Raul wants to study how pot size affects the growth of plants. To do this, he intends to purchase three different pots of varying diameter. Then, he will fill each pot with the same amount of soil and plant different kinds of flowers in each pot. Finally, he will place the pots side by side in a sunny location and water each pot daily with the same amount of water.
Answer:
No
Explanation:
Based on the exact methodology that Raul is using he will never produce valid results. This is mainly due to the fact that there are too many changing variables in his experiment. In order to produce valid results, the experiment can only have one changing variable (independent variable) at a time, while all of the other variables need to be controlled/constant. This would allow Raul to isolate which change is actually causing the desired effect in the plants. The way that Raul has his experiment set-up he will not be able to pinpoint exactly what variable or aspect is actually causing the growth of the plants.
State the relationship between particle size and porosity
helppp
Answer:
The shape and size of the particles affect the way that they pack together in a certain amount of space, which affects a rock's porosity. ... But rocks change over time. When enough pressure, or force, is put on a rock, the pressure can make the rock pack its particles closer together.
Explanation:
I looked it up on google.
Answer:
the larger the particles the harder it is to pack the atoms together, however with the help from exterior forces they can be forced together.

Explanation:
Crossing over occurs when (4 points)
Answer:
Crossing over is the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis, which results in new allelic combinations in the daughter cells.
When chromosomal homologs communicate with one another during Meiosis I's metaphase, crossing over takes place.
What is Crossing over?When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place.
Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up. The same genes may be present on the two chromosomes in different versions.
The exchange of genetic material between non-sister chromatids of homologous chromosomes occurs during crossing over, an enzyme-mediated process. It happens during meiotic prophase I's pachytene stage.
Crossing over occurs during Meiosis I's metaphase when chromosomal homologs interact with one another.
Thus, this way, crossing over takes place during meiosis.

Most S-waves from an earthquake disappear at a distance of about 11,500 kilometers from the epicenter of the earthquake. Explain why this occurs in terms of structure of Earth's interion.
Answer:
When an earthquake occurs the seismic waves (P and S waves) spread out in all directions through the Earth's interior. Seismic stations located at increasing distances from the earthquake epicenter will record seismic waves that have traveled through increasing depths in the Earth.
Seismic velocities depend on the material properties such as composition, mineral phase and packing structure, temperature, and pressure of the media through which seismic waves pass. Seismic waves travel more quickly through denser materials and therefore generally travel more quickly with depth. Anomalously hot areas slow down seismic waves. Seismic waves move more slowly through a liquid than a solid. Molten areas within the Earth slow down P waves and stop S waves because their shearing motion cannot be transmitted through a liquid. Partially molten areas may slow down the P waves and attenuate or weaken S waves.
When seismic waves pass between geologic layers with contrasting seismic velocities (when any wave passes through media with distinctly differing velocities) reflections, refraction (bending), and the production of new wave phases (e.g., an S wave produced from a P wave) often result. Sudden jumps in seismic velocities across a boundary are known as seismic discontinuities.
Within the Earth, molten areas slow down P-waves and stop S-waves because shearing motion of the waves cannot be transmitted through a liquid.
Earthquake cause the seismic waves (P and S waves) that spread out in all directions even in the Earth's interior. Seismic waves move more slowly through a liquid than a solid.
Within the Earth, molten areas slow down P-waves and stop S-waves because shearing motion of the waves cannot be transmitted through a liquid.
Therefore, most of the S-waves of an earthquake disappear about a distance of 11,500 km from the epicenter.

Tay Sachs is a disease caused by a mutation in a gene that codes for an enzyme used to break down complex molecules. Patients that have Tay Sachs accumulate excessive fat in brain cells and nerve cells. Normal functioning of this cell structure results in the digestion and removal of harmful fat accumulations, old cell parts, and invaders. Due to a mutation, the enzyme needed to remove fat accumulations does not function. Based on this information, what cellular structure is not functioning properly?
Answer:
Based on the given information , the cellular structure , which don not function properly in Tay Sachs disease is Lysosomes
Explanation:
LYSOSOMES -: In many animal cells, a lysosome is a membrane-bound organelle. These are spherical vesicles containing hydrolytic enzymes that can break down many types of biomolecules. A lysosome, with both its membrane proteins and its lumenal proteins, has a particular composition. There are a number of enzymes in lysosomes, helping the cell to break down different biomolecules that it swallows, including peptides, nucleic acids, carbohydrates , and lipids (lysosomal lipase). For optimal function, the enzymes responsible for this hydrolysis need an acidic environment.
TAY SACHS DISEASE -: The autosomal recessive disorder Tay-Sachs is caused by mutations in both gene alleles (HEXA) on chromosome 15. HEXA codes for the enzyme β-hexosaminidase A alpha subunit. This enzyme is contained in organelles, lysosomes, which break down large molecules for the cell to recycle.
Normally, β-hexosaminidase A helps to degrade a lipid called ganglioside GM2, but the enzyme is absent or present only in very small amounts in Tay-Sachs individuals, enabling excessive accumulation of ganglioside GM2 in neurons. In the different types of Tay-Sachs, the progressive neurodegeneration seen depends on the speed and degree of accumulation of GM2 ganglioside, which in turn depends on the amount of functional β-hexosaminidase A present in the body.
Hence , the answer is lysosomes .

Explanation:
Why the tropical forest has a more lush plant life than the tundra in regards to how fast things decompose.
Answer:
Because of Nitrogen
Explanation:
Nitrogen seems to be much difficult for plants to acquire because they can only consume nitrogen when it is combined with oxygen or hydrogen, which is why tropical forests have a lusher plant growth than tundra.The decomposition process is the secret to maintaining the nitrogen cycle going since the bulk of fixed nitrogen arrives from decaying organisms and faces being broken down by bacteria.Animal cells and plant cells both contain cell membranes that surround the outside of the cell. Plant cells have an additional outside layer, the cell wall.Select the statement(s) below that explain(s) why plants have the additional outer layer protection.Select ALL that apply.

How can an abiotic factor like temperature impact the population size of an ecosystem
Answer/Explanation:
Abiotic factors are non-living factors such as temperature, light, water, humidity, acidity, etc.
They strongly impact the ability of organisms to grow and successfully reproduce, and therefore affect the diversity of organisms in any given area.
If the temperature, light, and water availability (for example) are optimal, then species of plants will be able to grow successfully. This increases their populatuion size. Not only that, but it also provides a greater food supply for the animals that eat the plants, so their population will also grow.
