Answer:

Climate change has been described as one of the biggest problems faced by humankind. Carbon dioxide is is the primary driver of global warming. Prof Joanna Haigh from Imperial College London explains why this gas has played a crucial role in shaping the Earth's climate.

Carbon dioxide (CO2) has been present in the atmosphere since the Earth condensed from a ball of hot gases following its formation from the explosion of a huge star about five billion years ago.

At that time the atmosphere was mainly composed of nitrogen, CO2 and water vapour, which seeped through cracks in the solid surface. A very similar composition emerges from volcanic eruptions today.

As the planet cooled further some of the water vapour condensed out to form oceans and they dissolved a portion of the CO2 but it was still present in the atmosphere in large amounts.

A random mutation occurs and the GGA codon is changed to GGU. What effect does this substitution have on the amino acid being ca
salantis [7]

Answer:

Instead of arginine codon, proline condon would be coded.

Explanation:

GCA encodes codes for glycine while on the other hand codon to GGU, GGC, or GGG encodes for glycine.

This substitution will lead to generation of complementary code “Proline” in the complementary mRNA or DNA strand.  

The codon CCT, CCC, CCA, CCG encodes for proline. If this mutation would not have occurred then Arginine would have been encoded in the complementary codon  with base structure of CGT, CGC, CGA, CGG

When we say an animal has an "open circulatory system," this means that: movement of the animal is solely responsible for moving
adoni [48]
An open circulatory system simply means that the blood flows out of vessels and into the spaces or sinuses. Invertebrates, insects and crustaceans has an open circulatory system where pump blood goes into a hemocoel and diffusing back to the circulatory system between cells. In other animals, the heart pumps the blood into the body cavities, spaces or sinuses, where the blood surrounds the tissues.
