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:
The given first statement is true, that is, with the increase in the demand for chicken, the chicken market will rise, and in the same way with the decline in the demand for beef, the production of cattle will decrease based on the law of demand.
The given second statement is also true, as the resources mentioned in the given statement is a tragedy of commons as the common access resources are rivalrous and non-excludable.
The given third statement is also true, as the mentioned ocean fisheries is a tragedy of commons as the common access resources are rivalrous and non-excludable.
Answer:it described how carbon is recycled between earth's biosphere, hydrosphere, geosphere and atmosphere. Carbon is an essential element for all life forms so understanding how it is recycled will help us to understand factors and all the biological processes that influence them.
Explanation:
Answer: alternative A.
Explanation: Fixism was a current theory during biology history, and it stated that species were always like they are at the present time, not being able to change during time. Darwin's evolutionary theory, developed at the 19th century, said the opposite: species were able to change and they still do it. One way to prove it was <u>studying fossils and its morfologycal characteristics in order to link them to more recent species</u>, and <u>establish a taxonomical connection between them</u>. The study of fossils is know as paleontology, and it this way it changed the naturalist's views.
