Answer: yes, mitosis is simple cell division
Explanation: mitosis is the process by which a cell divides into two cells, each with DNA from the duplication of the two original strands (in eukaryotes, duplication of all chromosomes).
Answer:
One, two
Explanation:
When ONE parent cell divides, it divides into TWO daughter cells.
Hemophilia is a recessive sex-linked trait. A non-hemophiliac man and woman marry and
have a daughter who is a hemophiliac. The father of this child suspects infidelity and is
considering a divorce. Does he have sufficient evidence of infidelity? Explain.
The father does not have sufficient evidence of infidelity as the parent's genotype is not mentioned which could have the recessive trait of hemophilia being inherited to the daughter.
What is hemophilia?Hemophilia is a disorder which is rare which results when the blood does not clot in it's usual way as it does not have sufficient blood-clotting factors .A person suffering from hemophilia can bleed for a longer period of time resulting in blood loss.
It is almost always that hemophilia occurs genetically . Treatment of hemophilia include replacement of the specific blood clotting factor that is reduced. Symptoms of hemophilia vary from person to person depending on the level of the clotting factors.
Signs and symptoms include excessive bleeding ,large or deep bruises, pain or swelling in joints ,nosebleeds,etc.

Answer:
B. A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strand forming two separate semiconservative molecules
Explanation:
DNA Replication is an important phenomenon as far as cell division is concerned. It is the process whereby a DNA molecule doubles its content or forms two DNA molecules from one.
In the semi-conservative model of DNA replication, an enzyme called DNA helicase unwinds the double stranded DNA molecule into two single strands. The single strands are then used as template for DNA polymerase to synthesize another molecule of DNA. Hence, two separate DNA molecules comprising of one old strand and one new strand.
In your lab group, you are investigating the properties of unknown types of matter. Your teacher gives you a "detective's kit

D)
measuring the boiling point
E)
checking for reactivity with vinegar
Answer:
A: measuring the pH
E:checking for reactivity with vinegar
Explanation: I don't have one
The chemical property of the unknown substance can be measured by checking for reactivity with vinegar.
The chemical properties of a substance are those properties of a substance that we can observe by allowing the substance to be changed via a chemical reaction. In other words, chemical properties are observed by passing the substance through a chemical reaction.
Hence, the experiment that you will need to perform in order to determine the chemical properties of the unknown substance is checking for reactivity with vinegar.

Apply: Which type of moth do you think was more common before the 19th century, when most trees were light in color?
Answer:
light moths
Explanation:
yes their were most light color in most trees
Light moths was more common before the 19th century, when most trees were light in color.
What are the functions of light moths?Insects, like moths, are drawn to bright lights because they make it difficult for them to navigate. It's a common sight, particularly in the summer: The lights, like lamps, were surrounded by moths and other insects.
Most nocturnally dynamic moths are drawn to light, a peculiarity known as sure phototaxis. However, because they are phototactic, some species, like the Old Lady (Mormo maura), tend to avoid it.
No one really knows why moths are drawn to light, but there are a few theories, and they also like the smell of fermented sugar and ripe fruit, which are both food sources.

How do the hormones of the endocrine system act as a feedback mechanism for the menstrual cycle?
In positive feedback, rising levels of hormones feedback to increase hormone production. During most of the menstrual cycle, estrogen and progesterone provide negative feedback to the hypothalamus and pituitary gland. This keeps their levels more or less constant.
In negative feedback, rising levels of hormones feedback to the hypothalamus and pituitary gland to decrease the production of the hormones. In positive feedback, rising levels of hormones feedback to increase hormone production. During most of the menstrual cycle, estrogen and progesterone provide negative feedback to the hypothalamus and pituitary gland. This keeps their levels more or less constant. During days 12–14, however, estrogen provides positive feedback to the hypothalamus and pituitary gland. This causes a rapid rise in the production of estrogen by the ovaries and leads to ovulation.

3.4.3 Lab: Why are cells so small?
Answer: The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. ... That is why cells are so small.
Explanation: because they can absorb nutrients much more efficiently. Because they are smaller they can efficiently absorb enough food. ... When a cell doubles in size the volume increases much more then the surface area, which is why large cells cannot receive enough food efficiently for their volume. Cells are small because they are more efficient as smaller entities. Information within small cells is transmitted more quickly and efficiently than within larger cells. ... Thus a higher cell surface area-to-volume ratio, i.e., smaller cell size, is desired for most efficient cellular activity.
The cells are so small because their small size allows them to take in food and get rid of the waste.
The cells are the basic structural and functional unit of all organisms on earth except the Viruses. The size of the cell is so little it allows the organism to maximize the ration of surface area to volume. Smaller cells are expected to have greater ratio which promotes more molecules as well as ions to move across the plasma membrane.The small size of the cell facilitate to get the nutrients inside the cell and waste outside the cell quickly. Hence, small size of cell facilitates to get food inside and get rid of waste.Learn more about cell:

What is the importance of Mitosis in both Prokaryotic and Eukaryotic Cells
Answer:
Mitosis is the process by which the overwhelming number of cell divisions in eukaryotic organisms occur. Eukaryotes (animals, plants and fungi) typically consist of literally trillions of cells, and at any time, countless worn-out, dead or irreparably damaged body cells need to be replaces. Mitosis is the eukaryotic answer to binary fission in the single-celled prokaryotes, which is similar on the surface but simpler at the level of details.

Answer:
Mechanical waves react to different mediums in different ways. Some mechanical waves are TRANSMITTED through a medium, meaning they pass through the medium.
The way in which waves are transmitted depends upon the type of material. In SOLIDS, mechanical waves travel rapidly, because the molecules are DENSELY packed. In liquids and air, however, mechanical waves travel more SLOWLY, because the molecules are spread farther apart.
Other mechanical waves are reflected off a medium. When a mechanical wave is reflected, it BOUNCES off the medium and then travels in a DIFFERENT direction. SONAR is an application that uses sound wave reflection to determine how deep water is.
A third way mechanical waves react to a medium is ABSORPTION. When a mechanical wave is absorbed, it remains WITHIN a medium and is not transmitted to another medium.
