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.
A trade of chromosome segments among non-sister homologous chromatids happens and is referred to as crossing over.
Crossover happens while chromosomes, usually homologous times of the equal chromosome, spoil after which reconnect however to the specific quit piece. If they spoil on the equal location or locus withinside the collection of base pairs, the end result is an trade of genes, referred to as genetic recombination.
<h3>What are homologous chromosome?</h3>
Homologous chromosomes are made from chromosome pairs of about the equal length, centromere position, and marking pattern, for genes with the equal corresponding loci.
Thus it s well expalined.

Pathogens are microorganisms - such as bacteria and viruses - that cause disease. Bacteria release toxins and viruses damage our cells. White blood cells can ingest and destroy pathogens. They can produce antibodies to destroy pathogens, and antitoxins to neutralize toxins

Location of land, resources available around and for the land, environment around the soil, texture of soil and water availability.
<h2>Criteria needed for land use</h2>
Resources available around and for the land, environment around the soil, texture of soil and water availability are the criteria which can be used to determine the kinds of evidence that should be required in making decisions about land use.
If the land has all resources needed for agriculture then the land must be use for agriculture purpose while on the other hand, if the land has limited resources such as water and poor soil texture then the land will be used for infrastructure so we can conclude that available resources to the land decides the usage of land.
