The correct answer that would best complete the given statement above would be the first option. <span>A hawk maintains a constant internal temperature in both the heat of the day and the cool of night this is called endothermy. By definition, endothermy means that it is the physiological generation and regulation of body temperature by means of metabolism. Hope this answer helps.</span>
Nucleolus is not connected to the nucleus via nuclear pores.
<span>Nuclear pores are protein complexes that cross double membrane of the nucleus and allow the transport of molecules across the nuclear envelope (double membrane): from the nucleus to the cytoplasm (RNA and ribosomal proteins) and into the nucleus (proteins, carbohydrates, signalling molecules and lipids).</span>
Answer:
Prions are abnormally shaped proteins that cause spongiform encephalopathies. (Ans C)
Explanation:
Prions : Prions are proteinaceous infectious particle or misfolded proteins with the ability to transmit their misfolded shape into normal shape protein. They are also responsible for some neurodegenerative diseases in mammals. They can affect both animals as well as humans.
Prion disease occurs when normal prion protein (present on the surface of many cells) becomes clump (abnormal) in the brain. This accumulation of abnormal protein in the brain can cause disease.
Spongiform encephalopathies also called prion disease. Spongiform encephalopathies affect the nervous system and brain of animals & humans. It is caused by a degeneration of brain tissues giving it a spongy appearance.
Answer:
El genoma humano es el conjunto completo de secuencias de ácido nucleico para humanos, codificado como ADN dentro de los 23 pares de cromosomas en los núcleos celulares y en una pequeña molécula de ADN que se encuentra dentro de las mitocondrias individuales. Estos generalmente se tratan por separado como el genoma nuclear y el genoma mitocondrial.
