Answer:
The substance moves from low to high concentration, against the concentration gradient.
Explanation:
When molecules move from high to low concentration, it is known as Diffusion. It moves with the concentration gradient and does not require energy.
However, when molecules move from low to high concentration, it is against the concentration gradient and cannot proceed without Energy. This process is called Active transport.
Cell membrane is not thick, it is thin and semi permeable.
PCR technique is important in STR profiling in order to amplify and detect the number of Stars at a specific gene loci.
<h3>What is Short Tandem Repeat (STR) profiling?</h3>
Short Tandem Repeat profiling is a technique in molecular biology used to compare allele repeats known as STRs at specific loci in DNA between two or more samples.
The PCR (polymerase chain reaction) technique used in STR profiling involves making multiple copies is a particular segment of DNA in order to make enough quantities detectable in the analysis.
Therefore, PCR technique is important in STR profiling to detect the number of Stars at a specific gene loci.

In meiosis, the chromosome pairs do the crossing over where there is an exchange of genetic material between them and because of it the
chromatids held together by the centromere are no longer the same.

Answer:
Both flowers and runners help a plant to reproduce.
Explanation:
Both flowers and runners help a plant to reproduce. While a flower help in sexual reproduction, a runner helps in asexual reproduction.
A flower has both male and female gamete at one place. When the pollen grains with in a flower reaches the female ovary, a new seed is produced which has the potential to develop into new plant. In case of runner (which is a stem), the tip of the stem has the potential to grow into a new plant
