<span>A stem is one of two main structural axes of a vascular plant, the other being the root. The stem is normally divided into nodes and internodes. The nodes hold buds which grow into one or more leaves, conifer cones, roots, other stems, or flowers (inflorescences); the internodes distance one node from another.</span>
Answer:
The natural selection is a theory made by Charles Darwin where animals better adapted to their environment tend to survive and produce offspring. for example, there are about 50% of beetle that are green and 50% orange. If crows tend to eat green beetles more, there will be more orange beetle to produce offspring so there wood then be less green beetles to be eaten by crows.
An environment can change over time and this will cause for the animals living in the environment to adapt as well. These changes will occur when an animal with undesirable traits don't survive to reproduce. The offspring of individuals that do survive to reproduce will inherit their parent's desirable traits. Over many generations, the desirable traits will be seen in more-and sometimes all- of the individuals in the population
Explanation:
That is the natural selection told in my words, but please do your best to rewrite your own sentence/paragraph. Copying another's work is called plagiarism and any teacher can automatically give you a 0% for this.
Anyway, goodluck.

The given question is incomplete as the genotype of the parents is not given, so the answer is providing in the followings case:
1. dominant parent and recessive parent
2. heterozygous parents
Answer:
1. dominant parent and recessive parent:
dominant parents can be represented by LL and recessive parent is represented by ll, so the gametes would be L, L and l, l.
so,
L L
l Ll Ll
l Ll Ll
so there are all offspring in heterozygous condition as we known one or two dominant allele masks the recessive allele for the trait so 100% offspring can fold their tongue.
2. heterozygous parents
In this case, parents have Ll genotype and gametes would be L and l for each parent so,
L l
L LL Ll
l Ll ll
In this case, one is pure dominant and two heterozygous whereas only one is recessive so, the phenotype of offspring that cant fol the tongue would be:
3/4 = 75%
If it is more salty it means that the water is hypertonic to the hypotonic potato and if the water is less salty then the water is hypotonic to the hypertonic potato
