Answer:
If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell's volume will remain stable. If the solute concentration outside the cell is the same as inside the cell, and the solutes cannot cross the membrane, then that solution is isotonic to the cell.

What does gyrase do during DNA replication?
Explanation:
DNA gyrase is an VERY important bacterial enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA. Gyrase categorized to a class of enzymes known as topoisomerases that are involved in the control of topological transitions of DNA. The mechanism by which gyrase is able to influence the topological state of DNA molecules is of inherent interest from an enzymological standpoint. Much attention has been focused on DNA gyrase as the intracellular target of a number of antibacterial agents as a paradigm for other DNA topoisomerases. Current knowledge concerning DNA gyrase by addressing a wide range of aspects of the study of this enzyme. I hope this makes sense to you!
A student attaches a rope to the handle of a chest loaded with a few books, while the other end of the rope is tied to a spring scale. The student pulls the scale with just enough force to set the chest in motion and records the force applied on the spring scale. The student repeats the experiment with more books in the chest and records the data in a table.
What can be concluded from the data?
As the mass of the chest increases, less force is required to pull it.
As the mass of the chest increases, less force is required to pull it.
As the mass of the chest increases, more force is required to pull it.
As the mass of the chest increases, more force is required to pull it.
The amount of frictional force increases as the mass of the chest decreases.
The amount of frictional force increases as the mass of the chest decreases.
The amount of frictional force decreases as the mass of the chest increases.
The amount of frictional force decreases as the mass of the chest increases.
Answer:
As the mass of the chest increases, more force is required to pull it.
Explanation:
Mass is a measure of the inertia of a body. Inertia means reluctance towards motion. A heavier object has a greater degree of inertia than a lighter object.
Hence, the student will notice that more force is required to move a heavier chest of books than a lighter one.
Therefore, as the mass of the chest increases, more force is required to pull it.

In sexual reproduction, how many genes does an offspring receive for each trait?
Answer:
__________
Explanation:
In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent.
Answer:
Each parents gives of half of the genes acquired by the offspring. 46 chromosomes or 23 pairs.
Explanation:
". Each gamete contains half the number of chromosomes, or genetic material, of the organism. So, each sperm contains 50% of the father's genes and each egg contains 50% of the mother's genes. This makes gametes different from other cells in the body. A basic human body cell contains 46 chromosomes, but the egg and sperm only contain half that number, or 23 chromosomes. Why? Well, when an egg and a sperm come together, which is a process called fertilization, they contribute 23 chromosomes each. Add 23 and 23 together, and you get one happy 46-chromosome-containing fertilized egg that can now develop into a new human.
Meiosis
Gametes are produced by a type of cell division known as meiosis. It's meiosis that reduces the number of chromosomes in the cell down to 23. It's also meiosis that makes gametes genetically different from one another. After the cell division takes place, each sperm and each egg has its own unique genetic makeup. In other words, meiosis can be thanked for giving Junior his cute mismatched ears. "
Mendel crossed wrinkle-seeded (rr) plants with pure round-seeded plants (RR). What percentage of the resulting generation had wrinkled seeds?
Mendel crossed wrinkle-seeded (rr) plants with pure round-seeded plants (RR). 50% percentage of the resulting generation had wrinkled seeds.
What is Mendel's cross?Mendel first experimented with just one characteristic of a pea plant at a time. He began with flower color and cross-pollinated purple- and white-flowered parent plants. He was surprised by the results. This led to his law of segregation.
A dihybrid cross is a breeding experiment between two organisms which are identical hybrids for two traits. In other words, a dihybrid cross is a cross between two organisms, with both being heterozygous for two different traits.
For monohybrid cross, Mendel began with a pair of pea plants with two contrasting traits i.e., one tall and another dwarf. The cross-pollination of tall and dwarf plants resulted in tall plants. All the hybrid plants were tall.

HOW DOES THE MEIOSIS PROCESS WORK ?
What is different between meiosis and mitosis?
Whats the different between haploid and diploid?
Answer:
Meiosis is broken down into several stages. Each cell in the process of meiosis involves the cell growing, dividing, splitting, and dividing again in order to produce the four cells at the end of the process. This cellular process is one of the more common processes of biology, but it is also the reason why people have some traits over others.
Explanation:
The difference between mitosis and meiosis is in the process by which each form daughter cells from a parent cell. Mitosis has one round of cellular division and genetic separation whereas meiosis has two rounds.
The key difference between haploid and diploid is that haploid is the state of having half the usual number of chromosomes while diploid is the state of having the usual number of chromosomes in the genome of a cell.

Before cells divide, they must replicate their entire genome. Explain why
replication of the genome prior to cell division is important.
Each time a cell divides into two daughter cells, its full genome is duplicated; for humans and other complex organisms, this duplication occurs in the nucleus. This minimizes the incidence of errors (mutations) that may greatly affect the resulting organism or its offspring. ...
HOPE THIS HELPED <3
Answer:
In order for all of the cells in your body to maintain a full genome, each cell must replicate its DNA before it divides so that a full genome can be allotted to each of its offspring cells. If DNA replication did not take place fully, or at all, the offspring cells would be missing some or all of the genome.

different color represents a different kind of atom.
If two atoms are touching then they are bonded
together
A. Element
B.Compound
C. Mixture of elements
D. Mixture of compounds
E. Mixture of elements and compounds
Please help me!!
Answer:
D
Explanation:
If two atoms are bonded together forming a compound.
When two elements combine together, it formed into a compound. The main difference between mixture and compound is that in compound, atoms bonded with each other chemically whereas in mixture, atoms combine together physically to each other. In compounds, atoms combine together in a fixed ratio whereas in mixture, atoms fuse together having no fixed ratio so we can conclude that compound is made up of two atoms.

The inheritance of genetic traits from parents to children follows predictable rules. Knowing that each parent contributes genes equally to each child, what determines an inherited trait such as eye color? *
A. Only the interaction between dominant genes.
B. Only the interaction between recessive genes.
C. The interaction between dominant and recessive genes.
D. The interaction between dominant and recessive genes does not determine inherited traits.
Answer:
c is right answer.
The interaction between dominant and recessive genes
Explanation:
Eye colour and blood groups are both examples of dominant/recessive gene relationships.
Eye colour
The allele for brown eyes (B) is dominant over the allele for blue eyes (b). So, if you have one allele for brown eyes and one allele for blue eyes (Bb), your eyes will be brown. (This is also the case if you have two alleles for brown eyes, BB.) However, if both alleles are for the recessive trait (in this case, blue eyes, bb) you will inherit blue eyes.
