Answer:
· As particles get smaller, their magnetic properties, particularly with regard to temperature, also diminish. However, several strains of bacteria produce magnetite – fine, uniform nanoparticles that have desirable magnetic properties. These magneto tactic bacteria use a protein to form crystalline particles about 50 nanometers in size.
Answer:
False. DNA replication in prokaryotes occurs in the cytoplasm, for example
Answer:
Explained
Explanation:
No, Homeostatic regulation requires Three components namely, a receptor, a control center and an effector. Without a receptor, there cannot be homeostatic regulation. Even though it seems that heart rate varies and returns to some number, this is not technically homeostatic regulation. Blood pressure is homeostatically regulated - it has baroreceptors that monitor pressure, the brainstem that receives the information and nerves that then activate blood vessels to constrict or dilate to correct pressure (as well as other effectors) - but heart rate is not. Heart rate is not monitored by any neuron. Absolute water content of the body is not homeostatically regulated either - no neuron detects the number of water molecules, although neurons do detect the relative saltiness of the body.
<span>The Earth rotates once in about 24 hours with respect to the sun and once every 23 hours,
56 minutes and 4 seconds with respect to the stars. Earth's
rotation is slowing slightly with time; thus, a day was shorter in the
past.</span>
