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:

0.8mm.

Explanation:

If the size of an object is about 1/4th the size of the field diameter so the size of an object is 0.8mm because the fourth part of field diameter is equals to 0.8mm. Due to knowing field diameter of microscope we can calculate the real size of objects that is too small which can't be seen with the naked eye. So one fourth part of field diameter is equal to 0.8mm.

What do you mean by arteries?

The arteries are the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body. Each artery is a muscular tube lined by smooth tissue and has three layers: The intima, the inner layer lined by a smooth tissue called endothelium.

What is oxygenated blood?

Oxygenated blood can be simply defined as a blood cell with large percentage of oxygen and low in carbon dioxide. It appears bright red in color and travels away from the heart to different parts of the body.

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:

The correct answer is - b. Air pollution from the excess fertilizers

Explanation:

In long term using excess amount of fertilizer than requirement will lead to several condition such a soil acidity, soil degradation, soil leacing, eutrophication of waterways and many but more improtant is green house gases and air pollution.

Using the excess amount of fertilizer does not help in increasing crop yield but gives negative impact. Using fertilizer more than requirement wil lead to release of toxic and harmful gases in atomosphere and fuming.

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.

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.

True

Explanation:

Answer:

800 km²

Explanation:

If the researchers have studied 20% of the 4000 km² park, to find out how much of the park in km they have studied, all you have to do is find 20% of 4000.

4000 x .20 = 800

800 km² is your answer.

If the area of the entire Gorongosa park is 4,000 km². Among which, 20% of the park is already studied, it means 800 [tex]km^2[/tex].

A researcher may be defined as a kind of person who significantly carries out academic or scientific research in order to find some unrevealed data and information.

According to the question,

The total area of Gorongosa park = Gorongosa park is 4,000 km²

The area which is already studied = 20%.

Now, you have to find the area that is already studied in km. So, you have to calculate the 20% of 4,000 km².

The area which is already studied = 4000 × .20 = 800 [tex]km^2[/tex].

Therefore, if the area of the entire Gorongosa park is 4,000 km². Among which, 20% of the park is already studied, it means 800 [tex]km^2[/tex].

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)

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.
