Answer:

Option D, Fossil in layer 6 are less than 540 million years old

Explanation:

In any fossil deposition, the youngest of fossils lies at the topmost layers while all other layers below it are much older than it.

Here, layer 1 lies at the bottom and layer 13 lies at the top. Thus, layer 1 is the oldest and layer 13 is the youngest fossil.

In the question , it is given that index fossil of age 540 million years old are found at the layer 5, therefore all layer lying above it will be less than 540 million years.

Therefore, option D is correct.

The neurons can be categorized on the basis of their functions into three types:  

1. Sensory neuron- The neuron which transmits the signals from the sense organs of the body to the central nervous system.

2. Interneurons- The neuron which connects the sensory neuron to the motor neuron by interpreting the signals from the sensory neurons.

Which stains are used to visualize structures in the membrane?
Rufina [12.5K]

Acid-fast and Gram is used to visualize the structures in a membrane.  

It is a differential staining procedure which is used to identify, <em>mycobacterium tuberculosis and M. leprae.</em>

Acid-fast bacteria are considered to be gram-positive in terms of their structure as, they contains peptidoglycan in its cell wall.

They stain poorly with Gram stain procedure, and appears as weak Gram-positive.

Membranes are consisted of lipid bilayer, which is doubled layer of phospholipid, glycolipid and cholesterol molecules, which contains the chains of fatty acids,  and

<em>determines weather a membrane is formed into long flat sheets or round vesicles.</em>

To examine the membrane protein structure, Electron microscopy technology is used and it enables the visualization of single protein at nanometers resolution.

Why was the advent of the amniotic egg so important in the evolution of terrestrial vertebrates?
Fynjy0 [20]

Explanation:

The evolution of egg was the most important evolutionary incident which allowed the evolution of the terrestrial animals. The amnion is the layer inside the chorion of the egg which keeps the embryo from drying out.

The formation of this layer completely removed the dependency of the organism to lay their eggs in the water to keep them wet.

This layer allowed the reptiles to lay their eggs on the land as the amnion can protect the embryo from drying out. The other layer of eggs protects the egg from the predators and the pathogens.

Thus, the evolution of the amniotic egg is very important from the evolutionary perspective.
