Answer:
The best answer to the question: If every gene has a tissue-specific and signal-dependent transcription pattern, how can such a small number of transcriptional regulatory proteins generate a much larger set of transcriptional patterns? Would be:
Because transcriptional regulators, which are the ones responsible for initiating, and stopping, transcription of RNA into protein, often work in pairs, one goes with the other, and thus increase the regulatory capabilities over gene expression so that the genes translated into RNA and then transcribed into aminoacids in protein chains, actually code for the correct protein types.
These regulators will both stand, as appropriate, on a specific gene to promote its transcription, or prevent it, depending on the different signaling mechanisms received.
Answer:
Pituitary gland, also called hypophysis, ductless gland of the endocrine system that secretes hormones directly into the bloodstream. The term hypophysis (from the Greek for “lying under”)—another name for the pituitary—refers to the gland's position on the underside of the brain.Your pituitary (hypophysis) is a pea-sized endocrine gland at the base of your brain, behind the bridge of your nose and directly below your hypothalamus. It sits in an indent in the sphenoid bone called the sella turcica. The pituitary gland is one of eight interrelated major endocrine glands: Pineal gland.Through secretion of its hormones, the pituitary gland controls metabolism, growth, sexual maturation, reproduction, blood pressure and many other vital physical functions and processes.There are four hormones secreted by the anterior pituitary gland that control the functions of other endocrine glands. These hormones include thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), and luteinizing hormones (LH).
The correct answer to this open question is the following.
Although there are no options attached we can say the following.
This mechanism describes the necessity of males to lead and form their own pride to show their dominance and power. That is why young lions leave and wander, and when they are ready, they fight for their right to lead their own pride.
So yes, Females tend to stay in their pride, but males may leave to join another pride. And that is the male instinct for lions in the wildlife.
On the other hand, males tend to stay in the same pride, taking care of their cubs, raising them, and hunting. That is what they do best, hunt animals to feed the pride and the cubs.
Just like plants on land, ocean-going plankton need light from the sun to prosper and grow. But light is absorbed by ocean water, and some colors of light are absorbed more readily than others.That's why nearly all photosynthesis in the ocean takes place in the sunlit upper layers.
