. Distinguish between gross primary productivity and net primary productivity. Explain how net primary productivity affects the number of consumers in an ecosystem and on the earth. List two of the most productive ecosystems or aquatic life zones and two of the least productive ecosystems or aquatic life zones. Use the concept of net primary productivity to explain why harvesting plants from estuaries, clearing tropical forests to grow crops, and harvesting the primary producers in oceans to feed the human population are not good ideas.
Answer and Explanation:
The gross primary productivity corresponds to the sum of all the energy produced by the plants (primary producers) during the photosynthesis process. The net primary productivity, corresponds to the gross primary productivity value, even the energy value used by the plants in the metabolic processes that they present, in this way, we can conclude that the net primary productivity is the energy that is available for the living beings that consume the vegetias.
The ecosystems with the highest level of productivity are those that have a large number of vegetables with full access to the sun, in this case, we can mention forests and ecological parks. On the other hand, ecosystems with lower levels of productivity are those with a low number of plants, such as cities and areas with deforestation.
Because of our need to consume energy from net primary productivity, we are constantly harvesting vegetables and some photosynthetic water products to use in our food. However, this causes us to remove vegetables from nature and decrease the amount of gross primary productivity that ecosystems would have, and, consequently, decreasing the amount of net primary productivity that we need so much.
the study of ecology believed that living and non-living thing do not have any relationship, and living thing is independent of a non-living thing.

What to do during a flood
Explanation:
A biology student wants to conduct a study of how the amount of food affects weight gain for mice. He sets up four cages with a mouse in each cage. What are the independent variable, dependent variable, and constants? For the independent variable, what would you put in the box below for each mouse?
Answer:
dependent variable is the weight (gain) - weight depends on the food being eaten. The dependent variable "depends" on the independent variable, hence....
independent variable is amount of food
the constant is the type of food.

Explanation:
does water have cell organization
Answer:
Yes
Explanation:
Cells are composed of water, inorganic ions, and carbon-containing (organic) molecules. Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass. Consequently, the interactions between water and the other constituents of cells are of central importance in biological chemistry.

Give an example of warning coloration used in
nature.
Answer:
Warning coloration (aposematism) is effectively the "opposite" of camouflage and a special case of advertising. Its function is to make the animal, for example, a wasp or a coral snake, highly conspicuous to potential predators, so that it is noticed, remembered, and then avoided.

Why is earth interior layered??
Answer:
The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases.
Explanation:
All proteins have amino acids as their building blocks. Even though there are only 20 amino acids, there are more than a million different proteins, and each works in a unique way. Which of the following conclusions about a protein's function is best supported by this information? (4 points)
Group of answer choices
The amino acids combine in different ways to form proteins with different shapes, and this affects which molecules can bind to it, which in turn directs the protein's function.
The amino acids reproduce in different ways, and this allows them to form many different proteins, which in turn directs the protein's function.
The shape of a protein determines what amino acids it is made of and what types of reactions it can be used for, which in turn affects the protein's function.
The shape of a protein dictates when a protein will break apart into amino acids, which in turn affects the protein's function.
Answer:
The amino acids combine in different ways to form proteins with different shapes, and this affects which molecules can bind to it, which in turn directs the protein's function.
Explanation:
There are many different combinations for amino acids to bind, and all of the different combinations have very different structures.
Additionally, the unique shapes of all proteins determine the exact function that they have.
These different shapes will also affect what molecules can bind to it.

Why do cultural universals exist?
Cultural universals exist because all cultures have basic needs and they all develop common features to ensure their needs are met.
What do you mean by cultural universals?A cultural universal is an element, pattern, trait, or institution that is common to all known human cultures worldwide. Taken together, the whole body of cultural universals is known as the human condition.
There are 10 basic elements of every culture: geography, language, family, FCTS (food, clothing, transport, shelter), economics, education, politics, technology, VBR (values, beliefs, rituals), and cultural expression.
Examples of elements that may be considered cultural universals are gender roles, the incest taboo, religious and healing ritual, mythology, marriage, language, art, dance, music, cooking, games, jokes, sports, birth and death.
