Answer:

FALSE

Explanation:

The process described in the question is bottom-top processing that progresses from the sense organs before moving up to the brain.

Top-down processing is one of the 2 general processes of how sensation and perception of sensory information is being processed in the mind. Top-down processing refers to the process pattern of forming perception based on your cognition, or what the brain already knows or expects. Meaning is formed based on a given context that is already known, as well as from general to specific. It involves the processing of sensory information from the brain down to other sensory organs.  

  • For example, our prior knowledge of the spelling of LOVE would make us pronounce and assume LOV3 as LOVE, when someone writes it that way. Without much thought, we quickly take LOV3 to mean LOVE.

What is the pH if 20 mL of pH = 2 solution is diluted to a final volume of 600 mL?
Mashutka [201]

Explanation:

Hydrogen atoms contain 1 proton and 1 electron while being devoid of neutrons. When they lose their electron they form an ion or H+, a particle carrying a unit of positive charge.  pH measures how basic or acidic a water-based solutions are, with a formula for pH is

pH = -log[H+].

...where pH is -base 10 log of the concentration of hydrogen ions within the solution.

Initial volume= 20 mL

Final volume= 600 mL

# of dilutions= \frac{600}{20} = 30

for a pH 2= [H+]= 10^{=2}

∴ [H+]=  \frac{10^{-2}}{30} = 3.333 * 10^{-4}

and pH is an antilog of [H+]= - log \frac{10^{-2}}{30} = 3.333 * 10^{-4}

∴pH = 3.47

A student recorded the height of each student in the school. She then made a bar graph of her results. She observed
eimsori [14]

Answer:

Height is affected by multiple pairs of genes on different chromosomes.

Explanation:  

The quantitative traits are those whose inheritance pattern is the result of the action of multiple genes that act together with the environment. The distribution of quantitative traits in the population follows a bell-shaped curve, which is referred to as normal distribution or Gaussian distribution. These traits are 'quantitative' because they vary among individuals in the population to produce a continuous range of phenotypic values. Examples of quantitative traits include, among others, metabolic rate, height, and weight.

What is allosteric regulation? a) In allosteric regulation, genes are expressed constitutively. b) In allosteric regulation, a s
andrew11 [14]

Answer:

b) In allosteric regulation, a small molecule binds to a large protein and causes it to change its shape and activity.

Explanation:

Allosteric regulation refers to the activity control of an enzyme by binding small molecules to regulatory sites on It. This binding causes an alteration of the protein conformation and consequently the shape of the active site and its catalytic activity are altered. Regulatory enzymes can act by either stimulating or inhibiting the activity of a protein.
