Answer:

B.

Explanation:

It has a huge impact on the environment

It is being emitted in large amounts

And if we cut our carbon emissions in half it would delay the risk of raising the global temperature of 1.5 degrees Celsius but half of it would still pumped into the atmosphere along with the carbon dioxide already in the atmosphere.

But it is a greenhouse gas because it helps trap the heat remaining in Earth's atmosphere which is why the Earth is warming.

CO2 is a greenhouse gas.

what are greenhouse gases?

Greenhouse gases are gases in the atmosphere that affect the energy balance of the planet. The greenhouse effect is caused by them. Carbon dioxide (CO2), methane, and nitrous oxide, the most well-known greenhouse gases, can all be present in low concentrations in the environment.

The greenhouse gases in the atmosphere trap heat and warm the earth.

Carbon dioxide, methane, nitrous oxide, and water vapor (all of which exist naturally) are the principal greenhouse gases, as are fluorinated gases (which are synthetic).

Carbon dioxide (CO2) is released into the atmosphere as a result of the combustion of fossil fuels (coal, natural gas, and oil), solid waste, trees, and other biological materials, as well as chemical processes (e.g., manufacture of cement). As part of the biological carbon cycle, carbon dioxide is absorbed by plants and released from the atmosphere.

hence, CO2 is a greenhouse gas.

Answer:

Due to less concentration of carbondioxide gas.

Explanation:

Elodia plant inside a test tube produces the least amount of oxygen due to limited carbondioxide gas that is necessary for photosynthesis process. If a test tube has less amount of carbondioxide gas which is a reactant in photosynthesis so in the end the Elodia plant generates less amount of glucose as well as oxygen while on the other hand, if there is more carbondioxide gas is available to Elodia plant, more oxygen as well as glucose is produced.

Answer:

Synthetic rubber.

Explanation:

Polymerization can be defined as a type of chemical reaction in which molecules that are relatively small in size chemically combine to form a huge chain of molecules.

Simply stated, polymerization refers to a chemical reaction where two or more smaller molecules react to produce larger molecules of the same network or repetitive structural units.

In polymerization, the relatively small molecules are generally referred to as monomers while the larger molecules they produce are known as polymers.

Butanol was used in the production of synthetic (artificial) rubber through a fermentation process.

It is possible to measure how acceleration changes with mass by throwing objects with different mass from the same height and measuring the acceleration.

This experiment requires you to measure how acceleration changes if the mass changes. This implies you need to consider the following factors:

Acceleration: This factor is the one you will measure in your experiment.

Mass: This factor is the one you will need to control, this implies using objects from different masses and comparing if mas has any effect on acceleration.

Other: Net force, wind, etc. are other factors that need to be constant to prevent them affect the results.

Steps for the experiment:

Choose a specific heigh: One of the ways of measuring acceleration is to throw objects and determine the acceleration as they fall, so the first step will be to establish a height.

Throw different objects with different masses: You can begin with light objects and move into heavier objects.

Measure acceleration: Every time you throw an object, measure acceleration using the formula A = change in velocity/ time.

Answer: 1. The nitrogen cycle is a biogeochemical cycle.

2. The carbon cycle is a biogeochemical cycle.

Explanation:

1. The nitrogen cycle can be defined as the biogeochemical cycle in which the atmospheric nitrogen is utilized by the plants which is fixed by the soil bacteria. The nitrogen becomes the part of the biosphere as plants utilize it as an important development mineral. The nitrogen cycle involves the nitrogen fixation in which plants fix nitrogen by the help of bacteria into ammonia, nitrification in which the ammonia is converted into nitrite, nitrogen assimilation in which the plants assimilate and utilize the nitrogen for their growth and development, and denitrification involves the reduction of nitrite into atmospheric nitrogen. The conversion of nitrogen is carried out via physical and biological processes.

2. The carbon cycle involves the atmospheric carbon dioxide being circulated in plants as they utilize it for photosynthesis. The carbon dioxide is fixed by the plants in the form of carbohydrate which is consumed by the animals and on decomposition of plants and animals dead matter release carbon dioxide gas to the atmosphere. This allows the recycling of the carbon dioxide gas in the environment.

Answer:

It can significantly alter the homeostasis of the ecosystem

Explanation:

The trophic level is the position that occupies a given organism/ population/species in the food web. In a food web, the trophic levels are organized into a first category (formed by primary producers, e.g., plants), a second level (primary consumers, e.g., herbivores), and subsequent categories (predators, e.g., carnivores). The abrupt change in the number of organisms belonging to the same trophic level generally has a negative effect on the ecosystem by modifying the trophic structure of communities. For example, decreasing the number of producers will produce a decrease in the number of primary consumers, thereby altering the homeostasis (equilibrium) of the entire ecosystem. On some occasions, it may eventually lead to the extinction of populations and species.

Answer:

Oxygen

Explanation:

-How fast the heart beats depends on the body's need for oxygen-rich blood. At rest, the SA node causes your heart to beat about 50 to 100 times each minute. During activity or excitement, your body needs more oxygen-rich blood; the heart rate rises to well over 100 beats per minute.

-The heart, like any organ, requires blood for oxygen and other nutrients so it can do its work. The heart does not gather oxygen or nutrients from the blood flowing inside it. Instead, it receives blood from coronary arteries that eventually carry blood into the heart muscle.

Answer:

The coefficient of interference, I, is 0.1 (10% expressed as a percent)

Explanation:

Available data:

The coefficient of interference, I, is complementary with CC.

I = 1 - CC

To calculate the coefficient of coincidence, CC, we must use the next formula:

CC= observed double recombinant frequency/expected double recombinant frequency    

Note:  

By knowing the positions of genes, we can estimate the distances in MU between them per region.

Now that we know the distances, we can estimate the recombination frequencies by dividing each distance by 100.

Now that we know the recombination frequencies in each region, we can calculate the expected double recombinant frequency, EDRF, like this:

EDRF = recombination frequency in region I x recombination frequency in region II.

EDRF = 0.13 x 0.06 = 0.0078

Now, by knowing the total number of individuals in the progeny (1000) and the number of double crossovers (7), we can calculate the observed double recombinant frequency, ODRF:

ODRF = number of double crossovers / total number of individuals

ODRF = 7/1000 = 0.007

Finally, with the values of EDRF and ODRF, we can calculate the coefficient of coincidence, CC.

CC = ODRF/EDRF

CC =  0.007 / 0.0078

CC = 0.9

And by knowing the CC we can also get the coefficient of interference, I.

I = 1 - CC

I = 1 - 0.9

I = 0.1 = 10% (expressed as a percent)
