Answer: The probability of having an offspring with type A blood is 1/4.
Explanation: Since each of the parents have a recessive allele for blood type O, their genotypes are IAi and IBi for the father and mother respectively. A cross between them will produce four offsprings: one with type AB blood, one with type A blood, one with type B blood and one with type O blood.

Answer:
A number of reactions may occur simultaneously in groundwater and cement-based materials, including the dissolution of portlandite that is generated from the intrusion of hydrogen ion, the increase of the concentration of calcium in the pore solution, formation of ettringite by sulfate attacking the cement, and the dissolution of Calcium–Silicate–Hydrate (CSH) gel by chloride entering the cement, and the formation of Friedel’s salt
Explanation:
Answer:3,4,5.
Explanation:
These supplements are just for complementing the naturaly available food subtances.And in some cases in adults to boost reduced quantities in old people.
However overconsumption of these materials have adverse effects Besides these products(minerals and vitamins can not replace the naturaly available components of fruits and vegetables, because they are synthetic, and the chemical components can affect the body physiological mechanisms especialy of the kidney and liver.Unlike natural components that are easily metabolise by the's ogans.
Answer:
B
Explanation:
If the traits are favorable this means nature would select it.
Answer choice: [C]:
_________________________________________
V = d / t = 1800 mi / 40 min = 180 mi / 40 min = 45 mi / min .
Which very well could be "Answer choice: [C]: 45 m/min" ; except, this answer choice may have been written incorrectly—and should read:
"45 m/min."
________________________________________________________
Now, notice that all the answer choices given are in "meters" per (unit time—seconds or mins.
So, we need to convert:
45 mi. to "meters", or "m".
______________________________________
Note the following conversions:
_______________________________________
1 mi. = 1750 yd
______________________________________
3 ft. = 1 yd.
____________________________________
1 m = 3.2 ft.
_____________________
So, 1 mi. = ? m ;
_____________________
1 mi * ( 1760 yd/ mi) * (3 ft / 1 yd) * ( 1m / 3.2 ft) = _?_ m ?
_____________________________________________________
On the "left hand side" , the units of "mi", "yd", and "ft" ; cancel to "1" ;
____________________________________________________
and we are left with:
______________________________________
[(1760 * 3)] / [(3)*(3.2)] m = (5280 / 9.6) m = 550 m .
______________________________________________
So, we have: 550 m / min ; which match NONE of the answer choices.
However, it is possible that choices A or B, which are given in "m/sec" (meters per second); are among the correct choices.
____________________________________________
So, we convert: 550 m / min to: "m / sec " ;
______________________________________
( 550 m/ min)*(1 min/ 60 sec) = (550/60) m/sec = (55/6) m/ sec
= 9 1/6 m / sec .
_____________________________________________________
which is: None of the above.
______________________________________________________
Unless the answer choices were written incorrectly.
