1) Interphase is the longest phase and most of the cells are present in that very stage !!
2) Interphase is the longest phase and Anaphase is the shortest phase !! Interphase is the longest phase as in this phase the cells prepare themselves for dividing and it takes most of the time for gathering energy for division ; in this phase DNA also replicate !!
3)
Interphase: DNA replicates;
Prophase: Nuclear membrane starts disappearing and Centrioles go on opposite poles !! DNA condense to form Chromosome.
Metaphase: Chromosome attach to spindle fibre and starts to move to equitorial plate.
Anaphase: Centromere divide and half the chromatid goes on either pole
Telophase: Nuclear membrane starts to reassemble; Chrmosome goes to normal uncoiled state ; Other organelles starts appearing
Cytokinesis: Cell furrow forms and cell divides into two half.
4) In dividing cell nucleus membrane is absent while in non dividing cell the membrane is intact
5) Tip of the onion root is meristamatic cell which divides but if it is permanent cell ; there would be no division !!
Answer:
a video that shows penguin species that have different mating dances
Explanation:
The question is incomplete as it does not have the options which are:
- a video that shows a large river that has penguin populations on both sides
- a video that shows penguin species that have different mating dances
- a video that shows a penguin that is laying eggs
- a video that shows penguins in a tidal pool and an open ocean
Answer:
a video that shows penguin species that have different mating dances
<em><u>The reproductive isolation is the factor which allows the species to evolve and form a new species, therefore, this factor is used to describe a species.</u></em>
<em><u /></em>
<em><u>The reproductive isolation refers to a mechanism in which the species are isolated to not interbreed with the individual of other species. The reproductive isolation could be due to behavioural, psychological, physical or genetic differences. evolved as an adaptation.</u></em>
<em><u /></em>
<em><u>In the given cases, the penguin species which shows different mating dances is considered to be reproductively isolated as the different dance rituals evolved as behaviour to prevent them from mating.</u></em>
<em><u /></em>
<em><u>Thus, the selected option is correct.</u></em>

Hey there!!
Your answer is epithelial tissue. This tissue is the one that does it part to protect all of the other cells around too or form the external barrier.
Hope this helps!!

Answer:
proteins, because it helps in the regulatory function of the body.
Answer:
0.0211 M concentration of pesticide will remain after 62.0 min.
Explanation:
Initial concentration of the pesticide = ![[A_o]=0.0314 M](https://tex.z-dn.net/?f=%5BA_o%5D%3D0.0314%20M)
Final concentration of the pesticide after t time = ![[A]=?](https://tex.z-dn.net/?f=%5BA%5D%3D%3F)
t = 62.0 minutes
Rate constant of the reaction = k = 
For the first order kinetics:
![[A]=[A]_o\times e^{-kt}](https://tex.z-dn.net/?f=%5BA%5D%3D%5BA%5D_o%5Ctimes%20e%5E%7B-kt%7D)
![[A]=0.0314 M\times e^{-6.40\times 10^{-3} min^{-1}\times 62.0 min}](https://tex.z-dn.net/?f=%5BA%5D%3D0.0314%20M%5Ctimes%20e%5E%7B-6.40%5Ctimes%2010%5E%7B-3%7D%20min%5E%7B-1%7D%5Ctimes%2062.0%20min%7D%20)
![[A]=0.0211 M](https://tex.z-dn.net/?f=%5BA%5D%3D0.0211%20M)
0.0211 M concentration of pesticide will remain after 62.0 min.
