Answer:
This question is incomplete
Explanation:
This question is incomplete but generally it seem to test the knowledge of accuracy. Accuracy is the closeness of a measured value to the specific or actual value of the substance being measured. Hence, the smaller the entire scale that can contain all the substance being measured, the higher the possibility of accuracy to be achieved. For example, a pen of 10.4 cm in length can be better/accurately measured (length) with a 30 cm meter rule than a 1 m meter rule.
From the question, the 50 mL beaker will provide a "more accurate" measurement of the volume of the bromine than the 100 mL beaker if the 50 mL beaker can contain all the sample of bromine water provided.
They live in extreme environmental conditions.

Explanation:
Complete configuration
The process of sexual reproduction involves two parents, each contributing one gamete (and different types of genetic information, in shape of DNA). Gametes are produced by a process, called meiosis, which starts by the duplication of the chromosomes, followed by two rounds of cell divisions and halving of the chromosome number. Gametes have half the chromosome number of other adult cells of an organism. When two gametes merge, zygote is created.
A key feature of meiosis is the exchange of chromosome pieces which occurs in the first division of this process, called recombination or crossing over. Recombination is a very important source of genetic variation between individuals of sexually reproducing species, and the driving force for the process of natural selection.
