At all times, all genes are active and code for proteins. true false

The given statement is False.

Gene ( segment of DNA that corresponds to particular protein) expression is a process by which a protein product is produced through transcription and translation of gene.

Gene expression is highly regulated process, which means that genes are only turned on whenever their protein product is required by the body ( for instance, insulin gene is turned on only when blood glucose level is high in the body).

Moreover, particular genes are activated in specific cells and other genes are turned off in order to make cell function in a specific way. Also, there are non protein coding genes in the cells that do not code for any protein.

Thus, given statement is False.

where is the diagram?

if you insert the diagram ill be able to you

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
