Dark adaptation ________. Dark adaptation ________. primarily involves improvement of acuity and color vision involves accumulation of rhodopsin results in inhibition of rod function is much faster than light adaptation
Answer:
involves accumulation of rhodopsin
Explanation:
This is because dark adaptation is the ability of the eye to react to low light sensitivity and all the rod pigments of the eye bleached out which is as a result to the bright light and this make the rods nonfunctional in the initial state . Once you are in the dark, rhodopsin regenerates and tthis lead to increase in retina sensitive continuously.

Please select the best answer from the choices provided
Answer:
D
Explanation:
The common myth regarding hypnosis is Hypnotized people can remember the past accurately.
Who are hypnotized people?Focused attention (the selective attention/selective inattention hypothesis, SASI), decreased peripheral awareness, and an improved ability to respond to suggestion are all characteristics of hypnosis in humans.
Conflicting ideas exist to explain hypnosis and related phenomena. According to beliefs about altered states of consciousness, hypnosis is an altered mental state or trance characterized by a heightened level of awareness beyond that of ordinary consciousness.
A person is reported to have improved focus and concentration while under hypnosis, as well as a greater receptivity to suggestions.

Select all statements that correctly explain the structure and role of sugar molecules in organisms.
Answer:
where are the statements of it??
Explanation:
The two genes f and g, code for body size and aggressiveness, respectively. The F allele is dominant over f, and codes for a larger body size. The G allele is dominant over g, and codes for more aggressive ants. You perform a Mendelian dihybrid cross (NOT a test cross) on these traits. If there is no recombination between these genes (recombination frequency = 0.00), what ratio should you see phenotypes in in the offspring? (note that the parent generation was made up of large aggressive ants and small docile ants.)
A. 9 large aggressive:3 large docile:3 small aggressive: 1 small docile
B. 1 large aggressive:1large docile:1small aggressive:1small docile
C. 12 large aggressive:4 small docile (i.e. 3 large aggressive:1small docile)
D. None of the above
Answer:
The correct answer is option C.
Explanation:
As it is given that, a Mendelian cross is performed between two parents resulted by cross the parents. This suggests that the parents or P generation has zero recombination hence the genotype of Parents would be AA and aa in nature. Therefore, all the F1 generation offspring were Aa in nature. The selfing of the F1 offspring will be:
A a
A AA Aa
a Aa aa
Genotype: AA: Aa: aa :: 1:2:1
Phenotype: Dominant: recessive :: 3:1

Feedback loops are when the body responds to signals, like insulin, that appear when the balance of something is off. When blood sugar is too high, insulin signals the liver to absorb more blood sugar, returning it to normal. When blood sugar is low, glucagon signals the body to release stored glucose to raise blood sugar back to normal.
Ingestion is when food comes into the body through the mouth and down the esophagus. Digestion begins with chemically with enzymes in saliva, and mechanically with the teeth, and continues when food (as a bolus) enters the stomach to be dissolved by acid and pepsin. Food (chyme) then goes into the small intestine where nutrients are absorbed through the villi. Waste is then eliminated through the large intestine, rectum, and anus.

A coyote runs 30 meters across the field in 120 seconds. Find the SPEED
of the coyote. Include units and all digits. *
0 points
Your answer
Answer:
The correct answer is - 15 m/min.
Explanation:
Given:
Distance = 30 meter
Time = 120 second or 2 minutes
speed = ?
We know:
The speed of any moving can be calculated by the distance it traveled per unit of time,
So,
speed = Distance/time
Solution:
Speed of coyote = 30/2 meter/min
= 15 meter/min or 0.9 km/hour
Thus, the correct answer is - 15 meter/min or 0.9 km/hour
Depending on the size of the indel, both indels and substitutions are considered
a type of point mutation. However, the most fundamental key.
difference between indels and substitutions is:
1. Large indels can be several thousand base pairs in size.
2. Substitutions can result in an indel, but not vice versa
3. Indels can alter the open reading frame, but substitutions cannot
4. Substitutions change the amino acid sequence of a protein
Answer:
3. Indels can alter the open reading frame, but substitutions cannot
Explanation:
INDEL is a term used in genetics to represent a mutation caused by insertion of nucleotides or deletion of nucleotides from a sequence. As stated in this question, the insertion or deletion can be a point mutation (involving a single base) as well as substitution mutation.
Insertion mutation adds nucleotide(s) to the sequence, deletion mutation removes nucleotide(s) from the sequence and substitution mutation replaces nucleotide(s). Based on the fact that INDEL mutation will either shorten or lengthen the sequence, it can alter the open reading frame whereas substitution cannot.

Given an unusual cell with an intracellular fluid containing 10 mM calcium and an extracellular fluid containing 1 mM calcium. If the cell membrane is permeable only to calcium ions, what is the voltage across the membrane? Assume that the system is at equilibrium and at body temperature.
Answer:
The correct answer is: -31 mV
Explanation:
Given:
Intracellular fluid concentration = 10 mM
Exracellular fluid concentration = 1 mM
temperature = 237+37 = 310 k
Z = 2
F= 96500 C mol-^1
R = 8.314 J MOL-^1K-^1
Formula -
Ex = (RT/ZF) ln ([x]out/[x]in)
= [tex]\frac{8.314*310*2.303}{2*96500} log 10 \frac{1mM}{10mM}[/tex]
= -0.03075447679*1/10 log 10

Answer:
A. As mass increases, volume increases
Explanation:
The table in the image attached is depicting the relationship between the mass, volume and density of a certain metal A. Ideally, the density of a substance is directly proportional to its mass, and indirectly proportional to its volume.
However, based on the data provided on this table, the MASS (g) increased as the VOLUME (mL) increased and vice versa. The highest mass of 10.10g has a volume of 3.8mL. This value of volume decreased with decreasing mass. Hence, based on the information of the table, as mass increases, volume increases.
