D) Gases such as carbon dioxide and methane
And the more of these from gas emissions, etc. then the more global warming.
FYI: ozone helps to blocks cosmic gamma rays from reaching earth
Answer:
The correct answer is "C".
Homeostasis is the maintaining of stable internal conditions in the body of a living being, such as body temperature or heart rate.
The endocrine system is an organ in the body which is in charge of secreting hormones that regulate numerous functions in the body, including metabolism, growth, sexual function, sleep, and mood among others. It is an essential organ which contributes to the state of homeostasis in the body.
Explanation:
The sympathetic nervous system is a part of the autonomic nervous system that carries stress responses or "flight or flight" responses that involves feelings of rush. The activation of sympathetic nervous system therefore increases the heart rate. The parasympathetic nervous system is another part of the autonomic nervous system which is responsible for "rest and digest" responses that involves feelings of relaxation. The activation of the parasympathetic nervous system decreases the heart rate.
A continuing-care retirement community
A continuing
care retirement community is a community that provides multiple care levels all
on one campus. These multiple care levels which could include independent
living, assisted living, memory care or skilled nursing and rehabilitation are set
up to provide all of the care that one will need throughout his lifetime. For the question given above, a
continuing-care retirement community might be best alternative for this couple because
it has the resources and staff available to meet their needs and they can rest
easy if their health changes in the future.
Answer:D.D.) Suspend the cells in liquid agar culture and monitor which culture continues to grow.
Explanation
Options A-C are correct except D.
→Increase in Telomere length is indicative of abnormal growth, cancer cells can reactive telomerase to increase cell's length.
→Once a monolayer is reached; this a stage of a complete normal cell division , a cell that goes beyond this stage must be mutated. assuming all other factors are constant .
Uncontrolled cell division is an indication of virulent growth in mutated cells.
<u>Cancer cell requires a ,medium of living host to thrive, alga medium will not support growth for carcinoma cells -the correct answer. </u>
<u></u>
Completed Que.
:Imagine that you are a graduate student working in a cancer lab. You accidentally mix unlabeled tubes of carcinoma cells with tubes of normal epithelial cells. Which of the following is NOT a possible strategy to allow you to distinguish which tubes contain carcinoma cells?
A.)Monitor telomere length over time during multiple cell divisions.
B.) Plate the cells in culture and look for the culture that stops dividing once a monolayer is reached.
C.) Monitor the rate of cell division.
D.) Suspend the cells in liquid agar culture and monitor which culture continues to grow.
