Be aware of mudflows. the danger from a mudflow increases near stream channels and with prolonged heavy rains. mudflows can move

Anettt [7]

The mudflows are very dangerous and they have a great destructive power. They appear after a heavy rainfall on places that are steep. The mudflows are very fast and sudden occurrences, so usually people are caught unprepared. A mudflow is a mixture of water and lot of ground/mud, and all sorts of debris, which also contributes to it to be more dangerous.

Explain one way that HYDROGEN GAS is commercially produced

Westkost [7]

Explanation:

There are a number of ways to produce hydrogen: Natural Gas Reforming/Gasification: Synthesis gas, a mixture of hydrogen, carbon monoxide, and a small amount of carbon dioxide, is created by reacting natural gas with high-temperature steam. The carbon monoxide is reacted with water to produce additional hydrogen.

As of 2020, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming of natural gas, partial oxidation of methane, and coal gasification. Other methods of hydrogen production include biomass gasification and electrolysis of water.

In Drosophila, the genes for body coloration and eye size are on different chromosomes. Normal-colored bodies are dominant to eb

Yuri [45]

Answer:

225 flies

Explanation:

Let gene for body colour : A

Let gene for eye type : B

Parent 1 : normal body and normal eyes = AABB

Parent 2: ebony body and eyeless = aabb

F1 : AABB X aabb = AaBb ( all have normal body and normal eye )

F1 progeny is self crossed given that the two genes are on different chromosomes which means they show independent assortment:

AaBb X AaBb =

A_B_ = normal body, normal eyes = 9

aaB_ = ebony body, normal eyes = 3

A_bb = normal body, eyeless = 3

aabb = ebony body, eyeless = 1

Hence the ratio is 9 : 3 : 3 : 1

Out of the 400 flies:

(9/16) * 400 = 225 flies have normal body colour and normal eyes
