Answer:

B. Don't let the energy into the fridge.

Explanation:

Temperature is actually "heat density." It is proved that warm air contains more heat per gram than cold air. When we open the door, and hot air gets mixed up, we increase the heat density in the refrigerator and decrease it in the room.

Radiation is also a small effect at room temperature. It can glow in the infrared. When warm and cold air is side by side or mixed up, they are dipped in each other's radiation.

Warm air has more heat and therefore glows brighter while cold air gains energy and warms up. It loses more power from radiation and cools. So, if we want to keep our fridge cold, we have to avoid letting heat into the refrigerator.

victus00 [196]

Answer:

Human insulin

Explanation:

The process where by region of a DNA that codes for a particular function is transferred between organisms into cells Is described as gene transfer. This process can be used to enhance the mechanism of producing a gene that is not originally present in such organisms before. Therefore if the gene that code for insulin is inserted into a bacterial vector , the offspring of such bacteria will be able to synthesize insulin in their cell

1. Why does the Elodea cell have chloroplasts but the onion cell does not, even though both are plant cells? Please answer quick
Oksanka [162]
Chloroplasts contain chlorophyll which is what makes plants green. Onions are not green because they do not contain chloroplasts. The reason they do not have chloroplasts is because in the chloroplast, photosynthesis takes place. A key player in the process of photosynthesis is the sun. The onion itself grows underground which means while they grow they do not come into contact with the sun so chloroplasts in an onion is pointless since they can’t undergo photosynthesis. Hope I helped!
