Identify the incorrect statement regarding the fundamental causes of edema. Multiple Choice Capillary reabsorption does not depend on oncotic pressure. A deficiency of albumin (hypoproteinemia) produces edema by reducing the reabsorption of tissue fluid. Kidney failure leads to water retention and hypertension, thus raising capillary blood pressure and filtration rate. Obstruction of lymphatic vessels can interfere with fluid drainage and lead to the accumulation of tissue fluid distal to the obstruction. Since albumin is produced by the liver, liver diseases, such as cirrhosis, tend to lead to hypoproteinemia and edema.
Answer:
Capillary reabsorption does not depend on oncotic pressure
Explanation:
Edema refers to the swelling caused by the fluids trapped in the body's tissues, which swell from injury and/or inflammation. Edema can be associated with the decrease in plasma oncotic pressure, i.e., osmotic pressure exerted by proteins (especially albumin) in the blood vessel's plasma, the increase in hydrostatic pressure, or the increase in the capillary permeability. Moreover, capillary reabsorption refers to the movement of fluid from interstitial space to the capillaries, which is driven by the blood colloidal osmotic pressure. Lymphatic obstruction, i.e., the blockage of the lymph vessels that drain fluids from tissues, may cause edema in the part that is drained by the affected vessels (it is known as lymphedema). Moreover, liver/kidney failure may lead to edema by decreasing albumin and oncotic pressure. When plasma albumin levels drop because of liver diseases, the colloid osmotic pressure also decreases. In consequence, liver diseases, including stage 3 cirrhosis, lead to the development of swelling in the abdomen, thereby leading to edema.

A study is done on a group of families in Sweden that are segregating a genetic disorder. A statistical estimate of whether two genes, or a gene and a disease gene, are likely to be located near each other on a chromosome (called Lod-score analysis) indicates that the gene involved in the disorder shows a strong likelihood of linkage with a particular DNA marker locus. However, a second study done in Italy with other families segregating the same genetic disorder results in lod-score values that strongly indicate the lack of linkage between the gene and the same DNA marker locus. Assuming that both studies were performed appropriately, what is the most likely explanation for the different outcomes
Answer:
This disorder is caused by mutations in either of two different genes; one of these genes is linked to the DNA marker locus and the other gene is not.
Explanation:
A gene marker (also known as a molecular marker) is defined as a particular DNA sequence that has a specific physical location on a given chromosome. The gene markers are always physically linked with genes of interest, thereby they are useful for identifying patients affected by a given disease and/or a particular phenotypic trait. In this case, in the first study, genetic variation of the marker has been shown to be useful to map one locus that is associated with the disease phenotype. However, in the second study, a second locus that is not linked to the marker can segregate independently, thereby showing different results from the first study (in this case, it is imperative to develop a new genetic linkage analysis to discover genetic markers linked to the second gene, which is also responsible for the disease phenotype).

What cycle of replication is used by the common cold virus?
A: Dormant cycle
B: Replication cycle
C: Lytic cycle
D: Lysogenic cycle
Answer:
C
Explanation:
The lytic cycle involves the reproduction of viruses using a host cell to manufacture more viruses; the viruses then burst out of the cell. The lysogenic cycle involves the incorporation of the viral genome into the host cell genome, infecting it from within.
The common cold virus is replicated using the lytic cycle, by introducing its genome into the host and using its cellular machinery, hence option c is correct.
How common cold virus replicate?The common cold virus is replicated by using the lytic cycle, in which the virus introduces its genome into the host genome and uses all the replicating machinery of the virus.
The lysogenic cycle is different from the lytic cycle in which the viral genome replicates on its own and does not integrate its genome into the host genome.
After replicating its genome with the host genome, the viral genome is excised from the host genome and assembled into new viral particles for infecting other host cells. The new viral particle lysed the host cell and spread to other cells.
Therefore lytic cycle is used by the common cold virus, hence option c is correct.

How is an RNA molecule different from a DNA molecule?
RNA is single stranded and composed of nitrogenous bases, a phosphate group, and a pentose sugar.
RNA is single stranded and composed of nitrogenous bases, a phosphate group, and a tetrose sugar.
RNA is a double-stranded helix and composed of nitrogenous bases, a fatty acid, and a pentose sugar.
RNA is single stranded and composed of nitrogenous bases, an amino acid, and a hexose sugar.
Answer:
RNA is single-stranded and composed of nitrogenous bases, a phosphate group, and pentose sugar.
Explanation:
RNA is different from DNA because instead of having two matching bases; it is only made of one strand of nitrogenous bases. These bases are attached to the phosphate, which holds the whole strand of RNA together. The sugar acts as a carrier for the bases. The sugar in RNA is known as ribose and contains 5 carbon molecules. This is why it is called pentose sugar.

Answer:
7. Substitution mutation
8. Substitution mutation
9. Frameshift mutation
Explanation:
A substitution mutation is any kind of mutation that involves replacement of one or more nucleotide base by another in a sequence.
A frameshift mutation, on the other hand, is a mutation that changes the reading frame of the sequence. Two types of mutations cause frameshift viz: insertion and deletion mutation.
In the following sequences, mutation has occured as follows:
7. UGU-CCG-GAA-CGA to UGC-CGG-GAA-CGA - Substitution mutation has occured because nucleotides C and G has replaced C and U in the first and second codons respectively.
8. GAA-CGU-AGC-GGU to GAU-CGU-AGC-GGU- A substitution mutation because nucleotide U has replaced A in the first codon.
9. UGU-UUC-CCU-UAA to UGU-UCC-CUU-AA - A frameshift mutation because nucleotide U has been removed from the second codon, hence, causing a change in the reading frame.

Chemosynthesis _______. Question 11 options: uses energy derived from hydrocarbons and hydrogen sulfide in place of solar energy produces carbohydrates and sugars occurs around hydrothermal vents near the oceanic ridge system Both a and c are correct. All of the above are correct.
Answer:
The answer is all of the above are correct.
Explanation:
Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food. All chemosynthetic organisms use energy released by chemical reactions to make a sugar, but different species use different pathways. For example, at hydrothermal vents, bacteria oxidize hydrogen sulfide and add carbon dioxide and oxygen to produce sugar, sulfur, and water:
CO2 + 4H2S + O2 ⇒ CH20 + 4S + 3H2O.
Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight. Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent. During chemosynthesis, bacteria living on the seafloor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide (dissolved in seawater). Pure sulfur and sulfur compounds are produced as by-products.

Which of the following is a normal process of photosynthesis that could not occur if all reaction centers were inactivated by a toxin?
A. donation of excited electrons by chlorophyll a to a primary electron acceptor
B. absorption of photons by chlorophyll b
C. absorption of photons by carotenoids
D. donation of excited electrons by chlorophyll b to a primary electron acceptor
Answer:
A. donation of excited electrons by chlorophyll a to a primary electron acceptor
Explanation:
Photosystems are structures located at the thylakoid membrane that act to harvest energy light in order to convert it into chemical energy. Each photosystem is composed of a light-harvesting complex and a core complex, which in turn is composed of a reaction center. The photosynthetic reaction centers are multi-protein complexes that use light energy to catalyze the electron transfer across the chloroplast thylakoid membrane against a thermodynamic gradient. Moreover, antenna pigments are pigments that capture the energy from photons in order to transfer energy to other pigments in the photosystem (e.g., chlorophyll B and carotenes are antenna pigments, whereas chlorophyll A is the core pigment). Light energy absorbed by antenna pigments in the photosystems is transferred to the reaction center chlorophyll A molecules, thereby exiting electrons in the reaction center. A reaction center consists of two chlorophyll A molecules, which donate electrons to the primary electron acceptor.
(ii) Fish use their gills as a gas exchange surface.

Since the reason of the large surface area of the gills, gas exchange in fish is very efficient. the blood capillaries' large surface area in each gill filament The outer layer of the gill filaments as well as the capillary walls are only one cell thick due to the short distance required for diffusion.
What are gills?A gill is a respiratory organ found in many aquatic organisms that allows them to extract dissolved oxygen from water and expel carbon dioxide.
Some species' gills, such as hermit crabs, have adapted to allow them to breathe on land as long as they are kept moist.
Water runs over the gills as the fish opens its mouth, and blood in the capillaries picks up oxygen dissolved in the water. The blood then circulates through the fish's body to deliver oxygen, just as it does in humans.
Fish have gills, which allow them to "breathe" oxygen from the water. Water enters the mouth, travels through the gills, and exits the body via a special opening.
As the water passes over them, the gills absorb oxygen from it. The body of a fish is stream-lined.
Thus, these are the ways, in which fish gills are adapted for efficient gas exchange.
