You sample 1,000 individuals from a large population for the mn blood group, which can easily be measured since co-dominance is involved (i.e., you can detect the heterozygotes). they are typed accordingly:
Co-dominance in the mn blood group means that both allele characteristics are expressed in the organism.
What is co-dominance?Co-dominance is a form of inheritance whereby two or more alleles for a given trait are both dominant such that when they both appear in an organism, the phenotype of that organism reflects the characteristic of both traits.
Co-dominance is usually seen in blood group typing.
In blood group typing, there are two alleles that A and B which are both dominant. When both alleles are present, the blood group is AB and the phenotype of the organism is a result of the properties of both alleles, thus allele A and B are said to be co-dominant.
Therefore, co-dominance in the mn blood group means that both allele characteristic are expressed in the organism.

What are 'prokaryotic organisms'? What are some examples?
Explanation:
Prokaryotic organisms are type of cells that are clearly different from eukaryotic cells (human or plant cells), since they lack nucleus and other type of organelles and differ with size. ( some of them have flagella which helps these cells to move)
Example: Any type of bacteria can be considered as a Prokaryotic cell
Prokaryotic organisms are organisms that lack a true nucleus or in other words that have a primitive nucleus. This includes bacteria, E-coli, etc.
What is the difference between prokaryotes and eukaryotes?Eukaryotes are the organisms that have a well developed nucleus. They also have membrane bound cell organelles. These are generally multicellular.
Prokaryotes have a primitive nucleus, and the organelles are also not membrane-bound. These are unicellular.
Prokaryotes are divided into bacteria and archaebacteria. Most of them are small, single-celled and relatively simple. Example cyanobacteria, bacteria, E-coli, etc.
Thus, the organisms like bacteria, which lack a true nucleus are called prokaryotes.

What happens if the amount of withholding taken from your pay is greater than the amount you owe in taxes?
Answer:
When it comes to taxes, less isn't always more because If you don't withhold enough from your paycheck, you may end up surprised at how much you owe Uncle Sam at tax time. And the chances that you are under-withholding taxes are higher than you may think.
Explanation: A 2018 report by the Government Accountability Office (GAO) suggested that a fifth of taxpayers might owe taxes in 2019 due to under-withholding.1 The concern was particularly significant that year due to changes in the 2017 Tax Cuts and Jobs Act. The updated W-4 form from the Internal Revenue Service (IRS) was fully implemented by 2021, and for some, those changes came as a surprise in the form of a more expensive tax bill.
However, no matter what tax year, it's important to withhold the correct amount from your paycheck to avoid underpaying the government.
If the amount of withholding taken from one's pay is greater than the amount owed in taxes, the taxpayer will receive a refund when they file their tax return, as described in Option A.
What is a tax refund?The amount of tax withheld is based on the employee's income, marital status, and the number of allowances they claim on the form, and the employer then withholds the appropriate amount of tax from the employee's pay and sends it to the IRS on their behalf. At the end of the year, the employee must file a tax return with the IRS, which calculates the total amount of tax owed for the year. If the amount of tax withheld from the employee's pay is greater than the amount they owe in taxes, they will receive a refund for the difference.
Hence, the taxpayer will receive a refund when they file their tax return that is present in option A.

Pioneer species move into an area after a disturbance that forms new land without soil.
Pioneer species are the first organisms to inhabit a region that has experienced a primary succession.
How do pioneer species arrive?
Primary succession begins in barren areas, such as on bare rock uncovered by a retreating glacier.
The first residents are lichens or plants that can survive in such an environment. Over hundreds of years these “pioneer species” transform the rock into soil that can support simple plants such as grasses.
Thus, Pioneer species move into an area after a disturbance that forms new land without soil.

Strom waves and ocean currents cause beach erosion.
What is beach erosion?
Sand is lost due to beach erosion, which is often caused by a mix of wind and water movement. Sand is moved to deeper water or to another coastal location by being scooped up off the beach. Beaches seem shorter and lower as a result of this process.
Sand particles make up the majority of beach deposits, and waves can quickly dissolve them.
These deposits are made up of terrestrial silt transported to the coast by rivers, marine sediment reworked from offshore deposits onto the coast, and sediment created by wave erosion of coastal landforms.
Therefore, Strom waves and ocean currents cause beach erosion.

Answer:
micro-beads can cause blockages in the digestive tracts of aquatic organisms.
This can prevent digestion of food hence the organism will eventually die of starvation.micro-beads can increase organic matter in a pond hence killing the aquatic organisms present.
This increases the number of decomposers which grow rapidly and use a great deal of oxygen during their growth and lead to depletion of oxygen as the decomposition process occurs. A lack of oxygen can kill aquatic organisms.Explanation:
