Question:
As part of an experiment, Riley planted six plants in regular potting soil. Six other plants were planted in potting soil with coffee grounds. The plants with the coffee grounds are the________ group. The plants with just potting soil are the________ group.
Answer:
As part of an experiment, Riley planted six plants in regular potting soil. Six other plants were planted in potting soil with coffee grounds. The plants with the coffee grounds are the__experimental__ group. The plants with just potting soil are the__control_ group.
Explanation:
During an experiment, data from an experimental group is compared with the data from a control group. Both groups are selected from the same pool or population, so they are identical in all aspects except for the independent variables.
The control group is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment.
The experimental group is the one that receives the experimental procedure or treatment. The researcher voluntarily changes the independent variables in the experimental group to observe how they affect the group under study. These variables are kept constant in the control group, not influencing the results, while the experimental group receives the treatment. There can be several experimental groups.
In the exposed example, the coffee in the soil is acting as the treatment. And the regular soil is the unchanged environment.
Plants that grow in soil with coffee are the experimental group because the researcher wants to know how the coffee affects the plants´ growth.
Plants growing the regular soil are the control group because they are not affected by the coffee. If there is any other factor influencing the results in the regular soil, it will be revealed by these plants.
In an experiment, data from the experimental group is compared with the data from the control group.
The given blanks for the statement can be given as:
As part of an experiment, Riley planted six plants in regular potting soil. Six other plants were planted in potting soil with coffee grounds. The plants with the coffee grounds are the experimental group. The plants with just potting soil are the control group.
The experiment involves an experiment and a control group. The value from the experimental group is measured with the values obtained from the control group.
The data in both groups are selected from a similar gene pool or population.
The control group in an experiment helps in the identification of the factors influencing the probable results.
The experimental group is the one that undergoes the experimental procedure or treatment. The independent variables are voluntarily changed and the researcher observed the effects of variables in the experimental group.
The variables in the control group are constant and do not affect the results, whereas in the experimental group the variables are changed and affect the results.
For example, the coffee in the soil is a type of treatment, in which the regular soil is the unchanged environment.
Plants will grow in the environment where the coffee has been incorporated, and the researcher wants to study the impact of coffee on the growth of the plant.
Plants in the regular soil will not be affected by the coffee and are the control group. The factor influencing the results in regular soil will be expressed in the plant.

¿Cómo defines a una Célula Haploide?
Answer:
La mitad de cromosomas.
Explicación:
Las células haploides se refieren a aquellas células que tienen la mitad de cromosomas. Estas células haploides se forman debido a la división celular de la meiosis. En la división celular de la meiosis, una célula madre se divide en cuatro células hijas que tienen la mitad de cromosomas. Estas células haploides están presentes en los espermatozoides de los gametos masculinos y femeninos, que se fusionaron formando células diploides que tienen el doble de cromosomas. El cigoto formado debido a la fusión de espermatozoides y óvulos son de naturaleza diploide.
What is NOT a function of the
nucleus?
A. Directs protein synthesis
B. Houses DNA
C. Functions as the powerhouse of the cell
Answer:
function as the powerhouse of cell
Explanation:
we have read the power house of cell as a mitochondria
==========================================================
Explanation:
The mitochondria is responsible for generating the cell's energy, hence the phrasing "the mitochondria is the powerhouse of the cell".
The nucleus holds the DNA, so we can rule out choice B. The DNA in turn is connected to forming the proteins. The actual protein synthesis happens in the ribosomes, but the DNA is used as a blueprint (more or less) to assemble the correct amino acids in the correct order to form the complicated protein chains. In short, the nucleus indirectly helps direct the protein synthesis, so we can rule out choice A.

Answer:
Osmosis is a process in which molecules pass from semipermeable membrane.
Explanation:
Osmosis is a biological process. The solvent molecules pass through semipermeable membrane and then solute particles move through the membrane with the help of water. These molecules are not capable of passing through the membrane in absence of water.

E.
watching a movie
Answer:
C. running a marathon
Explanation:
When you run a marathon you eventually switch to anaerobic respiration since not enough oxygen is present for aerobic respiration to occur (which uses oxygen as the last electron carrier in the electron transport chain). This process causes lactic acid to be produced.
Answer:
running a marathon

Which of the following is not one of the seven primary odors humans recognize?
fresh
putrid
pungent
roses
Answer:
roses
Explanation:
It occurs when an odor binds to a receptor within the nasal cavity, transmitting a signal through the olfactory system.2 Glomeruli aggregate signals from these receptors and transmit them to the olfactory bulb, where the sensory input will start to interact with parts of the brain responsible for smell identification, memory, and emotion.3
There are many different causes for alteration, lack, or disturbance to a normal sense of smell, and can include damage to the nose or smell receptors, or central problems affecting the brain. Some causes include upper respiratory infections, traumatic brain injury, and neurodegenerative disease.
Answer:
Fresh
Explanation:
When you look at the chartr, Roses were cconsidered a floral scent, which was listed, then there was putrid, pungent, and 3 others, the only one that wasn't listed was fresh, because often out scent and taste work together to help us find rotten foods, but we find that by smelling putrid scents or pungent scents, rather than fresh scents. Therefor the correct response is fresh

Describe what a sustainable ecosystem looks like with a real-life example
Answer:
The Appalachian Region in the southwestern United States, which is one of the most richly biodiverse regions in the world. Overall, cities that recycle & reuse basically exist in harmony with the surrounding environments are also considered sustainable ecosystems. A sustainable ecosystem is one where even when things are taken, nature still has enough to function and the ecosystem/area is healthy. But dealing with domestic, industrial, & agricultural waste is a growing environmental issue. That is NOT a sustainable ecosystem.

How is cytokinesis different
in plants and animals
Answer:
MAIN DIFFERENCES
- During cytokinesis, animal cells undergo a narrowing in the center, which does not occur in plant cells.
- Once the process is finished, the plant cells are partially united while in the case of animals they remain separated.
- A fundamental difference is that in animals, cytogenesis occurs by strangulation, but this is not the case of plants, which is by septation.
Explanation:
Forces occur in action-reaction pairs.
A. 1st Law
B. 2nd Law
C. 3rd Law
Answer: C (3rd law)
Explanation:
Newton's third law of motion states that every action has an equal and opposite reaction. This means that forces always act in pairs. Action and reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don't cancel out.
