Virtual Laboratory Activity - BIOL 1121 - Unit 3

Data Collection and Result

While you are working on this virtual lab activity, please record your data in the tables below. 1. What is the difference between a. and a. Data Collection Table A. First Set – Presence of Green and Blue leakage channel No. Solution Movement Across Membrane 1. Green Particles 2 - Particles 2. Blue Particles 1 particle Overall observation: I observed that, the green particles were the first to cross. Also, both particles crossed and were able to turn back. There were movements of both green and blue particles.

B. Second Set – One green and one blue gated channel No. Solution: Movement Across Membrane when the channels are closed; Movement Across Membrane when the …show more content…
What is the difference between a'smart' and a'smart'? Questions Based on your observations and from your readings of the chapter, answer the following questions: 1. What type of biomolecules are receptors? They are proteins inside a cell or its surface that receive a signal. 2. What is the difference between a'smart' and a'smart'? Once triggered, how is the signal processed inside the cell? It triggers a series of steps that decodes a message through a transduction pathway. 3. What is the difference between a'smart' and a'smart'? What are the most common receptors for growth factors? The most common receptors for growth factors are receptor tyrosine kinases. 4. What is the difference between a.. What types of signalling proteins are common in animals but absent from plant cells, and vice versa? Signalling proteins common in animals but absent in plant cells are hormones, and cytokines whereas those common in plants but absent in animals are phytochromes, and receptor-like kinases. Clark et al., 2023. 5. How does signalling by hydrophobic molecules like steroid hormones differ from signalling by peptide hormones? Hydrophilic elements are usually charged or polar, while hydrophobic elements are nonpolar. 6. What is the difference between a'smart' and a'smart'? NO (nitric oxide) does not have a specific cellular receptor. How, then, does it act as a signaling molecule? It acts through a process known as diffusion-based signalling. 7. What is the difference between a'smart' and a'smart'? Discuss the validity of the following proposition. A signalling molecule (hormone, growth factor, or neurotransmitter) elicits identical responses in different types of target cells if they contain identical receptors. Cite an example of a. The proposition asserts that a signalling molecule will produce identical responses in diverse kinds of target cells if they encompass identical receptors. An example that supports this proposition is the hormone insulin, which is formed by the

Station 1A: Reflection (Mirrors) 1.This station shows reflection because it shows how the laser reflects off the mirrors. 2.This station does not have energy that is being absorbed. The energy in this station is not being absorbed it is being reflected off the mirror. 3.The shapes that were in this station were triangles because the laser reflected off the mirrors in a triangle shape 4.Two other examples of reflection is when you can see yourself in a bubble and also when light reflects of…

1.) Sticky ends are sites seen on single-stranded DNA or RNA molecules, having a nucleotide base sequence complementary to that of another strand. These are created when restriction endonucleases are used to unevenly cut, or cleave DNA at a specific sequence, allowing for the two strands to be connected by base pairing. These structures are produced in the laboratory with the use of restriction enzymes for cloning purposes. Scientists can choose from several places to cut the genetic sequence with…

In Lab 9, we looked at three kingdoms of autotrophic protists: Stramenophiles (brown algae and diatoms); Rhodophyta (the red algae); and Chlorophyta (green algae). Autotrophic protists are at the base of the aquatic food chain, and they range vastly in size, color, movement, and life cycle. It is interesting how diatoms produce nearly fifty percent of the earth's oxygen. In addition to the main lab activity, we compared two SF bay water samples, one of which contained a small amount of fertilizer…

1. Parameters that define substrate characteristics: Substrate characteristics parameters basically include the attributes that define the substrate, such as the elasticity of the substrate used, Poisson's ration of the substrate, thickness of the substrate, diameter of the fluorescent beads embedded into the substrates, etc. a.

exception was the length at 1 second. This length was not even close to the absolute error. The suspected reason for this is because, in the beginning, our group was not properly swinging the pendulum at the correct time. When comparing the increasing absolute error and the relative error values, I could not identify any significant pattern. The found values were sometimes higher and sometimes lower. No pattern or meaningful change was identified in our data. In Graph 1 there is an obvious observation…

If-then rules are developed based on input Fuzzy variables shown in Figures 1, 2, and 3, as shown in Table 1. A selection chance is considered for each of network nodes based on rules presented in Table 1. In this section, 9 levels are considered for each node's chance (i.e. very weak, weak, slightly weak, below average, average, above average, slightly strong, strong, very strong). Probability value for each level is determined based on Table 2. The higher the probability value is, the higher is…

Subnet Mask : To create the subnet mask, first remember that the purpose of the subnet mask is to separate the (32 bit) ip address into the network prefix and the host number. If a bit in the subnet mask is 1, the corresponding bit in the IP address is part of the network address; if the bit in the subnet mask is 0, the corresponding bit in the IP address is part of the host address. First depict the ip address in binary. Take 192.168.100.0 and convert to binary: ip address: 11000000…

Project 1: Lab Report Frank Johnson CHM2045L Section 001 June 5, 2018 Introduction: We discover some elements in nature that are unknown and it’s difficult to know what elements are in these compounds. We can take a random substance that is unknown from nature and figure out what it is composed of by running simple lab tests. A real-world example of this would be how doctors examine a patient’s blood to see if they have overdosed off of drugs. By using the procedures in this project 1 lab, we can…
