Ecotourism can provide an incentive for local people to preserve the environment in order to attract more visitors, but sometimes development is done with little planning for long-term environmental impacts. On a small island in the Caribbean, a local group is considering opening a resort for ecotourism. If they wish to build a sustainable and ecofriendly business, what should be the next steps in their plan?
A. Investigate the ecological impacts and gather evidence on which to base their decisions
B. Hire an agent to locate a suitable property and start developing infrastructure
C. Market the development to investors and explain ecotourism to them to raise money for the resort
D. Determine what types of activities the resort will offer and hire staff
Answer: The next steps in their plan should be to (Investigate the ecological impacts and gather evidence on which to base their decisions). The correct option is A.
Explanation:
ECOTOURISM is defined as the visitation of individuals (tourist) to natural areas that conserve the environment and sustains the well-being of the local people. It has to do with the interaction of the biotic components of the natural environment by tourists. This has the advantage of providing an incentive for the local inhabitants but can cause a long term negative environmental impact of not properly planned.
Conservation of these natural resources improves the quality of lives. It enables the inhabitants to live in a clean and healthy environment (eco-friendly). To set up a tourism center, certain rules and regulations needs to be met in order to avoid endangering both the biotic and abiotic components of the ecosystem. Therefore these local groups should investigate the ecological impacts and gather evidence on which to base their decisions. This would help conclude if a particular selected environment is conducive.

3.1.3 Calculate the actual width of the cholera bacterium between points X
and Y. Give your answer in micrometers (um). Show all working
(2)
Answer:
Looks hard
Explanation:
I dont know how to do this
Actual width of the cholera bacterium between points X and Y is: 6.5 mm × (1,000 um/1 mm) = 6,500 um.
What is cholera bacterium?The cholera bacterium is a single-celled, rod-shaped bacterium called Vibrio cholerae. It is a type of bacteria that can cause severe diarrhea and dehydration if ingested through contaminated water or food.
The actual width of the cholera bacterium between points X and Y can be calculated as follows:
Width of the bacterium on the diagram = 0.06 cm
Magnification = 50,000 times
Actual width of the bacterium = (width on the diagram) / magnification
= (0.06 cm) / (50,000)
= 0.0000012 cm = 0.012 µm (micrometers)
Thus, the structure C is flagellum and its function is to provide locomotion.

AMP-PNP is a non-hydrolyzable analog of ATP that can bind to proteins in a similar manner as ATP but is no longer hydrolyzed. Predict what would happen to helicase activity if AMP-PNP were added to a DNA replication reaction. Choose one: A. Helicase would function normally, since AMP-PNP is not the same as ATP and would not bind to helicase. B. Helicase would function normally, since AMP-PNP is an analog of ATP and would function in the place of ATP. C. Helicase would function faster than normal, since the AMP-PNP is not hydrolyzed. ATP binding induces conformational changes, but hydrolysis slows DNA unwinding by helicase. D. Helicase would no longer function, since the AMP-PNP is not hydrolyzed. ATP binding and hydrolysis induce the conformational changes that facilitate DNA unwinding by helicase.
Answer:
The correct answer is - D. Helicase would no longer function, since the AMP-PNP is not hydrolyzed. ATP binding and hydrolysis induce the conformational changes that facilitate DNA unwinding by helicase.
Explanation:
During the replication process, helicase unzips or unwinds the double-stranded DNA. Helicase is a motor protein that uses ATP molecule hydrolysis in order to break the H-bonding between the strands of DNA.
If AMP-PNP added during DNA replication then it will bind to helicase and remains bound to helicase due to fact that it is a nonhydrolyzable ATP analog.

The change in the circled offspring’s genotype was caused by a mutation. A mutation is a change in a gene. Mutations happen when a mistake is made when a cell’s chromosomes are copied. How might mutations introduce variation into a population? EXPLAIN
there will be changes in the number of chromosomes
A mutation is a change in a gene. Mutations happen when a mistake is made when a cell’s chromosomes are copied. Mutations introduce variation into a population by changing the genome and introducing new changes that might or might not be beneficial.
What is mutation ?It is defined as the change that is caused in terms of certain type of change that is introduced by knowingly or unknowingly.
A mutation is a change in a gene. Mutations happen when a mistake is made when a cell’s chromosomes are copied. Suppose if a genetic codon AUG has to be inserted by the mRNA which earlier has to code for methionine and was a start codon but with time U got replaced and the new codon is made which changes the expression.
Mutations that are born are none other than insertion of some other amino acids or codon , deletion of some bases and other mutations as well which leads to the variation in the species.

Neutral theory proposes that
A) molecular clocks are more reliable when the surrounding pH is close to 7.0.
B) most mutations of highly conserved DNA sequences should have no functional effect.
C) DNA is less susceptible to mutation when it codes for amino acid sequences whose side groups (or R groups) have a neutral pH.
D) DNA is less susceptible to mutation when it codes for amino acid sequences whose side groups (or R groups) have a neutral electrical charge.
E) a significant proportion of mutations are not acted upon by natural selection.
Answer:
The correct answer is E) a significant proportion of mutations are not acted upon by natural selection.
Explanation:
The neutral theory, proposed by Motoo Kimura in 1968, proposes that part of the molecular variability produced by mutations that exists in populations is natural variability, that is, a large part of the genetic variation observed in populations is due to random fluctuation of genetic variants that are neutral, on which natural selection hardly acts, so they are not an evolutionary force since they do not contribute predominantly to natural selection and proposes genetic drift as an evolutionary mechanism.

Explanation:
The GLUT transporter moves glucose through a transport protein in the same direction as its concentration gradient. The action of the glucose transporter is an example of _____________. The SGLT transporter uses the sodium concentration gradient created by the sodium potassium ATPase to move glucose against its concentration gradient. The action of the SGLT transporter is an example of _______________.
Answer:
The correct answer is - facilitated transport and secondary active transport.
Explanation:
GLUT transporter is a glucose transporter that helps in moving the glucose to its concentration gradient through the cell membrane. It is a transport protein that uses passive transport of facilitated transport that moves down their concentration gradient and therefore does not require chemical energy from ATP hydrolysis in the transport step.
Sodium-based GLUT or SGLT is also a glucose transport protein that exhibits secondary active transport as it develops electrochemical potential difference by moving ions out of the cell membrane, this gradient allows the movement of ions and molecules.

A. They are more likely to reach carrying capacity.
B. They are more likely to have harmful mutations.
C. They are more likely to become an invasive species.
D. They are more likely to have some individuals adapted for survival.
Answer:
D
Explanation:
Looks correct if you go with D
Genetically diverse population make a species more likely to survive a change to the environment because they are more likely to have some individuals adapted for survival. Thus, the correct option will be D.
What are Genetic variations?Genetic variation is the difference in the DNA molecule among different individuals or the differences between different populations of a species. The multiple sources of genetic variation include changes which could result from mutation and genetic recombination.
Mutations are the ultimate sources of genetic variation in a population, however other mechanisms, such as genetic drift, also contribute to it, as well. The populations which are genetically diverse are more likely to have some individuals adapted for survival.
