Group A
Explanation:
Answer:
C. Group A
Explanation:
First, let's define accuracy and precision.
Precision: the measurements are all close to each other
Accuracy: the measurements are close to the true value.
Let's examine the answer choices.
A. Group C: 32.1 g, 35.0 g, 25.0 g
This is not accurate or precise. The measurements are far from each other and only one is close to 25 g.
B. Group D: 20.0 g, 25.0 g, 30.0 g,
The measurements are relatively accurate and precise. They are within 5.0 grams of each other and the true value.
C. Group A: 28.5 g, 28.4 g, 28.5
The measurements are the most precise. They are all within 0.1 gram of each other. They are also somewhat accurate.
D. Group B: 25.5 g, 25.0 g, 24.8 g
The measurements are not precise or accurate. There is one measurement that is far from the true value and the other measurements.
Therefore, the most precise measurements are from Group A.

Dog breeders maintain the purity of breeds by keeping dogs of different breeds apart when they are fertile. This kind of isolation is most similar to which of the following reproductive isolating mechanisms? a. temporal isolation b. behavioral isolation c. habitat isolation d. gamete isolation
Answers
The isolation practiced by dog breeders to maintain the purity of breeds is most similar to behavioral isolation
(option b). is correct.
How do we explain?Behavioral isolation is a reproductive isolating mechanism in which individuals of different species or populations have different behaviors or mating rituals that prevent them from successfully mating with each other. In the case of dog breeders, they keep dogs of different breeds apart during their fertile periods to prevent them from mating and producing mixed-breed offspring.
This behavioral isolation helps to maintain the purity of the specific breeds.
Therefore, (option b). is correct.

Answers
Answer:
Carbon is released into the atmosphere.
Explanation:
Carbon is released into the atmosphere. So, the correct option is (A).
What is Carbon?Carbon is defined as a chemical element, like hydrogen, oxygen, lead or any other element that is very abundant in the periodic table. It exists in pure or nearly pure forms such as diamond and graphite, but can also combine with other elements to form molecules.
Carbon is used in metal smelting in the form of charcoal (from wood) and coke (from coal) as impure carbon, which is particularly important in the iron and steel industries. Graphite is used in pencils, to make brushes in electric motors, and in furnace linings, while activated charcoal is used for purification and filtration.
When we burn we the human fossils, some gases like Carbon is released into the atmosphere.
Thus, Carbon is released into the atmosphere. So, the correct option is (A).

Ya que normalmente se expresará el alelo dominante, mientras que el efecto del otro alelo, llamado recesivo, queda enmascarado. Pero cuando hay codominancia, entonces ningún alelo es recesivo y el fenotipo de ambos alelos es expresado.

What is the outcome of all chemical changes when two substances are combined?
A- A new substance forms with identical properties
B- The two substances release an odor
C- The two substances change color
D- A new substance forms with different properties
Answers
Chemical changes:-
occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
Hope this can help.
Answer:
D- A new substance forms with different properties
Explanation:
When a chemical change occurs, it causes the matter to form into a completely new substance. Because of this, the new substance will have different properties than the original substance. Options B and C are true for some chemical changes, but not all changes. Option A is incorrect because the substance has different properties than the original substance. Thus, Option D is correct.

What was the problem with this genetic engineering solution?
Answers
Answer:
The genetic engineering produced on these tomatoes was the solution to reduce the amount of chemical usage to crops as well as introducing a greater disease resistance, insect resistance, and increase shelf life. Conclusively, scientists and farmers still wanted to keep their natural color and flavor, yet change it into a more positive way. 70 years ago, spoke of the dangers of nightshade foods, covering all this ground, and stating that traditionally in South America, where potatoes and tomatoes come from they were eaten as medicine – that is given specifically for a short period time for a specific condition.
