The transmembrane protein Tango1 is a packaging protein that helps some secretory proteins leave the endoplasmic reticulum (ER)

after synthesis. Knocking down Tango1 by RNA interference impairs the incorporation of collagen VII, but not collagen I, into transport vesicles destined for the Golgi apparatus. The protein contains a lumenal N-terminal SH3 domain and a cytosolic C-terminal proline-rich domain. Which of the following proteins would you expect to interact with the N-terminal and C-terminal domains of Tango1, respectively?
A. Procollagen VII; COPI components
B. Procollagen VII; COPII components
C. Procollagen I; COPI components
D. Procollagen I; COPII components
E. COPI components; procollagen I

Answer:

Procollagen VII; COPII components.

Explanation:

The endomembrane system present in eukaryotes divides the  cell organelle into the structural and functional compartment. This helps in the transport of protein, its signalling and processing of protein.

Tango1 is the packaging protein that are destined to the golgi. The interaction of procollagen VII and CopII vesicle with tango is important as these helps in the transport of tango protein to the golgi. The cop II coated vesicle is important for the transport of the protein that are destined to golgi.

Thus, the correct answer is option (B).

Two species of sea urchins live practically side-by-side in sandy bottoms. The two species appear to have the same diet: drift seaweeds and other bits of organic matter. They can live in the same environment without competing.

As it compels them to live in the same environmental surroundings so the characteristics of living nature also get developed as their current following situation that's helping them to get the same food & habitat.

Mrrafil [7]
<h2>Answer is option "C"</h2>

Explanation:

  • To clone a plant means to create an identical copy of an adult plant. These identical copies become young plants that in turn become adult plants that can be cloned again. This process can go on indefinitely
  • The most common method of cloning plants and the one that has been used for a very long time is that of taking cuttings from an adult plant. A cutting is a stem or leaf that is cut from an adult plant. The cutting is then planted into moist soil or other moist growing media. The cutting will produce roots of its own and then become a whole new plant identical to the original adult plant. Not all plants can be cloned via cuttings, though
  • Vegetative proliferation works in light of the fact that the finish of the cutting structures a mass of non-particular cells called a callus. With karma, the callus will develop, gap and structure different specific cells (roots, and so on.), in the end framing another plant
  • Hence, the right answer is option C "Clone the plant"

What is the net volume of fresh air that enters the alveoli each minute, assuming that the breathing rate is 10 breaths/min, the
kondaur [170]

Answer:

6,500 mL

Explanation:

We are asked to find the total volume of air that effectively entered to the alveoli in one minute so that oxygen could be exchanged for carbon dioxide and leave the body through exhalation.

The problem says that the normal breathing rate is 10 breaths per minute, and for each breathe it takes 800 mL of air. But not all air enters the alveoli because it says there are 150 mL that are not effectively used by the alveoli. Therefore, the net amount of air used in each breathe is 800 ml - 150mL, giving us a total amount of 650 mL of air.

Now that we have the net amount of air for each breathe, we have to multiply it by the total breaths a body makes in one minute. In this case, the breathing rate is 10 breaths/min.

So, to obtain the final answer we just need to multiply the amount of net air per breathe (650 mL) times the number of breathes in one minute (10 breathes); that is 650 mL/breath x 10 breaths and gives us 6,500 mL.
