Answer:

C. removing water and waste

Explanation:

Exocytosis occurs when a cell produces substances for export, such as a protein, or when the cell is getting rid of a waste product or a toxin.

Answer:

[tex]\boxed {\boxed {\sf C. \ Removing \ water \ and \ waste}}[/tex]

Explanation:

We are asked to find a description for a cell undergoing exocytosis. First, let's define the process.

Exocytosis is a type of active transport, so ATP or energy is required to initiate and complete the process.

This process moves substances from the inside of a cell to the outside. Molecules are packaged into vesicles. The vesicle moves to the cell membrane and attaches. The vesicle fuses with the membrane and the molecules inside the vesicle are released.

Essentially, substances are removed from the cell. This is especially useful because it can rid the cell of any waste or excess water. Therefore, the correct answer is choice C.

Answer:

Option(A) carbon ,hydrogen,nitrogen,oxygen and sulphur.

Answer:

A.carbon, hydrogen, nitrogen, oxygen, and sulfur

Explanation:

There are five elements that are essential to life. These are Carbon, Hydrogen, Nitrogen, Phosphorous and Sulfur, or CHNOPS for short. We can see that only option A has nitrogen listed. Nitrogen is absorbed by plants through the soil, and by animals through food. It is absolutely essential for many forms of life, especially plants and animals. Many biomolecules contain Nitrogen. Only one choice on this list contains nitrogen and that is option A. Therefore option A is the answer.

Muscle cells can contract in response to stimuli. Moreover, muscle cells also have a large number of mitochondria and ribosomes for energy requirements and protein synthesis, respectively.

The correct answer is option C) The new mice population size is a result of density-independent regulation.

The carrying capacity might be affected by different factors, known as limiting factors, which might be a result of the population density (for example, competition) or might be density-independent. This last case refers to dense-independent factors, and among these, we can mention human impact or natural disasters (fires, volcanic eruption, flooding). Natural disaster causes damages in an ecosystem, reducing the available resources such as food or shelter, and consequently decreases the number of individuals. Natural disasters reduce the carrying capacity of the environment

In the exposed example, mice got to stabilize on the island. The population had enough food and no predators. But the occurrense of the huricane reduced drastically the population size. This is an example of a natural dissaster acting as a limiting dense-independent factor affecting the population size.

Answer:

Classifying and characterizing various types of collection helps us to identify and understand the capabilities and limitations of each type.

Explanation:

By understanding these factors, we are better able to request support, layer collections, and provide a complete collection plan that best addresses our intelligence gaps. Collection strategies ultimately start with these gaps. By understanding all of your available collection capabilities, you can more effectively manage these assets to accomplish the mission. In most cases, you will not be able to have every type of asset or collection medium under the sun, so it becomes even more critical to understand the strengths and weaknesses of those available. Doing so will help a collection manager most effectively utilize the assets available to them to accomplish the collective organizational mission or end state. Without characterization and classification, you cannot fully understand and thus employ the myriad of tools available effectively (Found on a site not mine)

Taxonomy allows us to organize and categorize collections based on their characteristics, which makes it easier to understand the various types of collections that exist and to compare them.

All of the world's plants, animals, and microorganisms are included in taxonomy, which is the science of naming, describing, and classifying species.

For a number of reasons, taxonomy, or the classification of collection kinds, is crucial.

Secondly, taxonomy enables us to classify and organize collections based on their traits, which facilitates comprehension of the numerous sorts of collections that exist and allows for simpler comparison.

To ensure that collections are properly managed, preserved, and available for future generations, taxonomy is an essential tool for understanding the development of collection strategies, technologies, planning, and techniques of collecting.

Thus, it is important to have a taxonomy or classification of types of collection.

Answer:

Plants make their own food from sunlight, water, and carbon dioxide (part of the air). Making food like that is slow, so if they moved around too quickly, they'd starve to death. So, though they do move, it's usually very slowly.

Animals get their food from plants or from other animals. Moving around is a way for them to get more food, not just to use it up. It's also a way to avoid getting eaten.

(Even plants which appear to "eat" food, such as a venus flytrap, are actually only getting vitamins and minerals that way, not extra energy.)

Some of the aspects that help you determine whether a study is rigorous are questions and hypotheses that can be answered, adequated method use, and bibliography.

Rigorous is a term that refers to a quality that focuses on accuracy and precision to comply with norms, precepts, and pre-established rules. This term is widely used in science to refer to the precision of a study or investigation.

Therefore, when it is established that a study is rigorous, its attributes must be taken into account, such as:

- Questions and hypotheses that can be answered: This aspect refers to the investigator having the ability to limit his study so that it is appropriate to do so and does not include too much information that makes his study "impossible".

- Adequated methods use: This refers to using the appropriate methods to reach feasible conclusions, for example, methods of observation, deduction, induction, among others.

- Bibliography: This refers to the research or study being supported by reliable sources so that it is as accurate as the information it provides.

From left to right, the correct order of the minerals from the least hard to the hardest is ⇒ Graphite, Talc, Gypsum, Calcite, Fluorite, Apatite, Magnetite, Pyrithe, Feldespat, Quartz.

Theoretical frame:

Hardness is one of the physical properties of minerals and is a significant one when identifying and recognizing them.

Hardness measures the resistance level of a surface to abrasion. In the specific case of minerals, it measures how minerals resist being scratched or penetrated.

The hardness level is determined by an attempt to scratch or produce a mark on an unmarked surface using sharp elements, such as nails, copper coin, glass, or a steal knife. Notice that these elements also vary in their hardness.

There are different methods used to define hardness, and they are not comparable to each other. The Mohs hardness method defines an ordinary qualitative scale that characterizes the mineral according to their resistance to being scratched by a harder element.

According to the Mohs hardness scale, the level in which the given minerals are placed is as follows,
