Answer:
Organisms need carbon for building cells and energy to fuel the process; eukaryotes, in general, all follow the same basic metabolic pathways whereas prokaryotes use a variety of materials and pathways—some employed by no other organisms.
Explanation:
Answer:
Glycolysis produces pyruvate, ATP, and NADPH by oxidizing glucose. During cellular respiration, glucose combines with oxygen to form carbon dioxide, water, and ATP.
Explanation:
Answer and explanation:
One of the unordered forms of the dying cell is necrosis.
Necrosis is caused by lesions that impede internal balance control: water and some ions, especially sodium and calcium, normally pumped out, flow freely into the swelling and rupturing cell. The necrosis rupture releases into the surrounding tissue cellular content, rich in proteases, enzymes that "cut" other proteins, and other toxic substances. In addition to direct toxicity to neighboring cells, the stroke generates substances that attract immune cells, causing an intense inflammatory reaction: some types of white blood cells, especially neutrophils and macrophages, converge to necrosis tissue and ingest dead cells. Inflammation, typical of necrosis, is important for limiting infections and removing cell debris, but white blood cell activity and secretions can also damage neighboring, sometimes devastating, normal tissues.
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.
