The Roberts family have had a large family garden for several years. Every autumn, after the first frost, they pull up the dead plants
and cover the garden rows with black plastic. When it is spring and planting time, they plant seeds though holes they have poked in
the plastic. Why do the Roberts use the plastic covering?
A)
The black plastic keeps the weeds from growing in the bare soil.
B)
The black plastic keeps the soil warm so the seeds will grow in the spring,
The black plastic helps the organisms that live in the soil survive the
winter
D)
The garden space will be covered with grass and animals will graze in the
area.

Answers

Answer:

ANSWER IS A

Explanation:

A black plastic mulch conserves soil moisture by preventing it from evaporating. Only the exposed soil in the holes where the vegetable plants are growing lose water to evaporation. This means that more moisture is available in the surrounding soil for plant roots, and you spend less time on watering the growing crops.

Explain why the Roberts family uses plastic covering.

Autumn is the season when trees lose their leaves. That is the reason Roberts family pull up the dead plants and cover the garden rows with black plastic.

Spring is the season of planting. It is a season when plants spring from the ground and trees come into blossom, following winter and preceding summer.

The plastic covering prevents weeds from growing on the bare soil.

Weeds are unwanted plants grown at a place at a period of time. Any plants that grows where it is not wanted is weed.

Therefore,

The reason why the Roberts family uses plastic covering is because "The black plastic keeps the weeds from growing in the bare soil".

evolution of octopus

Answers

Just when we thought octopuses couldn't be any weirder, it turns out that they and their cephalopod brethren evolve differently from nearly every other organism on the planet. ... When an organism changes in some fundamental way, it typically starts with a genetic mutation - a change to the DNA.

Octopuses are known to be highly intelligent for invertebrates and display an ability to solve complex problems. Until now the origins of cephalopods, which evolved from ancient marine molluscs with shells, have been shrouded in mystery.
