Ques:Q: All species have evolved a pattern of living, called a life history strategy, in which they partition energy for growth, maintenance, and what? Read this paragraph and choose the correct option from the provided answers: 45.2 Life Histories and Natural Selection All species have evolved a pattern of living, called a life history strategy, in which they partition energy for growth, maintenance, and reproduction. These patterns evolve through natural selection; they allow species to adapt to their environment to obtain the resources they need to successfully reproduce. There is an inverse relationship between fecundity and parental care. A species may reproduce early in life to ensure surviving to a reproductive age or reproduce later in life to become larger and healthier and better able to give parental care. A species may reproduce once (semelparity) or many times (iteroparity) in its life. Choices: - variation - abundance - deatn - reproduction A:

Ans:reproduction

Ques:Q: In chemical reactions, what substances can act like metals or nonmetals, depending on their number of electrons? Read this paragraph and choose the correct option from the provided answers: How metalloids behave in chemical interactions with other elements depends mainly on the number of electrons in the outer energy level of their atoms. Metalloids may act either like metals or nonmetals in chemical reactions. Choices: - diacritics - minerals - synthetics - metalloids A:

Ans:metalloids
