Is there a solution for the impacts overfishing?

Answers

Answer:

The world’s oceans are so big we thought for a long time that there was nothing humans could do to hurt them. Now we’re facing an imminent and global collapse of our fisheries, projected to happen as early as 2048, thanks to overfishing, wasteful fishing practices and massive overconsumption. But, there are a few key tried-and-tested solutions to overfishing that have been successfully implemented around the world. The trick is to scale these solutions up to a global scale, encouraging countries that have originally been resistant to helping and get them onboard, and supporting countries that don’t have the means to update their fishing policies themselves.

Please can someone explain the differences in variables (e.g. control variable, Independent variable and Dependent variable). I know the definition, but I'm still not sure which is which when undertaking an experiment. Could someone possibly give me an example of an experiment and which is which?

Answers

Answer:

Independent Variable: The thing in an experiment which is changed.

Dependent Variable: The thing in an experiment which is affected by the change. (In other words, it's affected by the independent variable.)

Control Variable: The other factors of the experiment that remain unchanged.

For example, say you want to do an experiment about the effects of water on plant height. So, the independent variable, or the thing that is changed would be the amount of water, and the dependent variable would be the plant height, as the plant height is directly affected by the independent variable. Lastly, for this to be a fair experiment, there must be control variables. For example, all of the plants should be put in a room with equal temperature, they should get the same amount of sunlight, etc.

I hope this answers your question- feel free to ask me if you need any more help.

Answer with Explanation:

Lol.. even i was confused before  .. so i learnt now ill help u :

Simple!

See... lets take simple expirament to explain:

My expirament is to verify if sunlight affects the growth of plants ...

So here :

My controlled variable : It is what is held constant.. So ur supposed to NOT it like everything else expect sunlight..(ex: water, soil, type of plant etc)

My Independent variable : Variable that is changed.... So this is wht  u ARE changing to make th expirament ... (for ex: here sunlight u will chanhe... u will put on in a dark room and a nother in the light..)  

My dependetn variabe:l Some thing that changes on is own..cause of the expiramen t... like the result ..(for ex: height , growth of plant etc)

I hope u  understood !!  :))

Chlorine has 7 valence electrons. With what group of elements will chlorine most readily bond?

Group 1
Group 2
Group 16
Group 18

Answers

Answer:

group 1

Explanation:

chlorine donate electron

Chlorine will more likely to form bonds with the elements of group 1 as it has 7 valence electrons.

Chlorine element:

Chlorine is an element that is present in group 17. This family is also known as the Halogen family. The elements of this group will have seven electrons in their outermost shell. It has only one electron less to attain a stable noble electron configuration.

Thus, it will form bond more readily with Group 1 that has only one electron in its outermost shell.

Thus, correct option is a.

Glucose in an energy molecule contained in carbohydrate food substances. The end product of the digestion of carbohydrate is glucose which is broken down to produce energy.

The sequence of breakdown of glucose is as follows; In the first step, 6-carbon glucose is broken down into two molecules of  3-carbon pyruvic acid. This occurs in the cytoplasm of the cell. It is an anaerobic process.

In the second step which occurs in the mitochondrion, each of the molecules of pyruvic acid is now oxidized to carbon dioxide and water and energy is produced in the process.
