Answer:
Ratio =
Explanation:
Side of a cube, a = 20 µm
The surface area of a cube, A = 6a² (a is side of the cube)
The volume of a cube, V = a³
The ratio of the surface to volume ratio of the cell will be given by :
So, the ratio of the surface to volume ratio of the cell .
Answer:
Acetyl CoA
Explanation:
Fat, sugars and proteins are digested into their monomers namely fatty acid and glycerol, simple sugar and amino acids respectively. These simple chemicals are finally digested into acetyl CoA.
Acetyl CoA enters the TCA cycle and is completely broken down into CO2 and H2O. The energy released during redox reactions of the TCA cycle is stored in the form of NADH and FADH2 which then enter the oxidative phosphorylation.
A. direct B. indirect C. direct D. indirect
Competition occurs by direct and indirect means. Organisms interact directly by fighting (aggression) for scarce resources. Two eagles fighting over the salmon carcass and two colonies of ant clashing over a wasp are samples of aggression (direct competition)
Indirect competition happens when there is a common or limited <span>supply of at least one resource (food, water, and territory). </span>Use of this resource lessens and later depletes the amount available to others, or they compete for space.<span> Gray foxes preying on penguins and squirrels relying on nuts for food are samples of indirect competition.</span>
The answer to the question stated above is letter c. <span>Pasteur tested for microorganisms, but Redi studied larger organisms.
</span><span>
Redi experimented with rotting meat; Pasteur experimented with broth.</span> Redi disproved spontaneous generation for large organisms by illustrating that maggots arose from meat only when flies laid eggs in the meat. <span> Pasteur used his famous swan-neck flask experiment, to end the debate. On his experiment air is allowed to contact the broth. Microbes present in the dust were not able to navigate the tortuous bends in the neck of the flask. </span>
Answer:
The correct answer is letter C.
