Answer:
There is growing evidence to indicate that age-related declines in growth hormone (GH), insulin-like growth factor (IGF)-1, and androgen and estrogen production play a role in the pathogenesis of sarcopenia (an age-related decline in muscle mass and quality). Although GH supplementation has been reported to increase lean body mass in elderly individuals, the high incidence of adverse effects combined with a very high cost has limited the applicability of this form of therapy. The assessment of an alternative approach to enhance the GH/IGF-1 axis in the elderly by using GH-releasing hormone and other secretagogues is currently under way and is showing some promise. Testosterone replacement therapy may increase muscle mass and strength and decrease body fat in hypogonadal elderly men. Long-term randomised, controlled trials are needed, however, to better define the risk-benefit ratio of this form of therapy before it can be recommended. Available data are currently insufficient to decide what role estrogen replacement therapy may play in the management of sarcopenia. Therefore, although the evidence linking age-related hormonal changes to the development of sarcopenia is rapidly growing, it is still too early to determine the clinical utility of hormonal supplementation in the management of sarcopenia.

What is a "fatberg"? What causes it to form? How is it
eliminated?
Answer:
a very large mass of solid waste in a sewerage system, consisting especially of congealed fat and personal hygiene products that have been flushed down toilets.
They are caused by oil, grease and fat being poured down sinks, where they congeal and stick to sewer walls. Once this build-up has occurred, other waste that enters the sewer can often stick to the fat
The broken up fatberg pieces are then removed from the pipe by manual excavation, powerful vacuumation tanker units
Explanation:
Answer:
a fatberg is a rock like mass of waste matter in the sewer system formed by the combination of flush non-degradable solids such as wet wipes and congealed grease or cooking fat. fat birds have formed and sewers worldwide with the rise and usage of disposable cloth. to eliminate fatburgs you have to first break them up into smaller chunks to do this we use special water jets with process 10 gallon per minute at a pressure of 3,000psi.a broken up fatberg pieces are then removed from the pipe by manual extraction powerful vacuumation tanker units or combination of both.

Is M. Tuberculosis a Eubacteria or Archaebacteria?
Answer:
MYCOBACTERIA. Mycobacteria are classified as Gram-positive bacteria, but they have features of both Gram-positive and Gram-negative organisms. Pathogenic mycobacteria include the organisms that cause tuberculosis and leprosy and are intracellular parasites, replicating within modified phagosomes of macrophages.
Explanation:
Answer:
As the spores germinate, they produce neurotoxins which, if ingested, leads to paralysis and either respiratory or cardiac failure. A very important disease-causing bacterium in the Western Cape is Mycobacterium tuberculosis, the bacterium that causes TB.

A. The products of cellular respiration are the products of photosynthesis
B. The reactants of photosynthesis are the reactants of cellular respiration
C. The reactants and products of photosynthesis has no relationship with the reactants and products of cellular respiration
D. The products of cellular respiration are the reactants of photosynthesis
Answer:
B is the answer
Explanation:
The correct response regarding the relationship between photosynthesis and cellular respiration is The reactants of photosynthesis are the reactants of cellular respiration. The correct option is B.
What is photosynthesis?
Photosynthesis is a process of transforming solar energy into chemical energy, which is then stored for later use. The majority of the time, this mechanism powers the planet's life systems.
The process by which sugar is broken down in the presence of oxygen in the cell to release energy in the form of ATP is known as cellular respiration. Water and carbon dioxide are waste products of this process.
So, photosynthesis is a process of anabolism process of food which produces energy, and for cellular respiration, glucose is combined with oxygen to form energy.
Thus, the correct option is B.

a) luster
b) cleavage
c) hardness
can someone plss help me??
Answer:
Luster
Explanation:
luster is the only answer that has to do with light. Luster is measured by the way a mineral reflects light.
Cleavage has to do with breaking minerals apart along certain fracture lines. Cleavage is not the answer.
Hardness is a test where one mineral is used to scratch another. The one that does the scratching is harder than the one that is scratched.

How does the carbon cycle support the Law of Conservation of Mass?
The carbon cycle supports the Law of Conservation of Mass, as the law states, the carbon also reuse and reabsorb in the carbon cycle.
What is the carbon cycle?
The carbon cycle is the movement of carbon from the atmosphere to plants and organisms. Carbon is coal when burned turn into gas.
The majority of carbon is kept in rocks and sediments; the remainder is kept in the ocean, atmosphere, and living things.
According to the Law of Conservation of Matter, matter can be created or destruct. Because the carbon cycle recycles the same carbon atoms, it serves as an illustration of the Law. Some carbon is stored for future growth, and some are used for energy.
Thus, because carbon is reused and reabsorbed in the carbon cycle, the Law of Conservation of Mass is supported by this law.
