Generally speaking, scientists have developed four different methods of determining the age of the earth. By using these methods, or a combination of them, the age of geological formations created by past events and even the fossilized bones of prehistoric animals can be determined.

Answer:

New technologies allow scientists to perform calculations that are increasingly more accurate and correct in relation to the age of the earth.

Explanation:

According to most scientists who study the Earth's geological past, our planet is approximately 4.5 billion years old. However, this is not a totally accurate measurement, as the margin of error for this dating is estimated at 10%. Several times before, the age of the Earth was recalculated as new evidence was found and techniques improved. What was seen is that, with each measurement made, the Earth was older than imagined.

The advancement of technology, allows this margin of error to become smaller and smaller, because it allows scientists to calculate the age of the earth with precision more and more and closer to the correct one.

Fofino [41]

Answer:

The correct answer is - end of cytokinesis.

Explanation:

Cytokinesis :- a procedure that partitions the cytoplasm and plasma layer of a cell, bringing about two indistinguishable cells that contain their own DNA, nucleus, nuclear membrane, and plasma membrane.  

During the last phase of the cell cycle, cytokinesis permits the cell to complete the process of isolating, making two cells with indistinguishable duplicates of DNA  

The cell squeezes in the equator area with the assistance of a ring of contractile protein filaments. The formed cleavage furrow develops until the two cells squeeze off totally.

Thus, the correct answer is - end of cytokinesis.

Why do embryologist study embryos?
ch4aika [34]
Embryologist study embryos because Embryology is central to evolutionary developmental biology ("evo-devo"), which studies the genetic control of the development process (e.g. morphogens), its link to cell signalling, its roles in certain diseases and mutations, and its links to stem cell research.

Blood enters which of these vessels during ventricular systole?
Ganezh [65]
Ventricular systole is when the ventricles of the heart as the result of electrical activity which helps to pump blood. During ventricular systole oxygenated blood is pumped from the left ventricle through the aortic valve and aorta. Simultaneously deoxygenated blood is pumped from the right ventricle through the pulmonic valve and pulmonary artery to the lungs. Using this explanation blood enters  the aorta and pulmonary artery during ventricular systole. <span />
