A food development company is interested in making on-the-go powder-based snacks in which consumers can "just add water" before eating. During market tests there are complaints that the powder does not dissolve well in water.If you were a food scientist, how might you modify the formula so that it will more easily dissolve in water? Provide your answer in 1-2 complete sentences.

Below is a list of physiological events involved in synaptic transmission. Using your knowledge from class, place the events in the correct order. A. Vesicles filled with neurotransmitter fuse with axon terminal end membrane B. An excitatory post synaptic potential results C. Ligand gated ion channels are stimulated to open D. Neurotransmitter binds to respective receptor E. Ca2 voltage gated channels are stimulated to open F. Action potential travels down the length of an axon G. Ca2 rushes in H. Neurotransmitter is released into synaptic cleft I. Na rushes in J. Action potential is generated at the axon hillock K. Ca2 interacts with docking proteins on secretory vesicle

In the tomato, red fruit (R) is completely dominant over green fruit (r) and yellow flowers (W) are completely dominant over white flowers (w). A cross is made between two true breeding plants, one has red fruit and yellow flowers and the other has green fruit and white flowers. The F1 generation has red fruit and yellow flowers. These F1 plants are test crossed to plants with green fruit and white flowers. The following results are obtained:333 red fruit, yellow flowers64 red fruit, white flowers58 yellow fruit, yellow flowers345 yellow fruit, white flowersTotal of 800Required:What are the phenotypes of the recombinant offspring of the F2 generation?

In order to establish the expiration date of perishable food, growth curve data must be collected. Once the microbial load is so high that it poses a hazard to human health, the food item is no longer considered safe (expired). Generally a load of x50,000 bacteria/gram is considered unsafe. Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto standard petri plates of nutrient agar. The following colony counts are measured. Based on this data and considering the information in the paragraph above regarding safe levels, Please choose the last possible day to enjoy the yogurt before there is a dangerous level of bacteria:Time (days) Micro Yo colony count #1 14 112 216 420 7a. 4b. 16c. 20d. 12

A boy falls ill with a new virus that nobody has described before (we'll call it Virus A). He contracted this virus from rat droppings near his home. After he falls ill, 80% of the members of his village become sick with the disease caused by Virus A. However, public health officials are able to confine the disease to one particular geographic region and to eliminate it completely after several months. Which of the following is true of Virus A? a) It caused a pandemic. b) It caused an epidemic/outbreak. c) It is a re-emerging virus. d) It is an emerging virus. e) It is a deliberately emerging virus. f) It is a zoonotic virus.

Several genes in humans in addition to the ABO gene (I) give rise to recognizable antigens on the surface of the red blood cells. The Rh marker is determined by positive (R) and negative alleles (r) of gene R, where R is completely dominant to r. The presence of M and N surface markers are controlled by two codominant alleles of gene L (LM and LN). For each mother-child pair, choose the father of the child from among the males in the right column. (Assume that all mothers and fathers are HH.)

Sally is a 41 year old female with a history of unsuccessful weight loss attempts. In the past, Sally has tried "almost every diet known to man" and now wants to lose "at least fifty pounds" and "stop fighting with myself". Sally lives alone, and works as an accountant. Her hobbies include reading, spending time with her cat, and shopping. She describes her life as "pretty isolated" and rates her happiness at a 4 out of 10. She explains that when trying to change her behavior, she usually "falls off the bandwagon after a few days", and describes herself as "stuck". She has no history of injuries or preclusions to exercise and has recently had a clean physical exam, with the exception of needing to lose weight. Describe what approach you would take with Sally to help her change her behavior?

Strains of petunias come in four pure-breeding colors: white, blue, red, and purple. White petunias are produced when plants synthesize no flower pigment. Blue petunias and red petunias are produced when plants synthesize blue or red pigment only. Purple petunias are produced in plants that synthesize both red and blue pigment.The mixture of red and blue makes purple. Flower-color pigments are synthesized by gene action in two separate pigment-producing biochemical pathways. Pathway I contains gene A that produces an enzyme to catalyze conversion of a colorless pigment designated White 1 to blue pigment. In Pathway II, the enzymatic product of gene B converts the colorless pigment designated White 2 to red pigment. The two genes assort independently.Part A: What are the possible genotype(s) for pure-breeding red petunias?AABBAABbAabbAaBbaaBBAAbbaabbaaBbAaBBPart B: What are the possible genotype(s) for true-breeding blue petunias?aaBBAABBAaBBaaBbAAbbAabbaabbAABbAaBb
