how do populations and communities affect one another?
Answer:
How can a change in one population affect the entire community in an ecosystem? If one population dies out, all the populations that depend on that species for food may also die out. A change in one population affects the entire community because all the populations of a community depend on each other.

What enzyme glues the nucleotides
together along the sugar-phosphate
backbone?
Answer:
The bases bind to one other via hydrogen bonding to secure the nucleotide to the template strand. The protein DNA ligase then fuses the sugar-phosphate groups of adjacent nucleotides to create the DNA backbone. These bonds are known as phosphodiester bonds.

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.

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.

Which statement about infiltration is TRUE? 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.

What conclusion about the effect of copper on plants is best supported by the information in the advertisement?
A.
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.

1. If the ecosystem is balanced, which populations should be the largest? Which should be the smallest?
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

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).
Therefore when you cross SS with ss the genotypes obtained are Ss, Ss, Ss and Ss.

What are cellular organisms?Cellular organisms are living beings that consist of one or more cells. Cells are the basic unit of life and the building blocks of all living organisms. Cellular organisms include all living things from bacteria to complex multicellular organisms such as plants and animals.
Cells have a variety of structures and functions depending on the type of organism they belong to. In unicellular organisms, such as bacteria, a single cell performs all the functions required for life. In multicellular organisms, cells are specialized to perform different functions, such as carrying oxygen in red blood cells or detecting light in the retina of the eye.
Cellular organisms have the ability to reproduce, grow, and respond to their environment. The study of cellular organisms is fundamental to the fields of biology, medicine, and biotechnology.
