The correct answer is gases oxygen and carbon dioxide, which diffuse freely across the shell of an egg.
The four specialized membranes of the amniotic egg are amnion, chorion, yolk sac, and allantois. The chorion and the allantois exchange gases between the embryo and the air. Oxygen and carbon dioxide diffuse freely across the shell.
An eggshell refers to the outer covering of a hard-shelled egg and of some kinds of eggs with soft outer coats. The shells of the amniotic eggs are calcareous, formed of calcium carbonate.
The new root cells come from the root of the plants that start out with indistinguishable cells as the new plant is emerging, and those cells grow and differentiate into more specialized cell types. The root, cut in a cross-section, reveals several different specialized layers with different kinds of cells.
behind the root cap is the answer
The outer covering of a reptiles egg is hard to protect it from harm while growing. :P
I hope this helped :D
Photosynthesis is a term used to describe a process that combines two other words. This is the method that plants employ to harness solar energy. The words "photo" and "synthesis" both refer to the use of light.
The process by which plants, algae, and some microorganisms convert sunlight, carbon dioxide (CO₂), and water into food (sugars), oxygen, and other compounds is known as photosynthesis.
Chloroplasts, a type of plastid (an organelle with a membrane) that is typically found in plant leaves and which performs photosynthesis, are an organelle that contain chlorophyll.
Oxygenic photosynthesis and anoxygenic photosynthesis are the two different types of photosynthetic processes. They both adhere to very similar principles, although oxygenic photosynthesis, which is found in plants, algae, and cyanobacteria, is more prevalent.
Light energy is used in oxygenic photosynthesis to convert water (H₂O) absorbed by plant roots in the form of CO₂ and generate carbohydrates. In this process, the water is "oxidised," or loses electrons, while the CO₂ is "reduced," or gains electrons. Carbohydrates are generated along with oxygen.
By absorbing the CO₂ that is created during respiration and delivering oxygen back into the air, oxygenic photosynthesis acts as a counterweight to respiration.

The answer is Nuclear Technology.
In atomic innovation, the nuclear cores of radioactive fuel experience atomic response. Atomic power is the utilization of atomic responses that discharge atomic vitality to create warm, which most much of the time is then utilized in steam turbines to deliver power in an atomic power plant. Atomic power can be acquired from atomic parting, atomic rot and atomic combination. Atomic innovation at that point produces nuclear vitality and discharges it as power.
Currents transport heat and warm the air above.
Ocean biome is a biotic community that is present in the ocean. An ocean biome is the largest biotic community that supports and allows various marine life-forms to thrive and live. An ocean biome supports all sorts of marine life-forms right from fishes to whales, along with other exotic creatures.
