A.easier to condition
Explanation:
The dog may pant and pace when it's owner leaves the house, and over time, that dog may begin barking, destroying furniture and doorways or may vomit. The scientific term for what has happened those is sensitization.
1) Lysosomes, because they are the organelles that secrete these hydrolytic enzymes and help break down old organelles, viral/bacterial invaders, and food particles. For more information on cells please see the link in sources, it's a great slide show and can probably help you in the future too. Bookmark it!
<span>2) There are some really great sites explaining homeostasis and active transport below in the sources, some with animation that may make it a little easier for you to understand exactly what happens. </span>
<span>3) If you understand active transport first, the answer will actually be very easy. All you have to do is explain how active transport maintains homeostasis in the first place, then apply it to the specific situation of the fish. I honestly feel you need to answer this one yourself, since it is very clearly a question to test the comprehension of this material on your part; if you don't get it, you probably won't pass, and you'll be better off in the long run answering it yourself. </span>
<span>I hope the links help! And don't be afraid to use your book's index to find more information in chapters you haven't covered yet!</span>
Answer:
Charles Darwin was the man who came with the theory of natural selection. He witnessed finches within the Galapagos Islands and made notes on the similarities and differences of the finches across the group of islands. Each of the islands comprises finches, which were identical, however distinct in different ways.
Darwin found that the finches appeared to vary on the basis of the food sources available on each of the islands. If the prime food were seeds, the finches seemed to possess thicker beaks in order to break the seeds so that they can consume them.
On the other hand, if the prime food sources were insects, then the finches seemed to exhibit smaller and pointer beaks so that they could hold the insects readily. In this way, there is unity in diversity. All of these birds are finches and exhibited a common ancestor from which they have originated into the distinct species as mentioned.
Their variations lie in the habitats, in which they now inhabit. They had to amend with their environments in order to thrive, thus, offering diversity to unity.
