The body needs energy to excerices
Answer:
third law states every action has equal and opposite reaction
Explanation:
so the answer is D
Answer:
Option A, Neither the researchers nor the study participants know who is receiving the drug and who is receiving the placebo.
Explanation:
In a double blind test, both the researcher and research participants are unaware of the exercise in a medical test . During the research active medication is given to some of the research participants making sure that researcher is unaware of that while observing all the participants. However, at the end of the experiment ,both the researcher and research participants get to know who has received the treatment.
Hence, option A is correct
The interaction between red-billed oxpecker and impala is mutualism. The interaction between titan triggerfish and smaller fishes is commensalism.
<h3>Mutualism and Commensalism</h3>
Mutualism is a form of symbiotic interaction between two organisms in which both organisms benefit from the interaction without being negatively affected in any way.
Commensalism, on the other hand, is a form of interaction between two organisms in which one (the commensal) gains and the other neither benefits nor lose from the interaction.
The red-billed oxpecker gets its food off the fur of the Impala. The tick that serves as food for red-billed oxpecker is a parasite that harms the impala. Thus, the red-billed oxpecker gets its food while the impala gets the ticks that can harm it removed. A mutually beneficial relationship.
The activities of the Titan triggerfish benefit smaller fishes. The Titan triggerfish neither benefits nor gets harmed in the interaction. A form of commensalism.

Answer:
llbb
Explanation:
<em>The genotype of the black, short-haired otter could be determined by testing-crossing with a brown, long-haired otter whose genotype would be </em><em>llbb</em><em>.</em>
Analysis of the resulting zygote from the cross would give an indication of the genotype of the otter - whether it has two dominant alleles each for the black, short-hair traits or heterozygous.
<u>If the otter has two dominant alleles for the two traits, all the resulting zygote from the test-cross would have black, short-hair, but if it is heterozygous, a mixed phenotype set of zygote would be obtained.</u>
