B. & C.
A is incorrect because the most complex level of organization is the organism itself, as a whole.
D is incorrect because a cell is what composes different tissues, it isn’t made of different tissues.
——————
B. The cell is the most basic structural unit of life. They are independent and can perform processes like excrete waste, take in nutrients etc.
C. There are so many different cell types such as muscle cells, stomach cells, bone, neurons, etc. meaning they “specialize” in one thing such as being a stomach cell.
Hope this helps!
Answer:
1, 2, and 5
Explanation:
Viruses are pathogenic microorganisms that lack the ability to thrive and reproduce outside of a living host cell. Their structure is simple - they consist of a nucleic acid molecule surrounded by a protein coating and sometimes an outer envelope. They are too small to be seen by a light microscope.
As they are way smaller than living cells, viruses are smaller than organelles as well. They don't have their own metabolism. Their reproduction is not based on division. They don't have any organelles, including the cytoplasm. They are surrounded by a protein coat called the capsid.
Based on this information, we can see that the correct statements are statements 1, 2, and 5.
The two structures that could be found only in plant cells are chloroplast and the cell wall. As these two structures are not present in the animal cells, therefore the chloroplast and cell wall are the two positive identifications of a plant cell under the microscope.

Gigantism is a condition caused by excessive secretion of STH(somato trope hormone) before puberty. Individuals reach heights of about 2 meters.
Dwarfism(hypophyseal dwarfism) is caused by hyposecretion of STH before puberty. Individuals reach heights of about 1,20-1,30m
