Pueden una mujer y hombre (ambos normales) tener un hijo albino
Elanso [62]

Answer:

es bastante raro pero sucede que depende de los genes

ESPANOL -

El albinismo es una condición genética en la que las personas nacen sin el pigmento (color) habitual en sus cuerpos. Sus cuerpos no pueden producir una cantidad normal de melanina, el químico responsable del color de los ojos, la piel y el cabello. Entonces, la mayoría de las personas con albinismo tienen piel, cabello y ojos muy pálidos. El albinismo puede afectar a personas de todas las razas, y existen diferentes tipos de albinismo.

Algunas personas con una afección llamada albinismo oculocutáneo tienen piel y ojos extremadamente pálidos y cabello blanco. Otros con este mismo tipo de albinismo pueden tener un poco más de color en el cabello, los ojos o la piel.

Para algunas personas, el albinismo afecta solo sus ojos. Esto se conoce como albinismo ocular. Las personas con albinismo ocular generalmente tienen ojos azules. En algunos casos, el iris (la parte coloreada del ojo) tiene muy poco color, por lo que los ojos de una persona pueden verse rosados ​​o rojizos. Esto es causado por los vasos sanguíneos dentro del ojo que se muestran a través del iris. En algunas formas de albinismo ocular, la audición de los nervios auditivos puede verse afectada y la persona puede desarrollar problemas de audición o sordera con el tiempo.

Excepto por los problemas oculares, la mayoría de las personas con albinismo son tan saludables como cualquier otra persona. En casos muy raros, el albinismo de una persona es parte de otra afección que involucra otros problemas de salud además del albinismo. Las personas con este tipo de albinismo pueden tener complicaciones de salud tales como problemas de sangrado, pulmón, intestino y sistema inmunológico.

it's pretty rare but it happens it depends on the genes

ENGLISH - Albinism is a genetic condition where people are born without the usual pigment (color) in their bodies. Their bodies aren't able to make a normal amount of melanin, the chemical that is responsible for eye, skin, and hair color. So most people with albinism have very pale skin, hair, and eyes. Albinism can affect people of all races, and there are different kinds of albinism.

Some people with a condition called oculocutaneous albinism have extremely pale skin and eyes, and white hair. Others with this same type of albinism might have slightly more color in their hair, eyes, or skin.

For some people, albinism affects only their eyes. This is known as ocular albinism. People with ocular albinism usually have blue eyes. In some cases, the iris (the colored part of the eye) has very little color so a person's eyes might look pink or reddish. This is caused by the blood vessels inside the eye showing through the iris. In some forms of ocular albinism, the hearing nerves hearing may be affected and the person may develop hearing problems or deafness over time.

Except for eye problems, most people with albinism are just as healthy as anyone else. In very rare cases a person's albinism is part of another condition that involves other health problems in addition to albinism. People with these types of albinism can have such health complications as bleeding, lung, bowel, and immune system problems.

you may have read about alkaline diets that claim that you need to only eat alkaline foods in order to remain healthy according
hram777 [196]

Answer:

Mechanisms are activated where it is sought to lower the amount of free protons in the blood, that is, to reduce acidity, these mechanisms work between two large systems, the receptor system, the respiratory system and the renal system.

Explanation:

When a metabolic acidosis is entered, either by a food, or by a disease or even an intense physical activity, the lungs seek to generate hyperventilation, to increase the concentrations of oxygen in plasma and absolutely decrease the carbon dioxide concentration, thus not the blood becomes even more acidic.

On the other hand, the digestive system together with the sensory system, will warn this proprioception of the acidity of the plasma and will promote the dilution of these acids with a solvent, which is water, promoting the sensation of thirst.

Finally, the kidneys will seek to retain all the alkaline solutes to neutralize the physiological internal pH, and will release through the urine and the channels of acidic compounds, the products or acid metabolites to the external environment, that is, acid urine excretion.

Compare the normal allele for hemoglobin with the sickle cell allele. How does this difference affect the person’s red blood cel
Readme [11.4K]

Answer:

Sickle cell anemia is an inherited condition in which there aren't enough healthy red blood cells to carry oxygen through an individual's body. The red blood cells of a healthy individual are flexible and round, and they move through blood vessels with no problem, transporting oxygen successfully. However, a person with sickle cell anemia has rigid, sticky red blood shaped like sickles or crescent moons. These cells often get stuck in small blood vessels, which can slow or block blood flow and oxygen delivery to different parts of the body.

The sickle cell anemia trait is found on a recessive allele of the hemoglobin gene, while the regular red blood cell trait is found on the dominant allele. This means that a person must have two copies of the recessive allele (one from their mother and the other from their father) to be born with this condition. People who have one dominant and one recessive allele or both dominant alleles will have healthy red blood cells.
