Answer and Explantion
Collect data-This should be the first step in coming up with a design of an instrument to measure a certain property. The data should comprise of the air temperatures, the wind speed values and recorded peak times for the ocean currents.
Build a prototype-This is sample equipment built from the data obtained to be used as a test instrument in predicting the catastrophic weather .The prototype is a mini design of the actual design.
Evaluate the result of their system-The results obtained from the prototype can be used for evaluation to determine the working of the designed devise. The results produced should show a connection that can be used to predict the weather according the values of temperature, wind speed and ocean current values.
Modify their design-After analyzing the results according to the parameters set for the design, the prototype can be improved to obtain a final design which will indeed produce the required results.
Answer:
Parents: Yellow (Aarr) and Grey (AaRr)
Explanation:
Given:
allele A = yellow
allele R = black,
Heteroozygous = gray
Genotypes of the parents:
yellow (Aarr) - female
gray (AaRr) - gray
cross between these
Parents: Yellow (Aarr) and Grey (AaRr)
Gametes: (Ar, ar) and (AR, Ar, aR, ar)
F1 (Punnet square)
----|----- AR ------|------- Ar ------|------ aR -----|----- ar
Ar | AARr (gray) | AArr (yellow) | AaRr (gray) | Aarr (yellow)
ar | AaRr (gray) | Aarr (yellow) | aaRr (black) | aarr (cream)
Ratio: 3/8 yellow : 3/8 gray : 1/8 cream : 1/8 black
Answer:
They haven't yet, that is a myth. Rattlesnakes still have a rattle and probably always will.
Explanation:
Yes they contain a permanent vacuole
