1. The right answer is C) carbohydrate
Lipids is not a correct answer because some like phospholipids can contain phosphorus.
IUPAC defines carbohydrates as a class of organic compounds containing a carbonyl group (aldehyde or ketone) and at least two hydroxyl groups (-OH).
They are so called because their chemical formula was based on the model Cn (H2O) p.
2. The right answer is B) protein
The structure of proteins is the amino acid composition and the three-dimensional conformation of proteins. It describes the relative position of the different atoms that make up a given protein.
Among the amino acids, 19 amino acids contain only four chemical elements: carbon, hydrogen, oxygen and nitrogen; two amino acids additionally contain a sulfur atom, and a rather rare amino acid contains a selenium atom.
3. The right answer is D) Watson and Crick
While many biologists seek to understand how DNA forms copies of itself, James Watson and Francis Crick will be interested in the shape of DNA.
At a congress in Naples, Maurice Wilkins presents the first X-ray photographs of DNA. Despite the very limited clarity of the photo, it is the regular structure of DNA that challenges James Watson ...
The photograph of Rosalind Franklin's X-ray DNA shows that this macromolecule is cross-shaped. After a year and a half of team research, Crick and Watson finally understand that this form of cross reveals that DNA is a double helix.

Which characteristic of life best describes the process of photosynthesis?
For this question, what you need to pay attention to is what the process of photosynthesis does for the plant, once you know that, the answer is pretty much over.
Being brief, the photosynthesis uses the light to create energy, and this energy is used to maintain the metabolism working in a way that the plant won't miss this energy. So, this process creates a molecule called glucose, that's the energy for the plant, and it's used for many functions within it. For example, plants use glucose to make cellulose, the main part of their cell wall. Starch is too, made by using glucose, and it's used as a reservation of energy for the plant.

why would a fish that lives in the bathypelagic zone lack a swim bladder,and what adaptations would help it maintain neutral buoyancy?
A fish in the bathypelagic zone may lack a swim bladder due to the high pressure that makes it impractical; instead, they have adaptations like less bone mass, high lipid levels, specialized tissues, and gelatinous tissue to maintain neutral buoyancy.
A fish that lives in the bathypelagic zone might lack a swim bladder because the high pressure at deep sea levels would make it difficult to maintain a gas-filled organ for buoyancy control. Instead, these fish have other adaptations that help maintain neutral buoyancy. This includes adaptations such as minimal bone mass, increased levels of lipids that are less dense than water, and specialized tissues that can absorb gases from the water directly, minimizing the need for a swim bladder. They may also have a more watery, gelatinous tissue that provides buoyancy without the necessity of a gas-filled organ.
While swim bladders are used by many bony fishes to control their buoyancy, allowing them to maintain their position in the water column without expending energy, not all fish possess swim bladders. In the deep sea, conditions such as extreme pressure make swim bladders less functional or too costly in terms of biological energy to maintain. Therefore, fish in these environments have evolved alternative strategies to regulate their buoyancy and adapt to their hypertonic surroundings.
These adaptations not only help the fish conserve energy but also avoid predation and increase their efficiency in capturing prey, which is scarce in such deep zones of the ocean.

What would happen to the size of the herbivore population if the producer population decreased?
Answer:
If the producer population decreased, the size of the hervibores population will diminish.
Explanation:
Producer population refers to autotrophic organisms (plants for example). These organisms are the nutrition source for primary consumers (like hervibores). So if the nutrition source decreased, the population size of hervibores will decreased too.
Manuel's teacher asked the class to make a wet mount slide of their cheek cells. Manuel made his slide and placed it on the microscope stage. Then he got ready to view his cheek cells by following these procedures. 1. Looking through the eyepiece, Manuel adjusted the diaphragm so field of vision was lit. 2. Manuel looked at the stage from the side and lowered the body tube so the high power objective was almost touching the slide. 3. Looking into the eyepiece, he very slowly turned the coarse adjustment to bring the cells into focus. What suggestion would you make to Manuel to CORRECTLY use the microscope to view his cheek cells?
