Gravity , Explosion
<u>Explanation:</u>
Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger.
Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star.
Answer:
Yes.
Probability of such child = 1/2 or 50%
Explanation:
According to the question, below are the genotypes and phenotypes possibilities:
aa = normal vision & no headache
Aa = normal vision & no headache
AA = blindness & headache
Male Female
Aa aa
Possible genotypes of progeny: Aa Aa aa aa
So it is clear that out of the 4 probable children, 2 with 'genotype aa' will have normal vision & no headache.
Mathematical expression is as under:
2/4 = 1/2 that means 50% progeny.
Answer:
I think stream bank. It grows in moist places and wetlands, and is especially abundant along streamsides and riparian areas at elevations below 1400 m.
Explanation:
Base of the substitution of the codon or frameshift mutation
Answer:
The type of biodiversity been practiced is REFORESTATION .
Explanation:
Reforestation is the deliberate or natural process by which destroyed plants are re-planted in a particular forest. Deforestation usually brings about destruction of different plants species and this normally throws the ecosystem out of balance. The negative process can be reversed by mean of reforestation, in which new plants are planted in the place of the destroyed ones.
