Answer:

The kind of changes with respect to the genetic traits that have occurred over several generations in an agriculture crop should be environment, generation, etc.

Environment deals with the external conditions and factors, that should be lived or non-lived also it impact an organism at the life time period.

While on the other hand, the generation should be the step with respect to the line of the family descent

Therefore, in this way, the changes should be considered.

Answer:

isotonic: in equilibrium.

Explanation:

tonicity is the relative concentration of solutes dissolved in solution which determine the direction and extent of diffusion. if let's say sodium is the same both inside the cell membrane and outside the cell membrane then it is isotonic in equilibrium.

Explanation:

Meiosis produces 4 haploid cells -gametes- from a single diploid cell. The statement that is not true is 4).  the observations suggest cellular reproduction and general growth and repair of the body.

According to this information, we can assume that the students are observing the occurrence of meiosis events.

Through Meiosis, a diploid cell (2n) produces four haploid daughter cells (n). Thes haploid cells are the gametes.

After DNA replication there are two meiotic phases.

1. In the first phase, Meiosis I:

2. In the second phase, Meiosis II:

1.) the slides were of an egg cell or sperm cell ⇒ Correct. It makes reference to gametes -haploid cells-.

2.) the process observed produce genetically different cells ⇒ Correct. After crossing over and independent segregation of chromosomes.

3.) the number of chromosomes resulting from the process is reduced by half ⇒ Correct. After the reductive phase.

4.) the observations suggest cellular reproduction and general growth and repair of the body. ⇒ INCORRECT. Mitosis is in charge of general growth and repair of the body, not meiosis.

Explanation:

Microfilaments are a component of the cell's cytoskeleton and these are made up of the actin protein. They are involved in the cellular movement. Thus, the correct option is B.

Microfilaments are also called as actin filaments, as they consist of two intertwined strands of a globular protein, which is known as actin protein. In association with myosin, microfilaments help to generate forces that are used in cellular contraction and cellular movements. During cell division, these filaments results into dividing cell to pinch off into two daughter cells and are involved in amoeboid movements of certain types of cells.

Microfilaments assist with cellular movement due to the presence of actin filaments. Actin filament works with another protein called myosin to produce muscular movements, cell division, and cytoplasmic streaming during cell division. Microfilaments keep the organelles in place within the cell.

Therefore, the correct option is B.

The personal items should be off the table, and the lab materials should be placed neatly away from the edge of the table.

Explanation:

It is given that Maribel goes to the lab with her backpack and she is given the lab materials to be used inside the lab to perform her experiment.

Now Maribel in the lab before doing her experiment must keep the personal items like her backpack off the working table and the lab materials are should be kept away from the edge of the table otherwise it might fall accidentally and hurt her.

One needs to be very careful while in the laboratory. One should follow the safety procedures to remain safe and also ensure safety of others. Being unsafe and disorganize can hurt others and can cause harm to others. There are various equipment and chemical in the lab. Therefore one should be careful while working in the lab.

Explanation:

Jimmy was right to say organisms grow because their cells grow.

The growth of organisms can happen in terms of an increase in the number of cells they have (through mitotic cell division) or an increase in the volume of the cells with or without an increase in the number of cells.

A good example is found in plants, most of which undergo an increase in size without any increase in the number of cells in their bodies. The uptake and storage of water in the vacuole produces a pressure that pushes on the cell walls, causing an increase in length, girths, and other growth features of the cells of plants.

Answer:

Answer:

Once assembled, what is the key to a protein's unique function? The manner in which proteins fold is the key to their function

The endoplasmic reticulum is an important  region where protein folding occur. Because proteins need to be appropriately folded into distinct structures, this is an essential biological function.

Proteins that are misfolded or are unfolded improperly impart to the pathophysiology of many illnesses.

Protein folding is a highly delicate process that is regulated by a variety of external stimuli, such as temperature, pH, chemicals, molecule crowding, electric and magnetic fields, and temperature.

These elements affect a protein's capacity to fold into the appropriate functional forms.

Therefore, Protein folding give unique properties to protein functions.
