Q6.2. There are many diseases that do not infect a person more than once, such as chicken pox
and measles. What is responsible for this lifetime immunity?

The innate immune response, because barriers to entering the body improve with age.

The innate immune response, because adults have more white blood cells than children.

The acquired immune response, because antibodies are developed from previous infections.

The acquired immune response, because it responds rapidly to broad classes of pathogens.

Answers

The responsible for this lifetime immunity is the acquired immune response because antibodies are developed from previous infections. The generation of antibodies is a response to these infections.

The acquired immune system eliminates pathogenic organisms and any toxic molecules they produce.

The acquired immune system has two mechanisms of action: humoral immunity and cellular immunity.

Humoral immunity, also known as antibody-mediated immunity, involves the activation of specific blood cells (B cells) and subsequent secretion of antibodies when in contact with a pathogen.

Thus, the acquired immune system develops specific antibodies as a response to infections (e.g., chickenpox and measles).

Stem cells are used to treat some human diseases.
Stem cells can be collected from early embryos. These stem cells have not begun to
differentiate, so they could be used to produce any kind of cell, tissue or organ. The
use of embryonic stem cells to treat human diseases is new and for some diseases,
trials on patients are happening now.
Stem cells can also be collected from adult bone marrow. The operation is simple
but may be painful. Stem cells in bone marrow mainly differentiate to form blood
cells. These stem cells have been used successfully for many years to treat some
kinds of blood disease. Recently there have been trials of other types of stem cell
from bone marrow. These stem cells are used to treat diseases such as heart
disease
Evaluate the use of stem cells from embryos or from adult bone marrow for treating
human diseases
You should give a conclusion to your evaluation.

Answer:

The respiratory system works directly with the circulatory system to provide oxygen to the body. The primary function of the respiratory system is to deliver oxygen to the cells of the body's tissues and remove carbon dioxide, a cell waste product.Respiratory systems work together to circulate blood and oxygen throughout the body.The respiratory system subdivides into a conducting portion and a respiratory portion. The majority of the respiratory tree, from the nasal cavity to the bronchi, is lined by pseudostratified columnar ciliated epithelium. The bronchioles are lined by simple columnar to the cuboidal epithelium, and the alveoli possess a lining of thin squamous epithelium that allows for gas exchange.The conducting piece of the respiratory system consists of the nasal cavity, trachea, bronchi, and bronchioles. The luminal surfaces of this entire portion have a lining of ciliated pseudostratified columnar epithelium and contain goblet cells. Their role is to secrete mucus that serves as the first line of defense against incoming environmental pathogens. Cilia move the mucus-bound particulate up and away for expulsion from the body. The various types and abundance of cells are dependent on which region of the airway they are.

Enzyme activity generally increases as temperature increases within an enzyme’s optimal range because an increase in temperature causes an increase in molecular motion. This increase in molecular motion results in the enzyme and its substrate coming into contact with each other more often. At too high a temperature, however, the enzyme will become denatured and no longer be able to function. As the video describes, that is what happens when someone has a high fever.

What do you think happens to enzyme activity as temperature decreases outside an enzyme’s optimal range? Explain your answer in terms of molecular motion.

Answers

This most reliable temperature is commonly around human frame temperature (37.5 °C) for the enzymes in human cells. Above this temperature, the enzyme shape begins to interrupt down denature given that at better temperatures intra- and intermolecular bonds are broken because of the enzyme molecules' advantage of even greater kinetic electricity.

Each enzyme has a temperature variety in which a maximal charge of response is accomplished. This maximum is referred to as the temperature most desirable of the enzyme. The most excellent temperature for maximum enzymes is set at ninety-eight. 6 tiers Fahrenheit (37 ranges Celsius). There also are enzymes that work nicely at decreased and better temperatures.

Most activity is accomplished on the enzyme's ultimate temperature. The lively website online of the enzyme modifications shape as the temperature rises above the surest temperature, resulting in a decline in interest. Above and under the highest quality temperature, activity decreases.

Most enzyme functions are done at 37∘C in humans due to the fact the enzymes are capable of holding their structure at that temperature, allowing it to break down complex molecules efficiently.
