<h3><u>Answer;</u></h3>
DNA
<h3><u>Explanation;</u></h3>
- A nucleic acid is DNA that contains heredity information used in the development as well as functioning of all known organisms, with the exception of some viruses.
- DNA is the carrier of our genetic information, and is passed down from generation to generation. All of the cells in our bodies, except red blood cells, contain a copy of our DNA.
Answer:
DNA replication is faster and microscopic in size, smaller than eukaryotic cell.
Explanation:
The three domains of life are archaea, bacteria and eukarya. The two main biological division are prokaryotes and eukaryotes. The organisms that lacks the complete nucleus are included in prokaryotes.
The DNA replication is quite fast in prokaryotes as compared to eukaryotes because of small genome size, transcription is coupled with the translation and no post transcription modification is present in prokaryotes. The size of prokaryotes is quite small as compared with eukaryotes and shows the fast rate of diffusion.
Thus, the answer is option (a) and (c).
Answer:
0.36g
Explanation:
Given parameters and conversion to standard unit
To solve this problem we must assume ideality
Volume of N₂H₄ = 350mL = 0.35dm³
Temperature of container = 50°C = 50 + 273 = 323K
Pressure = 885torr;
760torr = 1atm
885torr = 
= 0.86atm
Unknown:
Mass of the compound = ?
Solution:
The mass of the compound can be derived using the expression below;
Mass = number of moles x molar mass
molar mass of N₂H₄ = 2(14) + 4(1) = 32g/mol
To find the number of moles;
PV = nRT
n = 
P is the pressure
V is the volume
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
n = 
= 0.01mole
So,
Mass = 0.01 x 32 = 0.36g
Answer:
Compare the carboniferous period to the Devonian period is compared below in details.
Explanation:
In the Devonian Period, woods and land plants developed and vertebrates performed their presentation. Four-legged vertebrates developed during the Carboniferous Period, which created an improvement in the number of land-based bodies. The climate of the continental inland sections was very heated through the Devonian Period and usually quite dry while woods and land plants developed during the Carboniferous period.
Gaseous exchange is fundamental in aerobic organisms because oxygen is required to carry out cellular respiration.
<h3>What is cellular respiration?</h3>
Cellular respiration is a series of chemical reactions by which aerobic organisms interchange oxygen and carbon dioxide with their surrounding environment.
During cellular respiration, oxygen is consumed to generate ATP and carbon dioxide is released.
In conclusion, gaseous exchange is fundamental in aerobic organisms because oxygen is required to carry out cellular respiration.
