Out of the following given choices;
A. theory that fish and mammals have a common ancestry
B. theory that the first organisms on Earth were heterotrophs
C. close relationship between fish and mammalian reproductive patterns
D. close relationship between humans and annelids
The answer is A. Many embryos of the kingdom Animalia share similarities in the early stages depicting that they share a common ancestor. The gill slits is one example. They diverge in later stages to become Pharyngeal in the human embryo, while they differentiate into gills in fish.
The equation for photosynthesis is given as:
6CO₂ + 6H₂O ----> C₆H₁₂O₆ + 6O₂
<h3>Photosynthesis</h3>
Photosynthesis is the process by which green plants manufacture their food from carbon dioxide and water in the atmosphere using sunlight as an energy source.
Carbohydrates are produced while oxygen is given off as a by-product in photosynthesis.
During photosynthesis, the energy from the sunlight is trapped by the chlorophyll found in the chloroplast and used to energize the reactions involved in photosynthesis.

The correct answer is "increased activity of the right hippocampal formation".
Hippocampus is a brain area which is part of the limbic system and is located below the cerebral cortex. Humans have two hippocampi, one in each side of the brain. Hippocampus is responsible for the formation of long-term memories, by participating in the consolidation of short-term to long-term memory. It also plays a very important role in spatial memory and orientation.
The task that this experienced cab-driver is asked to perform is related to spatial navigation and orientation abilities. The right hippocampus has been shown to participate in the formation of memory for locations in specific environments, while the left hippocampus has been shown to be involved in autobiographical and episodic memory. As a result, the PET scan will show an increased activity of the right hippocampus.
Answer:
They are called alleles.
Explanation:
Different versions of a gene are called alleles. Alleles are described as either dominant or recessive depending on their associated traits.
