Explanation:
The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA.
Mitochondria play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.
Ribosomes are small cellular structures and are the site of protein synthesis. Ribosomes are found in all cells.
Chromosomes are very important because they contain vast majority of genetic information of organism. The organism's DNA is contained within the chromosome as a long series of nucleotides thar are organised into genes. And helps to inherit the characters of parents to their offsprings.
The nucleus is the control center of the cell. Chromosomes are structures in the nucleus that contain DNA. Mitochondria are organelles that are often called the "powerhouses" of the cell. Ribosomes are organelles that are responsible for protein synthesis.
Nucleus: It contains the cell's DNA, which is the genetic material that determines the cell's structure and function. The nucleus also contains proteins that are involved in gene expression, which is the process by which DNA is decoded to produce proteins.
Chromosomes: There are 23 pairs of chromosomes in human cells, for a total of 46 chromosomes. The chromosomes are made up of DNA and proteins, and they are responsible for storing and transmitting genetic information.
Mitochondria: They are responsible for producing ATP, which is the cell's main source of energy. Mitochondria are surrounded by a double membrane, and the space between the membranes is filled with a fluid called the mitochondrial matrix. The mitochondrial matrix contains enzymes that are involved in the production of ATP.
Ribosomes: They are made up of two subunits, and they are located in the cytoplasm of the cell. Ribosomes can also be found attached to the endoplasmic reticulum. Proteins that are synthesized by ribosomes are used by the cell for a variety of purposes, including structure, metabolism, and transport.

unique characteristic feature of a virus ?
Answer:
They are acellular, that is, they contain no cytoplasm or cellular organelles. They carry out no metabolism on their own and must replicate using the host cell's metabolic machinery. In other words, viruses don't grow and divide. Instead, new viral components are synthesized and assembled within the infected host cell.

Answer: b
Explanation:
Why do organisms have varying traits, like different colored eggs?
What might drive change in egg color in natural population?
Is this experiment an example of natural or artificial selection and why?
the organisms have varying traits, like different colored eggs because of the natural selection.
What is the process of natural selection?Natural selection is one of the main mechanisms of evolution. In a very simple way, we can say that natural selection is a process in which the fittest organisms are selected, survive in the environment, reproduce and pass their characteristics on to their descendants.
the color change of an egg occurs by natural selection and also by genetic variability. since the environment will select the best ones to survive and mutations will occur. Natural selection will forcefully change the environment causing only a few species to survive.

Summarize the four major types of biochemical reactions studied in this course. For each type give the name, a word summary of what happens during the reaction, and an example of where the reaction might be biologically important.
Oxidation-Reduction (Redox):
When electrons are moved from one element to another, the process is known as a redox (or oxidation-reduction) reaction. In most cases, one element loses electrons while another gains them. It is said that the factor influencing elections has decreased. Oxidation occurs to an element that loses electrons. Although it can seem counterintuitive, adding electrons is really a lowering of the element's oxidation state, or charge. For instance, when an oxygen atom is oxidized, its charge changes from -2 to 0 (neutral). As electrons are taken away, the charge would alter. For a decrease, the reverse occurs. Biological Importance of Alcohol Oxidation to Aldehydes or Ketones. An essential stage in the breakdown of lipids during human metabolism is the conversion of alcohol groups to carbonyl groups (e.g. L- malate to oxaloacetate). The citric acid cycle also includes these oxidations. The liver converts ethanol to acetaldehyde, which is next converted to acetic acid, a natural component of cells, and finally to carbon dioxide and water. However, ethanol may be hazardous to people. Most individuals would die after ingesting 1 pt (or 500 mL) of pure ethanol quickly, and acute ethanol poisoning claims the lives of several hundred people annually, frequently those participating in drinking competitions. Alcohol easily enters the brain, where it suppresses the respiratory control center, impairing the breathing muscles in the lungs and ultimately leading to asphyxia. According to theory, ethanol damages nerve cell membranes, impairing speech, thinking, cognition, and judgment. Isopropyl alcohol is often dissolved in water at a 70% concentration for rubbing alcohol. It quickly evaporates off the skin and has a high vapor pressure, which provides a cooling effect. Although it is hazardous when consumed, methanol is more easily absorbed via the skin.
Hydrolysis:
In a chemical reaction known as hydrolysis, which is the reverse of condensation, water breaks down another substance and modifies its chemical structure. While inorganic hydrolysis connects water with ionic molecules like acids, salts, and bases, most occurrences of organic hydrolysis combine water with neutral molecules. The interaction of water with an ester of a carboxylic acid may serve as an illustration of the hydrolysis of organic molecules. When esters and the majority of other organic compounds are hydrolyzed, a third substance—typically an acid or a base—increases the rate at which the chemical transformation occurs. One instance of hydrolysis is food digesting. The substances you've consumed are broken down by the water. This makes it possible for the bigger compounds to be broken down into smaller ones so they may be absorbed more readily.
Condensation:
A condensation reaction is a type of organic addition reaction that produces both a water molecule and the addition product, often in equilibrium. Otherwise, acetic acid, ethanol, or ammonia may be produced by the process. An example of condensation reaction would be Morning Dew on the Grass. The air close to the ground cools to or below the dew point overnight. As a result, the atmosphere's water vapor becomes saturated and begins to condense, forming dew on the grass.
Neutralization:
The term "neutralization reaction" describes the processes that happen when basic and acidic compounds interact and counteract each other's effects to produce salt, water, and energy (heat). An example would be a neutralizing antibody. It refers to an antibody's capacity to block the site(s) on bacteria or viruses that they employ to enter their target cell in an immunological sense. A neutralizing antibody is one biological illustration of this.

The paper airplane will move in a straight line, according to Newton’s first law of motion.
The paper airplane will drop straight to the ground once its inertia gives in to the force of gravity.
The paper airplane will create a curved path toward the floor as it is pulled toward Earth’s center.
The paper airplane will orbit around the desk because it is the object with the largest mass in the room.
Answer:

The paper airplane will create a curved path toward the floor as it is pulled toward Earth’s center. Therefore, option (C) is correct.
Gravity draws items towards Earth's centre. Gravity will speed the paper aeroplane when released. Thus, the paper aeroplane will curve towards the floor, increasing speed until it hits the ground.
As it falls, gravity accelerates the paper aeroplane towards Earth, causing its curved course. Since the paper aeroplane is not at rest or in uniform motion, Newton's first law of motion—the law of inertia—does not apply. Therefore, option (C) is correct.
