Answer:

True

Explanation:

In a natural selection, the frequency of an allele not necessarily increases always. The frequency of an allele decreases sometimes in natural selection. There are different modes of natural selection –  

a) Mutation – When a new allele is created

b) Random mating

c) Random fertilization  

d) Recombination  

A common example of natural selection in which the genetic variation decreases is known as founder effect in which the population starts ascending from a small population.

A drought killed all the plants in an agricultural farmland. Gradually, due to wind and some birds from nearby areas, new plants
OverLord2011 [107]

Use process of elimination. From what you gave me to read, you can cross off competition. A drought killed the plants and not competition to live. Go down the list of words and look up the definition. Look at nudation and ecesis later because they are different words that may or may not be challenging to understand. You know what reaction and migration is without looking it up. Once you cross off all words answers that don't match up, ask yourself, which remaining answer goes? Nudation is basically new plants that have successfully started growing after a huge environmental change. Ecesis is sort of similar however, the establishment in a new habitat or environment is not from a big change. Therefore, nudation is the correct answer.

What will be the theoretcal yield of tungsten(s) ,W, if 45.0 g of WO3 combines as completely as possible with 1.50 g of H2? WO3(
7nadin3 [17]

Answer:

Theoretical yield of tungsten produced = 35.6836915592  ≈ 35. 68 g

Explanation:

The chemical equation can be expressed as follows;

WO3 (s) + 3H2(g) → W(s) + 3 H20(g)

Note that the equation is already balanced.

Molecular Mass of WO3= 183.84 + 15.999 × 3 = 183.84 + 47.997  = 231.837 g

From the equation 1 mole of WO3 reacts with 3 mole of hydrogen molecule.

Molecular mass of tungsten(W) = 183.84 g

1 mole of tungsten was produced from the chemical equation.

WO3 (s) + 3H2(g) → W(s) + 3 H20(g)

From the equation,

231. 837 g of WO3 produces 183.84 g of tungsten

45.0 g of WO3 will produce ?

grams of tungsten produced = 183.84 × 45 /231.837

grams of tungsten produced = 8272.8 /231.837

Theoretical yield of tungsten produced = 35.6836915592  ≈ 35. 68 g

Energy is decreasing by 500 because some of it is turned into heat energy.

Explanation:

when an animal/creature consumes another living thing and or something that has energy it is decrease to a certain amount because some of the energy that the original animal/creature had is turned into heat energy because they use some of the energy for themselves to survive and live.

For example:

A flower is a producer because it produces energy and gets it gets eaten by a deer and some energy gets changed to heat and the other is consumed by the consumer (the deer) and so on.
