Answer:
Different types of rocks have different chemical composition.
Explanation:
Rock can be distinguished from each other by their chemical composition which is a product of the minerals they contain.
- A rock is an aggregate of minerals.
- Different suites of rocks have their inherent mineralogical composition and facie.
- This is because, these rocks form under different types of conditions from time to time.
- Igneous rocks form from molten rocks, sedimentary rocks form from pre-existing rocks and metamorphic rocks for under elevated temperature and pressure conditions.
- All these conditions plays important roles in the differentiation of minerals in the rock.
The key to solving this problem is density. Density determines the mass of a molecule for a certain volume. Kia is given a beaker containing 100 g which volume is at <span>100 mL mark. Then the density of the liquid would be:
</span>density=mass/volume
density= 100g/ 100ml= 1g/ml
If t<span>he water now comes up to the 50 mL mark, then the weight would be:
</span>density = mass/volume
mass = volume * density
<span>mass = 50ml * (1g/ml)= 50g</span>
Answer:
Explanation:
A. White blood cells have many lysosomes because they need to produce a lot of glucose and oxygen.
Lysosomes are found in all animal cells, but are most numerous in disease-fighting cells, such as white blood cells. This is because white blood cells must digest more material than most other types of cells in their quest to battle bacteria, viruses, and other foreign intruders.
Answer:
Vascular plants are plants found on land that have lignified tissues for conducting water and minerals throughout the body of the plant. Non-vascular plants are plants mostly found in damp and moist areas and lack specialized vascular tissues. Vascular plants are also known as tracheophytes.
