Answer:
1938
Explanation:
Matthias Schleiden was a German botanist who studied the plant's cell and its structure under the microscope. In 1938 he contributed to the cell theory and stated that every tissue present in the plant is made of or cells and an embryonic plant is produced from one single cell.
In 1939 another scientist Theodor Schwann proposed the same conclusion after studying animal cells and concluded that the basic unit of life is cell and every organism on earth is made up of one or more cells. Therefore Theodor Schwann and Matthias Schleiden have great contribution in cell theory.
Answer:
The things needed to be checked before the cell moves through the stages of mitosis are 1 DNA of cell undergoing mitosis 2 chromosome number of the cell moving through the stages of mitosis,3 Amount of RNA and protein present in the cell undergoing division.
Explanation:
DNA of the cell undergoing mitosis
It is very important thing to note that cell cycle regulatory mechanism should check that the cell undergoing mitosis should have normal DNA.Cells with damaged DNA are restricted to enter mitotic phase.
Chromosome number of the cell
The most thing of the interphase regulation to check that DNA has replicated once per cycle .This is very very important thing to maintain normal chromosome number of the cell entering mitosis.
Amount of RNA and proteins synthesized
The G1 and G2 phase of the cell cycle helps in the synthesis of RNA and protein molecules.Significant amount proteins should be present in the cell undergoing mitosis.
Monday is the best day since there is no wind. To conduct canopy fogging, the ideal conditions would be windless and calm, so as not to disrupt the fogging operation.
<h3>What is canopy fogging?</h3>
During fogging, a petrol-powered fogging machine is used to disseminate a non-hazardous natural pyrethroid pesticide into the forest canopy.
The missing image of the question is attached below.
As per the image description, Monday is the best day since there is no wind. To conduct canopy fogging, the ideal conditions would be windless and calm, so as not to disrupt the fogging operation.
Thus, Rachel should conduct canopy fogging on Monday according to the given scenario.
