A Father and Mother are both carriers of the autosomal recessive condition known as albinism. They have one child, and a second child two years later. Their first child was not albino. Knowing this, you can say that the probability of the second child having albinism is Note - Albinism is the result of a lack of pigmentation in skin and other cells.​

Answers

answer: there is a 50% probability of the 2nd child having albinism.

since the mother and father are both carriers then they would both have Aa. meaning there would be a 50% chance of the child being normal (AA) and a 50% chance of the child having albinism (aa)

Both the mother and father would have Aa because they are both carriers. i.e., there would be a 50% probability that the child would be albinized (AA) and a 50% chance that the child would be normal (aa).

What is albinism?

Albinism refers to a collection of extremely uncommon genetic illnesses that are characterized by the absence of melanin at birth in either an animal or a plant.

People who have albinism either have a significantly diminished amount of melanin or none at all. Both their coloring and their eyesight may be impacted as a result of this. Albinism is characterized by extremely light or very light blonde hair, while some individuals with the condition have brown or ginger hair. The precise color is determined by the amount of melanin that is produced by the body.

A red blood cell leaving the left ventricle of the heart would take which pathway to reach the facial artery?

Answers

Answer:

Red blood cell arrives from the inferior vena cava into right atrium before it passes through the tricuspid valve into right ventricle. It then passes through the pulmonary valve into pulmonary artery before travelling through the lungs and back into the heart, this time the left atrium via the pulmonary vein.

Explanation:

hope this helps

The pathway of a red blood cell that leaves the left ventricle of the heart to reach the facial artery would be: Arch of Aorta > Brachiocephalic Trunk > Right Common Carotid Artery > Right External Carotid Artery > Right Facial Artery

The arch of the aorta can be considered as the peak of the ascending aorta.

The brachiocephalic trunk refers to the second branch to arise from the aorta.

The right common carotid artery arises as a branch of the brachiocephalic trunk of the aortic arch.

The facial artery is a branch of the external carotid artery that supplies blood to the muscles and skin of the face.

In conclusion, the pathway of a red blood cell that leaves the left ventricle of the heart to reach the facial artery would be: Arch of Aorta > Brachiocephalic Trunk > Right Common Carotid Artery > Right External Carotid Artery > Right Facial Artery.

Compare and contrast the advantages and disadvantages of wind power and geothermal power

Answers

Answer:

An Overview of Geothermal Pros and Cons:

Pros Cons

This energy source is more environmentally friendly than conventional fuel sources.  The largest single disadvantage of geothermal energy is that it is location specific.

A source of renewable energy.  Gases are released into the atmosphere during digging.

The number of exploitable geothermal resources will increase with ongoing research and development in the industry.  Geothermal energy runs the risk of triggering earthquakes.

A sustainable source of energy as its always available unlike wind and solar.  Expensive resource to tap into, with high upfront costs ranging from around $2-$7 million for a plant with a 1 megawatt capacity.

A reliable source as its easier to predict the power output from a geothermal plant with a high degree of accuracy.  Energy fluid needs to be pumped back into the underground reservoirs faster than it is depleted. Management is required to maintain sustainability.

No fuel is required.  

Increase in exploration meaning that new technologies are being created to improve the energy process.  

Pollution levels are much lower compared to fossil fuels.

It introduces the body to a virus strand(s) to initiate internal resistance, which is created after a variety of metabolical processes. The idea is that the body would develop immunity to the virus without actually "getting" the virus.

Explanation:

Answer:

When we are exposed to antigens the body sends an immune response to prevent any infection or disease. Vaccines contain the same parts of antigens that can cause diseases, though they are weakened so that they don't actually cause disease, then they trigger the immune system to produce antibodies, which then help to fight against pathogens.

In contrast, cancer cells don’t stop growing when there are enough cells present. This continued growth often results in a tumor (a cluster of cancer cells) being formed.
