Cultural eutrophication happens when humans greatly accelerate the input of plant nutrients to a lake.
Human activities can significantly speed up the inflow of plant nutrients into a lake when it’s close to an urban or agricultural region, a process referred to as cultural eutrophication.
What about eutrophication?The natural action of eutrophication is brought on by the buildup of nutrients in lakes and other bodies of water. Nutrient-feeding algae develop to become ugly on the water's surface, reducing its value for enjoyment and blocking water intake pipes. The process of eutrophication, which happens when the environment becomes enriched with nutrients, increases the number of plant and algae development in estuaries and coastal waters, is what causes harmful algal blooms, dead zones, and fish kills. Since eutrophication frequently results in the degradation of water quality and the reduction of dissolved oxygen in water bodies, it’s seen as a severe environmental concern. Eutrophic waters have the potential to eventually become"dead zones" that cannot sustain life. Cultural eutrophication has been linked to hypoxia, blue-green algal blooms, polluted beverage sources, and a decline in recreational options. A process referred to as eutrophication is brought on by an excess of nutrients, primarily nitrogen and phosphorus, in water. Algae thrive, spread, and color the water green as a result of feeding on the nutrients. Eutrophication are often reduced by controlling the nutrient sources, curtailing fertilizer use, using good soil management techniques, putting mathematical models to use, adopting phytoremediation, etc. Among these, raising general knowledge of eutrophication can help prevent it from happening to water bodies.Learn more about eutrophication here:

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.

(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.

CE
In the process of cellular respiration big food molecules such as glucose and sucrose are fragmented into tiny molecules with the release of energy. The process of cellular respiration is important for yeast survival like all other organisms.
Why?
This occur because small particles are rapidly fragmented whereas big molecule like sucrose takes more time. This makes large molecules less organised source of energy for yeast relatively those of smaller molecules.
Yeast can use distinct sugar and non-sugar based molecules as source of energy as follows;
Glucose
Lactose
Sucrose
Glucose is a simplest sugar molecule and yeast do not make much effort for its breakdown.
