Answer:

Due to over-pumping of water.

Explanation:

The aquifer around the Los Angeles are in California could be susceptible to an impact by a Tragedy of the Commons because the people used more water than the aquifer receives. The excess use of water from the aquifer through the well causes depletion of water which results in the shortage of water to fulfill the needs of existing population so it is wise to use water efficiently and used lower or equal water the aquifer receives in order to maintain level of aquifer.

Answer: e.  All answers are correct

Explanation:

Genetically Modified Organisms (GMOs) are living organisms whose characteristics have been changed, using genetic engineering techniques, to introduce genes from other species. These techniques make it possible to separate, modify and transfer parts of the DNA of one living being (bacterium, virus, plant, animal or human) to introduce it into that of another. Thus, different organisms can be given new characteristics or properties that they did not have before.

Examples of GMOs include microorganisms such as bacteria or yeasts, plants, insects, fish and other animals. These organisms can be the source of genetically modified foods, or be used in scientific research to produce goods other than food.

Possible genetic modifications that can be used include mutation, insertion and deletion of genes. When genetic material is inserted it usually comes from another species, similar to the horizontal transfer that occurs in nature. To artificially produce this transfer it is usually necessary to resort to different techniques. Genes can be incorporated into a virus or they can be physically injected into the cell nucleus with an ultrafine needle. Other techniques take advantage of the ability of certain organisms such as lentiviruses or some bacteria such as Agrobacterium tumefaciens to transfer genetic material to animals and plants.

a. Golden rice: It is variety of rice produced through genetic engineering, biosynthesizing the beta-carotene (pro-vitamin A) precursors in the edible parts of the rice grain.

b. Animals expressing antibiotics to prevent illness: Animals do not express any antibiotic. So they can only express it if they are genetically modified.

c. Fish expressing genes that allow them to mature faster than normal fish: These fish must have a gene from another species, so that they can express characteristics that make them faster.

d. BT corn: Bt corn is a type of transgenic corn that produces a protein of bacterial origin. The Cry protein, produced naturally by Bacillus thuringiensis, is toxic to stalk borer larvae, which are killed by eating Bt corn leaves or stalks.

e. All answers are correct, this is the right answer.

A plant grown in low light will have darker flower color while a plant grown in bright light will have lighter flower color.

The plants which have the ability to survive in the high intensity of sunlight they are called heliophytes.  

Prosopis, Betula, Teak, etc are the examples of heliophytes.The plants which grow in low light intensities are called Sciophytes. Example includes Aegle, Nycanthes.

Answer:

The correct answer is - A. 25%.

Explanation:

In humans, the blood group system is known as the ABO system where blood groups A and B are codominant and O blood group is recessive. The genotype of the A blood group could be AA or AO similarly for the B blood group genotype would be BB or BO, for the O blood group OO whereas for the AB blood group both A and B alleles should be present together.

Cross: AB blood type father with an A blood type mother (genotype AO)

Gametes: A, B and A, O

Punnett square:

       A       B

A    AA     AB

O    AO    BO

Here, there are 25% chances of AB blood group offspring 50% for the A blood group (AA and AO) and 25% B blood group (BO).

Answer:

The correct answer is - parasitic.

Explanation:

The Maculinea Alcon butterfly has a unique relationship with species of Myrmica ants. The butterfly's caterpillars picked up by passing Myrmica ants, and take to their nests where this caterpillar makes sounds like the queen ants, and to this sound, all ants protect and feed this caterpillar instead of other ants.

Normally there is a mutualistic relationship between ants and caterpillars but in the case of The Maculinea Alcon caterpillar and Myrmica ants, there is a parasitic relationship.

Answer:

The stable, end stage of ecological succession in which the plants and animals of a community use resources efficiently and balance is maintained by disturbances such as fire. The ultimate goal of ecological succession. After a natural disaster and continues until a climax community is reached.

Explanation:

The ultimate role of ecological succession in an environment is to reach the equilibrium in an ecosystem.

This event involve in the steady and gradual change in a species of a given area with respect to the changing environment is called as ecological succession.

The changes are inevitable process where all biotic components of the ecosystem keep up with the changes in our environment.

This process ultimately reach equilibrium in the ecosystem and the community that achieves this referred as a climax community, where some species increase in number and others decrease.

The communities that undergo changes sequentially in an area is called sere, so it is also called as seral stage or seral community.

Evolution has taken place simultaneously with that of ecological succession, so all the communities we observe are the result of ecological succession.

A food chain represents one possible pathway that energy and matter can take in an ecosystem, whereas food web contains multiple, interconnected food chains and describes how energy and matter moves through an entire ecosystem. Thus, the correct option is A.

A food chain is a component of the food web. It represents a unidirectional flow of energy and matter, that is one producer will have only one primary consumer which in turn will have only one secondary consumer, and then a single predator.

However, in the food web, the producer will have several primary consumers which in turn will have many secondary consumers and predators. A single consumer can consume multiple components from the food web.  

Thus, the correct option is A.
