Make a decision about the molecule NaHCO3 classification organic or inorganic
motikmotik

<u>Answer:</u>

NaHCO_{3} is an inorganic compound.

<u>Solution:</u>

  1. Firstly, all the known definitions of organic compounds excludes Carbonic acid and it's salt from organic compounds except if 'C' is present in the cation.  
  2. Secondly, Sodium is a metal which organic compounds cannot posses as a compound.  
  3. Lastly, there is absence of C-H bond which is present in all the organic compounds.

Hence, we can conclude that NaHCO_{3}is an inorganic compound though there is presence of Carbon atom in it.

The diagram below shows some of the steps in protein synthesis.
Zinaida [17]

Answer:

According to the diagram shown, the section of DNA used to make the mRNA strand is known as a gene (option 2).

Explanation:

Gene consists of a DNA fragment that codes for the synthesis of a specific protein that defines the structural or functional trait of a living being.

When DNA is transcribed into mRNA, each section of transcribed DNA is part of a gene. The information travels to ribosomes in the cytoplasm where protein synthesis occurs.

A complete DNA molecule forms a chromosome, which contains the genes with information to define specific traits of a species.

The other options are not correct because:

<em>     1.Carbohydrate is a biomolecule that is not involved in the genetic process. </em>

<em>     3. Ribosome is where protein synthesis occurs. </em>

<em>     4. Chromosome is the complete DNA molecule.</em>

(Does heating water allow it to dissolve more sugar)? What is the Dependent Variable, What is the Independent Variable?​
tino4ka555 [31]

Answer:

yes

independent - temperature

dependent - amount of sugar dissolved

Explanation:

When water molecules are heated they move faster and collide more with the sugar molecules. These collisions transfer energy to the sugar molecules. Energy is needed to break bonds. The bonds holding the sugar molecules together or more likely to be broken.

The amount of sugar dissolved is dependent on the temperature of water.

Alternation of generation
Nastasia [14]

Answer:

The answer to this question is given below in this explanation section.

Explanation:

                    "Alternation of generation"

Alternation of generations is the type of life cycle that occurs in those plant  and algae in the archaeologist and the heterokontophyta that have distinct haploid sexual and diploid asexual stages.In these groups a multicellular haploid gametophyte with n chromosomes alternates with a multicellular diploid sporophyte with 2n chromosomes made up of n pairs.A mature sporophyte produces haploid spores by meiosis a process which reduces the number of chromosomes to half from 2n to n.

Two haploid spores germinate and grow into a haploid gametophyte.At maturity ,the gametophyte produces gametes by mitosis which does not alter the number of chromosomes.Two gametes from different organism of the same species fuse to diploid zygote,which develop into a diploid sporophyte . This cycle from gametophyte to sporophyte in the way in which all land plant and many algae undergo sexual reproduction.
