Answer:
adaptation, extinction, and the creating of new species
Explanation:
The species was a keystone species.
Keystone species are the species that ''hold the ecosystem together''.
They have an important role in the trophic networks (food chains) and often they can even afflict changes in the abiotic part of the ecosystem (change the composition of soil, purify the water, lower the effect of the wind etc)
Therefore, when a keystone species is removed it affects greatly the whole ecosystem.
If your brainstem is destroyed, the left side of your brain could not control the movements of your right hand.
Brainstem- The brainstem is the region at the base of the brain that is located between the cervical spinal cord and the deep cerebral hemispheres. It plays a crucial role in controlling some involuntary bodily functions like breathing and heartbeat.
Spinal cord- A column of nerve fibers that extends from the skull base to the middle of the back. It has three thin membrane-like layers of protecting tissue covering it. The vertebrae encircle the spinal cord and its surrounding membranes (back bones).

Answer:
a. transcription
Explanation:
<em>Sugar transport in phloem is referred to as pressure flow and it involves the movement of sugar through the phloem vascular tissue from the regions where sugar is synthesized (by photosynthesis) to other parts of the plant's body that require sugar.</em>
The parts of plants where sugar is synthesized (usually the leaf) is known as sugar source while the parts where they are transported is referred to as the source. Sources are usually areas of of high osmotic concentration and high water pressure while sinks are usually areas of low osmotic concentration and low water pressure.
<em>Hence, sugar transport in the phloem can be said to be influenced by the rate of sugar production at the source (rate of photosynthesis), turgor pressure as well as sugar concentration in sinks and sources.</em>
The only option that has no known effect on sugar transport in the phloem is transcription.
The correct option is a.
