Answer:

The correct answer is option D.

Explanation:

Osmosis refers to the procedure by which the molecules of water move from the area where they are highly concentrated to the area where they are present in low concentration via a semipermeable membrane. One use of osmosis is that it provides support to plants.  

A hypotonic solution refers to a kind of solution, which possess more molecules of solvent, in the given case it is water and fewer molecules of solute. The freshwater is hypotonic to plant cells, therefore, the cells of the plant captivate water osmotically, and its size increases and become turgid. This produces an external opposite pressure, which is equivalent to the wall pressure that maintains the plant's upright position.

sashaice [31]

Answer:

Neural networks

Explanation:

The neuron is the structural and functional unit of the nervous system. The neuron is also known as a nerve cell. The neuron is the largest cell of the body that helps to communicate or transmit signals. A neuron has an axon body, dendrites, and terminal region. The transmission of the signal from one neuron to another through the axon terminal.   Large numbers of neurons are present in the human body system that coordinates the whole body system. Neural networks contain a massive amount of neurons whose architecture is based on neurons. So, the correct answer to the given question is neural networks that use massively parallel systems based on neurons.

Several biology students are counting kernels in an ear of corn. They count a total of 420 kernels: 242 purple wrinkled, 84 purp
s2008m [1.1K]
The answer is C) 9:3:3:1

This looks like a dihybrid cross where the expected phenotypic ratio is 9:3:3:1. However, in nature, the numbers cannot be absolut. Let's check it out:
242 purple wrinkled
84 purple smooth
70 yellow wrinkled
24 yellow smooth

Divide all by the smallest number:
242 purple wrinkled / 24
84 purple smooth / 24
70 yellow wrinkled / 24
24 yellow smooth / 24

We have 
10.1 purple wrinkled which is near to 9
3.5 purple smooth which is near to 3
2.9 yellow wrinkled which is near to 3
1 yellow smooth
