Answer:
The correct answer will be option-The red and white flower alleles are co dominant.
Explanation:
The Mendel suggested that for any trait, the organism contains its alleles which could be dominant and recessive. But there are cases in which multiple alleles exist for the same trait which are neither dominant nor recessive.
Two cases arise due to this in which both the dominant alleles co-exist and show their phenotype effect called "co-dominance" and when both alleles form a new phenotype called 'incomplete dominance".
In the given case, the self-pollination produces red, white and patched flowers as a result of co-dominance because both the alleles show the equal effect on the flower petals (mixed phenotype) and form a flower with red patches or spots on the flower.
Thus, the selected option is the correct answer.
Answer:
The presence of a larger proportion of unsaturated fatty acids in membranes imparts them fluidity at lower temperatures as required to maintain their normal functioning.
Explanation:
The proportion of unsaturated and saturated fatty acids in membranes regulates their fluidity. At lower temperatures, membranes become more rigid. To maintain their normal fluidity, the proportion of the unsaturated fatty acids in membranes is increased. The unsaturated fatty acids have double bonds in their hydrocarbon tails which in turn do not allow their tight packing and impart fluidity to the membrane core.
At higher temperatures, membranes become more fluid and therefore, the proportion of the unsaturated fatty acids is reduced. The tissues of reindeer at the body's extremities such as those near hooves are exposed to surroundings and thereby, lose heat and have lower temperatures. To maintain the fluidity of membranes, the cells of these tissues incorporate more of the unsaturated fatty acids in their membranes as compared to the tissues in the upper legs where the body temperature is relatively higher.
Biodegradability and what chemicals are produced when it is broken down.
Answer:
Water molecules tend to stick together due to the structure and charge of the atoms present in the water. Hydrogen atoms are positively charged while oxygen atoms are negatively charged. ... All water molecules are exerting cohesive forces on all the molecules around them including those on the surface of a body of water
