How earthworm help fill to the soil. Explain at least 4 facts

1 answer:

6 0

Earthworms are segmented, tube-shaped worms belonging to phylum Annelida. These are habituating on healthy soils digesting live or dead organic matter. The following are benefits of an earthworm to a soil:

*Earthworms create water way systems, that is, water can seep quickly into the soil, by digging burrows vertically.

*Earthworms forms lasting burrows or mingling the soil with organic matter to make the soil more porous, thus, more oxygen to help the plants’ roots.

*Earthworms reduce the firmness of the soil and improve the cultivation of land.

*Earthworms consume organic matter as well as mix it with the soil. <span> </span>

Answer: B. If the market demand curve becomes more elastic, the firm's demand curve will become more elastic

Explanation:

Monopoly is a market structure whereby there is just one single supplier for a particular good or service. The monopolist controls the price.

We should note that the monopolist enjoys market power due to theofact that its product has an inelastic demand that is, a price change will have a minimal impact on the demand.

But the monopoly power will reduce in a case whereby the market demand curve becomes more elastic, then the firm's demand curve will become more elastic as well.

Twin studies most clearly indicate that ________ exert(s) a strong influence on the development of our unique personality traits

nexus9112 [7]

The answer is Fraternal twins. This twins usually don't look like exactly the same because they don't share the same genetic material, they can't be distinguished as twins. This type of twins grow and born together in the womb from a unique fertilized egg.

Karl von baer also lent proof toa theory of evolution. what did he do

zmey [24]

Answer: Karl Von Baer was an Estonian biologist and generalized the observations around embryology into laws bearing its name.

His laws indicate that the earlier we are in the embryonic phase, the closer the classes of distant organisms look to each other. As embryos develop, they diverge further from embryos of other species.

The von Baer sequence poses more problems for evolutionary mythology since natural selection cannot explain the pattern of embryonic development. Natural selection does not want to know if a trait is widespread or specific. It does not see attributes so it cannot sort them according to a special sequence.

What is the kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s? (Formula: KE =mv2)

jekas [21]

<h3><u>Given</u><u>:</u><u>-</u></h3>

Mass,m = 0.5 kg

Velocity,v = 10 m/s

Find the kinetic energy of a ball.

<h3><u>Formula</u><u> </u><u>used:-</u><u> </u></h3>

Kinetic energy = 1/2 × m × v²

<h3><u>Solution:-</u><u> </u></h3>

We know that,

Kinetic energy = 1/2 × m × v²

★ Substituting the values in the above formula,we get:

Kinetic energy = 1/2 × 0.5 × 10²

Kinetic energy = 1/2 × 5/10 × 100

kinetic energy = 5/10 × 50

Kinetic energy = 5 × 5

Kinetic energy = 25 Joules
