In Smileys, eye shape can be starred (SS), circular (CC), or a circle with a star (CS).
On paper, do a Punnet square with a cross between a star-eyed and a circle eyed.
What are the phenotypes of the offspring? What are the genotypes of the offspring?
Your answer:
Answers
The phenotypes of the offspring would be a circle with a star eye shape and their genotype would be CS
Star-eye is SS and circular eye is CC.
SS x CC
CS CS CS CS
All of the offspring will have CS as genotypes. Since the CS genotype codes for a circle with a star eye shape, it means that all the offspring will also have a circle with a star eye shape.
You can find attached the Punnet square analysis of the cross.

1. All living organisms are composed of one or more cells
2. The cell is the basic unit of structure and organization in organisms
3. Cells arise from pre-existing cells
*C. is not one of them*
D. All cells have all the same structural parts is NOT a tenet of the cell theory.
The Cell Theory gives a description of what cells are. There are basically some set of principles that give a concise idea of what cells are. These set of principles are regarded as tenets of the cell theory.
Three major scientists named: Rudolf Virchow, Theodor Schwann, and Matthias Jakob Schleiden are credited to have postulated the tenets of the cell theory.
The major tents of the cell theory include the following:Every living thing on earth are composed of cellsThe functional and structural unit of all living things are cellsThrough the process of division, new cells are formed from old cellsThe chemical composition of all cells are the sameNote: All cells however do not have the same structural parts.
Therefore, option D. All cells have all the same structural parts, is NOT a tenet of the cell theory.

D. Nucleus
Answers
A stretch of DNA with instructions for one trait is called as Genes. So, the correct option is (B).
What are Genes?Genes are the basic units of heredity passed from parent to child that are made up of sequences of DNA and arranged one after another at specific locations on chromosomes in the nucleus of cells.
A gene is described as the basic physical and functional unit of heredity that is made up of DNA. Some genes serve as instructions for making molecules called proteins, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to over 2 million bases.
Genes carry the hereditary information from one generation to the next which control the structure and metabolism of the body.
Thus, a stretch of DNA with instructions for one trait is called as Genes. So, the correct option is (B).

Answers
Answer:
this is the answer from edmentum
Explanation:
The main reason that people eat is to get energy and the energy is used by the body to carry out its daily activities.
It should be noted that when we eat, the food needs to be broken down in order for the body to use them. This is done through the process of cellular respiration.
The energy that is in the food that's consumed by human beings is changed into the energy that's usable by the body cells. For example, the sugars in the foods will be digested into a monosaccharide. Also, the energy that's stored in the glucose is converted to ATP which is vital for the body.

Answers
Living organisms can incorporate nitrates into their metabolism.
Nitrates are compounds that we can find in nature, originated in the nitrogen cycle.
Plants can obtain nitrogen in the form of nitrate (NO3-) and ammonium (NH4 +).Nitrates are absorbed and accumulated by plants, being transmitted to humans through the consumption of vegetables and water.These compounds, in turn, serve as food for other types of prokaryotes, this time denitrifying metabolism, that is, they decompose nitrite and nitrate ions, and obtain energy to live.Therefore, we can conclude that the nitrate ion (NO3–) forms some of the presentations usable by animals and plants.
