why would shuffling genetic material to produce new combinations of characteristics be advantageous to a species?
Radda [10]

Answer:

Suffling of genetic material increases genetic variation in offspring which is important for evolution.

Explanation:

Genetic shuffling or genetic recombination helps in the formation of new trait combinations which increase the genetic variation in the population and this genetic variation is very much important for the evolution of species.

In sexual reproduction, the genetic shuffling occurs during the formation of gametes when the two homologous chromosomes exchange their genetic material with each other. This increase variation in gametes.

Fusion of two different gametes in sexual reproduction also helps in increasing the genetic variation in the offspring.

how lysosomes may be involved in the removal of the interdigital membrane of the developing mammalian fetus
Mars2501 [29]

Answer:

Lysosomes have the function of digesting substances, this function allows it to be involved in the removal of the interdigital membrane of the developing mammal fetus.

Explanation:

Lysosomes are organelles formed by numerous digestive enzymes. These enzymes allow lysosomes to be able to digest substances and even cellular apparatus, when needed.

The digestive function of lysosomes can be observed in the removal of the interdigital membrane of the developing mammalian fetus, by the action of digestive enzymes that have the ability to remove this entire membrane and any other undesirable tissue for the next stages of development of the fetus.

Verizon [17]

Answer:

Net photosynthesis- 3mm/20min- 1.5mm/10min

Cellular respiration- 1mm/15min- 0.66mm/10min

Gross photosynthesis = Net photosynthesis + Cellular respiration = 1.5+0.66 = 2.16 (mm/10min)

Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr

As we are measuring rate of photosynthesis in hr ,we should multiply gross photosynthesis with 6 (as we measured gross photosynthesis for 10 min).
