The phospholipid molecule has two parts, the polar end and the bipolar end. True or False?

1 answer:

4 0

False; a phospholipid molecule has a "head" and two "tails"

Basically it has a polar end with a phosphate group attached, and a nonpolar end that has two fatty acid "tails" or chains.

Hope this helps :D

Pachacha [2.7K]

<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.

Fats supply energy, cushion vital organs and protect them from injury, add flavor to food and move through the _______ system sl

Mademuasel [1]

Answer: Digestive system

Explanation:

Fat carries out many functions in the body of organisms. They are great source of energy especially when less amount of glucose is present in the body. They act as pads to many structures in the body.

Their roles in adding flavor to food is highly emphasized and their vehicular role in moving food in the gut have helped greatly in acquisition of nutrients by organisms

Jobisdone [24]

Answer:

The correct answer is

- Carbon dioxide, ATP, and NADPH,

- In the stroma of the chloroplast.

Explanation:

The product of the light-dependent reaction that uses in the Calvin cycle or the light independent cycle. Calvin cycle is the light independent cycle that involves the production of the glucose by converting carbon dioxide and other products of light reaction.

The light-independent reaction takes place in the stroma a fluid-filled region of the chloroplast in the photosynthetic organisms.

Thus, the correct answer is -

- Carbon dioxide, ATP, and NADPH,

- In the stroma of the chloroplast.

Based on duration on persistence, how are diseases catagorised?

Sidana [21]

In the topographic classification, diseases are subdivided into such categories as gastrointestinal disease, vascular disease, abdominal disease, and chest disease. ... In the anatomic classification, disease is categorized by the specific organ or tissue affected; hence, heart disease, liver disease, and lung disease.
