<span>Basically both operate by bouncing tiny particles or waves off of objects in order to make them visible. Electrons are smaller than light photons so we can see smaller objects clearly with electron microscopes. There are disadvantages though. First, color is a function of light wave frequency so we can't see electron micrographs in color. Color can be added artificially though by computer to differentiate structures, (think photoshop). Also, we cannot see electrons so we make them visible by bouncing them off a cathode ray screen similar to a TV set or computer monitor</span>

cells can be observed in plants, animals, fungi, protists, bacteria, and archaea. which part of the cell theory?
valentina_108 [34]

Answer:

This statement corresponds to the first postulate of the cell theory:

All living things, whether they be unicellular or multicellular, are made up of cells.

Explanation:

The statement indicates the presence of universality in the composition of all living things by stating that cells can be observed in all organisms in the 6 kingdoms of life.

Cell Theory:

Cell Theory is the fundamental principle of biology. It states that:

  1. All living things are made up of cells, whether they be unicellular or multicellular.
  2. All cells are produced from pre-existing cells,not from spontaneous generation.
  3. The cell is the basic functional and structural unit of life.

Suppose that 1 mL of an enzyme solution can completely catalyze 10 mL of substrate in 8 minutes. Now suppose that you change the
VLD [36.1K]

Answer:

1. b. The reaction rate will remain steady over the entire 8 minutes.

2. c. The reaction rate approach zero before 8 minutes.

3. a. The reaction rate will be close to zero over the entire 8 minutes.

4. b. The reaction rate will remain steady over the entire 8 minutes.

Explanation:

When 0.5 mL of enzyme is introduced with water, the reaction will remain steady. When more substrate solution is mixed with water, then reaction will approach to zero depending on the amount of substrate mixed with water.

What are beneficial traits?
AURORKA [14]
 <span>Beneficial traits are inherited traits (they may be phyical, biochemical, or behavioral) which increase an organism's fitness. Fitness is the technical term in biology for an organism's ability to reproduce itself, compared to other organisms. A beneficial trait, then, may either (1) increase the number of times which an organism reproduces, (2) increase the number of offspring which an organism has per reproductive act, or (3) increase the fitness of individual offspring. These three are not, of course, mutually exclusive. </span>

Question text Hyperpolarization means that the ________.
Fed [463]

Hyperpolarization is a change in a cell's membrane potential that makes it more negative. It is the opposite of a depolarization. It inhibits action potentials by increasing the stimulus required to move the membrane potential to the action potential threshold.
