The option, epineurium bundles fascicles into nerve, is the correct response.
The outermost layer of connective tissue that surrounds the entire nerve is known as the epineurium. All of the nerve fascicles and any blood arteries that supply the nerve are enclosed by this dense, wavy connective tissue. These blood arteries' more delicate branches enter the perineurium. In addition to the blood vessels that nourish the nerve, lymphocytes and fibroblasts are also present and help to produce the collagen fibres that make up the epineurium's support structure. Lymphocytes and fibroblasts are essential for maintaining and repairing the surrounding tissues in addition to supporting the structure.
Two layers of the spinal meninges, the arachnoid and the dura, invaginate the spinal nerve as it exits the vertebral canal through an intervertebral foramen to create a dural sleeve of connective tissue, or the epineurium. This sleeve's external epineurium, which is located on the outside, allows for longitudinal nerve excursion and longitudinal stress absorption.

C. 500 million years. D. younger than 400 million years.
Answers
Answer:
B. between 400 million and 500 million years
Explanation:
Process of elimination
Answer: Answer is B, Younger than 400 million years
Explanation:
The age of rock layers in a stack reflects the order in which they were deposited—the lower layers were laid down first, and then the upper layers were laid on top of them. So, the lower layers and fossils they contain are older than the upper layers and fossils. This is known as the principle of superposition.
In this example, Layer 1 was deposited first, then Layer 2, Layer 3, Layer 4, and Layer 5. Layer 1 is the oldest, and the layers get younger as you move up through the stack.
If the age of a particular layer is known, then the relative age of other layers can be determined. In this example, Layer 4 is 400 million years old. This means that the layer above it is younger than 400 million years and the layers below it are older than 400 million years. Layer 1 is 500 million years old. This means that layers above it are younger than 500 million years.
Layer 5 is above Layer 4, so it must be younger than 400 million years.

John had a science fair project that he needed to do. He wanted to test the effects that organic and chemical fertilizers had on plant growth. John predicted that the organic fertilizer would make the plants grow taller. He used three pots, three of the same type of seed, soil, organic fertilizer, chemical fertilizer, water, and a ruler. John put soil in the pots. He added chemical fertilizer to the first pot, organic fertilizer in the second pot, and no fertilizer in the third pot. He then planted one seed in each pot. John had to water the pots daily. He also checked for growth and took measurements for a period of 10 days. He measured the height of the plants.

Part 2: [Insert a line graph representing the height of each plant over the ten days. Title the graph "Plant Growth Over 10 Days."]
Conclusion:
The analysis of the data shows that the chemical fertilizer worked best, as the plant treated with chemical fertilizer grew to 5.2 cm in height, while the organic fertilizer plant grew to 3.8 cm. The plant with no fertilizer did not grow well, only reaching 0.2 cm in height over the ten days.
John's hypothesis that the organic fertilizer would make the plants grow taller was incorrect. The chemical fertilizer had a greater impact on plant growth than the organic fertilizer. To further test this investigation, John could use a wider variety of plants, different types or concentrations of fertilizers, or extend the duration of the experiment.
Questions:
1. A scientific experiment is reliable when it is:
- **Replicable**: The experiment can be reproduced by other researchers with the same results.
- **Controlled**: Variables are carefully controlled to reduce the impact of external factors on the experiment's outcome.
- **Valid**: The experiment measures what it is intended to measure, and the results accurately reflect the effect of the variables being tested.
2. Using peer-reviewed evidence during a scientific investigation is crucial because:
- It ensures the information is accurate and reliable, as it has been reviewed and approved by experts in the field.
- It helps maintain high standards of research and reduces the likelihood of using incorrect or misleading information.
- It promotes the sharing of knowledge among researchers and encourages collaboration, which can lead to more reliable and effective scientific investigations.
Conclusion Questions:
John's hypothesis was incorrect because the data showed that the chemical fertilizer made the plants grow taller than the organic fertilizer.
Based on the data in the table, the chemical fertilizer worked the best, as it led to the greatest increase in plant height (5.2 cm) after ten days.
The plant that did not grow well was the one with no fertilizer, as it only reached 0.2 cm in height after ten days.
Analysis Questions:
To improve this experiment, John could:
- Test different types or concentrations of fertilizers to see how they affect plant growth.
- Use a larger sample size of plants for each fertilizer type to account for any variability within each group.
- Extend the duration of the experiment to observe the long-term effects of the fertilizers on plant growth.
This experiment can be beneficial in real-world applications by helping farmers, gardeners, and agricultural companies determine which type of fertilizer is most effective for promoting plant growth. By understanding the impact of chemical and organic fertilizers on plant growth, they can make informed decisions about the best fertilization practices for their crops and gardens.

Polydactyly is a rare autosomal dominant trait that is 80% penetrant. What is the chance that a child born to an affected father and a normal mother will have the disorder
Answers
The question is incomplete, below is the complete question.
Polydactyly is a rare autosomal dominant trait that is 80% penetrant. What is the chance that a child born to an affected father and a normal mother will have the disorder?
Assume the paternal grandfather is normal.
I will use P to encode polydactyl as it is dominant and use p allele to encode normal phenotype
P= Polydactyl
p= Normal
From what is given in the question,the paternal grandfather is normal and that means that the father of the child receives one wild type allele from the paternal grandfather, however,the father is affected with the disease,hence the genotype is A a but the mother being normal will have the genotype of aa.
That is Parents;
Father Aa × Mother aa
Gametes a a A Aa ( P ) Aa ( P )
a aa ( p ) aa ( p )
So if it is 100% penetrant, that implies that the chances of the affected child is;
(2/4 ) ×100=50%
However, only 80% penetrant is given here,so that is why the chances of the affected is then ; (50/100) ×(80/100) ×100= 40%
That means the affected child chances are 40%.
