Answer:

Glaciers bring quantities of minerals beneficial to plants as the water runs off melting ice.

Explanation:

Glaciers are natural reservoirs of water and minerals that may persist to dry conditions during the summer season. Ice melting provides water and minerals during the warm season, which is therefore critical for plants living in dry summer environments. Moreover, it is well-known that the 'melt-water' (i.e., water released by the melting of glacial ice) also affects downstream stream water temperatures, creating a microhabitat that may be beneficial to the life of plant species.

What was the benefit of crop rotation?

dybincka [34]

Answer:

B. Different crops could be grown on the same land.

Explanation:

Crop rotation is the process of growing different plants in the same land according to the season. Various kinds of plants require various sorts of supplements from the soil.

Changing crops on a regular basis enables the land to stay rich in nutrients, since not the majority of similar nutrients are being utilized each season. Crop rotation likewise fights against the powers of soil erosion. It also helps to improve the stability of the soil by shifting back and forth between harvests with profound roots and those with shallow roots.

____ [38]

Answer:

The % of children with webbed digits is $50$ %

Explanation:

Given -

Syndactyly or webbed digits are due to the presence of a dominant allele (S). Then the allele for normal digits would be represented by allele "s"

A normal man with normal digits and genotype "ss" marries a woman with webbed digits and has a hetrozygous genotype i.e "Ss"

If we cross Ss and ss , then the following offspring are produced -

Ss * ss

Ss, Ss, ss, ss

Out of four 2 offspring with genotype ss have normal digits and remaining two offspring with genotype "Ss" have webbed digits. Thus, the % of children with webbed digits is $50$ %
