Apparent death, colloquially known as playing dead, feigning death, or playing possum, is a behavior in which animals take on the appearance of being dead. This form of animal deception is an adaptive behavior also known as tonic immobility or thanatosis. Apparent death can be used as a defense mechanism or as a form of aggressive mimicry, and occurs in a wide range of animals.

When induced by humans, the state is sometimes colloquially known as animal hypnosis. According to Gilman et al.,[1] the investigation of "animal hypnosis" dates back to the year 1646 in a report by Athanasius Kircher.

Which of the following best represents the relationship of the concentration of hydrogen ions between water, vinegar, and ammoni

aalyn [17]

Answer: The second image best represents the relationship of the concentration of hydrogen ions between water, vinegar and ammonia.

Explanation: pH is the measure of alkalinity and acidity of a substance in a logarithmic scale.

Mathematically,

$pH=-\log[H^+]$

The solutions which lie in the pH range of 0 - 6.9 are considered as acidic solutions and they have more hydrogen ion concentration.

The solution which has a pH value of 7 is considered as a neutral solution and this solution has same hydrogen and hydroxide ion concentration.

The solutions which lie in the pH range of 7.1 - 14 are considered as basic solutions and they have less hydrogen ion concentration.

For vinegar, the hydrogen ion concentration is very high.

For water, the hydrogen ion concentration will be equal to the hydroxide ion concentration.

For ammonia, the hydrogen ion concentration is very less.

Scientists have successfully cloned animals, including mammals such as sheep. Which statement provides the most likely reason th

tigry1 [53]

Answer:

4) Some people consider human genetic experiments

unethical.

Explanation:

1) Humans have DNA that is structurally very different from

other mammals.

2) Cloning can only he performed on animals that normally

reproduce asexually.

3) Human genes are made of too many different types of

simple sugars.

4) Some people consider human genetic experiments

unethical.

The statement that provides the most likely reason that a human has not yet been cloned is that some people consider human genetic experiment unethical.

Option 1 is incorrect because human DNA is similar in structure to other living organisms with components such as a phosphate group, a deoxyribose sugar and purine/pyrimidine bases.

Option 2 is incorrect because cloning is not limited to asexually reproducing organisms only. Sheep, for example, produces only sexually and has been successfully been cloned.

Option 3 is incorrect because human genes, just like every other organisms is consist of DNA with deoxyribose pentose sugar being one of the components. The situation of too many different types of simple sugars doe not arise.

The correct option is 4.
