Which of the following are formed during photosynthesis?
A. C6H1206 and 02
B. C2H4O2 and H20
C. C2H4O2 and 02
D. C6H1206 and H20
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

9. A finch population has genetic diversity. Some of the finches have an allele that gives them
longer beaks. Due to pollution, the ecosystem changes and seeds become harder to find. The
finches with long beaks can dig the seeds out more easily than the finches with short beaks.
a) Which type of bird is selected for in the polluted ecosystem?
b) How will the allele frequency change in the finch population?
c) is this an example of natural selection explain
Answer:
A) the finch with the longer beak
B) the allele will continue to become more prominent as the smaller beak birds die off
C) Yes, the birds with the longer beaks will continue to live on because the birds with the smaller beaks can’t find the seeds as easily.
Explanation:
Seeds are harder to find, so finches with larger beaks get selected in a polluted environment. This is a natural selection. If this continues, then the alleles for short beak will vanish.
What is natural selection?
Natural selection is a process in which nature selects an organism that can fit well. If an allele is selected in a population and present for a longer time, then it replaces other alleles in that population. Example: In a population, both short-beaked and long-beaked finches are present.
Due to pollution, long-beaked finches are able to find more seeds than short-beaked finches. Here, nature favors long-beaked finches over short-beaked finches. If this continues for a longer generation, then alleles for the short beak will vanish. Only alleles for long beaks will be in the population.
Hence, long-beaked finches are selected. It is an example of natural selection. The allele frequency of the long beak will increase while decreasing for the short beak.

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.

What happens when organisms populate a new area and are isolated geographically from other populations of the same species?
Answer:
The geographically isolated population will acquire genetic differences that eventually will lead to its speciation
Explanation:
Geographic isolation is a biological process produced by the physical separation between organisms of the same species, which may be caused by different types of geographical barriers such as, among others, mountains, earthquakes, rivers, etc. Geographic Isolation produces genetic differences between the separated groups. Over time, these genetic differences will lead to the reproductive isolation of the new population, thereby leading to the formation of a new species in the course of evolution, in a mechanism referred to as speciation.

The graphic shows the citric acid cycle. A diagram of the citric acid cycle is shown. Acetyl C o A enters the citric acid cycle and combines with a 4-carbon compound to form citric acid. During the citric acid cycle, what happens to acetyl-CoA? It enters the citric acid cycle and gains carbon dioxide to form citric acid, and gains more carbon dioxide through redox reactions to form a 4-carbon molecule. It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule. It enters glycolysis and associates with a 5-carbon molecule through redox reactions, forming another acetyl-CoA molecule. It enters the citric acid cycle and associates with a 4-carbon molecule, forming a 5-carbon compound, and then through oxidation reactions regenerates the 4-carbon molecule.
Answer:
It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.
Explanation:
Acetyl-CoA(2C) associates with oxalacetate(4C) to form citric acid(6C). Then through redox reactions, CO2 molecules result from decarboxylation (COOH becomes R-(R1)CH-R2). And through dehydrogenation H2 molecules are incorporated in NADH+ in FADH2, resulting in the 4-carbon molecule at the beginning (oxalacetate). That's why it's called a cycle(Kreb's cycle or citric acid cycle)
In the citric acid cycle, when acetyl-CoA enters the cycle, it associates with a 4-carbon molecule (Oxalacetate), forming citric acid, and then through redox reactions regenerates the 4-carbon molecule (Oxalacetate).
--------------------
The resumed steps of the Citric acid cycle are as follows,
1) Acetyl CoA joins an oxaloacetate molecule, which is a 4C molecule. They release the CoA group and form a 6C molecule called Citrate.
Acetil CoA + Oxalacetato → Citrato + CoA group
2) Citrate turns into an isomere Isocitrate
3) Isocitrate oxidates and release 1 CO₂ molecule, producing an α- ketoglutarate molecule -this is a 5C molecule-. Meanwhile, NAD+ reduces to NADH.
Isocitrate + NAD+ → α-cetoglutarate + CO₂ + NADH
4) α-ketoglutarate oxidates and release 1 CO₂ molecule, producing a 4C molecule, which joins a Coenzyme A producing Succinyl-CoA. Meanwhile, NAD+ reduces to NADH.
α-cetoglutarate + NAD+ → 4C molecule + CO₂ + NADH
4C molecule + Coenzyme A → Succinil-CoA
5) CoA from Succinyl-CoA is substituted with a phosphate group, which then forms ATP. The final product is Succinate and ATP
Succinyl-CoA + Phosphate group + ADP → Succinate + ATP + CoA
6) Succinate oxidizes and forms Fumarate, a 4C molecule. FAD+ forms FAH₂
Succinate + FAD+ → Fumarate + FADH₂
7) A water molecule and Fumarate produce Malate, which is another 4C molecule
Fumarate + H₂O → Malate
8) Finally, malate oxidizes and oxalacetate regenerates -the initial 4C compound-. NAD+ reduces to NADH.
Malato + NAD+ → Oxalacetate + NADH
So, when acetyl-CoA enters the cycle, it associates with a 4-carbon molecule (Oxalacetate), forming citric acid, and then through redox reactions regenerates the 4-carbon molecule (Oxalacetate).

Instructions on how to control your cells are contained in what part of the DNA?
Answer:
Genes
Explanation:
The genes are specific fragments of the DNA molecule that contain the information necessary to synthesize different types of RNAs, including messenger RNAs (mRNAs) which are subsequently translated into proteins required for different cellular functions including replication, cell cycle, proliferation, apoptosis, etc. Genes are first transcribed to RNA during transcription. In eukaryotic organisms, the genes contain both exonic and intronic sequences that are jointly transcribed into the primary mRNA, and then the introns are removed during RNA splicing. The genes have a specific initiation signal sequence known as start codon (AUG) and termination codons (UGA, UAA, UAG) that terminates the translation of the mRNA.

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.
