed down from parents to children and contains the precise instructions that give each kind of living thing its individuality.
a component that can be found in a cell's nucleus. Proteins and DNA are arranged into genes on a chromosome. There are typically 23 pairs of chromosomes in each cell.
One chromosome is made up of one protein and one DNA molecule. Different chromosome sizes can be packed together into a nucleus thanks to proteins called histones.
The DNA for the Drosophila chromosomes is found in the cell's nucleus.
Thus, the correct option is B.

Monomers are the building blocks of larger molecules called polymers. A polymer consists of repeating monomers bonded to each other with covalent bonds.
Use the draw pad to connect each monomer to its polymer.
Answer:
Explanation: It connects to each one shown below. All correct.
The monomer of DNA is a nucleotide. The monomer of glucose is carbon, hydrogen, and oxygen.
What are monomers and polymers?The simplest form of polymers is monomers. To create polymers, each monomer is combined. Usually, a double bond or triple bond holds the monomer together.
Typically, monomers contain two free electrons that pair together and create a double bond among themselves. The monomers of cellulose are an example of a monomer and contain glucose.
A monomer is a molecule that, when combined with additional monomers of the same kind, can create a polymer, such as glucose (C6H12O6). A biological polymer made of several -glucose units is cellulose, which serves as an illustration of this.
Therefore, the monomer of DNA is a nucleotide. The monomer of glucose is carbon, hydrogen, and oxygen. The monomer of their polymers is matched in the added picture.

A shadow is caused when an object blocks sunlight. For example, when your body blocks sunlight, you may see a shadow of yourself on the ground. How do you think the shadow of an object, such as a flagpole, would change over the course of the day as the Sun appears to move across the sky?
Answer:
The position of the sun affects the change in the direction and size of the shadow of the object. When sunlight is blocked by and object a shadow forms, as the earth moves on its axis daily it looks like the sun rises in the east and sets on the west.
When the sun is low in the sky the more light is blocked by an object which means the shadow will be longer and shadow will always point far from the direction of the sun.
In the morning sun is in the east so the shadow will be towards the west in the morning, shadows are long and point northwest and at noon, shadows are short and point north late afternoon shadows are long and towards the northeast.

The function of the nucleolus includes 'beginning ribosome assembly'.
The nucleoli are eukaryotic organelles located within the cell nucleus that act as ribosome factories, in which the process of transcription (i.e., RNA synthesis) occurs constantly.
The nucleolus serves to make ribosomal subunits and then it sends ribosomal subunits to different cell destinations where they form full ribosomes.

Most S-waves from an earthquake disappear at a distance of about 11,500 kilometers from the epicenter of the earthquake. Explain why this occurs in terms of structure of Earth's interion.
Answer:
When an earthquake occurs the seismic waves (P and S waves) spread out in all directions through the Earth's interior. Seismic stations located at increasing distances from the earthquake epicenter will record seismic waves that have traveled through increasing depths in the Earth.
Seismic velocities depend on the material properties such as composition, mineral phase and packing structure, temperature, and pressure of the media through which seismic waves pass. Seismic waves travel more quickly through denser materials and therefore generally travel more quickly with depth. Anomalously hot areas slow down seismic waves. Seismic waves move more slowly through a liquid than a solid. Molten areas within the Earth slow down P waves and stop S waves because their shearing motion cannot be transmitted through a liquid. Partially molten areas may slow down the P waves and attenuate or weaken S waves.
When seismic waves pass between geologic layers with contrasting seismic velocities (when any wave passes through media with distinctly differing velocities) reflections, refraction (bending), and the production of new wave phases (e.g., an S wave produced from a P wave) often result. Sudden jumps in seismic velocities across a boundary are known as seismic discontinuities.
Within the Earth, molten areas slow down P-waves and stop S-waves because shearing motion of the waves cannot be transmitted through a liquid.
Earthquake cause the seismic waves (P and S waves) that spread out in all directions even in the Earth's interior. Seismic waves move more slowly through a liquid than a solid.
Within the Earth, molten areas slow down P-waves and stop S-waves because shearing motion of the waves cannot be transmitted through a liquid.
Therefore, most of the S-waves of an earthquake disappear about a distance of 11,500 km from the epicenter.

Suppose a scientist measures the amount of DNA per cell of a particular diploid species at various stages of meiosis. She finds that the meiotic cells contain 3.7 pg, 7.3 pg, or 14.6 pg of DNA. Match each stage of the cell cycle to the corresponding amount of DNA contained within a cell at that stage.
1. metaphase II2. prophase I3. G14. after cytokinasis of meiosis II5. telophase I before cytokinesis6. G2
Answer:
1. metaphase II - 7.3 pg.
2. prophase I - 14.6 pg.
3. G1 - 7.3 pg.
4. after cytokinesis of meiosis II - 3.7 pg.
5. telophase I before cytokinesis - 14.6 pg.
6. G2 - 14.6 pg.
Explanation:
The cell cycle begins at G1, where all cells in humans (except for the gametes) have 23 pairs of chromosomes, 46 in total, and without any part of the DNA being duplicated. This is the stage in which the cell will have 7.3 pg of DNA.
After G1 comes phase S, which is the phase in which the DNA is duplicated to prepare the cell for the oncoming division; so we can infer that the phase that comes after S, G2, will have twice the DNA the cell had initially: 14.6 pg.
With this amount of DNA, the cell enters the first part of meiosis, in which the homologous chromosomes will be separated into two cells that will each carry on with the second part of meiosis. In prophase I, the cell is just beginning the process of meiosis, so it has 14.6 pg of DNA. In telophase I, the cell still has that amount of DNA because cytokinesis hasn't happened yet, and that is the defining step that ends up actually dividing the cell into two.
Meiosis II begins after cytokinesis I, therefore, the homologous chromosomes have already been separated and each cell has now 7.3 pg. In metaphase II the cell has 7.3 pg, but when cytokinesis of meiosis II ends, the cell will be half the size that was just before, because the sister chromatids are separated - this is where the cell will only have 3.7 pg of DNA.
The cells produced by meiotic cells are gametes, having only 23 chromosomes and the lowest amount possible of DNA.
What is meant by "true nucleus".
it simply means the cell's DNA is surrounded by a membrane. therefore the nucleus houses the cell's DNA and directs the synthesis of the proteins and ribosomes the cellular responsible for protein synthesis.
