Answer:
Compared to adults, when learning a second language, children will do which of the following: more likely to learn from smaller amounts of input, less sensitive to feedback, less likely to use explicit strategies, more likely to learn from large amounts of input.
The period of human evolution has coincided with environmental change, including cooling, drying, and wider climate fluctuations over time. How did environmental change shape the evolution of new adaptations, the origin and extinction of early hominin species, and the emergence of our species, Homo sapiens? (‘Hominin’ refers to any bipedal species closely related to humans – that is, on the human divide of the evolutionary tree since human and chimpanzee ancestors branched off from a common ancestor sometime between 6 and 8 million years ago.)
How do we know Earth’s climate has changed? How quickly and how much has climate changed? One important line of evidence is the record of oxygen isotopes through time. This record of δ18O, or oxygen stable isotopes, comes from measuring oxygen in the microscopic skeletons of foraminifera (forams, for short) that lived on the sea floor. This measure can be used as an indicator of changing temperature and glacial ice over time. There are two main trends: an overall decrease in temperature and a larger degree of climate fluctuation over time. The amount of variability in environmental conditions was greater in the later stages of human evolution than in the earlier stages.
It is known that the increase or decrease of hormones causes a change in the sleep, as is the case of <u>melatonin</u>.
<h3>How do
Hormones influence
Sleep?</h3>
When a person goes to sleep at night, her body must increase the levels of melatonin cortisol in the blood so that the person feels tired and can sleep.
For its part, growth hormone at night has a gradual decrease, which causes the body to work less during sleep and allows the person to rest during their REM phase.

Answer:
Attention deficit hyperactivity disorder (ADHD)
Explanation:
Attention deficit hyperactivity disorder (ADHD) is a chronic condition which includes trouble with concentration, hyperactivity and impulsiveness.
ADHD sometimes starts in childhood, and can continue in adulthood. This may lead to poor self-esteem, unstable relationships and school or job difficulties, it mostly affects children and teenagers, which can persist into adulthood. The most frequently diagnosed childhood psychiatric illness is ADHD. Children with ADHD are potentially hyperactive and unable to control their impulses. Or, they may have problems paying attentive.
People with ADHD may also have trouble focusing their attention on a single task or sitting still for long periods of time.
