Describe how oxygen is transported in blood, and explain how temperature, pH, BPG, and affect oxygen loading and unloading.
Solution :
The flow of oxygen in the blood is been transported by two ways :
1. in plasma 1.5%
2. bound to hemoglobin 98.5%
As the oxygen loads in the body, affinity of the Hb makes the oxygen loading very efficient in the blood. The Hb molecule gets saturated when all the 4 hemes are oxygen binded.
The decreased pH weakens the hemoglobin oxygen binding in the tissues.
Higher temperatures in the oxygen means a lower affinity and thus more oxygen is released and so the oxygen unloads.
Increase in the temperature, the BPG and the modification of the structure in the hemoglobin decreases the affinity for the oxygen and further enhances the unloading of the oxygen in the blood.

Group of answer choices
perfusion

ventilation
diffusion
Answer:
ventilation
Explanation:
Breathing, also known as ventilation, is the process of moving air or water in order to facilitate the gas exchange between the external and internal (body) environment, mostly to eliminate carbon dioxide (CO2) and bring in oxygen (O2). For example, fish are aquatic animals that need to run water over their gills to get the O2 that they need to survive (gills are organs that create a large surface area for ventilation). Moreover, insects ventilate their tracheal system to get O2. Finally, terrestrial vertebrates (i.e., amphibians, reptiles, birds, and mammals) use organs called lungs to exchange O2 and CO2 between their cells and the external environment.

A suspension of yeast cells is being grown under anaerobic conditions such that glucose is degraded to ethanol and carbon dioxide. To follow this process by monitoring the release of CO214, at which positions in the glucose molecule would the C14 label need to be incorporated
Answer:
carbons 3 and 4
Explanation:
Alcoholic fermentation is an anaerobic (non-oxygen-requiring) pathway capable of converting one mole of glucose (C6H12O6) into two moles of ethanol (C2H5OH) and two moles of carbon dioxide (CO2), producing during this process two moles of ATP. The overall chemical reaction is as follow: C6H12O6 (glucose) >> 2 C2H5OH (ethanol) + 2 CO2. During this process (fermentation), energy is obtained from the glycolysis process by which each glucose molecule is broken down into two pyruvate molecules (2 CH3COCOO−). Pyruvic acid is an organic acid that ionizes to produce a hydrogen ion and a molecule of pyruvate. Subsequently, this pyruvate is then converted into ethanol and CO2, generating NAD+, i.e., the oxidized form of nicotinamide adenine dinucleotide or NAD, which is required for glycolysis (and therefore to produce ATP). Moreover, dismutation refers to the redox reaction by which one compound with an intermediate oxidation state converts into two compounds. In consequence, the CO2 generated during fermentation arises from the dismutation of pyruvic acid. During this process, the major source of CO2 is carbon 3 (C3) and carbon 4 (C4) of the glucose as a result of the dismutation of pyruvate, and thereby these positions in the glucose molecule would the C14 label need to be incorporated.

Albinism is a recessive trait where an individual does not produce the pigment melanin. A man and woman who both produce melanin have one child out of three who has albinism. What are the genotypes of the man and woman
Albinism is a recessive trait where an individual does not produce the pigment melanin. Albinism is an autosomal disease where the gene which is expressed here is having albinism which is the cause of heterozygous condition.
What is the heterozygous ?
Heterozygous is the condition where the genes in the alleles are different to each other where one has a dominant character and one has a recessive character. The genotypes of the woman and man decide the genotype of the offspring.
The genotypes of the man and woman is heterozygous where the dominant once out of 3 will have the dominant traits for the albinism. The condition will have to be heterozygous as in the Ia Ii gene where the gene for the albinism will be i gene.
The same genotype for the male where the Ib i gene in which i i the albinism carrying gene here the ii condition of the gene will express the albinism.

What is the role of DNA polymerase enzymes in replication?
(A) unzipping the double helix by breaking down the hydrogen bonds
(B) adding the free nucleotides to the complementary strand of DNA
(C) splitting the DNA molecule
(D)connecting the fragments on the lagging strand of DNA
Answer:
A
Explanation:
the function of DNA polymerase is to unzip the double helix structure of DNA by breaking down the weak hydrogen bond
Answer:
(B) adding the free nucleotides to the complementary strand of DNA
Explanation:
A DNA polymerase is an enzyme capable of creating new DNA molecules by sequentially adding nucleotides to the three prime (3')-end of a DNA strand. A DNA strand is a polynucleotide chain composed of a linear series of nucleotides, each consisting of a deoxyribose sugar, and phosphate, and a base (i.e., thymine, guanine, cytosine and adenine). Before a cell starts to divide, it needs first to replicate its genetic material by using DNA polymerases that duplicate the cell's DNA during the interphase (S phase). During this process (DNA replication), an enzyme known as helicase unwinds the DNA molecule, which is made up of two antiparallel strands oriented in opposite 3′-5′ directions to each other. Subsequently, each strand is used as a template for its replication through DNA polymerases that can add nucleotides (one at time) to an existing short fragment of RNA, i.e., the primer sequence, which is paired with the template DNA strand.

In working with Drosphilia it is common to use a balancer stock to maintain mutations of interest. The balancer chromosomes are generally carrying multiple inversions on them. What effect would the inversions have on meiosis
Answer:
Fusion or pairing does not occur.
Explanation:
Inversions mutation leads to lowered fertility due to production of unbalanced gametes in the meiosis cell division. Chromosome inversions have no effect on mitosis, but they has affect meiosis because inversions changes the gametes which is only present in meiosis. If an inversion present is in the heterozygous condition, pairing of chromosomes cannot occur in a simple linear fashion due to change of sizes. But if the inverted chromosome segment has the proper size so it can paired with each other.
