Females are born with all the eggs they will ever carry (i.e. no more eggs are produced). I know sperm is continuously produced, but are they produced from a fixed supply?

My real question is that sperm is produced from spermatogonia (steps skipped), which are produced from primordial germ cells. Do you produce any more primordial germ cells after birth?

Phytochromes are light receptors in plants that absorb mainly red light and regulates plant response to light such as flowering. Describe the physiological mechanism in long-day and short-day plants that could induce flowering. In your opinion, how root cells able to respond to light? 

In your assigned readings, you learned how cells utilize energy. Discuss the importance of electrons in the transfer of energy in living systems. Be sure to use a specific example in your discussion.

Be sure to use in text citation and provide references for your sources. While not required for this discussion, you may use outside resources. Any materials cited in this course should be referenced using the APA style guidelines

The composition of PBS is 0.137M NaCl, 0.012M Phosphate, 0.0027M KCl, pH 7.4. Below is the protocol to make 1 litre of 10x concentrate PBS.

Combine the following:

• 80g NaCl
•  2g KCl
•  14.4g Na₂HPO₄ (dibasic anhydrous)
•  2.4g KH₂PO₄ (monobasic anhydrous)
• 800mL distilled H₂O 

1. Adjust pH to 7.4 with HCl
2. Add H₂O to 1L
3. Autoclave for 20 minutes on liquid cycle. Store at room temperature.

Which ions are being produced by this process, assuming that each of the chemical compounds dissociate into their constituent parts once they are dissolved in water?

Explain the significance φ, ψ contour diagram in proteins and explore how is it interpreted? 

 A monoclonal antibody, specific for a virus, was treated with an enzyme to break the bonds between the variable and constant regions.

The separated variable and constant regions were then added to cells infected with the virus.

Which statements are correct?                                  

1 The constant regions would bind to different parts of the virus antigens.

2 The viruses could be engulfed by phagocytes if they were present.

3 The variable regions would all bind to the same part of the virus antigens.
