<em>Protein synthesis is the process whereby biological cells generate new proteins and it is balanced by the loss of cellular proteins via degradation or export.</em>
It helps the body build muscles and protects from germs and virus.
Answers
When doing medical research with human subjects, the following are unavoidable limitations;
It’s often impossible to repeat trials on the same subjects.
Subjects may report an inaccurate medical history.
It can be difficult to control all possible variables
There are ethical or privacy concerns to consider.
Explanation
When doing a medical research that involves human subjects it should be voluntary, informed and consent. The researchers should respect the persons treated as autonomous agents. The volunteers should be protected from physical, mental and emotional harm. The benefits should outweigh the costs.
Answer:
The scientific study of life, called <u>Biology</u><u>, </u>can be organized around several themes. As the biological hierachy builds from molecules on up to ecosystems, each level has <u> emergent properties</u> that result from interactions among component parts. Life's basic unit of <u>structure and function</u> is the cell, which occurs in two basic forms- prokaryotic and eukaryotic . As organisms interact with the environment, <u>nutrients and chemicals</u><u> </u>cycle within an ecosystem, while energy flows one way from sunlight -> chemical energy -> heat. According to the core theme of <u>evolution </u>all of life is related by common descent. Life was diversified as <u>natural selection</u> had led to the gradual accumulation of adaptations that fit populations to the environment.
Explanation:
Emergent properties- Properties that is exhibited by a group of individuals as a result of interaction among them.
Evolution- the process by which populations develop new characteristic and become more efficient than their ancestors.
Natural selection- A phenomena in which only fittest organisms of a population are allowed to survive in a given environment. This play a key role in evolution.
Answer:
to maintain homeostasis these things must be controlled:
- pH levels in the body (I.e. the stomach)
- wanted levels
- sugar levels
- level of Co2 in our bodies
- blood glucose levels
- body temperature
we maintain homeostasis to ensure that our enzymes, which speed up or make chemical reactions are working well and work within he required conditions.
external things we can do to maintain homeostasis:
- wearing the appropriate clothing in summer and winter
- consuming the correct temperature beverages (i.e. cold drinks in summer)
- consumitn the correct temperature and nutrient required foods (I.e. nutritious pumpkin soup in winter)
we also shiver when we are cold - the friction between our muscles produces heat.
