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).
Answer:
As the outer layer of your skin separates your body from its environment, the cell membrane (also known as the plasma membrane) separates the inner contents of a cell from its exterior environment. This cell membrane provides a protective barrier around the cell and regulates which materials can pass in or out.
Explanation:
Answer:
option C. permissive stimuli
Explanation:
The three major kinds of stimulus that triggers the endocrine glands to synthesize and release hormones are humoral stimuli, hormonal stimuli and neural stimuli. The humoral stimulus regulates the release of hormones with the changes in the concentration of extracellular fluids. For example, the increase of glucose concentration in blood causes pancreas to release hormone insulin.
The hormonal stimuli allows secretion of hormone only with the secretion of any other hormone. The hypothalamus gland secretions allows the anterior pituitary gland to secrete hormones. The release of thyroid hormone is an example of hormonal stimuli.
The neural stimuli allows the production of hormones directly from the glands. The production of epinephrine and norepinephrine hormones are the example of neural stimuli. Thus, option C is correct.
