Why would you expect to find more evidence of diatoms than green algae in a sample of ocean floor sediment?
Diatoms are a major group of phytoplankton that thrive in marine environments and are highly productive, contributing significantly to oceanic primary production. Their silica-based cell walls (frustules) are more resistant to degradation and can persist in sediments for long periods, leading to a greater accumulation of diatom remains. In contrast, green algae are more commonly found in freshwater environments and, when present in marine settings, their organic structures are less durable, making them less likely to be preserved in sediment over time. As a result, ocean floor sediments typically exhibit a higher abundance of diatom evidence compared to green algae.

What causes dirt in well water?
It comes from the ground, what do you expect. If the dirt is significant you may need a sediment or sand filter. I would definitely take a sample for analysis if you are drinking it.It comes from the ground, what do you expect. If the dirt is significant you may need a sediment or sand filter.

Why do you sample forensic evidence?
Forensic evidence is not 'sampled,' it is ANALYZED, by taking a 'sample' of it and conducting laboratory or or other technical tests or analyses of it.
What would you expect to see in a blood sample of a person who has drowned in salt water?
In the blood sample of a person who has drowned in salt water, you may expect to see increased levels of sodium and chloride ions due to the ingestion of salt water. Additionally, there may be evidence of pulmonary edema or fluid in the lungs due to salt water aspiration.
Why do we centrifuge a urine sample when performing a complete urinalysis?
We centrifuge a urine sample to separate the liquid portion (urine) from any solid components (sediment). This helps to examine the urine sediment under a microscope to check for cells, crystals, bacteria, and other particles that may indicate a health condition.
If you examined a sample of sea water under a microscope you might observe tiny shelled organisms often used to add luster to fingernail polish or paint What group would you be observing?
Diatoms
What causes brown looking water?
Can be iron or other sediment or tannin. If it persists take a sample for analysis and then you will know if and what kind of filter to get.
What would you expect to see in elevated numbers in a peripheral blood sample after donating a pint of blood?
erythrocytes
What does it mean to say that the sample variance provides an unbiased estimate of the population variance?
It means you can take a measure of the variance of the sample and expect that result to be consistent for the entire population, and the sample is a valid representation for/of the population and does not influence that measure of the population.
Where would one go to get a sample driving permit test?
By visiting the DMV you can take a look at different sample tests. Before the actual test is taken it is best to look through the sample tests first to unsure that you know what you can expect.
Learn What To Expect With A Sample Cable Bill?
Signing up for cable for the first time can make budgeting for the new bill difficult, since the total rarely comes out to what you expect. Some companies and websites can provide a sample bill so you can start budgeting in advance. Before you sign up for cable service, ask the company you are working with to provide you with a sample cable bill for your particular plan so you know what extra fees and unexpected charges may show up on your account. Comparing a sample bill to the amount you expect to spend is a great way to protect yourself from unnecessary expenses.
How many integers between 1 to 25 would you expect to appear in a sample of 80 trials?
A sample of 5 integers selected is shown. Does this sample represent the general rule for picking an integer from 1 to 25 in the population of integers from 1 to 1,000? Explain.
