Are stars luminous or non-luminous? Explain your answer.
rusak2 [61]

Answer:

Both a torch and a star are considered to be luminous objects. In order for us to see an object that is non-luminous, it must reflect some of the light it receives from a luminous source, such as the Sun.

The amount of energy required to heat 0.5 kilograms of water until the temperature increases 12° C is about
Bogdan [553]

Answer:

Q = 25104 / 4.184 = 6000 Calories or 6 Kcal

Explanation

Energy can be calculated by the equation

Q = m x Cp x delta T

where

m = mass = 0.5 kg

Cp = specific heat of water = 4184 J

Delta T = 12 degrees

Multiplying all

Q = 0.5 x 4184 x 12 = 25104 Joules

Converting it to Calories

Q = 25104 / 4.184 = 6000 Calories or 6 Kcal

How are primary consumers different from secondary consumers
Thepotemich [5.8K]

Answer:

Answer:

<h2>Primary consumers are  those animals that depend on or they eat primary producers. </h2><h2>Secondary consumers are those that eat mainly primary consumers. </h2>

Explanation:

Primary Consumer: A primary consumer is an organism that directly eat primary producer ( plants). They are usually herbivores that eats autotrophic plants, autotrophic plants produce food through photosynthesis. Primary consumer are heterotrophic.

Example: Goat, cow and rabbit.

Secondary consumers: Secondary consumers depends mainly on primary consumers for their food  requirement. Secondary consumers are carnivores  as well as omnivores.

Example;  Owls, bears, lions and humans etc.

From a chemical view, how is an amino acid is being recognized by its specific aminoacyl tRNA synthetase?
hammer [34]

During translation, rRNA and tRNA read mRNA in 5´ to 3´ direction. According to the codons being readen, tRNA transfers the correct amino acids to build the polypeptide chain. A codon is a short sequence of three nucleotides that store the genetic information for the aminoacids´ assembly.

Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid through the action of the aminoacyl-tRNA synthase enzyme. The whole complex, amino acid + enzyme + tRNA is named aminoacyl-tRNA.        

Each tRNA is recognized by a specific aminoacyl-tRNA synthase enzyme. The enzyme is also capable of recognizing a specific amino acid. Let us say, for instance, that <em>tRNA is specific for phenylalanine.</em> The molecule is attached to the <em>enzyme that is specific for that tRNA(Phe)</em>. Then, when the enzyme and tRNA(Phe) are together, they get to <em>find phenylalanine</em>. The <em>enzyme links the aminoacid to the RNA</em>. Once the whole complex is formed, the <em>tRNA gets to pair its anticodon with the mRNA codon</em>. This is,

  1. Recognition of enzyme and the specific tRNA(aa) ⇒ aa being aminoacid
  2. Recognition of enzyme and the specific aminoacid
  3. Linkage of the aminoacid to RNA by the enzyme action
  4. Pairing of tRNA anticodon to mRNA codon.

Considering that there are twenty amino acids available, there are also twenty complexes of aminoacyl-tRNA, one for each amino acid. Each of the mRNA codons represents one of the 20 amino acids used to build the protein. Each amino acid can be codified by more than one codon. Of the total 64 codons, 61 codify amino acids, and one is a start codon. The left three codons are stopping translation points.

tRNA decodes genetic information from the nucleotidic sequence in the mRNA molecule and allows amino acids to align composing the new protein.  

Once the new peptidic link joins, placing together the new amino acid to the growing peptidic chain, the binding between the amino acid and the tRNA molecule breaks. The tRNA is now free to join another amino acid and repeat the cycle.

In conclusion, a specific aminoacyl-tRNA synthase enzyme recognizes a tRNA, which is also specific for a certain amino acid. When together, the enzyme recognizes the amino acid and links it to the RNA. The whole complex is known as aminoacyl-tRNA. Once the tRNA is joined to its amino acid, it gets to pair a codon of mRNA to add that amino acid to the new synthesizing protein.

What is the important of water​
crimeas [40]

Answer:

Our bodies use water in all the cells, organs, and tissues, to help regulate body temperature and maintain other bodily functions. Because our bodies lose water through breathing, sweating, and digestion, it's crucial to rehydrate and replace water by drinking fluids and eating foods that contain water.
