Cells of the immune system are able to respondto the presence of invading organisms because
they recognize the
(1) antigens present on the invaders
(2) antibodies present in invading pathogens
(3) DNA pattern in the nuclei of viruses
(4) antibiotics released from microbes

Answers

Answer 1
Answer: 1.  antigens present on the invaders

Through the antigens present to the invaders the Cells of the immune system can easily able to respond and recognize.  During an infection, chemical signals attract phagocytes to places where the pathogen has invaded the body. 
Answer 2

Sensing the position and movement of individual body parts is an example of which sense? (a)-Kinesthetic
(b)-Vestibular
(c)-Auditory
(d)-Umami Olfactory

Answers

Answer:

(a)-Kinesthetic

Explanation:

  • The Vestibular sense is responsible for our sense of spatial orientation or balance.
  • The Auditory sense is responsible for the perception of sounds.
  • The Umami Olfactory sense is responsible for our sense of smell and taste.

So the answer is (a), kinesthesic. It is thanks to the kinesthetic sense that we can go up stairs easily without stopping to see and carefully control the movement of each of our legs.

Explain why hydrogen atom can become either an ion or a part of molecule

Halophiles are a type of (1)_____ and are considered (2) _____lovers.1)eubacteria, archaea, or virus
2)virus, salt, or heat

Answers

Halophiles are atype of archaea and are considered salt lovers. Halophile organisms thrive in extreme environments thus they are also called extremophile organisms. They can be found in places with high salt content.

Halophiles are a type of archaea and Halophiles are considered salt lovers.

  1. Halophiles are a type of archaea.
  2. Halophiles are considered salt lovers.

Halophiles are microorganisms that thrive in environments with high concentrations of salt, such as salt flats, salt mines, and saline soils.

They have adapted to survive and even flourish in these extreme environments, which would be inhospitable to many other organisms. The term "halophile" is derived from the Greek word "halos," meaning salt, and "philia," meaning love or attraction.

These organisms are classified within the domain Archaea, a group of single-celled microorganisms that are distinct from both eubacteria and eukaryotes.

What enzyme connects the new nucleotides together and proofreads them

Answers

The enzyme that connects new nucleotides together during DNA replication is called DNA polymerase.

What is DNA polymerase?

DNA polymerase is responsible for synthesizing a new DNA strand by adding complementary nucleotides to the existing template strand.

It catalyzes the formation of phosphodiester bonds between the nucleotides, thereby linking them together and forming a continuous DNA molecule.

DNA polymerase also has a proofreading function known as 3' to 5' exonuclease activity. As it adds nucleotides to the growing DNA strand, it can detect and correct errors in base pairing.

If it identifies a mismatched nucleotide, it removes it through the exonuclease activity and replaces it with the correct nucleotide, ensuring high fidelity in DNA replication.
