Answer:
Density, ![d=0.82\ g/cm^3](https://tex.z-dn.net/?f=d%3D0.82%5C%20g%2Fcm%5E3)
Explanation:
It is given that,
Mass of unknown liquid is 20.5 kg
Volume, V = 25 mL
We know that, 1 mL = 1 cm³
25 mL = 25 cm³
The density of the substance is equal to its mass per unit volume. So,
![d=\dfrac{m}{V}\\\\d=\dfrac{20.5\ g}{25\ cm^3}\\\\d=0.82\ g/cm^3](https://tex.z-dn.net/?f=d%3D%5Cdfrac%7Bm%7D%7BV%7D%5C%5C%5C%5Cd%3D%5Cdfrac%7B20.5%5C%20g%7D%7B25%5C%20cm%5E3%7D%5C%5C%5C%5Cd%3D0.82%5C%20g%2Fcm%5E3)
So, the density of this substance is
.
These organisms didn't fit into the classification system of the time. The system had to be changed to incorporate this new group or organisms. ... Changes to the classification system have meant that the classification of some species of organisms has changed too...
Answer:
Chloroplast
Explanation:
Endosymbiosis theory explains the origin of chloroplast and mitochondria in the eukaryotic organisms.
When the pro-eukaryotes engulfed the blue-green algae or photosynthetic bacteria, these bacteria formed the symbiotic relationship with the pro-eukaryotes. These photosynthetic bacteria transformed into the chloroplast organelles of the eukaryotes which can capture the sunlight and use it in the synthesis of glucose molecules. These eukaryotic cells later formed the plant kingdom.
Thus, the chloroplast is the correct answer.
The four benefits of rearing the farm animal mentioned area the Good pleasant and amount of milk that may be produced and it could upload to the earnings of the farmer.
<h3>What types of animal systems are there?</h3>
According to FAO, there are 3 predominant farm animal control systems: combined manufacturing. in-depth farming systems “landless” enormous manufacturing gadget.
- A farming gadget is described as a complicated interrelated matrix of soil, plants , animals, implements, power, labor, capital and different inputs managed in component through farming households and encouraged to various stages through political, economic, institutional and social forces that perform at many levels (Dixon et al., 2001).
- Benefits of farm animals farming: 1) Good pleasant and amount of milk may be produced and it could upload to the earnings of the farmer. 2) Draught labor animals may be produced and utilized in agricultural work. 3) New range which can be proof against illnesses may be produced through crossing types with the preferred traits.
