<h2>B) is the correct option </h2>
Explanation:
- Collagen is a hard, insoluble, and fibrous protein that makes up one-third of the protein in the human body
- Molecules in collagen are packed together to form long and thin fibrils
- These act as supporting structures and anchor cells to each other and also give the skin strength and elasticity
- Collagen is the most abundant protein found in bones, tendons and muscle skin
- Collagen forms a scaffold to provide strength and structure
Because of these characteristics, genes associated with collagen is the best choice to base the phylogeny, rest all other options are not much diverse and specific to particular group of animal kingdom

Hope it helps
Explanation:
The oncotic pressure inside the cell will be greater than the pressure outside. Thus causing the cell membrane to rupture. If red blood cells are placed in pure water, water enters into the red blood cells by osmosis and the red blood cells swell up and burst while the onion cells would absorb water due to osmosis, swell and become turgid.The cell sap move conc. than surrounding water gate into the cell by osmosis; the cell swells/becomes turgid; but does not burst due to the cell wall.
Answer:
3.9 billion years
Explanation:
The half-life of potassium-40 is the time it takes for half of it to decay.
After one half-life, half of the original amount will remain.
After a second half-life, half of that amount will remain, and so on.
We can construct a table as follows:

We see that the mass will drop to 10 g after three half-lives.
1 half-life = 1.3 billion years
3 half-lives = 3.9 billion years
