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.

<h2>Answer:</h2>
The correct answer is option A which is an abnormal male with nondisjunction.
<h3>Explanation:</h3>
The karytope is the complete picture of chromosomes present in a cell of an individual.
It is used to study the chromosome number and abnormalities related with chromosome numbers.
Chromosomal nondisjunction is the consequence when the homologous chromosomes are not completely separated from each other during meiosis.
While chromosomal translocation is the crossing over of genetic material between two chromosomes.
Only chromosomal disjunction can be seen from the karyotype.

Answer:
Binomial Naming System
Explanation:
Scientists use a two-name system called a Binomial Naming System. Scientists name animals and plants using the system that describes the genus and species of the organism. The first word is the genus and the second is the species. The first word is capitalized and the second is not.
