Why are indices better than simple measurements for comparing fossil specimens?

Biology

Answer:

Indices are used to study fossil specimens and compare them against each other. They are based on concept of ratio hence better than simple measurements when it comes to comparative analysis. They compensate for the problems caused by other variable factors like size or specimen.

For example, to estimate if an organism is long or round headed simple measurement of cranial length or breadth can be done and the result can be given according to the selected parameter. However some specimens will have longer breadth than length and some will have longer length than breadth. So, it is better to measure both the parameters and find out their ratio. Hence, cranial index is used which is given by: (Cranial breadth/Cranial length)*100.

Why is understanding the structure of DNA and how it is replicated important? List some technologies and practical applications
UNO [17]

The discovery of DNA, as well as understanding of its functioning and structure, may well be the most essential findings of the last century.  

The impact of the discovery of DNA on medical and scientific advancement has been huge, whether it involves the manufacturing and creation of drugs to cure the deadly diseases or to identify the genes, which stimulate several of the diseases.  

The understanding of DNA and its structural composition has led to the discovery of various technologies that helps in the fields like genetic testing, identifying viruses, crime investigation, production of genetically modified organisms, and various others.

Answer:

Alzheimer's disease

Explanation:

Alzheimer's disease occurs when there is a presence of abnormally structured  neurons and a reduced amount of acetylcholine in the regions of the brain involved in reason and memory. These neurons have fibrous proteins present in the form of bundles around the nucleus and amyloid plaques. Malfunctioning of these regions of the brain results in a gradual loss of reason with memory lapses. It makes the person unable to perform any type of daily activity. The given symptoms represent the fact that she is suffering from Alzheimer's disease

How are mitosis and meiosis similar apex?
xeze [42]
1. Similarities:they are both processes of cell division by which cells reproduce.
They share several steps of the process(prophase, metaphase, anaphase e telophase, cytokinesis) but meiosis has another division also with those same steps.
In both cases the cell duplicates its DNA by pulling it apart into two sets, place the sets on each end of the cell, and then divide down the middle.
Both produce new cells based on their parent cells' genes.
