I'm not very sure about this to be honest. I researched earlier and couldn't really find much besides reports talking about commensalist relationships with certain bacteria. Does anyone have any input in this? Generally, I think it's false, but I might be mistaken. Thanks in advance!

How will you prepare 5% of a solution in 40 mL of water NaCl? I'm quite familiar with how this goes: 5% Nacl is equal to 5g NaCl / 100g Solution based on % by mass formula. Since 100g is equal to 100 mL The answer here would be : 40 mL H2O x 5 g NaCl / 100 mL Soln = 2 g NaCl It was stated by one of the posts in quora that max saturation of NaCl at room temperature is 357 mg / ml Link: https://www.quora.com/How-will-you-prepare-5-of-a-solution-in-40-ml-of-water-NaCl I had a practical exam similar to this and I horribly failed because I thought the 15% NaCl which around 36 grams of NaCl (I thin…

Our delivery order placed on 25% on peak hours, 15% on normal hours and 60% on discount hours throughout the year. And our order placed on 50% on each company. So what is the formula to calculate the average delivery fees throughout the year? Thank you for advance.

I'm currently working on research proposals and I can't seem to wrap my head around the idea of what research design my topics falls to. Topics: Identifying zooplankton biodiversity and its effect on the quality of local fisheries of grouper fish - I was told by my tutor that it is a quasi-experimental design but I don't get how it is since there is no manipulation of the variables since I'm just identifying the zooplankton present in the fisheries and looking if the groupers are affected in terms of their physical attributes, etc. I think it is more of a correlational study? Still, I need a clearer viewpoint on this. Analysis of the presence of heavy m…

I have a piece of work to do where I must choose 1 out of 5 OMICS technology platforms (Genomics / Transcriptomics / Proteomics / Lipidomics / Metabolomics) and produce a presentation on a novel idea which utlises the technology to address the following problem: "A food company is experiencing issues with post-harvest quality of their products (fruit, vegetables and/or seafood). The issue arises from the accumulation of black/brown pigments, which causes gross discolouration and leads to the accumulation of wastes. Due to negative consumer perceptions, the affected products are rejected and devalued, thereby leading to significant financial losses. The food company a…

Hi everyone, I'd really appreciate it if I could have an answer for this question, I'm very stuck on it: Students carried out an investigation into the effects of osmosis on plant tissues, placing three sets of beetroot cylinders in three different sugar solutions for 30 minutes. One set had gained mass, another lost mass and the third set did not change. One student thought the last experiment hadn’t worked. Another disagreed. Explain the results in terms of osmosis in plant cells. (6 marks) Thank you!

Get your friends and family to play this simple little game that illustrates a key aspect of stochastic mathematics in application to finance. 1. Draw on a big sheet of paper a sequence of 30 squares and label them consecutively 0 (bankrupt), 1, 1, 2, 2, 3, 3, 4, . . . , 14, 14, 15 (millionairedom). Each of these squares represents one state in a 30-state Markov chain. Imagine each state represents the value of some asset such as the value of a small business that each player is managing. 2. Give each player a token and a six-sided die. 3. At the start place each token on the second “2”, the fifth state. Imagine this corresponds to the small business having an in…

An example of how probabilities are calculated in poker hand. Probability and Statistics with Applications: A Problem Solving Text By Leonard Asimow, Ph.D., ASA, Mark Maxwell, Ph.D., ASA You can ask me for more details about question, I won't paste them here, as it'd make the question too lengthy to view. What problem I'm trying to do? I am trying to find expected probability for random number independence testing aka poker test. We've 10,000 random numbers of five digit each. They're assumed to be independent. My calculations-: 1) Full house 10C1*9C1/10,000 =0.009 I'm…

Let a = any integer Why does a^(1) = a?

Let me begin by saying that I am doing a self-study of college algebra. I love mathematics. I regret not majoring in math back in my student days. With that said, I hope this forum will allow me to post questions that I get stuck with in my review of college algebra. Let a = any integer. Why does a^(0) = 1?

Im asked in a series of questions on the effects of Ph and Co2 concentration on haemoglobins affinity for oxygen which I am all over however, on the third question I am asked to discuss the effect of a certain mutation that I dont understand on the affinity. Glu B4 (23) alpha --> G ln is the mutation given. Any ideas?

Hello geniuses, this is Innocent Muggle who don't know about science and math. However, NEED ALL YOUR HELP!!! Here is question, 1. If battery capacity is 87kWh and max power is 430kW, can you calculate the weight? it's lithium ion battery pouch cell pack for car!

Hello all, I have a question on determine the transition probabilities for the following Markov chain. I’m not sure how to proceed. For the first part I crossed off the impossible probabilities but how do I calculate the others? Thank for your time

In a chess tournament, each participant plays with every other participant exactly once. Each participant gets 1 point for a winning a game, 0.5 points for a draw and no point for a loosing a game. At most, how many of the 40 participants can score 24 points or more? My attempt to answer this question: There will be [math]\binom{40}{2}=780[/math] games in this chess tournament. Now each player will play 39 game. The probability of winning a game is [math]\frac13[/math]. Probability of loosing a game is [math]\frac13[/math] and the probability of making a game draw is [math]\frac13[/math]. So, out of 780 games, 260 games will be won by some players, 260 games wil…

Calculate the line integral of the vecor field f(x,y,z) along the curve C [math]\left(\displaystyle\int\limits_C f \cdot dr\right) [/math] 1)f(x,y,z) = yzi + xzj + xyk; C : the polygonal path from (0,0,0) to (1,0,0) to ( 1,2,0). 2)f(x,y,z) = xyi + (z-x)j + 2yzk; C : the polygonal path from (0,0,0) to (1,0,0) to (1,2,0) to (1,2,-2). How can I use here Stokes theorem? My work to answer to both these questions is in progress. Any math help, clue, or even correct answers will be accepted.😇😀

I would like to ask what is the differences between Southern Blotting and RFLP? Thank you.

when you draw the displayed formula of a molecule, does it matter how you draw it as long as each atom makes the right number of bonds? for example, does it matter what the molecule C3H4O3 looks like as long as the carbon makes 4 bonds each, the oxygen 2 and the hydrogen 1?

how do i balance this half equation NO2- + H+--> NH2OH +H20 sorry nvm i worked it out

A student predicts that a steel ball dropped from rest from a height of 2 m will hit the floor after 0.63 seconds. In their calculation they used an approximate value for the acceleration due to gravity of g = 10 m/s2 . The accepted value for the acceleration due to gravity is g = 9.8 m/s2 . This means their calculated time will be: A. unaffected B. too long by about 1% C. too short by about 1% D. too long by about 0.2 seconds E. too short by about 0.2 seconds
