Explanation:
Hello!
We can observe that:
R red eyes
r white eyes
The possible gametes for the female are XR and Xr.
The possible gametes for the male are Xr and Y
Xr Y
XR XRXr XRY
Xr XrXr XrY
The expected offspring is:
a red-eyed female (XRXr)
a red-eyed male (XRY)
A female with white eyes (XrXr)
A white-eyed male (XrY)

It allows us to determine not only how and why organisms have become the way they are, but also what processes are currently acting to modify or change them !
Explanation:
Aristotle's model shows the planets in the celestial realm moving around the Earth in an orderly manner, in perfect circles and with uniform motion-neither speeding up nor slowing down.
Answer:
the magnetic direction of rocks along the surface of Earth and the age of rocks along the surface of Earth
Explanation:
The earth's magnetic field or geomagnetic field is believed to originate from the movement of molten iron and nickel in the outer core.
During a period in which the earth magnetic field is normal, crystallising magnetic minerals in magma records the orientation of the prevailing geomagnetic field. At other times when the field reverses and the magnetic field orientation changes, magnetic minerals in cooling magma stores this record.
To create a geomagnetic time scale, geologists can assign absolute ages to the records of these paleomagnetic anomalies which are the reversals. The rock is dated using radiometric techniques and each period of reversal is ascribed an absolute geologic age. Therefore, the magnetic direction of rocks along the surface of Earth and the age of rocks along the surface of Earth helps to build the geomagnetic time scale of the earth.
Lactic acid produced by fermentation causes the sour taste.
