Biology
1 answer:
hichkok12 [17]3 years ago
7 0

Answer:

Oxygen is obtained from photosynthesis process.

Explanation:

Oxygen is one of the most important element required for survival of living organism. Living beings inspire oxygen and expire carbon dioxide which is collectively called as respiration and is considered as most important biological process.

Plants prepare their own food through the process called photosynthesis. It is process through which the plants uses carbon dioxide and water as reactants and gives out glucose and oxygen as the end product.

The released product is sugar and gas, in which the sugar is consumed as food by other living organism and the gas called oxygen is used for respiration and other biological process. Thus it can be inferred that oxygen is obtained from process called photosynthesis.

Ymorist [56]

Answer:

Plasmolysis

Explanation:

In the image 1 the cell is having sufficient quantity of water leading to a turgid cell.

The image 1 plant cell is in a dilute solution in which water enters into cell from external medium.

The image 2 plant cell is exposed to a solution which is high concentrated solution.

Due to this high concentrated  solution the water present in  the cell is send out by exosmosis.

Due to loss of water from plant cells the protoplasm in plant cell shrinks in which cell membrane gets separated from  cell wall.

This shrinkage of protoplasm by loss of water is called plasmolysis.

What theory dramatically improved geologist's ability to predict where certain ore deposits were formed? Select one:
mrs_skeptik [129]

Plate tectonics is referred to a geology theory, which explains the movement of earth’s lithosphere.  This theory suggests that the earth’s lithosphere is made up of many plates, and these plates move on each other causing collision of the plates or sometimes separation of the landmasses.  

Sometimes, the movements of the plate occur in such a way that the surface of the earth is buried underground. Even in normal circumstance, some of the surface materials buried underground. So, by studying the type of things existed on the surface in past, one can predict the abundance of a specific substance underground.  

Hence, the correct answer is option b. – Plate tectonics.

How does water clarity indirect effects on other species in food chain?
Vladimir [108]

Answer: The effects of which are devastating to human life, flora and fauna, which depend on these resources for their survival. Contamination of water causes disruptions of food chains and destruction of ecosystems. A deadly by-product of this water pollution is the spread of water-borne diseases such as cholera, typhoid etc.

Which two structures are found ONLY in plant cells?
Naya [18.7K]


The best answer is  C.

Plant cells are surrounded by a cell wall and have chloroplasts whereas animal cell do not.

The cell wall is  a covering that is rigid whose main purpose is to protect the cell and give structural support as well shape to the plant cell. The equivalent of a cell wall in animal cell is the cell membrane, which has distinct differences from the plant  cell wall.

Chloroplasts are plant  cell organelles which carry out photosynthesis by which plants make their own food. These are absent from animal cells because animals do not make their own food, they ingest it from external sources.
