I’m pretty sure it’s the second one
Answer:
Contains large polytene chromosome that permit visual inspection of genomic events.
Were used to study the genetic effects of mutations.
Were used to establish the concept of chromosomal inheritance.
Explanation:
<em>Drosophila melanogaster </em>is a model organism that is used by scientists to study the genes and effect of a mutation on the genes. Drosophila is used as a model organism as it has a very short life cycle and the offspring can be produced in a short duration of time.
Because of these characteristics, Thomas Hunt Morgan wanted to study the factors of inheritance on the <em>Drosophila</em> and concluded in the form of the chromosomal theory of inheritance by the effect of mutation on genes that lead to linkage mapping.
Also, the salivary gland of fruit fly contains the polytene chromosome which allows us to look into the gene events.
Thus, the selected options are correct.
It's a prokaryotic cell type.
Answer:
NO
Explanation:
The animal cell and plant cell are both eukaryotic cells. Eukaryotic cells are the type of cells that contains membrane-bound organelles, such as the nucleus, mitochondria, Golgi apparatus and a cytoskeleton.
The cytoskeleton, which is composed of microfilaments, internal filaments, and microtubules, <u>is present in both the animal and plant cells.</u>
However, some of the organelles that are not present in both the animal cell and the plant cell are centrosome and lysosomes.
<u>The </u><u>lysosome</u><u> is present only in the animal cell.</u>
