Answer:
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. Explanation: The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism, trophically transmitted parasitism, vector-transmitted parasitism, parasitoidism, and micropredation.
Half of the guinea pigs will have black fur, while the other half will have white fur. This is because the black is dominant, masking the white gene. But when both genes are recessive, the offspring will have white fur.
Answer: Option (c) is the correct answer.
Explanation:
A long hydrocarbon chain that consists a terminal carboxylic group is known as a fatty acid.
An unsaturated fatty acid consists a double bond within the fatty acid chain. If a fatty acid contains more than one double bond then it is known as polyunsaturated fatty acid.
For example, oelic acid has chemical formula 
is an unsaturated fatty acid.
Therefore, we can conclude that option (c) represents an unsaturated fatty acid.
Answer:
The correct answer is - accurate.
Explanation:
Systematic measurement errors take place when there is a consistent inaccuracy found in the result of the measurement. In the given case here is consistent 10 points lower than the actual value of hormones produced in the mice. the tool that is measuring the level of the hormones in the mice is showing systematic error and measurements are not accurate.
Thus, the correct answer is - accurate.
