a student placed a stack of rocks on a ramp. she added clumps of soil rooted with live grass. using a garden hose, she then applied a steady spray of water that soaked into the soil, making it heavier. what does the students experiment model
Answers
Answer: its C
Explanation:
Since a steady spray of water soaked into the soil, making it heavier. This student's experiment models: C. The role of rainfall in mass wasting.
A rock can be defined as a solid naturally occurring landform and it is typically made up of various minerals.
In this experiment, a stack of rocks was placed on a ramp and clumps of soil rooted with live grass were added. By using a garden hose, the student then applied a steady spray of water which soaked into the soil and made it heavier in weight.
Hence, this experiment models the role rainfall (steady spray of water) plays in mass wasting.
Mass wasting is also referred to as mass movement or slope movement and it can be defined as a geomorphic process through which rock, debris, soil, and regolith are largely moved downward, especially due to the force of gravity.
Basically, mass wasting describes the downslope (downhill) movement of rock and soil due to a steep slope and force of gravity.
In conclusion, the steady spray of water acts as a force which moves some of the soil constituents downward, making it heavier.

A and B are biotic in nature, C, D, and E are abiotic in nature. In an open system, A produces D and E while B could not produce anything rather depend totally on the D and E produced by A. As the number of A increases, it favours the growth of B, the production of D and E also enhances the growth and development of B.
Answers
Answer:
A: Plants
B: Consumers
C: Sun
D: Oxygen
E: food
Explanation:
Abiotic factors refer to non-living things int he ecosystem, whereas the biotic factors are the living things in the environment.
A, in this case, is referring to the plants in the ecosystem, the producers. Plants produce D and E, that is, oxygen and food respectively. B are the consumers in the environment, the herbivores in particular that feed on the plants and rely on it as the only food source. C refers to the sun as the source of light energy for the plants.

How does the anaphase stage differ in the two phases of meiosis? A. Anaphase I separates sister chromatids and anaphase II separates homologous chromosomes into daughter cells. B. Anaphase I has homologous chromosomes attached to spindle fibres and anaphase II involves separation of these homologous chromosomes. C. Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.
Answers
Answer:
The answer is Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.
Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. So, in meiosis, there are two anaphases - the anaphase I in meiosis I and the anaphase II in meiosis II.
In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicate, which are present as pairs of sister chromatids. In anaphase of meiosis II, since the cell is haploid, there are 23 chromosomes in duplicate, which are present as sister chromatids.

When can exponential growth happen?
O A. When there is unlimited food and space
B. When the death rate is high
C. When carrying capacity is reached
D. When there is competition for resources
Answers
Answer: when there is Unlimited food and space
Explanation:
When there is unlimited food and space. Exponential growth occurs when a population has unlimited resources, such as food and space, and there are no limiting factors such as predation, disease, or competition for resources. In such a scenario, the population will continue to grow at an accelerating rate without reaching a carrying capacity. Hence option A is correct.
What is exponential growth?
Exponential growth can occur when there are no limiting factors that affect the population size. This means that the population has access to unlimited resources such as food, water, and space. In this scenario, the birth rate exceeds the death rate, and the population grows at an increasing rate over time.
As the population grows larger, the rate of growth also increases, resulting in a J-shaped curve on a graph.
However, in the real world, exponential growth is limited by factors such as predation, disease, competition for resources, and environmental factors like weather and natural disasters.
When these limiting factors are present, the growth rate of the population slows down, and the population may eventually reach a maximum size that the environment can support, known as the carrying capacity.
At this point, the population growth rate slows down to zero, and the population size stabilizes at or around the carrying capacity.
Hence option A is correct.

A student observed a dying plant in the corner of their science classroom. They learned the process of Photosynthesis and Cellular Respiration already in class. The students were trying to remember the correct chemical equation for the process. In order for the plant to be successfully creating its own food which chemical equation did the student write correctly?
Answers
Answer:
The general chemical equation for photosynthesis is
6CO2 +6 H20 → C6H1206 + 602,
Where CO2 is carbon dioxide, H20 is water, C6H12O6 is glucose, and O2 as oxygen a byproduct.
the process begins with the splitting of water molecules-Photolysis.
2H20 +2 NADP + 8 Photons → NADPH + 2H+2 O. Photons is sunlight that splits the water molecules.
Cellular respiration is the reverse of the process which is the
C6H1206 +6 O2 → 6H20 +6 CO2 +ATPs.
ATPs is the chief product, while C02 is the byproduct.

Answers
Answer:
A.
Explanation:
The cells control gene expression at transcription, translation, and the formation of the final protein.
What do you mean by gene expression?Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce end products, protein or non-coding RNA, and ultimately affect a phenotype, as the final effect.
Gene expression is the process by which the information encoded in a gene is turned into a function. This mostly occurs via the transcription of RNA molecules that code for proteins or non-coding RNA molecules that serve other functions.
Gene expression is a tightly regulated process that allows a cell to respond to its changing environment. It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made.
