<span>Biotechnology is a set of techniques by which human beings modify living things or use them as tools. In its modern form, biotechnology uses the techniques of molecular biology to understand and manipulate the basic building blocks of living things. The earliest biotechnology, however, was the selective breeding of plants and animals to improve their food value. This was followed in time by the use of yeast to make bread, wine, and beer. These early forms of biotechnology began about ten thousand years ago and lie at the basis of human cultural evolution from small bands of hunter-gatherers to large, settled communities, cities, and nations, giving rise, in turn, to writing and other technologies. It is doubtful that, at the outset, the first biotechnological understood the effects of their actions, and so the reason for their persistence in pursuing, for example, selective breeding over the hundreds of generations necessary to show much advantage in food value, remains something of a mystery.</span>
An increase in biodiversity can either cause over-population of several different species or an increase in competition factor(s). Those are the most common results.
Answer:
The cells on the shaded side of the plant will shrink, causing the opposite side of the plant to grow toward the window.
Explanation:
The cells on the shaded side of the plant will shrink, causing the opposite side of the plant to grow toward the window.
Hydrogen ions are released in the cells on the shaded side of the stem. As a result, the pH of the cells decreases that in turn activates expansins (an enzyme). This enzyme causes the opposite side of the plant to grow toward the window.
It is known as facilitated transportation .
Luteinising hormone stimulates the corpus luteum to produce progesterone, which is required to support the early stages of pregnancy, if fertilisation occurs.
