The correct answer is d: a
target cell's response is determined by the components of its signal transduction pathways.
The response of a cell to a hormone depends on the cell’s receptor and a signal transduction. When a peptide hormone binds to a receptor on the cell membrane, a second messenger is activated in the cytoplasm. The second messenger has a role of triggering signal transduction leading to the cellular response. Lots of different signal transduction processes (for example, different intracellular proteins) are used to coordinate the behaviour of target cells.

Answer:
B. Base pairing occurs within an RNA molecule to give RNA the three-dimensional shape needed for specific functions.
Explanation:
Ribonucleic acid, known as RNA, is a type of nucleic acid found in living systems. In opposition to the other type of nucleic acid (DNA), RNA is a short single stranded molecule. Both DNA and RNA are made of nucleotides, composed of a phosphate group, nitrogenous bases and a pentose sugar.
The presence of ribose sugar and Uracil base in RNA instead of deoxyribose sugar and thymine base respectively structurally differentiates the molecule from DNA. However, base pairing occurs within the RNA molecule to form the three-dimensional shape of the RNA, which is key to the specificity of its function.
Answer:
The answer is C (UAAGCUCGU)
Explanation:
T is replaced by U in RNA and A and U "bind". In this case, we're looking for the complementary RNA strand, so all terms are opposite; G becomes C, A becomes U, etc.
Answer:
Neuroscientists conducted research with taxicab drivers in London and found that taxicab drivers, who are required to have a tremendous amount of spatial and geographic knowledge, had a larger <u>hippocampus</u> than other drivers.
Option D.hippocampus
Explanation:
Hippocampus is concerned with following important functions:
- Storage of new information in the memory (converting short memories into long memories)
- Comparing sensory information with what the brain expects about the world
- Enabling us to form spatial memories for investigating the environment
As the geographic knowledge and spatial knowledge is being stored in the hippocampus, the taxi driver surely have greater hippocampus than other drivers.

It has a wider diameter than the small intestine.
