How will the stomata look with high water pressure

Biology
1 answer:
dalvyx [7]3 years ago
3 0
The stomata of leaves are surrounded by guard cells. The guard cells help the leaves to regulate the rate of transpiration of water from the leaves by opening and closing the stomata. When water enter the guard cells, they swell and bulge and this makes the stomata to open. So, with high water pressure, the guard cells will stimulate the stomata to open. The reverse will be the case if the water pressure is low.

Organisms with advantageous adaptations are more likely to survive and reproduce than organisms without the advantageous adaptat
expeople1 [14]

Natural selection refers to the phenomenon by which the species in a population possessing the tendency to get adapted in a condition enhance in numbers in comparison to those who exhibit fewer adaptation capacities over a number of generations.  

In other words, it can be stated as the non-random and differential development of distinct genotypes function to sustain favorable variant and to eradicate less favorable variants. Some of the conditions are required for the process of natural selection to take place.  

These are heredity, reproduction, variation in individual characters, and variation in the fitness of organisms among the members of the population. If the conditions are met, then the phenomenon of natural selection occurs by default.

Mila [183]

Answer:

The correct answer will be-

1. Observation-option B.

2. Hypothesis-option A.

3. Experiments- option C.

Explanation:

A scientific method involves various steps to explain a natural phenomenon of nature. It begins with making an observation which leads to asking the scientific question. The researcher does background research and proposes a hypothesis which could be tested through experiments. The experiments could prove or disprove the hypothesis based on the results.

In the given question the observation made is an equal amount of A and T and G and C are observed. It leads to a hypothesis which shows that this could have happened due to the winding of two strands of DNA and the experiments was performed through X-ray diffraction pattern.

Thus, the selected options are the correct answer.

What factor caused the appearance of oxygen?
Nookie1986 [14]

Answer:

The appearance of free oxygen in the Earth's atmosphere led to the Great Oxidation Event. This was triggered by cyanobacteria producing oxygen which developed into multicellular forms as early as 2.3 billion years ago

Explanation:

To clarify what I said here are some questions to help!

How did oxygen first appear?

Whiffs in the air is how oxygen first appeared billions of years ago.

For the most part, scientists agree that oxygen, though lacking in the atmosphere, was likely brewing in the oceans as a byproduct of cyanobacterial photosynthesis as early as 3 billion years ago

When was oxygen found?

2.33 billion years ago

Since its first appearance 2.33 billion years ago, oxygen accumulated in high enough concentrations to have a weathering effect on rocks just 10 million years later.

I don't know if this helped you but if it does, please let me know!
