Answer:
Priestly observed that adding a plant to the jar caused the candle to stay lit longer.
Priestly himself inferred that plants gave off oxygen during photosynthesis, it provided the oxygen that was needed for the candle to be able to burn.
Answer:
Joseph Priestly observed that a candle alone in a jar did not stay lit for long and eventually went out and that when he added a plant to the jar, it caused the candle to stay lit longer and the plant to stay alive longer. Priestly then inferred that plants give off oxygen during photosynthesis, providing the oxygen needed for the candle to burn and that the burning candle gave off carbon dioxide, which was used by the plant.
Explanation:
im right! trust me :)
Answer:
A
Explanation:
i just took the quiz on edg.
two seed leaves
netted leaf structure
parallel leaf structure
cotyledons
endosperm
The options for these are Monocot food, Dicot food, Monocots, and Dicots
Mono cots and dicots both have differences which are
Mono cots have one seed leaf while dicots have two seed leaves
Monocots have parallel leaf structure while dicots have netted leaf structure
Monocots store their food in the endosperm while on the other hand the dicots store their food in the cotyledons.
one seed leaf: monocot
two seed leaves: dicot
netted leaf structure: dicot
parallel leaf structure: monocot
cotyledons: dicot food
endosperm: monocot food
Carbon bonding is primarily covalent. Carbon shares electrons with other atoms to fill its valence shell. For example, in a carbon dioxide molecule, carbon forms double bonds with two oxygen atoms.
The question asks about the nature of carbonbonding. Carbon bonding is almost entirely covalent. This means that carbon forms bonds by sharing electrons with other atoms in order to fill its valence shell, or outermost energy level. For example, in a molecule of carbon dioxide, carbon forms double bonds with two oxygen atoms, sharing two pairs of electrons with each.

Question options:
A new scientific law would be established and proven by the findings. A new scientific theory would be established and proven by the findings. A current scientific law would be revised based on the new findings. A current scientific theory would be revised based on the new findings.
Answer:
A current scientific theory would be revised based on the new findings.
Explanation:
If new findings came about and challenged the current theory of natural selection so that Darwin's theory didn't look like it was true at all, the initial theory(darwin's theory of natural selection) would not be entirely discarded but revised according to these new findings and then form a sort of backbone to this new theory which would be based on findings of many independent researchers and not just one. Example: how some of Sigmund Freud's theories or Aristotle's may not be entirely valid today but still works as a fundamental for understanding other theories.
