The immune system is the body's defense against infectious organisms and other invaders. Your immune system works by recognizing the difference between your body's cells and alien cells, allowing it to destroy anything that could be potentially harmful. Active and passive immunity play an important role in keeping you healthy.

What is the difference between passive and active immunity? (SC.912. L.14.52)

A. Naturally acquired active immunity occurs when the person is exposed to a live pathogen, develops the disease, and becomes immune while naturally acquired passive immunity occurs during pregnancy, in which certain antibodies are passed from the maternal into the fetal bloodstream

B. Both passive and active immunity are interchangeable

C. Passive and active immunity are both 1st line of defenses

D. Passive immunity occurs when a person is exposed to a virus and active immunity occurs when the immunity is passed on through breast feeding

Explanation:

The agricultural biotech company you work for has tasked you and your co-worker to genetically engineer a plant that produces more oxygen that at the same time also produces more sugar. Your co-worker states that this is impossible.

Questions: Based on what you've learned how would you respond to your co-worker?
What is your opinion of the ethics of manipulating crop plants in such a way?

Answers

Answer:

- The co-worker is wrong, it is indeed possible

- Genetically engineered plants may represent a milestone to alleviate hunger in the world

Explanation:

During photosynthesis, plants use carbon dioxide (CO2) from the air and water (H2O) from soil and rain in order to produce oxygen and glucose, which is a sugar (molecular formula C6​H12​O6). Subsequently, plants release oxygen into the air and store energy (and carbon compounds) in the form of glucose. In consequence, an increase in the photosynthetic rate is directly associated with an increase in both the production of oxygen and glucose. On the other hand, genetically engineered plants can help to reduce hunger in developing countries. In consequence, it is acceptable to develop genetically modified plants as long as contemplating regulatory measures aimed at producing safe products (for example, by avoiding the introduction of genetically engineered genes into wild crop populations).

Which of the following irrigation methods is most likely to result in salinization of the soil, especially if the agricultural fields are located in a warm climate with consistent sunlight
A Spray irrigation
Furrow irrigation
Flood irrigation
Drip Irrigation

Answers

Answer: Furrow Irrigation (B)

Explanation:

Furrow irrigation

Salinization of the SoilThe accumulation of water-soluble salts in the soil is known as salinization. Excess salts inhibit crop growth by decreasing their ability to absorb water, making salinization a resource concern.Surface irrigation in which trenches or "furrows" are created between crop rows in a field is known as furrow irrigation. Furrow irrigation is done by laying down short parallel channels down the length of the field in the direction of the predominant slope.Furrow irrigation is most likely to result in salinization of the soil, especially if the agricultural fields are located in a warm climate with consistent sunlight
