The answer is a because I think so
Both dna and rna have four nitrogenous bases each three of which they share (cytosine adenine and guanine )
Tiny regions at the surfaces of neurons and different cells which are touchy to neurotransmitters or hormones are called receptors.
The required details for receptors in given paragraph
Cellular receptors are proteins both internal a mobileular or on its floor which acquire a sign. In everyday physiology, that is a chemical sign in which a protein-ligand binds a protein receptor. The ligand is a chemical messenger launched with the aid of using one mobileular to sign both itself or a exceptional mobileular. Receptors are proteins that bind to outside messengers to create a chain of downstream consequences that mediate a selected reaction withinside the mobileular. Receptors have a ligand-binding area that acknowledges the particular ligand and the effector area that undergoes conformational modifications to provide a downstream event.
Receptors are available in many types, however they may be divided into categories: intracellular receptors, which can be determined internal of the mobileular (within side the cytoplasm or nucleus), and mobileular floor receptors, which can be determined within side the plasma membrane.

#SPJ4
Water is a polar molecule and the -OH bonds binds to the polar ionic substances and dissolves in it.
Answer: Options are not given.
Here are the options.
A. Autotrophs
B. Saprophytic
C. Parasitic.
D. Both a and b.
E. All of the above.
The correct option is all of the above.
Explanation:
Angiosperms are flowers and seed producing plants and their seeds are enclosed in ovary.The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and then develops
into a or become a seed in an enclosed hollow ovary. They are most diverse and largest group of animal kingdom.
Some angiosperms are autotrophs that uses carbondioxide, water and sunlight energy to produce their own food and releases oxygen.
Examples include maize, rice..
Some angiosperms are saprophytic which obtain energy from dead and decaying matter in the soil. They form a symbiotic relationship with fungi. Example is Neottia.
Some angiosperms are parasitic and they attach to their host through haustoria their by feeding on the host and causing harm on the host.
