What do you observe about the structure
of the white blood cell? How do you think
this is related to its function of trapping
pathogens in the body?
Please help I’ll give brainlyiest

Answer:

White blood cells engulf and digest pathogens and any other unknown material in the blood and tissues. They engulf the pathogen into a vesicle called a phagosome. This fuses with a lysosome and the enzymes break down the pathogen.

White blood cells foremostly recognize any pathogen or foreign substance in the body and then engulf it with the help of receptors like Toll-like receptors. Finally, the killing of antigen takes place by phagocytosis.

Pathogens may be defined as any microorganisms which are capable of inducing diseases in other living organisms.

After engulfing, the antigen is packed under a vesicle known as a phagosome. This phagosome is then treated with lysosomes to form a structure known as phagolysosomes.

Thes phagolysosomes are responsible for the breakdown of antigen, which is then presented by MHC molecules to perform perforin-granzyme mediated killing of antigen.

Therefore, it is well described above.

Which process BEST explains how DNA is replicated?
A)
DNA is conservative. The original strands of nucleotides do not separate. A
copy composed of two new strands containing all of the new DNA base
pairs is produced to come together.
DNA is semi-conservative. The original strands of nucleotides do not
separate. A copy composed of two new strands containing all of the new
DNA base pairs is produced to come together.
B)
DNA is semi- conservative. The original strands of nucleotides do not separate. A copy composed of two new strands containing all of the new DNA base pairs is produced to come together.
C)
DNA is semi-conservative. The two strands of nucleotides separate. It
produces two copies of the original DNA molecule, each of which contains
one of original strand, and one new strand.
D)
DNA is dispersive. The original DNA chain breaks and recombines in a
random fashion before the double helix structure unwinds and separates to
act as a template for messenger RNA synthesis.

WILL GIVE BRAINLIEST.Read the passage. Seth sat at the piano, and I saw him take a deep breath. Sweat was dripping off of his brow, and his left hand was twitching slightly—the obvious result of nerves. He took another deep breath and slowly, painfully exhaled. Then, he gently placed his hands on the keys and his fingers began to move gracefully up and down the keyboard. What emerged was the most beautiful music I had ever heard. Why is this passage an observation? It tries to reflect the everyday lives of ordinary people. It describes an event the writer has witnessed. It reveals a deep truth about a character. It portrays the physical appearance of a person.
