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].

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.

Explanation:
Bees with short tongues are able to obtain nectar from deep flowers by drilling holes in the base of the flower without visiting the top of the flower. This behavior does not kill the flower. In a particular environment, bees with short tongues replace bees with long tongues. Predict the effect on the proportion of plants with deep flowers in future generations. Justify your prediction.
Answer:
The proportion of plants with deep flowers in future generations will decrease and will be very low.
Explanation:
To analyze this, we need to keep in mind the pollination process and the following general ideas:
Bees with long tongues can obtain nectar from deep flowers by visiting the top of them and extending their tongues to their bottom.During their visit to the flowers and their search for nectar, long-tongued bees transport pollen from flower to flower, favoring pollination.Bees with short tongues can obtain nectar from deep flowers by drilling holes in their base without visiting their tops.Short-tongued bees do not need to access the nectar by the top of the flower. They do not get in contact with stamens, so they do not play a pollinator roll. In a particular environment, bees with short tongues replace bees with long tongues.In this particular environment, long-tongued bees used to visit plants with deep flowers to get their nectar. They used to get in contact with mature stamens and carry the pollen on their bodies to the next flower. During this process, long-tongued bees were able to ensure pollination and helped to keep a high reproductive rate of plants with deep flowers.
When shorted-tongue bees arrived at this environment, they were able to replace long-tongued bees. They also looked for the nectar of deep flowers, but instead of visiting them from the top, they were adapted to obtain nectar by drilling holes in the flower base. In this way, they missed the contact with mature stamens and pollen.
Long-tongued bees disappear, and short-tongued bees did not play a role in the pollination process of deep flowers, then the reproductive rate of these vegetable species probably started to decline.
Probably, with time, the proportion of plants with deep flowers in an environment dominated by short-tongued bees will be very low.
The proportion of plants with deep flowers in future generations will decline if bees with short tongues replace bees with long tongues.
What do you mean by environment?Anything which is present in the surrounding of an organism is called its environment. It may consist of Biotic and abiotic factors.
Bees with short tongues are able to obtain nectar from deep flowers by drilling holes in the base of the flower without visiting the top of the flower. In this way, such bees are not in contact with mature stamen and pollen. Therefore, they will not play an effective role in pollination. And if such bees are replaced with long tongues bees, there will never be a deep flower obtained. Deep flowers are obtained by long-tongued bees because they take nectar from the top side and with it they also take mature stamen and pollen to perform successful pollination.
Therefore, the proportion of plants with deep flowers in future generations will decline, if bees with short tongues replace bees with long tongues.

A species of elm has winged-seeds. How would biologists explain how a species of elm with winged-seeds evolved from an ancestral elm species without winged-seeds
Answer:
In an ancestral elm species, mutations gave rise to the phenotypic trait "winged-seeds". Subsequently, selection favored elm plants with winged-seeds that diverged over time to become a separate species
Explanation:
A mutation is a genetic change in the DNA sequence. In general, mutations have a negative impact on the fitness of the individual (i.e., mutations are generally deleterious) and therefore they disappear from the population. However, there are situations where mutations are beneficial and confer an adaptive advantage, thereby increasing their frequency in the population. In this case, mutations associated with the formation of winged-seeds conferred an adaptive advantage (i.e., higher seed dispersal capacity) to individuals who had this phenotypic trait, thereby these individuals had more chances to reproduce and pass their genes to the next generation. Eventually, Elm plants with winged-seeds accumulated sufficient genetic differences to prevent interbreeding, leading to the formation of a separate species.

Describe the structure of the conjugated protein
haemoglobin, with reference to the levels of protein
structure.
Answer: Answer below, hope this helps! :D
Explanation:
A conjugated protein is a protein that functions in interaction with other (non-polypeptide) chemical groups attached by covalent bonding or weak interactions. ... The non-amino part of a conjugated protein is usually called its prosthetic group. Most prosthetic groups are formed from vitamins. Hemoglobin is a protein having a globular structure. Based on its structural properties, hemoglobin can be divided into two parts; a protein part and a heme group. The structure of the protein part can be studied at four levels; primary structure, secondary structure, tertiary structure, and quaternary structure.

What is the medical term for the process or procedure that destroys or inhibits disease-causing microorganisms to prevent infection:
Answer: Sterilization.
Explanation:
Sterilization is the process that kills, or deactivates all forms of life so then a product is considered free of viable microorganisms. This process must be designed, validated and carried out to ensure that it is capable of eliminating the microbial load of the product.
Since sterility cannot be demonstrated without causing the complete destruction of the products, sterility is considered when the probability of a product being contaminated is acceptably remote. A critical product is considered sterile when the probability of a microorganism being present in an active or latent form is equal to or less than 1 in 1,000,000 (sterility safety factor 10^-6).
Agents that kill microorganisms are called microbicides or more commonly called "germicides". If the agent kills bacteria, it is called a bactericide. And if it kills fungi, then it is called a fungicide. It is important to consider than after an exposure of the sterilized object to the air or its surroundings, it will have become contaminated again with microorganisms.
Examples of sterilization include physical methods and chemical methods. Physical methods include:
Wet heat (in steam autoclave) Dry heat (in sterilization oven) Radiation (gamma radiatio, electron beam, X-ray, ultraviolet, microwave, white light)Chemical methods include a variety of chemicals in liquid and vapor form, for example:
Hydrogen peroxideChlorine dioxideOzone gasesEthylene oxidePropylene oxidePeracetic acidHemophilia is a recessive sex-linked trait. A non-hemophiliac man and woman marry and

What is hemophilia?Hemophilia is a disorder which is rare which results when the blood does not clot in it's usual way as it does not have sufficient blood-clotting factors .A person suffering from hemophilia can bleed for a longer period of time resulting in blood loss.
It is almost always that hemophilia occurs genetically . Treatment of hemophilia include replacement of the specific blood clotting factor that is reduced. Symptoms of hemophilia vary from person to person depending on the level of the clotting factors.
Signs and symptoms include excessive bleeding ,large or deep bruises, pain or swelling in joints ,nosebleeds,etc.

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.
