Answer:
A
Explanation:
The number of different species in a particular habitat is what is what makes up the biodiversity in such habitat. The more varied the species are, the higher the biodiversity.
There are factors that could lead to a decline in the biodiversity level of an habitat which is illustrated by the two graphs above. One of such factors is over exploration of a forest.
The graph shows that as consumption of lumber increases at a faster rate compared to how forest is replenished, the amount of lumber available for supply also reduces. As this goes on, biodiversity keeps declining.
In summary, we can say that:
"When forests are cut down faster than they can be replenished, biodiversity quickly decreases."
Given what we know, we can confirm that a semi-truck would have the highest gravitational attraction of the objects mentioned, while for the spaceship, its mass would <u>not change</u> during its trip.
<h3>Why would the truck have the highest gravitational attraction?</h3>
This has to do with how we calculate gravitational attraction. To summarize it greatly, this value is directly proportional to the mass of the object in question. The <u>more </u><u>massive </u>the object, the <u>more </u><u>gravity</u> it will produce. Therefore, since the semi-truck is the largest, it will have the greatest gravitational attraction.
<h3>Why does only the mass of the spaceship remain constant?</h3>
This has to do with the relationship between each value and the situation described. The acceleration and velocity will change as the ship loses fuel and is affected by the gravity of the earth and moon. The weight of the ship is also affected by gravity, whilst the mass is a physical property that <u>does not depend </u>on any of these and therefore <u>does not change</u>.
Therefore, we can confirm that a semi-truck would have the highest gravitational attraction of the objects mentioned, while for the spaceship, its mass would not change during its trip.

Air, water, and other organisms as a form of symbiotic relationships
Answer:
The best answer to your question would be as follows: The most likely result will be 1. That the rabbits from 1955 injected with the 1955 virus will have a lower survival rate than those same rabbits injected with the 1980 virus; and 2. that the rabbits from 1955 injected with the 1980 virus will have a lower rate than rabbits from 1980 injected with the 1980 virus.
Explanation:
The explanation as to why comes from the knowledge of evolution and especially with knowing that the Myxoma virus in European rabbits is the perfect example of virus-host co-evolution. Although according to the research published on this matter in 1998, Myxoma was not lethal to its natural rabbit hosts, it became so for the European groups that were in Australia. In the case of this hypothetical situation, evolution, and immune preparation to respond to a virus, to keep it in check, and for it not to be lethal is the key. In the 1955 rabbits, the exposure was just recent, therefore they had not had the time to develop defensive mechanisms, and much less evolutionary responses that would prevent the virus from being lethal. And in the second case, the virus from 1980 will have evolved much more than the 1955 rabbits to which it was injected, and therefore, again, a lethal situation will ensue.
