Answer:
many alveoli are present in the lungs with a shape that further increases surface area. Thin walls - alveolar walls are one cell thick providing gases with a short diffusion distance. Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface.
Explanation:
Answer:
ATP is the energy currency of the cell. The synthesis of ATP occurs during cellular respiration in the cell. This energy is used by cells to perform the different metabolic functions of the cell.
The energy is stored in the terminal phosphoanhydride bonds. This bond is called a high energy bond and when this bond is broken down then this high energy is released in the environment and is used to perform the important functions of cells. After the breakage of the bond, ATP converts into ADP.
b. Fetal period
c. Preimplantation period
d. Unattached conceptus?
Answer;
Embryonic period
Explanation;
The germinal stage is the period of gestation from fertilization or conception, when the egg meets the sperm, to implantation of the embryo in the uterus. The embryonic stage of gestation is the period after implantation, during which all of the major organs and structures within the growing mammal are formed.
-Embryonic period begins at fertilization (penetration of the egg by the sperm) and continues until the end of the 10th week of gestation (8th week by embryonic age). The period of two weeks from fertilization is also referred to as the germinal stage.

Answer:
Pigments absorb the light (capture as much light energy as possible) used in the process of photosynthesis.
Explanation:
Photosynthetic pigments are chemical compounds that absorb and reflect certain wavelengths of visible light, that is, they absorb light and have a color.
They are vital components for the process of photosynthesis, the most important pigment is chlorophyll. Chlorophyll is a large molecule, which captures the energy of sunlight and converts it into high-energy electrons. This occurs during the light reactions of photosynthesis, while high-energy electrons are subsequently used during dark reactions in the synthesis of glucose.
B.the mutations that take place in an organism’s DNA
C.the way that most species become extinct
D.the adaptations that help an organism fit into its environment
The water bodies affects the climate of the particular place because it influences the air pressure near the water bodies.
The heated air takes much energy to heat the water bodies so the environment there is moderate.
In case when the air is cooler than water then heat goes from water to air and it does not takes much energy to raise the temperature of the air.
In this way the climate is moderate at the coastal regions.
