Trypanosomes are able to evade the host's immune system by altering the type of molecules expressed on their surface. This mechanism, known as antigenic variation, allows the parasites to persist within the host and cause disease.

Trypanosomes are a type of parasitic protozoa that can cause diseases such as sleeping sickness in humans and animals. One of the mechanisms that trypanosomes use to evade the host's immune system is by changing the type of molecules expressed on their surface. These molecules, known as variant surface glycoproteins (VSGs), act as a protective shield that allows the parasites to avoid detection by the host's immune cells.
The immune system of the host recognizes pathogens by identifying specific markers or antigens on their surface. In response, the host mounts an immune response to eliminate the invading pathogen. However, trypanosomes are able to alter the expression of VSGs on their surface through a process called antigenic variation. This allows the parasites to escape recognition by the immune system and survive within the host.
Trypanosomes have a large repertoire of VSG genes, which they switch between to produce different surface antigens. This process occurs through a complex genetic mechanism that involves gene conversion, deletion, and recombination. As a result, the parasites can continuously produce new VSGs, making it difficult for the host's immune system to keep up.

An S-wave would therefore need to travel the same distance from the epicenter to the seismic station in about 8.33 minutes.

S-waves move at a speed that is typically between 60% and 70% that of P-waves. For this computation, a cautious estimate of 60% is used.

We can calculate the time it would take for an S-wave to traverse the same distance if P-waves take five minutes to reach the seismic station by dividing the P-wave time by 0.6:

Time for S-wave equals Time for P-wave / 0.6, or 5 minutes divided by 0.6 results in 8.33 minutes.

Answer: More mutations

Explanation:

Protein-coding genes are responsible for encoding proteins that are essential for various biological processes within an organism. Mutations, or changes in the genetic sequence of these genes, can result in altered proteins that may lead to functional changes or impairments.

In some cases, a protein-coding gene may undergo mutations that render it non-functional, meaning it no longer plays a role in the biological processes of an organism. When this happens, the gene may continue to accumulate mutations without any selective pressure to maintain its function.

Therefore, a former protein-coding gene that is no longer functional may accumulate more mutations than a gene that encodes a protein that is functionally important.

The outer shell membrane in an animal cell represents the cell membrane.

The cell membrane, also called the plasma membrane,

The plasma membrane is a vital component that surrounds the cell, acting as a protective barrier and controlling the movement of substances into and out of the cell. It consists of a phospholipid bilayer embedded with various proteins that serve essential functions.

The phospholipid bilayer provides the foundation of the plasma membrane, with its hydrophilic heads facing the watery extracellular and intracellular environments, and the hydrophobic tails oriented towards the interior of the membrane. This structure creates a selectively permeable barrier that regulates the passage of molecules and ions.

The proteins embedded in the plasma membrane play diverse roles. Some proteins serve as transporters or channels, facilitating the movement of specific substances across the membrane.

Others act as receptors, allowing the cell to receive and respond to external signals. Additionally, there are proteins involved in cell adhesion, cell signaling, and enzymatic activities.

The plasma membrane is essential for maintaining the cell's internal environment and integrity. It regulates the exchange of nutrients, waste products, and signaling molecules, while preventing the loss of vital cellular components.

Moreover, the plasma membrane plays a crucial role in cell recognition and communication, enabling interactions with neighboring cells and the surrounding environment.

Overall, the outer shell membrane, or plasma membrane, is a dynamic structure that is fundamental to the proper functioning and survival of animal cells.

Answer:

Temperature and energy are closely related in science. Temperature is a measure of the average kinetic energy, or movement, of the particles in a substance. When the particles in an object have more kinetic energy, they move faster and collide more frequently.

As a result, the object's temperature increases. Conversely, when particles have less kinetic energy, they move slower and collide less often, causing the temperature to decrease.

Therefore, temperature can be considered as a way to measure the amount of energy present in a substance, where higher temperatures correspond to greater energy levels.

Answer:

Temperature is a measure of the average kinetic energy of the particles in a substance. Kinetic energy is the energy of motion, and it depends on the speed and mass of the particles. The faster the particles move, the more kinetic energy they have, and the higher the temperature of the substance. The relationship between temperature and energy is also affected by the specific heat capacity of the substance, which is the amount of energy needed to raise the temperature of one gram of the substance by one degree Celsius. Different substances have different specific heat capacities, depending on their molecular structure and interactions. For example, water has a high specific heat capacity, which means it takes a lot of energy to change its temperature, while metals have low specific heat capacities, which means they heat up and cool down quickly.

The question is not clear, so the clear question is as follows:

A cell has a 5 percent salt concentration. It is placed into a solution with a 0.5 percent salt concentration. What will happen to the cell?

Answer:

Cell will get swelled and burst

Explanation:

When a cell is placed in a solution with less concentration, then the solvent particles move from lower concentration to higher concentration through a semipermeable membrane and the process s called osmosis.

In this case also, the cell has higher concentration and the solution has less, so water will move into the animal cell, causing it to swell and burst after some time.

Hence, the correct asnwer is "Cell will get swelled and burst".

Answer:

Water will move into the cell, causing it to swell.

Explanation:

The cell has higher concentration of solute and a lower concentration of water than the solution it is placed in. This means that water will move into the cell, causing it to swell and ultimately burst.
