D: causes to fall in landslides

Answer:

The correct answer is 4.ecosystem.

Explanation:

An ecosystem is a system, that is, a set of elements that interact with each other, in which such elements are: physical environment, living beings and their interactions (predator-prey, parasite-host, competition, symbiosis, pollination, distribution of seeds , etc.) The interrelation between living beings (competition, parasitism, etc.) occurs through cycles of matter and energy flows on which the functioning of the entire ecosystem depends.

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

B

Explanation:

Answer:

4l = 24

so l=6

now

l*l =6*6

= 36 square cm

Answer:

36cm²

Explanation:

Perimeter of a square = 4x (sum of all 4 sides)

Perimeter = 24 cm (given)

[tex]\implies [/tex]4x = 24

x = 24/4 = 6 cm

Now, area of a square = (side)²

Area = (6)²

= 36 cm²

Answer: Your correct answer would be both A & B.

Explanation: A is the correct answer because both of these models are in fact models of our solar system. The geocentric model had Earth at the center of the solar system with all the other planets and sun rotating around us. The heliocentric model is the accepted model of our solar system today with the sun at the center and planets rotating in slightly elliptical fashions around it due to gravitational pull. B is also correct because as I just explained, both models position Earth in relativity to the sun though both models vary greatly. The aim of both of these models was to specify where Earth was exactly in the solar system. I hope this has been of use to you! Please do not hesitate to ask if you have other questions :)

The two correct statements about the geocentric and the heliocentric model are:

The geocentric model

The geocentric model has the assumption that the earth is at the center of the universe. The sun and the planets are said to revolve around the earth in this model

The heliocentric model:

The heliocentric model has the assumption that the sun is at the center of the universe. The earth and the planets revolve around it.

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.

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.

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.
