Answer:
Thymine is used in replication while uracil is used in transcription.
Explanation:
<em>New cells can only be created after transcription has taken place. Replication results in mRNA strands while transcription creates new DNA. Transcription happens outside the nucleus and replication happens inside the nucleus. Thymine is used in replication while uracil is used in transcription.</em>
DNA replication is a process whereby DNA makes a copy of itself while DNA transcription is a process whereby a messenger RNA is synthesized from a DNA strand.
Both processes involve the building-up of nucleotides or purine.pyrimidine bases. Replication involves building up of cytosine, guanines, adenine, and thymine bases while in transcription, the thymine base is replaced by uracil base.
Hence, the correct answer is that <u>Thymine is used in replication while uracil is used in transcription.</u>

Answer: Option B
Pigs wallow in the mud to cool themselves down.
Explanation: Pigs' skin contains lots of fats, and fats serves as thermal insulator during cold (low temperatures); unfortunately, this feature turns becomes a disadvantage during heat (high temperatures). Hence, pigs frequently wallows in the mud (or any nearby cool water place) - to reduce their body temperature.
<span>There are three basic chemical components of DNA - 1. Four "Nucleic acids", 2. Deoxyribose sugar, and 3. Phosphate backbone. The overall shape of the molecule is a double-stranded, double helix. It looks a bit like a spiral staircase wrapped around a spiral staircase. Phosphate groups outside, nucleic acids inside the helix,</span>
They are found in the center of the osteon within a long opening called the Haversian canal.
Answer: Mars receives more insolation than Saturn.
Explanation:
Insolation is defined as the exposure to the Sun's rays.
Mars is the 4th planet in Our solar system and is near to the Sun.
Saturn is the 6th-planet in Our solar system and is far from the Sun.
Insolation is directly proportional to the planet's distance from the Sun.
So, the exposure of Sun's rays is more to the planet which lie close to the Sun.
As, Mars is close to the sun than Saturn. Hence, it will receive more insolation than Saturn.
