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.

Young rivers-Carry large objects
Mature rivers-Carry medium-sized objects
The following are the correct matches:
Old rivers-Have many meandersYoung rivers-Carry large objectsMature rivers-Carry medium-sized objectsWhat are rivers?Rivers are bodies of flowing water that are typically found on the surface of the Earth. They are formed by the accumulation of precipitation, such as rain or snow, in a specific area and flow in a defined channel towards an ocean, a lake, or another river. Rivers can vary greatly in size and length, with some being just a few meters wide and a few kilometers long, while others can be several kilometers wide and thousands of kilometers long.
They are an important resource for humans and other living organisms, providing water for irrigation, drinking, and industrial uses, as well as serving as habitats for a wide variety of plant and animal life. Rivers also shape the land they flow through, eroding and depositing sediment, and creating features such as valleys, deltas and canyons.

Which is more important: species richness or species evenness?
Answer:
Honestly i think that its Richness because its good to have a good amount of different species so that there is a good number of animals to create a food chain. The amount of animals in a population is important but its more important to have a variety of different animals so that all the populations have other animals to eat or survive off of.

how can you use the electron configuration to determine the number of valence electrons
Here, we are required to explain how the electronic configuration can be used to determine the number of Valence electrons.
The algebraic sum of electrons in the highest energy level in an electron configuration is the number of Valence electrons of the element.Valence electrons simply refers to electrons present in the outermost shell of an element.
Valence electrons simply refers to electrons present in the outermost shell of an element.The electron configuration is a representation of the arrangement of electrons in the atomic orbitals of an element.
The number of electrons present in the outermost shell as evident from the electron configuration can be used to determine the Valence electron in the elements.Fir instance: the electron configuration of potassium; 1s² 2s² 2p⁶ 3s² 3p⁵
The algebraic sum of electrons in the energy level 3 therefore is the number of Valence electrons.

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.

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.

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.
