Carbon can be obtained when using coal
Answer: C). Oxygen binding
Explanation: Hemoglobin is a protein present in the red blood cells that transports oxygen to the body cells and tissues. Hemoglobin has four subunits with four binding sites: one binding site on each protein subunit. Hemoglobin exists in two states: the tensed (T) state and the relaxed (R) state. The T state has low affinity for oxygen while the R state has high affinity for oxygen. The binding of oxygen to the T state triggers a conformational change in the protein and its transition to R state. The binding of oxygen to one binding site on hemoglobin increases the binding of oxygen to the remaining subunits, this phenomenon is known as cooperativity.
Answer:
<em>As scientists learned more about genetics and biochemistry , some organisms were moved out of existing kingdoms and into new ones.</em>
Explanation:
As the researches in the scientific world continued, scientists realized that there were, in fact, many genetic diversities present in organisms which were placed in the same groups. Hence, they realized that due to these differences these organisms should not be kept in the same group. As a result, the groups in the classification system increased.
Carolus Linnaeus just grouped organisms based on their features. But today, scientists classify organisms based on various perspectives such as the evolutionary history, genetic similarities etc.
Answer:
It is a polar molecule
Explanation:
There is no such thing as tri-polar. Water cannot be non-polar due to its partial charges. Water is not a chimeric molecule because it has a plane of symmetry.
Answer:
The correct answer is - 4 kingdoms.
Explanation:
According to the current classification or taxonomic system used by many taxonomists is the modern Linnean classification system and according to this, there are four kingdoms Protista, Fungi, Plantae, and Animalia in the domain eukarya. there are two more kingdoms in prokaryotes that are monera and archaebacteria
Thus, the correct answer is - 4 kingdoms.
