Answer:
A function that is not characteristic of lipids is forming the exoskeleton of insects.
Explanation:
The exoskeleton is a rigid external structure that provides support and protection to animals such as insects.
The structure of exoskeletons is formed, especially in insects, by chitin. Chitin in turn is made up of N-acetyl-glucosamine, which when polymerized forms the hard and resistant layer that forms the external cover of the insects. Exoskeletons do not contain lipids in their composition.
The other options are correct with respect to the function of the lipids:
B. Hydroxy fatty acid form the waxy layer that covers the leaves of the plants.
C. Lipids are a reserve energy source, stored in the fatty cells.
D. Phospholipids are the main component of cell membranes.

Which of the following is true:
- Since the active site has a specific shape it can only fit one substrate.
- The active site can fit any type of substrate.
- Nothing can fit or bond with the active site of an enzyme.
Answer: Since the active site has a specific shape it can only fit one substrate.
Explanation: I took one for the team on Ed puzzle.
Since the active site has a specific shape it can only fit one substrate. The correct option is A.
What is active site of enzyme?The active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction in biology and biochemistry.
The active site is made up of amino acid residues that form temporary bonds with the substrate (binding site) and residues that catalyze the substrate's reaction (catalytic site).
The active site of an enzyme is the specific region of the enzyme where a substrate binds and catalysis or chemical reaction occurs.
It is a protein structural element that determines whether the protein is functional when subjected to an enzyme reaction.
A holoenzyme is a fully active enzyme that is made up of a protein portion (apoenzyme) and a cofactor.
Thus, the correct option is A.

Hundreds of years ago, a volcanic eruption killed many plants and animals on a tropical island. Today, the island looks much as it did before the eruption. Why is this true? Destroyed ecosystems always return to their exact original state. Altered ecosystems only regain stability from the development of grasses. Geographic barriers prevent the migration of animals to island habitats. Destroyed environments can recover through ecological succession.
Answer:
Destroyed environments can recover through ecological succession.
Explanation:
Ecological succession describes a progressive change in the species in an ecological community over time.
This can happen after some disturbance such as a fire, earthquake, or volcanic eruption. It can mean that a e can return to the state it was before the event.

What is the initial source of the energy in all food webs and food chains? Explain please
Answer:
The sun
Explanation:
The sun provides the light energy that plants need in order to produce glucose the animals gain after eating the plants or the animals that ate the plants.
The initial and ultimate source of the energy in all types of food webs and food chains is the Sun.
What is the primary source of energy?The Sun is the major source of energy for living organisms and the ecosystems of which they are a part on the Earth. Producers are the organisms of the food chain which produce energy such as plants, algae, and cyanobacteria. These organisms use the energy from sunlight to make organic matter from that of carbon dioxide and water molecules. This establishes the beginning of energy flow through almost all the food webs.
The light which is coming from the sun allows the green plants that is the producers to manufacture chemical energy which fuels all the cellular functions. In turn once the plants are eaten, this chemical energy and nutrients are transferred to the consumers and to other higher organisms.

Which of these is a benefit of naturally occurring forest fires? A) They spread the seeds of some trees. B) They allow the forest to become dense. C) They cause the forest canopy to thicken. Eliminate D) They allow ladder trees to entwine with large trees.
Answer:
A
Explanation:
Here, we want to pick which of the options is a correct answer to being the benefit of naturally occurring forest fires.
The correct answer is that they help to spread the seeds of some trees.
Naturally occurring forest fires ravages the forest and thus work with wind force. They proceed through the entirety of the forest from the point in which they start.
By moving from a particular point in the forest to another point in the forest, they allow for the process of mass movement to naturally occur.
By translocation from one point to another, they take the seeds alongside with them and thus allows for the dispersal of these seeds through the forest

Individual organisms making up a population may be evenly distributed, randomly distributed with no discernible distribution pattern or grouped together. These distribution patterns are called uniform, random, and clumped.
Distribution patterns (also known as species dispersion patterns) refer to the distribution of individuals within a population at any point in time.
Dispersion is the process of a group of living things expanding the area or range in which they live. Dispersion occurs when individual organisms move from the area that they occupied before, or where they were born, to new areas.
Uniform means the population is uniformly distributed, random means the population is randomly distributed, and clustered means the population is clustered.
The labeled diagram showing the population distribution patterns is given below.

Cells can best be described as
Cells can best be described as the fundamental units of life. They are the building blocks of all living organisms, including plants, animals, and even microorganisms.
Here are some key characteristics that describe cells:
1. Structure: Cells have a defined structure with a plasma membrane that separates the internal components of the cell from the external environment. Inside the cell, there is a variety of organelles, such as the nucleus, mitochondria, and ribosomes, each playing a specific role in cell function.
2. Function: Cells carry out various functions necessary for life. They perform metabolic processes, such as respiration, photosynthesis, and protein synthesis. Cells also maintain homeostasis, which involves regulating internal conditions to keep the cell functioning optimally.
3. Reproduction: Cells have the ability to reproduce. They can divide and create new cells through processes like mitosis and meiosis. This ensures the growth, development, and repair of tissues and organs.
4. Genetic Material: Cells contain genetic material in the form of DNA (deoxyribonucleic acid). DNA carries the instructions for cellular activities and determines the characteristics of an organism. It is organized into genes, which are passed on from one generation to the next.
5. Specialization: Cells can be specialized to perform specific functions within an organism. For example, muscle cells contract to enable movement, while nerve cells transmit electrical signals for communication. This specialization allows multicellular organisms to have different cell types that work together to maintain overall function.
Overall, cells are the basic structural and functional units of life. They are responsible for all the processes necessary for an organism's survival and are crucial for maintaining life's complexity and diversity.
