Answer:
Explanation:
Environmental changes occurs from time to time, we have the short term changes that do not last for a very long time and the long term changes that last for a while. Accumulate of short term changes can extend to long term as some of the long term effects are as a results of short term changes in the environment.
Short term environment changes can be favourable to some organism and adversely affect others. Raining season causes increase in growth and development of most plant species but a long period of drought and dryness makes its hard for some plant to strive while some plants can strive well in long period of drought. This makes the two changes different, the both have individual effects on plants response.
Answer:
physical process of atoms or molecules moving apart within a gas or liquid.
Explanation:
The right answer is True.
At the global level, climate change will contribute to the disruption of the Earth's natural ecosystems, which could lead to the extinction of wild animal species and plants. It is mainly the impact of climate change on habitat and ecosystems that will dictate the impacts on biodiversity (by expanding them or the opposite).
Climate change will profoundly affect agricultural and forestry production. The effects in terms of production potential will be very variable depending on the regions and plant cover. They can result in an overall tendency for moderate stimulation in temperate climates and for limited warming at 2 ° -3 ° C.
Answer:
11) A. The optimum pH of an enzyme is 6.6
12) C. A control group
The main difference between a plant cell and the animal cell is the presence of cell wall.
In the plant cell, the cell wall is present, but in the animal cell, the cell wall is absent.
Hence, in the onion cells, the cell wall around the cell would be clearly visible, whereas in the case of cheek cell, the cell would only be lined by a cell membrane, a cell wall would not be present.
Further, the plant cell would have the chloroplast, as they perform photosynthesis, but the animal cell would not have chloroplast. Unlike animal cell, the central vacuole in the plant cell is bigger and clearly visible.
