Biology

Alik [6]3 years ago
6 0

Answer:

Natural Selection

Explanation:

A random genetic mutation gave rise to the dark colored moths. All types of living things have small differences between the individuals in the species. If one of those differences allows the individual to live longer, they will likely have more offspring. As that trait is passed on, the population starts to look more like a successful individual. Over time, the species changes.

Tanzania [10]

Answer:

Photosynthesis produces: <em>glucose </em><em>and </em> O_{2}

                 ...from  CO_{2}, energy (light) and H_{2} O

Respiration produces: energy (ATP),CO_{2}, H_{2} O  

                ....from <em>glucose </em><em>and  </em>O_{2}<em />

<em />

Explanation:

These end products, namely O_{2} and glucose are then used in respiration...

Using energy in the form of solar energy, plants, phytoplankton, algae, and other microorganisms produce chemical energy via photosynthesis. This complex mechanism is central to these species.

They combine light energy from the sun, water, and carbon dioxide.

6CO_{2} + 6H_{2} O + (energy) →C_{6} H_{12} O_{6} + 6O_{2}

In the mechanism of cellular respiration, organisms extract energy from food. Sugars in the form of glucose are broken down into carbon dioxide and water during aerobic respiration in mitochondria to produce energy in the form of ATP (adenosine triphosphate).

<h3>C_{6} H_{12} O_{6} + 6 O_{2}  _{\to \ 6CO_{2} + H_{2} O + energy (ATP)</h3>

The waste products, CO_{2} and H_{2} O,  result from respiration, these are used as reactants in the photosynthetic process. In turn, its products are the reactants O_{2}  and C_{6} H_{12} O_{6} in respiration.

Similarities and differences between arteries and veins
nika2105 [10]

Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation. Arteries and veins are two of the body's main type of blood vessels.
