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.

Brrunno [24]

What is a gene?

  • According to Mendel something was being stably passed down, unchanged, from parent to offspring through the gametes, over successive generations. He called these things as ‘factors’ now called as genes. Genes, therefore, are the units of inheritance.
  • They contain the information that is required to express a particular trait in an organism.
  • Genes which code for a pair of contrasting traits are known as alleles, i.e., they are slightly different forms of the same gene.
  • There is no ambiguity that the genes are located on the DNA, it is difficult to literally define a gene in terms of DNA sequence.
  • The DNA sequence coding for tRNA or rRNA molecule also defines a gene. A cistron is defined as a segment of DNA coding for a polypeptide, the structural gene in a transcription unit could be said as monocistronic (mostly in eukaryotes) or polycistronic (mostly in bacteria or prokaryotes).

Answer:

Differences in temperature or precipitation determine the types of plants that grow in a given area (Figure 1). Generally speaking, height, density, and species diversity decreases from warm, wet climates to cool, dry climates. Raunkiaer (1934) classified plant life forms based on traits that varied with climate.
