Answer:
1. Watch Mark Rober...He's great!
2. A shark maintains his buoyancy because a shark was the same amount of force pushing awards as gravity is pulling is downwards. So instead of sinking it floats. I know that didn't make a lot of sense but seriously, watch Mark Rober and you will know everything!!! (unlike me, a freshman)
3. P.S. If you want to learn more about buoyancy, I suggest you watch the balls in the liquid sand video
Explanation:
Copyright is a thing saying that you can copy it but you have to get permission. It is important because otherwise people can just steal credit and get glory while basically doing nothing.
Answer:
8 different combinations of gametes can be produced by this mosquito, assuming no homologous recombination between chromosomes
Explanation:
The mosquito has 6 chromosomes. This means that means it has 3 pairs of homologous chromosomes. Basically, we can assume the number of different gametes by 2 to the power of 3 as their are 3 homologous pairs. This means 2×2×2 which will be equal to the amount of eight. Hence, eight different combination of gametes will be produced.
Answer:
A) Phanerozoic
Explanation:
In the given question, the chart about the evolution of insects has not been provided but based on the previous knowledge, this question can be answered.
The geologists have divided the time scale into many variables in which Eon represent the longest time scale period which has lasted for the millions of year.
The Phanerozoic eon represents the time scale during which first visible life evolved and began around 542 million years ago and is present until today. The insects belong to the arthropod group which evolved during a smaller time scale called Devonian period.
Since the insects evolved around 479 million years ago which falls under the Phanerozoic eon, therefore, phanerozoic is the correct answer.
Thus, Option-A is correct.
