Answer and Explanation:
Example of a food-web:
(1) Algae --> (2) Protozoas --> (3) Krill --> (4) Cephallopods --> (5) Medium sized dolphin --> (6) Large Dolphin
The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one.
1) The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. In this example, the autotroph organisms are algae, that make use of sunlight and inorganic matter.
The next links are the consumers:
2) Herbivores are primary consumers and feed on producers. In this example, herbivore organisms are protozoan.
3) Krills are the secondary consumers and feed on protozoans.
4) Some species of cephalopods feed on krill, among other species.
5) Specialized Cetaceans such as the Risso´s dolphin, feed especially on cephalopods, as they lack upper teeth and they only have a few teeth in their jaws.
6) The killer whale is a big sized-dolphin and a very important predator. It feeds on many animals, and one of them is the Risso´s dolphin.
Answer:
<em>The correct option is C) Plants</em>
Explanation:
Option A is false because the cell cannot be an animal cell. This is because an animal cell does not possess a cell wall.
Option B is false because the cell cannot be a bacterial cell. This is because a bacterial cell does not have a nucleus. Their genetic material is dispersed inside the cytoplasm.
Option C is correct because all the organelles, a cytoskeleton, mitochondrion, nucleus, cell wall, and ribosomes, are present inside the plant cells.

Explanation:
Education is seen as the golden ticket to a better life, however this ticket is not being taken by many young individuals at the perfect age to pursue higher education. For various reasons, students have no drive or interest in the benefits of the institutions that surround them. In the New York Times article “Bottom Line: How State Budget Cuts Affect Your Education,” Sarah Brown demonstrates how state spending to universities has dropped dramatically nationwide since 2008 and the numbers presented are staggering; some universities are experiencing cuts of more than 50%. The implications of what is happening here are dismal - spending cuts are “forcing many public universities to lay off faculty and staff members, postpone in new facilities and raise tuition fees.” Due to these massive reductions to funding colleges and universities, education is becoming less available to the general public due to increased cost. There seems to be no reasonable stance which successfully argues that education should not be provided to all individuals in a society. There is a plethora of research showing correlation between educational attainment and quality of life; it should be common understanding that education is no longer a privilege, but rather a right and a necessary resource. Students must realize the potential that surrounds them and the benefit that is provided by it.
Spending cuts and subsequent financial burdens are causing our country and its citizens to experience a major issue - many students are having education withheld from them due to the increasing cost of becoming educated. Education is an invaluable tool in liberating the minds of individuals to an elevated state of understanding and potential. It allows one to question and analyze the various going-ons of the world and its inhabitants. Education allows one to approach controversy and to form strongly validated, persuasive views. When a nation’s citizens become educated, they see a general improvement in quality of life and an improvement in their society. Education is of utmost importance in enhancing the lives of the individual and for allowing a society to develop and flourish.
Education is currently greatly privileged, with financial burdens serving to be a limiting force for many potential students. The ultimate tool to really increase the abundance of educational opportunities begins at lowering if not removing entirely, the tuition of college and treating it as a common good. Free college is not some mystical fantasy, as it has indeed existed in the past and still does exist in small institutions scattered across America. The notion of free college can only exist in the public institutions, however, as the cost of tuition is remarkably lower than that of private institutions.
Economic Growth and Stability
Many economists agree that education is directly correlated with economic growth and stability. Countries thrive when their educational systems thrive. In “Education and Economic Growth,” the authors greatly encourage school reform in order to improve education because it strengthens national economic competitiveness. They cite the National Commision on Excellence on Education in stating that “in order to keep and improve on the slim competitive edge we still retain in world markets, we must dedicate ourselves to the reform of our educational system.” The improvement of educational stances in countries promotes its economic standing and stability.
We can all understand that educated individuals bring in bigger paychecks than those who are lacking in their education. But are we aware of education’s true implications? George Schultz and Eric Hanushek write in the Wall Street Journal that education has tremendous economic ramifications. The more educated the citizens of a country are, the more likely their personal and societal economies are to develop and succeed. Essentially, “educational outcomes strongly affect economic growth and the distribution of income.” According to economists at Harvard University, the 60% to 70% rise in wage inequality is based on the degree of education for high school and college graduates. Education benefits entire countries as well. Schultz and Hanushek explain that the more educated the citizens of a country are the more the country experiences economic growth. Both on personal and national levels, education has been shown to increase economic growth and stability.
Answer:
2 out of 4
Explanation:
Let the allele for cleft chin be represented by A, while the alternate recessive version would be a.
A parent that is heterozygous for cleft chin would have the genotype Aa.
A parent without cleft chin would have the genotype aa.
Aa x aa
Aa Aa aa aa
Aa - cleft chinned = 2/4
aa - normal chin = 2/4
Thus, two out of every four (2/4) of their offspring would have cleft chin.
