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.

Answer:
These are all examples of local anaesthetics a) marcaine(Bupivacaine) b) xylocaine(lidocaine) c) novocain(procaine) are all examples of local anaesthesia
Explanation:
Generally local anaesthetic are drugs used in clinical anaesthesia to block or suppress the sensation of pain at the specific region or part of the body where it was applied.The effect of the application depends on the dose applied and the period of application.
The work by inhibiting transmission of action potential as nerve transmission,through blocking of sodium channels. Thus depolarization is prevented,and nervous transmission to the brain (and therefore pain) is suppressed
Generally pain transmission fibres are blocked first,motor sensation are lost afterwards ,therefore touch sensation and pressure are the last to be lost by the local region.

Distinguish between pulmonary circulatory system and systemic circulatory system
Answer:
Pulmonary circulation only occurs between the heart and the lungs. Systemic circulation refers to the circulation of blood in which oxygenated blood is pumped from the heart to the body and deoxygenated blood is returned back to the heart. Systemic circulation occurs between the heart and the entire body.
Explanation:
Answer:
Pulmonary ciculatory system transports poor-oxygen blood from the heart to the capillaries in the lungs. The lungs transport the rich-oxygen blood to the heart.
Systemic circulatory system transports rich-oxygen blood from the heart to the capillaries in the body. The capillaries in the body transports the poor-oxygen blood back to the heart.
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.

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).

Which is one common property of inorganic substances? They are solid at room temperature. They are poor conductors of electricity. They contain carbon. They burn readily.
Answer:
They are solid at room temperature.
Explanation:
Inorganic substances are substances that does not have carbon and hydrogen. Most inorganic compounds are metals or alkali metals which make them to be able to conduct electricity.
They are solid at room temperature which make them to be poor conductor of electricity at solid state. In the solid state, the individual particles of a substance are in fixed positions to each other because there is not enough thermal energy to be able to overcome the intermolecular interactions between the particles.
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.

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.
how does the nucleus control which proteins are made by the ribsomes
Answer: They receive their “orders” for protein synthesis from the nucleus where the DNA is transcribed into messenger RNA (mRNA).

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.

The magmas established by regional metamorphism are also richly volatile in nature.The affectionate eruption has become a category of the explosion where the lava spreads rapidly at the on-the-surface eruption, individuals are most prevalent in sedimentary magmas, often occur spontaneously. Because of elevated heat, the fuels are withdrawn throughout magmas.However, in volcanic explosions, the magmas have been most aggressively ejected from the volcano whenever pressure at either the exhaust pipe is abruptly actually reduced.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.
