False. A threat is a possible danger. Vulnerability is a weakness.
Answer: 2.6 x 10^13 m/day
Work:
There’s 86,490 sec per day, so
(3.0 x 10^8 m/s)(86,400 s/1 day) = 2.6 x 10^13 m/day
Francesco Redi performed his experiment against the theory of spontaneous generation. In his experiment, he takes one glass jar and a piece of flesh and analyzes them in three different situations.
<h3>Why did Francesco Redi perform his glass jar experiment?</h3>
Francesco Redi performed his glass jar experiment in order to illustrate the evidence against the theory of spontaneous generation.
He demonstrate that dead maggots or flies would not generate new flies when positioned on rotting flesh in a sealed jar, whereas live maggots or flies would have the capability to grow some eggs of maggots.
This experiment discredited both the presence of some essential components in once-living organisms and the requirement of fresh air to induce living life.
The complete question is as follows:
Which choice best summarizes the outcome of Redi‘s experiment?
- Evidence for the theory of spontaneous generation.
- Evidence against the theory of spontaneous generation.
- Evidence for the theory of special creation.
- Evidence for the theory of the origin of life.
Therefore, the correct option is B, i.e. Evidence against the theory of spontaneous generation.

The DNA molecule is composed of two long complementary chains of nucleotides. The complementary DNA sequence of CGTA is GCAT.
The DNA molecule is composed of two antiparallel strands of nucleotides linked together by hydrogen bonds.
In DNA, there are four types of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytocine and Thymine).
In RNA, Thymine bases are replaced by Uracil bases.
According to the base pair rules, Adenine (A) always pairs with Thymine (T), whereas Cytosine (C) always pairs with Guanine (G).
In conclusion, the complementary DNA sequence of CGTA is GCAT.
