Answer:
4
Explanation:
Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.
The water lilies may adapt to needing less water, both to drink and to live. The flowers will try to adjust to their new habitat by needing less water as there is less available.
In this experiment, researchers compared how fast the junco populations adapted.
<h3>What is the focus of the study?</h3>
This study focuses on the adaption process of Juncos (a specific bird population) in urban environments and how they behave in terms of stress and boldness behavior (interest in exploring unknown areas).
<h3>How did the study work?</h3>
In this study, scientists compared the behavior of a population of birds in an urban area with the behavior of another population of birds that lived in a novel urban area to determine the adaptation process of the second population.
Note: This question is incomplete because the information about the study is missing; here is the name of the possible study: Boldness behavior and stress physiology in a novel urban environment suggest rapid correlated evolutionary adaptation

After the genetically modified plasmids are inserted into bacteria; the bacteria make proteins from the inserted modified genes.
Explanations;
Plasmids are small, circular strands of DNA that are present in bacterial cells and are capable of self-replication. To add pieces of foreign DNA to bacteria, scientists first package the DNA of interest within the plasmid, and then induce the bacteria to take up the vector. This in turn makes the host bacterium a new, genetically modified organism. Once inside the bacteria, foreign proteins can be made within the bacteria, that is; if the introduced DNA is a gene that encodes a protein, then gene's protein product can be studied by expressing it in the bacteria.
