The nucleus includes all of the following structures EXCEPT
a
cytoplasm.
b
a nuclear envelope.
c
DNA.
d
a nucleolus.
Answers
Answer:
A. Cytoplasm
Explanation:
Cytoplasm is outside of the organelles, and is the jelly-like substance that holds all of the organelles and cell parts in place.
So, cytoplasm is not within the nucleus, because it is outside of the organelles, such as the nucleus.
On the other hand, the nuclear envelope, DNA, and nucleolus are all in the nucleus.
The nucleus includes all of the following structures except cytoplasm.
Thus, Cytoplasm is the name for the liquid that makes up cells. It includes additional organelles suspended in the cytosol along with filaments, ions, proteins, and macromolecular structures.
However, recent findings imply that the conventional notion of cytoplasm is no longer accurate. It was thought to be a fluid-like substance decades ago, but current research shows that it is more like liquids that create glass.
With the exception of the nucleus, the cytoplasm of eukaryotic cells is associated with the contents of the cell. Prokaryotic cells, however, lack a distinct nuclear membrane and instead store their genetic material in their cytoplasm.
Thus, The nucleus includes all of the following structures except cytoplasm.

Answers
Proteins
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.

How does a cold day affect enzyme activity during photosynthesis?
Answers
Answer:
At low temperatures, between 32 and 50 degrees Fahrenheit – 0 and 10 degrees Celsius – the enzymes that carry outphotosynthesis do not work efficiently, and this decreases the photosynthetic rate. This leads to a decrease in glucose production and will result in stunted growth.

How do waves interact with different materials?
Answers
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.
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
Answers
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.

Which statement about ionic bonds is correct? A. Ionic bonds form when similarly charged ions are attracted to each other B. Ionic bonds form when electrons are shared C. Ionic bonds form when oppositely charged ions are attracted to each other D. Ionic bonds form when a protons are shared between atoms.
Answers
Answer:
Option C. Ionic bonds form when oppositely charged ions are attracted to each other
Explanation:
An ionic bond is a bond that forms when two oppositely charged ions are electrostatically attracted to one other, where metal is an anion and nonmetal is a cation.
For instance, the bond between NaCl is an ionic bond where sodium is metal and anion (Na⁺) and chlorine is nonmetal and cation (Cl⁻) and makes salt.
Thus, the correct answer is - option C.

They should discuss differences in their methods.
They should record their results and move on to a different investigation
They should repeat the experiment using different pennies.
Answers
Answer:
B). They should discuss differences in their method.
Explanation:
As per the question, the next step in the given process would be 'the discussion of differences that exist between their methods which they are using to fill the cup.' This would help them understand how the difference in methods of putting water into the cup directly affects the tendency of the liquid to contract into the least surface area. They would also get to know how temperature affects the increase or decrease of surface tension. Thus, option B is the correct answer.

Ос
Od
chemosynthesis
nitrogen fixation
photosynthesis
cellular respiration
Answers
Answer:
The biological process that has led to the greatest transformation of life on Earth is chemosynthesis.
Explanation:
Chemosynthesis is a process that allows the production of inorganic molecules in organic matter, through the oxidation of molecules such as carbon dioxide (CO₂). A clear example of this is the photosynthesis carried out by plants, taking advantage of CO₂ to generate their nutrients.
It is proposed that chemosynthesis was responsible for generating organic matter from inorganic molecules that existed on earth before the origin of life. It was perhaps the first metabolic reaction that arose on earth. Photosynthesis and cellular respiration are processes that follow chemosynthesis.
The other options are not correct, because cellular respiration, biological nitrogen fixation and photosynthesis appeared on earth after the origin of living organisms.
