12. Two methods of moving from place to place are represented below. The single-celled ameba moves by a process that involves the flow of cytoplasm.
Which statement is best supported by these diagrams?

(1) Both simple and complex organisms move directly by the movement of
cytoplasm.
(2) Single-celled organisms, like complex organisms, are able to move;
however, they differ in the way they carry out this activity.
(3) Cytoplasm is a fluid substance in simple cells and a solid substance in
cells of complex organisms.
(4) Cells in complex organisms function in the exact same way as cells in
simple organisms.

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

well, they made a movie about how animals lived there.

rotten tomato score 95%

note: mark other user brainliest.!

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
