A pet dog is a heterotroph because it must obtain nutrients from eating sources of food and cannot create glucose using energy from the sun. It is an omnivore because it eats both plants and meat; Dog food is usually a combination of grains and meat mixed together.

Pet dogs should be classified as omnivores because, since they are tamed, their body will need nutrients from both meat and plants.

Answer: Phagocyte receptors that detect PAMPs

Explanation:

TLRs or Toll-like receptors, are a family of proteins that are part of the innate immune system. TLRs are transmembranous and recognize pathogen-associated molecular patterns (PAMPs), which are groups of chemical characteristics common to certain types of pathogens. Patterns detected by TLRs include lipopolysaccharide, a compound found on the surfaces of Gram-negative bacteria, and double-stranded RNA, which is an integral part of the life cycles of many viruses. These PAMPs are generally important for the survival of the pathogen, so they are well preserved. <u>Activation of these receptors induces inflammatory responses in leukocytes of myeloid lineage, signaling via NF-κB, which is a transcription factor that activates pro-inflammatory genes</u>. Activated TLRs also increase the production of co-stimulatory molecules such as CD80, CD86 and CD40. These proteins, expressed on the surface of antigen-presenting cells, are necessary for the activation of T-lymphocytes by dentritic cells and macrophages already showing antigens in their MHC type II molecules (Major Histocompatibility Complex, they participate in the presentation of antigens to T lymphocytes)

<u>In addition, TLR-mediated signaling on antigen-presenting cells (APCs) plays an important role in linking the innate and adaptive immune responses</u>.

olga_2 [115]

Answer: Point mutation

There are several different types of mutations possible in the base sequence of DNA. If a GGC (glycine) codon were changed to UGC (cysteine), it would be termed a point mutation.

Explanation:

Point mutation is caused when a nitrogenous base (purine or pyrimidine) is substituted by another base of the same or different class in a nucleotide. So, GGC (glycine) codon to UGC (cysteine) signifies the change of the first base - guanine to uracil.

Other types of mutation include insertion and deletion.

But in this case, point mutation is said to have occurred.
