<span>All cells in our bodies contain the same exact DNA, believe it or not. It's all epigenetic. The different shapes and functions are due to cellular differentiation and gene expression/silencing.

the first cells likely to encounter a pathogen, such as phagocytes, are professional antigen presenting cells (apcs). this means
Zepler [3.9K]

Professional antigen-presenting cells, such as phagocytes, are the first cells to encounter a pathogen (apcs). This means they have the ability to activate cells of the adaptive immune system.

<h3>What is meant by Pathogen?</h3>
  • A pathogen is an organism that infects its host with disease, and the severity of the disease symptoms is referred to as virulence.
  • Pathogens include viruses, bacteria, unicellular and multicellular eukaryotes, and a wide range of other organisms.
  • The bone marrow of an average healthy adult generates 100 billion new neutrophils per day. Because there are so many neutrophils in the body at any given time, they are often the first cells to reach the site of an infection.
  • Long thought to be a component of the innate immune system, complement has recently emerged as an important regulator of the adaptive immune response.

Therefore the correct option is D)  can activate cells of the adaptive immune system.

Characteristics
Oduvanchick [21]

Answer:

One reason that Organism A and Organism C will be placed in different groups will be due  to their MODE OF NUTRITION.

As described in the question, Organism A has an autotrophic mode of nutrition which means that it has the capability to produce its own food. Organism C is a heterotroph which means it cannot produce its own food and hence will have different properties as compared to the organism A.

Many foods, for example, bacon and salt cod, are preserved with high concentrations of salt applied to the outside of the meat.
Rama09 [41]

High concentrations of salt can inhibit the growth of bacteria by causing the bacteria to shrink because water leaves the bacterial cell.

<h3>What is a Hypertonic solution?</h3>

This is defined as a type of solution which has a large amount of particles which are dissolved thereby making it have a high concentration.

High concentrations of salt applied to the outside of the meat means it is hypertonic and therefore causes the bacteria to shrink because water molecule leaves the cells thereby destroying their structure preventing metabolic reactions from occurring which leads to their death.
