The correct answer is Option (B) Habituation.
Crocodiles ignore the birds which clean their teeth instead of eating them. This is an example of habituation.
Why do crocodiles show habituation toward the birds which clean their teeth?It's an evolutionary phenomenon 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 teeth of the crocodile so that they can alive longer, whereas the birds could get the free food from the crocodile’s mouth. It is an example of the symbiotic relationship between the two.
So, the same is the case today, crocodiles are habituated to the fact that the birds will clean their teeth so instead of eating them, these birds are being ignored by the crocodiles.

According to the cell theory, which describes cells?
All organisms are composed of multiple cells.
All cells have the same structure and function.
Cells are found in everything on Earth.
All living cells come from other living cells.
Answer:
All living cells come from other living cells.
Explanation:
"All organisms are composed of multiple cells" can't be right, due to the fact that single-celled organisms do exist. "All cells have the same structure and function" is blatantly untrue, otherwise we wouldn't exist right now. We'd all be bacteria. "Cells are found in everything on Earth" is also not correct- there are extreme climates where even the hardiest organisms can't survive, like pits of magma in the recesses of the Earth. That leaves us with "All living cells come from other living cells", which is indeed true, all cells duplicate via a process called mitosis, and in order for replication to happen, there needs to be a parent cell in order to duplicate DNA.

If the production of cyclins is halted during the cell cycle, the cell would remain in the same phase (e.g.- G2) and would not be able to enter into mitosis.
The cyclins are the most important core cell cycle regulators. They are a group of related proteins, as well as there are four basic types found in humans and most other eukaryotes.
Each of the cyclin is connected with a particular phase, transition, or a set of phases in the cell cycle, which helps in driving the events of that particular phase or period.

Capsules can hinder host cell phagocytosis, stop complement-mediated lysis, and stop bacterial desiccation.Typically hear about three main categories of germs: bacteria, viruses, and fungus.Since most capsules inhibit water loss, they may aid in the bacterium's ability to avoid desiccation. A bacterial cell can be shielded by a capsule from white blood cells' digestion and obliteration.By inhibiting pathogen-associated molecular patterns or from binding to endocytic pattern-recognition receptors on the surface of the phagocytes, capsules can avoid unenhanced adhesion.

Bacteria that release a toxin that forms a pore in red blood cells leading to hemolysis are using an alpha toxin to gain access to the nutrients inside the erythrocyte.
The best characterized and most potent membrane-damaging toxin of Staphylococcus aureus is α-toxin. It is expressed as a monomer that binds to the membrane of susceptible cells.
In humans, platelets and monocytes are specifically sensitive to α-toxin. They bear high affinity sites which allow the toxin to bind at concentrations that are physiologically relevant. A complex series of secondary reactions follow, leading to the release of eicosanoids and cytokines which in turn trigger the production of inflammatory mediators. These events cause the symptoms of septic shock that occur during severe infections caused by S. aureus.

As electrons fall from photosystem ii to photosystem i, the cytochrome complex uses the energy to pump ions. this builds a proton gradient that is used in chemiosmosis to produce what molecule?
As electrons fall from photosystem ii to photosystem i, the cytochrome complex uses the energy to pump ions. this builds a proton gradient that is used in chemiosmosis to produce ATP.
In plants and cyanobacteria, a two-step mechanism known as noncyclic photophosphorylation results in the direct production of ATP and NADPH during photosynthesis. High-energy electrons exiting photosystem II are used in the noncyclic photophosphorylation process just outlined to produce ATP, which is then transferred to photosystem I to promote the creation of NADPH.
For every pair of electrons that move from H2O to NADP+ to create a molecule of NADPH, this results in the production of slightly more than one molecule of ATP.

In the DNA isolation process, ice cold 95% ethanol is used to break down the protein complexes and allow the DNA molecules to easily precipitate.
What is separation and isolation of DNA fragments?
The cutting of DNA by restriction endonucleases results in the fragments of DNA. These fragments can be separated by a technique known as gel electrophoresis.Since, DNA fragments are negatively charged molecules they can be separated by forcing them to move towards the anode under an electric field through a medium/matrix.The most commonly used matrix is agarose which is a natural polymer extracted from sea weeds.The DNA fragments separate (resolve) according to their size through sieving effect provided by the agarose gel. Hence, the smaller the fragment size, the farther it moves.The separated DNA fragments can be visualised only after staining the DNA with a compound known as ethidium bromide followed by exposure to UV radiation (you cannot see pure DNA fragments in the visible light and without staining). We can see bright orange coloured bands of DNA in a ethidium bromide stained gel exposed to UV light.The separated bands of DNA are cut out from the agarose gel and extracted from the gel piece. This step is known as elution.The DNA fragments purified in this way are used in constructing recombinant DNA by joining them with cloning vectors.To learn more about DNA isolation process: brainly.com/question/18316109
