[Bio1 and Bio3] End of quarter reflections for the second quarter and announcements

Sorry for the delay! Been experiencing problems with gmail account. Thanks for your patience and understanding. It has really meant a lot throughout this difficult recovery period. The form will be online until Nov2, 12MN. The sooner you submit, the sooner you can get your partial grades through the email addresses provided.

Final deadline for unsubmitted SWs or resubmissions is Oct 30, 430PM at the Bio Unit. Please put in my pigeonhole.

Bio1 post quarter exams (for those who missed long tests) will be tomorrow, Tuesday, October 28. 4pm at SHB 111.

For the Bio1 portfolio, final deadline is Nov 3, 12 NN at the Bio unit. For those submitting digital files, you may email them to dtcrisologo@pshs.edu.ph. Please use “Bio1 portfolio submission” as your subject line and use your section, CN and surname as the filename (e.g. K18-Crisologo.pdf). As with previous Bio1 portfolio, please present in any creative manner what you’ve learned/appreciated about any of our lessons this quarter. You will be graded on

  1. Content – accuracy, completeness (30%)
  2. Creativity – aesthetics, design (30%)
  3. Relevance – related to topics taken up this quarter (10%)
  4. Personal input – personal touch (30%)

[Bio1] Guide Questions for the 2nd Quarter Periodic Exam

Perio Guide Questions (if you are able to answer these, then you will do well in the Periodic Exam)

Characteristics and Evolution of Eukaryotes
1. How are prokaryotes different from eukaryotes?
2. How did eukaryotes evolve from prokaryotic ancestors (endosymbiont theory)?

Protists
3. What are protists?
4. How would you differentiate between plant, animal, and fungus-like protists?

The Evolution of Multicellularity and the Volvocine Series
5. How did multicellular forms evolve from unicellular ones (Volvocine series)?
6. What are some trends in the evolution of multicellularity?
7. What are the advantages/disadvantages of multicellularity?

Plant and Animal Tissues
8. What are tissues?
9. Differentiate between plant and animal tissues based on structure/location/function.

Bioenergetics and Digestion
10. Define: metabolism, anabolism, and catabolism.
11. Enumerate the four processes that must be accomplished during digestion.
12. Describe the following digestive processes in organisms with: a) intracellular digestion only, b) extracellular digestion only, c) incomplete digestive systems, and d) complete digestive system. Name the types of animals associated with the given type of system.
13. Enumerate some observable trends in the evolution of digestive systems in vertebrates and in mammals.
14. Trace the pathway of food and the different enzymes it encounters in the human digestive tract.
15. Describe what happens to food in the small and large intestines.

Transport and Circulation
16. Describe the structure of the cell membrane. How does its structure allow it to become selectively permeable to different types of materials?
17. Describe the different processes of cellular transport in terms of energy required, substances involved, direction of flow of substances.
18. Define isotonic, hypotonic, and hypertonic solutions. What happens to an animal cell when immersed in this kind of medium? What happens to a plant cell?
19. Differentiate between phloem and xylem in terms of structure and function.
20. How are water and dissolved minerals transported into the roots? What role does the Casparian strip play in the transport of materials into the root xylem?
21. Describe the root pressure transpiration-cohesion-tension mechanism by defining the associated terms and explaining how they work together in allowing water to rise in the plant.
22. Describe the bulk or pressure flow mechanism by defining the associated terms and explaining it works to transport phloem sap from sources to sinks.

[Bio3] (Pairwork) Lib activity for Truth and Electron

Answer the following questions on 1 whole sheet of paper. This will be submitted first thing next period. You may use phrases, bullet points, diagrams, etc. to answer the questions.

  1. View Link 1Link 2, Link3, and describe how DNA and proteins are organized into chromosomes. Familiarize yourself with structures and terms (histones, double helix, chromatin, nucleosome, chromosome, etc.).
  2. View Link 3 and create a flowchart showing how karyotyping is performed.
  3. View Link 4 and draw examples of chromosomes undergoing deletion, duplication, inversion, translocation, and reciprocal translocations. Give examples of syndromes that are caused by changes in chromosome structure.
  4. View Link 5 and describe how trisomy and monosomy can occur. Give examples of syndromes that are caused by aneuploidy.
