Bacteria are prokaryotes and microscopic in size, and they lack a nucleus. DNA is present in the cytoplasm. They do not have membrane-bound organelles.
<h3>What is the size of bacteria?</h3>
- The shapes and sizes of bacteria are extremely diverse.
- The majority of bacteria have a 2–8цm length and a diameter of 0.2-2цm.
- Eukaryotic cells are around ten times larger than bacterial cells.
<h3>What is the difference between prokaryotic and eukaryotic cells?</h3>
- Prokaryotic cells are primitive cells that are primarily present in unicellular organisms; they lack a nucleus but contain a small amount of DNA and do not have membrane-bound organelles.
- In contrast, eukaryotic cells are present in all types of multicellular organisms, including plant and animal cells.
- It possesses a nucleus. All cell organelles are membrane-bound.
- Because they lack a nucleus and other cell organelles and are single-celled microorganisms, they are categorized as prokaryotic organisms.
Bacteria are tiny organisms. They are 200 micrometers in diameter. They do not possess membrane-bound organelles.

The answer is atrial depolarization. The P wave of a normal electrocardiogram specifies atrial depolarization. In addition, depolarization happens in the four compartments of the heart which is both atria first and in both ventricles. The sinoatrial or as called as SA node on the wall of the right atrium starts depolarization in the right and left atria that can cause the contraction in which it is symbolized by the P wave on an electrocardiogram.
Answer:
The correct answer is diffusion of innovation theory.
Explanation:
The DOI or diffusion of innovation theory was postulated in 1962 by E.M. Rogers. It is considered as one of the oldest theories in the field of social science. It was deduced in order to illustrate how with time, a product or an idea attains momentum and spreads via a particular social system or population. The eventual outcome of this diffusion is that the individuals, which are the components of a social system, adopts a novel behavior, notion, or a product.
Here adoption signifies that an individual does something distinctly than what he or she was doing previously. The prime condition of adoption is that the individual must acquire the behavior, idea, or product as a novel or innovative thing. Getting amended with a novel concept, product, or behavior does not take place instantaneously within a social system, however, it is a thing in which some individuals possess the tendency to adopt a new thing more easily in comparison to others.
Answer:a. Draw Punnett squares for each couple (you may need to do more than 1 square/ couple)
Baby 2 MUST belong to the Browns because Mr. Brown is the only parent with an A allele to
contribute… then the rest works out as follows:
b. To which parents does baby #1 belong? Why? Hint you may want to refer to your Punnett
squares.
Baby 1 must belong to the Smiths, because they are the only ones with the possibility of EACH
having a recessive allele to pass down to the baby, Mr. Brown has type AB blood and therefore
only has the dominant A and dominant B alleles – no recessive allele possible.
