QUESTION 8

In eukaryotic cells, ________ are energy-producing organelles that contain DNA.

chromosomes

lysosomes

mitochondria

nucleoli

nuclei

QUESTION 9

Name the single individual whose work in the mid-1800s contributed to our understanding of the particulate nature of inheritance as well as the basic genetic transmission patterns. With what organism did this person work?

Calvin Bridges; Drosophila

Thomas Hunt Morgan; Drosophila

Gregor Mendel; Pisum sativum

George Beadle; Neurospora

Boris Ephrussi; Ephestia

Expert Solution

Answere :

Question 8 : The correct option is mitochondria

Explanation : Mitochondria are are energy-producing organelles that contain a small, double-stranded, circular DNA molecule in eukaryotic cell. Mitochondria are also called "power-house of cell". It is site of cellular respiration in eukaryotic cell.

Question 9 : The correct option is Gregor Mendel; Pisum sativum.

Explanation : Gregor Mendel was the father of genetics and the first to study pea plants(Pisum sativum). He was also an Australian monk and a gardener. He worked in mid-1800s and contributed to our understanding of the particulate nature of inheritance as well as the basic genetic transmission patterns.

He discovered the basic laws of heredity while breeding pea plants. Three important laws proposed by Mendel to explain how traits inherited are : Law of Dominance, Law of Independent segregation and Law of independent assortment.

Mitochondria and chloroplasts are two types of organelles in eukaryotic cells. Current studies suggest that both organelles may have evolved by endosymbiosis of prokaryotes. Describe the functions of these two organelles and propose one structural evidence that strongly supports this endosymbiotic hypothesis.
