Answer:
Global warming poses a series of challenges to agriculture, such as:
Changing rain patterns, where there are long periods of heavy rain followed by longer dry periods. That change can occur even within small regions.
The same to temperature patterns, drying up water reservoirs and actually burning up crops that, at that time, need a more humid environment.
Those changes can also trigger greater numbers of floods, droughts, and other effects on crops that livestock depend upon. That change in crops, in turn, may bring new insects that otherwise would not thrive there, decimating entire lands that were naturally protected from, those pests before.
Those are just some of the examples of climate change effects on agriculture and, therefore, to men.
True. In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection.
Answer:
Mature pollen grains contain two cells: a generative cell and a pollen tube cell. The generative cell is contained within the larger pollen tube cell. Upon germination, the tube cell forms the pollen tube through which the generative cell migrates to enter the ovary.
Explanation:
Answer:
growth, reproduction, and sensitivity
Explanation:
<em>The characteristics of living organisms displayed by the object are growth, reproduction, and sensitivity.</em>
When the organism reacted by rolling over in response to touch from the learner, it was displaying sensitivity. Sensitivity has to do with the ability of living organisms to be sensitive to things such as touches.
When the object divided, it was displaying growth and reproduction that are characteristics of living organisms. Growth can be defined in this case as an irreversible increase in the number of cells and reproduction can be defined as the production of new individuals.
By dividing into 2, the object has increased its number of cells and has also produced a new individual.
<u>Hence, the characteristics of living organisms shown by the object are growth, reproduction, and sensitivity</u>
