Question

Complete a brief paragraph on each of the assigned topics below. All work should be in sentence/paragraph form, and in your own words (do not copy and paste from our power points or other sources). You should need no other sources than the course power points and your biology textbook. Please indicate which textbook, if any, you have used.   

Science, Life and Homeostasis: Describe the characteristics that all living things share?

Biological Molecules: Describe the general structure and function of nucleic acids.

Cell Anatomy: Describe the four things all cells have in common.

Cell Membranes: Describe the ways in which proteins are involved in transport across cell membranes.

Metabolism: Compare and contrast the light reactions of photosynthesis to the electron transport chain of cellular respiration.

Mitosis and Meiosis: Briefly describe the four ways that mitosis and meiosis differ from each other.

Transcription and Translation of the Genetic Code: Describe the different types of RNA at work in the cell and their roles in the transcription and translation of the genetic code.

Musculoskeletal system: Describe the four steps in the cross-bridge formation of a muscle contraction.

Sensory and the Nervous System: Describe how an action potential occurs.

Circulatory and Respiratory System: Describe what is happening in your thoracic cavity when you breathe in and out.

The Endocrine System: How do the thyroid and parathyroid work together to control calcium levels in the blood?

The Immune System: Compare and contrast the innate immune system and the adaptive immune system.

Excretion and Osmolarity: Describe how the kidney’s counter-current multiplier system works.

Digestion: What is the process for digesting lipids?

Reproduction: What happens during ovulation?

Microorganisms: Compare and contrast Gram-negative and Gram-positive bacteria in terms of their cell wall.

Explanation / Answer

ANS- Living things made up of cell so they can grow. Prokaryotes are unicellular and they have everything for the survival and eukaryotes are multicellular which makes tissue, organ, organ system and organism.

All living things have sense and respond to change for the homeostasis and environment.

Reproduction occurred by the asexually or sexually,Asexual reproduction need one parent and sexually reproduction need two parents (male and female )

Living things use the energy for the function by the cell respiration or photosynthesis.

They have genetic material called DNA , a important characteristic of life.

2 ans-Nucleic acid DNA and RNA both contains the pyrimidine (Cytosine, thymine in DNA and uracil in RNA) and purines (adenine and guanine).hey are made up of three units-a five carbon sugar, a nitrogen base and a phosphate group. Nucleic acids involved in the storage and transmitted the genetic code from parents to child and found in the nucleus of the cell.DNA and RNA both participate in protein synthesis in the cell.

3 ans-Cytoplasm- jelly-like substance, found in the cell and enclosed by the cell membrane and all the cell organelles are embedded in the cytoplasm, a place where the all cell process occurred for example-photosynthesis, respiration.

Cell membrane-all cells have a selective permeable cell membrane which is made up of phospholipids and allows the selected materials in and out of the cell by the different mechanism.

DNA-genetic material DNA and RNA

Ribosomes-consist of protein complex and and involve in the protein synthesis.
