Answer:

Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration. The concept of diffusion is widely used in many fields, including physics, chemistry, biology, sociology, economics, and finance.

A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.

Fish farming involves raising a variety of aquatic animals, such as fish, mollusks and shrimps in an enclosure such as a tank or pond. With the surge in demand for healthy animal protein the  demand for fish and fish products is on the rise. Fish farms have the potential to produce fish for home consumption at about $0.90/lb which is a considerable saving when compared to supermarket prices of over $2.00/lb.

The first step for fish farming is to determine what you are going to do with your full-grown fish. You need to know the purpose, whether you are going to keep fish as a pet or for fish meat. This will decide a lot of things like the space requirements, equipment and capital requirements. If you intend to keep fish as a pet for showcase then a small tank or a backyard small fish farm is sufficient. If you intend to put a small fish farm with one or two ponds then also with a little business mindset you can market 1000 to 2000 lb of fish.  

This will also require you to set up a business entity and have a business mindset.The costs associated with raising different types of fish varies because different fish need certain temperature water to live. The type of fish also decides the requirement of equipment and the feed cost. There are lots of laws about raising fish and animals, and even more, stringent laws related to raising animals that are going to be consumed as food.

Before starting fish farms or fish hatchery of any size or type it is advisable to check local laws and the need of permits  to do so in your area.Normally you will get a license to operate your fish farm for a year which will be renewable. You need to submit the following documents to apply for the license:

Filled in application form

Sketch or aerial map of the facility layout, including dimensions

Copy of fish health certificate

Copy of stocking permit

Letter of a written permission from the landowner (in case if you are not the landowner)

Answer:

it will be 10Hz ,because number of waves per second is 10 so we divide with 1second

The wave frequency of a wave which is passing by 10 waves over a time period of 1 second will be 10 Hertz (Hz).

Wave frequency can be defined as the number of waves which are passing through a fixed point in a given amount of time period. The SI unit for the wave frequency is the hertz (Hz), where 1 hertz is equal to 1 wave which is passing through a fixed point in the time period of 1 second. A higher-frequency wave has generally more energy than a lower-frequency wave with the same magnitude of amplitude.

The wave frequency of a wave which is counted to be 10 waves passing through a point in a time period of 1 second will be 10 Hertz (Hz).

Answer:

Citrate Synthase facilitates the formation of citrate by deprotonating Acetyl CoA and by protonating the carbonyl oxygen of oxaloacetate

Explanation:

Citrate synthase is a key enzyme in the citric acid cycle that functions to catalyze the formation of citrate from oxaloacetate and acetyl-CoA: acetyl-CoA + oxaloacetate + H2O >> citrate + CoA-SH (Coenzyme A ). This enzyme contains three amino acids at its active site that work together to catalyze the conversion of acetyl-CoA and oxaloacetate into citrate. This active site acts by abstracting (deprotonating) a proton from the alpha carbon of Acetyl CoA which serves as the nucleophile. Subsequently, the active site of the enzyme also protonates the carbonyl oxygen of oxaloacetate, which then suffers nucleophilic attack and thereby facilitating nucleophilic substitution reaction.

Answer:

1.Buccal pumping is "breathing with one's cheeks": a method of ventilation used in respiration in which the animal moves the floor of its mouth in a rhythmic manner that is externally apparent.

2.Cutaneous respiration, or cutaneous gas exchange, is a form of respiration in which gas exchange occurs across the skin or outer integument of an organism rather than gills or lungs.

3.Pulmonary ventilation is commonly referred to as breathing. It is the process of air flowing into the lungs during inspiration (inhalation) and out of the lungs during expiration (exhalation.

Hello. You did not present the answer options, which makes it difficult for you to receive a specific answer. However, I will try to help you in the best possible way.

One of the most common evidences that a paramecium is maintaining homeostasis is the pumping of water from the vacuoles present in its body.

The paramecium is a protozoan that lives in aquatic environments, mainly those composed of fresh water. The problem with this environment is that water is able to enter the paramecium organism in large quantities and this can promote the disruption of the organism through lysis of the cell. In this case, homeostasis must act quickly and pump water out of the body, through the cell vacuole.

Homeostasis is a regulatory system of the organism, which must promote the balance of the organism, whenever any external or internal factor tries to harm this balance.

Answer:

Environmental change

Explanation:

A species that has little genetic variation cannot evolve (change) in response to variable environmental conditions because genetic variation is the raw material on which natural selection operates to select individuals. Adaptation to changing environmental conditions only can occur when there is variation (either genetic or phenotypic variation). In consequence, a species with low genetic variation is at a high risk of extinction, especially in challenging environments.

Explanation:

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

Am I supposed to answer #8?

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows.

Moreover, 7 major ecosystems are forest ecosystem, grassland ecosystem, tundra ecosystem, desert ecosystem, freshwater ecosystem, and marine ecosystem.

Hence, healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes. They are at the foundation of all civilization and sustain our economies.

Answer:

reactants = carbon dioxide & water

energy source = light

waste product = oxygen

primary energy = glucose

Explanation:

The energy source is light, reactants are carbon dioxide and water, the waste product is oxygen and primary energy is glucose.

The sustainability of the significant number of life on Earth depends on photosynthesis. It is how almost all of the energy in the biosphere is made accessible to living beings.

All higher living forms on Earth consume photosynthetic organisms directly or indirectly since they are the primary producers that serve as the foundation of the planet's food webs.

Additionally, photosynthesis is responsible for producing virtually all of the oxygen in the atmosphere. The majority of creatures would vanish, there might soon be little food or other organic stuff on Earth, and the atmosphere would eventually be almost barren of gaseous oxygen if photosynthesis stopped.

Commonly used notation for photosynthesis is: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂. This indicates that the reactants, six carbon dioxide molecules, and six water molecules, are transformed into a sugar molecule and six oxygen molecules, the products, by light energy being absorbed by chlorophyll (implied by the arrow).

The creature consumes the sugar, and as a byproduct, oxygen is produced.

Therefore, the energy source is light, reactants are carbon dioxide and water, the waste product is oxygen and the primary energy is glucose.
