Answer:
A hypothesis that is not possible, or has less strength, to explain how life arose on Earth is that it originated from cells that were delivered by meteorites from outer space (option D).
Explanation:
Although it is a hypothesis that has scientific foundations to be considered, the origin of life coming from organic molecules or cells from space -called Panspermia- has not been completely proven because:
- It provides information on the origin of cells or organic matter, but it doesn't specify how life was formed from them.
- It does not resolve the question of how a cell could withstand a journey through space or endure the high temperatures when a meteorite entered the primitive atmosphere.
These arguments make the hypothesis of the arrival of the first cells from outer space the least accepted today.

Answer:
<em>The statement that is incorrect is :</em>
<em>Robert wanted to see if his theory was true that cigarette smoke will influence web-building in spiders.</em>
Explanation:
A theory can be described as a descriptive explanation of a phenomenon which is supported by valid experiments and careful examination of facts. As Robert, has not conducted any experiments nor has proved his study with reference to facts, hence it cannot be considered as a theory.
Robert wanted to see if his observation was true that cigarette smoke will influence web-building in spiders will be the correct statement that could be used.
The answer will be B. It is common sense
Answer:
Switch from lysogenic to lytic growth.
Explanation:
Lysogenic induction is a term widely used in virology to describe the passage of viruses from the lysogenic cycle to the lytic cycle.
As you may already know, viruses are obligatory parasites and that is why they need to infect a cell in order to reproduce and that is exactly what the lysogenic and lytic cycles are related to.
The lysogenic cycle refers to the situation where the virus cannot reproduce immediately upon entering the cell. For reproduction to occur, it is necessary for the virus to establish a combination between its genetic conditions and the genetic conditions of the cell, while the virus cannot establish this, the cell can follow its cycle in a normal way.
In the lytic cycle, in turn, the virus can reproduce more immediately, because it can quickly assume the functions of the cell that completely loses its control over its cycle. In the lytic cycle, the virus inserts its genetic material into the cell and makes it work to reproduce it.
