If feeding efficiency and reproduction have a direct correlation, and a population started with equal proportions of individuals with each of three feeding types, metal spoon, metal knife, and plastic fork, the frequency of the population with metal spoons as their feeding structure will increase in the next generation. While the frequency of metal knifes and plastic forks will decrease. Furthermore, since the organisms with the metal spoon feeding structure have a higher fitness level, this population will evolve by natural selection to a point where the metal spoon phenotype will be in abundant. While the organisms with metal knifes and plastic forks phenotypes will decrease in frequency due to the lack of reproduction. Eventually, if this population persist overtime, most of the organisms, if not all, will have the metal spoon phenotype, while very few, if not any, will have the metal knife or the plastic fork phenotype.

Introduction: The biological membranes are composed of phospholipid bilayers, each phospholipid with hydrophilic heads and hydrophobic tails, and proteins. This arrangement of the proteins and lipids produces a selectively permeable membrane. Many kinds of molecules surround or are contained within

Observation: no bugs were found except small, black, gnats were all close to the ground.

I learned that anaerobic is an organism or tissue that is living in the absence of air or oxygen while aerobic is involves the organism or tissue receiving and requiring air. Furthermore I learned about the anaerobic cellular respiration that uses an electron acceptor rather than oxygen to complete metabolism using electron transport-based chemiosmosis. Also in this reading I learned about fermentation which is an anaerobic process in which energy can be released from glucose even though oxygen is not available.

The oxidation number of an atom of any free element is ZERO. Means to say there is only one kind of atom present, no charge.

An association between enzyme production, gene copy number, and gene evolution was explored by conducting analysis of the salivary amylase enzyme, AMY1A gene copy number, and the ancestral starch consumption in Homo Sapiens (Tracey 2017, p.22). It was hypothesized that the relative amount of starch consumption was very high for my personal ancestral diet, thus my AMY1 diploid gene copy number in my genome and salivary amylase concentration would be significantly higher than the population mean. With a population of 28 subjects (n=28), individual saliva samples were collected and compared to a calibration curve to determine the approximate amylase concentration by analyzing absorbance values. Individual samples of buccal cheek cells were

Ps: the iodine was already really dark so it was very hard to see much difference between the control and the others.

The major storage polysaccharide in plants is starch. These molecules would be found in abundance in the stroma in the plant tubers where it is found as granules. Glucose is stored mainly in the form of starch granules, in plastids like chloroplasts and amyloplasts. Plant starch starts out as glucose, but glucose is very hard for plants to store, so it is converted to starch through polymerization. Amyoplasts turn the glucose into starch and move it to the stroma, and in tubers the stroma is a place to store the food (starch), and when plants need the energy in the starch, it converts the starch back into glucose.

The purpose of this experiment was we were trying to see if the number of arthropods would be significantly different in sparse and dense areas of the woods. Ms.Ehnert provided us with the design of a trap to set up in the woods so we could more actually count the amount and types of bugs that we find. The trap was a cup filled with anti-freeze that we put in the ground and then covered it with a paper plait, but raised it so bugs could get in and bigger animals couldn’t. We waited for a week to collect the results and then counted all of them and sorted them. My hypothesis was based off of common sense, the simple assumption that less trees equals less arthropods and more trees equals more arthropods. I knew that living things need a habitat

2. (5 pts) List and explain the names and affiliations of the various characters/stakeholders in this story – I’m looking for us to use the story to map out the complexities that are generally associated with solving public health puzzles – the stakeholders you list and explain here should apply to many of the cases we consider going forward.

Spirit stumbled across rocks that pointed to an earlier, unrulier Mars that was marked by impacts, explosive volcanism and subsurface water [source: NASA Mars]. "Water is key because almost everywhere we find water on Earth we find life," NASA's Web site. However, we are still unsure life existed on Mars.

Liquid water is the most important factor for life, as we know it. Water is abundant in the galaxy, it is found in cold dense molecular stars as well as hot stellar atmospheres. Liquid water exists at a large range of pressures and temperature.

This suggests that the orange colony was due to contamination, indicating that there was an error in the experimental procedure used. The team results indicate no protein-protein interaction between the strain Bub1B (328-1052) and any of the four potential interactors. These results differ from those produced by the class for the strain Bub1B (328-1052), which instead indicate protein-protein interactions occurring between the Bub1B protein and BUB3 as well as Bub1B and Ppp2rc, for the strain Bub1B (328-1052).

surface of Mars. These were disproved as tricks of the eye. Spacecraft in the 1960’s

The first and arguably the most non-negotiable condition needed for life is liquid water. This is because every form of life on Earth requires liquid water and if we are going to find something identical to life on Earth, we will look for places that have similar necessities for life. Liquid water is a necessity because science has not discovered an organism that has proven water is dispensable. This compound has not only started life on Earth but also has assisted in advancing our civilization. Without it, there would be no keeping ourselves or our food clean, supplying a method of travel, or a power source.
