In a diploid cell in which 2n = 14, how many telomeres are there in each of the following phases of the cell cycle? (a) G1 (b) G2 (c) prophase of mitosis (d) telophase of mitosis

A helicopter is flying horizontally at 8.0 m/s and an altitude of 18 m when a package of emergency medical supplies is ejected horizontally backward with a speed of 12 m/s relative to the helicopter. Ignoring air resistance, what is the horizontal distance between the package and the helicopter when the package hits the ground?

Draw the phases of mitosis for a cell that contains four chromosomes as its diploid or 2n number.

The power, P, dissipated when a 9-volt battery is put across a resistance of R ohms is given by $P = \frac { 81 } { R }.$

Consider the following segment of DNA, which is part of a much longer molecule constituting a chromosome:

$$\text { 5'....ATTCGTACGATCGACTGACTGACAGTC...3' }$$

$$\text { 3'... TAAGCATGCTAGCTGACTGACTGTCAG....5' }$$

If the DNA polymerase starts replicating this segment from the right, a. which will be the template for the leading strand? b. Draw the molecule when the DNA polymerase is halfway along this segment. c. Draw the two complete daughter molecules. d. Is your diagram in part b compatible with bidirectional replication from a single origin, the usual mode of replication?

Graph the function $y=-\frac{5}{2}\sin\left(\frac{3}{2}x\right)$.

Which of the following is not a key property of hereditary material? a. It must be capable of being copied accurately. b. It must encode the information necessary to form proteins and complex structures. c. It must occasionally mutate. d. It must be able to adapt itself to each of the body’s tissues.

Determine the phases of mitosis, and briefly discuss the events that occur during each phase.

Graph each quadratic function.

$$f(x)=-4x^2$$

Describe the events that occur during the phases of mitosis.

Do bacteria require telomerase? Explain why or why not.

A strain of bacteria possesses a temperature-sensitive mutation in the gene that encodes the sigma factor. The mutant bacteria produce a sigma factor that is unable to bind to RNA polymerase at elevated temperatures. What effect will this mutation have on the process of transcription when the bacteria are raised at elevated temperatures?

What are the two major periods that comprise the life cycle of the cell?

The quick ratio Q of a business is related to its current assets A, its current inventory I, and its current liabilities L, by $Q = \frac { A - I } { L }$ Assuming that Q = 37,000 , L = $1500, and I =$3200, find the current assets.
