Answer:

Nervous system: This systems helps the five sense organs (eyes, ears, nose, tongue, skin) which all contain nerves that send messages to the brain about what is happening. The brain produces a response which it sends via other nerves to the muscles.

Digestive system: This system helps to break down food into simpler substances so it can be used and absorbed into the body. It takes place in the alimentary canal (food tube), mainly in the stomach and small intestine. The digested food is absorbed into the blood.

Respiratory System: This system helps take in oxygen and removing waste carbon dioxide. Air enters the lungs by movement of the rib muscles and diaphragm. The oxygen is absorbed into the blood.

Reproductive system: This helps produce offspring. Eggs are produces by ovaries in a female and the sperm is produced in the testes of a male. They then try and fertilise the eggs.

What dies survivor ship curve mean? What an easy way to remember what it means?
vredina [299]
Survivorship curve = so, first of all, it's a curve, as in a graph.

It describes "survivorship" - the rate of survival, in other words: out of 100 organisms that are born, how many survive. This rate is different among species, for example, most humans live out to most of their life span, and almost all can survive well beyond a reproductive age.

However, in frogs for example, many many individuals are born, but only few can survive to adulthood: most die very young, before reproductive age.

So if you hear about a new species: let's say dogs, and you want to know how long they would live, you would look at their sirvivorship curve (and in some breeds of dogs, those that are likely not to be in shelters, but in homes, the survivorship curve would be similar as in humans: almost all individuals born can live long.

Eva8 [605]

Answer:

BitTorrent protocol

Explanation:

BitTorrent is a system that allows the sharing of almost any file over the internet, being mainly used for the distribution of videos, music and software. It is quite popular because it is an easy tool to use and at the same time very efficient.

BitTorrent itself is actually a data sharing protocol and not a centralized system. There is no server providing the data, but a standard of communication between multiple computers that allows files to be located, distributed and retrieved by all. This protocol is very much used for pirate sharing of music and movies.

Alik [6]

Answer:

The (rough) endoplasmic reticulum

Explanation:

The endoplasmic reticulum is a system of interconnected membranes that functions in the synthesis of several membrane-related proteins and lipids. There are two types of endoplasmic reticulum in the eukaryotic cell;

  • Smooth endoplasmic reticulum
  • Rough endoplasmic reticulum

The smooth endoplasmic reticulum is actually smooth because it has no ribosome attachment while the rough endoplasmic reticulum appears rough due to the attachment by ribosomes.

<em>Therefore, the name of the specific organelle that is studded with ribosomes in eukaryotic cell is endoplasmic reticulum.</em>
