These two apply.
1.) The sporophyte of seed plants is photosynthetically independent.
2.) In seed plants, dispersed spores contain a multicellular gametophyte.
The first option is the correct awnser
Answer:
The correct answer is option b) "the number of chemical bonds between the molecules".
Explanation:
Chemical bonds are the forces that enable the formation of compounds. The number of chemical bonds is a determining factor to know if an interaction will be transient of stable. The more chemical bonds the more stable an interaction will be. Few chemical bonds between molecules makes an interaction unstable and easy to break, enabling transient interactions that are key to certain biological pathways.
Answer:
d. an onblique muscle layer
Explanation:
The alimentary canal has four main layers:
Mucosa (innermost layer which surrounds the lumen), submucosa (connective tissue with blood vessels, lymphatics, and nerves), muscular layer, serosa ( outermost layer of connective tissue).
Muscular layer is subdivided into:
• the inner- arranged in circular rings, prevents food from travelling backward
• outer layer- arranged longitudinally, shortens the tract.
The stomach has an extra layer called inner oblique muscular layer (churning function).
Answer:
What are made in the light reactions of photosynthe
Explanation:During the light reactions of photosynthesis, light from the sun is captured through a series of reactions involving the chemical chlorophyll. This results in the synthesis of two high energy chemical compounds: ATP and NADPH, the latter whose chemical energy is held by electrons that can be transferred easily to other compounds.
