Answer:
True,Every chemical reaction obeys the law of conservation of mass.
earth science: fossils question pls help
Answer:
Layers A and B show cratures that would most likely be found in the ocean (they have fins, etc.) then the next layer has no animals and after that the animals beofre are no longer seen. This must mean that the creatures went exticnt due to an envoirmental issues, in this case its a volcanic explosion (as seen in the key in the corner were the shaded area is indicated as volacanic ash). In layer D, we see a plant, this shows us that the envoirment is now land. After that is another layer of volcanic ash and then F. were we see the previous plants and animlas with the inclusion of 'bird'. I think this means that the envoirment has more greenier wether from the nutrients rich soil (due to the volcanic ash) or another factor.

Answer:
A. Nature exists as a resource that should be preserved for future generations.
Explanation:
Deep ecology movement is an idea that all living organisms on the earth have right to live with their basic moral values. All organisms must be respected irrespective of their size, shape or other physical features. Natural resources are scarce and so they should not be wasted and must be saved for future generations.

Describe Darwin's theory of evolution.
I need answers only in points for my lil sis, otherwise i'll report it..I'll reward brainliest to correct answer.
Answer:
Darwin's theory of evolution state that"all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce".
Answer:
Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. Individuals that are poorly adapted to their environment are less likely to survive and reproduce.Which of the following is NOT a source of genetic variation in a population ?
A. Recombination
B. Gene Flow
C. Extinction
D. Mutaion
Part D A scientist comes up with an idea to reintroduce a shark that eats lionfish into the Atlantic Ocean. What are the possible benefits and risks of this idea? In your answer, state two questions you’d ask the scientist before agreeing to the plan.
Answer:
The shark may balance out the lionfish population. However, its presence in the ocean may also negatively affect other organisms. The shark may start preying on natural species, leaving little food for native predators. Two questions to ask the scientist are, Does this shark have any natural predators in the Atlantic Ocean to help control its population numbers? and What other organisms does the shark eat?
Explanation:
i got this from edmentum-
Although some species of grouper and shark may be able to eat them, lionfish have relatively few predators in the area they have invaded because of their deadly spines. Although lionfish are widely distributed, most sharks won't readily eat them.
What eats lionfish into the Atlantic Ocean?The shark might maintain lionfish populations in balance. Its presence in the ocean, however, might also have a harmful impact on other organisms. It's possible that the shark will start eating native animals, leaving little food for them.
Do this shark's natural predators in the Atlantic Ocean aid to regulate its population numbers? Are two queries to put to the expert. What other kinds of creatures does the shark consume?
Therefore, Because the Moray was discovered in a location where divers would not have been searching, this is the first confirmed instance of natural predation of the invasive lionfish in the Atlantic Ocean.

which of the following is an indicator of good water quality?
high levels of nitrates
high levels of phosphates
zero turbidity
all of the above
Answer:
all of above
Explanation:
all of the above
Answer:
Zero Turbidity
Explanation:
High phostphate levels cause excessive algea growth and a decreased level of dissolved oxygen. High levels of nitrates are caused by animal or human waste and the overuse of chemical fertilizers. Low turbidity causes the water to be more clear so zero turbidity is the only right answer. I got it right on my test too
What are the necessary conditions for autotrophic nutrition and what are its byproduct ?
➜ The conditions necessary for autotrophic nutrition are sunlight, chlorophyll, carbon dioxide (CO2) and water (H2O).
The byproducts of autotrophic nutrition are water and oxygen.
Answer:
Carbon dioxide, water, chlorophyll pigment, and sunlight are the necessary conditions required for autotrophic nutrition. Carbohydrates (food) and O2 are the by-products of photosynthesis.
PLEASE HELP!!! I WILL GIVE BRAINLIESTA dichotomous key is a helpful identification and classification tool. Scientist also use genetics (DNA) to classify organisms? Now that we know a little more about dichotomous keys, which is a more accurate way to classify organisms? Explain.
Answer:
DNA contains specific physical characteristics unique to the person to which the DNA belongs. This information helps classify organisms, by type. All sorts of traits are used to classify organisms, but DNA is the best way.

A) two dominant factors
B) one dominant and one recessive factor
C) two recessive factors
D) one dominant gene
Answer:
C two recessive since it gives a high chance of a recessive trait
Explanation:
Answer: C. Two recessive factors
Explanation: Good luck! :D
Let's use red hair for example - r
And we'll say that brown hair is dominant - R
You won't get red hair from RxR, the gene isn't in the punnet square. (Not A.)
Rxr would be always be Brown hair and they carry the red hair gene. (Not B.)
The dominant gene is the opposite of the recessive trait. (Not C.)
