Biology
1 answer:
Mrac [35]3 years ago
5 0

Answer:

Yes, the environment and the heritage both plays very crucial role in defining the evolution. But how? let's start it here.

Explanation:

  • As per the Charles Darwin theory of natural selection, organisms that better adapt to changes can survive very well.
  • For example In earlier times, snakes used to have limbs but they are just useless for them and they are not using those limbs so in next generations snakes have vestigial remnants of limbs.
  • Another example we can study here is of mice, such as mice are nocturnal animals so they don't have vision capabilities and over generations they adapt a change due to their predatory nature and came with an affect of better hearing capabilities.

gogolik [260]

Answer:

To complete the question: a diploid organism has four pairs of chromosomes what proportion of gametes would be expected to contain some chromosomes from both parental and maternal origin? assume that there is no crossing over

Answer: 7/8

Explanation:

A diploid organism with four pairs of chromosomes...

Assume that the organism receives chromosomes A, B, C and D from the female parent and A', B', C' and D' from the male parent.

Proportion of gametes from patterns origin is the same as that of matters origin, this we have:

(1/2)^4 = 1/16 where 4 reps the number of possibilities, 1/2 rep the chance

Thus, the proportion of gametes expected to contain some chromosomes from both parental and maternal origin would be

(1 - (1/16 + 1/16)) = 14/16 = 7/8

because a monoglyceride molecule has more carbon atoms than a glucose molecule, you can assume that...
Alexxandr [17]

The monoglyceride molecule contain more energy than a glucose molecule because monoglyceride requires more oxygen for each carbon atom because there are more electrons surrounding each carbon in monoglyceride. Therefore, to oxidize monoglyceride more oxygen having high affinity for electrons, are required. Thus, monoglyceride produces more energy.
