A. behavioral; cognitive
Explanation:
Kalanick is demonstrating the behavioral and cognitive component of his attitude.
Attitude refers to the positive or negative evaluation of an event or scenario.
There are three types of attitude which are:
- Cognitive attitude: it is the general perception or belief about a person or an object.
- Affective attitude refers to the way a person feels about a particular situation.
- Behavioral attitude refers to the way a person behaves in response to a situation.
From the given problem;
Kalanick created his own team within uber: this is a behavioral attitude in response to a situation at hand.
He believes he can achieve the "fastest, cheapest and the most efficient way to move from one place to another": this is a cognitive attitude.
His affective attitude would have been just to keep thinking about how to achieve his cognitive thoughts.

Answer: it’s better than doing nothing and at least it’s not the 1 mile run
Explanation:
a. A translation stop codon is added at the 3' end of the pre-mRNA.
c. A poly-A tail (50-250 adenine nucleotides) is added to the 3' end of the pre-mRNA.
d. Coding sequences called exons are spliced out by ribosomes.
Explanation:
In eukaryotes, during protein synthesis, the RNA must exit nucleus through the pores on the nuclear membrane and enter into the cytoplasm to undergo translation.
The exit processes of mRNA are: the 5’ capping, 3’ Poly-A tail, and pre-mRNA splicing.
The 5’capping is the initial step with addition of 7-methylguanosine cap to the 5’ end of the mRNA by phosphate linkage. This process protects the mRNA from degrading and helps to initiate translation processes.
The 3’ Poly-A tail step is the cleaving of pre-mRNA and addition of addition of around 200 A nucleotides or the 3’poly (A) tail to the mRNA by the poly (A) polymerase enzyme protein complex. This prevents pre-mRNA degradation, facilitates movement of mRNA to the cytoplasm, and initiates translation.
Pre-mRNA splicing is done to remove the introns from the mRNA because they are not part of function protein coding. The exons which take part in protein coding sequence are spliced once the introns are excised.
Finally, the resultant mRNA will exit the nucleus and enter the cytoplasm to undergo translation
