Viruses are generally considered to be nonliving. Should viroids and prions also be viewed as nonliving? Why or why not?
katen-ka-za [31]
Yes they should be viewed as nonliving. Because viroids are just like viruses without protein coats. They are similar to viruses excepte the protein coat. And prions are like malfunctioned proteins. They cause diseases too but they are non-living too. Because they too, don't have any metabolics reactions.

Vaccination _____.
Luden [163]

Answer:

involves injecting the body with specific medication

Explanation:

Vaccination is a versatile and effective methodology for preventing diseases caused by exposure to harmful bacterial and viral infectious agents. Literally, vaccination refers to the administration of medical preparations that help the body to produce immunity against infectious diseases. Vaccines are used to prevent outbreaks caused by infectious diseases. Even under optimal conditions, vaccination is not always effective in preventing disease transmission, because the immune system of each organism may react in a different manner to the same vaccination (even to the same dose). However, vaccination is always encouraged to prevent the spread of infectious diseases. Although there are many vaccines that target age groups, there are others that can be applied to different ages.

What type of behavior is a bird song, learned or innate?
SashulF [63]

Answer:

The tendency of the bird or the inclination to sing is innate in birds, however, the song, which is sung is learned. There exists an innate tendency to sing a song whether the bird is in seclusion or not. The birds possess sensitive/critical periods when they can produce memories of the songs they learn. The anterior forebrain pathway or the anterior vocal pathway is the template for learning a song by the bird.

Upon centrifugation, particles sediment at different rates due to their physical properties. Tropomyosin is a rod-shaped protein
polet [3.4K]

Answer:

Elongated shape

Explanation:

Centrifugation separates molecules on the basis of angular motion.

Due to spherical shape, the value of 'f' is lesser for a spherical protien than the rod shaped one.

Hence the sedimentation coefficient for an elongated protien is 2.6S while htat of a spherical protien is 4.31S.

Hence its elongated shape results in slow centrifugation.

Some of the important principles of centrifugation are as follows :

  • The greater the mass, the more is the sedimentation rate i-e the one with greater mass will move down more rapidly as compared to the one with les mass.
  • Shape of particles also effect it, the rounder the particle, the lower frictional coeeficient.
  • Density of particles
  • Density of fluid
