Answer:
720 cm²
Explanation:
Formula for total surface area of a cylinder is;
TSA = 2πr² + 2πrh
We are told that the total surface area of cylinder A is 180cm². Thus;
2πr² + 2πrh = 180
Now, we are told that the height of cylinder B is twice the height of cylinder A.
This means that the length scale factor is 2. And as such the area scale factor is 2² = 4.
Thus area of cylinder B = 180 × 4 = 720 cm²

Looking at the chart provided, the students need to develop a classification scheme to distinguish plant and animal cells. The presence of which of the following structures/organelles would be most useful for this purpose?
Answer:
The correct answer would be - cell wall and chloroplast
Explanation:
The cell wall and chloroplast both are the main characteristic feature of the plant if present together in any cell of organisms. In most of the cells other than plant cells, the cell wall and chloroplast does not present together.
The cell wall is the outer rigid structure of plant cells made up of cellulose provide support and injuries. Chloroplast is the major and important structure of the plants responsible for their color and production of glucose by the process known as photosynthesis.
These two organelles would be most useful as all other organelles are similar and found in all cells given in the chart.
Think about the concept of evolution.
Would you say this is a hypothesis or a theory? Think about the difference between a theory and a hypothesis and try to apply it to the concept of evolution.
Definitions:
In science, a theory is more like a scientific law than a hypothesis. A theory explains a set of observations or events. It must be verified multiple times by many different scientists. One scientist cannot create a theory on his or her own.
A hypothesis is an educated guess based upon observation. It is an explanation of a single event based upon what is observed. A hypothesis has not been proved but can be supported by experimentation.

D. It provides a means of asexual reproduction.
which target organ releases glucose into the blood-stream as a result of the action of adreline?
a) adrenal gland
b) kidney
c) liver
d) pancreas
The answer for this is the liver
The target organ that releases glucose into the bloodstream as a result of the action of adrenaline is the liver, which is present in Option C, as the liver stores the glucose in the form of glycogen.
What is the importance of glycogen in the body?Glycogen is a polysaccharide that is stored in the liver and muscles of the human body and plays a crucial role in maintaining the body's energy as well as glucose homeostasis. During exercise or physical activity, glycogen is broken down into glucose, which is then released into the blood as fuel; this is regulated by hormones such as insulin and glucagon and prevents hyperglycemia.
Hence, the target organ that releases glucose into the bloodstream as a result of the action of adrenaline is the liver, which is present in Option C, as the liver stores the glucose in the form of glycogen.

stomach, heart, red blood cell, muscular system.
Answer: Muscular system because it is a complex body system, the others are organs in cells
Answer:
The muscular system
Explanation:
To make it simple, you know how you have muscles throughout your body? This makes it quite complex, given that it has to be able to function with so many other muscles working together.
The heart just pumps blood, the stomach digests, and the red blood cells carry oxygen throughout the bloodstream. Simple, right?
