--------------------------------------------------------------------------------------------------------------Question: Which type of bond forms between water molecules?
--------------------------------------------------------------------------------------------------------------Answer: Water is polar, and the dipole bond it forms is a hydrogen bond based on the two hydrogen atoms in the molecule. Hydrogen bonds are especially strong because the hydrogen atom in molecules such as water is a small, naked proton with no inner electron shell.

The cassava is an important food crop for people living in sub-Saharan Africa. In the 1970s, mealybug infestations destroyed harvests and people starved. A researcher who studied the mealybug in its native environment discovered a parasitoid wasp that was a natural predator. After extensive testing to determine safety, the parasitoid wasp was introduced into the sub-Saharan region with tremendous effect controlling the mealybug throughout most of Africa. This approach represented a form of
Answer:
Biological control.
Explanation:
The introduction of parasitoid wasp into the sub-Saharan region in order to control the population of mealybug throughout most of Africa. This approach represented a form of biological control because one harmful organism is controlled with the help of other living organisms that feed on them. This method is environmental friendly and good as compared to chemical method of removing harmful insects.
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.

Why does having a genetically diverse population make a species more likely
to survive a change to the environment?
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.
Therefore, the correct option will be D.

List at least 5 environmental problems caused by human populations inhabiting the earth. Propose some possible solutions that might address these problems.
Answer:
1 - Deforestation
2 - Industrial Fishing (mass fishing; when industries use those big nets to collect a ton of fish. y’know that Finding Nemo scene?
3 - Global Warming
4 - Poaching
5 - Pollution
Explanation:
Deforestation is destructive to our air quality, as well as the homes of wild life. This can and does causes animals to die, and not enough animals for the greater part of the food chain.
Industrial fishing is harmful to entire environments purely by there being a lack of fish for other animals to eat, as well as a large portion of the worlds fish being now absent because of this mass fishing.
Global Warming is caused by harmful gasses being released into our atmosphere, which is harmful for all life on earth when the earth’s temperatures are being raised.
Climate change in general is bad and caused by humans’ negative impact.
Poaching is illegally hunting animals. This leads to [if not already endangered] wild animals being endangered or extinct.
Pollution can go from anything to littering on the street or beach to industries dumping oil into our oceans, which is harmful for our water supply and all ocean wildlife.

A pack of Ramboulet sheep were imported from Australia to Pakistan in November. After some days, various sheep were suddenly died. Remaining of them were carefully examined by an expert veterinarian who found that sheep were extremely weak with yellowish mucus membrane. Sheep were gasping and it was examined that some of them are anxiously looking at their belly. He prescribed some emergency drugs along with fecal examination. Results showed presence of large quantity of parasite oocytes approximately ranging from 145 -155 um in length and 85-95um in width. How will you proceed with diagnosis as veterinarian? What is differential diagnosis and lifecycle of parasite?
Answer:
Through medication.
Explanation:
First I will apply medication that kills the pathogen that is present in the feces as well as good feel to maintain the health of sheep which was weak due to the pathogens. I have to apply vaccines that kills oocyst that is responsible for this infection. A differential diagnosis refers to a list of possible conditions or diseases that could be causing your symptoms. It can be obtained from your symptoms, medical history, laboratory results, and a physical examination. We can find out the disease through the symptoms that we observe from physical examination.

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.

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.
