H2O is classified as a chemical compound.
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.
Answer: The tissue structure of the liverworts restricts them to a type of environment that affects their size.
Explanation:
Nonvascular plants, also called the Bryophytes in Kingdom Plantae, are simple plants that grow in damp places on land and as the name implies, are non vascular plants( that is, they lack vascular tissues). There are three types of nonvascular plants which includes:
--> Mosses
--> liverworts and
--> hornworts.
Liverworts are restricted to a particular size through the type of tissue they have ( non vascular) because it predisposes them to lack conducting vessels like the phloem and xylem found in vascular plants which aids in conducting water and food to various parts of the plants. Also they do not grow tall like the vascular plants because they lack the qualities that will enable them do so, such as roots, stems and leaves.
Nonvascular plants are low-growing, reproduce with spores, and need a moist or damp environment.
Because gravity is acting straight down. It does not act side to side. On the other hand, air resistance acts (in this case) only side to side, in the opposite direction of the movement. Even if the two are the same size, they are not acting in the opposite direction of each other, so they do not "balance each other out," i.e., do not stop each other.
Answer:
We exist to see if we can past the test God gives us through our lifetime here on Earth. We exist because God put us here on Earth, with the first man being made of clay, and the first woman being made of the clay from the ribcage of the man.
Explanation:
We face many tests in our lives, whether we notice them or not. We are then given praises for passing tests and gain sins for failing tests and doing wrong.
Tests can come in many ways, such as picking up something that someone dropped, being polite, controlling anger, staying focussed, and more.
