why is the study of fish and fish farming important in the study of animal science?
Answer:
Such physiological research will offer a wealth of information that can help in fish survival and management. This include how fish respond to and withstand a variety of environmental factors, as well as how fish bodies and internal processes evolve over time (including smoltification and reproduction).
Fish are more effective at converting feed into body protein than cattle or chickens. It's a lot more economical, which means the fish industries can produce more food with less feed. Since less food and resources are used in the processing of food, the process is therefore less expensive.
Explanation:
- Eijiro <3
The study of fish and fish farming is important in the study of animal science in various aspects. Some of them are given below:
Fish is a rich source of protein.High economic value.Better productivity.Less expensive. What do you mean by Fish farming?Fish farming may be defined as a form of aquaculture in which fish are raised in enclosures to be sold as food.
Fish is an organism that is known as the king of aquatic habitats. Being this property the study of fish and fish farming leads to more advancement in its gene sequence, amount of protein content, and even a rough amount of its cost. On the other hand, it is also a chief source of food that contains significant protein.
Therefore, the study of fish and fish farming is important in the study of animal science in various aspects.

If the amount of atmospheric carbon dioxide were decreased, what would be the most direct effect on the ecosystem?
A. Decomposers would decrease in number
B. Some consumers would become photosynthetic
C. Producers would have less material for making food
D. Consumers and producers would increase the rate of respiration
Answer:
C. Producers would have less material for making food.
Explanation:
An ecosystem can be defined as the natural living habitats of both living and non-living organisms, in which they interact with one another. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.
A list of the types of organisms in an eco pyramid are;
I. Producers: these are autotrophs or self-feeders such as plants.
II. Primary consumers: these are herbivores that typically feed on plants such as a goat or deer.
III. Secondary consumers: these consists of carnivores that typically feed or eat flesh such as lion, tiger, cheetah, etc.
IV. Tertiary consumers: these are higher predators such as humans that aren't normally fed on by other organisms in the ecosystem.
In Biology, producers are the living organisms that are capable of manufacturing their own food and as such can provide energy or food for the other living organisms (consumers) in a food chain. Thus, producers are mainly known as the foundation of a food chain and are at the top.
A producer gets energy from the sun and converts it into food. The cells found in producers are capable of converting the energy received directly from the sun into food through a process generally referred to as photosynthesis, converting carbon dioxide from the air, water from the soil, minerals and energy from the sun into organic nutrients.
Hence, if the amount of atmospheric carbon dioxide were decreased, the most direct effect on the ecosystem is that producers would have less material for making food.
If the concentration of water inside the cell is equal to the concentration of water outside the cell, the cell is at ____________________ with its environment.

Cheests as a species of cat best known for being the fastest land animal, with the ability to sprint at speeds of up to 120
Kilometers per hour, Cheetahs have small heads, lean bodies, long legs, and a yellowish-tan coat with distinctive black spots
Cheetahs face extinction pressure from climate change, hunting by humans, and habitat destruction, which is reducing the size of
their populations, Predict how these pressures have affected the genetic diversity of cheetahs.
Answer:
Genetic diversity has decreased due to inbreeding due to dwindling population size.
Cheetahs are facing great pressures, such as climate change, destruction of their habitat, and also hunting by humans that have greatly impacted their genetic diversity.
What are the causes of inbreeding in Cheetahs?Cheetahs have experienced a very declining rate of their populations due to destruction of their habitat, and also hunting by humans that has resulted in inbreeding in their populations and loss of genetic diversity.
Due to inbreeding, cheetahs have become more exposed to genetic disorders and vulnerable to diseases, and other threats.
Climate change has also posed a great threat to the declining population of cheetahs as it has affected their habitats and food resources. Climate change causes alteration in the temperature and rainfall pattern resulting in low availability of prey and water resources. Therefore, climate change leads to the malnutrition of cheetahs and making them more susceptible to severe disease.
Therefore, cheetahs are facing extinction due to climate change, habitat destruction, and hunting by humans.

Task: Should chemical reactions be manipulated in order to meet our food and fuel needs ?
Plz explain a little bit
Explanation:
I think this is the answer
The ability to control chemical processes is increasingly being used to provide the food and fuel we require.
What are the reactions to making food?Lipid oxidations, chain reactions that lead to rancidity in foods containing oil and fat, and non-enzymatic browning reactions involving amines.
Reducing sugars are the most significant chemical process in food systems. Growing requires more than simply the bare necessities of water and sunlight.

The picture below shows the satellite image of ocean surfaces on Earth at Locations A, B, C, and D.
Which of these graphs best models the waves in the four locations?
When using images and graphs to express the results of a research, both of them should express the same information to make their interpretation easier. Option A is the one that best models the waves in the four locations.
How to express the results of a research?
There are different ways in which a researcher can correctly express the results of an experiment or research. It can be done by using images, tables, graphs, diagrams, etcetera.
Usually, combinations of one or more are used to express the same results in order to make it easier to make interpretations (for instance, tables and charts). In these cases, the same data must be expressed in all of them, so the interpretation is coherent.
In any case, there must always be a reference to what is being shown, so the persons looking at the image, chart, or table, get to know what they are looking at.
For instance, in the exposed example we can see the satellite image of ocean surfaces on Earth at different locations.
To get to understand this image by itself, we need references. These are given below in the sea surface height anomaly gradient.
This gradient explains the change in height from the lowest height -the darkest color that reflects -50 cm-, to the highest height -white expresses 50 cm-.
Letters A, B, C, and D are references to the locations that were considered.
If we want to make a graph with this same information, we need to make a good interpretation of the image and then reflect it in the graph.
In the exposed example, graph A is the one that best reflects the information provided in the image but is not entirely correct.
Image
A ⇒ red color ⇒ 30 cmB ⇒ yellow color ⇒ 10 cm C ⇒ cream/light blue ⇒ 0 cmD ⇒ light blue color ⇒ -10 cm
The graph must express the change in water surface height. This change is expressed in the Y ax of the chart.
Probably the X ax represents normal heights.
According to the information,
A and B must be over the X ax (positive values). C might be on the ax or slightly over or below it. Finally, D must be below the X ax (negative value).
Graph A is the one that best represents this information.

Answer: Homologous structures.
Explanation: The bones labeled A have similar structural arrangement in all the organisms but perform different functions in each organism
The bones labeled as A are known as homologous structures. Therefore, option D is correct.
What are homologous organs?Homologous organs are those present in several creatures that share a common ancestor and fundamental structure but differ in the roles they perform. The man's forelimbs, a cat's forelimbs, a whale's flippers, and a bat's wings are all examples of homologous organs.
Homologies are characteristics shared by two or more species and derived from their common ancestor. For instance, our common ancestor who lived more than 300 Mya ago left us with both the human five-fingered hand and the lizard's five-toed foot.
The forelimbs of penguins, bats, alligators, and humans are examples of homologous organs. Therefore, option D is correct.
