This is showing possible outcomes, genotypes and phenotypes, of offspring from two parents. this is usually shown using a punnett square.
example: a monohybrid genetic cross is a genetic cross where only one gene or trait is being studied: a cross between a tall plant and a short plant. it could be represented as tt x tt. in this case, the genetic cross would produce tt offspring that are all tall.

A homozygous short (tt) plant is crossed with a heterozygous tall (Yy) plant. The phenotypic ratio of the offspring is 50 percent Tt and 50 percent tt.

Further Explanation:

Genotypes help in the genetic makeup of any individual. Phenotype describes as a physical characteristic of an individual. The genotype is responsible for the phenotypes of any individual. If two copies of the same alleles present in an organism, its genotype is called homozygous. If two copies of different alleles present in an organism, its genotype is called heterozygous.

When a homozygous dominant individual is crossed with the homozygous recessive individual, the resultant offspring has the genotype, which is heterozygous and phenotype, which is dominant. All possible genotypes of the parent, as well as offspring, are graphically represented in a Punnett square.

In the given punnet square below, the parent homozygous green plant having a genotype tt is crossed with the parent heterozygous yellow plant having a genotype of Tt. The resultant offspring of filial generation tends to be 50 percent of Tt, which means heterozygous and 50 percent tt, which means homozygous.

question#1

ans:

cell is the basic unit of organization of all living things. cells are often called the building block of life and it is the smallest unit of life. the study of cell is called cell biology. cell consists of cytoplasm enclosed within membrane, which contain bio-molecules such as proteins and nucleic acid.

two third of cell is water, which means that two-third of your whole body is water. the rest is the mixture of molecules, mainly proteins, lipids and carbohydrates.

question#2

ans:

organ:

an organ is a group of tissues specialized to form a functional unit. an example is the heart in animals.

organ system:

an organ system is a group of several organs whose functions are synchronized to release an effective action in a living organism. an example is digestive system.

question#3

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#5

our body works because of the interactions that happen between organs and organ systems.  

for example:  

the heart to regulate blood flow throughout the body. the blood carries oxygen and nutrients to the cells and carries carbon dioxide and waste away from the cells. body systems work together in maintaining a constant internal environment. when this balance is disrupted, the body systems may not function properly, and human health can suffer.   you start to feel bad.
