Free_Kalibri [48]

Answer:

Encoding is the set of processes used to decode, store, and retrieve information

Explanation:

The processing of memory in the human brain is performed in three steps: encoding the information, storing the information and retrieving the information.

Encoding refers to the process which puts the information into the memory system of the brain. The encoding can be done effortlessly without conscious awareness or it can be done with efforts with conscious awareness.

The memory is the process which decodes, stores and retrieves the information. Thus, the selected option is correct.

A sample of unknown concentration is diluted by placing 0.2 mL into 9.8 mL of buffer and then 3 mL is placed into a standard 1x1

Lina20 [59]

Answer:

The answer is " $4.875 \ \frac{mol}{l}\\$ ".

Explanation:

The molar absorptivity value is= 12.3 $\frac {L}{mol \times cm}$

path length of cell = 1 $\ cm$

Absorbance = 1.2

Using the beer's lambert law:

$A = \varepsilon \ cl\ \ \ \ \ \ \ _{where} \\\\c= \frac{A}{ \varepsilon l } \\\\$

$= \frac{1.2}{12.3 \times 1}\\\\= 0.0975 \ \frac{mol}{L}\\$

Claculating the concentration of the solution after dilution: $(m_2)= 0.0975 \ \ \frac{mol}{L}$

find out the dilution value before concentration :

The volume taken by the dilution: $(V_1) = 0.2\ ml$

The final volume after dilution:

$(V_2) = 9.8+0.2\\$

$= 10 \ ml$

Formula:

$\bold{M_1 \times V_1 = M_2 \times V_2} \\\\ M_1= \frac{M_2 \times V_2 }{V_1}\\\\$

$= \frac{ 0.0975 \times 10 }{0.2}\\\\= \frac{ 0.975 }{0.2}\\\\ = 4.875 \ \frac{mol}{l}\\$

Korolek [52]

Evolutionary Theory of Aging describes t<span>he view that natural selection has not eliminated many harmful conditions and nonadaptive characteristics in older adults. N</span>atural selection is linked to reproductive fitness, which is present only in the earlier part of adulthood. According to evolutionary theory, possibly if some disease occurred earlier in development, it might have been eliminated many centuries ago.

Complementary pair of guanine

Scorpion4ik [409]

Answer:

Complementary base pairing is the phenomenon where in DNA guanine always hydrogen bonds to cytosine and adenine always binds to thymine. The bond between guanine and cytosine shares three hydrogen bonds compared to the A-T bond which always shares two hydrogen bonds.

Which organisms produce about half of the ox gen on Earth?

padilas [110]

B. Plants

Explanation:

Plants are the main producers of the world's total oxygen output into the atmosphere.

Oxygen is a by product of photosynthesis in plant.

During photosynthesis, green plants manufacture their food using carbon dioxide and water in the presence of sunlight.
They produce glucose in the process.
The by product of this process is oxygen gas.
Oxygen gas is released into the atmosphere by this process.
