how mutation occurs on replicated DNA molecules
Answer:
When strand slippage occurs during DNA replication, a DNA strand may loop out, resulting in the addition or deletion of a nucleotide on the newly-synthesized strand. ... But if this does not occur, a nucleotide that is added to the newly synthesized strand can become a permanent mutation.
Answer:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.

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.

Why do you think matter changes its form based on temperature? In science explain
Answer:
Look down to the explanation
Explanation:
Because matter is extrinsic property ( meaning it could be changed based on the enviornment), things like pressure and temperature can affect the state and form of matter. "When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation)." So if the temperature is increased, it is the cause of thermal/heat energy, and this is what makes solids into liquids, liquids to gasses, and gasses to plasma (including other additional states.

The maximum air temperature permitted for delivery vehicles when receiving shell eggs Shell eggs Receive at an air temperature of 45°F (7°C) or lower.
In which case one can reject the delivery?When receiving raw shell eggs you must reject the delivery if they don't conform to the standard range of conditions. Raw egg shells at temperature of 45°F or below should be rejected during delivery as a result of the possibility of the presence of pathogens on them which exposes individuals to diseases.
The common pathogen found in eggs is Salmonella which causes typhoid. All egg shells should be treated at higher temperatures in order to destroy them.
Raw egg shells at temperature of 45°F or below should be rejected during delivery as a result of the possibility of the presence of pathogens on them which exposes individuals to diseases.

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.
