PLEASE HELP QUICK WILL MARK BRAINLIEST IF CORRECT: Agriculturalists investigating a poorly growing onion crop discovered it was infected with a fungal pathogen. The fungus secreted a lectin-like protein in the soil surrounding the onions’ roots. Lectins often accelerate mitosis in root systems, but this abnormal growth creates weaker plant tissues. Fifty cell samples were observed for the struggling onion crop. The observed number of cells in each part of the cell cycle are shown below: (picture 1)

a) State the null and alternative hypothesis related to the data.
b) Calculate the chi-square values for interphase and mitosis using the samples as the observed values (o) and trial 1 in table 3 as your expected data (e).
Using the chi-square table, determine the critical value for interphase and c) mitosis of the struggling onion crop using the chi-square values in (b).
(picture 2)
d) Based on the chi-square and critical value, draw a conclusion about the null hypothesis.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
