The correct answer is extinction-adaptive characteristics of a species are not adequate. Extinction is an evolutionary term referring to the termination of a species because they are no longer able to survive under the conditions of their environment.
Natural selection is wrongly explained here since it is the evolutionary mechanism according to which the fittest organisms survive.
Gene recombination is also wrongly explained. It is the exchange of genetic material between different chromosomes or different parts of the same chromosome.
Mutation is also wrongly explained since it is a permanent change in the nucleotide sequence of the genome.
I’m so sorry they did this one of mine tried to make this one too
Answer:
Endothermic reaction
Explanation:
An endothermic reaction is that reaction that involves the absorption or use of energy in order to occur. That is, endothermic reactions are energy-consuming. On the contrary, an exothermic reaction releases energy into the surrounding environment.
Breaking a chemical bond requires energy, hence, it is an endothermic process while forming a bond releases energy, hence, an exothermic process. Since a chemical reaction involves breaking and forming bonds, the reaction is overally termed endothermic or exothermic depending on whether more energy is used or released respectively.
In this question, a substance is broken down into its atomic particles when it dissolves in water. In order to break this substance down into atom, the bonds holding each molecule must be broken, hence, energy will be utilized making this an ENDOTHERMIC REACTION.
Absolute dating deals with age of rock and relative dating deals with age of fossils.
Explanation:
Absolute age is mainly used to measure the actual age of an object. Relative age is mainly used to determine the age of an object related to other objects.
Absolute age is exact in nature but in the other case relative age is estimated in nature.
To determining age of fossils relative dating is used but in the other hand while determining age of rocks absolute dating is used.
Example in case of absolute age if somebody says she has a younger brother who is 2 years old and elder brother who is 12 years old she is specifically mentioning the age whereas in relative age no age will be specifically mentioned.
The correct answer is B. Find the relative age of one rock layer at the giving location.
