3. What does the Earth's magnetic field reveal about the structure of the Earth's layers?
That the outer core is solid.
That the outer core is liquid.
That the mantle is solid.
That the mantle is liquid.

Answers

Answer 1

Answer:

The above answer is correct. The answer is That the outer core is liquid.

Answer 2

The Earth's magnetic field reveals the structure of the Earth's layers and the outer core is liquid. Thus, the correct option for this question is B.

What is the principle of magnetic field reveal about the earth?

The principle of earth's magnetic field states the production of attraction by the motion of molten iron in Earth's core, the magnetic field protects our planet from cosmic radiation and from the charged particles emitted by our Sun. It also provides the basis for navigation with a compass.

The magnetosphere is the region that is located above the ionosphere that is defined by the extent of Earth's magnetic field in space. The Earth is composed of layers having different chemical compositions and different physical properties.

The crust of the Earth has some permanent magnetization, and the Earth's core generates its own magnetic field, sustaining the main part of the field we measure at the surface.

Therefore, the Earth's magnetic field reveals the structure of the Earth's layers and the outer core is liquid. Thus, the correct option for this question is B.

Table salt and table sugar, examine the chemical formulas for salt and sugar. What do they tell you about what type of bonding is present in each compound

Answers

Answer:

Explanation:

Table salt, also NaCl (sodium chloride) is an ionic compound in which there is a transfer of an electron from the sodium atom to the chlorine atom. This electron transfer is characteristic of an ionic/electrovalent combination/bonding. While table sugar, also C₁₂H₂₂O₁₁ (sucrose) is an organic compound; thus has covalent bond within it's carbon chain, carbon-hydrogen bond and carbon-oxygen bond. Covalent bonding involves the sharing of electrons between two atoms, these electrons that are shared are referred to as "shared pair".

Answers

Answer:

Path: Atmosphere -> Ocean -> Shells -> Limestone -> Cement Plant  

The path of a carbon atom is - air, ocean, shells/coral reef, limestone, cement plant.

Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron, and other ingredients.

Common components used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace, silica sand, and iron ore.Limestone form the coral reefs that are massive structures deposited by coral polyps.Coral reefs get their carbonate from the ocean that comes from air Carbon in limestone is produced in a cement plant when heated to make calcium oxide. The waste product is carbon dioxide.

In the diagram below, which cells are involved in the process of sexual reproduction? A.) cell 3, only B.) cell 1 only C.) cell 1 and 2 D.) cell 2 and 3

Answers

C I’m sorry if it’s incorrect

Cell 1 and 2 are involved in the process of sexual reproduction which are sperm and egg respectively.

What are gametes?

Gametes are reproductive cells that are responsible for sexual reproduction. In animals and plants, gametes are typically specialized cells that are specifically designed for the purpose of reproducing and transmitting genetic information from one generation to the next. Gametes are produced by the process of gametogenesis, which is the process of forming and developing gametes.

In animals, gametes are typically either eggs (ova) in females or sperm in males. Eggs are large, non-motile cells that contain a large amount of cytoplasm and nutrients to support the development of an embryo. Sperm are smaller, motile cells that are specialized for fertilization and are capable of swimming through the female reproductive tract to reach the egg.

In plants, gametes are typically produced by specialized cells called gametophytes. Gametophytes produce gametes through a process called meiosis, which is a type of cell division that results in the production of four genetically diverse daughter cells. The gametes produced by gametophytes are typically small and non-motile, and they are capable of fusing with gametes from other plants to produce a fertilized egg, or zygote.

It is magnified 2000 times.

We need to find the diameter of the image seen through the microscope in millimeters.

The size of the diameter is given by :

Clouds with light rain.

In your current location, the weather is much like this picture: cloudy and drizzly. The weather has been like this for several days. The good news is that the weather report says warmer weather is coming soon.

Which type of front most likely caused this weather?

occluded front
stationary front
warm front
cold front

Answers

Warm fronts move more slowly and are less violent than cold fronts. They are associated with warm air moving over cold air and are more likely to produce large regions of light to moderate rain, drizzle or snow. Cirrus clouds and alto cumulus, along with fog, often precede warm fronts as they move through an area. The milder weather that follows will be warmer in temperature. So it would be warm fronts.

Which of the following statements DOES NOT accurately describe the experimental design used by Fred Griffith?

A.The type of bacteria injected into the mouse was the independent variable in his experiment. B.The injection of the live rough bacteria into the mouse is a control because it was used as a standard of comparison for other experimental setups.
C.The dependent variable in the experiment was the health of the mouse after injection.

Answers

Answer:

The correct answer is B. It is false that the injection of the live rough bacteria into the mouse is a control because it was used as a standard of comparison for other experimental setups.

Explanation:

The experiment conducted by Frederick Griffith in 1928 was one of the first experiments to show that bacteria could transfer genetic information.

Griffith used two slightly different pneumococcal strains in his experiment. One of them was harmless to the mice, while the other was not. Using each strain separately, the logical thing happened: the mice died with the fatal strain, and nothing happened with the harmless.

Then, Griffith killed the deadly strain, and mixed both strains, introducing them into the mice. After this, the mice died, which allowed us to verify that the bacteria can transfer genetic material even after dying, through the transformation process.

Answers

Answer: 1. Net primary productivity

2. there will be less organic matter available

3. it decreases

4. ethanol

5. there isn’t enough energy available to support secondary consumers

Explanation:

1. Gross Primary productivity is the organic material that is left after subtracting energy used for respiration. It is always greater than net primary productivity.

2. There will be less organic matter available for the mouse because plant is a primary producer of biomass and it lies at the lowest trophic level as we go up in the trophic level the level of energy reduces.

3. The biomass will decrease while going from lower to higher trophic levels this is because of the fact that the plants or other autotrophs are the primary producers of biomass.

4. The incomplete combustion of gasoline and methane are the major fuels contributing to global warming.

5. There are less secondary consumers in an ecosystem because more tertiary consumers are dependent on secondary consumers for their food and energy requirements.

Explanation:

humans have 2 sets of 23 chromosomes

Two full sets of chromosomes make up a diploid cell. Humans mostly have diploid cells, which have 23 pairs of chromosomes each, for a total of 46 chromosomes.

What are chromosomes?

There are 22 pairs of autosomes and two sex chromosomes in this. The person received one copy of each pair of chromosomes from their mother and the other copy from their father.

A "diploid cell" is one that has two copies of each chromosome; human somatic cells are diploid and have 46 chromosomes, 22 pairs of autosomes, and a pair of sex chromosomes.

Histones, which function as packing proteins for the majority of eukaryotic chromosomes, join forces with chaperone proteins to attach to and compress the DNA molecule, maintaining the integrity of the molecule.
