A- uracil, test prep question
Answer:
C)Both proteins bind ATP and F-actin
*C option is not mentioned* there is a flaw in the question
Explanation:
Two families of motor proteins, kinesin and dynein, transport membrane-bounded vesicles, proteins, and organelles along microtubules. Nearly all kinesins move cargo toward the (+) end of microtubules (anterograde transport), whereas dyneins transport cargo toward the (−) end (retrograde transport).While
both the protiens have globular ATP-binding heads that function as the motor domain and interact with the microtubules.
False, I'd say. Mammals usually adapt based on environment. Now, I know predators are "apart" of the environment, but I don't think that'd be it. I'd bet more money on saying mammals evolve based on environment adaptation. Sorry if I didn't answer your question or if I didn't get my point across well.
Answer:
The correct answer is - option B. They are small because they lack a nucleus.
Explanation:
Red blood cells or erythrocytes are specialized cell that produce in bone marrow and have specific role such as carrying oxygen from lungs to deliver it to the various organs and carry out carbon dioxide.
In mammals these cells lack cell organelles such as nucleus and mitochondria, a major factor that determined its smaller size. The size of RBC are move through narrow vessels throughout a organism because of its specific size and shape that provide it space for hemoglobin and allow to be flexible and bend to move through narrow vessels.
Thus, the correct answer is : option B. They are small because they lack a nucleus.

The exact cause of most types of the diabetes is unknown. In all the cases, the sugar builds up in the bloodstream. This is because of the pancreas that doesn't produce that enough insulin. Both type 1 and in type 2 diabetes that may be caused by the combination of the genetic or the environmental factor
