Answer:

DNA “typos” cause variation

Explanation:

Any time DNA is copied, a mistake or change can occur in the letters of the DNA sequence, or gene. These changes result in variations or differences in DNA from person to person.

The "typos" that happen when DNA is being copied is mutations and variations.

A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.

Moreover, mutations result either from errors in DNA replication or from the damaging effects of mutagens, such as chemicals and radiation, which react with DNA and change the structures of individual nucleotides.

Therefore, mutations within the DNA are a fairly common event. Mutations are random changes that occur within the sequence of bases in DNA. They can be large scale, altering the structure of the chromosomes.

Potential energy is greatest at point D. Therefore, option C is correct.

Potential energy is the energy that is stored inside of an object due to the object's position, state, or arrangement. When an object's position, status, or configuration changes, the energy that has been stored in it is released.

The gravitational potential energy of an item, the elastic potential energy of a stretched spring, and the electric potential energy of an electric charge in an electric field are examples of common types of potential energy.

Potential energy depends upon the mass and height of the object. The greater the mass and height, the greater will be the potential energy of the object. The height of position D is maximum, therefore potential energy is greatest at point D. Hence, option C is correct.

Explanation:

Answer:

Recticuli(rectangular)

"Recticuli (rectangular)" is not among the most common cell shapes found in prokaryotes. Therefore, option (D) is correct.

Rectangular cells, represented by "Recticuli" in your options, are not among the most common cell shapes found in prokaryotes. Prokaryotes are primarily characterized by cocci (spherical), bacilli (rod-shaped), and spirochetes (spiral-shaped) forms. Cocci are typically round, bacilli are elongated rods, and spirochetes exhibit a spiral or helical structure.

These shapes facilitate various functions such as movement, attachment, and replication. Rectangular cells, while theoretically possible, are not commonly observed in natural prokaryotic populations. The lack of real-world prevalence could be attributed to the structural challenges and limited advantages of such a shape in prokaryotic environments. The prevailing shapes have likely evolved due to their practical benefits, underscoring the connection between form and function in these microorganisms. Therefore, option (D) is correct.

Explanation:

Lysosome organelle is most likely malfunctioning in the patient's cells (option b),.

The organelle most likely malfunctioning in the patient's cells is the lysosome. Lysosomes are membrane-bound organelles that contain enzymes responsible for breaking down waste materials, cellular debris, and foreign substances. They play a vital role in cellular waste disposal and recycling.

In this case, the patient is diagnosed with a disease caused by the buildup of waste material in the body's cells. This suggests that there is a problem with the breakdown and disposal of waste materials within the cells.

The Golgi apparatus is responsible for modifying, sorting, and packaging proteins for transport within or outside the cell. It is not directly involved in waste material breakdown.

Ribosomes are responsible for protein synthesis and are not directly involved in waste material breakdown either.

The endoplasmic reticulum (ER) is involved in protein synthesis, lipid metabolism, and detoxification. However, its dysfunction would not directly result in the buildup of waste material in the cells.

Therefore, considering the role of lysosomes in waste material breakdown, it is most likely that the malfunctioning organelle in the patient's cells is the lysosome. This malfunction would lead to the accumulation of waste material, causing the disease symptoms.

There are many different kinds of microscopes. A magnifying glass is a simple microscope. The term microscope commonly refers to a compound microscope. These Microsoft are called compound because they are made of several glass lenses in a tube. The total magnifying power of a microscope is the product of the magnifying power of the lens is in the ips and the magnifying power of the lens in the objective.. Most compound microscopes can magnify a specimen up to 400 times as real size. Microscope allow you to see fine details. Space is between objects that are closer together than 0.1 mm can be seen. The ability of a microscope to separate small distances is called resolving power. If the resolving power is not good the image will be blurred. When you look into the eye piece of microscope the circular area you see is the field of view when a ruler is placed across the opening of the stage the field of view can be measured in millimeters. Sharpening an image under high magnification used the Find adjustment knobs. The part of the microscope that holds the Microscope slide is called the stage.
