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.
Answer:
Non-vascular plants are plants without xylem and phloem. The parts of the plant that transport nutrients/sugars(phloem) and water/ minerals(xylem)
Seedless vascular plants have xylem and phloem, but only make leaves, not flowers or seed
Explanation:
Cold air usually pushes warm air because cold air has a HIGHER DENSITY
It is C my brother. i legit just took the quiz rn! good luck. God bless
You did not included your list of selections. Some general properties ascribed to DNA are storage and expression of information and variables through mutations. Replication, Transcription, Translation and Mutagenesis are the major functions of DNA in a cell. DNA nucleotides contain deoxyribose. DNA is double-stranded in the conservative mode, the original double Helix remains a complete unit and the new DNA double Helix is produced as a single unit. In the double=stranded DNA, Hydrogen bonds hold one complimentary strand to the other.
Hope this helps, I love Science.
