The answer is C. Thermal energy is transferred to her face by radiation, and thermal energy is transferred to the bottoms of her feet by conduction.
Conduction is a method of transferring heat by using the collision of molecules and free electrons (depending on the material). Heat is usually transferred by conduction if both objects are in contact with each other that way the molecules can collide and spread the kinetic energy thus raising their internal heat. So, since the feet and the sand are in contact, so the heat should be transferred by conduction. However, air is a very poor heat conductor, it cannot transfer heat efficiently, therefore, the first answer is not conduction.
Radiation is a method of transferring heat too but using electromagnetic waves. It works great even in the air, or even with vacuum space. The sun shining from outer space to earth through the vacuum space is also by radiation. So, the first answer is radiation.
The answer is C, hope it helps!
Hi There!
1. a. Toxicodendron
2. c. Eukaryotes
3. a. Felis domesticus
4. b. Plantae
5. a. Protist
6. While protists are unicellular eukaryotes can be both single or multicelled. Most protists have special organelles and a nuclear membrane which differs from bacteria.
Hope This Helps :)
Gene. A segment of a DNA molecule that codes for a particular protein and determines the traits of the individual. A gene is the basic unit of heredity in a living organism

Answer:
What will happen to the population of mice that it will keep growing at a tremendous rate without a fear of being caught by a predatory. This will increase the population curve of mice but will decrease the population curve of the cat at similar speed.
What else can happen is that cats will no longer be depending on Mice for their food and they will be finding some alternate food host.
What else can happen is the trait of tailless cannot be favored by environment as proposed by Lamarack in his theory of evolution that if organism acquires some favorable trait during his life then it is possible that he will pass this trait to offspring. Though this trait is not naturally induced therefore, there are no chances that tailless mice can born and nature choose it as a favorable trait.
In 1880 August weismenn did experiment of similar nature, he cut off the tails of 20 successive generations of mice abut not a single tailless mouse was born. Therefore, he proved that until nature selects some traits, they are not that easily passed from one generation to another if induced by human.
Conclusion: <em>Therefore, after 50 generation mice will be just like parent mice with tails however they will have good population and less predators.</em>
Hope it help!
