Answer to Problem 1FTB
Introduction:
Population comprises all the organisms of the same group or species, living in a specific geographical area. The adaptation process provides the support to the organism to live in that particular environment and thus helps in their reproduction. Organisms involved in a population of a specific area are able to interbreed, thereby supports the process of sexual reproduction.
Explanation of Solution
Species: The largest group of organisms which have the potential to interbreed with the individual of the same group within a geographical area, is known as species. The niche of these individuals is known as their habitat.
Population: The individuals of the same group or species, that are capable to interbreed in a particular geographical area, are known as population. They are thus able to exchange their gametes in order to produce fertile offsprings. The main attribute of a population is recognized by the phenotypic characters of the individuals who are involved in it. These phenotypic characters are governed by alleles. Any change in the allelic frequencies over the years results in the evolution of the individual. Thus the population evolves independently.
Reproductive isolation: The species that are able to breed in their groups in a particular given area are reproductively isolated. This mechanism ensures that an offspring produced from different species of the different geographical area should be infertile in nature. This is a biological phenomenon, which results in speciation.
A sexual reproduction: This is a type of reproduction in which off springs arise from a single parent. This process does not involve the fusion of gametes, thus the information inherited by the offspring is from only one parent. This type of reproduction does not establish genetic diversity into the environment, thus no biological concept can be applied to them.
A species is a group of the population that evolves independently. The biological species concept identifies species on the basis of their reproductive isolation. The biological concept cannot be applied to species that reproduce asexually.

- Design a grafting experiment to determine if limb mesoderm determines forelimb / hindlimb identity. Include the experiment, a control, and an interpretation in your answer.arrow_forwardThe Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange. The genotypes and associated phenotypes for some of these flowers are as follows: aabb: yellow AABB, AABb, AaBb, and AaBB: red AAbb and Aabb: orange aaBB: yellow aaBb: ? Based on this information, what would the phenotype of a Snapdragon with the genotype aaBb be and why? Question 21 options: orange because A is epistatic to B yellow because A is epistatic to B red because B is epistatic to A orange because B is epistatic to A red because A is epistatic to B yellow because B is epistatic to Aarrow_forwardA sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.arrow_forward

The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5.

- Which ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits. The subunits are joined by disulphide bonds. Each subunit covalently binds a haem group. Conformational change in one subunit can be transmitted to another. There are many variant ("mutant") forms of haemoglobin that are not harmful.arrow_forwardWhich ONE of the following is FALSE regarding haemoglobin? It has two alpha subunits and two beta subunits.
