Due to mutation and reproduction as well as ability of some organisms to survive, thrive and reproduce brought about changes in allele frequency as seen in the changes occurring at Locus 1048 and 1166.
<h3>Allele and allele frequency </h3>
- An allele is one of an alternate form of a gene.
- Allele frequency is the percentages of each of the different alleles of a particular gene in a population.
Changes in allele frequency that occur over time because of one or more evolutionary factors such as:
- genetic drift,
- gene flow,
- mutation,
- non-random mating,
- selection, etc.
The change in allele in the sea star wasting disease was due to genetic drift which are random change in allele frequencies that occurs in small populations occurring due to such factors as disease.
<h3>Evidence of allele frequency change in sea star wasting disease</h3>
1. Mutation and reproduction results in a variety of genes passed on and carries by individuals of a population.
- The changes that occcured at gene Locus 1048 and 1166 due to mutation helped the post-SSWD starfish to survive and reproduce giving rise to offspring with those changes.
2. Organisms who can survive, thrive, and reproduce will increase in number.
The about 20% post-SSWD starfish that survived due to the change in their allele were able to survive and reproduce rapidly giving rise to offspring such that the individuals in the population have almost risen to pre-SSWD numbers.
Therefore, due to mutation and reproduction as well as ability of some organisms to survive, thrive and reproduce brought about changes in allele frequency as seen in the changes occurring at Locus 1048 and 1166.

Answer:
Nervous system
Explanation:
The nervous system consists of the the brain and the nerves and the damage was done to the nerves that run all the way down his leg.
Answer:
Green algae is divided into chlorophyte and chlorophyte. It possess chlorophyll a and b.
Bryophytes includes the liverworts, mosses and hornworts. It is know tracheaophytes I.e. is not vascular without extensive transport system, it needs water to reproduce sexually. It's Gametophyte is dominant and stomata are absent. (Hornworts possess stomata; it's related to tracheaophytes.
Ferns have vascular tissue, xylem and pholem, stem, root, leaves, dominant sporophyte. It's sporophyte possess rhizomes and fronds plus sporingia aldo called sori. Ferns are seedless vascular plants.
Gymnosperms includes the conifers, cycad e.t.c. It has its ovules resting on a scale. The ovules later develop into the seed. These seeds are naked as there are not enclosed in the chambers.
Angiosperms have flowers and fruits and show diuble fertilization. This is a huge clade that consists of all flowering plants. Unlike Gymnosperms
They develop enclosed in chambers known as ovaries.
The answer is B.
These elements are among the most important elements in life. Most of these elements are also non-metals. Elements life sulfur and nitrogen combine with carbohydrates to form among acids rings like cysteine. Carbohydrates combine with phosphorus to form molecules such as the DNA backbone chain.
