Genetically modified organisms (GMOs) are created by inserting one or more genes into an organism's genome. As you know, each gene codes for a polypeptide or protein, so by inserting a new gene we can get organisms to produce a new protein. A researcher would like to make a genetically modified cow that has more of a specific type of protein called mooglobin. What is his most likely approach?

Question 35 options:

A)    Insert a gene in the cow's genome that codes for an enzyme involved in the decomposition of mooglobin

B)    Insert a gene in the cow's chloroplast that codes for a protein involved in mooglobin synthesis

C)    Insert a gene in the cow's genome that codes for a carbohydrate that acts as an enzyme in mooglobin synthesis

D)    Inject the cow with purified mooglobin protein daily for several weeks

E)    Insert a gene in the cow's genome that codes for a protein that acts as a catalyst in mooglobin synthesis.

Question 42 (15 points)

You have read that inorganic fertilizers contribute to water pollution and would like to make a switch from inorganic fertilizers to organic compost in your vegetable garden. A friend graciously gives you a truck load of his compost. As a good researcher and critical thinker you are not convinced that organic compost will yield the same results as the inorganic fertilizer you have used for years with good results. To draw your own conclusion based on scientific evidence you decide to conduct an experiment in your garden. State a good hypothesis, design an experiment (include test subjects, sample size, control(s), dependent and independent variables, type of data collected) and hypothetical results/conclusion. Does your conclusion support the hypothesis?

Question 44 (15 points)

You scoop up a water sample from a local pond nearby, because you are curious about the possible microbes that might live there. After looking at several slides that held drops of the sample, you noticed two different kinds of cells: One kind was very small and had no separate internal structures; the other kind was much larger, and it contained several kinds of internal structures that were physically different from each other. Please name each cell and briefly describe their overall similarities and differences.

A.    It loses a phosphate group, releasing energy in the process

B.    It adds a phosphate group, releasing energy in the process

C.    It releases electrons, which are a source of energy

D.    It releases protons, which are used in the mitochondria to create energy

E.    It shuttles electrons across the mitochoindrial membrane to create potential energy

Explanation / Answer

31. A It loses a phosphate group, releasing energy in the process

32 .(D) Water is used during photosynthesis to capture the electrons released from excited chlorophyll pigments is False because water acts as a donor of electrons.

33. In Central DOgma DNA is transcribed into RNA and RNA is translated into Proteins.

34. (d)    Daughter cells from meiosis II have 46 chromosomes is Flase they have 23 chromosomes

35. E)    Insert a gene in the cow's genome that codes for a protein that acts as a catalyst in mooglobin synthesis

36. (D) Carbohydrate is the primary energy source for organisms.

37. (D) They are not amde of cells

38 . Population --> Community --> Ecosystem

39 . Potential energy

40 . (C) Amino acids make up proteins.

41. Bioethical concerns include that this data can be used for other purposes and creating genetically modified organisms which is not approved by the government. DNA is highly susceptible to getting ruined .

42. start by creating two separate gardens,one which uses inorganic fertilizer and another which would use organic fertilizer. Create two separate gardens containing the same plantsand test whether or not the garden with the organic fertilizer responded in the same way as the garden without the inorganic fertilizer. Hypothesize that the garden with the organic fertilizer wouldn’t grow as good as the garden with the inorganic fertilizer hypothetical conclusion would be that although not as good as the inorganic fertilizer the organic fertilizer is good and organic fertilizer is a viable replacement for inorganic fertilizer

43. I live in a place which is close to the Desert biome/ecosystem . Mainly shrubs are found within the ecosystem . Also there are Date Palm trees and Eucalyptus trees around there and native species include Camels , Lizards , Chameleons , Vultures etc. Due to movement of people many animals such as Camels are used by the people for their purposes which affect hteir growth and reproduction.

44. First cell resembles an Algae which consists of a regular shape and not many internal structures. The other cell could be an Animal cell which has irregular shape and larger than algae . SImilarities would be presence of Mitochondria , ER , Cytoplasm etc. Difference is the shape of the two cells.
