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].

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.

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.
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.
**anatomy & physiology question**
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.
The Drosophila genes for white eyes (w), cut wings (ct), and tan body (t) lie at map positions 2.00, 15.0, and 21.0, respectively. Of 1000 progeny, 7 are double crossovers. What is the degree of interference
Answer:
The coefficient of interference, I, is 0.1 (10% expressed as a percent)
Explanation:
Available data:
genes for white eyes (w), cut wings (ct), and tan body (t) lie at map positions 2.00, 15.0, and 21.0, respectivelyOf 1000 progeny, 7 are double crossovers.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:
observed double recombinant frequency=total number of observed double recombinant individuals/total number of individuals expected double recombinant frequency: recombination frequency in region I x recombination frequency in region II.By knowing the positions of genes, we can estimate the distances in MU between them per region.
The distance between w and ct genes is 15 - 2 = 13 MUThe distance between ct and t genes is 21 - 15 = 6 MUNow that we know the distances, we can estimate the recombination frequencies by dividing each distance by 100.
recombination frequency of w-ct region = 13MU / 100 = 0.13recombination frequency of ct-t region = 6MU / 100 = 0.06Now 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)

FIND THE INDEPENDENT & DEPENDENT VARIABLE!
- 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.
In which experimental set up shown would you expect the Elodia plant inside a test tube to produce the least amount of oxygen
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 adaptation?In biology, adaptation has three related meanings. It is the dynamic evolutionary process of natural selection that fits organisms to their environment, enhancing their evolutionary fitness. Secondly, it is a state reached by the population during that process.
The ability of living organisms to adjust themselves to their surroundings is called adaptation. Adaptations are the changes in structure or behaviour of an organism that will allow the organism to survive in that habitat.
Adaptations are unique characteristics that allow animals to survive in their environment. There are three types of adaptations: structural, physiological, and behavioral.

Feeding problems may develop during the preschool years partially because of:_______
a. decreased appetite associated with decreased growth rate.
b. increased appetite associated with increased growth rate.
c. increased metabolic rate.
d. increased need for finger foods.
Answer:
The correct option is A.
decreased appetite associated with decreased growth rate
Explanation:
Feeding problems may develop in preschool age because of decreased appetite associated with decreased growth rate and this is because at the preschool age, there is no rapid growth, the growth rate is reduced which is as a result of decreased appetite for food. We all know that food supply the body with energy and necessary nutrients for growth. When there is decreased appetite enough food needed for growth will not be consumed , hence decrease growth rate.

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.
