Answer:
Explanation:
Sí, porque Australia es una isla separada en Oceanía, la mayor parte de Australia se encuentra en los trópicos. Australia es la parte más caliente de la tierra en el hemisferio sur, que tiene un clima desértico semidesértico. Al Norte, este, sur-este y sur-oeste semidesérticos pasan a sabanas
.dan paso a bosques de eucaliptos, palmeras. helechos arborescentes a lo largo de las orillas y en las montañas. La fauna australiana se adapta mejor a este tipo de animal.
Allí viven varios animales marsupiales (Canguro, ardilla trepadora, rata trepadora (Koala o oso australiano), ornitorrinco y animales salvajes)
Answer: 4282.928 = 4283 years
Explanation:
Data given;
Carbon 14 half life = 5740
No (initial radiation) = 0.230 Bq/g
Nf (final radiation) = 0.137 Bq/g
First we find the decimal fraction of the remaining half life of the carbon 14
k = No / Nf
k = (0.137 / 0.230) = 0.595652
So to find how many half-life has elapsed, we say
(1/2)^n = k
(1/2) ^n = 0.595652
Therefore
n log 0.5 = log 0.595652
n = ( log 0.595652) / ( log 0.5)
n = 0.747457
To get the elapsed time or how old the sample is;
We say
Carbon 14 half-life × n
5730 yrs × 0.747457
= 4282.928
= 4283 years.
So the sample of the wood is 4283 years old.
Answer: Option B.
Obese and over eating
Explanation:
A leptin deficient move would be obese and overeating because leptin is an hormone produced by fat cells that decrease appetite and when it is deficient in the body,the body assumes that there is no enough fat in the body and it send signals for intense hunger and overeating or uncontrollable eating of food which result in accumulation of fats, there by resulting in obesity.
Carbohydrates
Explanation:
Judging by the content of her note, we can satisfactorily say that Nadia is taking notes on carbohydrates.
Carbohydrates are bifunctional families of organic compounds.
- Carbohydrates are naturally occurring organic compounds containing carbon, hydrogen and oxygen. The ratio of hydrogen to oxygen is 2:1.
- They are usually taken in as energy sources for the body.
- When reduced to simple sugars like glucose, they release their chemical energy.
- They are the main source of energy for the body.
There are two types of carbohydrates;
- Simple carbohydrates are made up of simple sugars like glucose.
- Complex carbohydrates are cellulose and glucose.
