Question 2 of 10
Which of the following should be included in a good conclusion?

Answers

Answer:

How to write a conclusion

An effective conclusion is created by following these steps:

Restate the thesis: An effective conclusion brings the reader back to the main point, reminding the reader of the purpose of the essay. However, avoid repeating the thesis verbatim. Paraphrase your argument slightly while still preserving the primary point.

Reiterate your supporting points: Aside from restating your thesis, you should also reiterate the points that you made to support it throughout the paper. But instead of simply repeating the paper's arguments, summarize the ideas.

Make a connection between your opening and closing statements: It's often effective to return to the introduction's themes, giving the reader a strong sense of conclusion. You can accomplish this by using similar concepts, returning to an original scenario or by including the same imagery.

Provide some insight: Your conclusion should leave the reader with a solution, an insight, questions for further study or a call to action. What are the implications of your argument? Why should anyone care? You'll want to answer these types of questions here and leave your audience with something to think about.

When you breathe, the pressure inside the lungs is different than the pressure outside the lungs. This is an example of a(n) __________. concentration gradient pressure gradient electrical gradient temperature gradient

Answers

Answer:

pressure gradient

Explanation:

The correct answer would be pressure gradient.

A pressure gradient is created when there is a difference in the amount of pressure between two points or locations that are adjacent to one another.

In this case, the two locations that are adjacent to one another are the inside and outside of the lung. When one breathes in, the pressure inside the lung is more than that of the outside and the lung expands as a result. When we breathe out, the pressure outside is more than that of the inside and the lung collapses.

Explanation:

Species that compete for the same resources often switch to either use different resources or find ways to reduce competition. Why is this often true

Answers

Answer:

The correct answer is - to increase their survivability and reproductivity in the species.

Explanation:

Competition is the result of an interaction between two or more species or populations where both need or depends on the same limited resources that is utilized and protected by both and due to this one individual reduces the survival or reproduction of another individual.

In order to survive and reproduce their numbers species have to find other resources to feed or utilize or have to find new ways as if they did not adapt as per the changes they will be left very few or extinct.

A diagram shows a potato producing new tubers. Buds on the parent plant grow into stems that grow downwards called stolons. The end of each stolon develop in to new tuber.

1) Give two pieces of evidence which show that this is an asexual method of reproduction.

2) Explain why all the new tubers will be genetically identical.

​

Answers

Answer/Explanation:

Asexual reproduction is a type of reproduction in which new organisms that are identical are formed form a parent without the fusion of male and female gametes and do not require fertilization. Offspring formed are usually identical genetically, and are referred to as clones of the parent. Usually, only one parent is involved.

1. Two pieces of evidence that shows the potato growing is an asexual method of reproduction are:

i. Only one parent is involved

ii. The new tubers are identical (clones of the parent)

2. Reasons Why the new tubers will be genetically identical:

i. They grow from 1 parent by asexual reproduction

ii. No mixing of male and female gametes, so no exchange of genes takes place

Answers

Answer:

- An element is a pure substance that cannot be broken down into a simpler form.

- All elements are listed on the periodic table of elements.

- An element symbol begins with a capital letter; if there is a second or even third letter, it is a lowercase letter

Explanation:

An element is one of the two types of pure substances i.e. substances that cannot be broken down into simpler forms. Elements are made up of only one type of atom e.g. Fe, Cl2 (two chlorine atoms).

All known or discovered chemical elements are represented on the periodic table. In an order of increasing atomic number, elements are arranged from left to right on the periodic table.

The symbol of an element begins with a first letter written in capital letters while the subsequent letters can be written in lower cases. For example, Fe, Cu, Hg, Zn etc.
