Answer:
An association between two organisms in which one benefits and the other derives neither benefit nor harm.
Explanation:
5 is C -- mutation.
I can't read all of 6-- sorry!
Answer:
(i) An allele is a variant of a gene, can either be short or tall.
Dominant = the tall allele that "trumps" the short allele. if a dominant and recessive allele is present (heterozygous) then the dominant phenotype will be shown.
(ii) David's eyes are Brown
(iii) Sarah's eyes are blue
(iv) David - B, b
Sarah - b, b
(v) Possible genotypes include Bb and bb. These give the phenotypes of brown eyes or blue eyes.
(vi) The chance for blue eyes is 50% (or 1:1 ratio)
Answer:
From factory emissions to carbon dioxide in the atmosphere (C)
The process occurring can be called Combustion. In this process, organic matter is burned in the presence of oxygen (oxidizer). It releases energy and carbon dioxide because the carbon in organic matter is oxidized to form CO2.
from dead organisms to fossils and fossil fuels (E)
The process explained in the question can be stated as Fossilisation. In this process, dead remains of plants and animals are transformed into fossils under pressure. The organic matter is preserved according to the shape of the organism.
from factory emissions to carbon dioxide in the atmosphere (C) & from carbon dioxide in the atmosphere to photosynthesis (B)
Two reactions represent the conversation of mass and energy. The burning of fossil fuel (mass) releases energy and carbon dioxide, which is again used by plants to store energy in the process of photosynthesis. This is shown in C and B part of the figure
