<span>A. If one essential nutrient within an ecosystem runs out, primary productivity will be limited.
A specific nutrient is need for every organism in the ecosystem. If this particular nutrient is diminished within the ecosystem then cellular processes will decreases and a great number of specie will die. </span>
I believe that plant hormonal control differs from animal hormonal control in that there are no separate hormone-producing organs in plants as there are in animals. Hormones regulate cellular processes in targeted cells locally and moved to other locations, in other function parts of the plant. Hormones also determine the formation of flowers, stems, leaves, the shedding of leaves, and the development and ripening of fruit. Plants unlike animals they lack glands that produce and secrete hormones and instead each cell is capable of producing hormones.
Answer:
Threats to the tundra biome
The oil, gas, and mining industries can disrupt fragile tundra habitats. Drilling wells can thaw permafrost, while heavy vehicles and pipeline construction can damage soil and prevent vegetation from returning. This activity also increases the risk of toxic spills.
What is the environment like in the tundra?
Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant. Tundra lands are covered with snow for much of the year, but summer brings bursts of wildflowers.

Answer:
It is important to use the regulatory sequence of a milk gene when constructing a recombinant gene used to produce a human protein secreted in milk because<em> it is capable of increasing or decreasing the expression of specific genes within an organism.</em>
Explanation:
<em>Regulatory Sequence</em> is<em> a segment of a nucleic acid molecule</em> which is capable of increasing or decreasing the expression of specific genes within an organism. Regulation of gene expression is an essential feature of all living organisms and viruses.
