Think about a petal plucked from its flower. When the petal is removed from the flower, will it remain alive according to
schepotkina [342]

When a petal is plucked from a flower, it will not remain alive for very long. It will soon start to decompose.

Explanation:

To understand this, we need to go back to the act of plucking the flower as such from the plant. The moment a flower is plucked from a plant, it stops receiving any further nutrition from the plant. Whatever nutrients were present in the flower at the time of plucking it will continue to keep it alive and once those nutrients are used up, the flower will start to decompose.

In this case, since the petal is plucked from a flower which already was surviving on limited nutrients, it will decompose very quickly.

According to the characteristics of life, it cannot be considered dead at the time it's plucked. It <u>continues to live, but for a very brief time</u>.

Explain how the process of meiosis relates to the way in which a child
prisoha [69]
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. That means that they will never be a copy of their parents because of their different genetic material. Characteristics, such as eye color, hair type and color, the shapes of facial features, and height and build, and attribute the combinations of these to the portions of DNA inherited from each parent which makes them different but still carry the DNA of their parents.

Explain why the sequence of dna bases is just like a sequence
Westkost [7]

DNA is nothing more than a sequence of bases (nucleotides) and since DNA is normally double stranded, they can be referred to as base pairs. One could best visualise it like a zipper: two connected strands (that can also be separated). DNA is made up of only four different bases, abbreviated as A, C, G and T. These always form the same pairs: A on one side of the zipper, T on the other side and the same goes for C and G. So, when unzipped, you always know the sequence of the opposite strand.

The sequence of base pairs that make up our DNA should be viewed like a bar code. Every set of three bases code for one building block of a protein. That's all that DNA is for: code for building proteins. A set of three bases is called a codon and tells machinery in the cell (ribosome) to add one specific building block to a forming protein. It's like Lego and DNA is the instructions that tell you which block to add next.

These different blocks give shape and function to the proteins it helps to build.
