A drought causes a wildfire which destroys a forest. Which Earth systems interact during this process? (1 point) Select one: a.

Ne4ueva [31]

Answer:

It is the biosphere and hydrosphere that interact when a drought causes a wildfire that destroys a forest. 

Explanation:

Hydrosphere consists of all the water bodies of earth like oceans, seas, rivers, lakes etc. a drought occurs due to scarcity of water which affects the hydrosphere. The scarcity of water causes plants and trees to dry up and become more prone to catching fire

Biosphere includes all the living organisms of the earth. It includes plants, trees, birds, insects, animals etc. A drought dries up a whole area and a small fire that starts up somewhere in a forest would then engulf the whole forest.

This table shows characteristics of four unknown protist species.

Vikki [24]

Correct answer: D). 4

All animals are eukaryotic, multicellular and possess a complex tissue. They are heterotrophs it means they do not prepare their own food, they eat living and dead organisms and they may be herbivores, carnivores, omnivores or parasites.

The five steps of nutrition in animals are ingestion, digestion, absorption, assimilation, and Egestion.

Hence, the most suitable answer would be option D.

If plants are grown for several days in an atmosphere containing 14CO2 instead of 12CO2, one would expect to find?

Roman55 [17]

Answer:

More CO2 molecules are responsible for production of more carbohydrates.

Explanation:

Plants make their carbohydrates (food) by process called photosynthesis. CO2 is responsible for Carbon Fixation in Calvin cycle during photosynthesis. The more CO2 is utilized the more carbohydrates can be manufactured.

Thus, if plants are grown for several days in atmosphere where more 14CO2 is available as compared to 12CO2 then more food (starch-carbohydrates) production can be accomplished.

What is phagocytosis? It is a type of endocytosis in which a cell engulfs a particle in a vacuole. It is a type of exocytosis in

Radda [10]

Answer:

It is a type of endocytosis in which a cell engulfs a particle in a vacuole.

Explanation:

There are 2 processes by which cells uptake and release materials.

These are:

Exocytosis
Endocytosis

EXOCYTOSIS:

It is a process by which cells release materials inside them to the external environment.

ENDOCYTOSIS:

It is a process by which cells bring materials inside them from the external environment. It is the opposite of exocytosis.

Endocytosis is of different types including phagocytosis, pinocytosis and receptor-mediated endocytosis.

PHAGOCYTOSIS

Phagocytosis involves the phenomenon in which a cell engulfs a particle in a vacuole. The particle may be a disease causing microorganism, or cell of the body. This process can be conceptualized as "cellular eating".

EXAMPLE:

Macrophages consuming bacterium Mycobacterium tuberculosis is an example of phagocytosis.

PINOCYTOSIS:

It is the process by which cells uptake liquid substances. It can be thought of as "cellular drinking"

RECEPTOR-MEDIATED ENDOCYTOSIS:

It is a process by which cells uptake hormones, metabolites and other substances. It is performed by cells which possess a receptor for that substance. It involves the inward invagination of cell membrane after the binding of substance and its receptor.

Coming back to answer choices,

It is a type of endocytosis in which a cell engulfs a particle in a vacuole.

This is the correct answer choice as it describes the process of phagocytosis.

It is a type of exocytosis in which a cell engulfs a particle in a vacuole.

This is the wrong answer choice as phagocytosis is an endocytic process.

It is a type of endocytosis in which extracellular fluid is taken into the cell in tiny vescicles.

This is the wrong answer choice as this answer choice describes the process of pinocytosis and not phagocytosis.

It is a type of exocytosis in which extracellular fluid is taken into the cell in tiny vesicles.

This is the wrong answer choice. It does not describe phagocytosis. Phagocytosis is an endocytic process and involves the internalization of cells and pathogens.
