For two populations to be considered the same species, option B is correct: the two populations must descend from the same ancestors.In biological terms, a species is defined as a group of organisms that can interbreed and produce fertile offspring.

This concept is known as the biological species concept. Therefore, if two populations can trace their ancestry back to a common lineage and have the potential to interbreed, they are considered to be the same species. Option A, stating that the two populations must be able to produce, is not sufficient for determining species identity. While the ability to produce offspring is important, it is the reproductive compatibility and ability to interbreed that truly matters. Option C, stating that their DNA must be an exact copy of another's, is not accurate. While individuals within a species share similarities in their DNA due to common ancestry, genetic variation and mutations are expected within a species. In summary, the key criterion for considering two populations as the same species is that they share a common ancestry and have the potential to interbreed and produce fertile offspring.

fur color

Explanation:

Nothing expect the color of fur can be determined by the parents.

Delta's role in regulating cell communication through the Notch signaling pathway is that Delta restricts cell communication to short distances within a developing embryo.

Chemical signals are typically used by cells to communicate. These chemical signals, which are proteins or other molecules made by the sending cell and released into the extracellular space, are frequently secreted by the cell. They can then travel to nearby cells by floating there, much like messages in a bottle.

During the development of fruit fly embryos, the receptor protein notch is visible on the surface of some cells. The protein delta, which is membrane-bound and expressed on the surface of neighboring cells, is the ligand for the notch. The intracellular tail of the notch protein separates from the rest of the protein when notch is activated by its ligand. Consequently, the intracellular tail can move to the cell's nucleus and change the way some genes are expressed.

Answer:D seems to be the most probable answer.

Explanation:

A:chromatin relaxes after cell cycle so ruled out

B:each side will have a single copy

C:nuclear envelope surrounds the whole genetic material, not individual chromosomes

At the end of the telophase stage of mitosis, a nuclear envelope will surround each cluster of identical chromosomes.​ Option D is correct.

During the telophase stage of mitosis, the cell undergoes certain changes in preparation for the production of two daughter cells. These changes include the following:

1. The chromatin, which is the loosely packed form of DNA, begins to condense into distinct chromosomes. This condensation allows for easier distribution of the genetic material during cell division.

2. Each side of the cell will have two copies of each chromosome. This is because during the earlier stages of mitosis, the chromosomes duplicated themselves, resulting in two identical copies of each chromosome. In telophase, these copies are segregated and will eventually be distributed to the daughter cells.

3. The nuclear envelope, which temporarily disappeared during earlier stages of mitosis, reforms around each cluster of identical chromosomes. This separation of chromosomes by nuclear envelopes ensures that the genetic material is contained within each daughter cell and prevents mixing.

Stella should place one flower in a similar container but not pump carbon dioxide into it. This would create a control group that is not exposed to the independent variable (increased carbon dioxide levels) and can be compared to the experimental groups.

To set up a control group for the experiment, Stella should place one flower in a similar container but not pump carbon dioxide into it. This option allows her to establish a baseline for comparison and isolate the effect of increased carbon dioxide on the growth rate of sunflowers.

A control group is a group in an experiment that serves as a standard of comparison. In this case, Stella wants to investigate the impact of increased carbon dioxide levels on the growth rate of sunflowers.

By having one sunflower in a container without the added carbon dioxide, Stella can compare its growth to the sunflowers exposed to varying levels of carbon dioxide.

By keeping all other conditions consistent, such as providing the same amount of water, mist, and fertilization to all the plants, Stella ensures that any differences in the growth rate of the sunflowers can be attributed primarily to the varying carbon dioxide levels.

This control group acts as a reference point to assess whether the observed changes in the experimental group (sunflowers exposed to different carbon dioxide levels) are indeed influenced by the increased carbon dioxide or other factors.

Analyzing and graphing the data from both the control group and the experimental group will allow Stella to determine the specific impact of carbon dioxide levels on the growth rate of sunflowers and validate or reject her hypothesis.

In animals, the process of respiration is aerobic respiration, exchange of gases takes place ( carbon dioxide leaving the cell, oxygen entering)

Single cellular organisms can exchange gases directly across their cell membrane through the process o diffusion.

Large animals cannot maintain gas exchange by diffusion across their outer surface. A respiratory surface is covered with thin, moist epithelial cells that allow oxygen and carbon dioxide to exchange. Those gases can only cross cell membranes when they are dissolved in water or an aqueous solution, thus respiratory surfaces must be moist.

Answer: a. 20

Explanation:

The incorrect match in the given options is option E: salivary glands - gastrointestinal tract organ.

The salivary glands are not a part of the gastrointestinal tract. The gastrointestinal tract is a long, hollow muscular tube that starts from the mouth and ends at the anus. It includes organs such as the mouth, oesophagus, stomach, small intestine, large intestine, and anus. These organs are responsible for the digestion of food, absorption of nutrients, and elimination of waste.

Accessory organs, on the other hand, are not a part of the gastrointestinal tract but play a significant role in the digestive system. These include the liver, pancreas, and gallbladder. The liver produces bile, which helps in the breakdown and absorption of fats. The pancreas secretes digestive enzymes that break down carbohydrates, proteins, and fats. The gallbladder stores and releases bile as needed for digestion. The salivary glands are actually considered an accessory organ, not a part of the gastrointestinal tract. The main function of the salivary glands is to produce saliva, which helps in the initial breakdown of food and makes it easier to swallow.

In the pancreas, beta cells secrete insulin, which lowers blood levels of glucose. So the correct option is d.

Insulin is a hormone that regulates the metabolism of carbohydrates, fats, and proteins in the body. It is produced by beta cells in the islets of Langerhans, which are scattered throughout the pancreas. The main function of insulin is to lower blood glucose levels by promoting the uptake and storage of glucose in the body's cells, particularly in the liver and muscle tissue.

When glucose enters the bloodstream, beta cells in the pancreas detect the rise in blood glucose levels and respond by releasing insulin into the bloodstream. Insulin then binds to receptors on the surface of cells, activating a cascade of intracellular signaling pathways that ultimately lead to the uptake and storage of glucose. In this way, insulin plays a crucial role in maintaining normal blood glucose levels, preventing hyperglycemia (high blood sugar) and its associated complications, such as diabetes.

On the other hand, alpha cells in the pancreas secrete glucagon, a hormone that raises blood glucose levels by stimulating the liver to convert stored glycogen into glucose, which is then released into the bloodstream. Thus, alpha cells and beta cells work together to maintain normal blood glucose levels by releasing opposite hormones, insulin and glucagon respectively.

(a) The volume in cubic millimeters is is 2.49 × 10⁻⁶ mm³. (b) The volume of exactly 1 × 10⁶ cells in liters (L) is 0.00249 L.

(a) To find the volume of the bacterial cell in cubic millimeters (mm³), we need to convert the given volume of 2.49 μm³ into mm³.
To convert from micrometers to millimeters, we need to divide the volume by 1,000,000 since there are 1,000,000 micrometers in a millimeter.
2.49 μm³ ÷ 1,000,000

= 0.00000249 mm³.
Therefore, the volume of the bacterial cell in cubic millimeters is 0.00000249 mm³.
(b) To find the volume of exactly 1 × 10⁶ cells in liters (L), we need to multiply the volume of one cell by the number of cells.
Volume of one cell = 2.49 μm³

= 2.49 × 10⁻⁶ mm³ (converted from μm³ to mm³).
Volume of 1 × 10⁶ cells

= (2.49 × 10⁻⁶ mm³) × (1 × 10⁶ cells).
Using the laws of exponents, we can simplify this calculation.
(2.49 × 10⁻⁶ mm³) × (1 × 10⁶ cells)

= 2.49 × 1

= 2.49 mm³.
To convert from millimeters cubed to liters, we need to divide the volume by 1,000 since there are 1,000 millimeters cubed in a liter.
2.49 mm³ ÷ 1,000

= 0.00249 L.
Therefore, the volume of exactly 1 × 10⁶ cells in liters is 0.00249 L.

(a) The volume of a certain bacterial cell is approximately 2.49 × 10-9 mm3.  (b) The volume of exactly 1 × 106 cells is 1 l.

(a) To convert the volume of a bacterial cell from cubic micrometers (μm3) to cubic millimeters (mm3), we need to multiply the volume by the conversion factor.

1 mm = 1000 μm, so 1 mm3 = (1000 μm)3 = 1,000,000,000 μm3.

Given that the volume of the bacterial cell is 2.49 μm3, we can calculate the volume in mm3 by multiplying it by the conversion factor:

2.49 μm3 × (1 mm3/1,000,000,000 μm3) = 2.49 × 10-9 mm3.

Therefore, the volume of the bacterial cell is approximately 2.49 × 10-9 mm3.

(b) To determine the volume of exactly 1 × 106 cells in liters (l), we need to multiply the volume of a single cell by the number of cells.

Given that the volume of a single cell is 2.49 × 10-9 mm3, and we want to find the volume in liters, we need to convert mm3 to liters.

1 mm3 = 1 × 10-6 l, so 1 × 106 mm3 = (1 × 10-6 l) × (1 × 106) = 1 l.

Therefore, the volume of exactly 1 × 106 cells is 1 l.

In summary,
(a) The volume of a certain bacterial cell is approximately 2.49 × 10-9 mm3.
(b) The volume of exactly 1 × 106 cells is 1 l.

Overall, it is important to use scientific notation when dealing with small volumes like those of bacterial cells to express the values in a more convenient and concise manner.
