Answer;
Seedless plant.
The fossil of a plant reveals that it produced spores that were used for reproduction. It was a seedless plant.
Explanation;
-Seedless vascular plants are plants such as fern and horsetails, liverworts, mosses; which contain vascular tissues, but do not produce flowers or seed.
-These plants reproduce using haploid , unicellular spores instead of seeds.
-These plants have life cycles with two distinct stages; one in which spores are produced and one in which sex cells are produced.

In the situation where Jeremy is digging in the garden and feels the spade hit a rock, the functioning of sensory, relay, and motor neurons is crucial in his body's response to this stimulus.
When Jeremy was digging in the garden, he felt the spade hit a rock. This is sensation was facilitated by sensory neurons which picked up the external stimulation and sent the information in the form of electrical impulses from the nerves in his hands towards his spinal cord and brain. This sensory information travels to the brain via relay neurons, which are also known as interneurons. They reside within the central nervous system and transmit the signals from sensory neurons to appropriate areas of the brain for processing.
Upon processing the sensory data, the brain forms a motor response which is relayed back towards the muscles in his arms to stop digging. The 'stop digging' response is sent through motor neurons, which transmit the signals from the brain to the muscles in Jeremy's arms, causing him to stop the movement of the spade.

Answer:
Polydactyly is a genetic condition where formation of extra finger or toe takes place.The extra finger or toe is called as supernumerary.
Explanation:
Polydactyly is associated with mutation in genes in their cis position Mutation in Hoxa gene also results in polydactyly.
It is associated with autosomal dominant mutation that occur in single gene.
This condition appears 1 in every 500.This is a common disorder in African black children and is more frequently found in Africans that are living in Eastern and central part.
Polydactyly is mainly affects the right toe or finger.
It is common in men.
The extra digit may be functional or not,partly formed with some bone.
The small water born plants or animals are known as plankton. They can be either phytoplankton or zooplankton.
The relationship between the the distribution of coral polyps and the population density of plankton is that coral polyp depends on the plankton for their nutrition.
Most of the coral polyps like zoanthids depends on phytoplankton and zooplankton for their food(nutritional needs).
They also depend on the bacterioplankton for their food.
