Answer:
A.) conversion of chemical energy to heat energy
D.) Photosynthesis creates energy that the plant stores, and cellular respiration utilizes the energy.
D.) The populations of marsh snails and painted turtles will decrease.
Explanation:
When energy is stored in wood, it is being stored as chemical energy. This energy is being stored in the bonds that hold the wood molecules together. Once you begin to burn the wood, these bonds are breaking. As this happens, the chemical energy turns into heat energy (aka. thermal energy) and is released into the atmosphere.
Photosynthesis converts light energy from the sun into chemical energy that can be accessed by the plant later. During cellular respiration, the plant breaks down the molecules which store the energy in the form of chemical energy and accesses the energy.
When you decreases the amount of phytoplankton, the marsh snails have less food to feed on. As a result, more phytoplankton will starve. This results in the decrease of the marsh snail population. Because the marsh snail population decreases, the same will happen to the painted turtles.
A.) conversion of chemical energy to heat energy
D.) Photosynthesis creates energy that the plant stores, and cellular respiration utilizes the energy.
D.) The populations of marsh snails and painted turtles will decrease.
Based on the food chain below, if a bald eagle acquires 50 kg of energy, how much energy did the zooplankton get from the phytoplankton?
phytoplankton zooplankton bivalves sea ducks bald eagle
500 kg
5,000 kg
50,000 kg
500,000 kg
50,000 x 0.10 = 5,000J energy did the zooplankton get from the phytoplankton. thus option B is correct.
What do you mean by food chain?In ecology, the food chain is the flow of substance and energy from one organism to another in the form of food.
A process cycle from producer to consumer to decomposer is referred to as a food chain.
Plants, herbivores, omnivores, and carnivores all exist. Beginning with plants, moving on to herbivorous insect, spiders, a small bird, a snake, a hawk, a fox, and a lion When a person passed away, a hyena would consume their body. When the hyena passed away, the body would disintegrate, becoming food for worms, and then become fertilizer for plants. so according to 10 percent rule, zooplankton get 5000 j of energy from phytoplanktons.
The food chain's cycle will then repeat itself time and time again.

in analyzing the number of different bases in a DNA sample, which result would be consistent with the base-pairing rules?
In analyzing the number of different bases in a DNA sample, the result would be consistent with the base-pairing rules is A+G = C+T.
What is the RNA base pairing rule?Base pairing occurs precisely: a purine base binds to a pyrimidine – adenine (A) on one chain pairs with thymine (T) on the other and guanine (G) pairs with cytosine (C).
In this case, the base pairing rule states that the number of adenine is equal to number of thymine. Similarly, the number of guanine is equal to number of cytosine.

A forest fire burns down most of the trees in a large forest. The animals that live in the trees are forced to move to other areas. What kind of disturbance is this?
A. Cyclical
B. Small
C. Primary
D. Secondary
Answer: D. Secondary
Explanation:
An ecological disturbance is a circumstance caused by an agent that can be of biological or non-biological origin. The agent is capable of bringing negative changes to an ecosystem. Fire is an example of ecological disturbance. In the given situation, the forest burns down the trees are an example of the direct interaction of fire with the trees; therefore, it is a primary disturbance. Nevertheless, this interaction led to the loss of habitat of animals forced to move to other areas as the fire burned the trees. It is called secondary disturbance.

Answer:
Normal Strand: alanine - methionine - histidine
Mutated Strand: glutamine - cysteine - no third amino acid.
Explanation:
Messenger ribonucleic acid (mRNA) is the RNA that is used in cells for protein synthesis. It has a single strand made by the transcription of DNA by RNA polymerase. It contains four nucleotides: Adenine (A), Guanine (G), Cytosine (C), and Uracil (U).
Before transcribing, we need to create the complementary strand of the DNA. We're going to write out the nucleotides of the complementary strand by matching the nucleotides in these pairs: (A & T) and (C & G).
Normal Strand: GCA ATG CAC
Complementary Strand: CGT TAC GTG
Next, we can transcribe this to find our mRNA. We're going to do the same thing to the complementary DNA strand, but with Uracils instead of Thymines. So our pairs are: (A & U) and (C & G)
Complementary DNA Strand: CGT TAC GTG
mRNA Strand: GCA AUG CAC
You'll notice that the mRNA strand is almost exactly like the new mRNA strand, but with Uracil instead of Thymine.
Each set of three nucleotides is known as a codon, which encodes the amino acids that ribosomes make into proteins. To read the codons, you need to have a chart like the one I attached. Start in the middle and work your way to the edge of the circle. Some amino acids have multiple codons. There are also "stop" and "start" codons that signify the beginning and ends of proteins.
mRNA Strand: GCA AUG CAC
Amino Acids: Ala Met His
Our sequence is alanine, methionine, and histidine.
A frameshift mutation occurs when a nucleotide is either added or removed from the DNA. It causes your reading frame to shift and will mess up every codon past where the mutation was. This is different than a point mutation, where a nucleotide is swapped because that will only mess up the one codon that it happened in. Frameshift mutations are usually more detrimental than point mutations because they cause wider spread damage.
Let's repeat what we did earlier on the mutated strand to see what changed.
Mutated Strand: CAA TGC AC
Complementary Strand: GTT ACG TG
---
Complementary DNA Strand: GTT ACG TG
mRNA Strand: CAA UGC AC
---
mRNA Strand: CAA UGC AC
Amino Acids: Glu Cys X
---
Our amino acid sequence is glutamine, cysteine, and no third amino acid.
As you can see, removing the first nucleotide of the strand caused every codon to change. The last codon is now incomplete and won't be read at all. If this happened in a cell, the protein that was created from this mutated strand would be incorrect and may not function completely or at all.

Write a reflection outlining what this tells you about Canada’s population density. What other information does this tell you
Answer:
With the findings of the 2016 Census count on population and dwellings, Statistics Canada gives Canadians a first look at the most recent national statistical snapshot.
The census counts 35,151,728 persons who said they lived in Canada on May 10, 2016, and displays population growth patterns across the country.
The organization will provide the complete spectrum of census data during the following year, as Canadians commemorate 150 years since Confederation, in order to portray a truthful picture of Canadians' lives and communities.
In 1871, the first census following Confederation recorded 3.5 million people in Canada, while the population figure in 2016 was ten times higher. When Canadians celebrated the 100th anniversary of Confederation in 1967, that number had risen to 20.0 million people (1966 Census).
Canadians have been making their way west for many years. The four founding provinces of Ontario, Quebec, New Brunswick, and Nova Scotia housed the majority of Canadians in 1871, whereas Western Canada was lightly populated. Manitoba, Saskatchewan, Alberta, and British Columbia accounted for over a third of the population in 2016.:

What are the main characteristics of enzymes?Enzymes are proteins that catalyze chemical reactions that occur in living things. They speed up the speed of reactions, which contributes to metabolism. Without enzymes, many reactions would be extremely slow. During the reaction, the enzymes do not change their composition and are not consumed either.
In this case, Allosteric enzymes are enzymes that contain a region separate from the substrate to which small regulatory molecules can bind and modify the catalytic activity of these enzymes.
