Answer:

d. secondary endosymbiosis.

Explanation:

  • When a living cell acquires another organism that eventually becomes a part of this cell, this process is known as primary endosymbiosis.
  • When an organism that has already undergone primary endosymbiosis engulfs another eukaryotic organism then this process is known as secondary endosymbiosis.
  • Secondary endosymbiosis has been known to occur in plastids because of which they are surrounded by two membranes. This bilayer is present because one of the layers is the original outer membrane of the organism and the other membrane is that of the organism that has been engulfed.

Why the number of male gametes are more than female gametes...pls give proper explanation
Alex787 [66]

Explanation:

The number of male gametes produced is way more than that of female gametes is because:

1. It will increase the probability of fertilization.

2. More male gametes means the chances of variations inoccurring offsprings are higher.

(Note: I just improved an answer of someone else because this question was asked before)

Question: "Give reason why Number of male gametes produced is much more than the female gametes produced?"

Explain if an unknown substance found on a meteorite is determined to contain no trace of carbon, can scientists conclude that t
Svetach [21]
All life as we know it is carbon-based, so what scientists could determine is that there is no carbon-based life at the origin of the meteorite. However, this does not necessarily mean that there is no life there; our knowledge is only based on our experiences of life on Earth, so it is possible that life has developed in other regions of space upon other elements and formations. For example, there could be life based on silicon or other chemical compositions.
