Answer;
Structure B (chloroplasts)
Explanation;
The process of Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts contain a green pigment called chlorophyll. This pigment is responsible for absorbing light energy or sunlight from the sun that is used to breakdown or split water molecules into hydrogen ions and oxygen atoms, during the light-dependent stage of photosynthesis.
hydrogen bonding is the awnser i believe
Well the soil classification is usually done on the basis of particle sizes and composition of soil.
<span>Clay </span>usually consists of particles less than 0.075 mm in size. It is a sticky soil and shows great changes in volume with variation in its water contact. It also shows considerable strength when air dried.
<span>Silt </span>has larger particles than clay and are mainly inorganic in nature. The particle size is less than 0.075mm and exhibits slightly plastic or non plastic behaviour.
Humus is soil consisting of dead and decaying organic matter. It is mainly organic in content but some inorganic particles may be mixed in it. The top soil in a tropical forest may be considered as humus.
Answer:
I think it is the excretory system
Answer:
Option (2).
Explanation:
Ames test is used to identify the mutageneicity of the compound. The bacteria are treated with chemicals in the nutritive environment to determine whether the substance can acts as a mutagen or not.
The bacteria that can restore the biosyntheic activity in the environment can be considered as mutagen. The mutant bacteria can be easily identified in the Ames test.
Thus, the correct answer is option (2).
