It comes from a unicellular organism named Chloroplast that produces a green pigment substance called chlorophyll, this where oxygen is produced as a by-product of photosynthesis.
Answer:
from the image:
1. eight
2. four
3. less than
Explanation:
from the data given...
n= 4
where n= # of genes
&, the extreme # of segments= 
Genes, which make up a genotype are instructions for encoding a phenotype, expressed as proteins in translation.
...one gene may have 2 alleles
An allele is an alternate form of a particular gene. Genes can have multiple alleles, but in this case...
∴4 genes= 4 × 2=<u> </u><u>8 segments</u>
<u />
<u>Thus, each allele gives </u> 
= <u>1 segment</u>

1. Metals are the best conductors because their electrons run freely (Copper, gold, silver...) .
2. Nonmetals are insulators because they have a tight hold on their electrons (Glass, plastic, wood...).
a. redwood trees. K-selected species are living organisms that tend to be larger than those in the r-selected species. They also have relatively stable population and live longer, but produce relatively fewer number of offspring. Redwood trees are the biggest and tallest trees in the planet; they can live up to a thousand years.
Mutation, recombination and immigration of genes
