When Charles Darwin considered wings of birds, apart from his famous proposal he also predicted that fossils will be found with structures that are intermediate between early and modern form.
Answer: Option C
<u>Explanation:</u>
Charles Darwin was basically referring to transitional Fossil while considering Wings of bird. So what are transitional fossil? They are the fossil remains of both the ancestral group and the descendant group.
Since we don’t have enough record of the fossils, it is very difficult to know the accuracy of transitional fossil. However, we do have some record of fossils from which we can gather enough evidence of how the fossils where earlier and how it evolved over a period of time.
Answer:
Skeletal system
Explanation:
the bones of the skeleton protect the internal organs and reduce the risk of injury on impact. For example, the cranium protects the brain, the ribs offer protection to the heart and lungs, the vertebrae protect the spinal cord and the pelvis offers protection to the sensitive reproductive organs.
Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.
Answer:
A few obstacles would make it tough to accomplish this objective. In the first place, the polypeptide backbone is characteristically polar. Hardly any proteins would be dissolvable in a non-polar hydrocarbon. Moreover, to keep up the dissolvability of this protein, most of its amino acids would need to contain hydrophobic or non-polar R groups.
Then again, its charged or polar R groups would need to connect with one another or be covered in the core of the protein away from the hydrocarbon solvent. This would put noteworthy requirements on both the idea of the R groups and the structure of the protein that could take part in substrate recognition or catalysis. By and large, this is certainly not a reasonable objective.
