Answer:
It's false ok it's non electrolyte
Answer:
protists that produce a hard outer covering have left many fossils, other protists lack hard parts, so few fossils of these organisms have been found. ... Protists in this group are called plantlike because, like plants, they contain the pigment chlorophyll in chloroplasts and can make their own food.

Hope it helps, some how.
Answer:
49.3% 81Br and 50.7% 79Br or 
81Br and 
79BR
Step-by-step explanation:
To get the fraction-of-occurrences of the isotopes we must write the following equation. x is the isotopic abundance of 81Br, we can use 1 - x to get the isotopic abundance of 79Br.
(78.918)(1 - x) + (80.916)(x) = 79.903
78.918 - 78.918x + 80.916x = 79.903
1.998x = 0.985
x = 0.493
0.493 × 100 = 49.3% 81Br
100 - 49.3 = 50.7% 79Br
49.3% 81Br and 50.7% 79Br or 81Br and 79BR
Answer:
Presence of 'Eucalyptus' tree species
Explanation:
The koalas are commonly known as the koala beers. They are arboreal animals that belongs to the class of mammal known as the 'Mursupials', and they are herbivorous in nature and found to be dominantly present in the country of Australia.
The factor that allowed the population of koala to grow significantly beyond their habitat could sustain is the presence of 'Eucalyptus' tree species on which they are directly dependent on. This type of tree is commonly found in countries such as Australia and Tasmania, where the climate is suitable and there occurs sufficient amount of rainfall.
