What are the reactants and the products in this equation?<br><br> 2H2 + O2 → 2H2O
Hitman42 [59]

Answer:

Reactants: hydrogen and oxygen

Products: water

Explanation:

The reactants are what goes into a reaction, i.e. what is reacting. The products are what is formed. The reactants are usually shown on the left, and the products are usually shown on the right.

We can see in this equation that hydrogen (2H2) is reacting with oxygen (O2) to form water (2H2O). Therefore the reactants are hydrogen and oxygen, and the product is water.

marysya [2.9K]

Answer:

Option C,  traits can be dominant or recessive, and the recessive traits were obscured by the dominant ones in the F1.

Explanation:

Complete question-

Mendel accounted for the observation that traits which had disappeared in the F1 generation reappeared in the F2 generation by proposing that

Select one:

a. new mutations were frequently generated in the F2 progeny, "reinventing" traits that had been lost in the F1.

b. the mechanism controlling the appearance of traits was different between the F1 and the F2 plants.

c. traits can be dominant or recessive, and the recessive traits were obscured by the dominant ones in the F1.

d. the traits were lost in the F1 due to dominance of the parental traits.

e. members of the F1 generation had only one allele for each trait, but members of the F2 had two alleles for each trait.

Solution -

In the Mendel’s experiment, some traits which were absent in the F1 generation appeared in the second generation cross. By this he concluded, that the traits exressed in the F1 generation were dominant and hence they capped the expression of traits associated witl recessive allele. He classified the traits in F2 generation as recessive, because these traits can occur only when they are in pair i.e they form individuals with homozygous recessive genotype.  

For instance – If “R” is allele for dominant red color trait and “r” is the allele for recessive white color trait, then the cross between true breeding red flowers and white flowers will produce following offspring  

RR * rr

Rr, Rr, Rr, Rr

Thus, in F1 generation all the offspring are heterozygous red

F2 generation-  

Rr * Rr

RR, Rr, Rr, rr

The recessive trait of white colored flower reappears in second generation.

Hence, option C is correct

A student left a piece of meat uncovered on a kitchen counter overnight. In the morning, he saw that little organisms were crawl
Zigmanuir [339]
What this student thought was happening is called spontaneous generation. Spontaneous generation is a body of thought on the ordinary formation of living organisms without descent from similar organisms

HOWEVER, the student was wrong because it is impossible for organisms to be spawned out of nothing. The organisms appeared due to bacteria on the meat and in the air.
