Mine drainage is the water exiting the mine. Water and rocks that contain minerals that include sulfur react chemically to generate it.
An underwater mine is what?In order to harm or destroy surface ships or submarines, self-contained explosive devices known as naval mines are submerged in the sea. Mines are positioned and allowed to wait, unlike depth charges, until they are activated by any vessel or a specific type of vessel approaching or coming into touch with them, similar to anti-infantry vs.
What causes a mine's corrosive water to flow out?Pyrite, an iron sulfide, combines with air and water to produce sulfuric acid and dissolved iron when it is exposed, which causes mine drainage. Red, orange, or yellow sediments can occur as some or all of this iron precipitates, forming the bottom of streams carrying mine drainage.

RISC carrying siRNA differs from miRNA in having different argonaute proteins, as RISC (siRNA) can have argonaute 2 whereas the RISC (miRNA) can have argonaute 1-4.
A multiprotein complex called the RNA-induced silencing complex (RISC) contains one strand of a small interfering RNA (siRNA) or micro RNA (miRNA). The siRNA or miRNA serves as a template for RISC, which recognizes complementary mRNA. When it locates a complementary strand, RNase is triggered, and the RNA is cut.

why is fructose toxic to liver cells, but not muscle cells, in individuals with a defect in the enzyme aldolase b?
Fructose is toxic to liver cells, but not muscle cells, in individuals with a defect in the enzyme aldolase, because muscle cells employ hexokinase to convert glucose to glucose-6P, which cannot be further metabolized, liver cells cannot.
In the second stage of the metabolism of fructose, aldolase B is in charge of converting the compound fructose-1-phosphate into glyceraldehyde and dihydroxyacetone phosphate. Aldolase B is also involved in the breakdown of the simple sugar glucose, but to a lesser extent. The lack of the enzyme aldolase B is a defining feature of the autosomal recessive condition known as inherited fructose intolerance.
Fructose-1-phosphate is broken down into glyceraldehyde and dihydroxyacetone phosphate by the crucial enzyme aldolase B. Phosphate depletion and fructose 1-phosphate buildup in the liver are symptoms of aldolase B deficiency. As a result, gluconeogenesis and glycogenolysis are suppressed, which inhibits the synthesis of proteins and causes liver failure.

What is composed of cells that produce hormones and secrete them into the bloodstream?.
Endocrine glands have composed of cells that produce hormones and secrete them into the bloodstream.
Endocrine glands are also known as hormone-producing glands. These glands are scattered in various parts of the body and have their respective roles in regulating organ systems. Therefore, their health needs to be maintained in order to function normally.
Various Glands in Endocrine Glands1. Pituitary Gland
The pituitary gland is a small gland located at the base of the brain. Despite its small size, the function of this gland is very large in the endocrine system. This gland is considered the 'leader' of all endocrine glands, as it can produce various hormones that regulate the functions of other endocrine glands.
2. Thyroid Gland
The thyroid gland produces the hormones thyroxine (T4) and triiodothyronine (T3) which are responsible for regulating the body's metabolic processes. In addition, this hormone also plays a role in the formation of bone tissue, body temperature regulation, and the development of the brain and nervous system.
3. Parathyroid glands
This gland releases parathyroid hormone which plays a role in regulating calcium levels in the blood. The task of this hormone is assisted by the hormone calcitonin which is produced by the thyroid gland.
4. Adrenal glands
The adrenal glands are divided into two parts, namely the cortex and the medulla. The cortex is responsible for producing steroid hormones that regulate metabolism, the immune system, the body's response to stress, and the development and function of sexual organs.
Meanwhile, the medulla plays a role in producing the hormone epinephrine or adrenaline to increase blood pressure and heart rate.
5. Pancreatic gland
The pancreas gland produces two hormones, namely the hormone glucagon and the hormone insulin. Glucagon functions to store and increase blood sugar levels, while insulin functions to lower blood sugar levels.
6. Reproductive glands
The male reproductive glands or testes are located in the testicles or scrotum, while the female reproductive glands, the ovaries or ovaries, are located in the pelvis.
The testes produce the hormone testosterone to produce sperm, while the ovaries produce the hormones estrogen and progesterone which play a role in supporting pregnancy and regulating the process of ovulation and menstruation.

According to appearances, Green had the least amount of plant growth, while Blue had the greatest.
According to Petronus's (2016), for photosynthesis to occur, a cellular component like the pigment must be present because it gives plants their colour and traps sunlight in the process. The light spectrum, which is employed in most virtual labs for experimentation, has a tendency to have both long and short waves that contain various colours. Chlorophyll helps the photosynthesizing plant capture both blue and red light, according to Couto.

give examples of situation when a substance cannot be moved into a cell by osmosis or diffusion and how active transport solves the problem
When a substance cannot move by osmosis or diffusion, it is because it cannot cross the plasma membrane due to its charge or size, and if it is by diffusion, it is because it is against its concentration gradient.
Why can't a substance go through osmosis or diffusion?A substance could not pass through osmosis since only water can pass to the place with the highest concentration. While by diffusion it could not happen due to its size or electric charge, neither if the concentration gradient is against it.
Active transport helps in this by passing elements against their concentration gradient, generating an energy expenditure for this to occur since this movement is not energetically possible.

(create an illustrated representation of hypertonic, hypotonic and isotonic solutions using any plant or animal cell to help distinguish between the three types of environments.)
If surrounding solution has higher solute concentration compared to inside the cell, then it is called hypertonic solution. A hypertonic solution has a higher concentration of solutes. If surrounding solution has high solvent concentration compared to the inside of the cell, then it is called hypotonic solution. A hypotonic solution has a lower concentration of solutes than cytoplasm of cell. If both surrounding solution and solution inside the cell has same concentration of solvent and solute, then it is known as isotonic solution.
A solution can be both hypertonic and hypotonic depending on type of cell or substance kept in solution. If cell has more solutes than solution then it may swell and if it has less solutes than solution then it may shrink.
If animal or plant cell is kept in hypertonic solution that is solution with higher solute concentration than water molecules will move outside of the cell from inside of the cell ie; exosmosis will take place. Due to this reason, both animal as well as plant cell will shrink. Plant cell is said to become plasmolysed.
In hypotonic solution, animal and plant cell will swell as solution has lower solute concentration than inside of the cell present in solution. Animal cell will swell and ultimately burst ie cell will lysed but, plant cell will not burst it will swell and develop turgor pressure. Hence, plant cell becomes turgid in hypotonic solution.
