I'm thinking maybe C, but then, it could be one of the others too...

"A team of scientists visits an island in the Caribbean Sea. They find a diverse community of turtles, lizards, birds, and a variety of trees, shrubs, and grasses. No humans live on the island.

Several years later, the scientists return to the island. They find a much smaller community, with reduced populations of all of the species they had identified earlier. Some of the animals now appear to be absent from the island.

Which is the most likely explanation for the changes that the scientists observed?

A. Competition for resources caused all of the island populations to decrease at the same time.
B. A disease or parasite affected all of the island populations.
C. A natural disaster, such as a hurricane, struck the island.
D. Stress from overcrowding affected all of the island populations."

What type of lipids are found in all biological membranes?

Look at the following answer choices and determine which belongs in the both category. testable, can be disproven explains natural phenomena, has evidence to support it prediction, tentative, one or more scientists working together well established, many different scientists working independently, highly reliable

In a hypothetical breed of dogs, coat color is controlled by two genes. there are six different coat colors in this breed: black, brown, cream, gray, silver, and tan. consider the following crosses. cross 1: black females from a lineage of all black dogs are crossed with brown males from a lineage of all brown dogs. f1 males and females are all black. when f1 are intercrossed, f2 males and females are black or brown. cross 2: black females from a lineage of all black dogs are crossed with tan males from a lineage where all males are tan and all females are cream. f1 males are black, f1 females are gray. when f1 are intercrossed, f2 males and females are black, brown, gray, or tan. cross 3: silver females from a lineage where all females are silver and all males are gray are crossed with brown males from a lineage of all brown dogs. f1 males and females are all gray. when f1 are intercrossed, f2 males are black, brown, gray, or tan, f2 females are cream, gray, silver, or tan. select the correct statements regarding the mode of inheritance of the coat color genes. a) both genes are x-linked. b) both genes are autosomal. c) one of the genes modifies the expression of the other gene. d) each gene has an additive effect on the intensity of coat color. e) each gene independently specifies three colors. f) one of the genes is autosomal, and the other is x-linked.
