The earliest of civilizations were based around river valleys. This allowed them to irrigate fresh water to their crops allowing for better farming and therefore, bigger and better civilizations.
<u>Answer:</u>
For example, the dinosaurs' fossils helped the scientists to learn about their habits, habitats, etc.
<u>Explanation:</u>
Scientists greatly depend upon existing biological evidences of extinct organisms in the form of 'fossils' to study the earlier life existed within the biosphere and the geosphere.
Fossil research allows researchers to learn a great deal not only about the organisms' live form and behaviour but also the Earth's geosphere and biosphere at that time. Specially, transitional fossils are more apt to study as they demonstrate the transitional states of a fossil between the ancestral type and the descendants' recent form.
Answer:
m<E = 105°
Explanation:
The ratio of the corresponding side lengths of ∆STU and ∆DEF are equal. That is:
.
According to similarly theorem, if two ∆s are similar, the ratio of their corresponding lengths would be the same. Therefore, ∆STU is similar to ∆DEF.
Since ∆STU ~ ∆DEF, their corresponding angles are congruent. That is:
<S ≅ <D, this means both are 29° each.
<T ≅ <E, this means they are both equal
<U ≅ <F. this means both are 46° each.
Thus:
m<E = 180 - (m<D + m<F) (sum of ∆)
m<E = 180 - (29 + 46) (substitution)
m<E = 180 - 75
m<E = 105°
Aid for agriculture can help increase food production and do improve the quality and quantity of food available
Answer:
1. C China, 2. B China, 3. C western bias against them keeps them out of studies
Explanation:
- China became the world's largest producer and exporter of textiles, the largest producer and importer of cotton, and the largest producer and exporter of furniture and toys not until the development of the 20th century. China is the biggest producer and the consumer of the coal. it also emits more of the carbon dioxide than any other country about 30% in the world.
