What do all living things have in common? All have cells with a nucleus. All have a genetic code. All are made of two or more cells. All can perform photosynthesis.
Answers
Living beings are organisms that can respire, respond, grow, reproduce, and are made of cells. All living things have a genetic code. Thus, option B is correct.
What is a genetic code?A genetic code is a sequence of proteins and nucleic acids that act as a hereditary molecule that transfers the traits and characteristics to the progeny.
The code can be in the form of DNA or RNA and provides information about the genotype of the organisms that were passed from their ancestors.
The genetic code is in the form of triplets and is a universal system that codes for the same proteins in all organisms. It consists of the nitrogenous bases that through translation make the amino acids.
Therefore, option B. all living organisms have a genetic code.

Answer:
Earth cooled
Explanation:
Here are all the answers for that quick check:
1. Which option orders the events chronologically, from earliest to latest.
Answer: Single-celled organisms increase atmospheric methane concentrations. Photosynthesizing bacteria release oxygen into the sea. Oxygen concentrations increase in the atmosphere. Many new animal species evolve.
2. Which forms of life were dominant in the Mesozoic era?
Answer: Reptiles
3. How did the success of photosynthetic bacteria change Earth’s atmosphere?
Answer: increased oxygen concentration
4. How did reduced methane concentrations in the atmosphere affect Earth?
Answer: Earth cooled.
5. Which characteristic defines the Paleozoic era?
Answer: Animals with shells and hard parts were dominant for the first time.
You're welcome.
Answer:
Earth cooled.
Explanation:
The reduced methane concentrations in the atmosphere affect Earth :
Particles of gas and dust released into the atmosphere during a volcanic eruption affect the climate. Most of the particles emitted by the volcano cool the planet by blocking incoming solar radiation. The cooling effect can last from months to years, depending on the nature of the eruption.Therefore, the Earth is cooled.

An island experiences a decade long drought which causes a die off of several plant species. The only plants that survive have extremely small seeds with less nutritional value. Parrots which live on the island and eat seeds are more likely to survive and successfully reproduce if they are smaller since smaller body size requires less calories. Over the course of the decade, the average body size of the parrot population decreases. Which of the following statements below are correct?
a. The parrot population has evolved.
b. This is an example of genetic drift.

If a DNA molecule had a total of 1000 nucleotides and 200 of these are adenines, what would be the total number of pyrimidines in this molecule?
Answers
If a DNA molecule had a total of 1000 nucleotides and 200 of these are adenines, then the total number of pyrimidines is 500. Adenines (A) are purine bases.
DNA is a double helix molecule composed of two long chains of nucleotides that are held together by hydrogen bonds.
In DNA, there are four types of nucleotides, each containing one different nitrogenous base: Adenine (A), Guanine (G), Cytosine (C) and Thymine (T).
Adenine (A) and guanine (G) are purines, whereas cytosine (C), thymine (T), are pyrimidines.
According to the base pair rules, Adenine always pairs with Thymine, whereas Guanine pairs with Cytosine.
In this case, the number of A + T is equal to 400 (200 + 200) and the number of G + C is 600 (300 + 300), thereby the number of pyrimidines or C + T is equal to 500 (200 + 300).
