macromolecules are large molecules that are formed by the joining of smaller units. Lipids fit that description, but they aren't polymers because they are made up of smaller units of different kinds (like glycerol and fatty acids) rather than monomers that repeat themselves
Leon was a relatively successful attorney before developing schizophrenia. He has now stopped working and prefers to wander the streets in preparation for an "airlift" of humans by extraterrestrials. He has lost all his property and stays on the streets. His poverty has further aggravated his psychotic symptoms. Leon's story lends credibility to which hypothesis regarding the relationship between social class and schizophrenic symptoms?
A. Social causation hypothesis
B. Milieu hypothesis
C. Downward social drift hypothesis
D. Double bind hypothesis
Answer:
C. Downward social drift hypothesis
Explanation:
In the scenario, being described Leon's story lends credibility to Downward social drift hypothesis. This hypothesis states that there is a clear relationship between mental illness and social class, in which the illness leads the individual to have a downward shift in social class. This is the case with Leon, since he was an upper-class individual until he developed schizophrenia, which ultimately caused him to drop lower and lower in social classes. All the way down to homeless.

Which characteristic describes the whale but not its food source, the phytoplankton? The whale is heterotrophic. The whale has cell walls. The whale is unicellular. The whale is a prokaryote.
Answer:
A. The whale is heterotrophic.
Explanation:
The whale is an aquatic animal that is heterotrophic in nature. Heterotrophic means that this animal lacks the ability to manufacture its own food because it depends on plants and animals as a source of food energy. Since the Whale is dependent on phytoplankton for food, this means that it is not a producer of food and as such is heterotrophic.
Phytoplankton is a marine alga. Algaes are prokaryotes and this means that they are unicellular animals without a membrane-bound nucleus. The Cell wall is mostly a characteristic of plants. So the first option is a perfect description of the whale and not its food source which is the phytoplankton.
Answer:
ExplanationThe whale is heterotripic
Darwin's Hypothesis of Evolution by Natural Selection included the observation that populations often grow faster than the food supply and therefore individuals need to compete for resources. Darwin borrowed this idea from the work of:
Answer:
Thomas Malthus on his essay on population.
Explanation:
Malthus concluded that human population grow faster than the available resources in their environment.However,no matter how this population increases,selection pressure like famine,natural disasters,always keep the population in check,thus maintaining the population size within moderate levels.
He believed the weakest in the population (with little resistance to the selection pressure) will die,thereby reducing the population, encouraging the survival of the fittest,and stabilizing and preventing expulsion.
Darwin, assumed that the surviving organisms in the population must have inherited certain characteristics/traits from their parents,which make them to resist the selection pressures.He called the surviving ones the survival of the fittest by natural selection.
During genetic engineering, what is the function of a Ligase enzyme? A. To create a plasmid. B. To bond the target gene to the plasmid with covalent bonds . C. To create sticky ends to bond to gene to the plasmid. D. To cut the DNA at a Recognition site.
Answer:
C
Explanation:
In DNA cloning, restriction enzymes and DNA ligase are used to insert genes and other pieces of DNA into plasmids.
Genetic engineering is the field that uses technology and deals with genetic material. It uses the ligase enzyme that joins the sticky ends of genes to the plasmid. Thus, option B is correct.
What is ligase enzyme?Ligase is a protein enzyme that is involved in catalyzing the large fragments of the genetic material with the plasmids to make recombinant DNA. It establishes new chemical bonds.
In genetic engineering, the ligase enzyme links the gene of interest to the plasmid's restriction ends (sticky end). They allow the integrity of the genome by joining the phosphodiester backbone of the genetic material.
It joins the gene with the restriction ends of the plasmid by the concomitant hydrolysis (covalent bonds) process of chemicals from large molecules. It allows the formation of the complete genome that now can replicate.
Therefore, option B. ligase bonds the gene with plasmids.

Why do you think the eukaryotic DNA requires multiple origins of replication?
A.
Multiple origins help make more copies of the same DNA simultaneously.
B.
Eukaryotic organisms have unique DNA strands for each specialized cell.
C.
Eukaryotes do not have topoisomerase, so multiple origins are created due to tension from unwinding of DNA strands.
D.
Eukaryotic DNA is much larger and replication at multiple origins helps reduce the time required for whole genomes to replicate.
E.
Multiple origins of replication ensure that there are no lagging strands and replication takes place at the same pace.
.
Answer:
D.
Explanation:
Prokaryotic DNA exhibit single origin of replication while eukaryotic DNA has multiple origins of replication because eukaryotic DNA is much larger and multiple origin of replicate helps them to replicate the whole genome in short time duration.
Large DNA of eukaryotes contain high amount of material to be replicated and multiple origin sites helps them to replicate in short time. DNA replication initiate at each origin site independentaly and terminate at corresponding termination sites.
Hence, the correct answer is D.

Both the full body plate type and the half body plate trait are also present in an ocean near the lake. Where would you expect a higher occurrence of the full body plate trait, in the lake or the ocean? Explain your answer.
Answer:
In the ocean
Explanation:
Ecological divergence leads to selection of essential traits against migrants and hybrid species. The full body plate type traits requires attention for occurrence in an environment which is free from issues such as resource limitation or predator attacks. In vast ocean spaces , resources are not a limiting factor in ocean and also there is no risk of predators as there is huge chunk of space, thus, full body plate type will occur in higher number in the ocean.
hope it helps you..
The place where there would be a higher occurrence of the full body plate trait would be:
In the ocean
Based on the given question, we can see that when the ecological divergence which helps the full body plate type to have a higher occurrence in the lake because there is a need for attention.
With this in mind, we can see that in the ocean, there is the higher chance for the full body plate because of the absence of predators and the abundance of resources in the ocean.

Explanation:
because.
Gametes are produced as a result of meiosis.
What are the different stages of meiosis ?
The meiosis is divided into Meiosis I and Meiosis II, each stage subdivided into sub phases.
In prophase I of Meiosis I, nuclear envelope disintegrates, Chromosomes condensed and Spindle fibres are formed.
In Prometaphase II, Spindle fibres bind to the chromosomes at the centromere.
In Metaphase I, homologous chromosomes align at the equatorial plate.
Anaphase I where chromosomes are move towards the opposite poles.
In Telophase I, Spindle fibres disappear, reformation of Nuclear envelope; In Cytokinesis I, 2 non-identical diploid daughter cells are produced.
In Prophase II of meiosis II same event occur like prophase I.
In Metaphase II chromosomes align along the equatorial plate; In Anaphase II, Sister chromatids move to opposite poles.

Which of these would be considered a transgenic organism? a human treated with insulin produced by E. coli bacteria a rat with rabbit hemoglobin genes a bacterium that has been treated with a compound that affects the expression of many of its genes a fern grown in cell culture from a single fern root cell a houseplant propagated from the cuttings of another houseplant
Answer:
a rat with rabbit hemoglobin genes
Explanation:
When the genome of an organism is modified in the field of genetic engineering,by transplanting the gene(DNA) from one organisms to another,(by vectors) or alteration of the gene components,the resulting organism produced or formed is called Transgenic organism.
This process of genetic engineering makes use of recombination of genes to alter the genome of the transgenic organism.
Thus by transferring to rat ( the DNA for Hb) as the rabbit Hb,the gene( or genome) for producing Hb in tats has been modified by that of rabbit.Hence Rat is said to transgenic.
Besides animals crop plants are also genetically modified.Thus the genome of some crops are altered to resist herbicides and pesticides. Some species of rice (golden rice)have been modified to add certain vitamins to improve the nutritional values.
Genetically modified bananas as edible vaccines are another example
