Carbon 14 and Uranium 238 are not used together to determine fossil ages.
Cyanobacteria are the major force of the Great Oxygenation Event around 2.35 billion years ago. The organisms that evolved photosynthesis changed the composition of the atmosphere to mainly oxygen. This changed the dynamic of life on earth by allowing organisms to also exist on land. This is because it was possible for ozone to form and reduce the lethal UV rays from the sun reaching the earth's surface to destroy genetic material.
Answer:
O Feathering
Explanation:
Feathering refers to the technique by which large flowers are cut into small pieces, which are then used to create smaller flowers. Feathering consists of removing the petals and wire the petals in order to create a smaller form. Carnations are a type of flower in which feathering is applied. This process was widely used by florists in the past but currently is uncommon due to the excessive time and labor involved in this technique.
Answer:
Lateral Hypothalamus
Explanation:
According to the hunger researchers' initial assumption lateral hypothalamus is that part of the brain which regulates intake of food and metabolical activities like metabolical regulation of peptides like the orexins melanin-concentrating hormone. It is that part of the brain that plays a key role in the ingestive behavior regulation.
The lateral hypothalamus system initiates physical and cognitive processes like it promotes arousal and feeding behavior, metabolism, regulates body temperature, BP, etc. and when stimulated it results in the feeding behaviour in animals as they begin to eat.
