Is the phosphate group attracted to water (hydrophilic) or is it repelled by water (hydrophobic)

1 answer:

6 0

Answer: The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic. Since the heads are hydrophilic, they face outward and are attracted to the intracellular and extracellular fluid.

<span>Scientists who wish to clone genes of interest into bacterial plasmids utilize restriction enzymes, which cuts the target and vector DNA at specific sites. then DNA ligase is used to form covalent bonds between the resulting fragments to complete the recombinant DNA molecule.

</span>

<span>Restriction enzymes (endonucleases) are enzymes which recognize specific target sequences (recognition sites) and will make a double-stranded cut in the DNA molecule at or near recognition sites.</span>

DNA ligase is an enzyme which uses ATP to link two DNA molecules if they have matching ends.

Two football players are running toward each other. One football player has a mass of 105 kg and is running at 8.6 m/s. The othe

IceJOKER [234]

105 kg and velocity = 8.6 m/s
Momentum = 105*8.6 = 903 kgm/s

90 kg and velocity = -9.0 m/s
Momentum = 90*-9 = -810 kgm/s

Momentum of the system = 903 + (-810) = 903 - 810 = 93
Momentum of the system = 93 kgm/s in the direction of the first football player.

Phantasy [73]

Answer:

Considering that the organism is immobile, it produces spores so it reproduces asexually, it is autotrophic, and multicellular, this organism could be a plant. Plants in general do not move, are autotrophic, producing their own food through photosynthesis, are multicellular and can reproduce asexually by sporulation. Thus, this organism could be from the Kingdom Plantae.
