Question 9The process by which the positive and negative ions of a crystalline solid separate in water is called ____.

A)dissociation

B)ionization

C)saturation

D)solution

Answers

Answer 1
Answer:

Answer:

The process is A) dissociation.

Explanation:

In this process, the crystalline ions can be separated as well as split into smaller particles like radicals, ions, or atoms, generally in a reversible way.  

As an example, if an atom is dissolved in the water, a chemical bond that shares electron pairs among the atoms between a single hydrogen atom and electronegative atom is fragmented through heterolysis fission giving off a positive ion and a negative ion.
Answer 2
Answer:

A) Dissociation

Determine which strand is transcribed, indicate the polarity of the two DNA strands, and then give the sequence of bases in the resulting mRNA and its polarity.

Answers

A strand that is transcribed is called a template strand, the other one is called a coding strand. The template strand is in 3'-5' direction, and the coding strand is in 5'-3' direction. mRNA is transcribed from 3'-5' template DNA strand, so it is in 5' to 3' direction. The first codon of mRNA is called start codon and usually it is AUG.

Knowing this, we can answer the questions:

The transcribed strand must contain three nucleotide sequence complementary to AUG codon. According to the base pairing rules, it must be TAC. The strand that contains TAC, and, thus, is transcribed is
C C C T A C G C C T T T C A G G T T.
This template strand is in 3'-5' direction and the other one is 5'-3'.
mRNA transcription begins from the DNA sequence complementary to AUG codon:
DNA sequence:    3' C C C T A  C G C C T T  T C A G G T T 5'
mRNA sequence:         5'  A U G C G G A A A G U C C A A 3'
mRNA sequence is in 5'-3' direction.

Which of these processes removes carbon from the atmosphere?A) combustion
B) excretion
C) photosynthesis
D) respiration

Answers

c because plants  and trees are equal to photosynthesis and they take in carbon and lets out oxygen.

Final answer:

Photosynthesis is the process that removes carbon from the atmosphere.

Explanation:

The process that removes carbon from the atmosphere is photosynthesis. During photosynthesis, plants take in carbon dioxide from the atmosphere along with water and sunlight, and convert them into glucose and oxygen. Carbon is stored in plants' tissues and also released back into the atmosphere when plants respire or decompose.

For many women around the world, life is a seemingly unending process of childbirth, child-rearing, and hard domestic labor, while men often enjoy free time and more opportunities to socialize. What is this a result of?A) enforced gender stereotypesB) normal gender rolesC) gender stratificationD) enforced performance

Answers

The difference in the lifestyle of Men and women is a result of gender stratification. Women are more family-oriented while men are carrier-oriented. Thus, the correct option is C.

What is Gender Stratification?

Gender stratification is the inequality between the women and men regarding wealth, power, and privilege in the society. Gender is a socially structured principle and represents a hierarchical, asymmetrical, and unequal division between the men and women in society.

Because of gender stratification, women are not permitted to vote, own property, or testify in court in some societies. The gender stratification is the main reason for the different lifestyles of men and women in the society.
