Answer:
Neuroscientists conducted research with taxicab drivers in London and found that taxicab drivers, who are required to have a tremendous amount of spatial and geographic knowledge, had a larger <u>hippocampus</u> than other drivers.
Option D.hippocampus
Explanation:
Hippocampus is concerned with following important functions:
- Storage of new information in the memory (converting short memories into long memories)
- Comparing sensory information with what the brain expects about the world
- Enabling us to form spatial memories for investigating the environment
As the geographic knowledge and spatial knowledge is being stored in the hippocampus, the taxi driver surely have greater hippocampus than other drivers.
Answer:
Natural selection by directional selection, was the driving force of evolution at work. The purple flowers parents were able to withstand the selective pressure and therefore emerged from completions with other flowers from previous generation, thus their dominance follow directional selection. This was the trait inherited by their offspring, the dominant purple
The gene pool of purple flower will be large; because of dominance in expression with each successive generation in both homozygote and heterozygote state, and therefore higher frequency of expression compared to the white flowers.
The frequency of allele depends on the rate expression of the allele in the population. Thus, the dominant purple flowers have high frequency of expression compared to the recessive white flowers which can only express itself in homozygote recessive state
(D) It is especially important to protect biodiversity hot spots.
<h3>What is Biodiversity?</h3>
The variety and variability of life on Earth is referred to as biodiversity or biological diversity. A measure of variety at the genetic (genetic variability), species (species diversity), and environmental (ecosystem diversity) levels is called biodiversity.
Because of the warm environment and high primary productivity in the area close to the equator, the tropics typically have higher levels of biodiversity than other parts of the planet. Less than 10% of the earth's surface is occupied by these tropical forest ecosystems, which are home to 90% of all species. The mid-latitudinal belt of all oceans and the shores of the Western Pacific, where the sea surface temperature is highest, typically have higher levels of marine biodiversity. The variety of species exhibits latitudinal variations.
