The Plasma membrane maintains the homeostasis throughout a cell because it filters what substances go in and out of the cell. If there is too much of a substance in a cell the plasma membrane quickly disposes it and when there is not enough of a substance in a cell the plasma membrane lets the substance in.

or this

A major role of the plasma membrane is transporting substances into and out of the cell. The plasma membrane is selectively permeable, allowing only certain substances to pass through. ... Cell transport helps cells maintain homeostasis by keeping conditions within normal ranges inside all of an organism's cells.

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.

Answer:

(A) RNA like DNA is a carrier of genetic information and contains the nitrogen bases adenine, guanine and cytosine.

Explanation:

RNA is a single stranded molecule which is replicating molecule that plays its role evolution of different stages. DNA is double stranded molecule that is stable under alkaline conditions and perform various functions in different body parts. RNA provides template on which DNA nucleotides assemble.

RNA can be observed to self-replicate without the assistance of proteins, while DNA always requires protein-based enzymes to replicate.

(B) is the best alternate hypothesis

RNA is a nucleic acid that has a single-stranded structure. RNA is also a genetic material. It helps in coding, decoding, and gene expression.

Thus, the hypothesis (B) RNA can be observed to self-replicate without the assistance of proteins, while DNA always requires protein-based enzymes to replicate is the correct option.

Answer:

mitochondria

Aerobic respiration is characteristic of eukaryotic cells when they have sufficient oxygen and most of it takes place in the mitochondria.

Explanation:

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.

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.

Answer:

The correct answer is - option C. A gene mutation interferes with cell cycle control mechanisms, resulting in uncontrolled cell proliferation.

Explanation:

Genetic mutations resulting in the change or absence of any regulatory proteins that used during checkpoints can result in the mechanism of turning on or turning off the cell cycle or allow a cell to move further for the division. Due to this change, the checkpoints are not able to prevent it from division.

Uncontrolled multiplication or proliferation of the cell, resulting in tumor development or cancer.

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

Click to play an animation of blood flow through 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.

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.
