1.) great amounts of electromagnetic energy from our sun and other bodies in space travel through space. which is a logical conclusion about these electromagnetic waves?

their energy must be very low.

their frequency must be very low.

their wavelengths must be very short.

they can travel without a medium.

2.) the electromagnetic spectrum includes all electromagnetic waves, from radio waves with long wavelengths and low frequencies to gamma rays with short wavelengths and high frequencies. which statement best describes how fast these waves travel in a vacuum?

gamma rays travel much faster than others because they have the highest frequencies.

high-frequency waves travel somewhat faster than low-frequency waves.

all electromagnetic waves travel at the same speed.

infrared waves travel faster than ultraviolet waves.

3.)when being exposed to the sun for long periods of time, your body may absorb small amounts of ultraviolet radiation. one way to reduce your exposure and absorption of ultraviolet radiation would be to wear uv-blocking sunscreen.

Chapter 11.1 & 11.2 notes section 11.1 1. every living thing has a set of ? inherited from its parents. 2. after becoming a ? , mendel spent several years studying ? and mathematics at the university of vienna. 3. during sexual reproduction, male and female reproductive cells join, a process known as ? . 4. pea flowers are normally ? , which means that sperm cells in pollen fertilize the egg cells in the ? flowers. 5. when mendel crossed plants with ? characters for the same trait, the resulting offspring had only one of the characters. 6. a ? is a specific characteristic, such as seed color or plant height, that varies from one individual to another. 7. filius and filia are the latin words for ? and ? . 8. the offspring of crosses between parents with different traits are called ? . 9.to mendel's surprise, all of the offspring had the character of only ? of the parents. 10. mendel's first conclusion was that biological inheritance is determined by ? that are ? from one generation to the next. 11. scientist calls the chemical factors that determine traits ? . 12. mendel's second conclusion is the ? . 13. the principle of dominance states that some alleles are ? and others are ? . 14. when mendel allowed the f1 plants to reproduce by self-pollination the traits controlled by ? alleles reappeared in about ? of the f2 plants in each cross.

The first generation of offspring from the cross of two parents is called the a. f1 generation b. f2 generation c. short generation d. p generation

Which type of respiration takes place when there is no oxygen present? a. anaerobic b. mitochondrial c. cellular d. aerobica. anaerobic
