Answer: Erythrocytes also known as Red blood cell compose about 40-45% of blood
Explanation: 40-45% of the blood volume is erythrocytes i.e the red blood cell. It contains heamoglobin a special protein that carries oxygen to the lungs.
If we are talking cellular respiration, most energy would be found being used in either the Krebs Cycle or for ATP.
The glucose harvested and created by plants is used in cellular respiration to create carbon dioxide, though the energy that the glucose offers is then utilized to perform the Krebs Cycle and helps ATP function at it’s top rate.

The right answer is blastocyst.
The blastocystic Stage of embryo development is characterized by the formation in the center of the morula (embryonic cell group) of a cavity isolated from the external environment: the blastocoele.
In embryonic development, this step precedes gastrulation.
Blastocysts are indeed composed of a hundred cells; they have the shape of a hollow sphere at the bottom of which is the mound of the "embryonic bud" from which the embryonic stem cells are derived.
Answer:
During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Explanation:
The energy for photosynthesis comes from light. Light energy is converted to chemical energy by chlorophyll. There are two sets of reactions, light dependent and light independent. The process mostly takes place in the chloroplasts of plant leaf mesophyll cells. Photosynthesis is the process where a plants uses the sun’s energy to turn light into chlorophyll. Plants produce oxygen during this process and utilize carbon dioxide. Photosynthesis is the single most important chemical process on the earth. Almost all plants needs the sun in order to survive Photosynthesis is the most important chemical process on earth – it provides food and energy for all living creatures who eat the plants that rely on this process to produce their food (glucose). · More than half (70%) of the world’s oxygen is produced by phytoplankton photosynthesis in the world’s oceans.
