A particular leg bone for dinosaur fossils has a mean length of 60 inches with a standard deviation of 3 inches. What is the len
stepan [7]

The average length of a specific dinosaur leg bone is 60 inches, with a standard variation of 3 inches. If a z-score is 0, then the length is 67.

Divide your data point by your standard error after taking your data point and subtracting the mean from it. How is the z-score determined? Z-scores are calculated using the formula z = (x-)/, where x represents the raw score, the population mean, & the population variation. The z-score is just the raw score less the population mean, split by the population variance, as the calculation demonstrates. You now have your Z-score. For instance, a scoring of 450 would equate a scores of (450-500)/100 (= -50/100 = -0.50 on a scale with a mean of 500 as well as a standard variation of 100, indicating that the scoring is half a variance below the mean.

Are very long apical projections of epithelial plasmalemma that are incapable of movement.
Ronch [10]

Answer;

-Stereocilia

Explanation;

-Stereocilia are not true cilia, they are very long projected microvilli, incapanble of movement on their own, in ear and male reproductive tract.

-Stereocilia are different from cilia, even though they have a similar name. They are more closely related to microvilli, and some may well consider stereocilia to be a variant of microvilli. They share some features of microvilli. However, stereocilia’s distinctive characteristics are their length and lack of motility. Stereocilia are basically apical modifications of the cell.

-Stereocilia are mechanosensing organelles of hair cells, which respond to fluid motion, or changes in fluid pressure in numerous types of animals for various functions, primarily hearing.

The earlier the cell intervenes in the process of protein synthesis, the _______ energy it wastes. Thus, cells will tend to regu
Olenka [21]

Answer: Option D.

Less; at the earliest possible stage.

Explanation:

Protein synthesis refers to the process in which living cells can produce proteins

This occur in two stages;

Transcription and translation.

Transcription refers to transfer of DNA genetic instructional to MRNA in the nucleus of cells.

Translation, after DNA has been transcribed to MRNA, it is then translated to DNA.

When cells intervene in protein synthesis, less energy is used and the cells will regulate the protein synthesis at the earliest possible stage.
