To determine: The pattern of changes one can predict on the basis of life history theory.
Introduction: Life history theory can be defined as a branch of evolutionary biology and ecology that aims to explain and predict the recognizable patterns in the life histories of organisms. It is an analytical framework by which different strategies adapted by living organisms can be precisely studied.

Explanation of Solution
The life history theory is related to the processes which occur in the life of an individual, such as growth, reproduction, and survival of organisms. On the basis of life history theory, one could predict the pattern of changes in the case of female parasitoid wasps. This insect search for insect hosts for laying eggs and often does discrimination among more or less suitable host. The life history theory predicts that females which are older should not be choosy regarding the selection of their host in which they have to lay eggs.
When the time of reproduction would be running out, female wasps should attempt to have multiple numbers of offsprings. It should be done for increasing the survival rates of some offspring, rather wait for a more or less suitable host.
To determine: The prediction of life history theory about animal behavior.
Introduction: Life history theory can be defined as a branch of evolutionary biology and ecology that aims to explain and predict the recognizable patterns in the life histories of organisms. It is an analytical framework by which different strategies adapted by living organisms can be precisely studied.

Explanation of Solution
Life history theory suggests that there is a risk of death of animals in the absence of reproduction process. Hence, optimality theory is very essential for the adaptations which are associated with the evolution of life on the Earth. Therefore, life history theory is very essential for studying animal behavior.

- 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. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobinarrow_forwardWith reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra?

- 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.
