Three RGDs are Cystic Fibrosis, Tay-Sachs Disease, and Sickle Cell Anemia

We can-in some ways-inherit these genes from our biological parents

Describe what happens to the air in the lungs when we breathe. What happens to the concentration of

Otrada [13]

When we breathe in, oxygen enters our lungs and enters small sacs in our lungs called the alveoli. In the alveoli, the oxygen diffuses INTO the bloodstream through small blood vessels, called capillaries, that surround these alveoli. The oxygen is now in our bloodstream instead of our lungs and is used in cell respiration etc.

Oppositely, carbon dioxide is diffused FROM the bloodstream TO the alveoli, also through these capillaries. The carbon dioxide is now in the lungs instead of the bloodstream and when you breathe out, the carbon dioxide is breathed out out of your lungs.

Hope this helped, even if it helped a tiny bit. :)

Genetic variation makes individuals within a species different. Fertilization results in each offspring having a copy of each ge

murzikaleks [220]

Genetics is a branch of biology concerned with the study of genes, genetic variation, and heredity in living organisms.[1][2][3]

The discoverer of genetics is Gregor Mendel, a late 19th-century scientist and Augustinian friar. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene.

Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded beyond inheritance to studying the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the context of a population. Genetics has given rise to a number of subfields, including epigenetics and population genetics. Organisms studied within the broad field span the domains of life (archaea, bacteria, and eukarya).

Genetic processes work in combination with an organism's environment and experiences to influence development and behavior, often referred to as nature versus nurture. The intracellular or extracellular environment of a cell or organism may switch gene transcription on or off. A classic example is two seeds of genetically identical corn, one placed in a temperate climate and one in an arid climate. While the average height of the two corn stalks may be genetically determined to be equal, the one in the arid climate only grows to half the height of the one in the temperate climate due to lack of water and nutrients in its environment.

Where does the sedimentary rock chalk form? from the precipitation of minerals in shallow marine environments by the lithificati

Katarina [22]

The correct answer is an accumulation of microorganisms in deep marine environments.

Chalk rock refers to a pure form of limestone produced in tropical and warm seas about 100 million years ago in the Cretaceous period. The microscopic marine algae known as coccoliths thrived in the ancient seas. Their shells were comprised of calcite. With the death of the algae, their bodies sunk to the floor of the sea and sediment of chalk got deposited.

Over many years layers of chalk sediment got deposited and resulted in compaction of loose sediment into solid chalk rock.

Deficiencies of carnitine, carnitine acyltransferases, or carnitine/acylcarnitine translocase affect the metabolism of long‑chai

vovikov84 [41]

Answer:

CPT-1 deficiency can cause:

Symptoms of low blood sugar (hypoglycemia)

Liver problems, such as an enlarged organ

Damage to the nervous system, caused by liver (liver) problems

Coma and sudden death

Heart failure

CPT-2 deficiency can affect each person differently, depending on how well the CPT-2 protein is working. Symptoms can be mild to severe. For certain periods, people with this deficiency may not have any symptoms. Very serious forms can affect newborns or babies. These are rarer.

The myopathic form of CPT2 deficiency causes milder symptoms. It does not cause heart or liver problems. People with this form generally have a normal life expectancy. Symptoms can start at any time up to age 60. They can appear if you skip meals, exercise a lot, or get sick. Symptoms may include:

Symptoms of low blood sugar (hypoglycemia)

Temporary muscle pain

Muscle damage

Muscular weakness

Dark urine

So, it can be said that the myopathic form is the least severe and is characterized by recurrent episodes of rhabdomyolysis, muscle pain and weakness triggered by prolonged physical exercise, fasting, viral illness or extreme temperatures. The severe infantile form is characterized by severe intolerance to fasting, leading to metabolic disorders such as hypoketotic hypoglycemia and hepatic encephalopathy. The neonatal lethal form presents with symptoms of the infantile form as well as dysmorphic manifestations (eg, cystic renal dysplasia).

Explanation:

Carnitine palmitoyltransferase (CPT) deficiency is a rare condition that causes muscle weakness and other symptoms. It occurs due to a problem with one or two enzymes, CPT1 or CPT2.
