Answer:
substitution - a base was changed
Explanation:
The nucleotide sequence CTT was changed to the sequence CAT. The T was substituted with an A. This changed the encoded amino acid from Glu to Val.
An insertion is where an additional base is added (e.g. if the sequence changed from CTT to CATT)
A deletion is when a base is lost (e.g. if the sequence changed from CTT to CT)
Answer:
the answer is C
Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use
As trees takes in carbon dioxide and gives out oxygen, it is almost similar to how our lungs work in our respiratory system. As you know, lungs remove carbon dioxide from our body and transports oxygen in order for us to survive. So the tropical rainforests gives out oxygen for our survival needs, which is somewhat similar.

These 2 identical rods of DNA are called sister chromatids, and they are held together at the centromere.
The sporophyte of <u>whisk ferns</u> consists of evenly forking photosynthetic stems that lack roots and leaves.
Whisk ferns are the elementary and simplest vascular plants.
They contain small-sized protuberances which are called ' enations.'
In these plants, a vascular system is present in the center through which the transport of nutrients and other fluids takes place.
Moreover, roots and leaves are absent in these plants and are composed of forklike stems.
To put it simply, these plants have hair-like structures that are part of the rhizomes. These structures are called rhizoids.
