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:

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.

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:

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.

Explanation:

Hoped I helped you out please mark me brainliest!!!

With the creation of the microscope, humans were able to observe plant and animal cells, and as technology advanced, scientists were able to learn more about these various types of cells.

A microscope is a device that can be used to examine small objects, including cells. The image of an object is magnified in the microscope by at least one lens.

In most cases, the light is focused on the sample by passing it through a condenser.

After passing through the sample, the light passes through the objective lens, which magnifies the image of the sample, and then to the oculars, where the enlarged image is viewed.

The discovery of the green fluorescent protein (GFP), the development of increasingly sophisticated microscopes, and the development of in vitro assays that faithfully reproduce cellular functions are just a few examples of technological advances that have fueled many areas of cell biology.

Thus, it can be concluded that the advancements in technology help scientists better understand process of cell division.

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.

Answer:

See the answer below

Explanation:

The advice I would give  to Zara would be that she should keep Bozo in a separate tank with common salt water away from the goldfish. Bozo is a salt water fish while the goldfish can only survive in freshwater.

If Bozo is kept in a saltless water/freshwater tank with the goldfish, the water would be hypotonic to Bozo. Consequently, water will osmotically diffuse into the cells of Bozo, the cells would become turgid and lyse, and this would lead to the death of the fish.

If the goldfish is kept in the same salt water tank with Bozo, the salt water would be hypertonic to the goldfish. Consequently, water will osmotically diffuse out of the cells of the goldfish into the surrounding salt water, the cells of the goldfish would become flaccid, and this would lead to the death of the fish.

Answer:

I don't know the answer

Explanation:

is is this even a question cos I don't think so.

Answer: The calcium ion binds to troponin, and this slides the tropomyosin rods away from the binding sites.

Explanation:

Contraction and relaxation of muscle cells brings about movements of the body. The contractile myofilament called sarcomeres are bounded at each end by a dense stripe called the Z - line, to which the myosin fibres are attached, and lying in the middle of the sarcomere are the actin filaments, overlapping with the myosin.

When action potential spreads from the nerve along the sarcolemma (muscle cell membrane), it penetrates deep into the muscle cell through the sarcoplasm (cytoplasm of muscle cell), and releases CALCIUM from the intracellular stores.CALCIUM triggers the binding of myosin to the actin filament next to it forming CROSS BRIDGES.

For this to occur, ACTIN BINDING SITE has to be made available. TROPOMYOSIN is a protein that winds around the chains of the actin filament and covers the myosin-binding sites to prevent actin from binding to myosin. The first step in the process of contraction is for calcium ions to bind to troponin so that tropomyosin can slide away from the binding sites on the actin strands.
