Answer:
1) Create a hypothisis 2) Create experiment 3) collect data 4) write conclusion
The four steps that a scientist uses to solve a problem are creating hypothesis, experiment, data sorting and writing conclusion.
What are hypothesis?A hypothesis is an elaboration posited for a characteristic. The scientific technique requires that a hypothesis be testable in order for it to be considered a scientific hypothesis.
Scientists typically base scientific hypotheses on previous findings that cannot be adequately explained by existing scientific theories.
Any process that co-ordinate system data into some defined order to make it simpler to understand, analyze, or visualize is referred to as data sorting.
The conclusion is the final section of an academic essay. The conclusion should restate your response to the question and briefly summarize key points. It does not contain any new points or information.
A scientist solves a problem by developing a hypothesis, conducting an experiment, sorting data, and writing a conclusion.
Thus, by using these steps, scientist can come to an end for the problem.

5. The lion researchers in the film have studied 20% of the park and identified 41 lions. (Show your
work/justify your answer for each section.)
a. The entire Gorongosa park is 4,000 km². Approximately how large (in km) is the portion of
the park that has been studied?
ASAP PLSS
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].
What do you mean by the researcher?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].

Zara had a birthday and was able to choose a pet. The pet that she chose was a beautiful clownfish named Bozo, a common salt water fish. Zara already has a tank with goldfish at home. Use your knowledge of diffusion & osmosis to tell Zara how to take care of Bozo.
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.

Which atom is involved in giving your heart energy to beat?
O carbon
O gold
O oxygen
O iron
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.
Please also describe how actin-binding sites are made available for cross-bridging with myosin heads during contraction.
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.

What causes ocean tides to reach higher up on a shore at certain times of day than at others? A. The moon's gravity and Earth's rotation B. The ocean's conveyor belt and refraction C. Earthquakes and volcanoes O D. Temperature and salinity differences
Answer:
A
Explanation:
I read about ocean tides. the Moon has an effect on the ocean which causes the ocean to bulge toward the Moon. When the Moon is in alignment with the sun the ocean bulges out more because of the added gravity. The Moon though smaller than the sun has more gravitational pull than the sun.

1.How does Nitrogen cycle through the enviroment?
2. Trace the steps that carbon cycles from plants,animal,and enviorment?
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.

Plan a controlled experiment that uses the simulation to investigate how changing the mass of an object changes its acceleration. The net force on the object must stay the same. Record your plan here.
It is possible to measure how acceleration changes with mass by throwing objects with different mass from the same height and measuring the acceleration.
What are the important factors for the experiment?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.

- the amount of iron in blood depends on the amount of red meat a person eats.
Answer:
The answer is:
Independent: red meat eaten by a person
Dependent: iron in the blood
Explanation:
A dependent variable has to depend on something else, so in order for a dependent variable to exist or happen, there has to be the independent variable. The independent variable is something that does not need anything else to happen for it to take place. It s independent. Such as, a mother cannot have a child without sperm. The mother have a child is dependent, where the sperm is independent.

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.
What is a microscope?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.

if you are at a 60X magnification and the field diameter is 3.2mm an object that's about 1/4th the size of the field diameter what is the size of the object?
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.
