How can fish farming still deplete ecosystems?
A. Farmed fish often eat wild-caught fish.
B. Fish farming always occurs in the wild.
C. Farmed fish always live in self-contained units.
D.Farmed fish can be fed sustainably grown grains.
Answer:
B.
Explanation:
How does fish farming harm the local ecosystem?
Fish-farming is thought to contribute to eutrophication and the worldwide growth of this industry is of concern. Faeces and uneaten food pellets from fish farms alter the organic matter in the sediment, which can change the consumption of oxygen and cause local eutrophication.

Borh worker and queen bee are developed from fruel eggs .but why workers bee can not reproduce like that of queen bee?
Answer:
------->
Explanation: Why worker egg-laying occurs in honey bee colonies. Usually, colony behavior, egg-laying, and ovary development in worker honey bees are prevented by queen pheromones and open brood pheromones. However, in the absence of these regulating pheromones, workers may develop ovaries that will enable them to lay their own eggs.

the special type of cell division required to produce gametes is called
Answer: Meiosis
Explanation:
Meiosis creates gamete "daughter cells" that have half the chromosomes as a normal cell that would be created during mitosis, which is the division and reproduction of identical cells from the parent. In humans, a regular 46 chromosome cell divides through meiosis to create gametes with 23 chromosomes. This is important to be sure that an organism that is made through reproduction with sperm and egg has the correct number of chromosomes.
Identity the stomata components. record your answer under "" slide 2"" on your lab report
Stomata are involved in gas interchange and transpiration. The components of stomata are the pore, the guard cells, subsidiary cells, and the stomatic chamber.
What are stomata?On the leafs' surfaces, there are small pores that regulate gas interchange and transpiration. These openings are the Stomata.
Gas interchange ⇒ CO₂ gets into the plant, and O₂ leaves it Transpiration process ⇒ water expel
Stomata opening and closure depend on water and CO₂ concentration inside the plant.
These pores are surrounded by two kidney-shaped cells called Guard cells. They expand or contract according to the plants' needs, causing the stomata to open or close.
The space left between these guard cells is the pore.
Other cells that vary in shape and number are surrounding the guard cells and are functionally associated with them. These are the subsidiary cells.
The pore is connected to a wide intercellular space inside the leaves called the stomatic chamber.
According to this framework, the components of the stomata are,

What shuffles genes and increases genetic variation in gametes during meiosis, when these homologous pairs are paired up ?
Meiosis is referred to as reduction division as it divides the chromosome number in half. Crossing over or recombination is the main reason of shuffled genes and increased genetic variation in gametes in meiotic cell division as the homologous pairs are paired up during prophase.
What is crossing over?Crossing over is referred to as the exchange of genes of DNA between paired homologous chromosomes. It actually occurs during the development of egg and sperm cells i.e., during meiosis.
It is an enzyme-mediated step, in which the exchange of genetic material takes place between non-sister chromatids of homologous chromosomes.
It actually occurs at the pachytene stage of prophase I of meiosis cell division.
Thus, it can be concluded that the crossing over is the main reason of shuffled genes and increased genetic variation.

select all that apply.
a

Nitrogen is an essential component for living cells, as it is involved in synthesis of amino acids and nucleic acids. These amino acids polymerize to form proteins. So the organic macromolecules do living things build using nitrogen is protein and nucleic acids, i.e., option a and d.
What are amino acids?Amino acids are the smallest unit or one can say building block of protein.
It usually have an amino group and a carboxyl group and a side chain. It is linked together by peptide bonds.
As it has an amino group, it requires nitrogen for its formation, and it will ultimately form protein.
Nitrogen is also required for the formation of nucleic acids i.e., DNA and RNA.
Thus, the correct option is a and d.

In Cellular Respiration, Glucose is transformed into?
In Cellular Respiration, Glucose is transformed into ATP.
What is ATP?Adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose.
