Answer:
One of the probable ways to determine how long ago any two species of bacteria diverged from each other is by drawing a phylogenetic tree.
Explanation:
- Phylogenetic tree are trees that show the ancestry of two species of interest and the relationship between them.
- The idea behind the construction of phylogenetic tree is darwins's "descent with modification theory".
- A phylogenetic tree is constructed using the similarities or differences in either physical characteristics, behavorial, or genetic buildup.
- Derived traits shared between the different species are the actual data used to construct a phylogenetic tree.
The right answer is B.
Mutations are not always unfavorable, they are often "indifferent" as to the survival of the cells or the individual.
Mutations are the primary source of variation in the genetic material underlying the evolution of living things. They can have a beneficial effect for the species.
The balanced equation is
<span>8SO2 + 16H2S ----> 3S8 + 16H2O
</span>so
77g SO2 / 64g/mole = 1.203moles of SO2
<span>77g H2S / 34g/mole = 2.26moles of H2S
</span>now
<span>1.203 moles SO2 yields 3/8x amount that is = 0.456moles of S8
</span>so
<span>2.06moles H2S yields 3/16x amount = 0.386moles of S8
</span>hence
H2S = produce only 0.386moles of S8 = 98.98g S8

Red blood cells carry oxygen to the body, the reason for this is because; red blood cells<span> contain haemoglobin, which absorbs </span>oxygen<span> in the lungs and releases </span>oxygen<span> in the rest of the </span>body<span>.

Answer:
it is always deadly
Explanation:
It is because when mutation occurs dna gene is changed or damaged
