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.

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).

Sensory neuron(s) then transmit information from the sensory receptor(s) to the Central Nervous System
Explanation:
These receptors are located all over the body but some types of receptors are in specific areas of the body (e.g. taste receptors in the mouth).
Sensory neuron(s) then transmit information from the sensory receptor(s) to the Central Nervous System (i.e. the brain and spinal cord, sometimes referred to in the abbreviated form: C.N.S.). This is happens because peripheral nerves all connect to the spinal cord via the network of nerves within the nervous system.
The information so received by the C.N.S. is further transmitted by relay neurone(s) with the C.N.S.

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.

in humans, normal people are dominant (X) to people with x-ray vision. If a mutant with x-ray vision has a child with a woman heterozygous for x-ray vision what is the chance that one of their children will have x-ray vision?
Answer:
2/4 or 50%
Explanation:
Heterozygous means the organism has two different alleles, so the genotype of the woman is Xx
The mutant's genotype is xx, because in order for a recessive trait to be expressed, there needs to be two recessive alles
Use the genotypes of the parents to create a punnett square (shown in image) to find the possible genotypes of their children
To chance of a phenotype is determined by how many of the possible genotypes will express the phenotype of x-ray vision and how many genotypes there are in total. The chance can be presented like this:
2/4
2 is the number of x-ray children
4 is the total number of children
To find the percentage you can do 2 ÷ 4 × 100
And that will give you the answer of 50
So the percentage is 50%

Why do you think Europeans—and especially the English—are most affected by asthma?
Answer: Asthma is one of the most frequent chronic conditions in Europe, affecting more than 30 million Europeans – a number that is still growing.
"At some stage in the future almost half of the population may suffer from an allergic disease and asthma will be a considerable proportion of this," said Nikolaos Papadopoulos, professor of allergy and pediatric allergy at the University of Athens, in an interview. He added that it is also a global phenomenon.
Asthma is a chronic disease of the airways that makes breathing difficult. An asthma attack inflames and narrows the airways that carry oxygen to the lungs, leading to coughing, wheezing, shortness of breath, and chest tightness. Its prevalence has been linked to industrial development.

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
