Typically, most merit-based aid scholarships are offered to students based on _____.

Answers

The right answer is academic achievement.

At any age, children have behaviors that adults would like to see changed. In both schools and private practice, many educators and psychologists use reward systems to help them achieve this.

Reward systems can take different forms: motivation chart, token bags, reinforcement techniques.

They are offered to students based on their GPAs; one way of measuring merit in schools. Merit-based scholarships help school children out of worse economic environments where money is not abundant to gain a opportunity to get into a good college based on their good grades. 

How does mass extinction affect species that survive?There are no surviving species if a mass extinction occurs.

They will soon become extinct.

They combine gene pools.

They fill new roles in the changed environment.

Answers

When there is a mass extinction, species that survive will combine gene pools. A gene pool is the sum of population of same species have the same genetic material. Those species that survived will combine for them to survive from extinction. If there is a combination of gene pool then there will be a possibility that evolution will happen

The mass extinction may cause the arrival of new species in the new and changing environment.

Further Explanation:

Mass extinction is the phenomenon when there is the extinction of many organisms or the group of an organism from the Earth due to change in environmental condition as it would not allow the survival of these organisms in the new environmental condition. This may cause the appearance of a new organism or the spread of mutant organisms in the prevailing environment that may play new roles. Hence new kind of ecosystem may be formed in the changing environment and those organisms that survive or get adapted to this condition may reproduce more and increase in number.

Therefore mass extinction although causes removal of some organism but may provide a new platform for the arrival of new kind of species and formation of a new ecosystem.

A student was visiting a friend at her home. Her friend owned two cats. After playing with the cats fora while, the student began to sneeze. Her nose began to run and her eyes became red, watery, and
itchy. It also became hard for her to breathe. A few minutes after leaving her friend’s home, the
symptoms disappeared.
Provide a biological explanation for the symptoms the girl developed at her friend’s house. In your
response, be sure to:
• state one reason why her symptoms are not likely due to an infectious agent

Answers

Answer: This girl is allergic to cat´s hair.

Explanation:

The substance that provokes allergy to cats is a protein produced in the sebaceous glands and that can be found in the cats´ hair. It can be found in clothes, walls, beds, among other places. As it can also be suspended in air, a person can easily breathe it.  In a house with cats, these proteins are present in important amounts.

An allergic reaction is an abnormal response of the immunity system to a substance considered strange to the body, in this case, the protein or the cat´s hair.  These strange substances are called allergens.

The allergen gets in contact with the body for the first time in a sensibilization face. The immunity system considers that this is a strange dangerous substance for the body. In this first stage, the subject submitted to the presence of the allergen does not show any symptoms. But in a second contact, the organism reacts with allergic reactions.

There might appear symptoms in ayes and nose as irritations, stinging, cough, skin´s eruptions and difficulty to breath.

beacuse she must have a cat hair near her nose and it ismaking her sneeze

The Celsius temperature scale is also something called the centigrade scale. Why is this?

Answers

There are three temperature scales in use today, Fahrenheit, Celsius and Kelvin.

Fahrenheit temperature scale is a scale based on 32 for the freezing point of water and 212 for the boiling point of water, the interval between the two being divided into 180 parts. The 18th-century German physicist Daniel Gabriel Fahrenheit originally took as the zero of his scale the temperature of an equal ice-salt mixture and selected the values of 30 and 90 for the freezing point of water and normal body temperature, respectively; these later were revised to 32 and 96, but the final scale required an adjustment to 98.6 for the latter value.

Until the 1970s the Fahrenheit temperature scale was in general common use in English-speaking countries; the Celsius, or centigrade, scale was employed in most other countries and for scientific purposes worldwide. Since that time, however, most English-speaking countries have officially adopted the Celsius scale. The conversion formula for a temperature that is expressed on the Celsius (C) scale to its Fahrenheit (F) representation is: F = 9/5C + 32.

A hypothesis does all of the following EXCEPT A) attempt to answer the question

B) be evaluated through experimentation

C) a be refined after evolution

D) acts as a universal principle

Answers

 D) acts as a universal principle

It's D because a hypothesis is just an educated guess(sort of) of what you think happens.  A universal principle is the exact opposite of that.


D)
Because a hypothesis is an "Educated Guess" so it obviously cannot be a principal that is used in Science. For Example, I could say my hypothesis on Men and Women is that Women are smarter. This is not necessarily true because I don't have any facts yet. In order to discover the answer, I must A) Attempt to answer and see if this is true, B) Evaluate this by doing experiments, and C) I must change my hypothesis so it is correct. I cannot say this is a "Universal Principle" by stating it.
Hope I helped :-)
