The factor that would least affect photosynthesis is Nitrates in the soil.
Photosynthesis is the process by which plant make their own food by utilizing energy from sunlight, water and carbon dioxide. The limiting factors that affect photosynthesis are the light intensity, carbon dioxide concentration, temperature and water. Without enough light, a plant cannot photosynthesize very quickly, even if there is plenty of water and carbon dioxide.
Answer:
n stage 13, all four limb buds are present. In stage 13, the upper limb buds resemble flippers. In stage 23, the upper limb shows well-formed arm, elbow, wrist, and fingers. In stage 23, the lower limb shows well-formed toes, feet, and knees.
Explanation:
It should be 18 because:
100 x 2 = 200
200 + 70 = 270
360 - 270 = 90
90/5 = 18
So x = 18
The parts of the amniotic reptile egg include the amniotic fluid, the albumen, and the shell.
<h3>Parts of an amniotic reptile's egg</h3>
The various parts of amniotic reptile's eggs include:
- The external shell which serves as a protective layer
- The yolk which supplies energy to the embryo
- The albumen supplies the embryo with water and proteins
- The extra-embryonic membranes - the chorion, the allantois, and the amnion.
The chorion serves as a channel for gaseous exchange between the embryo and the environment.
The allantois partially functions as waste manager and in respiration. It stores nitrogenous wastes and gets rid of them as well as participates in gaseous exchange along with the chorion.
The amnion protects the embryo against mechanical shocks. It also protects the developing embryo from being dehydrated.
In other words, the 3 extra-embryonic membranes protect, facilitate gaseous exchange, and ensure that wastes are properly disposed of.
