I’d go with B. (if it’s not then C)
Your answer to your Question is ...A: deep
These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them. Occasional events also trigger serious currents.
B. plastic , the recycling of plastic would conserve fossil fuels
The correct answer is D. House cats, lions, and tigers belong to the same class and family.
Explanation:
Taxonomy classifies animals using different levels such as kingdom, family, order, species, etc. that show the features of the organism and its relationship or similarities with others. In the chart presented, the only level that is different for the three animals is the last one, which is the species level because in this the cat is classified as Domesticus, the lion as Leo, and the tiger as Tigris. This implies the other levels including the class (Mammalia or mammal) or family (Felidae) is the name of the three animals. This makes the last answer correct and shows these three animals are closely related.
I think the correct answer would be C. It would be restricting water and/or nutrients, instead of supplying ample quantities of both that would not change the results of the experiment. This is because you are still supplying the same amount of nutrients and other things needed by the plant so the ratio of the growth of the plants will still be the same.
