Which pair of microscope views represents a eukaryotic cell and a prokaryotic cell?
Answer:
They can both be unicellular and multicellular
Explanation:
The difference between the two microscope views of an eukaryotic cell and a prokaryotic cell is that the eukaryotic cell appears to have a distinct nucleus and other organelles when viewed with a light microscope, whereas the prokaryotes do not.
What is the difference between eukaryotes and prokaryotes?Eukaryotic cells have a distinct nucleus and other membrane-bound organelles, while these are absent in the prokaryotic cells, and the prokaryotic cells are smaller in size than eukaryotic cells due to the lack of organelles.
Hence, the difference between the two microscope views of an eukaryotic cell and a prokaryotic cell is that the eukaryotic cell appears to have a distinct nucleus and other organelles when viewed with a light microscope, whereas the prokaryotes do not.

Which would be the best evidence that a cell is using active transport to move a substance across its cell membrane
Answer: The DNA located in the nucleus of the cell. ATP is being rapidly consumed near the cellular membrane.
Explanation:
At which stage is glucose broken into smaller molecules? O before cellular respiration begins Oduring the first stage of cellular respiration during the second stage of cellular respiration Oat the end of cellular respiration
Answer: The first stage of cellular respiration, called glycolysis, takes place in the cytoplasm.
Explanation:
In this step, enzymes split a molecule of glucose into two molecules of pyruvate, which releases energy that is transferred to ATP.
hope this helps!
During cellular respiration, the lysis of glucose is the first step for the oxidation of glucose, hence option B is correct.
What is cellular respiration?Cellular respiration is the process through which cells get energy in the presence of oxygen from organic molecules and release carbon dioxide as a by-product.
There are several steps for cellular respiration through which energy is extracted from the glucose, the first step glucose is breakdowns to convert into pyruvate and then this oxidizes through the citric acid cycle and produces electrons that generate ATP.
The breaking of glucose through glycolysis which is the first step of cellular respiration generates electrons that flow through the electron transport chain and generate ATP as the cellular energy product.
Therefore, glucose is broken into smaller molecules in the first stage of cellular respiration.

the information in DNA i. the nucleus is used to produce
A. proteins
B.Amino acids
C. Lipids
D. all the above
The nucleus's DNA contains information that is used to make proteins, so the correct option is a. proteins.
The genetic instructions that control the order of amino acids in proteins are found in DNA. Protein synthesis entails the transcription of DNA into messenger RNA (mRNA) and the subsequent translation of mRNA into a particular sequence of amino acids that constitute proteins.
Even though lipids are significant molecules involved in numerous physiological processes, DNA-based instructions do not directly govern how lipids are produced. Different cellular functions and enzymes control the synthesis of lipids.

4. How are ocean trenches formed? (1 point)
Ocean trenches are formed when oceanic plate cools and moves to the surface of the ocean.
Ocean trenches are formed when the denser oceanic late sinks.
Ocean trenches are formed when molten rock cools and solidifies.
Ocean trenches are formed when magma accumulates on the ocean floor.
Answer:
Ocean trenches are formed when the denser oceanic plates sink.
Explanation:
In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.

Atoms of which three elements could bond together to form an organic compound?
a. oxygen, iron, and carbon
b. carbon, hydrogen, and oxygen
c. oxygen, hydrogen, and nitrogen
d. carbon, iron, and nitrogen
Answer:
Hello!!! Princess Sakura here ^^
Explanation:
It's B because organic compounds are molecules that contain carbon atoms bonded to hydrogen atoms and choice B is the only one that has both.
The three elements carbon, hydrogen, and oxygen make up more than 99 percent of organic compounds. Carbohydrates, lipids, and proteins are only a few of the chemical compounds that these three combine to create nearly all the chemical structures required for life.
What are the main constituents of an organic compound?Any of a vast group of chemical compounds known as organic compounds contain one or more carbon atoms that are covalently connected to atoms of other elements,
most frequently hydrogen, oxygen, or nitrogen. Carbides, carbonates, and cyanides are among the few carbon-containing substances that aren't categorized as organic.
Organic substances are made of carbon, hydrogen, and frequently oxygen or nitrogen. Given that they are linked to living things, organic chemicals are given that term.
Carbohydrates, lipids, nucleic acids, and proteins are a few significant categories of organic molecules.

Which of the following is a MECHANICAL wave vibration? * O Sound waves O Light waves O Radio waves O Reflection
Answer:
An example of vibration by mechanical waves is sound waves.
Explanation:
Mechanical waves are those capable of transmitting energy, which can propagate in the same direction, resulting in an alteration of the mechanical properties of a material. As a result of this, the material presents changes in the energy of its atoms and molecules.
Sound waves are mechanical waves, which require a medium for transmission and act as elastic waves capable of propagating longitudinally, producing a vibration.
Sound propagates and can produce waves in water or vibrations that reach the eardrum and enable the reception of this sound.
The other options are not correct, because light and radio waves are electromagnetic waves that are transmitted in a vacuum, without producing vibrations. Reflection is a property of light.

How do waves interact with different materials?
Answer:
Waves interact with matter in several ways. The interactions occur when waves pass from one medium to another. Besides bouncing back like an echo, waves may bend or spread out when they strike a new medium. These three ways that waves may interact with matter are called reflection, refraction, and diffraction.
Explanation:
Waves interact with materials by eroding them over time. The way they the material erodes and how long it takes depends on the type of material. For example, less dense rock will break apart when it erodes, and it will not take as long. Metal will rust when it gets eroded, and it will take longer to be fully eroded.
