Answer:
Grass-fed beef is the most sustainable choice. Grass-fed beef represents a net gain for the human food supply because cows eat grasses that we can’t eat (from land that is typically unsuitable for human crops) and turn it into beef that we can eat.
Explanation:
Cattle raised on a primarily foraged diet are termed grass-fed or pasture-raised; for example meat or milk may be called grass-fed beef or pasture-raised dairy. The term "pasture-raised" can lead to confusion with the term "free range", which does not describe exactly what the animals eat.
That said, grass-fed cows eat (mostly) grass, while grain-fed cows eat (mostly) an unnatural diet based on corn and soy during the latter part of their lives. To maximize growth, the cows are often given drugs, such as antibiotics and growth hormones.
Hi
I think a very important thing while working in a scientific laboratory is to have cooperation along with a sense of individual responsibility. There are many times when you are not expert in one scientific technique but your senior or fellow worker is because of his/her prior experience. At that point, the people of laboratory should cooperate with each other in giving some tips regarding performing a specific technique and getting the results with minimum time wastage. This does not mean that you take help from some one without giving them credit.
There should be a lab attendant in every lab who should be consulted for every problem so that he can assign some relevant worker to help you in the work. After you get the help, the attendant should confirm from both persons and keep a log about it which they should appreciate and give a fair credit about inquiries of higher authorities like supervisors.
Another important factor that is important for people is to have a sense of respect for each other. This is important to listen to others without just thinking about our own perspective and our own understanding. This also enables to understand a point from larger view and can help to bring a point in mind which we otherwise might skip.
The addition of dynactin caused dynein to travel farther along the micro tubule.
<u>Explanation:</u>
Dynein is a family of cytoskeletal motor proteins that move along micro tubules in cells. They convert the chemical energy stored in ATP to mechanical work. Dynein transports various cellular cargo, provides forces and displacements important in mitosis, and drives the beat of eukaryotic cilia and flagella.
Dynactin is a 23 sub unit protein complex that acts as a co-factor for the micro tubule motor cytoplasmic dynein-1. It is built around a short filament of actin related protein-1.
