Answer:
Scientists called geochronologists are experts in dating rocks and fossils, and can often date fossils younger than around 50,000 years old using radiocarbon dating. This method has been used to provide dates for all kinds of interesting material like cave rock art and fossilized poop
A potometer can be used to measure the rate of transpiration that's proportional to water uptake. Transpiration cannot be measured directly as some of the water will be used in photosynthesis.
Answer:
The central dogma of the molecular biology explains the flow of information from the replication of the DNA to the expression of proteins. This central dogma must be error free so that correct information can be transferred. The error in this process can cause life threatening situation. So, the phases of proof reading and rectification is required in this process.
From the DNA replication to the transcription of the RNA and final translation into the proteins requires proof reading mechanisms and many enzymes with the non enzymatic processes. The enzymes of transcription, replication and translation shows high degree of proof reading and works in efficient way. The incorporation of the amino acids, post translation modification makes the information flow as correct as possible.
Hi, In my opinion, bat will be the most closely related to hawk.
Why?
This is because, when we consider the photo of a bat and a hawk, we notice the similarities like:-
• Wings- They have nearly the same short wings decreasing the area of contact with air and enabling higher flight area.
• Presence of small snouted beak-like structure and presence of less or more similar color.
• Both live in trees and are normally not companiable with humans.
• Hawks and bats are both having a similar anatomy, not body, I meant that they have similar positioning of organs like stomach, pancreas etc.
• They have the sense of locating prey miles away, enabling easier locating of food.
Hope this helps...

Answer:
Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.
Explanation:
Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.
Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.
