If different masses of water are heated to the same temperature, the sample that will absorb more energy will be the mass of water with the greatest amount of water mass, because the larger the material, the greater the amount of heat needed.

<h3>What is the specific heat of water?</h3>

Water has a specific heat of 1 cal/g. ºC This means that the energy of 1 cal is required for a variation of 1 °C in 1 g of water.

With this information, we can conclude that Water's specific heat power is 4.2 joules per gram per Celsius degree or 1 calory per gram per Celsius degree.

What are constants or controlling variables in an experiment? What would be some constants from the experiment mentioned above?
lawyer [7]

Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.

Xelga [282]

Answer:

mitosis

Explanation:

The cellular process that enables the cells to grow and develop into tissue is mitosis.

Mitosis involves the division of the vegetative cells of the body and is important for the growth and development of organisms as well as in the healing of wounds or the replacement of damaged cells/tissues.

<em>Hence, in treating burns and other types of skin injuries, the cells of the skin are stimulated to divide rapidly by </em><em>mitosis</em><em> so as to replace the damaged cells due to the injury. By doing so, the injured area heals.</em>

Suppose a plant breeder wants to isolate mutants in tomatoes that are defective in DNA repair. However, this breeder does not ha
Nana76 [90]

The provided question has marked options incorrectely the correct order as follows:

A) Expose putative DNA repair mutant plants to ionizing radiation L and see if they survive less well than wild-type plants.

B) Measure the amount of post-translational processing that occurs in the putative DNA repair mutant plants.

C) Measure the somatic mutation rates for the putative DNA repair mutant plants.

D) Expose the putative DNA repair mutant plants to a deaminating agent and select those that have a decreased mutation rate.

E) Measure the germline spontaneous and induced mutation rates for the putative DNA repair mutant plants.

Answer:

The correct answer is: A), C) and E)

Explanation:

The breeder wants to isolate the mutants in tomatoes that are defective in DNA repair, to identify such plants breeder should follow these methods as they will allow best to identifying the defective tomatoes-

Measure the somatic mutation rates for the putative DNA repair mutant plants.

Measure the germline spontaneous and induced mutation rates for the putative DNA repair mutant plants.

Expose putative DNA repair mutant plants to ionizing radiation L and see if they survive less well than wild-type plants.  This will allow the breeder to see and analyze the ability of DNA repair in tomatoes
