When and where would you expect to find the highest rate of primary productivity
Answer: Net primary productivity is the amount of gross primary productivity remaining after respiration, which is about 40 and 85 percent. Sloughs and marshes, as well as tropical rain forests, possess the highest rates of net primary productivity; deserts have the lowest.
Explanation:
I explained on the top-
The highest rate of primary productivity in terrestrial environments takes place in swamps and marshes and in tropical rainforests, and in aquatic environments it takes place in algal beds, estuaries, and reefs.
• In ecology, primary productivity refers to the rate at which conversion of energy to organic substances takes place by the photosynthetic producers that attain energy and nutrients from the sunlight, and chemosynthetic producers that attain chemical energy via oxidation.
• The majority of the energy assimilated by plants via the process of photosynthesis is not stored as organic substance, however, is utilized at the time of cellular respiration.
• In the process, the organic components like proteins, carbs, and fats are dissociated to provide energy in the form of ATP for the metabolic needs of the cells.
• The energy not utilized is stored in the tissues of the plants for future use and is known as the net primary productivity.
• The highest net primary productivity in terrestrial environments takes place in marshes and swamps and in tropical rainforests, and in aquatic environments it takes place algal beds, estuaries, and reefs.
These environments are mainly critical for the sustenance of global biological productivity.

Explanation:
The ___ of water molecules and the hydrogen bonds between water molecules explain most of water's life-supporting properties.
The ___ of water molecules to each other helps transport water from the roots to the leaves on plants.
When water warms or cools, ____ either break or form.
Thus, water absorbs or releases a great deal of ____, helping to moderate temperatures.
Water is a versatile ____.
Blood and other biological fluids are aqueous solutions with a diversity of dissolved ______.
Answer:
The polarity of water molecules and the hydrogen bonds between water molecules explain most of water's life-supporting properties.
The cohesion of water molecules to each other helps transport water from the roots to the leaves on plants.
When water warms or cools, hydrogen bonds either break or form.
Thus, water absorbs or releases a great deal of heat, helping to moderate temperatures.
Water is a versatile solvent.
Blood and other biological fluids are aqueous solutions with a diversity of dissolved solutes.
Explanation:
The sentences presented in the question above had their various spaces complemented by the words that best fit the sentence and that were capable of forming true invormations on water.
Water is a very versatile solvent as it is capable of dissolving and mixing with various substances both liquid and solid. Furthermore, water has a great capacity to absorb or release heat, which is very useful for the entire planet, as this allows water to be very efficient in regulating temperature.
Water is formed by H2O molecules, which hold these molecules together are the hydrogen bridges formed between them. Hydrogen bridges are broken through heat, which allows the water to evaporate, but at low temperatures these bridges are strengthened and new bridges can be created, which allows the water to become solid.
The properties of water are extremely important for life on the planet and for most biological processes we know about. Among these properties we can mention polarity and cohesion as one of the most important. Polarity allows water to be a polar substance, while cohesion allows water to create an attractive relationship between molecules.
Explain how different types of cells help organisms live and grow?
Different types of cells have different jobs that are necessary to keep organisms alive.
Different types of cells are only found in specific types of organisms.
Cells are necessary in order for all organisms to grow big and hunt for their food source.
Cells provide support for all organisms to be able to move.
Answer:
Different types of cells have different jobs that are necessary to keep organisms alive. And cells also give the living animal more support. They also hold the genetic information of that organism in their nucules. This is with most cells but bacteria cells do not contain nucules.
Starch is a polysaccharide used as a component of cell walls in plants.
True
False
Answer:
false
Explanation:
is type of carbohydrates
False. Starch is a polysaccharide used as an energy storage molecule in plants, but it is not a component of cell walls.
What are structural component of cell wall?Cell walls are structural components found in the outermost layers of cells in plants, fungi, and some bacteria. They provide support and protection for the cell, and are composed of a variety of different biomolecules, including cellulose, pectin, and lignin.
Starch, on the other hand, is a complex carbohydrate that is synthesized and stored in the cells of plants, particularly in the seeds, roots, and tubers. It is made up of long chains of glucose molecules and is used by plants as an energy source, particularly during times when the plant does not have access to light for photosynthesis. Starch is not a component of cell walls.

Scientists are studying the mating habits of a population of butterfly fish on a Caribbean coral reef. They discover that both the largest and smallest males get the most mates and pass on the largest number of genes to the population's offspring. The largest males get a large number of mates because they can guard the females, preventing most of the smaller males from mating. However, the very smallest males also get a large number of mates because they escape the notice of the larger males and are able to mate with the females quickly. Based on these observations, which selective force appears to be acting on male body size in this population?
Answer:
The correct answer is - Disruptive selection.
Explanation:
Disruptive selection is a mode of natural selection that exhibits that two extreme values of phenotypic traits of the population are favored by this population than the population with their intermediate values. Disruptive selection occurs when there is a fitness advantage of extreme values of phenotypic traits over more intermediate phenotypes.
In this case, the largest males mates more, due to fact that they can guard the females, than smaller males. The smallest fishes also get a high number of mates as are able to mate with the females quickly without coming to the notice of larger males.
A species is an organism that has different traits cannot______ with other organisms.
1) breed
2) evolve
3) exist
4) survive
Answer:
2 evolve

Claim: This process uses expensive fertilizers and pesticides to grow pest free crops which may be produced in excess. Explain the reasons why people would go against growing wheat this way.
Your answer: Here are 3 reasons that go against growing wheat this way.
1. The fertilizers and pesticides are expensive and cost farmers a lot which takes away from the revenue that farmers make from growing the crops in the first place.
2. Other then fertilizers and Pesticides its a lot of work as you can see on the chart throughout the year there are many things you must do too keep crops bug free and pest free this reason I'm explaining says that taking and doing all of this work for not pests/bugs is too much and not needed.
3. Fungicide Is needed a lot and incredibly expensive when you used/spray it on crops that much and point goes a lot more for large crops too.
If these reasons don't work, find factors that or counterclaims that go against this method of harvesting wheat. (This is what your supposed too do)
