In an experiment investigating the mechanism of protein secretion, researchers
tracked the movement of radioactively labeled polypeptides in pancreatic cells. At
various times after the labeling, samples of the cells were observed using an electron
microscope to determine the location of the radioactively labeled polypeptides.
Figure 1 summarizes the results at 5 minutes, 15 minutes, and 30 minutes. The dark
dots in the figure represent the radioactively labeled polypeptides.

Answer:

Core organelles are found in virtually all eukaryotic cells. They carry out essential functions that are necessary for the survival of cells – harvesting energy, making new proteins, getting rid of waste and so on.

Answer:

Organelles are also called vesicles within a cell. And they really have a function that's important, because we need to compartmentalize all the functions within the cell. So there needs to be a membrane around the mechanisms for making a different product within a cell. So really, organelles are all membrane-bound.

Answer:

Because males are never carriers for x-linked trait, only females are carriers which gives them a lower chance of receiving the trait. While males can either have the trait or not have it.

Answer:

C) earthquakes and volcanoes are most common along tectonic plate boundaries.

Tectonic plate boundaries are the areas where the Earth's tectonic plates meet and interact. There are three types of plate boundaries: divergent, where plates move apart and magma rises to create new oceanic crust; convergent, where plates collide and one is either pushed beneath the other, creating a subduction zone, or both are deformed, forming mountain ranges; and transform, where plates slide past each other, resulting in earthquakes.

Understanding plate boundaries is crucial to understanding earthquakes, volcanic activity, and mountain building processes.

Answer:

Alveoli would have lower levels of carbon dioxide and the blood would have higher carbon dioxide levels.

Explanation:

This is because carbon dioxide follows the lower concentration gradient causing lower levels in Alveoli and higher in the blood.

Carbon dioxide gas leave the blood and enters the alveoli when the concentration of carbon dioxide in the alveoli is lower as compared to concentration in the blood.

Diffusion is the process of transport of gases in cell. This process includes the transport of gases from region of their higher concentration to the region of their lower concentration. This process is energy independent. The transport does not require any transport protein- carrier or channel.

The diffusion of gases in the cell and blood takes place from higher concentration to lower concentration. The carbon dioxide gas has higher concentration in the blood as compared to the alveoli that's why it moves from blood to the alveoli where the concentration of the gas is comparatively low.

Answer:

A. The taiga biome has four distinct seasons. Is the answer.

Explanation:

I just took the test.

Answer:

a. The taiga biome has four distinct seasons.

Earth's circumference is about 40,000 km, and its shape is an oblate spheroid.

Earth's shape is an oblate spheroid, this defines that it flattens at the poles and widens out at the equator.

It has an oblate spheroid form, simply said, it narrows near the equator and widens at the poles. The Earth's equator bulges as a result of the rotation's centrifugal force. The mass flattens out and pushes outward along the axis of rotation, like spinning a pizza.

An ellipse is rotated about its minor axis to create an oblate spheroid, which is a surface of revolution (Hilbert and Cohn-Vossen 1999). A rotating fluid, such as the Earth, which is "fluid" over astronomical time periods, typically assumes the shape of an oblate spheroid.

Therefore, an oblate spheroid is correct.

Answer: the SRY gene produces a protein that binds to specific regions of DNA in certain tissues, which affects the development of these tissues

Explanation: i got it right on my quiz

The SRY gene is the sex determining region of the Y chromosomes. The correct information about the cell signalling of SRY gene is:

The SRY gene is also known as the Testes-Determining Factor, which initiates the cascades of process vital to form testes. The SRY gene is found in Y-chromosomes. The Y protein produced acts as a transcription factor, which binds to the specific regions of DNA. The genes helps in controlling the activity of particular genes and help in formation of gonads from undifferentiated tissues. The SRY gene is present on the Y-chromosome, which determines the male characteristics during the fetal development.

Therefore, the SRY genes initiates the cascade of processes to form testes. The gene secrete a protein that binds to specific sequence in the DNA.

DNA

Explanation:

RNA is not a double helix

Uracil is on the RNA, this is a picture or DNA. Uracil is just one of the nucleic bases

This is not a monomer; it's actually a polymer

It is DNA because it is a double helix structure held together by the four nucleic bases.

The illustration below represents the double helical structure of DNA. Thus, the correct option for this question is D.

DNA stands for deoxyribonucleic acid. It may be defined as a type of molecule that contains the genetic information responsible for the development and function of an organism. It is present in the nucleus of the cell. DNA is the most common type of genetic material among living organisms.

The illustration below is not RNA because RNA is only made up of single-stranded. While uracil is a type of base which is particularly present in the RNA instead of thymine.

DNA is the polymer of building units or monomers of nucleotides which are generally present in the structure with the help of covalent and hydrogen bonding. There are various types of bases present over the nucleotide which defines the arrangement of DNA molecules.

Therefore, the illustration below represents the double helical structure of DNA. Thus, the correct option for this question is D.

Explanation:

Answer:

When the organism inherits a mutated gene creating new colored organisms into the population, this can increase diversity. As more organisms inherit the same mutation, the population will become more variated, which can increase the organisms abilities to survive and adapt in a changing environment, and also improve the biological fitness of individuals; resulting in allowing more organisms to reproduce successfully.

Answer:

Although the thymus is shrinking with age, it is still functional in adults, thereby this statement is incorrect  

Explanation:

The thymus is a specialized primary lymphoid organ that has a key role in the production and maturation of T cells (i.e., thymus-derived cells). The thymus grows until puberty, but during adulthood, this vital organ starts to shrink, a process known as 'thymic involution'. During all life, the thymus plays roles in immunity and autoimmunity. The thymus produces progenitor cells that mature into T-cells, which are one of the main components of the adaptive immune system. These cells function by killing infected/sick cells (for example, cancer cells), by activating other immune cells, by synthesizing signaling molecules (i.e., cytokines), etc.
