Plant cells have cell walls, while animal cells don't have cell walls.
Mature and established trees die for a combination of reasons but sudden browning of foliage is typically associated with a lack of water supply to the canopy. Water supply can be cut off to the canopy due to obvious issues including deficiency or root damage.
<h3>What is Carbon?</h3>
- Carbon is a chemical component with the symbol C and atomic number It is nonmetallic and tetravalent—its atom makes four electrons unrestricted to form covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon produces up only about 0.025 percent of Earth's crust.
- Carbon is employed in some way in almost every industry around the globe. It is used for fuel in the form of coal, methane gas, and crude oil (which is used to produce gasoline). It is used to make all sorts of fabrics including plastics and alloys such as steel (a mixture of carbon and iron).
- Carbon is a chemical element with the symbol C and atomic number 6. Categorized as a nonmetal, Carbon is a solid at room temperature.

Saturated fatty acids are different to unsaturated fatty acids because they have no C=C double bonds.
<h3>What are the differences between saturated and unsaturated fatty acids?</h3>
- Saturated fatty acids do not have C=C double bonds, while in unsaturated fatty acids there is at least one C=C double bond in the fatty acid chain.
- Saturated fats are usually solid at room temperature and are derived from animal sources, whereas unsaturated fats are usually liquid at room temperature and are from plant sources.
- One must reduce the amount of saturated fat in their diet and consume more unsaturated fats like olives, seeds and nuts.
- Unsaturated fats can be monounsaturated (contains only C=C double bond) or polyunsaturated (contains two or more C=C double bonds).

False, pernicious anemia may take up to 5 years to show symptoms. However, the oxygen starts to get depleted within the first 6 months in thalassemia major.
Pernicious anemia:
In this condition, the body is unable to absorb vitamin B12 which leads to lowered amount of red blood cells which are responsible for carrying oxygen throughout the body. It is an autoimmune disease in which antibodies attack their own cells in the lining of the stomach which affects the absorption of vitamin B12. The symptoms of pernicious anemia are dizziness, fatigue, diarrhea, constipation, breathlessness, and loss of appetite. The depletion of oxygen is seen in thalassemia major within 6 months.
