Please explain the solution of this?
Question 14: Attempted
A cell divides every minute.It will fill a 100ml beaker in hour.How much time would it take to fill 50 ml beaker.

58 minutes
15 minutes
30 minutes
59 minutes

If a cell divide every minute, the number of cells get doubled at the end of each minute.If a 100 ml beaker is filled in one hour, it will take 59 minute to fill 50 ml beaker.

Meiosis cell division consists of two phases. First phase is called meiosis I during which number of chromosome reduce to half. In meiosis II chromosome number remain same.

Subject: Biology, asked on 13/3/17

what is interkinesis?
Question 15: Attempted
The stage connecting meiosis I and meiosis II is

Interkinesis
Interphase II
Anaphase I
Interphase I

Interkinesis is the stage connecting meiosis I and meiosis II cell division.It is a brief period between two stages.No DNA synthesis occurs during this period.

I had read somewhere that Genes control the cell divsion, that's why clicked that option, why I was incorrect? please telWhat to do when both genetic make up and hormones are option to choose?
Question 7: Attempted
Plant mitosis is generally controlled by

Genetic make-up
Cytochrome
Auxin
Cytokinin

In plant cell,mitosis cell division is generally controlled by cytokinin hormone.Auxinins also required for cell division in plant.

Why the option in red colour is incorreect?
Astral body are formed of

Microfilaments
Microvilli
Microtubules
Intermediate filaments

Astral body are formed of microtubules.Astral bodies are produced by centriole during cell division and attach with centromere of the chromosome.

Why the option in red colour is not correct?
Question 1:Attempted
Cell growth results in disturbing the ratio between

Cytoplasm-spindle fibre ratio
Cytoplasm-chromosome ratio
Nucleus-chromosome ratio
Nucleus-cytoplasm ratio

Cell growth results in disturbing the ratio between the nucleus and the cytoplasm.It therefore becomes essential for the cell to divide to restore the nucleo-cytoplasmic ratio.

Please tell whethere the answer in green colour is correct or not? because according to me it is not correct.
Question 15:Attempted
In which stage of mitosis,the number and shape of chromosome can be observed?

Metaphase
Prophase
Anaphase
Telophase

The metaphase is characterised by all the chromosomes coming to lie at the equator with one chromatid of each chromosome connected by its kinetochore to spindle fibres from the opposite pole.

Subject: Biology, asked on 13/3/17

Please tell whethere the answer in green colour is correct or not? because according to me it is not correct.
Question:11 Attempted
S phase marks

Cytoplasmic growth
It carries out normal metabolism
Chromosome condensation
DNA replication and chromosome duplication

S phase marks the phase of DNA replication and chromosome duplication.

What is the highlighted word?

Subject: Biology, asked on 13/3/17

Are sister chromatids also known as daughter chromatids

Subject: Biology, asked on 13/3/17

What are the difference between centromere and kinetochores, because both are sounding same to me? I have read both are the point at which sister chromatids are attached indeed kinetochore is a protein.

Subject: Biology, asked on 13/3/17


If sister chromatids are shown by arrow in the pic, then what will we call to the structure which is in blue coloured box?

Subject: Biology, asked on 13/3/17

Can we say that sister chromatids are two arms of a chromosome attached at centromere?

Subject: Biology, asked on 13/3/17
