Ploughing and turning over the soil aerates the soil so the roots of plants are able to thrive well. Ploughing the roots of leguminous plants back to the soil returns nutritents and organic matter to the soil organically rather than using synthetic fertilisers which are potentially hazardous to the environment.

In addition, the papillary layer contains phagocytes, defensive cells that help fight bacteria or other infections that have breached the skin. This layer also contains lymphatic capillaries, nerve fibers, and touch receptors called the Meissner corpuscles.
Answer:
In some mice, fur color is inherited through incomplete dominance. The colors that are possible are black fur, white fur and grey fur. Grey is the trait that is inherited through incomplete dominance. Scenario: a grey fur male mouse and a grey fur female mouse have 8 babies. The offspring that result are: 2 black fur, 5 grey fur and 1 white fur. But this is not what is statistically expected from that cross. Explain why this is still a probable outcome. This is as a result of mutation
Explanation:
Mutation is the sudden change of a gene, from the above explanation mating of an incomplete grey fur dominance with an incomplete grey fur dominance should not have had offspring with 2 black fur, 5 grey fur and white fur. Normal mating should have produced also an incomplete grey fur dominant offspring
Answer:
a.Brain
Explanation:
Hypothalamus: The hypothalamus is in the lower central part of the brain. It links the endocrine system and nervous system. Nerve cells in the hypothalamus make chemicals that control the release of hormones secreted from the pituitary gland.
