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.

How do fossils provide evidence to support the theory of the evolution of earth?
Zigmanuir [339]

Answer:

Fossils provide direct evidence of evolution. They show the changes of animals from ancient organisms to present form. Fossils are the preserved remains of earth layers. There are 4 types of fossils-

Original fossils that are not very old.  e.g. teeth, skeleton, shells.

Frozen fossils

less permanent fossils

casts, molds,  and prints - wings, skin, leaves, etc.

The fossils show the adaptive radiation in horses, humans. The transition fossils form the connecting link between different groups such as fish and amphibians, reptiles and birds, etc.  

e.g. Archeopteryx is the connecting link between the reptiles and birds.

The modern horse Equus have several ancestor species, we came to know from the fossil records.

The fossil record shows the evolution of humans and their ancestors.

Serggg [28]

Answer:

Since the 2 strands of DNA are antiparallel to on another, DNA must be replicated both continuously and dis-continuously. The side of DNA that is replicated dis-continuously is done so in small parts called <u>okazaki fragments</u>.

Explanation:

OKAZAKI FRAGMENTS -  Okazaki fragments are short DNA nucleotide sequences (roughly 150 to 200 base pairs in eukaryotes) that are synthesized in a non-linear fashion and then linked together by the enzyme DNA ligase to form the lagging strand during DNA replication.    They shape short double-stranded DNA sections when combined with the lagging template strand.

The primosome initiates Okazaki fragments by generating a new RNA primer. To restart DNA synthesis, the DNA clamp loader releases the lagging strand from the sliding clamp and reattaches the clamp to the new RNA primer. DNA polymerase III will then synthesize the segment of DNA.

Reiji Okazaki, Tsuneko Okazaki, and their colleagues first found Okazaki fragments in 1968 while researching bacteriophage DNA replication in E. coli.
