The answer is B. the superior competitor. Hope this helped brainliest:))
The null hypothesis is: there is no significant effect negative effect of increasing caffeine concentrations in nectar on the number of floral visits by bees.
If the number of floral visits by bees decreased with increasing nectar caffeine concentration, the null hypothesis is rejected. If there were no significant changes, the null hypothesis is not rejected.
<h3>What is a null hypothesis?</h3>
A null hypothesis a hypothesis which states that there is no significant difference between two populations or sample under study.
A null hypothesis can also state that there is no significant difference between variables in a study.
The experiment is to test potential negative effects of increasing caffeine concentrations in nectar on the number of floral visits by bees.
The null hypothesis is that there is no significant effect negative effect of increasing caffeine concentrations in nectar on the number of floral visits by bees.
The experiment will be designed as follows:
- Four potted plants with normal nectar caffeine concentration (serving as control), x2 nectar caffeine concentration, x3 nectar caffeine concentration, and x5 nectar caffeine concentration are obtained and kept in a garden.
- The number of floral visits by bees are recorded after 15 days.
If the number of floral visits by bees decreased with increasing nectar caffeine concentration, the null hypothesis is rejected. However, if there were no significant changes, the null hypothesis is not rejected.
In conclusion, a null hypothesis is a hypothesis of no significant difference.

Answer:
QUESTION NUMBER THREE DONEE YA BOIIIIIIIIII
Explanation:
Answer: composed of building blocks called nucleotides.
<span>Nucleic acids are small but not simple
molecules. They are the most important biomolecules because of their several
functions. They are composed of building blocks called nucleotides but not a source
of cellular energy. </span>
Answer:
Gene- DNA - Chromosome- Nucleus
Explanation:
A gene is a sequence of nucleotide bases that specifies certain products; RNA or proteins. It is the segment of DNA that holds the information to build and maintain an organisms cell and also pass genetic traits to offsprings. Hence, it is the molecular unit of heredity in living organisms.
The DNA is a long double-helical structure that stores the genetic information in our cells. It consists of two long polynucleotide chains composed of the four nucleotides subunits (A,C,G,T).
In order for the long strand of DNA to fit into the cell's nucleus, it is coiled around certain proteins called HISTONES to form Chromatin, which undergoes further coiling and organization to to linear CHROMOSOMES.
The chromosomes are structured within the nucleus, that are made up of the cell's genetic material (DNA). In eukaryotic cells, the nucleus houses the cell's DNA and directs protein synthesis (expression of the information encoded by genes).
