The three(3) potential challenges or important points to consider when conducting a data collection are described below.
Data collection is a detailed process that is used in gathering and measuring information from a selected source by a researcher.
To perform a data collection, the following important points are to be considered :
Cost of data: before data collection, a researcher should check if the data that is being considered is affordable. this is done to avoid quitting.Accuracy: there are different types of data collection techniques these include: questionnaires, interviews, focus groups, observation and case studies. the data collection technique that should be chosen should provide the most accurate results.Validity of data: if your findings will truly represent the phenomenon you are claiming to measure, then the data collected is valid.Therefore the above important points needs to be considered during data collection.

Answer:
62 dg = 0.62 dag
72,448 mm = 72.448 m
0.641 L = 641 mL
10,000 cm = 0.1 km
0.998 dL = 0.0998 daL
78,548 m = 78,548,000 mm
45 hg = 4500000 mg
97,123,582 mm = 97.123582 km

Which of the following would not be facilitated diffusion?
A: A water molecule passes through a semi permeable membrane
B: A large glucose molecule enters the cell through a pore protein
C: An amino acid exit the cell through an integral protein
D: A chlorine ion (CI-) unlocks a protein channel, and passes through
Answer:
A. A water molecule passes through a semi permeable membrane
Explanation:
Facilitated diffusion is the diffusion of a molecule without any assistance from a protein or protein channel.
In facilitated diffusion, a molecule will diffuse by itself through a semi permeable membrane, such as the cell membrane.
Answer choices B, C, and D are incorrect because they are all examples of facilitated diffusion. The molecules required assistance from a protein.
Answer choice A is correct because the water molecule was able to pass through by itself.
So, the correct answer is A. A water molecule passes through a semi permeable membrane
describe the human population growth curve over the past 10,000 years, and identify the type of population growth curve it represents
p.s I will give brainless
Explanation:
Global human population growth is around 75 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7 billion in 2012.
Although the direst consequences of human population growth have not yet been realized, exponential growth cannot continue indefinitely.
In the late 1970s, China’s “one-child” policy tried to control population growth, but restrictions were relaxed in the early 2000s.

During Anaerobic respiration:
A. glucose is converted into Lactic Acid.
B. glucose is converted into ATP.
C. ATP is converted into Lactic Acid.
D. glucose is not used as the energy source, since there is no oxygen.
During the process of anaerobic respiration, glucose is converted to lactic acid in the absence of oxygen. So the correct option is A.
What is anaerobic respiration?The type of respiration in which the sugars are broken down in the absence of oxygen. Here the final electron acceptor is not oxygen. The organisms that perform anaerobic respiration have evolved to use other substances as their electron acceptors.
Aerobic respiration happens in presence of oxygen. In both of these types of respiration, glucose is broken down into pyruvate and then it enters a series of reactions using an electron transport chain to produce ATP. This is where they require a final electron acceptor which can be oxygen, nitrate or sulfates etc.
The process of breakdown of glucose is called glycolysis. and after that two pyruvate molecules are produced. In anaerobic respiration, these molecules undergo reactions in the cytoplasm to produce ATP with the help of sulphur, sulfates, nitrates, fumarates etc as the final electron acceptor.
Anaerobic respiration produces less ATP compared to aerobic repiration.

bacteria are advantageous as well as disadvantageous. why
Answer:
ADVANTAGES:
Bacteria are involved in production of many food products such as yogurt, cheese, pickles, etc.
Bacteria break down waste material so that our environment is not permanently cluttered with garbage, dead bodies, etc.
Bacteria are responsible for the production of important essential compounds that are necessary for life such as vitamin K production by E. coli in the gut
DISADVANTAGES:
Some bacteria cause infections or produce toxic substances that are a threat to life and/or health.
Bacteria cause spoiling of food so that it does not keep as long as we may desire.
Some bacteria may cause infections of plants, threatening our food supply or ornamental plant.

Thoroughbreds are an example of a type of horse that results from selective breeding. However, not all thoroughbreds have the traits that are most desired. How is it possible to breed thoroughbreds but not have a horse with desired traits such as a fast runner?
In selective breeding, when crossing individuals that express the desired phenotype but are heter0zygous for this character, their offspring might express the undesired trait.
--------------------------------------
The main goal of selective breeding is to get individuals -plants or animals- with the desired traits. These traits make them better, according to the breeder's interest. The interest is to produce individuals with the same reproductive capability, adaptability, capacity, and general phenotype as the original pure line.
To get a generation of individuals expressing the desired traits, the breeder must select parents that have the characteristics of interest. Many or some animals of the progeny might inherit the desirable phenotype.
In general, pure and almost identical animals with the desired traits are produced after many generations of inbreeding. These are the pure-bred individuals and are the product of many selective crosses.
Pure-bred (true-bred) animals are h0m0zyg0us dominant or recessive for the desirable traits. The progeny of the same line express similar phenotype and performance to the ones of their progenitors.
Many problems are associated with selective breeding and the production of pure lines.
In the exposed example, let us say that the desired trait is running speed and that there is only one autosomal gene that codes for run speed.
the dominant allele F expresses the trait fast runnerthe recessive allele f does not express the trait fast runnerSo, FF and Ff individuals will be able to run fast, while ff individuals will not.
Probably the breeder does not know the genotype of the animals, so this person crosses the horses according to how fast they run -phenotype-. If the breeder wants to get fast runner animals, he/she will only choose horses with this trait, which might be either FF or Ff.
If the breeder chooses two heter0zyg0us individuals, there are 75% of getting horses with the desired trait and 25% of chances to get horses with the undesired trait -h0m0zyg0us recessive genotype ff-.
The breeder needs many generations of inbreeding to get only horses that are fast runners.
