cell
Explanation:
That is the smallest unit of life, and every living thing has at least one cell, such as unicellular living things.
Answer: Diffusion
Explanation:
The osmosis is explained as the selective permeability of the membranes which allows the movement of the solute from higher concentration to lower concentration.
This is associated with diffusion which can be defined as the random movement of the particles in order to attain equilibrium.
The diffusion allows the movement of the particles and osmosis allows the movement of only selective materials.
b. Y is positively charged, has a mass of 200 kDa, it does not bind sugars.
c. Z is negatively charged, has a mass of 100 kDa, it does not bind sugars.
What will be the most efficient method to purify protein X from the mixture of X, Y, and Z?
i. washing
ii. drying
iii. ion-exchange chromatography
iv. gel filtration chromatography
v. affinity chromatography
Answer:
iii. ion-exchange chromatography
Explanation:
We have to purify the proteins and column chromatography is used widely for the purification of proteins. Ion-Exchange chromatography is also a type of column chromatography.
When the sugar binding protein X passes through the column, the sugar and proteins binds together by exchanging ions and coagulated out no matter what the nature of charge on proteins...
Answer:
B
Explanation:
Answer: I do think its a good idea cause it lessens pollution in the air we breathe in and stops us from burning fossil fuels
Explanation:
Banning passenger cars and promoting public transportation in cities is a good idea for reducing pollution and traffic congestion.
I believe that banning passenger cars and promoting the use of public transportation in cities is a good idea. This approach can help reduce air and noise pollution, alleviate traffic congestion, and improve overall quality of life. By encouraging people to walk, bike, or use public transportation, cities can create a more sustainable and livable environment for their residents.
One example of a city that has successfully implemented this approach is Copenhagen, Denmark. The city has an extensive public transportation system, including a well-connected network of bike lanes. As a result, more than 60% of residents commute by bike or public transportation. This has significantly reduced air pollution and traffic congestion in the city.
Additionally, adopting this approach can have numerous benefits, such as promoting physical activity, reducing carbon emissions, and improving public health. Overall, I believe that cities with comprehensive public transportation systems should consider implementing policies that restrict the use of passenger cars in order to create a cleaner, more sustainable urban environment.
