<h3><u>Answer;</u></h3>
<em>16 half-cup servings of beans and 4 three oz. servings of shrimp</em>
<h3><u>Explanation and solution;</u></h3>
Let x = number of half-cup servings of beans
Let y = number of 3 oz. servings of shrimp
We will have 2 equations, one for carbs and one for calories
7x + 9y = 148
30x + 190y = 1240
30(7x + 9y) = 30(148)
-7(30x + 190y) = -7(1240)
210x + 270y = 4440
-210x - 1330y = -8680
-1060y = -4240
y = 4
7x + 9y = 148
7x + 9(4) = 148
7x + 36 = 148
7x = 112
x = 16
Hence; X = 16 and Y= 4
16 half-cup servings of beans and 4, 3 oz. servings of shrimp
Answer:
Because each subject in an experiment has to have equal conditions to ensure the most accurate results. And water temperature is known to impact plant growth. An experiment using different water temperatures is a terribly inaccurate experiment.
Circulatory system, respiratory system, and the digestive system.
<span>There are three types of hybrid reproductive barriers. The one described is called hybrid breakdown. In hybrid breakdown as the hybrid organisms continue to reproduce each sequential generation becomes less viable, healthy and loses it's ability to reproduce. The other two hybrid reproductive barriers are hybrid sterility and hybrid inviability. Hybrid sterility results in healthy organisms that can not reproduce at all since thy are sterile. Hybrid inviability results in organisms that are not strong enough to survive and often die while juveniles.</span>
