A green pea plant (Gg) is crossed with a yellow pea plant (gg). What is the probability that the offspring will be heterozygous?
A.25%
B.50%
C.75%
D.100%
Answers
Answer:
50 percent
Explanation:
G g
g Gg gg
g Gg gg
since one of the plants are already heterozygous, only half will be heterozygous since the other plant is homzygous
There is 50% probability that the offspring will be heterozygous.
What is heterozygous?At a given gene locus, the existence of two different alleles. One normal allele and one mutant allele, or two separate mutated alleles, can make up a heterozygous genotype (compound heterozygote).
what is allele?An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome.
so, if green pea plant (Gg) is crossed with a yellow pea plant (gg), there will be 50% probability that the offspring will be heterozygous, we can find it by making punnett square so here is the solution
Hence, the correct option is B i.e. 50%

25cm3 of a 0.4M sodium hydroxide solution was diluted into 250cm3 of water. What is the molarityof the resultant solution.
Answers
Answer:
0.04 M
Explanation:
From the question given above, the following data were obtained:
Initial volume of solution (V1) = 25 cm³
Initial Molarity of solution (M1) = 0.4 M
Final volume of solution (V2) = 250 cm³
Final Molarity of solution (M2) =?
We can obtain the final Molarity of the solution by using the dilution formula as illustrated below:
M1V1 = M2V2
0.4 × 25 = M2 × 250
10 = M2 × 250
Divide both side by 250
M2 = 10/250
M2 = 0.04 M
Therefore, the resulting molarity of the diluted solution is 0.04 M

Answers
Answer:
1. 95.7 ppm
2. 6.67 ppm
Explanation:
Podemos pensar la denominación ppm como partes por millón, es un tipo de unidad que define concentración de solutos en una solución.
ppm = μg/g o si lo queremos ver en volumen, μg/mL
Quiere decir microgramos de soluto en 1 g de solución o mL de solución.
Ej 1. En primer lugar convertimos los moles de KNO₃ a gramos
0.00071 mol . 101.1 g/mol = 0.071781 g
Si pasamos los gramos a μg → 0.071781 g . 1000000 μg/ 1g = 71781 μg
Dividimos 71781 μg /750 ml = 95.7 ppm
Ej 2. Convertimos los mg a μg → 4 mg . 1000 μg/ 1 mg = 4000 μg
Ahora dividimos: 4000 μg /600 ml = 6.67 ppm

Answers
Answer: C. The university surveys 600 randomly selected students who attend the university. Correct
Explanation:
22.72 is the average atomic weight of sodium.
What are isotopes?Isotopes are different versions of a specific element.
1st isotopes of 22u = 28%
2nd isotopes of 23u = 72%
The average atomic weight of sodium be=
22 x 28 + 23 x72
=2272/100
=22.72
Hence, 22.72 is the average atomic weight of sodium.

Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage.
For those of us interested in the water cycle, sublimation is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water which bypasses the conversion to liquid stage and goes straight to the gaseous form.

Could you use filtration on a solution?
Answers
Answer:
No.
Explanation:
This is because a solution is a mixture with two substances that have already dissolved in each other and so there is no residue left. Filtration works such that part of the mixture has smaller particles that can pass through the membrane of the filter paper while the bigger particles get stuck onto the paper as residue. A solution has a uniform size particle throughout and thus filtration does not work for purifying a solution.

Hope it will help you........Final Answer: +1
Explanation/Reasoning:
Because hydrogen is an atom (not an ion), you'll write it as H (not H+). Hydrogen (H) has one proton and one electron, so if it loses its electron, it will only have one proton. Therefore, it becomes an ion of H+. This means that the charge will be +1.

Which statement is true about a reaction represented by a chemical equation that shows energy as a reactant?

A.
It absorbs energy.

B.
It releases energy.

C.
It is a replacement reaction.

D.
It is a combustion reaction.
Answers
reactants are located on the left side of the equation, meaning energy among with other reactants were needed to get the reaction going, so it absorbed energy, which is also the endothermic process. The opposite of that would be having energy on the right side with the products which means that the reaction would've released energy which is the exothermic process. Hope this helps!
