The cerebral cortex process the information delivered by the thalamus, the information is related to the senses.

The only system that does not pass through the thalamus on its way to the cerebral cortex is the olfactory system.

The systems that pass through the thalamus are:

1. The visual sensation or information passes through the visual occipital cortex. It then delivers the information from the thalamus to the cerebral cortex.

2. The gustatory cortex is the region of the cerebral cortex, which is responsible for the senses of tastes and flavor. It also passes through the thalamus on its way to the cerebral cortex.

3. The tactile system includes the senses of touch. It is the information received through the receptors present on the skin. It also delivers the information to the cerebral cortex via the thalamus.

4. The olfaction system is not involved in the thalamus pathway. The olfactory cortex is present in the temporal lobe, which is not routed through the thalamus.

brief summary of conservation of forests & wildlife

least 10 page

Answers

With the advent of industrialization, several trees have been cut at an alarming rate for raw materials and various other purposes. This felling of trees can be regulated by selective cutting, clear-cutting and shelterwood cutting.

Forest fires are one of the common causes of loss of forests. Sometimes the forest land is set on fire to make the land available for commercial purposes. Once cleared, there can be no vegetation. Natural forest fires are also responsible for the destruction of huge forest covers. Latest fire fighting techniques should be adopted to conserve the forest. However, forest fires are an important part of the ecosystem and it helps replenish nutrients in the soil from dead and decaying matter.

More trees should be planted to increase the forest cover. Trees should be selected according to the geographical conditions of a particular region and proper care should be taken during the growth of trees.

Prevention of exploitation of forestry and forest products is necessary for the conservation of forest.

The existing forests should be protected from diseases by spraying chemicals, antibiotics or development of pest-resistant strains of trees.

Which statement is true about the law of reflection?
The angle of reflected light is the same as the incoming angle of light.
The angle of reflected light distorts the image to appear larger or smaller.
The angle of reflected light is smaller than the incoming angle of light.
The angle of reflected light is larger than the incoming angle of light

Answers

Answer:

The law of reflection defines that upon reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray, with respect to the normal to the surface that is to a line perpendicular to the surface at the point of contact.

The reflected ray is always in the plane defined by the incident ray and the normal to the surface at the point of contact of the incident ray.

The images produced by plane mirrors and curved mirrors can be understood by the law of reflection.

Law of reflection is defined as:

The principle when the light rays falls on the smooth surface, the angle of reflection is equal to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in the same plane.

What is Reflection of Light?

The process through which light rays fall on the surface and gets bounced back is known as a reflection of light.

Explanation:

Answer: The angle of reflected light is the same as the incoming angle of light.

O C. 1 grasshopper/1 square meter
O D. 50 grasshoppers/30 square meters

Answers

35 grasshoppers/10 square meters has the highest population density.

The highest population density of grasshoppers is 35 grasshoppers/10 square meters because more number of organisms are present in less area as compared to other population density. In the option i.e. 40 grasshoppers/20 square meters and 50 grasshoppers/30 square meters have more number of organisms but the area is also greater.And we know that high population density means more number of organisms in less area so we can conclude that 35 grasshoppers/10 square meters has the highest population density.
