A researcher found that the wild species of almond trees contains a chemical called amygdalin.
This chemical is converted into cyanide inside the human body and can be lethal. The researcher
found that a single gene mutation in some of the wild almond trees resulted in a variety that no
longer produced the chemical amygdalin. This variety of almond is largely harvested for human
consumption. Based on the study, the researcher claimed that some mutations are beneficial in
nature. Was the claim made by the researcher correct? Why or why not?
a) Yes. The mutated variety of almond was edible.
b) No. Not all almond trees produced seeds that were edible.
c) No. The mutation did not affect all varieties of almond trees.
d) Yes. Almond trees with amygdalin grew only in forests.
Answer:
a) Yes. The mutated variety of almond was edible.
Explanation:
Yes, the claim made by the researcher is considered correct because the mutation removes the amygdalin chemical from the almond so these almonds are now safe for eating. This removal only occur through mutation. Mutation is the sudden change occur in the DNA of cell that leads to different functions occur in the body so we can say that some mutation that is occur in organisms are beneficial.

how much energy moves up from one trophic level to the next in the energy pyramid
Answer: Only about 10% of energy is transferred from one trophic level to the next. Most of the rest of the energy is lost through heat (energy expended, metabolic process, respiration) as it transfers along each level. The reason for this energy loss is found in the second law of thermodynamics which states: that as energy is transferred energy is lost.

Reactant
Product
Activation energy
Bond
Endothermic
Exothermic
Rate
A chemical reaction is a process where two or more reactants are converted to one or more products at a given rate, which requires a minimum amount of energy.
A reactant is a starting substance in a chemical reaction, whereas products are formed at the end of the reaction.The rate of reaction is the velocity of the chemical reaction.Activation energy refers to the minimum amount of energy required to activate reactants and thus start a chemical reaction. The chemical reactions store/release energy by destroying/building chemical bonds between atoms/molecules.Exothermic reactions release energy when the bonds are formed; whereas endothermic reactions consume energy.In conclusion, a chemical reaction is a process where two or more reactants are converted to one or more products at a given rate, which requires energy. These reactions can be exothermic processes or endothermic processes.

Please help and thank you.
Answer:
D / D / D / B / C
Explanation:
I just took the quick check myself, got all of them right :)
1 ) Top predators do not increase the number of prey, neither do they create imbalance or increase the food for other predator species. This is common knowledge, so ruling those out you are left with D. As they do in fact maintain the rest of the food chains populations.
2) A top predator in the ocean is a shark. Of course some might mistake a small whale to be a top predator, but sharks are actually known to hunt whales- the small ones anyway. A sea lion fish or a bird wouldn't exactly be a candidate for the top of the food chain either.
3) During seasonal flooding, to an area such as a river, water gets added to the existing pool, and many biotics and abiotics take this to their advantage. As a result- biodiversity actually increases during these times, but once season flooding is over it goes back to being the same.
4) The impact difference of seasonal flooding from damming a river is actually quite big. Seasonal flooding is.. well.. seasonal.. while damming for the most part is permanent, or will be there for much longer time span than season flooding is. Seasonal flooding increases biodiversity, but damming does not. This is becuase of the long term increase of water, the environment has to readapt, as plants that were once there drowned, and the known species most likely ran off to find better environment. Here it takes a while but eventually new abiotic and biotic species adapt and reclaim the dammed area of the environment.
5) Yes, a long term increase in the average temperature would disturb the ecosystem. Even if it's for a little bit, it's still something the environment wouldn't be used to, meaning the plants and animals there would have to learn to adapt for the time being- even if its temporary.
1: It maintains other populations
2: A shark
3: The biodiversity of the area increases
4: Seasonal flooding does not impact biodiversity for as long term as damming.
5: Yes, because such a change could have a large-scale impact on wildlife.

Global warming. In the 1900's when cars were on the up-rise, the CO2 in the atmosphere only consisted of about 0.28%, and summers were only about 65 degrees. Now, in direct coloration with the rising CO2 levels, summers are averaged 78 degrees, reaching highs into the 100's.

Distinguish between an antibiotic and a pathogen.
An antibiotic is designed to kill bad cells to help aid illnesses. However, a pathogen is like a virus or a bacteria that can give a disease. Doctors observe pathogens on a atomic and cellular level to alienate the pathogens weaknesses and what does or doesn't kill it. An antibiotic is commonly used to kill these pathogens and prevent infections.
Basically, the big difference between an antibiotic and a pathogen, is that an antibiotic is used as a source of protection and a pathogen is a seperate living virus (disease). Both are key components of finding cures for harmful viruses and illnesses.

Explain how the structure (order) of DNA can determine the structure of a protein. Use as many of the following terms as you can in your explanation: DNA, base pairs, mRNA, tRNA, ribosome, amino acid, protein, codon, anticodon
The stages of DNA bases in a molecule can determine the order of amino acids in protein molecules. Groups of three bases called triplets represent different amino acids. This is the basis of the genetic code . A sequence of bases (genetic information) on DNA that codes for a protein is called a gene
Protein synthesis is the generation of proteins by cells that employ DNA, RNA, and different enzymes.
What is protein synthesis?It generally includes transcription, translation, and post-translational events, such as protein folding, modifications, and proteolysis the process of protein synthesis.
the mRNA contains the sequence of nucleotides transcribed from the DNA that defines the sequence of amino acids that a synthesized protein will have.
In mRNA, codons are triplets of nitrogenous nucleotides that code for amino acids and using ribosomes mark the beginning and end of protein synthesis.
Therefore, in contrast to mRNA codons, anticodons are triplets of nucleotides found in transfer RNA (tRNA). The linking of amino acids to the polypeptide chain being produced is carried out by tRNA.

Answer:
A temporary lake create salt flats in Death Valley when Holocene lakes began to evaporate.
Explanation:
"Each time it has rained since, a new layer has been added. The flat is a vast area covered in salt that was deposited from evaporated water. When the water runs down the mountain, it dissolves minerals that precipitate out as the water evaporates."

The correct pairing of DNA bases is C with G, and A with T. Therefore option D is correct.
DNA (deoxyribonucleic acid) is composed of nucleotides, which are made up of a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base. The four nitrogenous bases found in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
In DNA, the bases always pair up in a specific way known as complementary base pairing. The bases adenine (A) and thymine (T) form a pair, and cytosine (C) and guanine (G) form a pair.
This pairing is based on the specific hydrogen bonding interactions between the bases:
Adenine (A) always pairs with thymine (T) through two hydrogen bonds.
Cytosine (C) always pairs with guanine (G) through three hydrogen bonds.
This specific pairing of bases is crucial for DNA replication and the accurate transmission of genetic information during cell division and protein synthesis.
The pairing of DNA bases: (D) C with G, and A with T. This pairing reflects the complementary base pairing rules observed in DNA.
