If the birth rate in a population is 40, and the death rate in that population is 15, then the population will be experiencing growth. The growth will be 25 on every 1,000 people. If this trend continues for longer period, then the population will start to become younger and younger, making the basis of the population pyramid wider, while the top part of it smaller and smaller. This demographic situation in modern times seems to be present only in the less developed countries, with the majority of the transitioning countries having much decreased population growth, and the more developed countries having more deaths than births, thus being aging populations.
The human gene for insulin production is identified and removed using enzymes called restriction enzymes. The same restriction enzymes are used to cut open a plasmid (a small, circular section of DNA).
A. Kingdom fungi because fungi are in that kingdom and they decompose organisms
I am going to assume you meant the "first trophic level" of the ecosystem. The first tropic level of an ecosystem is made up of producers, so the answer is C, Acorns.
<span>The grasslands typically lie in the middle of large lanmasses, or the interior of continents, where rivers are most likely to flow far away from seawater sources. Here the ever
present value of water can be seen, as it supplies the source of life to all the plants and animals in the ecosystem in a lush and relatively cushy environment when compared to
the biomes like the desert or savannah.</span>
