90 mammal species become extinct in the period 1901-2000 than became extinct in the period 1801-1900.

Extinction is a situation in which something no longer exists. Their can be many reasons associated like species have been hunted to the point of extinction, scarcity of food or natural disasters.

Their are two main types of extinction firstly Mass extinction that has occurred only five times in history. The other is Background extinctions which occurs over longer period of time and are considered important in natural extinction rate.

A given mass of oxygen at room temperature occupies a volume of 500. 0 ml at 1. 50 atm pressure. what pressure must be applied t
andreev551 [17]

5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.

<h3>Given</h3>

Mass of oxygen at room temperature =500.0 ml

Volume of pressure = 50 atm pressure.

The gas to a volume = 150.0 ml

<h3>Explanation</h3>

The volume decreases by the factor = 500.0 mL / 150.0 mL

                                                             = 10 / 3

The pressure of the gas increased by a factor of 10/3 , which would make its final value equal to

P_{final} = \frac{10}{3} * 1.50 atm

          = 5.00 atm

So, 5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.

I’m having trouble understanding this can someone plz explain?
Leni [432]

Answer:

look at the pictures

Explanation:

1. If we cross the parental generation which is RR x rr, the probability of the F1 generation to get  rough coat is 100% and they will be a carrier of the recessive trait smooth coat.

Since the phenotypic ratio is 100% heterozygous Rr, in crossing the F1 to get the F2, we will use the genotype Rr. To get the F2, use the cross  Rr x Rr.

The phenotypic ration for F2 is 3:1. There is 75% to get rough coat and 25% smooth. The answer is based on the result on the Punnett square. On the other hand, the genotypic ratio is 1:2:1. There is 25% probability to get RR genotype, 50% Rr, and 25% rr.

2. Since the two parental mice got 6 albino offspring and 5 brown mice offspring, it is approximately 50%. it takes a parental mice who is Brown that is carrying an albino trait crossed with an albino to get offspring with almost the same number. Therefore, the genotype of the brown mice is Aa.
