Why do waves that travel through basalt have a higher velocity than a wave traveling through sand?

Answers

Answer 1

Answer:

Read Explanation

Explanation:

Even though the technology does not exist to travel into all of Earth’s layers, scientists can still learn a great deal about Earth’s structure through seismic waves. Seismic waves are vibrations in the earth that transmit energy and occur during seismic activity such as earthquakes, volcanic eruptions, and even man-made explosions. There are two types of seismic waves, primary waves and secondary waves. Primary waves, also known as P waves or pressure waves, are longitudinal compression waves similar to the motion of a slinky (SF Fig. 7.1 A). Secondary waves, or S waves, are slower than P waves. The motion of secondary waves is perpendicular to the direction of the wave travel, similar to the motion of vigorously shaking a rope

Small frogs living in a marshy region feed on small insects in the region. The relationship between the frogs and insects is a _____ relationship. A particular species of lizards is introduced into the marshy land. These lizards also start feeding on these insects. The introduction of lizards may lead to ____________ .  

1. a) commensal-host

b) parasite-host

c) prey-predator  

2. a) competition between lizards and frogs for food

b) an increase in the number of frogs

c) no population change in any of the three species

Answer:

1. c) prey-predator  

2. a) competition between lizards and frogs for food

Explanation:

1. Frogs feeding on small insects in the region shows prey-predator   relationship. Predators are the dominating organism which kill weak organism for food and preys are the organisms which are killed. Here, frogs are the predators and small insects act as prey.

2. Introduction of lizards in the same region will increase the competition between lizards and frogs as their food is same that is small insects. Both frogs and lizards have same source of food (small insects), so lizard and frogs will fight for the same food.

Hence, the correct answers are 1. c) prey-predator  

2. a) competition between lizards and frogs for food .

Answer:

The relationship between the frogs and insects is a

prey-predator relationship. A particular species of lizards is introduced into the marshy land. These lizards also start feeding on these insects. The introduction of lizards may lead to competition between lizards and frogs for food

Incomplete dominance

Inheritance of characters are based on Mendelian principle. According to it, the blending of phenotype is called incomplete dominance.

What is Mendelian principle?

Gregor Mendel is known as father of modern genetics. For this Mendel performed experiment on pea plant.

The main principles of Mendelian genetics can be stated as follows:

Law of Independent assortment.Law of dominance.Law of segregation.

When different alleles of parents blend to form a mixed colored organism, this is referred as incomplete dominance.

5. If there is a large number of prey rodents, the number of owls will increase due to a healthy
food source. More owls feeding on the rodents will cause their population to decrease, which in
turn will eventually cause the owls number to decrease. Would you expect to find this pattern in other ecosystems between predators and prey? Explain.

Answers

Answer:

Yes

Explanation:

One would expect to find the same pattern in any other ecosystems between predator and prey unless there is a way the prey's population is being replenished.

When predators start hunting down preys, the population of preys start decreasing and this will in turn means less food for the predators. If the trend continues, competition for food become fierce among the predators and this will make their population to start decreasing as the competitively strong ones take over the little food that remains and the competitively  weak ones are gradually left to starve to death.

Most scientists agree that saturated fats contribute to high levels of “bad” cholesterol, while monounsaturated fats and polyunsaturated fats lower this type of cholesterol. The table below shows data about fats in some common foods.

Food (14 g) Saturated fat (g) Monounsaturated fat (g) Polyunsaturated fat (g)
Canola oil 1.0 8.9 3.9
Margarine 1.6 5.4 3.4
Olive oil 1.9 9.9 1.4
Lard 5.0 5.8 1.4
Butter 7.9 3.7 0.5

Joyce and Linda are identical twins who are 50 years old and enjoy exercising daily. Joyce avoids eating any dairy or animal products and eats granola made with canola oil for breakfast. Linda prefers rich foods, and eats bacon, eggs, and buttered toast each morning. Which statement describes a logical inference that can be made from the provided information?

a)Butter has higher levels of saturated fats in it than canola oil.
b)Linda and Joyce both have high levels of “bad” cholesterol.
c)Butter contains a small amount of polyunsaturated fats.
d)Linda has a higher level of “bad” cholesterol than Joyce.

Answers

Answer: D: Linda has a higher level of "bad" Cholesterol than Joyce

Explanation: From the first sentence Saturated fat contributes to high level of bad cholesterol. Buttered food, bacon ( Lard) are significantly high in saturated fat which contributes to high level of bad cholesterol and that's what Linda is eating. Joyce on the other hand avoids animal products and feeds on granola from Canola oil which is low in saturated fat.

The logical conclusion base on this diet is Joyce has low level of bad cholesterol while Linda has high level of bad cholesterol

4. If you are male, which member of your family should you look at to tell whether you are going to
go bald? Why? Use a punnett square to prove your answer.

Answers

Answer:

Your mother

Explanation:

If you are a male, the member of the family you should look at to tell whether you are going to go bald is your mother.

Baldness is a sex-linked recessive trait and as such, the two X chromosomes in females need to carry the allele in order for females to be phenotypically affected for the disorder. The males having only one X chromosomes however, means that they only need that single X chromosome to carry the baldness allele in order for them to be affected for baldness.

Assuming the allele for baldness in represented by b. Your mother is affected for baldness while your father is free from the disorder. This means that the genotype of your mum would be [tex]X^bX^b[/tex] while that of your dad would be [tex]X^BY[/tex]. According to law of inheritance, males usually inherit their X chromosomes from their mother. This means that any male your mother gives birth to would have the genotype [tex]X^bY[/tex] which phenotypically means that they will be affected for baldness.

The attached image shows the Punnet's square analysis of what will happen during inheritance.

A red blood cell placed in distilled water will swell and burst due to the movement of Your answer: salt from the distilled water diffusing into the cell water molecules moving by osmosis into the cell water from the red blood cell moving into the distilled water

Answers

Answer:

Due to the movement of surounding water ijnto the cell.

Explanation:

A red blood cell placed in distilled water will swell and burst due to the movement of - water molecules moving by osmosis into the cell.

Osmosis is the movement of water that diffuses from a higher water concentration area to a lower water concentration area.

The distilled water outside the red blood cell, since it is 100% water and no salt, is hypotonic to the red blood cell.The red blood cell will gain water, swell ad then burst.

Thus, a red blood cell placed in distilled water will swell and burst due to the movement of - water molecules moving by osmosis into the cell.

The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. yellow pods are the dominant trait. The flowchart is missing the labels that describe the traits.

In which squares should the phrase “yellow pods” appear?

1. A and D

2.B and E

3. A, C, and D

4. A, B, C, D, and E

Answer:

The correct answer is: 3. A, C, and D

Explanation:

According to Mendel’s laws of inheritance, when a plant with the dominant trait is crossed with a plant with a recessive trait, as a result, the dominant phenotype appears in all the F1 offspring. On Self cross F1 offspring, produces F2 offspring with dominant and recessive traits.

In the given scenario, pea plant with ‘yellow pods’ are dominant and pea plant with ‘green pods’ is recessive.

Therefore, when pea plant with yellow pods is crossed with the pea plant with the green pod, the F1 offspring (C) produced are with yellow pods.

Thus, parent (A) is with yellow pods and F2 offspring (D) is with yellow pods.
