When animals die they decompose and become natural fertilizer plants. Plants depend on animals for nutrients, pollination and seed dispersal.
Explanation:
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.

Explanation:
<em>The chance that a child from two people with sickle cell trait will have normal RBCs remains the same irrespective of the amount of oxygen in the environment.</em> From the cross:
AS x AS
AA AS AS SS
Hence, the chance of having a child with normal RBCs in both high and low-oxygen environments is 1/4 or 25%.
The chance that a child will have sickle cell disease is also 1/4 or 25%.

Answer;
Endocytosis process
The vesicular process involved in the toxin entering the neuron is endocytosis process.
Explanation;
Endocytosis is a vesicular process, that involves capturing a particle or a substance from the outside of a cell by engulfing it with the cell membrane, and bringing it into the cell.
Botulinum toxin binds to the neuronal cell membranes at the nerve terminus and enters the neuron by endocytosis.
