Astudent notices that when bananas are kept near other fruits, the other fruits ripen faster. she wonders what causes the other fruits to ripen more quickly and thinks that bananas must have an influence on the ripening process. she decides to perform an experiment. she gathers bananas and apples and places an apple by itself at location a and an apple next to a banana at location b. she then waits for five days and records the how ripe each apple is. what would be the next step in this experiment? a. make observations and draw a conclusion b. construct a hypothesis and record data c. analyze the results and make a conclusion d. ask questions and construct a hypothesis

answer:

bananas produce an ethylene gas that functions as a plant hormone. the plant's exhibit genes known as ctr1 and etr1, which monitor lots of other genes taking part in aging, growth, and cell death. this production of hormone elevates the ripening process.  

in the given case, the next step of the student would be to analyze the results and make a conclusion, as she has already made an assumption or hypothesis and has conducted the experiment to observe the result.  

answer; i believe that the correct answer is(d) nondisjunction during meiosis;

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
