Answer:
C. A-T rich; initiator
Explanation:
Replication origins have A-T rich DNA sequences that attract initiator proteins.
Replication origin is the DNA sequence where replication is initiated in a genome. The replication origin sequences is rich in adenine (A) and thymine (T) bases because it is easier to break the bonds between the bases compared to the bonds between guanine and cytosine. adenine (A) and thymine (T) bases have two bonds joining them as against three bonds between guanine and cytosine
The initiator proteins recognizes DNA sequences in the replication origin and helps to initiate DNA replication.
Answer:
The answer is A. Invented SCUBA
Explanation:
- Emile Gagnan and Jacques Cousteau were engineers who invented the first SCUBA device, the Aqua-Lung.
- Gagnan's most important contribution to this discovery was his theory that a valve commonly used in gas generator engines would be useful in regulating air supply under water in varying pressures.
Answer:
Photosythesis is the process of which plants make oxygen and also gulcose. This process happens when the plants uses their roots to taken in water in the ground and also anchor themselves in the ground. The stomata in the leaves take in carbon dioxide and the sunlight and using theses materials the plants create glucose and oxygen we breath.
Precipitation, soil, temperature, humidity, and altitude
