Answer:
Golgi apparatus
Explanation:
The Golgi apparatus is an organelle found in most eukaryotic cells, i.e. cells with a clearly defined nucleus. The purpose of the Golgi apparatus is to transport, modify, and package proteins and lipids. If a cell affected by an environmental toxin ended up with misplaced proteins, we could conclude that the organelle that is no longer functioning properly is the Golgi apparatus.

Answer:
But if scientists want to know what Earth's climate was like hundreds of thousands to millions of years ago, they study sediment cores and ice cores. Sediment cores come from the bottoms of lakes or the ocean floor. Ice cores are drilled from deep — sometimes miles — below the surface of the ice in places like Antarctica.
Answer:
The proportion 'p-hat' that were cyanobacteria is 0.76
Explanation:
The proportion of cyanobacteria is the relationship between the whole sample and the actual quantity of cyanobacteria found in the sample, that were not other algae. In general, proportions are written as fractions. The<em> numerator is the number of cyanobacteria in the sample, while the denominator is the total number of organisms in the sample</em>.
So, in the exposed example we know that
- The sample was composed of 50 algae
- There were two categories for the sample: algae that were cyanobacteria, and algae that were not cyanobacteria
- Algae that were cyanobacteria = 38
- Algae that were not cyanobacteria = 12
If we want to study the relationship between the sample and cyanobacteria and express it as a proportion, then we need to divide the number of cyanobacteria by the number of algae in the sample. This is
38/50 ----> Fraction expression of the relationship between cyanobacteria
and the sample
0.76 ----> Proportion of cyanobacteria in the whole sample.
Answer:
Un elemento químico es un tipo de materia constituida por átomos de la misma clase. En su forma más simple, posee un número determinado de protones en su núcleo haciéndolo pertenecer a una categoría única clasificada por su número atómico, aun cuando este pueda desplegar distintas masas atómicas.
