Answer:
B
Explanation:
According to Mendel, an organism receives two forms of a gene from each parent. This form received by each parent is called an ALLELE. An allele is the variant form of a gene for a particular trait.
For a diploid organism, two copies of genes (alleles) are acquired by an organism. The combination of these alleles from each parent determines the genotype for that gene.
In Mendel's experiments, he discovered that one allele can mask the expression of another for a trait. He called the allele that masks DOMINANT allele while the allele that is masked RECESSIVE allele. The combination of these alleles, whether two dominant or two recessive called HOMOZYGOUS or one dominant and one recessive called HETEROZYGOUS, determines the phenotype of the organism for that gene.
N.B: There are exceptions to this pattern of inheritance.
Answer:
An ore is mined so that Metals can be removed from it.
Explanation:
An ore is ought to be mined so that it can be refined, the waste elements are removed from it, and the valuable elements, such as metals are kept.
Ores if not mined are of no use they are a pile of dirt until processed and therefore, to bring out the real value of an ore, it has to be mined and processed
Given,
3ml = 1 drop
1 ml = 1/3 drop
1000ml = 1x1000/3 drops
1 Litre = 1000/3 drop
1 drop = 3/1000 litre
1 drop = 0.003 litre
Hence, the correct answer is option B.
The levels of energy are the sun that our main energy source
