Ghrelin is a hunger-stimulating hormone which is secreted by specialized cells in the stomach.
Ghrelin is a hormone made in the intestine. It is often called the "hunger hormone" and is sometimes called lenomorelin.
It reaches the brain through the bloodstream and tells the brain to feel hungry and start looking for food.
It's main function is to increase appetite. Eat more food, take in more calories and store fat.
In addition, it affects the sleep-wake cycle, reward-seeking behavior, taste sensation, and carbohydrate metabolism.
This hormone is made in the stomach and is secreted when the stomach is empty. It enters the bloodstream and affects a part of the brain called the hypothalamus, helping regulate hormones and appetite. Lower levels make you feel fuller and easier to cut calories.

Heterotrophic. Only plants have cell walls, so that goes to phytoplankton, andwhales have thousands of cells, so unicellular goes to plankton again. Mammals aren't prokaryotic, so we're left with heterotrophic.
Answer:
The main purpose of light dependent reactions of photosynthesis is to generate ATP and NADPH.
Explanation:
Photosynthesis consist of two reactions 1 light reaction 2 dark reaction .The light reaction occur in the thylaKoid of Grana to produce Adenosine tri phosphate (ATP) and NADPH
Role of ATP
ATP is an energy rich molecule which undergo hydrolysis to provide energy for Carbon di oxide fixation during dark reaction. The carbon di oxide fixation is very much important to produce glucose.
Role of NADPH
NADPH act as reducing equivalent that carry out the reduction of phosphoglyceric acid formed in the first step of light independent reaction to generate phosphoglyceraldehyde(PGALD). Some PGALD then undergo various enzymatic reaction to form glucose and rest are utilized to regenerate ribulose bis phosphate(RUBP).
During anaphase, homologous chromosomes separate and head towards opposite poles of the cell.
- A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase.
- After the metaphase procedure, the mitotic stage known as anaphase occurs during which the freshly replicated chromosomes are transferred to the opposing poles of the cell and the replicated chromosomes are split.
- Sister chromatids split from one another and are drawn to the opposite ends of the cell during anaphase.
- The sister chromatids are able to separate because the protein "glue" holding them together is degraded.
- Each chromosome now exists on its own. Each pair's chromosomes are drawn to the cell's opposite ends.
