Answer: False
Explanation:
Hemoglobin can be defined as red protein that transports oxygen to various parts of the body according to its need.
It does not transports the same amount of oxygen to all the tissues. Some tissues of the body might require more more oxygen and some cells might require less amount of oxygen.
It depends on the state of activity. It transports more oxygen to the tissue that require it the most.
Example: The skeletal muscles of the body require more oxygen and it can be more than 80% .
Hence, the given statement is false and hemoglobin does not releases the same amount of oxygen to each and every tissue of the body.
The statement that is true of Oparin and Haldane's theory is : the primitive organic molecules were formed in an oxidizing atmosphere in the primordial soup
This is one of the theory that determined how life on earth developed. It was one of the most influental theory on the matter

A mutation is a change in DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, and its physiology.
1. The right answer is A nerve cell stimulates a muscle cell to contract (it is intercellular communication).
Cellular communication is the set of mechanisms that allow a cell, tissue, and organism to receive, interpret and respond to signals from other cells or its environment.
All cell types have these mechanisms but some have developed them more:
*the nervous system,
* organs of the senses,
* endocrine system,
*immune system.
This allows the body to maintain its homeostasis, its balance, allowing the interaction between these systems.
2. The right answer is the enzyme-linked receptor.
Receptor-enzymes associate on the same protein of the plasma membrane the functions receptor (mediator binding) and effector (enzymatic activity at the origin of intracellular message transduction): these are catalytic receptors. Thus, the receptor itself has enzymatic activity and the fixing of the messenger modulates this activity which may be of several types:
*tyrosine kinase
*tyrosine phosphatase
*receptors with guanylate cyclase activity
Answer:
it is uranium
Nuclear Fission Creates Heat
Reactors use uranium for nuclear fuel. The uranium is processed into small ceramic pellets and stacked together into sealed metal tubes called fuel rods.
