The correct answer is that both the rabbit and coyote population could decrease because the original food supply decreased. We know that the initial crop increase caused the rabbit population to increase, which caused the coyote population to increase, so when the crops die there will not be enough food and the rabbits and coyotes will have to move on to another region to avoid starvation.
Answer:
There are different evidences for evolution that includes anatomy, fossils, molecular biology and biogeography.
Molecular biology uses DNA and protein sequences that the genetic code reflect the shared ancestry of life. DNA comparisons used for the anatomical evidence.
All living cells are organized in the same basic DNA and use the same genetic code. Proteins derived from genes, all originate from the same set of amino acids. Comparing parts of DNA in various species has shown that even very different organisms still have significant parts of similar DNA. For example, in chimpanzees and humans have some precent of same genetic structure. In the amino chain, chimpanzees and humans have only one position, while humans and moths have 31 different positions.
<u>There are different advantages and disadvatages of each type of evidences are:</u>
Advantages:
- Anatomy share information about the similar physical structures shared by common ancestor (homologous structures)
- Fossils provide information about the extinct species.
- Molecular biology provide genetical relationship between organisms.
- Biogeography share global organism distribution and island species unique characteristics reflect evolution and geologic change.
Disadvantages:
- some of the structures such as forelimbs of human and birds seems homologous in structure as per comparative anatomy but they have evolved independently in each species.
- Fossils are impressions of past living organism and buried in earth surface rom long geological past, hence during this geological time there can be many changes in the fossil structure and can manipulate the evidences.
- Molecular biology has disadvantage of lack of assay specificity and sensitivity.
- organism can evolve and adapt according to different condition, hence Biogeography can not exactly tell the exact changes in the characteristics of organisms on the basis of particular geology.
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: Disagree the tree is apart of the plant kingdom while the elephant and birds are in the animal kingdom
Answer:
This is not the best practice because the fever is a mechanism of the body against infection since it will raise the body temperature bacteria, which live well below 37 ° C, die, however it is noteworthy that by itself the fiber can not cure an infection but defenses are needed and must be treated with antibiotics.
In addition, in a small percentage of cases the fever becomes urgent. This is true. It is only true if it exceeds 42 ° C in a sustained manner.
