how most of our excretory system is not dedicated to excreting; it’s dedicated to reabsorbing.

Answers

Answer:

Not all animals use the same routes or excrete their wastes the same way humans do. Excretion applies to metabolic waste products that cross a plasma membrane.

The excretory system works with the respiratory, endocrine, urinary and digestive system. It works with the respiratory system because it helps the lungs get rid of carbon dioxide and water vapors. It works with the digestive system to help get rid of wastes that you eat through the anus.

how magnification and resolution affect the appearance of objects viewed under a microscope​

Answers

Answer:

It allows to see objects more clearly.

Explanation:

Magnification and resolution greatly affects the appearance of objects that can be seen under a microscope​ because these two things make the specimen enlarge in size. Magnification refer to the process of enlarging the apparent size of something to see and observe it clearly while on the other hand, resolution is used to see more details about specimen that can be study in the microscope so we can conclude that both magnification and resolution has a great impact on the appearance of objects.

Answer the following questions:
⦁ What is the purpose/function of the Respiratory System?
⦁ What is the purpose of the tiny hairs called cilia in your nose?
⦁ What are the purposes of the pharynx?
⦁ What is the purpose of the epiglottis?
⦁ How is the respiratory system linked to the cardiovascular system

Answers

Answer:

1. The respiratory system allows us to breathe . They bring oxygen into our body and remove carbon dioxide from the body .

2. Tiny hairs called cilia protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.

3. The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).

4. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.

5. The heart pumps blood to the lungs for oxygenation and the lungs then give the heart back oxygen rich blood to be transmitted to the whole body

Which statement correctly
compares humidity in warm and cold air?

A. Warm air holds less moisture than cold air.

B. Warm air will always hold the same amount of moisture as cold air.

C. Warm air can hold more moisture than cold air.

D. Neither warm or cold air can contain water vapor.

Answers

Answer:I believe it is c, it makes the most sense to me. I apologize if I’m wrong

Explanation:

The statement which correctly compares humidity in warm and cold air is that warm air can hold more moisture than cold air. Thus, the correct option for this question is C.

What is Humidity?

Humidity may be defined as the amount of water vapor present in the atmosphere of living organisms or an ecosystem. If there is a lot of water vapor in the air, the humidity will be high. The higher the humidity, the wetter it feels outside. On weather reports, humidity is usually explained as relative humidity.

High humidity levels are more likely found in warm air. This is because warm air holds more water at higher temperatures. Due to this, warm air has the capacity to hold a lot of moisture.

But on contrary, fewer humidity levels are more likely found in cold air. This is because cold air holds less water at lower temperatures. Due to this, cold air does not have the capacity to hold a lot of moisture.

Therefore, the statement which correctly compares humidity in warm and cold air is that warm air can hold more moisture than cold air. Thus, the correct option for this question is C.

3.What are the functions of vacuoles, lysosomes, and the
cytoskeleton?

Answers

Answer:

In plant cells, vacuoles maintain water balance. Lysosomes break down excess or worn-out cell parts. The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement.

Explanation:

Storage, waste disposal and structural support  are the functions of vacuoles, lysosomes, and the cytoskeleton.

The following are the roles of vacuoles, lysosomes, and the cytoskeleton: Vacuoles are membrane-bound organelles that can be found in the cells of fungus, protists, and plants. They serve a variety of purposes, such as: Vacuoles have the capacity to store a wide range of materials, including waste materials, pigments, water, and nutrients. They control the osmotic equilibrium and aid in maintaining turgor in plant cells. Vacuoles in plant cells can be used as a storage space for a variety of waste materials and poisons that are damaging to the cell. They keep these molecules apart and stop them from harming other cell components. Support for structure: In plant cells, the huge central vacuoles press on the cell wall to support structure and preserve the form of the cell. Lysosomes are membrane-bound organelles that can be found in cells.
