Answer:
6.0 x 10 to the power of 23
By the process of respiration and photosynthesis; carbon dioxide is obtained and also carbon dioxide in huge amount is produced from the industries which enters in the atmosphere. Carbon dioxide is one of the greenhouse gas.
Greenhouse gases are those gases which are able to trap the radiation in the atmosphere and which keeps Earth warmer. Thus, high levels of carbon dioxide gas keep the temperature of Earth warmer.
Answer:
The three ways to in which the hydrocarbons are represented are;
a. The ball and stick model
b. Condensed structural formula
c. Skeletal structure
The molecular formula are
a. C₇H₁₆
b. C₆H₁₄
c. C₅H₁₂
Explanation:
a. The ball and stick model of organic compounds, displays the atoms and bonds in three dimensions, representing the atoms by spares and the bonds by rods
b. The condensed structural formula are similar to the structural formula with the difference that the formula is written in a linear fashion which conserves space and increases ease of writing and are written out faster.
c. In the skeletal structure diagram, the atoms are of the organic compound are combined together in the structural drawing of the essential features of the organic compound. In essence, a skeletal structure, depicts the skeleton of a compound as it is made up of the molecule's skeletal atoms.
Answer:
1.) Are tightly coiled bundles of DNA
2.) Carry many genes
3.) Are found inside the nucleus of eukaryote
4.) Can be used to diagnose genetic disorders
Explanation:
A chromosome is a thread-like structure made up of DNA. The chromosomes are made of DNA which are tightly coiled around protein.
Chromosomes carry hundreds and thousands of genes. The number of genes in a cell outnumbers the number of chromosomes.
In eukaryotic cells, all the chromosomes are found inside the nucleus of eukaryote.
The chromosomes and DNA can be examined so as to diagnose genetic disorders.
