The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells
Tell me one thing you know about replication.
Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
Thats one thing ;)

Pretend you are a molecule of oxygen and you have reached the blood stream and attached to the hemoglobin on a red blood cell.
Describe as you travel through the different types of blood vessels (capillaries, arteries, and veins) as you make your journey through the different types of circulation (pulmonary/lungs, coronary/heart, and systemic/body) and reach the cells of the body.
Answer:
Blood flowing through the circulatory system transports nutrients, oxygen, and water to cells throughout the body. The journey might begin and end with the heart, but the blood vessels reach every vital spot along the way. These arteries, veins, and capillaries make for a vast network of pipes. If you were to lay out all the blood vessels of the body in a line, they would stretch for nearly 60,000 miles. That’s enough to circle the earth almost three times!
1. The Three Major Types of Blood Vessels: Arteries, Veins, and Capillaries
The different types of blood vessels and their layers
Blood vessels flow blood throughout the body. Arteries transport blood away from the heart. Veins return blood back toward the heart. Capillaries surround body cells and tissues to deliver and absorb oxygen, nutrients, and other substances. The capillaries also connect the branches of arteries and to the branches of veins. The walls of most blood vessels have three distinct layers: the tunica externa, the tunica media, and the tunica intima. These layers surround the lumen, the hollow interior through which blood flows.
2. Oxygenated Blood Flows Away from the Heart Through Arteries
The major arteries and branches of the body
The left ventricle of the heart pumps oxygenated blood into the aorta. From there, blood passes through major arteries, which branch into muscular arteries and then microscopic arterioles. The arterioles branch into the capillary networks that supply tissues with oxygen and nutrients. The walls of arteries are thicker than the walls of veins, with more smooth muscle and elastic tissue. This structure allows arteries to dilate as blood pumps through them.
3. Veins Carry Blood Back Toward the Heart
The superior and inferior vena cava
After the capillaries release oxygen and other substances from blood into body tissues, they feed the blood back toward the veins. First the blood enters microscopic vein branches called venules. The venules conduct the blood into the veins, which transport it back to the heart through the venae cavae. Vein walls are thinner and less elastic than artery walls. The pressure pushing blood through them is not as great. In fact, there are valves within the lumen of veins to prevent the backflow of blood.
4. Exchange of Gases, Nutrients, and Waste Between Blood and Tissue Occurs in the Capillaries

Capillaries are tiny vessels that branch out from arterioles to form networks around body cells. In the lungs, capillaries absorb oxygen from inhaled air into the bloodstream and release carbon dioxide for exhalation. Elsewhere in the body, oxygen and other nutrients diffuse from blood in the capillaries to the tissues they supply. The capillaries absorb carbon dioxide and other waste products from the tissues and then flow the deoxygenated blood into the veins.
5. The Constant Pumping of the Heart Maintains Blood Pressure and Supply Throughout the Body
Click to play an animation of blood pressure measurement
The blood moving through the circulatory system puts pressure on the walls of the blood vessels. Blood pressure results from the blood flow force generated by the pumping heart and the resistance of the blood vessel walls. When the heart contracts, it pumps blood out through the arteries. The blood pushes against the vessel walls and flows faster under this high pressure. When the ventricles relax, the vessel walls push back against the decreased force. Blood flow slows down under this low pressure.
Describe how radiation fog forms.
Answer:
Radiation fog forms in the evening when heat absorbed by the Earth's surface during the day is radiated into the air. As heat is transferred from the ground to the air, water droplets form. Sometimes people use the term “ground fog” to refer to radiation fog.

What type of medication have they tested using tissue grown with this
technology?
Answer:
Tissue engineering evolved from the field of biomaterials development and refers to the practice of combining scaffolds, cells, and biologically active molecules into functional tissues. The goal of tissue engineering is to assemble functional constructs that restore, maintain, or improve damaged tissues or whole organs. Artificial skin and cartilage are examples of engineered tissues that have been approved by the FDA; however, currently they have limited use in human patients.
Regenerative medicine is a broad field that includes tissue engineering but also incorporates research on self-healing – where the body uses its own systems, sometimes with help foreign biological material to recreate cells and rebuild tissues and organs. The terms “tissue engineering” and “regenerative medicine” have become largely interchangeable, as the field hopes to focus on cures instead of treatments for complex, often chronic, diseases.

What do individuals who are heterozygous for codominant traits show for a
phenotype?
Answer:
Individuals who are heterozygous for co-dominant traits show in their phenotype both traits, without mixing.
Explanation:
Codominance is a type of inheritance that does not follow the rules of Mendelian inheritance, characterized by the absence of recessive traits and two different alleles for a character that behave as dominant.
Heterozygous individuals can be observed in codominance that show two different characteristics in their phenotype, without mixing, such as cattle with spotted skin or two colored flowers.
treatment for PTSD campus be described A.multumodal multi-phasic b. atheoretical C. stress inclusion D.eclectic
Answer:
A. multimodal and multiphasic
Explanation:
Hypnosis can be defined as a mental state that is trance-like and it is typically characterized by minimal peripheral awareness, vivid fantasy, highly focused attention (concentration) and an increased level of suggestibility.
Simply stated, hypnosis is a sleep-like state and as such can be used by psychologist or therapist to reduce the sense of pain, induce relaxation, strengthen certain behaviors etc.
Hence, one of the ways in which hypnosis can be administered by psychologists or therapists is through Hypnotherapy, which typically involves the use of hypnosis in psychotherapy to treat medical conditions such as depression, eating disorders, anxiety, post-traumatic stress disorder (PTSD).
The treatment for post-traumatic stress disorder (PTSD) can be described as multimodal and multiphasic because it is characterized by series of activities and it takes place in various phases.
Which of the following statements is true?
a) only males can get an X-linked. disorder.
b) only females can get an X-linked disorder.
c) only males can get a Y-linked disorder.
Answer:
The answer is a
Explanation:
X-linked disorders result from mutated genes on the X chromosome. Males, who have only one X chromosome (i.e., they are hemizygous), will fully express an X-linked disorder. On the other hand, females, who have two X chromosomes, will be carriers of the defect in the majority of cases, and so they are usually asymptomatic.

Which of the following is false about DNA?
A. DNA is made up of units called nucleotides.
B. Any base can pair to any other base.
C. DNA contains the instructions to make proteins.
D. DNA is found in a cell's nucleus.
Answer:
b. any base pair can pair to any other base
Explanation:
Any base pair cannot pair with any other base, Adenine pairs with thymine and cytosine pairs with guanine.
• The hereditary material in humans and almost all of the living species is known as DNA or deoxyribonucleic acid.
• The majority of the DNA is present within the nucleus of the cell.
• DNA comprises the instructions to make proteins that helps to perform essential functions within the body of an organism.
• Within the DNA, information is stored in the form of a code formed of four chemical bases, that is, Adenine, guanine, cytosine, and thymine.
• The base pairs present within the DNA pairs up with each other, that is, adenine pairs with thymine only, and guanine pairs with cytosine, no other kind of pairing is found within the DNA. Each base of also attached with a molecule of phosphate and sugar.
• Together, a phosphate, base, and sugar are known as a nucleotide.
Thus, statement B is incorrect.

Which statement is true regarding the transmission of sex-linked traits in a population?
O Males cannot carry recessive alleles for sex-linked traits.
O Males cannot express dominant alleles on the X chromosome.
O Males cannot express recessive alleles on the X chromosome.
O Males cannot pass alleles for sex-linked traits to their daughters.
Answer: none of the statements are true
Explanation: Males can have a recessive copy of a X-linked gene, and can pass that on in the X containing gamete and so pass it on to daughters, but not to male offspring. Males will express whichever allele, dominant or recessive that they carry.

On your visit to New York City, you and your friend observed that the grey rats (Rattus norvegicus) in the New York subway are considerably larger than a typical West Coast rat. You decided to test whether this difference was genetic or environmental. You obtained a litter of 10 New York rat pups, and a litter of 10 California rat pups. Each of you took 5 pups from each litter and kept them in your room for 3 months, despite your roommates' protests. You fed your rats a balanced diet of dry cat food and fresh fruit and vegetables. Your friend, however, has a soft heart and gave her rats french fries, cheeseburger wraps, hot dogs, and other nostalgic New York fare. At the end of your experiment, you found that the New York and California rats that grew up in your home were exactly the same size. Your friend, however, found that her New York rats were larger than her California rats, and both were larger than your rats. So, is the difference genetic or environmental?
Explain why you concluded this.
a. Genetic
b. Environmental
c. Genotype environment interaction
d. a and b
e. b and c
f. a and c
g. a, b, and c
Answer:
d. a and b
Explanation:
The difference in the size of both rats are due to genetic and environmental because rats of both location increased in size which eats a lot of food as compared to those rats which eats balanced diet. This is due to the environment while on the the other hand, due to difference in genetics, New York rats grew larger than California rats of your friend which eats large number of food. So we can say that both genetic and environmental factors affect the rats size.
