Initiating force of evolution is :- 1. Variation. 2. Natural selection. 3. Adaptation. 4. Compition.

Somrita Bhattacharya 12th Jan, 2020

The correct answer is Variation.


Explanation:

The various traits or behaviours of an organisms are seen to have evolved over many years through natural selection, with the main aim of surviving in the environment. Natural variation is the process in which individuals are better adapted in the environment, with the main aim of surviving and reproducing. Variations, often down the genetic level, or caused by genetic mutation, often allows some members of a species to be better adapted to an environment. This also helps in the process of evolution, thus initiating natural selection and initiating force of natural selection.

Hope it helps

IF I SCORE 480 IN NEET 2019 THEN WHAT WILL BE THE FEE FOR MBBS IN THESE COLLEGE AND HOW MUCH SCOLORSHIP DID I GET PLEASE GIVE ME AN EXACT VALUE

priyaankasarkar Student Expert 10th Jan, 2020

Hari, you haven't mentioned the College you are enquiring about. Neverthless, your fees largely depends on the score and College you get placed in. All the Government Medical Colleges of a particular State will have the same fees. And Private Medical Colleges have 3 Categories.  The first is Govt. Quota, the next is Management Quota and the 3rd is NRI Quota. Now the scholarships are subjective to the State you belong to and its scholarship programmes. Few Colleges do have merit based and need based scholarships. But it is again State to State basis. No scholarship is given based on your NEET marks on a general note.

if all regulate gets advantage over conform then why comforms did not comvert int regulate wirh evolution .

Khushi 25th Dec, 2019

HELLO!!

Thermoregulation is energetically expensive for many organisms,specially for small animals like birds,shrews.we know that heat gain or heat loss is the function of surface area.Since these small animals have larger surface as compares to there volume they lose body heat very fast during  exposure to cold environment.To maintain their metabolism they have to expend much energy to keep their body warmer that much energy a small creature could not afford and thus they simply conform.

THANK YOU!!

how is it important to understand about evolution in medical field?

Khushi 26th Jan, 2020

Hello!!

Knowing the evolutionary relationships among species allows scientists to choose appropriate organisms for the study of diseases, such as HIV. Scientists are even using the principles of natural selection to identify new drugs for detecting and treating diseases such as cancer.
