Ted talk: To overcome challenges, stop comparing yourself to others by Dean Furness 1. The main focus of the path-goal theory is motivation, what the followers need to complete the task. 2. How does the Ted Talk you just watched relate to motivation, and connecting individuals to achieve their goal they are setting? 3. As a leader, if individuals lack the motivation to complete their task how can you encourage them to accomplish the task at hand?3. 4. Have you experienced a situation where you felt your manager had placed you in an ingroup or outgroup? If so, how did you handle that situation? 5. Do you know an individual who holds the traits of a transformational leader? If so, what does that individual do that makes them a transformational leader..

Suppose that you wanted to create a crop plant that has cabbage leaves and radish roots, so that no part of the plant would go to waste. You crossed cabbage and radish to produce radicole plant hybrids. However, radicole plant hybrids are sterile and cannot produce viable offspring through sexual reproduction. Why is the first-generation hybrid typically sterile? a. Due to an imbalance of the chromosomes that prevents even pairing of the chromosomes during meiosis b. Due to the non-homologous chromosomes that prevent even pairing of the chromosomes during mitosis c. Due to a spontaneous duplication of the chromosomes that occur naturally You would like the hybrid radicole plant to continue sexual reproduction, so that you can get continuous yield. Is it possible to generate fertile second-generation hybrids? How? a. Its not possible b. By inducing a chromosomal duplication event in the first-generation hybrid c. By crossing two first-generation radicole hybrids d. By crossing radicole hybrids with cabbage or radish"].

t has been said that beauty is in the eye of the beholder. I may think a property is beautiful and the lender may view the property as a potential liability and future disaster. After providing the lender with an appraisal from my brother in law's company they are still unwilling to offer a loan. How might a buyer convince the lender that a property is worthy of a loan and the risk involved for the lender? What creative ways thinking outside of the box could I use as borrower to secure the financing.

Susan Strickler, a bioengineer and founder of XL Biosystems Inc, together with two other co- founders invested a total of $60,000 from personal funds as seed financing when they launched their new venture in March 2022. Susan, who had the initial idea for XL and had invested the greatest amount of sweat equity to date, invested $20,000 and received 50,000 shares of XL common stock in return. The other two co-founders also invested $20,000 each and each received 25,000 shares. No other shares have been issued since. When the company was launched in March 2022, the founders also secured the backing of Meg Hopkins, a local angel investor with substantial and relevant experience in security systems. Meg invested $500,000 in XL with a post-money SAFE. Terms of the SAFE included: (i) a conversion discount of 20% tied to the Series A share price; (ii) a $1,000,000 minimum future financing for conversion of the SAFE; (iii) a post-money valuation cap of $5,000,000 for the SAFE; and, (iv) if XL is acquired prior to a Series A financing, Meg would receive 150% of the SAFEs principal investment amount. As of today (i.e., March 2023) they have successfully developed a working prototype of their revolutionary new system-on-a-chip for detecting hazardous biological agents using micro- electro-mechanical systems (MEMS) technology. Their MEMS biochip system has already attracted favorable attention from a number of security systems companies. Carl Montgomery, a local angel investor with substantial experience in security technologies, has been introduced to Susan by a trusted acquaintance and is considering an investment in XL. Carl has reviewed XLs business plan and has conducted enough due diligence to be comfortable with an investment in the company. XLs business plan calls for two new rounds of financing. Carl is planning to be the Series A investor, which is planned for March 2023 in the amount of $1,500,000. These funds will be used primarily for hiring development engineers, for further product development and market research, and for beta testing the prototype. The Series B financing is planned for March 2025 in the amount of $11,000,000 primarily for hiring production engineers and marketing personnel, for initiating marketing and distribution activities, and for launching production. Financial projections in the plan estimate annual sales revenues of $15,000,000 by March 2027 under a success scenario. The plan also anticipates that XL will be acquired by a strategic investor in March 2027, this being the exit strategy for its investors. Carls due diligence has determined that a typical price/revenue ratio for early growth biochip companies is about 3:1. Carl has introduced Susan to Leslie Neal, a partner in Technology Ventures Corp. (TVC). TVC is a regional venture capital firm. Like Carl, Leslie has significant experience with security technologies and feels that XL would be an ideal complement to TVCs portfolio of high-tech startups. TVC has expre.
