Describe the function of each organelle.
Answer:
Cytoplasm: Fluid between the cell membrane and the nucleus. helps protect organelles
Nucleus: A part of the cell containing hereditary information and is responsible for growth and reproduction; the "command center" of the cell.
Ribosome: A small particle in the cell that can make proteins.
Endoplasmic Reticulum: A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.
Golgi Apparatus: A cell structure that helps make and package materials to be transported out of the cell or for storage inside the cell.
Lysosome: Cell organelle filled with enzymes needed to break down certain materials in the cell, such as large food particles or old parts of the cell. May be found only in animal cells.
Vacuole: Saclike storage structure in the cell. can store water, nutrients, and even toxic substances.
Mitochondrion: An organelle containing enzymes responsible for producing energy. (Metabolism/respiration)
Chloroplast: An organelle found in the cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy (photosynthesis).
Cell membrane: The thin, flexible barrier around a cell; controls what enters and leaves the cell.
Cell wall: The structure outside of the cell membrane that is used to provide support and protection. Present in plants, algae, fungi, and many prokaryotes.
Answer:
The nucleus directs cell activity.
Ribosomes produce proteins for the cell. These proteins are then moved through the cell by the endoplasmic reticulum.
The Golgi apparatus packages and distributes proteins from the endoplasmic reticulum.
Vacuoles store water, waste products, food, etc.
Lysosomes break down waste material and debris.
Mitochondria break down sugar molecules to supply energy. Similarly, chloroplasts capture the energy from sunlight and convert it into chemical energy.
The cell membrane protects the cell and controls what enters and leaves it. The cell wall supports the cell membrane, maintains the cell’s shape, and protects the cell.
The cytoplasm supports and protects organelles in the cell.

Hemophilia is an X-linked recessive disorder (Xh) that is passed through generations and can be traced by using a pedigree. Based on the pedigree that is shown, which describes John? A)carrier for hemophilia B)expresses hemophilia C)does not have hemophilia D)expresses hemophilia and died of complications
Answer:
C) Does not have hemophilia
Explanation:
When a pedigree is half shaded, the person is a carrier.
When a pedigree is not shaded, the person doesn't express the gene.
When a pedigree is completely shaded, the person is affected.
Square usually is male and circles are usually female.
Since John is the non-shaded square and parent of 4 offspring, he does not have hemophilia. However, his wife is a carrier, and that's how their offspring have hemophilia.

Why don’t populations of organisms that reproduce asexually have the same genetic variation as populations that reproduce sexually
Answer:
Asexual reproducing populations only get their genetics from a single parent, meaning that they all have the exact same DNA/RNA, while sexually reproducing populations have two parents meaning they get genetic code from two parents instead of one, therefore they have more variance. This variance is also the reason sexually reproducing populations are usually harder to wipe out due to variance.
Lipids provide about
kJ/g of energy and are stored in
A. 19, granules
B. 36, triglycerides
C. 38, adipose tissue
D. none of these is correct
Answer:
C. 38, adipose tissue
Explanation:
Lipids/fats are one of the three energy storing biomolecules in living systems; the other two being carbohydrates and proteins. Three of them supply energy when oxidized but the amount of energy differs with lipids providing the most amount of energy.
Lipids provide 9 calories of energy per gram when oxidized, which is about 38Kj/g (where 4.2kJ = 1 calorie). Also, lipids or fats are stored throughout the body, specifically in connective tissues called ADIPOSE TISSUES.

A food handler who fails to report illness to the person in charge could cause a physical contamination?
Answer:
True
Explanation:
Physical contamination are foreign objects such as hair, fingernails, broken glasses , jewelries etc that are mixed with food. Although, it is important for a food handler who realizes that he is sick such as having fever, jaundice,wound while working to report such to his supervisor or manager,who will then take necessary action and to avoid risk of contamination; yet not the only cause of physical food contamination.
Physical contamination does not necessarily have to occur until the food handler is sick. It could be as a result of carelessness or not paying attention enough by the food handler . Physical contamination might not at all times cause injury or illness to the customer, yet such could bring discomfort to a customer who notices foreign objects in his food while eating. To avoid risk of physical food contamination, it is important for food handlers to keep jewelries to a minimum, wash fruits and vegetables thoroughly, wear hear neatly tied back, throw out and replace cracked, chipped, or broken dishware, glassware and equipment amongst others.

Which of the following statements associated with cellulose is false? A) It's a linear polymer of glucose. B) The glycosidic linkage is β(1 → 4). C) Hydrolysis is accomplished enzymatically by cellulase. D) Most animals can easily digest this compound.
Answer:
Most animals can easily digest this compound
Explanation:
Cellulose is a linear polymer of glucose comprising of beta 1,4-glycosidic linkage of glucose molecules; this is where it differs from starch. Cellulose is a polysaccharide made of glucose monomers just like starch. The enzymatic hydrolysis of cellulose is achieved by the enzyme cellulase.
Not all animals can digest cellulose. As a mater of fact, no vertebrate can digest cellulose directly. Many herbivorous animals possess symbiotic bacteria in their gastrointestinal tract which enables the digestion of cellulose. These bacteria possess the requisite enzymes for the digestion of cellulose.

Hypothesize about tumor growth. Scientists have shown that tumor growth is an example of positive feedback loops. Why is tumor growth an example of positive feedback? In your answer elaborate using the following terms stimulus, receptor, control center, effector, response.
Answer:
The connection between cancer cells stimulates uncontrolled proliferation and tumor growth
Explanation:
In the tumor, cancer cells are interconnected by different types of proteins, which may act as receptors or amplify oncogenic signals. For example, in breast cancer, it has been shown that oncogenic cells are often connected through E-cadherin proteins that mediate their adhesion, thereby stimulating the cell movement and invasion (characteristic of tumor metastasis). In this case, E-cadherin membrane proteins function by enhancing effector response in cancer cells. The nucleus acts as the control center of the cell that modulates the expression of tumor suppressor genes in order to inhibit tumor metastasis.
