A statement that would be least likely used too describe variation is
“Variation is something that moves”
That is a least likely description.
Answer:
0.1
Explanation:
To calculate this, scientists use a formula called the biodiversity index in order to describe how much are the species of a given area diverse. It is calculated by taking the number of species in the area and divided by the total number of individuals in that area. This gives us the biodiversity index.
In this example, there are 15 species in an area and we divide that by 150 organisms to get a 0.1 biodiversity index.
The right answer is: Bleeding oesophageal varices
Bleeding oesophageal varices occur when swollen veins (varicose veins) of the lower esophagus rupture and bleed.
Oesophageal varices may leak blood and eventually rupture. This can lead to serious bleeding and life-threatening complications, including death. When that happens, it's a medical emergency.
