Answer:
Option-D
Explanation:
A reflex arc is the neuron pathway which is involved in producing the response to reflex action or the immediate response.
The reflex arc pathway involves the sensory neurons, interneurons and the motor neurons.
Although the reflex arc pathway involves the brain later but in producing response the brain is not involved.
The stimuli are perceived by the spinal cord but not the brain therefore the selected option is correct.
Thus, option-D is correct.
Hello,
Here is your answer:
The proper answer tot his question is A "cross pollinated".
Your answer is A.
If you need anymore help feel free to ask me!
Hope this helps!
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.

I would go with hypothesis because I never heard any of the other answers in Bio and a hypothesis is an educated guess so it means what you already know and it’s an observation (I hope this helped!!)
Answer: Oviduct
Explanation:
The oviduct also known as the Fallopian tube is a long narrow tube with funnel shaped opening which receives eggs (Ova) released by the ovary. So, the oviduct link the ovary with the uterus, and it is the site where sperm released from the male meet the egg to fertilize it into zygote.
Thus, oviduct is the answer
