Help Me Question 6 The layers of Earth are the crust, mantle, and core, with the core being divided into inner and outer layers. Which of the following does NOT describe the layers of the solid Earth? The core makes up the majority of Earth's volume. The mantle is composed of rocks known as silicates. The core is made up of dense elements, such as iron and nickel. The crust is extremely thin when compared to the core or mantle.
Answer: The core makes up the majority of Earth's volume.
Explanation:
The core does not make up most of the earth's volume. So this is the wrong statement. Hence the correct option is A.
What are the layers of the earth?The earth is an irregular solid sphere divided into four major layers. The outermost layer is the crust. After that, there is the mantle and then there is the core. The core is separated into the outer core and the inner core.
The top layer of the earth we see and live on is the crust of earth. The crust is only 40 km and thus makes the thinnest layer of the earth. The crust is of two types. First is the continental crust which is the thick land. The oceanic crust is found deep at the bottom of the ocean.
The mantle is 2890 km and is the thickest layer of the earth. It makes for 84% of the earth's volume. The mantle is divided into several layers based on their seismological properties.
The core is divided into 2 layers: the inner core which is solid and the outer core which is liquid. The inner core has a radius of 1220 km and the outer core has a radius of 3400 km.
Thus the mantle makes up the majority of the earth's volume.
Therefore the correct option is A.

Hypernatremia is a condition that can occur in anyone, especially athletes. It’s also a situation that can occur where people do not have drinking water. Normally it does not require hospitalization and can be resolved by doing a simple thing we all do every day. What can correct this condition in a normal, healthy person?
Answer:
The correct answer is - drinking more water and fluid.
Explanation:
Hypernatremia is a condition in which the body losses too much water or body fluid and the case of dehydration took place which leads to the low serum sodium concentration. The serum sodium concentration is under 145 mmol/L in this condition.
This occurs due to loss of body fluid due to sweating, diarrhea injury, or drinking very little water. To correct or treat this treatment in a healthy person it is asked to drink plenty of water and other fluids to maintain body fluids.
Hypernatremia is a medical condition that occurs when an individual doesn't
take water . It is also caused by increase in sodium levels and a
corresponding decrease in the water levels.
This condition have characteristic symptoms such as extreme thirst,
unconsciousness, weakness and death in severe conditions .
The condition can be corrected by intake of a lot of water every day so as to
help maintain a concentration equilibrium in body fluids.

Which properties are characteristics of nonmetals? Check all that apply.
malleable
brittle
solid at room temperature
low density
O electrical insulator
thermal conductor
The properties of nonmetals include brittleness, being solid at room temperature, low density, electrical insulating ability, and being poor thermal conductors.
Nonmetals possess certain distinct properties. Let's examine each option to determine which ones apply.
Malleable: This property refers to the ability of a material to be hammered or pressed into different shapes without breaking. Nonmetals are generally brittle, meaning they are not malleable. Therefore, this property does not apply.Brittle: Nonmetals are known for their brittleness. They tend to fracture or break when subjected to stress, making this property characteristic of nonmetals.Solid at room temperature: While some nonmetals can exist in the gaseous or liquid state at room temperature, many nonmetals are indeed solid. Therefore, this property applies.Low density: Nonmetals typically have lower densities compared to metals. This property is commonly associated with nonmetals, making it applicable.Electrical insulator: Nonmetals are poor conductors of electricity, and they can act as insulators. This property applies to nonmetals.Thermal conductor: Nonmetals generally have low thermal conductivity, meaning they do not conduct heat effectively. Therefore, nonmetals are not good thermal conductors. This property does not apply.In summary, the properties characteristic of nonmetals include being brittle, solid at room temperature, low density, and acting as electrical insulators

Chickpeas are the third largest legume crop in the world and one of the eight founder crops of agriculture. Chickpea flower color is a useful morphological marker of different strains of chickpea. Of the world collections of chickpeas, 80% produce pink flowers, 19% produce white flowers and 1% produce blue flowers. Two pure-breeding strains of chickpea, Strain A (white flowers) and Strain B (blue flowers) were crossed and the F1 were all pink. The F2 generation (from an F1 X F1) produced: 141 Pink flowers plants 40 Blue flower plants 66 White flower plants A. Explain these results if a single gene is responsible for determining flower color in chickpeas. Give your answer by assigning genotypes, phenotypes and ratios. B. Explain these results if two genes are responsible for determining flower color in chickpeas. Give your answer by assigning genotypes, phenotypes and ratios. C. How would you test which hypothesis (one gene or two genes) is the most likely hypothesis
Answer and Explanation:
a. The enes are responsible for expressing the characteristics of an individual. However, genes responsible for the same trait have different alleles, which make these traits different from each other, as is the case with chickpea flowers. Alleles can be h0m0zygous dominant (AA), recessive h0m0zygous (aa) or heterozygous (Aa), in short, dominant alleles are expressed in capital letters and are always expressed by the organism, so the alleles with greater proportions within an intersection, since they can be expressed in h0m0zygous and heterozygosis. Recessive alleles, however, can only be expressed in h0m0zygous and therefore have a smaller proportion.
B. Chickpeas have a type of dominance called incomplete dominance. This type of dominance occurs when the dominant alleles (AA) do not suppress the expression of the recessive genotype (aa), but joins the one showing an intermediate phenotype to the phenotype of the two alleles. This recessive phenotype can be seen in the heterozygous allele (Aa). Thus, we can see that the dominant flowers have AA alleles and have a white phenotype, while recessive flowers have aa alleles and have a blue phenotype, as explained in the question above. The crossing between these two plants generates an offspring where all the flowers present the pink phenotype, which is the intermediate phenotype between blue and white, in addition, this crossing generated an offspring that presents the Aa phenotype. You can also see this variety of colors at the crossing of the F2 generation, where most plants have the intermediate phenotype (Aa), followed by the dominant phenotype (AA) and followed by the recessive phenotype (aa). All crossings can be seen in attachments.
c. To test the hypothesis of one or more genes responsible for these characteristics, we would have to do biochemical and molecular tests. For that, it would be necessary to make a DNA extraction from the plant, PCR reactions and the isolation of one or more genes related to the color of the flowers.

As a part of the nitrogen cycle, fish contribute nitrogen to their environment by doing which of the following?
Producing waste
Eating plants
Drinking water
Breathing air
Fish contribute nitrogen to their environment by eating plants, the nitrogen cycle in a pond starts and ends with the fish, hence option B is correct.
How are different organisms involved during the nitrogen cycle?Fish produce waste after eating either plants or fish food. It's ammonia in this garbage. An organism's decomposition is another source of ammonia.
Ammonia is converted into nitrite in the first step. Food and waste that enters the tank and decompose emit ammonia, also known as hydrogen nitride, into the system.
Fish and corals are extremely poisonous to ammonia. All living things just take in these molecules through eating and use them in their own bodies.
Therefore, animals that pass away also add to the nitrogen cycle. Decomposed nitrogen-rich chemicals from animal corpses are returned to the soil for recycling and reusing.
