Answer:

Explanation:

•Variation: Organism shows variation within a population, these variation could be body size, facial marks, hair color, number of offspring, etc. Also some features shows little or no variation, for example the number of eyes a vertebrate have, etc

•Inheritance: Certain traits are always passed from parents to their offsprings, these traits are called HERITABLE TRAITS. But traits that are exhibited as a result of an environment are termed weak heritable traits.

•High rate of population growth: When the number of offsprings produced in a year is greater than the resources within an environment, such population will experience high rate of mortality.

•Differential Survival and reproduction: The ability possessed by an individual to struggle for survival within it's environment will give rise to more offspring in the next generation.

If glucose is metabolized under completely anaerobic conditions, pyruvate ( Please explain why each answer is wrong or right.)
Nostrana [21]

Answer:

B.

Explanation:

A is wrong because pyruvate would enter the Krebs cycle under aerobic condition (when oxygen is present). Hence the name aerobic cellular respiration

C. I do not really too much about fructose or the concentration of oxygen, but I can assure that this answer choice is not correct.

D is wrong because NADH would be converted from NADP+. Either with oxidation or reduction, and this helps to keep this process going.

B is correct because fermentation is another word for anaerobic cellular respiration. The process takes place with the absence of oxygen. It either goes through Alcoholic or lactic acid fermentation.

I hope this helps!

A scientist is comparing the outer structure of an onion cell, structure X, to the outer structure of a human skin cell, structu
hammer [34]

Answer:

Structure X is only found in plant cells, and structure Y is found in plant and animal cells.  

Explanation:

The structure found on the outside of the onion cell is the cell wall, which is specific to plants. The structure found on the outside of the skin cell is the cell membrane, which is found on all cells.

Structure X is not living, and structure Y is living.  - this is false, both animal and plant cells are living.

Structure X can be found in some human cells, and structure Y can be found in some plant cells.  - this is false, the opposite is true.

Structure X is only found in plant cells, and structure Y is found in plant and animal cells.  - this is true structure X is the plant cell wall, and structure Y is the cell membrane

Structure X is semipermeable, and structure Y is selectively permeable. Semi-permeable and selectively permeable are essentially the same thing - it means the barrier allows some substances to pass through but not others.
