Answer:
D
Explanation:
Humans are considered to have intrinsic dignity that can't be violated and is even protected by laws of human rights. Therefore, even when conducting experiments that will involve human subjected, it is expected by ethical standards of research are considered before being implemented. For example it is important that the experiment does not subject humans to any form of embarrassment, bodily harm, and psychological harm.
Al of these will be the consequences except C, increase in polar ice. The rise in temperature is already causing the polar ice to melt down. The further increase in temperature will make the situation of the polar ice worse. the rise in vegetation in Tundra and Tyga regions could be seen because they are very cold areas and temperature increase may help vegetations to survive.
The given question is incomplete. The complete question is:
In humans, the maintenance of a stable internal temperature is a direct result of___________.
a. detection of and reaction to stimuli in the environment
b. digestion of starches and absorption of protein from the internal environment
c. diffusion of water and excretion of glucose to the external environment
d. transport of ATP and locomotion through the environment
Answer:
a. detection of and reaction to stimuli in the environment
Explanation:
Thermoreceptors present in skin layers of the human body sense the deviation of the body temperature from the normal range. As the body temperature rises above normal, the thermoreceptors send signals to the brain which n turn signals dermal blood vessels to dilate and sweat glands to secrete sweat. The heat from the body surface is lost to the surroundings to drop the body temperature towards the normal range.
On the other hand, when the body temperature goes below the normal range, thermoreceptors send signals to the brain which in turn signals dermal blood vessels to constrict to conserve the body heat. If body temperature continues to drop, muscles are signaled to contract involuntarily to generate body heat to raise the body temperature towards the normal range.
Answer:
The correct answer from the options is Growth.
Explanation:
There are seven basic characteristics of life which separate living things from non- living things.
Growth is one of the characteristics which separate a living thing from a non- living thing. The plants use essential macromolecules for growing. The fire will not have macromolecules to grow. Hence, growth is the option that is correct.
Other options like defined boundary are incorrect because both plants and animals have a defined boundary.
Answer:
Restate your hypothesis and then state clearly and concisely whether or not your hypothesis has been supported by the experiment.
