Michael and Jose are studying about plate tectonics. They learned that plates usually move a few centimeters every year. They learned that the movement of heated material caused the plates to move. In which layer does the heated material move?

Answers

Answer:

Mantle layer

Explanation:

The movement of heated materials on the mantle layer of the earth helps in the movement of the tectonic plates. The earth is made up of four layers and they are the crust, the mantle, the outer core, and the inner core. The tectonic plates are always in motion which is very slow but constant.

The convection currents emanating from the mantle layer of the earth aids the movement of the tectonic plates. Natural disasters like earthquakes can result from the intense pressure emanating from the movement of the plates.

If you are neither relaxing or contracting a specific muscle, what is happening to the amount of ATP that is available in that muscle cell?

A. It is staying the same or increasing.
B. It is decreasing rapidly.

Answers

Answer:

A. It is staying the same or increasing.

Explanation:

The body tissues and cells require energy in the form of ATP to work, grow and move. It is produced from cellular processes like ETC, cellular respiration and other metabolic processes.

The amount of ATP in the cell:

Option A. It stays the same or increases.

The function of ATP can be explained as:

Muscle contraction and relaxation requires a certain amount of energy in the form of ATP. The insufficient amount will not be able to support the relaxation or the contraction of the muscle tissues.

In the condition where there is no contraction or relaxation the amount of energy will be the same or increased as it is not used in the process and remains constant.

Therefore, it remains the same or increases.

a man is twice as old as his son.Five years ago the ratio of their ages was 9:4.Find the sum of their ages​

Answers

Answer:

75years

Explanation:

Let the Father's age be represented by 2x

Let the Son's age be represented by x

Five years ago;

Man's age will be = 2x - 5

Son's age will be = x - 5

If the ratio of their ages five years ago was 9:4, then;

2x - 5/x-5 = 9/4

4(2x - 5) = 9(x - 5)

8x - 20 = 9x - 45

- Collect like terms

-20 + 45 = 9x - 8x

25 = x

Hence, the son's age = 25 years

If x = 25, the father's age (2x) will be 2 × 25 = 50years

The sum of their ages will be = 25years + 50years = 75years

5. Why are metamorphic rocks formed by contact metamorphism usually not as dense as those
formed by regional metamorphism?

Answers

Answer:

The rock was altered by high temperature with extreme pressure

Explanation:

Fossils would be destroyed

Metamorphic rocks formed by contact metamorphism are usually not as

dense as those formed by regional metamorphism because of their mode of

formation which involves a higher temperature without little or no pressure.

Contact metamorphism involves rock formation as a result of contact with

hot magma. The regional metamorphism involves the formation of rocks

deep in the soil through extreme temperature and pressure over a wider

area.

This is the major reason why the metamorphic rocks from  contact

metamorphism are denser than the  regional metamorphism.

In one type of dog, black spots (B) are dominant over brown spots (b) and long tails (L) are dominant over short tails (l). Use the dihybrid cross for parents with the genotypes BBLI and BbLl and determine , the like hood of offspring with the genotype

Answers

There is a possibility that the parents could get offspring with each genotype because each parent have each genotype. But offspring one usually almost always has dominant genes so their genes would be BBLl, like the parents. But let’s say the second offspring had the recessive gene pool. So their genes would be Bbll because not only do offspring take genes from the parents they can also get the genes from grandparents.

The principal RNA involved in protein synthesis is tRNA rather than the mRNA that is produced during transcription, which is carried from the nucleus into the cytoplasm to the ribosome. Thus, option C is correct.

What is a function of nucleic acids?

A DNA strand serves as a template for the construction of the RNA molecule during transcription. The protein synthesis process and DNA are connected by the RNA molecule.

The RNA molecule produced during transcription transmits data from the DNA to the machinery that makes proteins during translation.

Because they control the creation of proteins, nucleic acids—the primary information-carrying molecules of the cell—determine the inherited traits of every living creature.

Deoxyribonucleic acid (DNA) and ribonucleic acid are the two primary types of nucleic acids (RNA).

Therefore, carries amino acids that are bonded together to form proteins is not a function of nucleic acids.

A balloon is filled with helium in an airplane, where the air pressure is 81 kPa. The filled balloon has volume of 4.2 L. When the plane lands, the cabin is depressurized to the outside air pressure, which is 94 kPa. If the temperature of the balloon remains the same, what is the new volume of the balloon?

Answers

Answer:

3.62L

Explanation:

Using Boyle's law equation i.e

P1V1 = P2V2

Where;

P1 = initial pressure

V1 = initial volume

P2 = final pressure

V2 = final volume

According to information provided in this question, P1 = 81kPa, P2 = 94kPa, V1 = 4.2L, V2 = ?

P1V1 = P2V2

81 × 4.2 = 94 × V2

340.2 = 94V2

V2 = 340.2/94

V2 = 3.619

V2 = 3.62L

A cell removes a toxin it has produced through a chemical reaction. Which characteristic of living things is the cell demonstrating?


the ability to maintain homeostasis

the ability to maintain homeostasis

the ability to grow and develop

the ability to grow and develop

the ability to adapt and evolve

the ability to adapt and evolve

the ability to reproduce

Answers

Answer:

Sweating helps the human body maintain homeostasis by cooling the body when it starts to overheat so the internal temperature is kept more or less the same. When sweat evaporates from the skin, it uses up some of the excess heat energy on the skin, thus helping to keep the body cool.

According to cell theory, all living things are made of cells, and living cells come only from other living cells. Gene theory states that the characteristics of living things are controlled by genes, which are passed from parents to their offspring.

Sample answer: The concentration of oxygen in the atmosphere is maintained at 21 percent by a balance between two opposing processes: removal of oxygen from the atmosphere by most living things and addition of oxygen to the atmosphere by living things such as plants.

Sample answer: The human ability to sweat is an adaptation that helps maintain homeostasis in a hot environment by removing heat from the body when it evaporates. Like other adaptations, the ability to maintain homeostasis by sweating evolved by natural selection sometime in our evolutionary past.

a. Gene theory

b. Homeostasis

B

An adaptation is a trait that helps a living thing survive and reproduce in a given environment. Sample example. The chameleon’s ability to change color to match their background is an adaptation.

False

False

Humans began life as a single cell because we develop from a fertilized egg cell.

Gene theory states that genes are passed down from parents to their offspring. Genes determine the characteristics or traits of an organism. If these traits are particularly beneficial or adaptive, natural selection will cause the organisms with beneficial traits to produce more offspring compared to those without the beneficial traits. This results in a change in traits over time, which is called evolution.

No. Evolution is defined as a change in the characteristics of living things over time. Evolution through natural selection causes differences in the amount of offspring produced. Having offspring (or not) is, by definition, more than one generation.

Sample answer. I think that when ancestors of chameleons could change their color to match their background, they were less likely to be detected and killed by predators than those that couldn’t change their color. Therefore, the individuals that had the color matching ability were more likely to survive and reproduce than those that didn’t. This is an example of natural selection. Over time, this led to the population evolving the color changing ability, as those that didn’t have the ability died out.

Are eukaryotes more closely related to bacteria or to archaea? Explain.

Answers

Hello!

The Answer Is: Bacteria and Archaea are comprised exclusively of microorganisms; plants, mammals, and microorganisms such as fungi and protists are contained in the Eukarya. Because of their lack of a nucleus, the Bacteria and Archaea were grouped together and called Prokaryotes, but the Archaea are more closely connected to the Eukaryotes than to the Bacteria. The cell walls of bacteria contain a compound called peptidoglycan, while the cell walls of archaea do not. Archaea and bacteria also vary because the composition of the cell membranes of archaea is peculiar and does not contain the same lipids, or fats, present in other species' cell membranes.
