    Leptin  hormone  is  secreted   from  fat  cells  and  it  helps  to  regulate  body  weight.  Leptin  hormone   is  predominantly made  by  adipose  cell that    help  to  regulate  energy  balance   by inhibiting  hunger. leptin  hormone  is opposed  by  the  action  of  the  ghrelin  hormone which  is  a  hunger  hormone/

Which of the following is a good predictor of biodiversity in terrestrial ecosystems?
finlep [7]

The correct answer is - predator species in a community.

In the terrestrial ecosystems, a very good and usually sure predictor of the biodiversity is the existence of a predator species. The more predator species there are, the higher the biodiversity, and vice versa, the less predator species, the lesser the biodiversity.

The reason why the predators are such a good predictor of the biodiversity is that they are the species that are on the top of the food chain. That means that the predators are dependent for their survival on all the other species bellow them in the food chain, which is pretty much all species apart from themselves.

If a predator is present, than there has to be pray. If there's pray, omnivores and herbivores, than there has to be plants. All of the organisms are connected to one another, and the ones on the top of the food chain are the most dependent on the others, thus their existence usually means a healthy ecosystem with higher biodiversity.

Which three statements correctly describe the endoplasmic reticulum?
Sunny_sXe [5.5K]

I have searched everywhere, but I have not found the proposals of the question, but I will explain to you what is the endoplasmic reticulum so that you can answer it.

The endoplasmic reticulum is a eukaryotic organelle located in the cytoplasm.

The endoplasmic reticulum is a network of membrane tubules (often interconnected) scattered throughout the cytoplasm of eukaryotic cells. Its membrane, which alone represents more than half of the cellular membrane system, is in contact with the nuclear envelope.

The endoplasmic reticulum can be:

Granular (or rough) (RER) that is to say associated with ribosomes.

Smooth (SER).

The granular endoplasmic reticulum is the place of synthesis (in the associated ribosomes) of the proteins secreted outside the cell and of the proteins and lipids constituting the membranes of the cellular organelles. Golgi, lysosomes, mitochondria, nucleus, ribosomes, vesicles ...). It participates in the correct folding of the proteins that have just been synthesized.

The smooth endoplasmic reticulum participates in cellular metabolism, synthesizing lipids and storing calcium.
