Natalka [10]

Answer:

Sea otters affected biodiversity because they control the populations of sea urchins, which endanger kelp forests. Kelp forests are important because they convert sunlight to living material, and they also provide food and habitat to sea creatures. Kelp is important in sustaining the diversity of ecosystems. Additionally, sea otters may also be accountable for the large size of abalones in California.

Speciation is the process by which new species are formed. Which of the following circumstances is most likely to lead to specia
trapecia [35]

Answer is A. A population becomes separated by environmental factors into two groups that do not reproduce with one another.

When a population of a species become geographically separated then gene flow between them stops. Over a period of time, the population may become genetically different in response to the natural selection due to different environments. Selection and genetic drift will act differently on these two separated populations. This will results into two separate species. This type of speciation is called allopatric speciation.

Which is the role of restriction enzymes?
dezoksy [38]
Restriction enzymes and or restriction endonucleases are involved at recognizing specific sequence of nucleotides and cutting or splicing them at appropriate regions to produce fragments that can either be sticky ends or blunt ends depending on where they cut and the nature of nucleotides involved within the fragments. They play an important role in genetic engineering, as geneticists can use them for placing into extra chromosomal information and or content of plasmids in certain bacteria, from other sources, for instance antibiotics, grow and or produce many individual colonies of bacteria, isolate them and one would have many sequences for instance that can code for an antibiotic that can be extracted and used further. Assuming the bacteria's plasmid can take in that sequence.

bezimeni [28]
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.
