The answer should be
NaI→2Na+I2. :)
<u>Answer:</u> "Chemical fossils"evidence supports the notion that sponges are some of the earliest known multicellular animals.
<u>Explanation:</u>
Sponges are multicellular animals, may belong to Ediacarian period likely to be 80 million years ago or earlier. They catered through a complex system of internal channels, by moving seawater.
Sponges are soft-bodied and very rarely protected as fossils, therefore finding evidence of existence is giant task. The key of their existence came to know from abnormal chemicals which is a steroids of a particular type generated sufficiently by them but virtually never by ordinary organisms.
Analysis of long strata sequence found in Oman and researchers have been able to extract these "chemical fossils" from samples spanning tens of millions of years — before, during and after the Ediacarian period.This gave clear evidence that sponges had to have evolved long before the great variety of multicellular organisms proliferated at the dawn of that time.
The answer would be B) oxygen. In the electron transport chain, oxygen is a reactant. It reacts with 4 electrons and 4 hydrogens to form 2 water molecules. NAD plus is a product of NADH losing an electron. FAD is a product of FADH2 losing an electron.
It is crucial that we protect, conserve, and support the global population of producers. This claim is supported by the evidence that was discovered in the experiment of the water tank. As seen in the experiment, when the fish were increase, the levels of oxygen were decreased. Then, as soon as more plants (producers) were added to the tank, the oxygen levels increased once again. Theses evidences can be applied on a larger scale of the earth. An analogy could be made between the fish and plants in the tank to the animals, humans, and plants all over the world. As the population of animals and humans continue to grow around the world, more and more trees and plants get cut down. As this continues the oxygen levels will decrease, which can be supported by the evidence in the lab.
Answer:
correct option is C. 130 grams
Explanation:
solution
as carbohydrate is a macro nutrient that is found in many foods and beverage
Most of carbohydrate occur in plant base food
some main natural source of carbohydrate are
- vegetable
- fruit
- nuts
- milk
- grain
- seeds
and for adult age of 19 years to 30 years carbohydrate need is 130 grams per day
and adult male age of 19 years to 30 years fiber need is 38 grams per day
and adult female age of 19 years to 30 years fiber need is 25 grams per day
so correct option is C. 130 grams
