if a parent cell has 6 chromosomes at the start of interphase, how many chromosomes will each daughter cell eventually have?

You have examined several body systems that rely and work with each other in order function properly. One very important task th

Llana [10]

The task of the respiratory system is the exchange of Oxygen and Carbon Dioxide within the body; however, the respiratory system alone has no mechanism for the transfer of oxygen from the lungs to the body for absorption and transfer of carbon dioxide from the body for expulsion. The cardiovascular system assists in this by moving oxygen-saturated blood from the lungs to different parts of the body and carbon dioxide rich blood from the body to the lungs.

What is the relationship between the transmission of light and absorption of light?

BaLLatris [955]

Answer: The relationship between absorbance and transmittance is illustrated in the following diagram: which is added below.

So, if all the light passes through a solution without any absorption, then absorbance is zero, and percent transmittance is 100%. If all the light is absorbed, then percent transmittance is zero, and absorption is infinite.

How is most DNA duplication is the body accomplished?

OverLord2011 [107]

DNA carries the information for making all of the cell's proteins. These proteins implement all of the functions of a living organism and determine the organism's characteristics. When the cell reproduces, it has to pass all of this information on to the daughter cells.Before a cell can reproduce, it must first replicate, or make a copy of, its DNA. Where DNA replication occurs depends upon whether the cells is a prokaryote or a eukaryote (see the RNA sidebar on the previous page for more about the types of cells). DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same.The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (anti-parallel) directions. The beauty of this structure is that it can unzip down the middle and each side can serve as a pattern or template for the other side (called semi-conservative replication). However, DNA does not unzip entirely. It unzips in a small area called a replication fork, which then moves down the entire length of the molecule.Let's look at the details:An enzyme called DNA gyrase makes a nick in the double helix and each side separatesAn enzyme called helicase unwinds the double-stranded DNASeveral small proteins called single strand binding proteins (SSB) temporarily bind to each side and keep them separatedAn enzyme complex called DNA polymerase "walks" down the DNA strands and adds new nucleotides to each strand. The nucleotides pair with the complementary nucleotides on the existing stand (A with T, G with C).A subunit of the DNA polymerase proofreads the new DNAAn enzyme called DNA ligase seals up the fragments into one long continuous strandThe new copies automatically wind up again

If have cardiovascular blockage what does.blood pressure do

hjlf

Heart blockage and blood pressureThe excess strain and resulting damage from high blood pressure (HBP or hypertension) causes the coronary arteries serving the heart to slowly become narrowed from a buildup of fat, cholesterol and other substances that together are called plaque. This slow process is known as atherosclerosis.
