14. Karim brings a chair from the backyard into his house and is going to stack it on top of another chair. Both chairs are the

same size and have the same number of molecules. The diagram above shows the chairs before they touch. Use the information in the diagram to answer the question.
How does the temperature of the bottom chair compare with the temperature of the top chair before the chairs touch? What will happen after the chairs have been touching for a while?

a Before the chairs touch, the bottom chair is cooler than the top chair. Once the chairs are touching, the top chair will transfer kinetic energy to the molecules in the cooler bottom chair until both chairs reach the same temperature, which will be in between their starting temperatures.

b Before the chairs touch, the bottom chair is hotter than the top chair. Once the chairs are touching, the bottom chair will transfer kinetic energy to the molecules in the cooler top chair until both chairs reach the same temperature, which will be in between their starting temperatures.

c Before the chairs touch, the chairs are different temperatures. Once the chairs are touching, both kinetic energy and cold energy will transfer between the molecules in the two chairs until both chairs reach the same temperature, which will be in between their starting temperatures.

d Before the chairs touch, the bottom chair is hotter than the top chair. Once the chairs are touching, the cooler top chair will gain kinetic energy until the molecules in both chairs have an energy of 35, because hotter things increase the temperature of cooler things.

Is a superficial fungal infection found on the head.
Marianna [84]

Answer:

Option B, Tinea capitis

Explanation:

Superficial fungal infection of skin of head or scalp is known as Tinea capitis.

These fungal infection attack the hair shafts and follicles and is a superficial form of mycosis or dermatophytosis.

Tinea cruris is the superficial infection of genitals, buttocks and inner thighs regions. Hence, option A is incorrect.

Tinea pedis is the superficial infection of foot and regions between the phalanges. Hence, option C is incorrect.

Tinea corporis is the superficial infection of arms, legs or skin. Hence, option D is incorrect.

Thus, option B is correct.

- For plants and other organisms to develop differences among their respective species the alleles of their genes must contain
andre [41]

Explanation:

Mutations increase variation within a population.

During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:

  • somatic: these only occur within certain cells, and arise from environmental factors such as UV light
  • hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.

Further Explanation:

During reproduction other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.

Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism.Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.
