Explanation:

sorry i can only tell you the first one

Introduction

What was the purpose of the experiment?

The purpose of this experiment is to create CO2, also known as carbon dioxide, and observe chemical reactions.

How can you identify the gas produced in a chemical reaction without observing the atoms and molecules directly? Explain.

If I look at how the gas would react or its qualities, I can identify the gas without having to observe its atoms directly.

Write a hypothesis based on observations and scientific principles.  

I hypothesize that the mixture produced carbon dioxide, an acidic and colorless gas. In addition to organic materials, such as leaves and dirt, carbon dioxide is also produced when they decay.

Experimental Methods

What tools or materials did you use to collect your data?

To conduct my experiment, I used a glass cup, baking soda, vinegar, paper to record my observations, and a match.

Data and Observations

Record your observations.  

The baking soda and vinegar made bubbles and some steam. When I put the match above the glass, the flame went out.

Conclusions

What conclusions can you draw about the identities of the gases produced in each chemical reaction? Write an evidence-based claim.

The chemical reaction of CO2 caused the flame to go out.

Based on your observations, which equation best models the reaction of vinegar (C2H4O2) and baking soda (NaHCO3)? Explain.

"C" _"2"  "H" _"4"  "O" _"2" +"NaHC" "O" _"3" →"Na" "C" _2 H_3 "O" _"2" + "H" _2 "O"+"C" "O" _2

"C" _"2"  "H" _"4"  "O" _"2" +"NaHC" "O" _"3" →"Na" "C" _2 H_3 "O" _"2" + "H" _2 "O"+"O" _2

"C" _"2"  "H" _"4"  "O" _"2" +"NaHC" "O" _"3" →"Na" "C" _2 H_3 "O" _"2" + "H" _2 "O"+"H" _2

"C" _"2"  "H" _"4"  "O" _"2" +2"NaHC" "O" _"3" →"Na" "C" _2 H_3 "O" _"2" + "H" _2 "O"+"C" "O" _2

The equation that best models the reaction of vinegar is A

Because "C" _"2"  "H" _"4"  "O" _"2"  is the acid vinegar

"NaHC" "O" _"3"   is the baking soda  

"Na" "C" _2 H_3 "O" _"2" + "H" _2 "O"+"C" "O" _2 is the product or the reaction.

Fulgurites, commonly known as "fossilized lightning", are natural tubes, clumps, or masses of sintered, vitrified, and/or fused soil, sand, rock, organic debris and other sediments that sometimes form when lightning discharges into ground.

Answer:

periapsis

Explanation:

Periapsis is the point when the orbiting object comes the closest to the thing it is orbiting around; for example, the moon is at periapsis when it is closest to the Earth.

Moon revolves around the earth in an elliptical pathway. At some point moon approaches earth at its closest point.  This point is called perigee. This closest approach is called periapsis.

Moon is the only satellite of earth. Moon revolves around earth along with rotating about its own axis. Earth have a gravitational pull into moon and this force will be different at different point of orbital revolution.

Moon's orbit is elliptical. The points of farthest approach to earth is called apogee  and the closest point is called perigee. Every planet will have an apogee and perigee with sun as for earth and also with their  satellites.

The farthest approach of moon from the earth is called apoapsis and the closest approach is called periapsis. Periapsis is also called perilunar, parselene, perilunar etc. Hence, option A is correct.

Quick getaway is the answer but I'm not too sure

Answer:

1. D (In population genetics, gene flow is the transfer of genetic material from one population to another.)

2. C (Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation. It can also cause initially rare alleles to become much more frequent and even fixed. When there are few copies of an allele, the effect of genetic drift is larger, and when there are many copies the effect is smaller.).

3. A  and also E (Individuals with inherited characteristics that allow them to best compete for limited resources will survive and have more offspring than those individuals with variations that are less able to compete. Because characteristics are inherited, these traits will be better represented in the next generation.)

4. D (Gene flow can increase fitness but if it happens in another environment, it decreases the adaptability. If alleles are advantageous, the offsprings' inheritance increases.

5. B (Mutations are the main source of alleles)

By stating that "Yellow butterflies breed during the summer season while red butterflies breed during the winter season" we are referencing a form of temporal isolation.

Temporal isolation is one of the limiting factors for sexual reproduction between closely related species. Temporal isolation refers to the situation in which two closely related species cannot interact sexually with one another due to the timing of their respective mating events.

The question states that the yellow butterflies will breed during the summer season, whilst the red butterflies breed during the winter. Normally, species like this are closely related enough to allow interspecies breeding to take place and create a new species or simply diversify the existing ones. However, due to the distinct timing of the breeding cycles for each butterfly, they will not be able to breed with one another, which is a prime example of temporal isolation.

Answer:

Answer below! : )

Explanation:

Explain 1) The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable. The dependent variable is the variable being tested and measured in an experiment, and is dependent on the independent variable. 2) Testing only one variable at a time lets you analyze the results of your experiment to see how much a single change affected the result. If you're testing two variables at a time, you won't be able to tell which variable was responsible for the result. 3) The control group and experimental group are compared against each other in an experiment. The only difference between the two groups is that the independent variable is changed in the experimental group. The independent variable is "controlled" or held constant in the control group 4) Not sure about this one sorry! 5) hypothesizing, observing, and experimenting. 6) This rule says that where you have one situation that leads to an effect, and another which does not, and the only difference is the presence of a single factor in the first situation, we can infer this factor as the cause of the effect. 7) No matter how carefully observations and experiments are performed, it cannot be ensured that every possible factor is the same in every observation. 8)  Munsell Charts are used to provide standard descriptions and names of color. 9) Nitrogen, phosphorus, and potassium. 10) Water table, also called groundwater table, is the upper level of an underground surface in which the soil or rocks are permanently saturated with water. 11) Humus significantly affects the bulk density of soil and contributes to its retention of moisture and nutrients. 12) Texture refers to the size of the particles that make up the soil. The terms sand, silt, and clay refer to the relative sizes of the soil particles. The combined portions of sand, silt, and clay in a soil determine its textural classification. 13) The main difference between sand silt and clay is their particle size. Sand particles are larger in size while clay particles are extremely fine, and silt particles are somewhere in between sand and clay particles. Sand, silt, and clay are the main mineral particles in the soil that affect its texture 14) Mineral matter is derived from the constituents of the parent material.  Organic matter.  The nature and abundance of iron.  Moisture content. 15) In some mineral soils aluminum can be dissolved at pH levels below 5.0 becoming toxic to plant growth. Soil pH may also affect the availability of plant nutrients. Nutrients are most available to plants in the optimum 5.5 to 7.0 range. 16) Phosphorus is essential for cell division and growth and promotes plant maturation. 17) Aspect of soil porosity concerns the oxygen found within these pore spaces. All plants need oxygen for respiration, so well-aerated soil is important for growing crops. 18) The ground above the water table may be wet to a certain degree, but it does not stay saturated. The dirt and rock in this unsaturated zone contain air and some water and support the vegetation on the Earth.

Answer: Photosynthesis, Decomposition, Respiration and Combustion

Explanation:

The cycling of carbon in the carbon cycle is released from animals and plants in form of carbon dioxide through respiration or released by decomposition and internalized by a process called photosynthesis in plants.

It initiates when a plant dies and gets buried turning into fossil fuel. This fossil fuel is burnt by humans converting most of the carbon into carbon dioxide.

Carbon dioxide is added to the atmosphere by respiration of animals and the plants. Plants again use this carbon dioxide to perform photosynthesis thus quickly adding it to their bodies from where the cycle continues.

Answer:

microtubules

Explanation:

Microtubules specific cytoskeletal element is most susceptible to mitotic inhibitors.

The third main component of the cytoskeleton, microtubules, are hard, hollow rods with a diameter of around 25 nm. Microtubules are dynamic structures that constantly assemble and disassemble within the cell, similar to actin filaments.

They have a role in a number of cell motions, including as some types of cell motility, the intracellular movement of organelles, and the division of the chromosomes during mitosis, in addition to determining the shape of the cell.

Microtubules, which typically consist of 13 linear protofilaments arranged around a hollow core, are created when tubulin dimers polymerize to generate them. The head-to-tail arrays of tubulin dimers that make up the protofilaments are organized in parallel.

Therefore, Microtubules specific cytoskeletal element is most susceptible to mitotic inhibitors.

The dichotomous key is a classification tool based on morphological characteristics. The correct option is B. Dichotomous keys can only be used to classify organisms based on their observable traits.

A dichotomous key might be considered a significantly useful tool to classify organisms.

The key provides an easy and fast way for identification by describing different morphological observable traits, leading you to the correct taxonomic classification.

The term dichotomous refers to how information is provided. You will always have two options (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism.

Each time you choose an option, it leads you to the following description, which gets more specific each time.

Probably you might need an atlas or a dictionary to understand some of the technical terminologies.

You will also need to carefully observe your specimen, to get to distinguish different traits. If the specimen is too small you might need a loup.

The correct statement is B. Dichotomous keys can only be used to classify organisms based on their observable traits.
