Marine iguanas are found only on the galapagos islands which biodiversity pattern does this represent? .
a. species vary globally .
b. species vary locally .
c. species vary over time .
d. species vary when isolated .

which of the following statements correctly defines evolution? .
a. evolution is the rate at which an individual organism changes .
b. evolution is the difference between animals in different places .
c. evolution is the comparison of fossils with living creatures.
d. evolution is the process through which species change over time .

The correct answer for the first question is-  A) species vary globally .

As per the information given in the question, Marine iguanas are found only on the galapagos islands. This indicates that throughout world, different species are found and some species are restricted to a particular area due to particular environmental conditions. Therefore, it can be said that species vary locally.

The correct answer for second question is- D). evolution is the process through which species change over time.

Evolution can be described as a process of change in the characteristics of organisms over many generations. It can be driven by various mechanisms such as natural selection, genetic drift.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

common management practices in dairy and poultry farming are: (i) proper shelter facilities and their regular cleaning. (ii) some basic hygienic conditions such as clean water, nutritious food, etc. (iii) animals are kept in spacious, airy, and ventilated place.
