I think the thalamus is the gateway to the cerebral cortex. Thalamus is a small structure within the brain located just above the brain stem between the cerebral cortex and the mid brain and has extensive nerve connections to both. Its main function is to relay motor and sensory signals to the cerebral cortex. A sensory impulse travels from the body surface towards the thalamus, which receives it as a sensation, which is then passed onto the cerebral cortex for interpretation as touch, pain or temperature.
Answer:
Virchow was a German scientist whose most important work was in the filed of cellular biology and pathology.His scientific experiments and examinations aimed to disprove the idea of spontaneous generation. This idea is based on an assumption that life can spontaneously appear out of non-living matter. After years of scientific work he concluded that only living cells can produce other cells, or that only life can produce life.Therefore, if it was somehow proven that cells can be generated from non-living matter, that would disprove his findings.

Answer:
The photosynthetic rate refers to a determination of maximum rate at which leaves possess the tendency to fix carbon at the time of photosynthesis. The simple way by which the photosynthetic rate can be determined is by measuring the concentration of carbon dioxide produced.
It is known that the concentration of carbon dioxide, light intensity, and temperature are the three main elements, which affect photosynthesis. The enhanced concentration of carbon dioxide and higher light intensity results in higher photosynthetic rates.
In the given case where Elodea is used to study photosynthesis, it can be seen that at high light intensities, the concentration of bubbles increases as there is an elevation in the concentration of carbon dioxide.
The single celled protists which is one of the example of
this is the paramecia survives and lives on extreme hypotonic environment. They
have the ability of having to contract their vacuoles in which this contributes
and help them to live and survive in a hypotonic environment.
Answer:
<em>The correct option is C) The success of a species depends on the number of offspring that survive long enough to reproduce.</em>
Explanation:
Some species of animals such as the octopus might give rise to many offspring, but these offspring might not survive due to different reasons. Only a few of them will be able to survive until the age where they can reproduce.
On the other hand, the survival rate of offspring which are formed in lesser numbers is more. These offspring are taken care of by their parents usually or are better adapted to live in the environment. Hence, their survival rate is more.
