In which sealed container would the organisms be able to continuously cycle
O2 and CO2 gases?
A. A terrarium with a plant and a snail
B. An aquarium with fish and plastic plants
C. A terrarium with tadpoles and a pool of water
D. An aquarium with rocks and snails
Answer:Option A
Explanation: The snail breaths in the O2 which will then exhale CO2, therefore the plant will take that and process the CO2 back into O2.
The organisms would be able to continuously cycle O2 and CO2 gases in a sealed container of a terrarium with a plant and a snail. Thus, the correct option is A.
How do O2 and CO2 cycle in the environment?The carbon dioxide is utilized by the photosynthetic plants in order to synthesize their own food through the process of photosynthesis. They form oxygen as a product which is then utilized by other living organisms for respiration and exhaling carbon dioxide in the surroundings.
A terrarium with a plant and a snail follows the same principle of exchanging oxygen and carbon exchange within the sealed container environment which is described above.
An aquarium with fish and plastic plants does not exchange carbon dioxide and oxygen because plastic plants are not able to perform photosynthesis.
Therefore, the organisms would be able to continuously cycle O2 and CO2 gases in a sealed container of a terrarium with a plant and a snail. Thus, the correct option is A.

write a paragraph with 10+ sentences about the peridodic table. also write another paragraph with 10+ sentences about density
Answer:
Periodic table:
The periodic table is a chart that arranges the chemical elements in a useful, logical manner. Elements are listed in order of increasing atomic number, lined up so elements that exhibit similar properties are arranged in the same row or column as others.
Although Dmitri Mendeleev is most often cited as the inventor of the modern periodic table, his table was just the first to gain scientific credibility. It wasn't the first table that organized the elements according to periodic properties.
There are about 94 elements on the periodic table that occur in nature. All of the other elements are strictly human-made. Some sources state more elements occur naturally because heavy elements may transition between elements as they undergo radioactive decay.
Technetium was the first element to be made artificially. It is the lightest element that has only radioactive isotopes (none are stable).
The International Union of Pure Applied Chemistry, IUPAC, revises the periodic table as new data becomes available. At the time of this writing, the most recent version of the periodic table was approved in December 2018.
The rows of the periodic table are called periods. An element's period number is the highest unexcited energy level for an electron of that element.
Columns of elements help to distinguish groups in the periodic table. Elements within a group share several common properties and often have the same outer electron arrangement.
Most of the elements on the periodic table are metals. The alkali metals, alkaline earth, basic metals, transition metals, lanthanides, and actinides all are groups of metals.
The present periodic table has room for 118 elements. Elements aren't discovered or created in order of atomic number. Scientists are working on creating and verifying elements 119 and 120, which will change the appearance of the table, though they were working on element 120 before element 119. Most likely, element 119 will be positioned directly below francium and element 120 directly below radium. Chemists may create much heavier elements that may be more stable because of the special properties of certain combinations of proton and neutron numbers.
Although you might expect atoms of an element to get larger as their atomic number increases, this does not always occur because the size of an atom is determined by the diameter of its electron shell. In fact, element atoms usually decrease in size as you move from left to right across a row.
The main difference between the modern periodic table and Mendeleev's periodic table is that Mendeleev's table arranged the elements in order of increasing atomic weight, while the modern table orders the elements by increasing atomic number. For the most part, the order of the elements is the same between both tables, though there are exceptions.
Destiny:
That is, density (p) is equal to the total mass (M) divided by total volume (v). This formula can be used to determine the density of any substance. Common units for the measurement of density include grams (g), milliliters (ml), or grams per cubic centimeter. For instance, if there are 50 grams of a given substance within a cubic centimeter, that unit’s density is 50g/mm3.
Density can vary according to temperature and pressure. Applying pressure to an object decreases volume, which then increases density. Increasing the temperature of an object almost always decreases its density by increasing its volume.
By heating the bottom of a volume, especially a fluid volume such as a liquid or gas, convection causes the substance to rise, thus increasing the volume. The temperature variation is typically minor in solids and most liquids, but much greater in gases. The abbreviations to know are:
NTP: Normal Temperature and Pressure. Equal to 20 degrees C (68 F) and 1 atmosphere of pressure. Our examples below are all at NTP.
STP: Standard Temperature and Pressure. Equal to 0 degrees C (32 F) and 1 atmosphere of pressure.
These standardized pressures and temperatures make it possible to confirm equal densities are being used regardless of the application.

1. In cattle (R) is incompletely dominant over white (W) hides. Roan is the name of the color that results from the incomplete dominance. What are the
possible results if a white male is crossed with a roan female? Make sure to give genotypic AND phenotypic ratios in your answer.
When white male (WW) is crossed with a roan female (RW), 2 roan (RW, RW): 2 white (WW, WW) offspring are produced.
What is genotype?"The internal makeup of genes is called genotype."The alternative form of gene is called allele.The allele that is expressed in the generation is called dominant allele and the allele whose expression is masked and is only expressed if both of its copy is present is called recessive allele.What is phenotype?"The expressed characters are called phenotype."What is incomplete dominance?"In this condition both alleles of a gene are expressed, which will result in an intermediate or different phenotype."Here, it is given that red (R) is incompletely dominant over white (W) hides, which means that when RR is crossed with WW it produces RW (roan color). So, when RW (roan color) is crossed with WW (white color) it produces RW, RW, WW and WW.Hence, 2 roan (RW, RW) : 2 white (WW, WW) offspring are produced.

From the moth’s point of view, is the ability to be seen an advantage (known as an advantageous trait) or disadvantage (known as a disadvantageous trait)? Explain your reasoning.
Answer:
Disadvantageeous trait
Explanation
Since the moth is not high up in the food chain, it would want to hide from others by blending in with its surroundings rather than be easily seen as that would just make it easier for them to become easy prey for anything higher up in the food chain nearby.
