nthesized by the cell. Select which piece of data would indicate the incorporation of radiolabeled amino acids during protein synthesis?
A) Radioactivity levels would increase first at the nucleus, followed by the Golgi, and then the cell membrane.
B) Radioactivity levels would increase first at the nucleus, followed by the ribosomes, and then the secretory vesicles.
C) Radioactivity levels would increase first at the rough endoplasmic reticulum, followed by the Golgi, and then the secretory vesicles.
D) Radioactivity levels would increase first at the rough endoplasmic reticulum, followed by the nucleus, and then the secretory vesicles.

Answer:

C) Radioactivity levels would increase first at the rough endoplasmic reticulum, followed by the Golgi, and then the secretory vesicles.

Explanation:

Radioactivity levels would increase first at the rough endoplasmic reticulum, followed by the Golgi, and then the secretory vesicles. Ribosomes attached on the rough ER will manufacture the proteins. The radioactivity will be seen here first. The ER transports the proteins to the Golgi for packaging, sorting, and modification. This is where the radioactivity will be seen next. The Golgi sorts and packages proteins into secretory vesicles, which will travel to the membrane for export. This is where the radioactivity will be seen last.

Anton Leeuwenhoek Devised a primitive microscope to observe a sample of his tooth scrapings. How did this help contribute it to
4vir4ik [10]

Answer:

C- it help to show that some bacteria are just one cell.

Explanation:

Anton Leeuwenhoek was the first scientist who observed the presence of bacteria in his tooth scratch under the microscope made by himself. At that time there was no concept of bacteria and he named those small creatures as animalcules which were later termed as bacteria.

Leeuwenhoek during 1670s  sent the details of his experimentation on algae and bacteria to Royal Society of London.

It was due to his that primitive experiment that made the discovery of bacteria and make it known to other scientists. Therefore option C is the best option that demonstrates that bacteria are single celled organisms that are very minute. When we look at cell theory there is a postulate that shows that cell is the fundamental unit of function and structure  of all living organisms. So, the work of Anton Leeuwenhoek holds substantial importance in the formulation of cell theory.

Hope it helps!

Due to an unusually high concentration of particles inside of a cell, the membrane starts to expand and finally bursts. which pr
erastovalidia [21]

Out of the following given choices;

A. The cell is unable to get more water into the cell.

 

B. The cell is unable to build more protein molecules.

 

C. The cell is unable to produce water molecules inside the cell.

 

D. The cell is unable to maintain a stable internal environment.

<span>The answer is D. Due to high amounts of proteins in the cell, osmotically active proteins cause the internal environment of the cell to be hypertonic to the extracellular fluid. This causes excess water to enter the cell by osmosis and resulting in lysis.  </span>

Select the appropriate shape for the given volume formula. V = pi r squared h. V = four-thirds pi r cubed. V = l w h. V = one-th
devlian [24]

Explanation:

          Volume of a cylinder = \pi r² h

          Volume of a sphere = \frac{4}{3}  \pi r³

          Volume of cone =  \frac{1}{3} \pi r² h

          Volume of cuboid = l w h

Where:

     r is the radius of the body measured

     h is the height

     l is the length

    w is the width

     

The volume of a body is the space it occupies and it refers to its size.

it is measured in cubic meters or cubic centimeters.

What can you infer about a species that has a random pattern of distribution over space? A uniform pattern?
Leona [35]

The individual organisms that frame a population are additional or less equally spaced, spread every which way with no predictable pattern, or clustered in teams. These are called the uniform, random, and clumped dispersion patterns.   Uniform refers to the evenly distributed population, random means random spacing and clumped shows the distribution in clusters.

Food supply and resources are directly proportional to a particular distribution pattern. Random distribution occurs when several pollen grains of some flowers were carried by wind or bees. These flowers will then bloom where they were scattered.

hope this um ... helps hehe ........
