Answer: e) gain of function in disc B of some of the structures usually seen in disc A
Explanation:
it can be inferred that having a gene B and adding a gene A, it can develop forms of both patterns, since it is known that gene A does not interfere in the formation of B, which acts independently to generate its genetic characteristics Thus, the function of B will remain the same and genetic dysregulation will not occur.
Answer:
If a species has a number of chromosomes 2n = 18, then its somatic cells have 16 autosomes.
Explanation:
Somatic cells are diploid, that is, they have the complete chromosomal charge, and it is represented as 2n. In organisms with sexual reproduction the chromosomes are divided into autosomes and sex chromosomes, which are 2.
<u>If a species has a number 2n = 18, it means that its somatic cells have 18 chromosomes, of which 16 are autosomes</u> and 2 are sex chromosomes. Autosomes contain the structural and functional characteristics of an individual, while the sex chromosomes determine sex.
Answer:
Prions causes abnormal folding of the prion proteins in the brain.
Explanation:
Prions are the abnormal infectious agents composed only of the proteins and no nucleic acids. The prions cause several neurodegenerative diseases in the humans as well as the mammals.
The prions cause the cow mad disease in the cows by affecting the brain of the cow as the prions act on the prion proteins present in the brain only and change their conformation. This leads to the degeneration of the neurons and causes tiny pores in the brain giving sponge-like appearance.
This slows down the mental activity and thus ultimately leads to the death of the cow.
Its so small can u make it bigger?
Depends on what you consider "Large". Usually what we consider large amounts, would just make us urinate as it is not water that we need and so would filter it out.
However if you were to say ingest such an amount that it has become toxic, you run the risk of a very dangerous condition called Hyperhydration or Water Intoxication. Under most normal circumstances water and salt are present in cells and the blood. If you remember; water travels through osmosis, or from a higher to lower concentration across a semipermeable membrane. Salt helps to maintain the concentration. However if you drink so much water that it would be considered "toxic" the water that would eventually find it's way into your blood would try to balance with the cells, which begin to absorb so much water that they swell, therefore causing swelling to the body's tissues and organs.
The dangerous bit is when the brain begins to swell. Symptoms such as <span>headache, personality changes, changes in behavior, confusion, irritability, and drowsiness. These are sometimes followed by difficulty breathing during exertion, muscle weakness & pain, twitching, or cramping, nausea, vomiting, and thirst, begin to manifest. The dangerous bit is when the swelling compresses the brain to such a degree it crushes the brain stem and herniates through the foramen magnum. The brain stem or Medulla Oblangata is responsible for the processes keeping you alive, and if it's crushed your heart rate, blood pressure, and breathing will become compromised, a recognizable feature we EMT's look out for called Cushing's Triad. This is mostly irreversible and will lead to neurogenic shock, coma, and then death.
The important lesson, is to always take thing in moderation.</span>
