Growth and development is the process by which organisms uses energy to mature. Homeostasis maintains stable food to the organisms to keep them growing. Reproduction is the process of making the same organisms, homeostasis also help organisms to create new alike organisms. Homeostasis also changes through time cause your blood pressure can change in time. Homeostasis is also related to the organization of cells, because it keeps stable level in the cells.
Discuss the relationship between sexual selection and human reproductive behaviour. (8+16 Marks) Sexual selection is the process in which a species changes over time as a result of the passing on of the genes that make one individual more attractive than another. This could be anything from a long tails to bright colours. Charles Darwin believed that human reproductive behaviours have their origins in the past and exist because they ensured survival or reproductive advantages to us. There are two types of sexual selection.
This is what nature is all about, to be able to pass the ‘best’ genes to the next generation and that is most commonly the individuals within a population which are best adapted to the current environmental conditions and are ‘better’ to adjust to sudden environmental changes. It is important to understand that natural selection applies on the individuals of a population while evolution is a process between generations. The giraffe is a very good example to illustrate how natural selection works leading to evolution in the species. Within the entire giraffe population some
Therefore, the advantage of sexual reproduction is that it creates an individual with a greater chance of survival. Although, the disadvantage of sexual reproduction is that a lot of time is needed in finding a mate and going through courtship rituals. It is also important that the species attracts a mate in the correct season when mating is carried out for that
This increases the cell division in udders so more milk is produced. Survival and Response * Stimulus and response * Stimulus- detectable change in the internal or external environment of an organism that produce a response in the organism. * Because it can respond to the stimuli it increases the organisms’ chances of survival because it can detect and move away from harmful stimuli like predators and extremes of temperature or it can detect and move toward food; this aids survival. * These organisms have a greater chance of raising offspring and passing on their alleles to the next generation, so there is a selection pressure favouring organisms which respond to these stimuli. * The stimuli are detected by receptors- they transform the energy of a stimulus into a form of energy which can be used to produce a response.
Part I Essay Explain what is meant by the claim that ‘selection refers...to the survival of genes within the individual’ (page 121). Discuss whether this ‘selfish gene’ theory could explain the evolution of altruistic behaviour. Barrett’s claim that ‘selection refers not to the survival of the species but instead to the survival of the genes within the individual, as it is not the individual that persists over time but rather the genes ’ (as cited in Phoenix, 2007, p.121) can be explained with the selection processes, natural and sexual selection. The first part of this essay will explain these two processes and the main reason genes strive to survive within an individual, known as the ‘selfish gene’ theory. The second part of the essay will be used to discuss the evolution of altruistic behaviour and whether or not the ‘selfish gene’ theory could explain it .
Sustainable business spending would also increase rapidly because it is seen as a catalyst for more productive improvements which is a win for human beings, the company and our earth when reducing resources and lowering cost while still being sustainable. A company’s reputation is also a big factor as to why companies wanted to reduce environmental footprint as more investors are becoming increasingly interested in the environmental performance of a company where they put their money into. Also, because of customer awareness, large manufacturers and retailers are also using their buying power to push suppliers into more environmentally friendly practices. Green is the new ideal trend and it should be sticking around. Now it is much better to be knowledgable about your health as well as making overall healthier choices and it helps to know some of the companies we tend to rely on are also doing their part to become greener and meet the peoples needs.
Common Descent vs Intelligent Design Biology A Common descent and Intelligent design are two different types of hypothesis which both have enough beliefs and evidences to provide suitable explanation of the two theories. Common Decent is better known by biologist as “the fact of evolution” this is because of its well supported scientific information. Common decent is general descriptive theory which concerns the genetic origins of living organisms. This theory suggests that one organism began evolution, meaning that all living organism which are living today have evolved from one organism over a long period of time. Intelligent design contradicts the idea of the common descents.
Chapter 4 Evolution and Biodiversity Summary 1. Life emerged on the earth through two phases of development: a chemical evolution of the organic molecules, biopolymers, and systems of chemical reactions to form the first cells and the biological evolution from single-celled prokaryotic bacteria to single-celled eukaryotic creatures, and then to multicellular organisms. 2. Evolution is the change in a population’s genetic makeup over time. Evolution forces adaptations to changes in environmental conditions in a population.
CASE STUDY: NATURAL DESIGNS INC NATURAL DESIGNS INC ANTONIO HOGAN BA365 INTRO TO OPERATION MANAGEMENT GRANTHAM UNIVERSITY SEPTEMBER 30, 2013 CASE STUDY: NATURAL DESIGNS INC 1 What type of decisions must Jim McMaster make on a daily basis for Natural Designs to run smoothly? What kind o decisions must he make on a long-term basis? The long term decision for Jim McMaster is the structural decision making that can used for a long term basis, because it gives a detailed planning and a sustainable working capital. The following areas that can be improved on are: The facilities- buying more facilities will help the production procedures run smoothly on a daily basis. The technology- the use of new equipment or technology will increase the production and the quality of the products.
