Ublimation 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

Answers

Answer:

True

Explanation:

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.

An atom of hydrogen loses its electron. What is its charge

Answers

Answer:

When an atom of hydrogen loses its electron it becomes positively charged.

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.

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

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%
