Answer:
Cephalopods
Explanation:
Cephalopods are a group of molluscs that include the pearly chambered Nautilus, squids, and the octopus. They can be divided into three categories: the Nautiloidea (chambered Nautilus), the Ammonoidea (the extinct ammonites), and the Dibranchiata (squids, the extinct belemnites, and octopuses).
The answer to this is C- electromagnetic waves.
Hope that helps :)
Answer:
a. they can fix carbon at the lower CO2 concentrations that develop when the stomata are closed
Explanation:
C4 plants are those that have the capacity to fix CO2 even when a tiny concentration of it is available.
Desert condition is characterized by dryness and strong heat with both condition capable of creating water stress in plant as a result of evapotranspiration. In order to reduce evapotranspiration rate, desert plants (most C4 plants) close their stomata during the day.
<em>Stomata closure limit the diffusion of CO2 into desert plants and the small concentration of CO2 that results is utilized by a special enzyme in the plants.</em>
The correct option is a.
Plant cell walls are rigid membranes on the outermost part of the cell. The cell wall provides a structured shape for the cell, helping the cell retain its form and shape. The cell wall also controls the rate of replication, allowing plant cells to replicate at a much slower rate than animal cells.
Answer:
11. b.
Explanation:
Photosynthesis stores energy in carbohydrates, cellular respiration releases energy from carbohydrates.
Glucose, C₆H₁₂O₆, is a carbohydrate.
Write out the equations:
<u>Photosynthesis</u>
carbon dioxide + water + light energy => oxygen + glucose/sugar
CO₂ + H₂O + light => O₂ + C₆H₁₂O₆
The carbohydrate is stored in the plant until it needs it, like to perform cellular respiration.
<u>Cellular Respiration</u>
oxygen + glucose/sugar => carbon dioxide + water + ATP energy
O₂ + C₆H₁₂O₆ => CO₂ + H₂O + ATP
The carbohydrate is used to make energy. Energy is released from carbohydrates.
Glucose, C₆H₁₂O₆, is a carbohydrate.
Fault in other options:
a. Photosynthesis and cellular respiration both occur in plants. Plants have mitochondria for cellular respiration.
c. Photosynthesis uses carbon dioxide and cellular respiration releases carbon dioxide.
d. Photosynthesis uses carbon dioxide, cellular respiration uses oxygen.
