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?
Answers
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.

50. Identify which of the following is the most complex and explain your answer choice:
stomach, heart, red blood cell, muscular system.
Answers
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?

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
Answers
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.

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.
