Answer:
Two adaptations of Darwin's Finches that helped them to survive are:
- Behavioral adaptations to use tools for foraging.
Explanation:
There are fourteen species of Darwin's finches that originated from a single species of ground dwelling seed eating finch.
These Finches occupied different niche in the Galapagos island and were widely studied by Darwin.
These finches are one of the best Examples of Adaptive radiation.
Studies state that during severe drought in Galapagos island most vegetation dried out and a few softer seeds were left.
These few seeds were quickly fed upon by the birds and only dry , hard seeds were left.
Only birds who had large and hard beaks could feed on these hard dry seeds.
To Ensure survival the Finches developed adaptations which resulted in hard and large beaks so that they can feed on those dried hard seed.
Some groups started feeding on insects and got their beaks adapted to capture and kill insects.
Second line of adaptation included changes in behaviour and cognitive intelligence where birds started using tools for foraging.
Answer:
Explanation:
Amount of water displaced by the sphere will be equal to the volume of complete sphere.
As the sphere completely sinks to the bottom of the cup.
We have been given;
Diameter of sphere (d) = 4.6 cm
So,
Volume of sphere (V):
By substituting value of r we get:
1 cm³ = 1 mL
V = 51 mL
So,
Water displaced by the sphere = 51 mL
I think b would fit more as the mitochondria, d would be the endoplasmic reticulum, and e would be lysosomes
Polypeptide chains undergo some modifications before they become fully functional. Some of these modifications include: proteolytic cleavage, lipidation and glycosylation. Proteolytic cleavage refers to the removal of some amino acids from a polypeptide chain by proteases in order for the protein to become active. An example of a substance that is modified through this process is insulin.
