Answer:
When certain large molecules are unable to move through the membrane without the help of channel proteins
Explanation:
Facilitated diffusion occurs when large molecules that are unable to pass through a membrane on their own make use of channel proteins to move from one side of the membrane to the other. Facilitated diffusion can occur when a liquid on one side of a membrane has a higher osmotic pressure than a liquid on the other side of the membrane, but it isn’t a required feature of facilitated diffusion. Similarly, facilitated diffusion can occur when there’s a large membrane potential present, but it isn’t a required feature of facilitated diffusion. Facilitated diffusion doesn’t require the use of energy, so the presence of ATP is irrelevant to facilitated diffusion occurring.
Answer:
The correct answer would be 32.
It can be calculated with the help of simple formula 2ⁿ
2ⁿ represents the possible number of combination of gametes produced by an organism.
n represents the haploid number of chromosome of an individual
Thus, the possible number of gametes produced by an organism with 5 chromosome pairs would be equal to 2⁵ = 2x2x2x2x2 = 32.
Red, i apologize but there’s no reasoning to my statement.
Answer:
2. comparative morphology
Explanation:
- Morphology is the study of the structure as well as the form of the organisms and studying their specific features.
- When the morphological characters of two or more different organisms are compared usually for the bass of taxonomical characterization then this is termed as comparative morphology.
- Using comparative morphology both similarities and differences in the anatomical structures of the organisms are observed.
- Using the comparative morphological studies one can see the common descent as well as the divergence of organisms.
- Therefore, Dr. Wilson is using comparative morphology to study similarities between the wing of a bat and the arm of a monkey.
