Explanation:
In the non-random-mating exercise the percentage and frequency data for the genes were unaffected by the non-random mating. True False
Answer:
False
Explanation:
When non-random mating is being carried out, percentage and frequency data are usually affected because non-random mating have the tendency of changing the gene frequencies in a population. These non-random mating usually occurs when individuals choose to mate with superior physical traits or as a result of physical accessibility. The phenotypic characteristics are also greatly influenced by the biotic and abiotic environment they dwell in or other physical characteristics.

How does a stormwater runoff system store water?
Stormwater that cannot be directed back into rivers or streams is stored in
Answer:
Stormwater that cannot be directed back into rivers or streams is stored in Retention Basin's
Explanation:
Storm water that cannot be directed back into rivers or streams is stored in Retention basin.
What is Retention basin?A retention basin is also called a wet pond, wet detention basin, or stormwater management pond. It is defined as an artificial pond with vegetation around the perimeter and a permanent pool of water in its design.
Retention basins usually allow water to percolate through the soil and then into a shallow groundwater aquifer, whereas this basin can be man-made or a natural form of depression in the soil, which are closed systems, constructed in such a way that there is no storm water access to natural water bodies.
These are used to intercept and distribute rain runoff, which in turn helps prevent flooding which are often landscaped with a variety of grasses, shrubs and/or wetland plants to provide bank stability .
Thus, storm water that cannot be directed back into rivers or streams is stored in Retention basin.

Which of the following is NOT a characteristic of a monocot?
Flower parts in multiples of three
Major leaf veins reticulated
Embryo with single cotyledon
Pollen with single furrow or pore
Answer:
Embryo with single cotyledon
Explanation:
Monocot, also known as monocotyledonous plants are a group of flowering plants (angiosperms) that possess one seed-leaf or cotyledon, which is contrary to the two-seed leaves possessed by dicots. Monocot plants have other characteristics that differentiate them from dicots as follows:
- Their flower parts are in multiples of three.
- It's major leaf veins are reticulated
- Pollen with single furrow or pore
However, the embryo of monocots are with a single cotyledon.

Once you inoculate the rabbit plasma containing media for the coagulase test, how long do you wait to read the sample results
Answer:
12 to 14 hours
Explanation:
The coagulase test may be called an overnight incubation test and is used to find the presence of bound coagulase that are attached to the bacterial walls. It take between 12 to 14 hours to read the sample result. This period is equivalent of an overnight incubation.
3. On a particular planet, it takes 850 J for a 50 kg remote probe to launch
itself up 2 m. What is the gravitational field strength on the planet?
Answer:
the gravitational field strength is 8.5 N/kg .
Explanation:
PE = mgh
where,
PE is Potential Energy
m is the mass
g (a) is the acceleration
h is the height
Substitute the value we get
→ 850 = 50×a × 2
→ 850 = 100×a
→ a = 850/100
→ a = 8.5m/s²
Acceleration is 8.5m/s².
Now, Calculating the Gravitational Field Strength
Which of the following would lead to an increase in species biodiversity in Florida?
A.releasing snails from South America into the wild. В.
letting wild boar from England invade people's farm land
C.
clearing land for a new entertainment theme park
D. protecting an endangered species in state or national forests
Answer: D
Explanation:
Ensuring that they don't lose their habitat and protecting them is key. Not adding in other invasive species or overexploitation. Conserving would cut the pollution (and if done globally it would cut back global warming). So if we protect the current species more will come or the current will evolve and be able to reproduce.
Protecting an endangered species in state or national forests would lead to an increase in species biodiversity in Florida.
What are Endangered species?A species that is threatened with extinction in the near future, either globally or within a certain political jurisdiction, is known as an endangered species.
Invasive species, habitat degradation, poaching, and other issues may put endangered animals in danger. Numerous species have their worldwide conservation status listed on the IUCN Red List, and a number of other organizations evaluate the condition of species in specific regions.
Many countries have laws that preserve species that depend on conservation, such as those that prohibit hunting, limit land development, or establish protected areas.
Therefore, Protecting an endangered species in state or national forests would lead to an increase in species biodiversity in Florida.

what is allele frequency?
Answer:
The correct answer would be - D. the distribution of alleles in a population.
Explanation:
Allele frequency in population genetics is the term used to provide the amount of the different alleles in particular loci. In other words, it is the distribution of alleles in a population.
The term allele frequency refers to the fraction of the copies of the gene of the alleles in a known population. It can be calculated by the number of allele present of interest divided by total number of alleles in a population.
