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.

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.

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)

1) Identify the most abundant greenhouse gas.
It seems to be Carbon dioxide in your chart
2) State one human activity that is the source of this gas.
Try, The gas that the vehicles spew out while moving (Is it good enough?)
3) State one negative effect of greenhouse gases in the earths atmosphere.
Too much of any greenhouse gases could lead to our planet warming up or Global Warming.

You are employed at a biotech company, working on a new drug, named XYZ. Your boss wants to know how this compound move into red blood cells, and what its concentration will be in red blood cells. He has provided you with plenty of samples of drug XYZ, and you have the means to measure its concentration (mol^-1) inside and outside red blood cells, as well as the concentration of any metabolites of drug XYZ. He has now asked you for a protocol. Provide protocol to test this options:
a. The drug will move into red blood cells by diffusion, but may be metabolized to another compound over time.
b. The drug will move into red blood cells by diffusion and, with time, have equal concentrations in red blood cells and plasma.
c. The drug will enter red blood cells by protein-facilitated diffusion, and, with time, have equal concentrations in red blood cells and plasma.
d. The drug may be actively taken up by the red blood cells by protein-mediated transport.

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).

How does the heart deliver oxygen to the body cells
Answer:
It is the heart pumps oxygenated blood to the rest of your body.
Explanation:
It doesn't affect how oxygen and carbon dioxide exchange (which is done in the lungs), it only pumps the blood through the body. In simplest terms.
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.

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.

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.

Which is a correct statement about mutation?
A: Mutation decrease variety in the population.
B: Mutation increase variety in a population.
C: Mutation ensure alleles never change.
D: Mutation are always bad.
Answer: B: Mutation increase variety in a population.
Explanation:Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.
