I think 1 and 2 are natural numbers less than 3
Recombinant DNA techniques, for example, increase milk productions in cows. Another example would be, transgenic salmon grow faster than wild salmon.
Answer: D. at most 10
Explanation:
Using the energy pyramid, the ratio of grassland to primary consumer to secondary consumer is: 100:10:1 respectively.
Thus if the grassland supports 100 cattle (primary consumer), the numbers of humans (secondary consumer) the cattle can feed will be;
100/10 = 10.
Generally, the sun observes a solar cycle of eleven years. In this cycle, there are fluctuations in the activity, such as the ejected levels of solar radiation, and in the appearance of the sun, such as changes in the amount and size of sun spots, solar flares and other phenomena that occur on the sun's surface.
These changes also affect phenomena on earth, especially the auroras.
