Answer:

D. the Calvin-Benson-Bassham pathway

Explanation:

The Calvin-Benson-Bassham pathway commonly called the C3 pathway is the sequential step of reactions taking place in the stroma of the chloroplast. The Calvin cycle was studied by the radioactive studies in the green alga by Melvin Calvin.

The Calvin cycle takes place in almost every photosynthetic organism from green algae to green plants. The Calvin cycle is important for the plants as it forms the glucose molecules by the fixation of the carbon from the atmosphere and thus is also known as the Carbon fixation cycle in plants.

Thus, Option-D is correct.

AleksandrR [38]
<h2>The answer is </h2>

False

<h2>Explanation:</h2>

According to Sigmund Freud human consciousness have been divided into three levels of awareness: the conscious, precociousness, and unconscious. These stages are never understood by any person at the same time. There is always a transition period between these segments. For example the transition stage from wake to sleep where we see a gradual reduction in consciousness with fuzzy, halfway states in between conscious and unconscious.

Select the three statements that are true. To review the germ layers and the terminology associated with body cavities, see the
soldier1979 [14.2K]

Answer:

A diploblast has no mesoderm.  

A pseudocoelom has the same functions as a true coelom.  In a coelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the tissue lining the outer side of the body cavity.

Explanation:

Diploblast organisms are the ones that have only two primary germ layers. These organisms have outer ectoderm and inner endoderm but no mesoderm. Example: Cnidarians

A true coelom is derived from mesoderm and is completely lined with tissue derived from mesoderm. The outer and inner linings of the coelom are made of muscle layers that are developed from the mesoderm.  

A pseudocoelom is the one that is incompletely lined with mesoderm. Both pseudocoelom and a true coelom serve as shock absorber and provide space wherein the internal organs can be placed. The fluid present in them sere as medium for transport of nutrients, gases, etc.
