Role of hormones in bullet points
Please help!
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.

A population of sea urchins in a kelp forest ecosystem is being over-fished. A team of students believe that a decline in the number of sea urchins will affect the organisms in the kelp forest ecosystem. The kelp forest food web below shows the relationships among the organisms in the kelp forest ecosystem.
Answer:
Explanation:
This response shows some understanding of the question. The ecological relationships among the otter, crab, and urchin are addressed in a very general manner (kelp crabs and sea urchins feed off of kelp, only to be eaten by the sea otter). In a further explanation, the student overstates the effect of a decrease in the populations of the organisms. (The sea urchin and crab won't get the food from the kelp and die off. The otter will starve and die off too.) The supporting details are minimally effective.

What is the solute potential (ΨS ) of a 3.0 M NaCL solution at 27°C under standard atmospheric conditions?
Answer:
149.58 bars
Explanation:
The solute potential (ΨS) of a solution is given by:
ΨS = iCRT
Where i = ionization constant of the solution, C = molar concentration of the solution, R = pressure constant =0.0831 liter bars/mole-K, and T = temperature in Kelvin.
NaCl dissociates in water to give Na and Cl ions, hence, i = 2
T = 27 + 273 = 300 Kelvin
C = 3.0 M
ΨS = 2 x 3 x 0.0831 x 300
= 149.58 bars.

Transcription is the process that must happen in order to make
Answer:
a protein
Explanation:
Transcription is one of the three main, necessary events needed for proteins to form in a cell. This happens when DNA is transcribed to mRNA. Thymine (T) is subbed in by Uracil (U), so when transcribing, A's turn into U's, not T's.

-Dr. Walter Snelling discovered in 1911
-it is a gas becomes a liquid under moderate pressure or when cold
-it is a portable energy source used in Barbecue grills in hot air balloons
what is it?
The gas that Dr. Walter Snelling discovered in 1911 that becomes a liquid under moderate pressure and acts as an energy source is propane.
Properties of PropanePropane is a gas at room temperature and it was isolated by Dr. Walter Snelling around 1911 in the process of trying to stabilize gasoline.
At cold temperatures or moderate pressure, propane becomes a liquid.
Propane has been and is still being used as an energy source in cooking, powering vehicles, and cutting metals in industrial welding.

Why do cells spend the least time in telophase?
Answer:
Anaphase is the shortest phase of mitosis. In anaphase, the sister chromatids are pulled apart to opposite ends of the cell. In metaphase, chromosomes line up along the metaphase plate.Metaphase takes a short amount of time to complete. Telophase is the next to the shortest phase of mitosis after anaphase.

The viruses use the cell's genetic material to replicate its viral genome.
The viruses use the cell's organelles to replicate its host's genome.
The viruses use the cell's genetic material to replicate its host's genome.
Answer:
The virus uses the cell's genetic material to replicate its viral genome
Explanation:
During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material within hence further during the uncoating and replication, and assembly, the viral DNA or RNA incorporates itself into the host cell's genetic material and induces it to replicate the viral genome.
