How would you calculate the distance of a paper airplane
Answer: uh Well, Your foot should be at the end of the starting line you prepared earlier. Once you're ready, you can throw your plane. Measure the distance the paper plane traveled (in centimeters or meters) from the starting point with the tape measure. Your lab notebook should include this data in a table. "Plane 1" will take off from this point.

What factors influence ocean water density?
Answer:
Salinity, temperature and depth all affect the density of seawater. Density is a measure of how tightly a certain amount of matter is packed into a given volume. The more the stuff is packed in, the higher the density. Density can be calculated by dividing an object's mass by its volume.
Explanation:
Case Study The Selkirk Rex cat is a breed known for its curly hair. The allele responsible for this curly hair exhibits incomplete dominance. Two copies of the allele yields very curly hair, a slender body, and large ears. One copy of the allele yields a more sturdy body, wavy hair, and smaller ears. Cats with one copy are preferred for professional cat shows. A man from Argentina recently inherited two sister Selkirk Rex cats from a relative and is interested in breeding them to produce more curly-haired cats. One cat carries two copies of the Selkirk allele. The other Selkirk Rex cat carries one Selkirk allele. What genotypes should he seek in mating partners for his cats to produce the most heterozygous kittens possible in the next generation? Note: he doesn't want any kittens that do not have wavy or curly hair. What genotypes should the breeder choose for mates for his Selkirk cats? Choose the beſt answer from the choices below to maximize the number of heterozygous kittens AND maintain the mutation in the population for future breeding. For the SS cat, he should choose Ss. For the Ss cat, he should choose 55. For the SS cat, he should choose ss. For the Ss cat, he should choose Ss. For the SS cat, he should choose 55. For the Ss cat, he should choose Ss. For the SS cat, he should choose ss. For the Ss cat, he should choose SS.

Of the terrestrial planets, Earth and Venus are
Which phrase best completes the sentence?
O about the same size
O different in density
O similar to gas planets
O very different in size
Answer:
A. About the same size
Explanation:
Venus is often named as Earth's twin because both worlds share a similar size, surface composition and have an atmosphere with a complex weather system. Both planets have almost the same size and density.
Hope this helps!
Earth and Venus are about the same size. So, the correct option is (A).
What is Earth?Earth is the third planet from the Sun and the only celestial object known to harbor life. Only Earth maintains liquid surface water in the Solar System. About 71% of Earth's surface is made up of ocean, which dwarfs Earth's polar ice caps, lakes, and rivers.
Earth consists of land, air, water and life where land consists of mountains, valleys and flat areas and air is composed of various gases, mainly nitrogen and oxygen. Water includes oceans, lakes, rivers, streams, rain, snow, and ice.
Venus is known as our sister planet because of the similarity in size, mass, density, and volume that both planets are believed to share a common origin at the same time from a condensed nebula about 4.5 billion years ago.
Thus, Earth and Venus are about the same size. So, the correct option is (A).

Explanation:
If 575,250 calories of energy are available at the first trophic level, calculate the number of calories available to the 2, 3 and the 4 level
Answer: See explanation
Explanation:
The trophic level of an organism simply refers to the position that is occupied by an organism in a food web. It should be noted that in the next trophic level, only 10% of the energy will be available. Therefore,
1st trophic level = 575,250 calories of energy.
2nd trophic level = 575,250 × 10% = 57525 Calories of energy.
3rd trophic level = 57525 × 10% = 5752.50 Calories of energy
4th trophic level = 5752.50 × 10% = 575.25 Calories of energy

1 7.1.2 Exam: Semester Exam Question 36 of 42 What tends to happen to a sound wave as air temperature increases? O A. The wave's speed decreases. B. The wave stands still. . O C. The wave vibrates more slowly . D. The wave's speed increases
Answer:
D
Explanation:
The wave's speed increases when air temperature increases. Therefore, option (D) is correct.
What are sound waves?As air temperature increases, the speed of sound waves in air also increases. This is because air molecules move more quickly at higher temperatures, and the faster-moving molecules can transmit the sound energy more quickly. As a result, sound waves will travel faster through hot air than through cold air.
Conversely, as air temperature decreases, the speed of sound waves in air will decrease as well. This property of sound waves can have practical implications, such as in designing concert halls or sound systems where the temperature of the air needs to be taken into account in order to achieve optimal sound quality.

What do you think would happen if producers did not exist ?
Many snakes and lizards live in the desert, where temperatures are high during the day and cold at night. How does the temperature range affect the size of the snakes and lizards?
A. High daytime temperatures allow them to grow as large as the food supply will allow.
B. Cold nighttime temperatures limit their size, because large ectotherms need a long time to warm up in the sun.
C. High daytime temperatures limit their size, because large endotherms would overheat on very hot days.
D. Cold nighttime temperatures limit their size, because large endotherms would lose too much of their body heat.
Answer:
A. High daytime temperatures allow them to grow as large as the food supply will allow.
Explanation:
Snakes and lizards are cold-blooded animals. This type of animal cannot maintain a constant body temperature and depends on the temperature of the environment to keep warm and keep its organs and metabolism working.
Room temperature is so important to these animals that they even determine the size of their bodies. For these animals, high temperatures allow them to have their metabolism accelerated, so they can grow as much as the availability of food allows. On the other hand, if there is not enough food, or very cold temperatures, they will need to be smaller in size, as the metabolism will be slow.
