occur with bad hay/grass. Those plants need good soil to be good which is something

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

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

Purpose: What is the purpose of this exercise? Are there any safety concerns associated with this exercise? If so, list what they are and what precautions should be taken. To understand the structure and function of multipolar neuron,unipolar and bipolar neurons. Also to identify the structures of a nerve. There are no safety concerns for this lab.

Make three exposures using given technical factors on a phantom knee in PA position . Include saline bags in exposures 1 and 2 to demonstrate patient soft tissue thickness.

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.

1. Both answers are correct. There are two different models for substrate binding: lock and key or induced fit. In the lock and key model, the active site of unbound enzymes fits perfectly with the complementary shape of its substrate. In the induced fit model, the enzyme changes shape to confirm to the substrate after binding.

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.

Hydrolysis of starch for fungal amylase Aspergillus Oryzae and bacterial amylase Bacillus Licheniformis at different temperatures.

The purpose of the “chi-square test” was to see if our data was in an acceptable range of a specific ratio listed above. The chi-square test took into account the expected deviations in the F2 offspring’s alleles.

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.

After my plant started to show growth, I had a problem with the water. The usual amount that I was giving it suddenly became too much. The water started rising above the soil and I would have to wait at least a day before I could give it a little bit more water. The temperature of the soil overall never changed. It always stayed the same. There were some day that it went down from 20 degrees to 15, but primarily the temperature was always 20 degrees. My plant was one of the last to grow and probably the smallest. The hours of sunlight exposure always remained constant. That is a factor I couldn’t change unless I put the plant in the shade. My plant got about 23 hours of sunlight each day. As mentioned before, the water situation was tricky, the first 2 weeks I gave the same amount of water but then it started becoming too much. Maybe it was because after my plant got all the nutrients from the water that it needed, it pushed out all the excess water. I started to put less water each day. When I thought the soil looked and felt really dry, I started putting 20 ml again, but then it rose above the water again. I didn’t really understand it, and I guess I still don’t. Overall, to answer the question, plants need correct measurement, water, space, air, and nutrients to grow. Plants also need attention and the proper care to
