Alexander l.oparin I looked it up !
The whole thing, scientifically, fish are FOOD, not friends because a shark has to and fish is food for the shark... so the whole thing s scientifically incorrect
Answer:
The spindle fibre is necessary to separate the sister chromatids into opposite sides of the cell.
Please find detailed explanation below
Explanation:
Mitosis is the cell division that produces two daughter cells that are genetically identical to the parent cell. Mitosis occurs in stages viz: prophase, metaphase, anaphase and telophase. The replicated chromosome, aligns at the centre of the cell in the METAPHASE stage and separates into opposite poles in the ANAPHASE stage.
This alignment (at the equator) and separation into opposite pole is possible with the aid of a structure called SPINDLE FIBRES. Spindle is a structure formed from microtubules, which attach to the kinetochores (located in the centromere) of each replicated chromosome to separate them from one another. Hence, the purpose of the spindle fibre during mitotic division is to separate the GENETIC MATERIAL of a parent cell into two daughter cells.
Answer:
The correct answer is 150 minutes.
Explanation:
On the basis of the Physical Activity Guidelines, the majority of healthy adults should perform at least 150 minutes of moderately intense physical activity in a week in order to remain in a healthy state. Though more amount of aerobic activity would offer even more benefits, however, even a short amount of aerobic activities can also reap healthy rewards.
The moderate form of aerobic activities comprise activities like mowing lawn, brisk walking, and swimming. This form of physical activity is suggested for all the individuals coming under the age group 18-60 years, unless and until a person is suffering from any kind of specific medical conditions. It is recommended for all the adults irrespective of race and gender.
Answer:
Replicating DNA is fragile, and can break during the duplication process. In fact, broken chromosomes are often the source of DNA rearrangements and can change the genetic program of a cell. These changes can trigger a growth advantage in a single cell in your body, and when that cell continues to divide, tumors arise. Fortunately, our cells have defense mechanisms to shield us from these damaging events.
