Answer:
Brown dwarfs are objects which are too large to be called planets and too small to be stars. They have masses that range between twice the mass of Jupiter and the lower mass limit for nuclear reactions (0.08 times the mass of our sun). ... Brown dwarfs are very dim and cool compared with stars.
Explanation:
Answer:
the time that cell spend in prophase is 30 minutes
Explanation:
The computation is shown below:
= Number of cell ÷ sample
= 25 ÷ 100
= 1 ÷ 4
Now it takes two hours
So,
= 1 ÷ 4 × 2 hours
= 0.5
This 0.5 represent the 30 minutes
Hence, the time that cell spend in prophase is 30 minutes
No they don’t, but to be able to have cellular respiration it can perform aerobic cellular respiration. These cells will move electrons back and forth across their cell membrane. Other types of prokaryotes cannot use oxygen to perform cellular respiration, so they perform anaerobic respiration.
Answer:

<span>When traveling in a vacuum, electronic waves from the electromagnetic spectrum all travel at the same speed. Velocity is speed with direction, so they would all travel at the same velocity, realtively speaking. But frequency and wavelength are quite different</span>
