Graph A: A uniform density curve is at y = one-fourth from negative 1 to 3. Graph B: A line goes from (negative 1, 0) to (0, one-third), is horizontal to (2, one-third), and then decreases to (3, 0). Which graph represents a density curve, and why? graph A only, because the curve is above the horizontal axis, and the area under the curve is 1 graph B only, because the curve is above the horizontal axis, and the area under the curve is 1 both graph A and graph B, because both curves are above the horizontal axis, and the areas under both curves equal 1 neither graph A nor graph B, because, even though both curves are above the horizontal axis, the area cannot be determined for graph B

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

the most boring thing ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.
