I would say that the answer is A. Answers B and C are definitely wrong because DNA in eukaryotic cells are in the nucleus while two identical daughter cells are created from asexual reproduction. Answer D is wrong because you can compare two different organisms like a human and a dog. Since both are eukaryotic they will have eukaryotic cell structures with their organelles. I believe that A would be correct, if you remember the the level of organizations, then you know that cells are simple, as cells become tissues, they become a little complex, as tissues become organs, they get a little complex, finally when organ systems are formed, they are highly complex from the organs, tissues and cells. Hope that answered your question.
Answer: A. Nervous tissue
Explanation:
The spinal cord, together with the brain, forms the central nervous system and the most important part of the body for the transmission of nerve impulses, that is, information for the functioning of the body. The spinal cord as well as the entire nervous system is made up of nerve cells, whose receptors, neurons, transmit vital information to the brain where they are processed, after which feedback is sent in the form of some kind of command from the brain what certain parts of the body should do, i.e. how to function. In this way, the complete functioning of the organism is regulated. How much to increase the work of a particular organ, glands, how much the heart needs to pump blood, how to move hands, legs, all this is regulated by information from the brain through nerve cells, neurons.
If nerve cell damage occurs, which can be a result of physical injury, or a disease that causes nerve cell disruption, then there is no way to send information to the brain and feedback from the brain, which causes paralysis of certain parts of the body, sometimes the whole body, dependent on the injury and the degree of damage to nerve cells, neurons.
Low levels of hormones can result in various conditions, like type I diabetes, hypothyroidism. However, issues can also take place when the levels of hormones are too high. In the most usual terms, too much hormone is considered as a hyper state.
One of the most usual conditions of hormonal extremes is too much amount of thyroid hormone, also called hyperthyroidism. Another illustration of an upsurged level of hormone is a condition called Cushing's syndrome.
A reason the level of the hormone can be high in the body is that the hormones by themselves cannot function adequately. Thus, the body tries to compensate by producing extra hormones. This is typically considered as hormone resistance.
The signs and symptoms of hormone resistance are generally identical to exhibiting low hormones. However, the treatments for hormone resistance and hormone deficiencies can change, that is, sometimes different and sometimes the same.
