From the results in the experiment the best conclusion is : ( B ) they are not valid because the student did not control all the variables that can affect plant growth

The growth variables such as amount of light and amount of water need for the plants to grow effectively are not controlled in the experiment. The first group was hand watered while the second group was watered with a sprinkler therfore the amount of water reaching both groups are not the same therefore the experimental conclusion is not valid.

Answer:

C

Explanation:

During a process called denitrification, nitrogen in gas forms, like nitrous oxide, are being released. Denitrification occurs if the nitrate is used when bacteria in the soil performs respiration.

The sum of the decreases of the electric potential along the path will be 2.004V.

From the complete information, the total current(I) is given as:

= 2/(4 + 3 + 5)

= 2/12

= 0.167A

V3 = I × 3

= 0.167 × 3

= 0.501V

V4 = I × 4

= 0.167 × 4

= 0.668V

V5 = I × 5

= 0.167 × 5

= 0.835V

Therefore, the sum of the decreases of the electric potential along the path will be:

= 0.501V + 0.668V + 0.835V

= 2.004V.

Photosynthesis takes place in Chloroplasts

In plants, the process photosynthesis occurs in chloroplasts which contain the chlorophyll. The chloroplast is seen on the mesophyll of the leaves. So in the given figure, chloroplast is present in the part 'E'. The correct option is E.

The process by which the autotrophs convert light energy into chemical energy which is later used to perform the cellular activities is defined as the photosynthesis. The chemical energy is stored in the form of sugars, which are produced from water and carbon-dioxide.

Photosynthesis generally takes place in the specialized structure called the chloroplasts which consist of chlorophyll. It is the chlorophyll which absorb light energy from the sun. The majority of chloroplasts is present in the leaves which absorbs sunlight for the photosynthesis to occur.

So chloroplast is found in all green plants and algae. They are called the food producers of plants. This cell organelle is not found in animal cells.

Thus the correct option is E.

It's important to use hard agar with soft agar overlay because The hard agar underneath the soft agar overlay is where you make a lawn streak of your bacteria.

A trusted technique for determining viral concentration in relation to infectious dose is the plaque assay. In order to perform the test, a monolayer of virus-infected cells must be counted to determine how many plaque forming units (pfu) were generated.

When a virus-infected cell lyses, plaques form, which trigger a cycle of surrounding cell lysis and infection. Crystal violet staining of the preserved cell monolayer allows for the visualization of plaques. 

The plaque assay was initially created as a virological assay to count and measure bacteriophage infectivity. Later, it was used to count viruses that infect mammals as well.

The technique's fundamental premise is to assess a single infectious virus' capacity to develop a "plaque" on a confluent monolayer culture of cells.

Therefore, It's important to use hard agar with soft agar overlay because The hard agar underneath the soft agar overlay is where you make a lawn streak of your bacteria.

Answer:

Contractile vacuole

Explanation:

Contractile vacuole pumps out excess water and wastes in a paramecium.

The structure that pumps out excess water and waste in a paramecium is called the contractile vacuole. The contractile vacuole is a specialized organelle that collects excess water and waste materials from the cell and then contracts and pumps them out of the cell through a pore in the cell membrane.

Paramecium is a single-celled organism that belongs to a group of organisms called protists. Like other cells, a paramecium must maintain a proper balance of water and solutes inside its cell to function properly. However, because paramecia live in freshwater environments that have a lower solute concentration than the cell, water tends to move into the cell by osmosis. If too much water enters the cell, it can cause the cell to burst, so the paramecium has developed specialized structures to help regulate the movement of water.

Hence, the structure that pumps out excess water and waste in a paramecium is called the contractile vacuole. The contractile vacuole is a specialized organelle that collects excess water and waste materials from the cell and then contracts and pumps them out of the cell through a pore in the cell membrane.
