Shallow groove on the surface of the cortex is called sulcus.
Cortex means the outer layer of an inner organ. The outer layer of the cerebrum is called cerebral cortex, where cerebrum occupies the biggest part of the brain. A human being has four lobes of the cerebral cortex which include temporal lobe, parietal lobe, occipital lobe, and frontal lobe.
Cortex has six layers of different types of neurons which are responsible for higher information processing and thinking. Cerebral cortex controls general movement, behavioural reactions, perception and visceral functions. We term the grooved layer as the brain itself.Cerebral cortex consists of large amounts of sulci and gyri(sulcus and gyri in singular). The number of gyri correlates to the processing ability of the animal.A man has big gyri compared to a rat.
1 The Earth's Moon has considerably less mass than the Earth itself. Not only is the Moon smaller than the Earth but it is only about 60 percent as dense as Earth. Thus the gravitational attraction on the Moon is much less than it is here on Earth and a person weighs less on the Moon
2 The strength of the gravitational force between two objects depends on two factors mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled the force of gravity between the objects is doubled increases, the force of gravity decreases.
3 If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power).

Answer:
The toxic chemicals present in the soil can decrease soil fertility and therefore decrease in the soil yield. The contaminated soil is then used to produce fruits and vegetables, which lacks quality nutrients and may contain some poisonous substance to cause serious health problems in people consuming them.
Answer:
Because asthma is aninheirited trait most of the time. It makes it hard to breath when active and need air. It brings mucus in the lungs and cloggs most of the lungs. Making it hard to breath.
Explanation:
The biogeographic regions that are the most likely to have species that show convergent evolution are Nearctic and Palearctic.
<h3>What are Nearctic and Palearctic?</h3>
The Nearctic and Palearctic are two of the eight (8) biogeographic regions present on the Earth planet.
Palearctic represents (in turn) the most widely extended biogeographic region present on the Earth planet.
Biogeographic regions are specific areas consisting of particular biological (biotic components) features.
