Answer:
The correct answer would be b. Their cells are small and lack a nucleus.
Both archaea and bacteria are prokaryotic organisms that is, they both are devoid of a nucleus and other membrane-bound organelles such as mitochondria, chloroplast et cetera.
They also share a similarity in terms of shape and size of the cells. Both of them are unicellular in nature and can not be seen by naked eyes.
They show variations in their genetic and biochemical ways. For example, archae contains three RNA polymerases whereas bacteria contain a single RNA polymerase.
Their cell wall also show variation in composition. For example, a bacterial cell wall contains peptidoglycans, whereas archae cell wall does not.
Thus, we can say that archae and bacteria are similar in a manner that their cells are small and lack a nucleus.
The correct answer is (C) :))
The plane that divides the body into left and right portions
is known as the sagittal plane also known as the median plane. Sagittal plane
bisects the body into two halves and the plane motion occurs around a coronal
axis. Movements in the sagittal plane are the flexion and the extension. The Flexion
movement involves the bending movement in which the relative angle between two
adjacent segments decreases. The Extension movement involves a straightening
movement in which the relative angle between the two adjacent segments
increases. In general, both flexion and extension movement occur in many joints
in the body, which include shoulder, wrist, vertebral, elbow, knee, foot, hand
and hip.
The sagittal plane has two subsections; they are the
Midsagittal and the Parasagittal. The midsagittal runs through the median plane
and divides along the line of symmetry while the parasagittal plane is parallel
to the mid-line and divides the body into two unequal halves.
