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).
“Two species of crickets, Gryllus rubens and
Gryllus texensis, have different courtship songs which can be identified only
by the opposite sex of their own species” is an example of behavioral isolation.
Behavioral
isolation is an
important evolutionary mechanism that helps members of the same species
identify each other as proper mates.

A healthy lifestyle that includes adequate rest, exercise, and a balanced diet.
Type I is insulin-dependent; Type II is non-insulin-dependent. Type I requires injectable insulin to treat; Type II can be treated without insulin with correct diet and exercise. A person is usually born with Type I diabetes, whereas Type II has been linked to obesity and poor dietary habits.90 calories; one fat exchange = 45 calories.
Exchange lists can be used by diabetics to give freedom of choice in what they can have to eat or drink. It allows diabetics to select types and amounts of foods while maintaining a healthy calorie level.30 grams or 2 carbs, because two slices of bread 2 starch servings.
Carbohydrate counting can help people control their carbohydrate intake, which helps control blood sugar. It allows flexibility in menu planning because no food is excluded, and only carbohydrates are counted.
