Janet learned in science class that the amount of salt that can dissolve in a certain amount of water depends on the temperature

of the water. She decides to do an experiment to test this. She carefully adds salt, 100 mg at a time, to a cup of water and stirs until all the salt dissolves. When she has added so much salt that it will not dissolve after 5 minutes, she measures the temperature of the water. She records the temperature and the final amount of salt. She does this with cold water, cool water, room-temperature water, warm water, and hot water.
What is the independent variable in this experiment?

A. the temperature of the water
B. the amount of salt
C. the amount of water
D. how long it took the salt to dissolve

Infant nathan is smiling and "talking" with short, loud noises. his mother responds each time nathan expresses himself by smilin
Ilia_Sergeevich [38]

Infant Nathan is smiling and "talking" with short, loud noises. His mother responds each time Nathan expresses himself by smiling and talking. This interaction is described as: <u> verbal “dialogues</u><u>”</u>.

Infants' early vocalisations (language), such as crying, cooing, and babbling, serve as the foundation upon which more sophisticated structures can be build. These high-pitched voice tones with a lot of modulation are preferred by newborns.

When speaking to a young infant, parents from diverse cultures and languages naturally utilise loud noises. In the first month, cooing noises are the first "answers" that babies make. Sometime within the first month, one of these pleasant social interactions results in these subtle vocalisations.

By the second month, the majority of babies will converse verbally with their parents back and forth in a "<u>dialogues</u>" that is cooperatively controlled by both parties.

A mutation causes a dog to be born with a tail that is shorter than normal. Which best describes this mutation? It is harmful be
Vanyuwa [196]

Answer:

The correct answer is "It is neutral because it does not obviously affect the dog’s survival."

Explanation:

Even though the tail was necessary in wildness to keep the balance specially when hunting, in the domestic life it doesn't affect the dog's survival because they no longer have to fight for food, in wildness it could affect his breeding possibilities or even the possibility to be eaten, but now it doesn't.

Explain why homeostasis is important for survival? Be detailed in providing your answer to this question.
stepladder [879]

Answer:

Homeostasis is important because it's an organisms known environment. Even if you were to alter the environment by a little, it would effect the organism greatly. For example, if a rainforest's temperature changed to be similar to that of a desert's, then the inhabitants of the rainforest would die due to them being unaware of how to survive and blend in the desert-like temperature. In short, changing an environment can eliminate a lot of known survival skills for organisms, such as camouflage.
