the smallest airway of the bronchial tree that is primarily responsible for creating bronchoconstriction. is called

Answers

Answer 1

The smallest airway of the bronchial tree primarily responsible for creating bronchoconstriction is called the bronchioles.

The bronchial tree is the branching system of airways in the respiratory system that leads to the lungs. Within the bronchial tree, the bronchioles are the smallest airways. They are responsible for delivering air to the alveoli, where gas exchange occurs.

Bronchoconstriction refers to the narrowing of the airway diameter due to the contraction of smooth muscles that surround the bronchioles. This contraction can occur in response to various stimuli, such as allergens, irritants, or inflammatory mediators. When the bronchioles constrict, the airway diameter decreases, leading to reduced airflow and increased resistance to breathing.

Bronchoconstriction plays a crucial role in regulating airflow and protecting the respiratory system. It helps control the distribution of air within the lungs and prevents the inhalation of harmful substances. However, excessive or prolonged bronchoconstriction can result in airway obstruction and difficulties in breathing, as seen in conditions like asthma and chronic obstructive pulmonary disease (COPD).

B.Convection currents in magma are a result of density differences.

C. Convection currents play a role in the movement of Earth’s inner core.

D. Convection currents in magma are caused by temperature differences.

Answers

Answer: C....Convection currents play a role in the movement of Earth’s inner core

The statement which is not correct with regard to convection currents is as follows:

Convection currents play a role in the movement of Earth’s inner core.

Thus, the correct option for this question is C.

What is Convection current?

Convection current may be defined as a procedure that significantly involves the movement of energy from one place to another. It is basically the existence of current in a fluid through convection.

The inner core of the earth has appeared as solid as compared to other parts like the crust and mantle. Most liquid particles are definitely found on the mantle of the earth's surface.

Due to the presence of excessive liquid particles and compounds, the convection current is significantly noticed there.

Apart from this, magma is also a fluid that derives current through convection. It produces in a number of ways like magma driving plate tectonics, density differences in the magma, and temperature differences.

Convection currents are basically the movement of fluid with respect to temperature or density difference within the material.

Therefore, the correct option for this question is C.

if epigenetic changes take place above the level of the genome , what would be an example of a change at the level of the genome ?

Answers

Answer:

epigenetics chamges take place.

Epigenetics is the examination of the way cells manipulate gene interest without converting the DNA series." Epi-"approach on or above in Greek, and "epigenetic" describes elements past the genetic code.

Epigenetic changes are adjustments to DNA that modify whether or not genes are grown to become on or off. These adjustments are connected to DNA and do now no longer alternate the series of DNA constructing blocks. Within the entire set of DNA in a (genome), all the adjustments that modify the interest (expression) of the genes are referred to as the epigenome.

Because epigenetic changes assist decide whether or not genes are grown to become on or off, they affect the manufacturing of proteins in cells. This law facilitates making sure that everyone produces the handiest proteins which might be essential for its function. For example, proteins that sell bone boom aren't produced in muscle cells.

What is the epigenetic pattern?

Patterns of epigenetic change range amongst individuals, in one-of-a-kind tissues inside an individual, or even in one-of-a-kind cells inside a tissue. Environmental influences, together with a person’s food plan and publicity to pollutants, can affect the epigenome. Epigenetic adjustments may be maintained from cell to as cells divide and, in a few cases.

Hence concluded that Epigenetics changes and causes cancers, by changing the genome, epigenome, or both.

Arguments for the use of stem cells in medical research are:

1. The stem cells enhance the growth and development of healthy skin tissue.

2. The cells can be used to enhance the production of collagen.

3. The study of stem cells helps in understanding the causes of disease.

Arguments against the use of stem cells in medical research are:

1. The use of stem cells for research harms human life and dignity.

2. People believe that killing blastocysts or stem cells is equal to taking a human life.

A. He should add shells that are different colors, but the same size and type, to the tank and observe which shells the hermit crabs choose.

Durning an experiment you need to keep everything the same but only change the certain things based on your theory.
Such as how the student wanted to see if the color attracted the crab. If he had changed the size and type of the shell then the crab would have chosen the bigger one as they tend to grow into larger shells.

Find 2 ways that natural gas forms. List the steps of the two carbon pathways below. Label each location with A for atmosphere, B for the biosphere, G for geosphere, or H for hydrosphere. Use P for the anthroposphere.

Answers

Answer:

Biogenic and thermogenic

Explanation:

Biogenic and thermogenic are the two ways or mechanism that is responsible for formation of natural gas. Biogenic gas is formed with the help of methanogenic organisms that is present in marshes, bogs, landfills, and shallow sediments. Thermogenic gas is formed from organic matter that is buried in the deeper earth where the temperature and pressure are very high.

The organic pathway of the carbon cycle is the pathway in which carbon moves from atmosphere, through producers, herbivores and other organisms in the ecosystems, and converted back to the atmosphere.

In geological pathway, carbon moves from the atmosphere, through the ocean to rocks and the mantle, and then back to the atmosphere.
