Answer:
1. Endocrine disrupters
Explanation:
Endocrine disrupters are chemicals that alters or interrupts the normal functioning of the endocrine system that consists of several glands that produce hormones responsible for various functions such as metabolism, reproduction, growth, etc. When this interferes with the endocrine system, it can bring about many undesirable consequences, one of which is low testosterone levels as reported in the Alligators in Florida lake that is polluted by high levels of dioxins. These chemicals act as endocrine disrupters.

Answer:
Type I curve
Explanation:
The K-strategist are species characterized by relatively stable populations that fluctuate at the carrying capacity of the habitat or niche in which organisms reside. Elephants are considered as K-strategists because they have a low population growth rate and relatively stable populations. There are three different types of survivorship curves. The Type I curve (also referred to as A curve) is characteristic of k-strategist organisms. Humans and elephants exhibit a Type I survivorship curve in which organisms tend to die when they become elderly. These species have a small number of offspring and provide parental care to ensure their survival. In a Type II survivorship curve, species produce many offspring and only some offspring survive (e.g., birds), while in Type III survivorship curve organisms produce many more offspring and most do not survive (i.e., r-strategists such as frogs or insects).
