Answer:
This question lacks options, the options are:
A) 100 ml Beaker
B) 250 ml Erlenmeyer Flask
C) 250 ml Graduated Cylinder
The answer is B). 250 ml Erlenmeyer Flask
Explanation:
Several types of glasswares are used in chemical laboratories for performing processes like mixing, heating and stirring of chemicals. In this question, Dr. Malani Mackey who works for a pharmaceutical company is trying to develop a cancer drug by making a mixture of L-histidine, polysorbate 80, and sucrose. This mixture is required to be heated and stirred (shaked) during the mixing. Hence, a glassware adapted for this purpose must be used.
- Erlenmeyer Flask, also known as Conical flask is a laboratory flask named after its conical base/bottom. This glassware is used to mix and even heat chemicals in the laboratory. Due to its cone-shaped body coupled with a long cylindrical neck, the contents in the Erlenmeyer Flask can be shaked or stirred without spilling them. This property gives the ERLENMEYER flask an edge over the BEAKER (has a large open mouth) when used for stirring purposes.
The Graduated cylinder is best suited for making precise measurements of liquid chemicals, hence, it is not an appropriate glassware for heating and stirring.
<u>Answer:</u>
Area receives little precipitation.
<u>Explanation:</u>
- Arid climate is a type of climate that receives less than 25.4 cm of rainfall throughout the year.
- Desert climate is called as arid climates. Rainfall in arid climates is usually irregular but when rainfall occurs then it will be huge with thunderstorm.
- Many plants and animals found in that climate adopt themselves from rare rainfall and they remain inactive during most of time of the year and active only on the time when rainfall occurs.
<span>Dry beans and legumes fall under the nutrient classifications
plant proteins.
</span>This nutrition group includes beans, lentils, soybeans, peanuts and peas. It is very important vegetarians or individuals who consume limited amounts of meat to consume plant proteins, because they replace meat and poultry.
Answer:
The genes need to be on different chromosomes.
Explanation:
In the first cross, the ratios are equal at 25 percent but for the offspring, there is no balance. These results can be caused by the gene that is observed being on the same chromosomes, in which case it's effects will not be observable in the offspring.
I hope this answer helps.
