There is consensus among scientists that humans are causing the climate to warm. Why might this warming impact biological produc

tivity in the deepest ocean zones? Use the figure below to aid in answering this question.

A. Warming may slow or halt the formation of cold dense water in polar regions, reducing the delivery of carbon dioxide to depth, and slowing aerobic cellular respiration and productivity in deeper zones.
B.Warming may slow or halt the formation of cold dense water in polar regions, reducing the delivery of nutrients to depth, and thereby reducing productivity in deeper zones.
C. Warming may slow or halt the formation of cold dense water in polar regions, reducing the delivery of phytoplankton to depth, and thereby reducing productivity in deeper zones.
D. Warming may slow or halt the formation of cold dense water in polar regions, reducing the delivery of well oxygenated water to depth, and thereby slowing aerobic cellular respiration and productivity in deeper zones.

The answer is: "<span>Warming may slow or halt the formation of cold dense water in polar regions, reducing the delivery of nutrients to depth, and thereby reducing productivity in deeper zones."

Global warming is caused by the accumulation of greenhouse gases in the atmosphere primarily by human activity. These increases the temperature in the polar regions will warm the water (and subsequently halting the formation of cold water). The melting of ice will release nutrients and stimulate the growth of phytoplanktons, and these organisms will compete with the nutrition in the deeper zones (the phytoplanktons and algae will reduce the available nutrients for deep sea creatures) and therefore decreasing the productivity.</span>

Clouds can begin to form at which point?
Mademuasel [1]
<span>Clouds and fog begin to from at the condensation process of the water cycle. Condensation is the process wherein water vapor changes into liquid water which is responsible for the formation of clouds. clouds produces precipitation, which is an important part of the water cycle wherein water returns to the earth's surface.</span>

If a person uses up his or her reserve supply of glycogen and still does not eat, sugar comes from the?
Anvisha [2.4K]

If a person uses up his or her reserve supply of glycogen and still does not eat, sugar comes from the muscle.

Although only liver glycogen directly contributes to the release of glucose into circulation, maintaining a healthy blood glucose concentration is one of the glycogen's key functions. Since skeletal muscles lack glucose 6-phosphatase, they are unable to release glucose, and muscle glycogen primarily serves as a local energy source for activity rather than a source of fuel to keep blood glucose levels stable while fasting.

In fact, the breakdown of muscle glycogen into lactate allows for its delivery to the liver, where it participates in the maintenance of euglycemia through the process of gluconeogenesis (Cori cycle).

Which of the following adaptations enables deciduous trees to produce more food?
krok68 [10]

Answer:

Thick bark is the adaptation that enables deciduous trees to produce more food.  

Deciduous trees are trees such as oak, maple, and hickory trees which lose their leaves for part of the year. Bark is an important part of a tree that protects the tree. The thick bark of the deciduous trees is composed of many layers and it provides the tree with the necessary nutrients and moisture it needs for its growth.
