Actin filaments have polarity. This means that the two ends can be identified due to structural differences. The plus end is the

Naily [24]3 years ago

Answer:

True

Explanation:

Actin is a globular protein which can polymerize to form long filaments called actin filaments. These filaments are abundant in muscle cells but are also found in other places.

While polymerizing, the new actin monomers always join the existing filament in the same orientation hence the filament becomes polar. It has a barbed end and a pointed end. Barbed end is also called plus end because monomers are added to this end five to ten times faster than the minus or pointed end. As a result, the filament overall grows in the plus end direction. Hence, the given information about actin filament is true.

Crocodiles that ignore birds cleaning their teeth instead of eating them is an example of __________.
Anettt [7]

Option (B) Habituation is the right answer.

Crocodiles that ignore birds cleaning their teeth instead of eating them is an example of habituation.

<h3>Crocodile and avian mutualism—is it real?</h3>
  • One of nature's best instances of mutualism is the interaction between a Nile crocodile and an Egyptian plover bird.
  • A crocodile will simply open his mouth and wait when he needs to floss.
  • The plover bird will involuntarily swoop down and grab meat scraps from the crocodile's gaping jaws.

<h3>Why do crocodiles develop a habit of approaching the birds that brush their teeth?</h3>
  • It is a phenomenon of evolution that when a bird used to sit in a crocodile's mouth, the crocodile didn't eat it; instead, the crocodile used to allow the bird to sit in the mouth and clean the crocodile's teeth so that they can live longer, whereas the birds could get the free food from the crocodile's mouth.
  • It is an illustration of how the two are mutually beneficial.
  • The same is true now because crocodiles have adapted to the fact that birds will clean their teeth, so rather than consuming them, they ignore the birds.
