Answer:
8%
Explanation:
Given that,
Mass of solute = 8 g
Mass of soultion, (mass of alloy) = 100 g
We need to find the percent by mass of 8.0g copper is added to enough zinc to produce 100g an alloy. It can be calculated by the formula as follows :

So, the percent by mass is 8%.
The best suited group for the mentioned plant is Angiosperms and monocot.
Answer: Option C
<u>Explanation:</u>
As mentioned the seed of the plant has one cotyledon and the specific name for these type of plants whose seeds has one cotyledon is called Monocot, Suppose if the seed of the plant has two seeds, It is called dicot.
Hence we can conclude that the mentioned plant comes under monocot and not dicot. On the other hand, Angiosperms refers to the plants that has flowers with it and gymnosperms usually includes plants without flowers and hence we can classify the plant as Angiosperm and monocot.
Answer:Thirty years ago, 45 out of 200 individuals, or 22.5% of individuals, were at least 1.2 meters tall. Presently, 50.5% of individuals are at least 1.2 meters tall. Meanwhile, individuals below 1.2 meters in height have decreased significantly between the two years of data. This data supports the argument that directional selection is occurring.
Explanation:
Answer:
Cell–cell interaction
Explanation:
Based on the scenario being described it can be said that the developmental process that has most likely been affected are known as Cell–cell interaction. These are the direct interactions that exist between cell surfaces that allow them to communicate with one another. Doing so by receiving signals and initiating transduction pathways. Therefore since these are functions that have been disrupted it's safe to say that the Cell-cell interaction has been affected.
