Answer:
A pyramid of numbers gives a count of the numbers of individual organisms at each trophic level in an ecosystem.
Explanation:
This type of pyramid gives a good picture of the large numbers of producers that are required to support just a few top-level consumers.
The correct answer is “a dominant-recessive pattern".
A dominant-recessive pattern pertains to the characteristics of the allele to portray a certain phenotype. A dominant allele (represented by capital letters) will show the phenotype even if the other allele is recessive (represented by small letters). A recessive allele will only manifest a phenotype of both alleles are recessive.
For example:
A is the dominant trait that will make the peas green; a is the recessive allele that will make the peas yellow
The pair AA are both dominant alleles and will make the peas green. The pair Aa has both the dominant allele and the recessive allele but since the dominant allele is present, the peas will still be green. The pair aa has both the recessive allele and will make the peas yellow.
- Matter is organic if it has carbon atoms present in it.
- The two tests include photosynthetic and postembryonic tests.
- The phenotypes include the following:
<h3>What is Phenotype?</h3>
This refers to the physical and observable characteristics of an organism.
- The genotype for having a white fur is an example in this scenario.
- The defining characteristics of each kind of tissue is based on their components and functions.
- The skull has bones, blood vessels and nerves which would fit each tissue type.
- The enzyme pepsin is produced in the stomach.
- Testosterone is a hormone produced in the male reproductive system.
- Oil doesn't have any polar part and so for them to dissolve in water resulting in them floating.
The three common substances which are examples of lipids include:

Answer:
A theory is an explanation that why something occurs while the hypothesis is a prediction or guess about what will happen.
A theory is a conclusion that is given after many experiments while a hypothesis is an idea that is given before an experiment that what will happen as a result experiment.
The periodic theory explains that elements would repeat their properties repeatedly. The theory also made a hypothesis that certain elements would be discovered.
