How does the sea ice in 2019 compare to the sea ice in 2012 during April?

Katarina [22]

The total amount of sea ice showed a decline from 2012 to 2019. The correct option would be D.

<h3>Graphical illustration</h3>

Looking at the graph, from February to June 2012, there is a decline in the amount of sea ice.

A similar decline in the amount of sea ice can be observed in the year 2019.

However, the sea ice levels for the various months in 2012 remain generally above the sea ice levels in the various months in 2019.

Thus, overall, one can say there is a general decline in the ice level from 2012 to 2019.

What are some outcomes of nuclear fusion?

Svetlanka [38]

Answer:

A. produce larger materials from the collision of smaller materials

Explanation:

The outcome of nuclear fusion reaction is that it produces larger materials from the collision of smaller materials.

Nuclear fusion is the combination of small atomic nuclei into larger ones with the release of a large amount of energy.
The energy released provides the needed temperature for another set of atoms to fuse.
This process in turn yields a bulkier material accompanied with the release of a lot of energy.

bezimeni [28]

Insect herbivory is likely to affect the competitive relationship between the species in that a plant affected by these insects will have a hard time competing with those who are unbothered by the insects.

<em>Although I could not locate the Graph or options for this question online, I can offer a general assessment to help you answer the question.</em>

<em />

<em />

Insect herbivory is when insects consume plants or parts of a plant as their main food source. Interestingly, this term also applies to those insects who do not harm the plant, but consume the pollen, etc.

However, focusing on harmful insect herbivory, we can assume that in the presence of these insects a plant will have a hard time staying alive or mating effectively due to the damage caused. Therefore, we can assume that <u>the </u><u>plant </u><u>on the </u><u>left </u><u>will not be able to stay </u><u>competitive</u>.
