Answer:
To find the extinct species and their divergence of characters can be studied using molecular genetic techniques.
Explanation:
- Paleontology is the study of ancient species and their remaining that were found millions of years ago. These species extinction can be found and manipulated to find out the origin or divergence of species from their origin
- The samples of these species may contains their remains that help the biologist to isolate and analyze their protein or DNA. when the DNA is isolated their sequences can be generated using molecular biology techniques.
- When the sequences are identified by advanced molecular biology techniques, the existence and similarities of different species due to their convergence or divergence can be identified.
- By identifying the convergence or divergence the characteristics, evolutionary change in behavior, variation in appearance can be studied.
- By using these techniques, biologist have found that <em>homo sapiens</em> are 99% have their similarities with chimpanzee
- Thus, using genetics in paleontology helps us to understand adaptation a species is changing according to the evolutionary changes.
Answer:
False.
Explanation:
Cell membrane is made of the lipids and proteins with the attached moieties of carbohydrates. The plasma membrane is the selectively permeable membrane that allows the diffusion of some selected particles only.
The transport along the cell membrane depends on the size and the hydrophobicity of the molecule. The size of oxygen is although higher than magnesium but to its highly hydrophobic nature it can easily pass through the plasma membrane as compared with the magnesium. The oxygen diffuses out faster than magnesium.
Thus, the answer is false.
Answer:
Relative age only tells us the order in which events occurred, from the earliest to the most recent. Knowing the actual date of an event allows us to say exactly how old something is or how long ago it actually took place.
Explanation:
Answer:
1.Collect a thin slice of your sample and place it on a clean, dry slide 2.Place one drop of water over your sample 3. Place the coverslip at a 45-degree angle with one edge touching the water and let go 4. Your slide is ready to be viewed.
