Place a teaspoon of salt in a bottle cap or small cup and dampen it with a few drops of water (without dissolving it). Carefully place the wet salt and the hygrometer inside a see-through container and close tightly. You can use a zip lock bag provided it seals well and you leave some air inside as well
The answer is <span>b. wolf.

Organisms from the higher trophic levels consume organisms from the lower trophic level. In this process, energy is lost as metabolic heat. Thus, primary producers, such as sedge, contain the greatest amount of energy originally from the sunlight. The next trophic level belongs to primary consumers, such as arctic hare, that consume primary producers resulting in less energy. Similarly, arctic fox eats arctic hare, and energy is lost again. The highest trophic level is tertiary consumers such as wolf, therefore, the wolf contains the least amount of energy.
Answer:
When you exercise, the muscles you use require more energy. When exercise can be sustained, this demand is met primarily by aerobic means. Aerobic energy production in muscles results in increased gas exchange at the lungs, because more oxygen is taken in and more carbon dioxide is released.

Answer:
Vestigial structures
Explanation:
support evolution, by suggesting us that the organism changed from using structure to not using structure or using it for another purpose.
1. Answer;
-secondary structure;
Explanation;
Protein secondary structure refers to regular, repeated patterns of folding of the protein backbone. The two most common folding patterns are the alpha helix and the beta sheet. In an alpha helix, the polypeptide backbone coils around an imaginary helix axis in clockwise direction. In the beta sheet secondary structure, the polypeptide backbone is nearly fully extended. The R-groups are alternately pointed above and then below the extended backbone.
2. Answer;
- Quaternary structure
Explanation;
-Many proteins are formed from more than one polypeptide chain. The Quaternary structure describes the way in which the different subunits are packed together to form the overall structure of the protein. For example, the human hemoglobin molecule shown below is made of four subunits.
3. Answer;
-Tertiary structure
Explanation;
Tertiary structure refers to the overall folding of the entire polypeptide chain into a specific 3D shape. The tertiary structure of enzymes is often a compact, globular shape.
The tertiary structure is the structure at which polypeptide chains become functional. At this level, every protein has a specific three-dimensional shape and presents functional groups on its outer surface, allowing it to interact with other molecules, and giving it its unique function.
4. Answer;
Primary structure
Explanation;
-It is the simplest level of protein structure and is simply a sequence of amino acids in a polypeptide chain. For example, the hormone insulin has two polypeptide chains, A and B. Each chain has its own set of amino acids, assembled in a particular order. For instance, the sequence of the A chain starts with glycine at the N-terminus and ends with asparagine at the C-terminus, and is different from the sequence of the B chain.
