Answer:
The correct answer will be options A, B and E.
Explanation:
Red blood cells or RBC or erythrocytes are the cells present in the connective tissue which forms the blood. RBC perform various functions in the body but the primary function is the transport of the gases in the body.
The RBC are continuously formed in the bone marrow region of the bone form the hemopoietic stem cell found in the bone marrow. These cells produce a large amount of RBC that is about 2 million cells per second in a healthy adult.
When RBC are formed posses nucleus but when mature, they lack nucleus that is genetic material and organelles like mitochondria so, they are not able to divide.
These RBC contain haemoglobin in their cytoplasm which shows high affinity to bind oxygen and low affinity to bind carbon dioxide to the iron group of haemoglobin.
Thus, options A, B and E are the correct answer.
Answer:Texas cichlid (Herichthys cyanoguttatus)
Explanation:
Texas cichlid (Herichthys cyanoguttatus, ex. Cichlasoma cyanoguttatum) is a large, good looking and at that rather aggressive cichlid fish. In the wild it inhabits in rivers of Texas (for example, Rio Grande, due to which the fish got its name Rio Grande cichlid) and in North Mexico.
D) gut with four stomach chambers. If you have anymore questions feel free to ask me.
Two stages that occur in the carbon cycle are: Animal respiration and emissions from factories
Animal respiration is carbon dioxide and water that is released into the atmosphere .
carbon emissions can be absorbed by plants and trees during photosynthesis to produce food.
2. Solar power is a sustainable way to gather energy as it does not harm the atmosphere and carbon emissions. However,sunlight may not always be available in winter months due to shorter days and longer nights. solar panels can also be very expensive to set up, but costs can be broken even over a period of years.
Nuclear power can be a cheap way to produce electricity as deposits of uranium and plutonium will last for the next couple of thousands of years (3000-4000 years). power plants can cost colossal amounts to set up but have relatively low running costs. please like and thank me that was a lot to write
