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
Answers
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.

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
Answers
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.

A plasmid 41 twists and 6 right handed writhes. What is the Lk for this plasmid?
Answers
Answer: Lk for this plasmid = 47
Explanation:
The formula to compute Lk is given by :-
Topological Linking Number (Lk): Twist (Tw) + Writhe (Wr)
Given: A plasmid 41 twists and 6 right handed writhes.
i.e. Twist (Tw) = 41 , Writhe (Wr) = 6
Then, Topological Linking Number (Lk) for this plasmid : = 41+6
= 47
Hence, the Lk for this plasmid = 47

Sugars
O Joined sugar and phosphate
O Paired nitrogen bases
Answers
In the ladder analogy of the DNA molecule, the "steps of the ladder" are paired nitrogen bases.
What are nitrogen bases?The DNA molecule is made up of two strands of nucleotides that create a double helix as they coil around one another. The sugar molecule, the phosphate group, and the nitrogenous base are the three parts that make up a nucleotide. The nitrogenous bases serve as the ladder's rungs or "steps," pairing with one another to form hydrogen bonds that hold the DNA molecule's two strands together.
The nitrogenous bases adenine (A), thymine (T), cytosine (C), and guanine (G) are the four types found in DNA (G). The genetic code of an organism is made up of base pairs, which always couple adenine with thymine and cytosine with guanine. The genetic information that is transferred from one generation to the next is determined by the arrangement of these base pairs along the DNA molecule.

What would most likely happen to a cell undergoing mitosis if you introduced an inhibitor to Aurora B at prometaphase
Answers
Answer:
Nuclear division will not occur in that cell
Please find the explanation below
Explanation:
Mitosis is a type of cell division in which two genetically identical daughter cells form from a single cell. The mitotic process occurs in stages, which includes the PROMETAPHASE described in this question. Prometaphase is the second stage of mitosis i.e after prophase and before metaphase.
Prometaphase stage is characterized by the degradation of the nuclear envelope in order to allow the sister chromatids to be separated into opposite poles. Also, a protein called KINETOCHORE forms at the centromere in order for the microtubules to attach to them in subsequent stages.
If an inhibitor is introduced into the cell at PROMETAPHASE stage, the activities described above, which are important for the separation of the chromatids, will not occur. Hence, the likely effect on the cells is INABILITY of NUCLEAR DIVISION TO OCCUR.
The most likely outcome of the addition of an inhibitor to Aurora B in prometaphase of a cell undergoing mitosis is the fact that sister chromatid arms would not separate (Option B).
Aurora B is a crucial regulator of accurate mitosis that localizes to the chromosomes during prophase, the centromeres during metaphase, and the mitotic spindle during anaphase.During prometaphase, this protein (Aurora B) regulates the association of motor proteins with the kinetochore, which s a structure associated with duplicated chromatids in eukaryotic cells.The interactions of the kinetochores with microtubules of the mitotic spindle modulate the movement of chromosomes during prometaphase and metaphase, and subsequent segregation during anaphase.In conclusion, the most likely outcome of the addition of an inhibitor to Aurora B in prometaphase of a cell undergoing mitosis is the fact that sister chromatid arms would not separate (Option B).

itself up 2 m. What is the gravitational field strength on the planet?
Answers
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.

In the non-random-mating exercise the percentage and frequency data for the genes were unaffected by the non-random mating. True False
Answers
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.
