What will happen if reading the code in two pairs of nucleotides is not sufficient
Answer:
The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).

3 examples of biotic factors
Answer:
animals, plants, trees, grass, bacteria, moss, or molds.
Explanation:
Biotic components, or biotic factors, can be described as any living component that affects another organism or shapes the ecosystem.
Answer:
In general, biotic factors are the living components of an ecosystem and are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores. Examples of biotic factors include: Grass as producers (autotrophs). Mouse, deer, and owl as consumers
Explanation:
why are only two phenotypes possible?
Answer:
The phenotype is the physical manifestation of an organism's allellic combination (genotype). For the pea plants, if the red allele is dominant and the white allele is recessive, only two phenotypes are possible. ... Often, organisms will carry a dominant and a recessive allele of a gene.

What happens in the first part of Interphase?
Answer:
Interphase is the part of the cell cycle that is not observable by naked eyes. During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). A common misconception is that interphase is the first stage of mitosis, but since mitosis is the division of the nucleus, prophase is actually the first stage. In interphase, the cell gets itself ready for mitosis or meiosis.

Glucose is a molecule that can move across the cell membrane. If the concentration of glucose is higher outside the cell then what will happen by the process of diffusion?
Answer:
The water inside the cell leaves outside

Examples of homozygous recessive?
Answer:
Please mark as brainliest....thanks!!!
Explanation:
An organism can be homozygous dominant if it carries two copies of the same dominant allele, or homozygous recessive if it carries two copies of the same recessive allele. Heterozygous means that an organism has two different alleles of a gene.
A homozygous recessive allele combination contains two recessive alleles and expresses the recessive phenotype. For example, the gene for seed shape in pea plants exists in two forms, one form (or allele) for round seed shape (R) and the other for wrinkled seed shape (r)

Viruses evolve and reproduce. They have genes encoded on nucleic acids.
They are not able to reproduce without a host. They don't have their own cytoplasm.
Prokaryotes have beneficial roles in the carbon and nitrogen cycles. They help to make the carbon in the air usable by plants and break down nitrogen into the reactants that can be used by other organisms.
Viruses recognize specific receptors that are embedded in their host's cell membranes. These receptors are normally used by the cells as gateways, but viruses can insert their DNA or RNA into them. That they must recognize specific receptors limits them to only infecting the species that have that particular receptor. They can infect cells because they're designed in such a way to only infect species and cells. Once inside the cell, the virus can begin reproducing.
Metagenomics has advanced our understanding of how prokaryotic organisms exist and function in natural ecosystems. We are coming to understand that different species assemblages are associated with different health outcomes.

What is the utilized equipment for studying fluorescence-labelled cells? What are the advantages of labelling the cells?
Answer:
Fluorescent labeling of cells helps in ensuring more visibility of the properties of the cell.
The equipment used in studying fluorescence-labelled cells include epi-fluorescence microscope which helps in providing a more dimensional view of the cells. The spectrophotometers is also used to determine the chemical properties of the cells through the intensity of light measured with this equipment. The flow cytometer is also used in this process of study of fluorescent labeled cells.

what describes the relationship between DNA, genes, and chromosomes
Answer:
DNA ( deoxyribonucleic acid) is a chemical substance which is called as the genetic material of all living organisms. It is packaged into the threadlike structure, called as chromosomes. This means that chromosomes are composed of a chemical substance, which is called as DNA.
Whereas, genes are the segment of DNA ( which code for specific proteins) present on the chromosomes. Thus, they carry information for specific trait of the individual ( like eye color)
In summary, their composition and functions are similar as all play a significant role in passing information from one generation to next and thus, determine the characteristics of the offspring.
Answer:
DNA carries instructions for making the proteins a cell needs.
DNA molecules are found in chromosomes.
Genes are segments of DNA that contain instructions that code for proteins.

The Amur plate, a small plate, has moved away from the Eurasian plate. It has moved125,000 meters in 25 million
years. It is moving eastward.
What is the rate of motion of the Amur plate? Express your answer in
year mm
Where would the plate be after 1 million years? Express your answer in m.
What geologic feature will form between the Amur and Eurasian plates?
What is the rate of motion of the Amur plate? Express your answer in .
✔ 5 mm/year
Where would the plate be after 1 million years? Express your answer in m.
✔ 5,000 meters east
What geologic feature will form between the Amur and Eurasian plates?
✔ new ocean floor
The answers are:
Rate of motion is 5 mm/yearThe plate would be 5,000 meters east An ocean floor would form between the Amur and Eurasian plates.The rate of motion is in mm per year so you need to convert the distance it has moved to millimeters.
1 meter = 1,000 meters
125,000 will therefore be:
= 125,000 * 1,000
= 125,000,000 millimeters
Rate of motion = 125,000,000 / 25,000,000 years
= 5 mm/year
The plate is moving east and in 1 million years it would be:
= 1,000,000 * 5 mm/year
= 5,000,000 mm
In meters this is:
= 5,000,000 / 1,000
= 5,000 meters east
Because the Amur and the Eurasian plates are moving apart, the ocean would have to fill up the space left which would lead to the development of a new ocean floor.

The complement pathway is a critical mechanism for eliminating microbes, and is comprised of more than 30 proteins that are constitutively produced. Many of these proteins are synthesized as inactive pro-enzymes, and become active proteases when they are cleaved by an upstream member of the complement cascade. Importantly, the initiation of the complement cascade does not rely on the presence of antimicrobial antibodies, as:___________. 1. any antibody can activate the complement cascade, regardless of whether it has bound the pathogen 2. complement activation will induce antibody production 3. antibody-independent pathways of complement activation rely on complement components that directly bind to microbial surfaces 4. the pathway can still induce inflammation even in the absence of initiating signals to activate the complement cascade
Answer:
3. Antibody-independent pathways of complement activation rely on complement components that directly bind to microbial surfaces.
Explanation:
There are three pathways of complement activation:
The classical pathway.The alternative pathway.The lectin pathway.The classical pathway is triggered by binding of C1 either to the pathogen surface or to antibody bound to the pathogen.
The alternative pathway is triggered by the spontaneous hydrolysis of soluble C3 to C3(H₂O) and initiates eventual deposition of C3 convertase on microbial surfaces.
The lectin pathway is triggered by the binding of mannose-binding lectin or ficolins to carbohydrate residues in microbial cell walls and capsules.
