<em>adaptive radiation formed many new land plant species</em>
This is the era of recent life that began about 66 million years ago and continues today. It includes the first appearance and Homo sapiens about 400,000 years ago. <span />
Answer:mismatch repair
Explanation:proof reading is a process through which the mistakes that were made during the process of replication of DNA are corrected and if they are corrected after replication of DNA the process is called mismatch repair .
DNA Mismatch repair also called as MMR is a system for recognizing and repairing the DNA for unwanted insertion, deletion, and mis-incorporation of bases that can arise during DNA replication and recombination, as well as repairing some forms of DNA damage.
Answer:
The option which does not describe the generalizations in the cerebral cortex is <u><em>b. The hemispheres are exactly equal in function.</em></u>
Explanation:
The cerebral cortex is an exclusively grey matter which makes 40% of the mass of the brain. It has areas for motor neurons and sensory neurons to enter into it and it controls actions like thinking, understanding etc.
The cerebral cortex has two hemispheres; the left hemisphere and the right hemisphere. Each side has different functions to perform.
The cerebral cortex is divided into four lobes and each lobe performs different functions.
Answer:
Group behavior, also known as collective behavior, <u>can increase the chances for a species to survive and reproduce because they can rely on each other to accomplish behaviors that are crucial for their survival, such as hunting, migrating, and breeding.</u>
Explanation:
According to ethologists, social species highly depend on the members of their own group for survival. One perfect example is the case of <u>schooling fish</u>. These small species of fish gather in a whole large group and navigate long distances while looking for food. Researchers from Princeton University <u>discovered that their orientation capabilities increased when more individuals joined the group, making them more responsive to the environment.</u>
<u />
Moreover, there have been numerous sources of evidence that demonstrate that <u>orcas (killer whales)</u><u>,</u> which are extremely social creatures<u>, create large pods of around 20 to 30 individuals and 'plan' strategies to hunt. Also, older females swim along younger individuals to teach them hunting skills that are crucial for their survival.</u>
<u />
In addition, <u>herbivores</u>, like zebras, <u>are usually found in large groups because it lowers the possibilities of being individually targeted by apex predators, such as lions.</u>
<u />
Recently, researchers have also discovered that <u>migrating species</u><u> often rely on each other to improve their migrating capabilities by producing or generating social cues that allow them to improve their orientation or in cases when environmental conditions get tough</u> (Source).
In conclusion, these lines of evidence show that social organisms who travel in groups rely on all members to carry out important behaviors that, without them, would provoke an important decline in their populations because they wouldn't be able to reproduce or feed individually as successfully as they would with the 'help' of the members of the group.
