Write a summary statement for saturated fats including whether they are solids or liquids at room temperature and weather they have all single carbon-to-carbon or at least one carbon-to-carbon bond

Answers

Answer:

A saturated fat is a type of fat in which the fatty acid chains have all or predominantly single bonds. A fat is made of two kinds of smaller molecules: glycerol and fatty acids. Fats are made of long chains of carbon atoms. Some carbon atoms are linked by single bonds and others are linked by double bonds. Double bonds can react with hydrogen to form single bonds. They are called saturated because the second bond is broken and each half of the bond is attached to a hydrogen atom.

Explanation:

Answer:

saturated fats consists of single covalent bond and they are solid at room temperature and their melting point increases with increasing chain length

Which statement best describes the human immunodeficiency virus (HIV) that has been shown to cause AIDS in humans?

Answers

The first stage of HIV infection is known as the acute stage. The body responds by producing HIV antibodies and killer T- cells which are special lymphocytes that seek out and destroy invading pathogens such as viruses and bacteria. Two to four weeks after infection, the immune system launches an attack against HIV using these antibodies and killer T-cells, significantly reducing HIV level on blood. A percentage of the viruses however escapes this onslaught by hiding in other cells and continue to multiply.

A cell turns glucose from thefood we eat into energy for our
body to use. What cell function
does this describe?


Answers

Answer:

\boxed {\boxed {\sf Cellular \ respiration}}\n

Explanation:

The process of cellular respiration occurs in the mitochondria of cells. It goes through 3 stages: glycolysis, the citric acid/Krebs cycle, and the Electron Transport Chain.

The equation is:

C_6H_(12)O_6+6O_2 ->6CO_2+6H_2O+38 \ ATP

In this aerobic process (requires oxygen), glucose (C₆H₁₂O₆) from the food animals eat or produced from photosynthesis and oxygen are converted into carbon dioxide, water, and useable energy (ATP).

So, the cell function described is cellular respiration.

Read the passage.(1) New York City has many tourist attractions, but one attraction stands head and shoulders above the rest. (2) It is the Statue of Liberty, also known as Lady Liberty. (3) Lady Liberty is a woman holding a torch, it represents freedom. (4) The statue is 305 feet tall, including the pedestal on which Lady Liberty stands.
Which among the sentences contains a comma splice?


A. sentence (1)
B. sentence (2)
C. sentence (3)
D. sentence (4)

Answers

Sentence (1) contains a comma splice. Therefore, option (A) is correct.

What is comma splice?

A comma splice is an error in grammar that occurs when two independent clauses (complete sentences) are joined by a comma, without the use of a coordinating conjunction (such as "and" or "but"). This error can occur when a writer is trying to connect two ideas or sentences, but does not use the proper punctuation to do so.

In sentence (1), the clauses "New York City has many tourist attractions" and "one attraction stands head and shoulders above the rest" are both independent clauses, but they are joined by a comma instead of a coordinating conjunction. This creates a comma splice.

#SPJ2

A comma splice is basically a comma fault which means- when two independent clauses are joined by a comma to make one complete sentence. And an independent clause is a clause that can stand alone as a sentence.

So, here in the passage- Option C is correct one.

Lady Liberty is a woman holding a torch, it represents freedom. This sentence can be successfully broken into two complete sentences. Like- Lady Liberty is a woman holding a torch. It represents freedom.

Which example best demonstrates the importance of having knowledge of evolutionary relationships?

Answers

The correct answer for the question presented above is organ transplantation between species. Having knowledge of evolutionary relationships help in successfully transplanting organs to different species based on the fact that some species share similar DNA characteristics. This allowed us to discover that transplant between species is possible.

What is the mechanical advantage of a machine that applies a force of 1000 N to an object when a force of 500 N is applied to the machine?

Answers

The mechanical advantage of the machine in the problem is 2. By definition, the mechanical advantage of a machine is equivalent to the ratio of its output force to its input force. Since it applies a force of 1000 N to an object, that is its output. Also, since a 500 N force is applied to the machine, that is its input. So 1000/500 = 2.

Answer: 2

Explanation:

  • The mechanical advantage of a machine is defined as the amplification of the force produced when using a machine or a tool.
  • In mathematical terms, it is the ratio of the output force to input force and, the formula is :

       MA = Fo/Fi

       Where MA= mechanical advantage

       Fo= Output force

        Fi = input force.

  • According to  the question, Fo= 1000N

       Fi= 500 N

  • Therefore, MA= 1000/500 = 2
