<span>According to the Centers for Disease Control and Prevention (CDC), diseases caused by smoking kill more than 480,000 people in the U.S. each year. In fact, smoking is directly responsible for almost 90% of lung cancer and COPD deaths. Even with antismoking campaigns and health warnings, many people continue to smoke or start to smoke every year. About 8% of kids under the age of 18 years are current tobacco users.</span>

What happens when ATP is converted to ADP
Kaylis [27]

The electrons in these bonds carry energy. Within the power plants of the cell (mitochondria), energy is used to add one molecule of inorganic phosphate (P) to a molecule of adenosine diphosphate (ADP). The amount of energy stored is about 7,300 calories for every mole of ATP formed.

Why does darkness affect the light-independent reactions of photosynthesis?
notsponge [240]

Answer:

The correct answer would be Light independent reactions require the energy gathered in the thylakoids.

Photosynthesis can divided into two sub-processes or reactions:

Light-dependent reaction: It converts solar energy into chemical energy that is, ATP (adenosine triphosphate) and NADPH with the help of photolysisis of water. It takes place in thyllakoid membrane of the chloroplast.

Light-independent reaction: It fixes carbon obtained from carbon dioxide into the food or glucose with the help of enzyme RuBisCO (Ribulose-1,5-bisphosphate carboxylase/oxygenase).

It takes place in the stroma of the chloroplast and does not require the involvement of light however, it requires the products (ATP and NADPH) of the light reaction.

Fixation of 1 molecule of glucose requires 6 molecules of carbon dioxide, 9 molecules of ATP and 6 molecules of NADPH.

So, darkness indirectly affects the light-independent reaction.

Flowers of orchid species Ophrys bombyliflora look and smell like female bumblebees. This attracts the male bumblebees flying ne
balandron [24]
I would say A) Coevolution because the two species would evolve in response to one another. Flowers and their pollinators must evolve together. For example, if the flower has a mutation that no longer attracts the bumblebees, it will not reproduce. Then the hummingbird would have to find a new food source.
