Which statement best supports the RNA world hypothesis? a. DNA molecules are a precursor to self-replicating RNA molecules, which are used to build proteins. b. Early RNA molecules were able to self-replicate, which helps to explain why all organisms share the same genetic code C. Simpler self-replicating organic molecules preceded RNA and contain genetic information. d. The absence of oxygen in Earth's early atmosphere allowed for proteins to catalyze the production of new RNA molecules.
Answer:
b. Early RNA molecules were able to self-replicate, which helps to explain why all organisms share the same genetic code
Explanation:
The RNA world hypothesis is an evolutionary theory that indicates the RNA-living forms were produced first before the appearance of DNA and proteins. This hypothesis is supported by the fact that RNA is capable of reproducing on its own (like DNA), and also is able to catalyze chemical reactions (like protein enzymes). The RNA world hypothesis states that this RNA world was then followed by the evolution of ribonucleoproteins.

a virus
a human cell, a virus, and a bacterial cell
a viral particle and a bacterial cell
a human cell
a bacterial cell
Answer:
A virus
Explanation:
A virus requires a host cell to implant proteins into so that the host cell can create new virus cells. The virus essentially hijacks the cell.
All other listed cells can create new copies of their own proteins.
Cheers.
A virus does not possess the tendency to synthesize their own proteins.
• Viruses are not animals, plants, or bacteria, however, they are the quintessential parasites of the living kingdoms.
• Viruses are not living organisms as in the absence of a host cell, they cannot perform their life-sustaining activities of reproduce.
• They cannot produce their own proteins, as they are devoid of ribosomes and must utilize the ribosomes of their host cells to convert the viral mRNA into the viral proteins.
Thus, the correct answer is a virus.

Kyle wants to get rid of beetles that are in his garden, he notices in areas that in areas that have a certain type of fertilizer in the ground there are more beetles. Choose the best way Kyle can form hypothesis that could help him form an experiment to rid the beetles from his garden?
Answer: Is the fertilizer supporting the growth of beetles?
Explanation:
Here, Kyle wants to get rid of beetles in his garden but he observes that in an area where there is fertilizer there are more beetles. Thus, Kyle can frame the hypothesis that, "Is the fertilizer supporting the growth of beetles?". This hypothesis is forming the basis of experimental trials that can be done on beetles who were exposed to fertilizer and those who were not in laboratory conditions to check whether fertilizer is effective in supporting the growth of beetles. If the fertilizer is useful in supporting the growth then it should not be used in the garden.

If two trees are growing close to each other with both using light, water, and the same nutrients in the soil, the relationship is best defined as competition. the correct option would be B.
In other words, biological competition describes a form of relationship between two organisms in which both fight for the same resources that are available in limited supply.
in competition, both organisms either learn to coexist through resource partitioning or fight it to finish. Without resource partitioning, one of the organisms will have to die as a result of being outcompeted.

The spelling mistake is present in the question, so the right question is as follows:
what substance in yeast cells are responsible for Breaking Down sugar into carbon dioxide and ethyl alcohol?
Answer:
Zymase
Explanation:
Zymase is an enzyme that is responsible for breaking down sugar into carbon dioxide and ethyl alcohol in a yeast cell.

Why the characteristics of life are not always perfect guidelines for classifying living things
Answer:
Due to change in environment or evolution.
Explanation:
The characteristics of life are not always perfect guidelines used for classification of living things because these characteristics of life are different for every organism due to change in environment or due to evolution occurs with the passage of time. So for that reason we classify organisms on the basis of common ancestor and similarities in the structure not on the characteristics of life.
