Answer:
The analysis of protein structure by frozen electron microscopy can be divided into three processes：
1. Sample preparation: the biomacromolecule sample is frozen rapidly in liquid nitrogen, and the water in the macromolecule exists in the form of glass.
2. Data collection: irradiate the sample and the ice near the sample with low energy electron beam, and record the scattered signal with detector.
3. Three dimensional reconstruction to build protein model: three-dimensional structure of protein is built by two-dimensional projection from different angles.

Answer: Homo habilis
Explanation: about 2.31 million years ago to 1.65 million years ago they existed and if An anthropologist finds a fossil that is 2 million years old it's most likely to be a Homo Habilis
Chromosomes are parts of a cell that carries genetic information inform of genes, they contain DNA molecules packaged around histone proteins. Diploid number of chromosomes means that a cell has both sets of homologous chromosomes while haploid is used to refer to a cell that has one set of chromosomes and therefore a single set of genes.Mitosis is a type of cell division that takes place in the somatic cells (body cells) resulting to two daughter cells with the same number of chromosomes as the parent cell (diploid). Therefore, in this case a somatic cell will have 48 chromosomes (diploid number 2n).
the answer is frameshift because deleted one out would shild the whole sequence
