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.
There is 23 chromosomes in one gamete
<span>The one thing that is not true of water is that D. it is a poor solvent.
Water is known as the universal solvent. Water will dissolve more things than any other liquid in the world. Both the chemical and the physical attributes makes water the universal solvent. The molecules in water have a polar arrangement of the hydrogen and oxygen molecules. One of the sides, hydrogen, has a positive electrical charge while the oxygen side has a negative side. The answer is D.</span>
Answer:
The answer is the cerebrum.
Explanation:
The brain consists of the following parts; the cerebrum, cerebellum and the brainstem.
The cerebrum is the largest part of the brain located in front. It has two large hemispheres joined by the corpus callosum. The cerebrum has four lobes including frontal, parietal, temporal, and occipital lobes. Functions include: initiation and coordination of movement, memory, touch, hearing etc
The brainstem is composed of the midbrain, the pons, and the medulla. Controls involuntary muscle movements, cardiac function, sneezing etc.
The cerebellum located at the back of the head has two hemispheres. It is controls voluntary muscle movement, posture, balance and equilibrium.
If the body loses a substantial amount of fluids and salts and they are not quickly replaced; for example: by drinking, the body starts to "dry up" or get dehydrated. Severe dehydration can cause death. The usual causes of dehydration are a lot of diarrhoea and vomiting
