The correct answer is D. Just noticeable difference.
Explanation
In psychophysics, a barely noticeable difference, usually abbreviated with lowercase letters JND, is the smallest detectable difference between an initial and a secondary level of a particular sensory stimulus.

red-green color blindness is an x-linked recessive disorder. if the mother is RGCB and the father has normal vision, what are the changes for daughters and sons to hae the trait
Answers
Answer:
The correct answer would be -
RGCB daughter - 0%
RGCB sons - 100%
Explanation:
Red-green color blindness is a sex-linked recessive disease that means it will only express in absence of the normal allele that is present on X-chromosomes. As it is known that males have only one X-chromosomes therefore, the chances are more in males to be affected in presence of the recessive gene. In this given case women s RGCB and man has normal vision. The genotype of women would be both recessive alleles XcXc and genotype of man would be XY.
The gametes would be - Xc, Xc and X, Y
then the cross:
Xc Xc
X XXc XXc
Y XcY XcY
so the offspring would be -
Carrier female = XXc (50% chance in total and 100% in daughters)
RGCB daughters = 0%
RGCB male = XcY (100% in sons and 50% of total children)

how is spark formed, and why might a spark start an explosion?
Answers
Answer:When the applied electric field exceeds the dielectric breakdown strength of the intervening medium, a spark is generated. In a mechanism known as dielectric breakdown, the exponentially increasing electrons and ions allow regions of the air in the gap to become electrically conductive.
An electrostatic spark causes the blast. The sudden rise in temperature that occurs as the mixture ignites causes a massive increase in gas pressure. The ensuing increase in pressure could collapse the chamber with a noisy explosion if the burning vapour were to be trapped.

The function of some cyclin-dependent protein kinases (CDKs) has been remarkably conserved in evolution. Indeed, coding sequence for the human protein Cdc2 is able to substitute for the CDC28 gene in S. cerevisae and allow the yeast cell to grow and mate essentially normally. The following sequence near the NH2-end of the molecule is identical in both proteins: Gly-Glu-Gly-Thr-Tyr-Gly-Val-Val-Tyr-Lys-Ala. Does this mean that nucleotide sequences of the two genes coding for this region of the polypeptide are also identical
Answers
Answer:
No, because the genetic code is redundant
Explanation:
During the translation, a single amino acid may be coded for by more than one codon. It is for that reason that the genetic code is considered to be redundant. Tryptophan is the unique amino acid specified by a single codon. In this case, it is likely that silent mutations at the nucleotide sequence that encode for the Glu-Gly-Thr-Tyr-Gly-Val-Val-Tyr-Lys-Ala protein motif might have accumulated during the evolution of both CDK genes, modifying thus their nucleotide sequences while preserving the same protein sequence.

Che healthy way to lose weight is to...
Drink a lot of water
O Take in slightly less calories than you use daily
O Eat no fats
O Eat no carbohydrates
1 point
Answers
Answer:
O Take in slightly less calories than you use daily
Explanation:
It has been shown that the healthiest diets to lose weight are those where individuals consume fewer calories than normal and simultaneously by taking care of consuming all essential nutrients in adequate quantities.
The essential nutrients to be consumed in a healthy diet include:
1- macronutrients, especially proteins (amino acids) to avoid muscle loss as well as normal metabolic functions, and fats, which are required to absorb some micronutrients (i.e., liposoluble vitamins)
2- micronutrients, which include vitamins (e.g., vitamin D, vitamin C, etc) and minerals (e.g., iron, calcium, etc).
Sleep is an important need for people, explain sleep and four
different stages of sleep.
Answers
Answer:
Stage 1 non-REM sleep is the changeover from wakefulness to sleep. ...
Stage 2 non-REM sleep is a period of light sleep before you enter deeper sleep. ...
Stage 3 non-REM sleep is the period of deep sleep that you need to feel refreshed in the morning. ...
REM sleep first occurs about 90 minutes after falling asleep.
Explanation:
Sleep is an important part of your daily routine—you spend about one-third of your time doing it. Quality sleep – and getting enough of it at the right times -- is as essential to survival as food and water. Without sleep you can’t form or maintain the pathways in your brain that let you learn and create new memories, and it’s harder to concentrate and respond quickly.
Stages of sleepstage 1 non-REM sleep is the changeover from wakefulness to sleep. During this short period (lasting several minutes) of relatively light sleep, your heartbeat, breathing, and eye movements slow, and your muscles relax with occasional twitches. Your brain waves begin to slow from their daytime wakefulness patterns.
Stage 2 non-REM sleep is a period of light sleep before you enter deeper sleep. Your heartbeat and breathing slow, and muscles relax even further. Your body temperature drops and eye movements stop. Brain wave activity slows but is marked by brief bursts of electrical activity. You spend more of your repeated sleep cycles in stage 2 sleep than in other sleep stages.
Stage 3 non-REM sleep is the period of deep sleep that you need to feel refreshed in the morning. It occurs in longer periods during the first half of the night. Your heartbeat and breathing slow to their lowest levels during sleep. Your muscles are relaxed and it may be difficult to awaken you. Brain waves become even slower.
REM sleep first occurs about 90 minutes after falling asleep. Your eyes move rapidly from side to side behind closed eyelids. Mixed frequency brain wave activity becomes closer to that seen in wakefulness. Your breathing becomes faster and irregular, and your heart rate and blood pressure increase to near waking levels. Most of your dreaming occurs during REM sleep, although some can also occur in non-REM sleep. Your arm and leg muscles become temporarily paralyzed, which prevents you from acting out your dreams. As you age, you sleep less of your time in REM sleep. Memory consolidation most likely requires both non-REM and REM sleep.
One species called the naked mole-rat, has some unique differences. They have a social structure similar to that of ants and bees, they are smaller in size and are mostly ectothermic.

Why you think this species evolved back to an ectothermic life style rather than staying endothermic like all other mammals
Answers
Answer:
May be of the environment they live or genetics.
Explanation:
This naked mole rat species evolved back to an ectothermic life style rather than staying endothermic like all other mammals because of the environment they live or change in the genetic makeup. The main reason for this evolution may be the environmental they lives or through the change in genetic makeup of this naked mole rat species so both factors can contribute in the evolution.
