Answer:
The two main forms of eye makeup were grepond eye paint and black kohl. The green eye paint was made of malachite, a copper carbonate pigment, and the black kohl was made from galena, a dark grey ore.

I took the test.
Answer:
a space between the bones of the skull in an infant or fetus, where ossification is not complete and the sutures not fully formed. The main one is between the frontal and parietal bones.
Answer:
The correct answer is C
Explanation:
In asexual reproduction method, the offspring generated is identical genetically to the parents. But this is not the case in sexual reproduction. The reason being that the gametes or sex cells produced has only one set of chromosomes and are therefore haploid after the process of meiosis. Meiosis is the process when the offspring formed has chromosomes from two parents and is not identical to the parent. Only certain characteristics are inherited by the offspring from both the parents and offspring has different set of characteristics.
There is a process of assortment taking place inside the cell when the double set of chromosomes becomes one set in a gamete. Out of the pair of chromosomes, there is a random selection. Due to this random assortment, there is a genetic variation between the gametes as the gene alleles on the chromosome are not the same. This principle is said to be the Mendel’s first law of segregation.
Another process of combining chromosomes is the crossing over during the meiosis stage which results in variety of chromosomes. We can say that recombination is possible.
Hence, we can note that during assortment and crossing over, there is no chance for two offspring to be identical to the same mother or father with the exception of identical twins. In the case of identical twins, the genetically identical characteristics develops from same fertilized egg.
From the above process, the structure of gene gets changed creating a variant that can get transmitted to next generation. The change is caused by altering the single base units of DNA or rearranging larger section of genes.
Answer:
The correct answer is 3. Endosymbiotes
Explanation:
According to the endosymbiotic theory, mitochondria was a prokaryotic organelle which was engulfed by ancestral cell. Then this bacteria remain in a symbiotic relationship with ancestral cell and evolved in mitochondria which can synthesize ATP and replicated its own genome, able to duplicate and divide.
So mitochondria are considered as endosymbiotes which means they are organism which lives inside others body and cannot live or function on their own. This theory is supported by genetic evidence that shows similarities between mitochondria and bacteria. So the correct answer is 3.
