The diagram shows a typical plant cell and its part. Which choice below identifies structures that are only found in plant cells (and NOT in animal cells)?

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.

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.

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.

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.

Answer:

Cells have proteins called receptors that bind to signaling molecules and initiate a physiological response. Different receptors are specific for different molecules. ... This is important because most signaling molecules are either too big or too charged to cross a cell's plasma membrane

Explanation:

hope this helps you have a good day

Receptors are transmembrane proteins, that bind to signaling molecules outside the cell and later transmit the signal through a sequence of molecular switches to internal signaling pathways.

Membrane receptors fall into three major classes namely G-protein-coupled receptors, ion channel receptors, and enzyme-linked receptors.

Not all receptors exist on the exterior of the cell. Some exist deep inside the cell, or even in the nucleus. These receptors typically bind to molecules which can pass through the plasma membrane, such as gases like nitrous oxide and steroid hormones like estrogen.

Answer:

photosynthesis

Explanation:

Plants and photosynthetic algae and bacteria use energy from sunlight to combine carbon dioxide (C02) from the atmosphere with water (H2O) to form carbohydrates. Oxygen (O2) is a byproduct that is released into the atmosphere.

Photosynthesis does not add carbon to atmosphere.

The process by which light energy is transformed into chemical energy in the form of sugars is known as photosynthesis. Using light energy, glucose (or other sugars) are created from carbon dioxide and water, with oxygen being released as a byproduct.

The glucose molecules act as the fuel for the cells; their chemical energy can be obtained through procedures like cellular respiration and fermentation, which result in the production of adenosine triphosphate (ATP), a small energy-carrying molecule, to meet the immediate energy requirements of the cell.

It is possible for organic molecules to integrate inorganic carbon from carbon dioxide; this process is known as carbon fixation, and the carbon in organic molecules is also known as photosynthesis.

Therefore, Photosynthesis does not add carbon to atmosphere.

Answer:

C) structural adaption

Explanation:

Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear. Other adaptations are behavioral. Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations. Adaptations are the result of evolution.

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.

When a molecule is biologically molecule synthesized, there will be a monomer unit converted into the polymer, so there is a change in molecule randomness so entropy is decreased, hence option b is correct.

When a biological molecule is synthesized the monomeric unit is converted into the polymeric unit and there will be a synthesis of bonds.

In a biological system, the system moves towards the spontaneous system, and the change in entropy should be increased. The biological system works only when it is a thermodynamically active system.

All the chemical reactions are held to move towards the equilibrium state when a biological molecule is synthesized change in the entropy of the system is decreased but a change in the entropy of the surroundings increases.

Therefore during the synthesis of biological molecules, entropy is decreased, hence option b is correct.

(Hope this helps)

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.

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.
