We cannot visualize the organs or tissues inside of our body, but a biopsy helps in making a diagnosis by providing a piece of tissue for examination. Biopsies are often associated with cancer, but they can be used to diagnose other conditions and to see how far a disease has progressed.
Inches or centimeters, because it is not that big so you would not use anything else because its not logical.
<span>Glial cells in the white matter help promote communication between the nerve impulses in the gray matter. They differ because in the peripheral nervous system there is more of a fatty substance that acts as a cushion between the impulses, which is a little different than helping the nerve impulses along intentionally. The cushioning may aid in transmission indirectly, but serves as more of a safety zone.</span>
Answer:
Other factors could affect the reason the seed didn't germinate because under suitable conditions depending on the variety it should germinate within 5 to 10 days from planting. However, the most likely reason it didn't germinate must be the Temperature.
Explanation:
From the question above, the farmer lives in Minnesota and she planted between March and May, meaning the temperature was way cold which is not suitable for tomato. One other valuable point was she planting outdoor which could also affect the performance of the tomato seedlings. Planting in early spring doesn't necessarily mean bad as some seeds might thrive under conditions explained above. For tomato, depending on temperature because too high temperatures could also affect the viability of the seeds. In Minnesota in early spring, it would have been better if she planted indoors to raise the temperature before transplanting as a balanced night temperature is also important for the seed viability.
Some other factors to be considered for seeds to germinate:
1. Water
2. Type of the soil
3. Seed depth in the soil
4. Nature of seed coat
5. Oxygen
6. Light
Explanation:
According to Hardy Weinberg, the gene and allele frequencies for a population should ideally remain unchanged (stable) over generations. However, assumptions by Hardy Weinberg for a population to be at equilibrium can hardly be held true, naturally. This is because;
- There is always some form of immigration and emigration within a population
- A population can hardly be infinitely large
- Mutations do occur in populations
- In some occasions, mating within the population may not be random
- Natural selection is always at play within populations
