Acid rain contains chemicals that can break rocks. Which describes this interaction?
A) hydrosphere and geosphere
B) geosphere and biosphere
C) biosphere and atmosphere
D) atmosphere and hydrosphere
E) hydrosphere and biosphere
The correct answer is A) Hydrosphere and geosphere
Explanation:
Planet Earth comprises different systems or spheres. Moreover, these systems often overlap or interact. This occurs in the case of acid rain that breaks rocks. Acid rain as well as other forms of water such as snow, hail, liquid water in rivers, etc. belongs to the hydrosphere, which includes all water (H2O) on Earth. On the other hand, the rocks belong to the geosphere, which comprises all the surface and materials in it such as rocks or minerals. This implies in this context the rocks from the geosphere interact with the rain of the hydrosphere.

What substance can move across a barrier by osmosis? Give the name
Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
To tell the name of substance that can move across a barrier by osmosis. water can move across barrier during osmosis.
What is osmosis?Osmosis is a special case of diffusion that involves the passive movement of water molecules across a semi-permeable membrane.
What kind of a process is it?It is a passive process.
What drives it?The internal energy of solvent molecules drives it.
What can move across by osmosis?Water molecules move by osmosis.
What other molecules can move passively?Other molecules move by the process of simple diffusion.
Gases like O₂ and CO₂; hydrophobic molecules like benzene; small polar uncharged molecules like H2O and ethanol.

When Barium chloride is formed, what questions will the student need to know prior to making the formula?
O A. What group or family does barium belong to?
O B. What is the state of matter of each element that comprises the final formula?
Exhibits
OC. What are the numbers of valence electrons for each atom?
O D. Are barium and chlorine elements?
Answer: What are the numbers of valence electrons for each atom?
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
The cations and anions combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral ionic compound.
The oxidation states are known by their ability to gain or lose electrons which is decided by the number of valence electrons.

2. Many people believe that
a mutation will always result
in the formation of a deadly
tumor, or the development
of a major body defect.
Explain why this is incorrect.
Answer:
A mutation is simply an error in the copying of DNA it generally does not have major effects. Mutations are changes in the DNA sequence.
Tumors form by an uncontrolled error in a stage of mitosis that continue to generate cells that aren't correct and eventually lead to tumors.
Explanation:
This is incorrect because not all mutations results in tumor or
development of a major body defect.
What is Mutation?Mutation refers to the changes or alterations which occur in the
nucleotide sequence of a DNA.
AA major body defect only occurs if the change in DNA affects a particular
structure or function of the part involved. Tumor on the other hand is
formed when uncontrolled errors in mitosis during growth and
replacement of tissues.

Which of the following statements correctly describes the difference between the semiconservative model of DNA replication and the conservative model of DNA replication?
A.The semiconservative model states both strands of DNA remain together after replication and the conservative model states both strands separate.
B. The semiconservative model states single-stranded DNA strands are used as a template strand to create newly synthesized DNA strands and the conservative model states only one side is used as a template.
C.The semiconservative model states the DNA strands are randomly paired with a newly synthesized DNA strand and the conservative model states only new strands are paired.
D.The semiconservative model states the two original DNA strands separate and are used as template strands to create newly synthesized DNA strands and the conservative model states the two original strands remain together.
Answer: B.
Explanation: As the DNA double helix is unwound by helicase, replication occurs separately on each template strand in antiparallel directions. This process is known as semi-conservative replication because two copies of the original DNA molecule are produced. Each copy contains one original strand and one newly-synthesized strand.
The statement that correctly describes the difference between the semi-conservative model of DNA replication and the conservative model of DNA replication is as follows:
The semi-conservative model states single-stranded DNA strands are used as template strands to create newly synthesized DNA strands and the conservative model states only one side is used as a template.Thus, the correct option is B.
What is DNA replication?DNA replication may be defined as a type of biological process that deals with the synthesis of two identical replicas of DNA from one original DNA molecule during cell division.
The semi-conservative model of DNA was proposed by Watson and Crick. This model implies that each double helix of DNA is composed of one new and one old strand.
In semi-conservative replication, the parental double helix is half conserved and each parental single strand remains intact. While in the conservative model of DNA replication, the entire original form of the DNA double helix function as a template and synthesize a new double helix.
Therefore, the correct option for this question is B.
