Hi

Yes, in NEET examination Biology is of 360 marks, physics is of 180 marks and chemistry is of 180 marks as well.

And,

No, there is no sectional cutoff in NEET examination means there is no minimum marks requirements separately in each of physics chemistry and Biology, there is only overall cutoff which you need to quickly clear.

For example,

Let's say you attempt only Biology questions and you get all the 90 questions correct then your marks will be 360marks , but you didn't attempt Physics and Chemistry questions and get 0 and in Physics and Chemistry but in that case also you will be able to clear your Neet examination with 360 marks in Biology as there is no minimum requirement of marks in Physics and Chemistry.

last 3 years qualifying cut off data is given below for reference :-

.                 .  Year wise cut off marks

Category     2020             2019          2018

General   720-147        701-134      691-119

UR-PH     146-129         133-120      118-107

Obc/sc/st  146-113     133-107       118 - 96

From, above you can see there there is only overall cutoff there is no sectional cutoff

To be on the safer side you should try to get at least 15 to 20 marks more  in comparison of Neet 2020 cut off as per your category i. e if you belong to general category then try to get atleast around 160 marks in order to qualify Neet 2021.

But yes,
Just qualifying with Neet cutoff won't help you to fetch a seat in a Government Medical College so you should try to get at least around 575 marks if you belong to general category.

Now , limited time is left for your neet 2021 examination, so focus on preparation, go through the chapters , practise questions and then revise them, go through mock test papers once you are done with complete syllabus.
