13. The Cell Wall- provides the plant structure
Chloroplasts- preform photosynthesis
Larger Vacuole- holds excess water for the plant to use later
Answer:
They tunnel through the soil, which allows air to enter.
Explanation:
Earthworms are considered to be agriculturally friendly living organisms that hold immense importance in improving the growth and productivity of plants.
They live in the soil and feed on the debris of plants such as manure, grasses, roots and dead leaves. They extensively channel and tunnel through soils while moving that causes loosening of the soil resulting in more aeration of the soil. The more the soil aeration is, the better soil drainage is.
Studies have shown that soil containing earthworms have ten times better drainage than soils that donot have earthworms. Therefore, C is the best option.
Hope it help!
Answer:
Since the egg membrane is semi-permeable, water can move in but proteins cannot move out. If a naked egg is placed in the corn syrup the egg will shrink. This is also due to osmosis, but in the opposite direction.
Explanation:
ORF alignments above a certain threshold level with one or more genes in the database are presumed to encode a protein of similar function and such pairs are called Orthologues. They diverged by speciation.
<h3>What are orthologue genes?</h3>
Orthologue genes are genes that evolved by divergence from a common ancestor.
In general, orthologue genes have the same function in different species, but they exhibit sequence variation.
The alignment between orthologue genes exhibits sequence homo-logy in evolutionarily conserved gene regions.
