The five main characteristics are foot region, hard exoskeleton, bilateral symmetry, left and right limbs and a segmented body.
Answer:
D) They can increase the reaction rate for a given reaction by a thousand-fold or more.
Explanation:
Enzymes are like catalysts with the only difference that they are bio-molecules. Biochemical/chemical reactions are slow because of 'transition state barriers' which require a lot of energy to overcome so enzymes rather than overcoming transition state barrier provide an alternate pathway for biochemical reactions which require comparatively less energy. Thus presence of an enzyme leads to an increase in reaction rate because alternate pathway which requires less energy makes the rate of chemical reaction rapid by a thousand-fold or more.
I think it C hope this helps
Answer:
Kidneys
Explanation:
The kidneys remove wastes and excess water in the body through the urine, as urine flows from the kidneys to the bladder through two thin tubes located on both sides of the bladder called the ureter, and the bladder stores urine, and each of the kidneys consists of about one million filtering units called the renal tubular unit contains Each renal tubular unit has a filter called the glomerulus and tubule, and the renal tubular unit operates through a two-step process:
glomerulus: filters blood.
Tubule: Returns the necessary substances to the blood and removes waste.
False because extrusive rocks have fine-grained texture due to the rapid cooling of magna above the earth surface. On the other hand extrusive rocks have course grained texture due to slow cooling of magna beneath the Earth's surface
