Answer:
C. Africa and South America were once joined into one continent.
Explanation:
Mesosaurus is an extinct genus of reptile, also called middle Lizard. It was significant in providing for the theory of continental drift (which explains that is the theory that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed ) because its remains were found southwest coast of Africa and south east coast of south America. This is because Mesosaurus is a coastal animal, and it seems very unlikely that the animals crossed the Atlantic ocean. Thus indicating the two continent might really have been joined together in the past.

Explanation:
Pulsar is also called as<u> neutron stars or white dwarfs.</u> These are formed after the supernova explosion. Their mass is higher than a normal star. And the most different thing we find in pulsar is that, in a pulsar the proton and electrons combine themselves to form a neutron. That's why this is also called as neutron star. After neutron or white dwarf the star goes to the black dwarf stage.
Remember when the core of the iron becomes iron rich that time it cannot sustain further nucleo synthesis process, that's why it goes for a supernova explosion. Which results the formation of neutron star or white dwarf, followed by black dwarf or black hole.
Answer:
The correct answer will be-
Case I- option-B
Case-II-option-B
Explanation:
A scientific method is the best procedural approach to explain the natural phenomenon. The method includes various steps which begin with the making the observation. The observation leads to the asking the scientific questions which could be answered by proposing a hypothesis.
The hypothesis must be tested through experiments which could prove and disprove the hypothesis and can answer the natural phenomenon.
<u>Case-I</u>
In the given situation of the question in which a person notices or observes the fields of grass and grass and native flower. Since the researcher notices the fields, they are performing the first step of the method that is "making an observation" and thus Option-B is the correct answer.
<u>Case-II</u>
In the situation, which discusses the number of birds in the fields shows the "dependent variables". The dependent variable is the parameter which is studied in the experiments. Since in the given conditions the number of birds is being studied, therefore, Option-B is the correct answer.
