In sexual reproduction, offspring are similar to their parents, but unique as well.
a. true
b. false

The given statement is true.

Explanation:

Different strategies are used by living species for generating offspring, however, the majority of them come into the categories of either asexual or sexual reproduction. The offspring in asexual reproduction are genetically similar to a single parent. On the other hand, in sexual reproduction, two parents take part in providing genetic information to generate a unique offspring. Thus, the given statement is correct.  

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

they absorb it i think

not sure
