Which statement is NOT true of soils?
Weathered parent material makes up most of the B-horizon.
All of Earth's systems are represented in a soil.
The C-horizon of a soil can contain unweathered rocks.
Organic matter gives the A-horizon in a soil a dark color.
Answer:
b
Explanation:
The statement that is NOT true of soils is: "All of Earth's systems are represented in a soil."
How much soil is important on earth ?Soil is a critical resource on Earth, as it is essential for supporting plant growth and providing a habitat for a wide variety of organisms.
While soils are complex and dynamic systems that interact with many other Earth systems, not all Earth systems are represented in a soil. For example, soils do not directly represent the atmosphere or the hydrosphere, although they interact with both of these systems in important ways.
The other three statements are true of soils:
Weathered parent material makes up most of the B-horizon: The B-horizon is typically composed of weathered rock and mineral fragments that have been transported downward from the A-horizon.
The C-horizon of a soil can contain unweathered rocks: The C-horizon is the deepest layer of a soil and can contain unweathered bedrock or other geological material.
Organic matter gives the A-horizon in a soil a dark color: The A-horizon is the uppermost layer of a soil and is often darker than lower layers due to the presence of organic matter, which can give it a dark brown or black color.

Copper is absorbed and stored by the leaves, where it increases the rate at which pollen is produced.
B.
Copper is transported from the roots to the stem, where it slows the development of reproductive tissues.
C.
Copper is transported by the stem from the roots to the flowers, where it affects reproductive tissues.
D.
Copper is absorbed and stored by the roots, where it affects the development of eggs by the roots.
Answer:
D Copper is transported by the stem from the roots to the flowers, where it affects reproductive tissues.
Explanation:
Answer:
Copper is transported by the stem from the roots to the flowers, where it affects reproductive tissues.
Explanation:
i just had this question,
According to the advertisment, copper is essential for reproduction. So, it most likely affects a plant's reproductive structures, which are found within flowers. As Amazing Nutri-C is applied to the soil, the copper must be absorbed by the roots and then transported to these tissues by the stem of the plant.
Therefore, the conclusion that is best supported by the information in the advertisement is that copper is transported by the stem from the roots to the flowers, where it affects reproductive tissues.

What would happen if Cyclin proteins did not function properly in the cell cycle?
Cyclin proteins are important in cell cycle progression; they partner with cyclin-dependent kinase enzymes to allow the cell cycle to progress. Without them, cell cycle progression would be hindered/stopped.
The situation when the cyclin proteins should not be function properly in the cell cycle because it is arrested.
What is Cyclin degradation?It is the key step that governs exit from mitosis and it should be progress into the coming cell cycle. It is equally vital with respect to the progression that arise from the cell cycle. In this, the particular enzymes should be split down cyclines at the particular time with respect to the cell cycle.
At the time when there is decrease in the cyclin levels so the CDK should not be inactive. Also, the cell cycle should be arrest at the time when the cyclines fail to degrade.

What is a genotype?The whole complement of an organism's hereditary material is referred to as its genotype. An individual's alleles and variations that they carry in a specific gene or genetic region are also referred to as their genotype. Genotype is a term that may be used in both of these contexts.
The genetic make-up of an individual organism is referred to as its genotype. Your body's growth and development are guided by the information contained in your genotype, which acts like a set of instructions. When discussing the hereditary components of a certain characteristic, the term "genotype" is often used (like eye colour).

Answer:
Sugars move from “source” to “sink” ... Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar. The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks.

Group of answer choices groundwater is an unsafe (dangerous) source of water not meant for drinking Groundwater can remain in subsurface storage for long periods of time groundwater can NEVER return to the surface groundwater will ALWAYS discharge into a body of water
Answer: Groundwater can remain in subsurface storage for long periods of time.
Explanation:
The ground water is the water reservoir that gets accumulated beneath the earth crust due to the accumulation of water that seeps into the soil and rock due to the absorption by water bodies river, lakes, ponds, oceans, and rain or any kind of precipitation. The groundwater remains as a subsurface storage of water until the site of groundwater is searched and water is extracted from it for household, agricultural or industrial purposes.

The area of the cell that is associated with the production of ribosomes is the:
1. nucleolus
2. nucleus
3. nuclear pores
Answer:
Nucleolus
Explanation:
This is a more technical answer. The Nucleolus is located inside the nucleus and this is the location where the ribosomes are produced. They then leave through the nuclear pores to be sent out into the cell.
The area of the cell that is linked with production of ribosomes is nucleolus. The correct option is 1.
What is nucleolus?The nucleolus is a circular shape within the nucleus of cells that produces and assembles the cell's ribosomes. Ribosomal RNA genes are also transcribed in the nucleolus.
The nucleolus has the most visible realm in the nucleus of a eukaryotic cell, and its basic task is ribosomal RNA (rRNA) melding and ribosome biogenesis.
The nucleolus, as the site of ribosome biogenesis, is critical to cell metabolic activity.
It is made up of ribosomal DNA (rDNA), which is found in tandem arrays in nucleolus event coordinator regions.
The nucleolus synthesizes ribosomal subunits from proteins and ribosomal RNA, or rRNA.
It then starts sending the subunits to the rest of the cell, where they join together to form complete ribosomes.
Thus, the correct option is 1.

2. Why can the wolf be considered both a secondary consumer and a tertiary consumer?
3. If the original amount of energy found in the producer trophic level is 100 kcal how much is passed on to the primary consumer trophic level? How does this amount limit the number of members in the next higher level?
4. Analyze what would happen to this ecosystem if one of the primary consumers was removed from the ecosystem? What would happen if a new tertiary consumer such as a mountain lion came into the ecosystem? Describe how each level would be affected if each of these changes occurred.
Answer:
1. producers are the largest and consumers are the least
2. because wolves feed on both primary and secondary consumers
3. Only 10% of energy from each trophic level is passed on to the next; therefore, the energy passed to the primary consumer will be only 10 kcal.
4. disturbe,as we know that secondary consumers feed on primary consumers so if there is no primary consumers then all secondary consumers will die similarly all tertiary consumers will also die and life would be finish on the earth.
if a new tertiary consumer came into the ecosystem then it will create a problem as the number of primary and secondary consumer are same but the tertiary consumer are more so they will get less food and hence die

Why is DNA analysis useful for classification
Answer:
Well, it helps us categorize organisms so we can more easily communicate biological information.
Explanation:
do all organisms receive the same amount of energy? explain
Answer:
No, because energy is lost when lost if a plant does photosynthesis it consumes 10% of the energy produced by the sun a tertiary consumer will consume about 4% of that energy.
