<h2>The correct answer is: Transcription.</h2>

Explanation:

  • Viruses do not possess any machinery necessary for the purpose of their reproduction.
  • They only possess their genetic material enclosed within a capsid structure.
  • The capsid is constituted of glycoproteins.
  • They completely depend upon the components and organelles of the host cells whom they infect to help them carry out their reproduction process.
  • After infecting a host cell, the viruses hijack all the machinery and components of the host cell and use them for the purpose of transcribing their genetic material (DNA or deoxyribonucleic acid) to produce the virus-specific mRNAs (messenger Ribonucleic Acid).
  • These mRNAs are further translated into virus-specific proteins using the host-specific Ribosomes. These virus-specific proteins are required for replicating the viral genetic material and producing the capsid structure.
  • The virus-specific proteins and glycoproteins are synthesized by utilizing the raw materials from the host cells.
  • Transcription is the process by which an enzyme called RNA polymerase or DNA dependent RNA polymerase copies the protein coding region of the DNA (gene) in the form of an RNA sequence (mRNA).
  • The synthesis of the mRNA happens in the 5' to 3' direction. This mRNA is further recognized and converted into the amino acid sequence with the help of the Ribosome.
  • The amino acid sequence folds to give rise to the protein.

Linked the family with community sources for aid.


Besides nursing care, the nurse would make sure that interdisciplinary members of the team were involved, such as, the doctors' nutritionist, community worker, or resources, and provide a supportive environment for the family, and the client. The chaplain may be of support for the infant, or family may not be present. the bright room is overly stimulating to the withdrawing infant, and feeding is basic care.



Hope this helps.

Trees use narrow tubes to transport water upward. Which property of water allows the water to rise in these narrow tubes?
cluponka [151]

Answer:

C. Cohesion of molecules

Explanation:

Cohesion is the interaction of molecules of the same substance together. By the force of cohesion if two drops of water come together they form one. Water has high rates of cohesion due to hydrogen bonds.  

This phenomenon also called surface tension and is what allows small insects to stand on water.

Cohesion along with adhesion of water to the walls of the narrow tube generate what is called capillarity. This allows liquids to ascend inside the narrow tubes. As long as the cohesion is less than the adhesion, the liquid will rise until both forces are equal.

The only phylum in the group Parazoans is ________. A. Porifera B. Cnidaria C. Lophotrochozoa D. Ctenophora E. Ecdysozoa
ludmilkaskok [199]

Answer:

A. Porifera

Explanation:

Parazoan is a sub-kingdom of animal consisting only of the phylum of sponges (porifera), having two tissue layers only and lacking a nervous system and true digestive cavity.

They have certain characteristics like: sponges are marine, but there are some freshwater sponges that enjoy their water without salt. Most sponges do not have any type of symmetry, but some are radially symmetrical and they come in a variety of shapes, colors, and sizes, they are multicellular, heterotrophic and lack cell walls. Unlike other organisms, sponges lack true tissues and organs.

The mesohyl functions as an endoskeleton in most sponges, and is the only skeleton in soft sponges. This mesohyl is stiffened by mineral spicules, by spongin fibers or both.

An amoeba uses a sugar molecule during metabolic activity. It loses energy to the environment as a result. The transformation of
34kurt

Answer:

Option B, chemical energy to thermal energy

Explanation:

All living organism feed on food that contains energy in the form of chemical energy. Once the food is intake and processed for fulfilling energy requirement of all metabolic processes with in a cell, the remaining energy is released as heat (thermal energy). Thus, an amoeba while consuming a sugar molecule converts chemical energy with in the sugar to thermal energy in the form of energy molecules.

Hence, option B is correct
