“Genes and environmental effects are often part of the explanation. “
“...disease-causing alleles of one gene may be suppressed by alleles of another gene elsewhere in the genome, or a person's overall health may influence the strength of a disease phenotype.”

Answer:
In explanation.
Explanation:
Effect of osmosis on cells:
-Osmosis is the movement of water across a cell membrane. Cells use osmosis to maintain concentration equilibrium (the concentrations of solute inside and outside the cell are equal). Changing the amount of water allows the cells to achieve equilibrium.
Effects of osmosis on tissues:
-Red blood cells placed in a solution with a higher water concentration compared to their contents (eg pure water) will gain water by osmosis, swell up, and burst. Water will diffuse from a higher water concentration outside the cell to a lower water concentration inside the cell.

Answer:
the humus contains the minerals necessary for chlorophyll synthesis
Explanation:
<em>The yellowness of leaves in plants can be attributed to inadequate chlorophyll in the plant</em>. The chlorophyll is responsible for the greenness appearance of the leaves of plants and when it is present in inadequate quantity, the leaves appear yellowish in color.
<u>Some of the minerals necessary for the formation of chlorophyll include magnesium, nitrogen, and iron</u>. It thus means that the humus supplied to the soil of group 1 plant has the necessary minerals to synthesize chlorophyll while the soil of group 2 plants is deficient in some or all the minerals required for chlorophyll synthesis.
Answer:
66.6% of the living progeny would be creepers
Explanation:
The creeper allele is Cr for both parents this means that there is a 50% chance that they will pass the C or r trait to their progeny. In this scenario the deleterious inheritance of rr will be 25% so this will not be factored in this answer. The other progeny is CC 25% and Cr 50% for genotype only
The new calculation for living progeny is this: Of the chances of three living progeny there could be one normal CC and two creepers Cr. This means that 33.3% of the living progeny is normal CC and 66.6% of the living progeny are creepers Cr.
