Which statement best describes a direct result of damage to a phospholipid bilayer

Answers

The options attached to the question above are given below:

A. The balance of ions inside a cell will be disrupted and proteins could leak out because the phospholipid bilayer forms the cell membrane.

B. Energy storage will be disrupted because the phospholipid bilayer is responsible for storing energy in the body.

C. Chemical messages could not be sent to different parts of the body because the phospholipid bilayer forms hormones.

D. A person would be vulnerable to disease because the phospholipid bilayer helps to fight infections in the body.

ANSWER

The correct option is A.

The phospholipid bilayer is found in all cell membranes. It functions by providing a critical barrier which signifies the boundary of cells and allow only specific particles to pass into the cells. Damage to the phospholipid bilayer result in disturbance of the ions that are inside the cells, the proteins and other components of the cell could also leak out. Beside these, particles, that are normally prevented from entering into the cells can easily gain entrance into the cells.

Which phrase best defines a galaxy? Tightly packed group of older stars large grouping of more than two stars loose, disorganized star cluster held together by gravity large collection of stars, gas, and dust held together by gravity

Answers

Answer: Large collection of stars, gas, and dust held together by gravity.

Explanation:

  • The name galaxy has been derived from the word galaxies which is a Greek word meaning milky.
  • In simple words a galaxy is a collection of a large number of stars, however, to be more precise a galaxy is a gravity-bound collection of stars, dust, gas, dark matter and stellar remnants.
  • There are different types of galaxies found in various shapes and size, some of the most common shapes being elliptical, irregular and spiral.
  • An example is the milky way galaxy that contains our solar system.

Galaxy is a collection of millions or even billions of stars, gas, and dust held together by force of gravity, so the answer is: ´´a large collection of stars, gas, and dust held together by gravity´´.

During the process of steel production, the flaws in steel casting are detected by a. ultrasonic vibrations.
b. infrasonic vibrations.
c. resonant vibrations.
d. longitudinal vibrations.

Answers

During the process of steel production, the flaws in steel casting are detected by A. ultrasonic vibrations. Ultrasonic vibrations are sound waves that have a frequency higher than human hearing. These sound waves are sent through a steel casting such as a part of a machine engine. If there are any flaws in the casting, the quality controller will be able to pinpoint where the flaw is and to determine the flaw's shape and size. This technology is integral to the manufacture of structurally sound steel castings

Summarize how protein molecules are made through transcription and translation. Where do these processes take place?

Answers

Answer: Protein molecules are made through the transcription of a DNA strand into an mRNA strand and the translation of the mRNA into a protein. Transcription takes place in the nucleus of the cell while translation takes place in the ribosome.

Explanation: Transcription is a process of copying the genetic message encoded in a DNA strand into a messenger RNA (mRNA). This process is the first step in protein synthesis and takes place in the nucleus. It is catalyzed by an enzyme known as RNA polymerase. The synthesized mRNA then leaves the nucleus and enters the ribosome where translation occurs. During translation, the mRNA passes through the ribosome complex three nucleotides at a time where the codon is read and the corresponding amino acid coded for is fetched and attached to the peptide chain by the transfer RNA (tRNA). Translation starts when the ribosome encounters the start or initiation codon on the mRNA molecule. The start codon is AUG and it codes for methionine. Translation stops when the ribosome encounters the stop or termination codon. There are three termination codons and they are so named because they do not code for any known amino acid. The termination codons are UAG, UAA and UGA.
