Answer:
The circulatory system of a human compared to that of a frog is different due to the number of chambers. A frog’s heart has three chambers (two atria, and a single ventricle), whereas a human’s has four (two atria, and two ventricles). The atrium of a frog receives deoxygenated blood from the blood vessels that drain the various organs of the body. The left atrium receives oxygenated blood from the lungs and skin.

The car is blue. What does that tell you about the light interacting with it?
A. Because the blue color wave is being reflected, and all other colors are being absorbed.
B. Because the blue color wave is being absorbed, and all the other colors are being reflected.
C. Because the blue color wave is being transmitted, and the others are not.
Answer:
A
Explanation:
because blue is being reflected, all other colors of light are being absorbed by the car.
Answer:
A: Because the blue color wave is being reflected, and all other colors are being absorbed.
Explanation:
Bright colors reflect light. Dark absorb. So white would reflect and black would absorb. Blue is bright, so it would reflect.

Where a disturbance did not completely wipe out all life and nutrients from the environment, secondary succession occurs and homozygous.
Thus, Despite the fact that fire, flooding, and other disturbances can leave a landscape in ruins, drive many animals and plants away, and bring the biological community back to an earlier stage, the habitat is still alive because the soil still contains nutrients and seeds that were sown before the disturbance.
The homozygous genotypes' two alleles are not expressed over one another in incomplete dominance; instead, an intermediate heterozygote is created.
A significant contributing factor to the variety in the traits or properties of an organism is incomplete dominance.
Thus, Where a disturbance did not completely wipe out all life and nutrients from the environment, secondary succession occurs and homozygous.

What kingdom is the Dandelion in?
animal
protist
fungus
plant
Answer:
D. Plant
Explanation:
Dandelion is a plant with yellow flowers. If the flower is a plant then it would be in the plant kingdom. Flowers aren't animals, nor protists. Protists are organisms that are part of the biological kingdom called the protista. These organisms are not plants, animals, bacteria, or fungi. Fungi (Fungus) are like mushrooms and other types of things like that who feed on dead organisms. Flowers don't feed on dead organisms. So that leaves the plant kingdom.

what is photosynthesis ?
the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
Answer:
Photosynthesis is the physical process in which plants make their food with the help of biotic and abiotic components.

Scientists who study biogeochemical cycles often use the term fixation to describe converting an element from gaseous form in the atmosphere to solid form in the biosphere. For example, in the nitrogen cycle, bacteria are said to fix nitrogen by converting N2 gas into nitrates and nitrites in the soil that are later used to make organic macromolecules such as proteins and nucleic acids. There are many processes involved in cycling carbon, but only one is able to fix carbon from its gaseous form in the atmosphere to solid form in the biosphere. Which process performs carbon fixation
Answer:
Photosynthesis
Explanation:
Carbon fixation refers to the process by which elemental carbon in gaseous form in the atmosphere is converted to a solid form in living organisms. It is part of the larger process known as the carbon cycle. The carbon cycle is a very important cycle which involves the different steps by which carbon is exchanged between living organisms and their environment. The carbon cyclemis divided into the biological carbon cycle and the biogeochenpmical carbon cycle. The biological carbon cycle is the rapid exchange of carbon among living things while the biogeochemical cycle refers to the much slower cycle by which carbon is stored and released from carbon reservoirs in the environment.
In nature, carbon fixation occurs in the process of photosynthesis. During photosynthesis, green plant ( autotrophs) in the presence of sunlight as an energy source uses carbon present in air as carbon dioxide together with water vapour to produce organic biomolecules known as simple sugars which are also stored as starch. The products of photosynthesis are then used by heterotrophs, to return carbon in the form of carbon dioxide back to atmosphere.

Help Please!!
1- How could you tell whether a given sequence was DNA or mRNA?
2- Was it easier to decode messages written in DNA or in mRNA sequences?
3- Which cellular enzymes or machines are you imitating when you "transcribe" DNA into mRNA?
4- Which cellular enzymes or machines are you imitating when you "translate" mRNA into a chain of amino acids?
5- What else needs to happen in a eukaryotic cell between the processes of transcription and translation?
6- In step 5, how did different mutations affect the amino acid sequence that was encoded?
7- Explain why some single nucleotide mutations affect an amino acid sequence and some single nucleotide mutations do not.
8- Explain why nucleotide insertions and deletions affect the amino acid sequence so profoundly.
9- Why could your secret message include only 20 of the 26 letters of the alphabet?
10- Did you find that it was difficult to work with only these letters?
Answer:
DNA sequences use the nucleotides A, T, G, and C, while mRNA sequences use the nucleotides A, U, G, and C.
It was easier to decode the messages written in mRNA sequences because these sequences could be translated directly into the amino acid sequence.
The cellular enzyme that carries out transcription is RNA polymerase.
The cellular machine that carries out translation is the ribosome, which is composed of both rRNA and ribosomal proteins.
In a eukaryotic cell, an mRNA transcript often has additional untranslated regions and a poly-A tail. A eukaryotic mRNA transcript would need to be transported from the nucleus to the cytoplasm before it could be translated.
Some amino acids are encoded by several codons. If a single nucleotide mutation still encodes for the same amino acid, the resulting amino acid sequence would not be affected. This happens most often with nucleotides in the third position of a codon.
If a single nucleotide mutation changes the amino acid encoded, the resulting amino acid sequence would be affected. This happens most often with nucleotides in the first and second positions of a codon.
Nucleotide insertions and deletions cause frameshift mutations, which change the reading frame of translation and will encode completely different amino acids from that point forward.
There are only 20 canonical amino acids, so the letters B, J, O, U, X, and Z are not used as one-letter codes.
It was a little difficult to not use the letters B, J, O, U, X, and Z at first, but there are messages to write without these six letters.
Explanation:
What is it called when a living thing copies the appearance of another living thing as a mean of protection?
O mockery
O mimicry
o a behavioral adaptation
o camouflage
Answer:
It is called mimicry when a living thing copies the appearance of another living thing as a means of protection.
Explanation:
Mimicry is used primarily by living things as a means for protection and to decrease the chances of the living thing being killed. For example, a frog that is prey to a toad could have bright colors (bright color frogs are often poisonous) that don't mean anything to the frog and it's species, but to the toad, the frog is poisonous and should not be eaten, so the toad does not eat the frog because it is brightly colored.
Without mimicry, the frog would have been eaten because it wouldn't have had looked like a poisonous frog, or something that the toad would avoid.
