The invention that allowed scientists to study cells for the first time is the Microscope
He used Pea plants to help him find the laws of inheritance. He crossed homozygous (AA) tall plants with short (aa) plants and found that all of the off spring were tall, due to the fact that tall is dominant and short is recessive. He then conducted another experiment where all the offspring mated (all offspring were heterozygous (Aa)) And produced the F1 generation and 25 percent of the plants were short (use a punnet square to see why) and 75 percent were tall.
I hope this response helped :) If u have anymore q about mendelian genetics pls lmk !
One major lab accident was of fire where gases were exposed to heat.
<u>Explanation:</u>
Accidents that occur in the laboratory which lead to some mishappening are known as the lab accidents. The reasons for such accidents may be many like fire, chemical spills, personal injuries and so on. To avoid all this, there should be proper check and focus while working in the lab.
One of the major lab accidents was of the fire when gas was exposed to heat. The chemical involved in this accident was the use of methane. The type of personal protective equipment worn at the time of accident was protective eye-wear and the lab coat and the lab gloves. To avoid such kind of accidents, people in lab should be very careful and it should be made sure that there are proper equipment in case of any mishap.
Answer:
The term which can be used for this species is psychrophile. Psychrophilic bacteria are the bacteria which love to grow at low temperature. The optimum they like to grow is 15°c and the highest temperature they grow is 20°c.
The minimal temperature a psychrophile grows is zero degree Celsius so a psychrophile can grow easily at refrigeration temperature which is 4°c. Phychrotrops are bacteria which can grow at cold temperature but tends to grow well above 15-20°c.
Therefore according to this question, there was no growth at 37°C and 50°C, very slight growth out on the benchtop, and abundant growth at refrigeration which determine that the species is a psychrophile.
