Answer: 18
Explanation:
This molecule, called ammonia, is a group of atoms held together by chemical bonds. In this example, the atoms (smallest pieces of matter) are nitrogen (N) and hydrgoen (H)
The number 6 indicates the number of moles of the NH3 molecule. A mole is the unit of measurement used to measure the number of atoms or molecules. One mole is equal to 6.02214078×10^23 of the same things.
And since there are 3 Hydrogen atoms found in each mole of ammonia, and there are 6 moles of amminia, then 6 x 3 = 18 atoms of hydrogen.
No 6 is common for N and H. 3 is only for H(Hydrogen).
For finding the number of hydrogen atoms we should multiply 6 with 3
So, 6*3 = 18. So there will be 18 hydrogen atoms in 6NH₃
inflation
steady state
oscillating
inflation theory is correct i know this because the exact definition of the inflation theory is: theory that upholds the big bang theory, but suggests there was an extremely rapid expansion milliseconds after the big bang
b. more carbon in tress in temperate forests
c. rates of photosysnthesis are higher in temperate forests
Answer:
Option A, there is more carbon in the ground in temparate forests
Explanation:
In temperate forests the nutrients are mostly found in the soil including the carbon, while in case of tropical forests these nutrients (including carbon) are up taken by the trees and stored there itself. Now when the tropical forest trees are cut down the carbon reserves with in the trees is destroyed and released in the atmosphere. As per estimate the amount of carbon released by deforestation of tropical forest is much more disastrous than the gas emission of automobiles and industries in the current time.
Hence, option A is the correct choice of answer
b. essential elements.
c. nonrenewable resources.
d. non-recyclable matter.
Agreed. 100% C. Nonrenewable Resources
c. a nucleus.
b. a cell membrane.
d. genetic material.
Answer:
Euglena have diversed nutritional requirements. They are autotrophic when kept in light and heterotrophic when deprived of light.
The Euglena contains chloroplast in it to perform photosynthesis in the presence of light.
When the Euglena is kept in the dark it starts deriving energy from the organic matter around it and shows heterotrophic mode of nutrition.
When light will be provided to Euglena it will start resynthesizes its photosynthetic pigment and it will start perform photosynthesis.
Re-exposure of Euglena to light after chloroplast destruction will not restore photosynthesis; instead, Euglena will continue to survive as a heterotroph until it possibly re-acquires chloroplasts through secondary endosymbiosis or other means.
When Euglena, a microbial eukaryote, is deprived of light and its chloroplasts are destroyed, reintroducing it to light will not prompt the immediate restoration of photosynthesis. Having lost their chloroplasts, they cannot simply regrow them upon exposure to light. Instead, Euglena will rely on its ability to behave as a heterotroph, acquiring nutrients and energy by ingesting or absorbing organic matter from its environment. Euglena is known as a mixotroph, which means it can switch between autotrophic (photosynthesizing) and heterotrophic lifestyles, depending on the available resources. Euglena stores energy in a glucose polymer different from typical starch, and this storage, along with other nutrients absorbed from the environment, can support them when photosynthetic capability is compromised.
