In pea plants, yellow seed color is dominant and green seed color is recessive. what will the generations look like? assume that mendel’s method of crossing two true breeding parents with opposite traits is followed. check all that apply. the p generation has all yellow seeds. the p generation has all green seeds. the p generation has yellow and green seeds. the f1 generation has yellow and green seeds. the f1 generation has all yellow seeds. the f2 generation has all green seeds. the f2 generation has yellow and green seeds.

The correct statements are:

The given cross is the monohybrid cross between the plant with yellow seeds and plant with green seed.

Thus, the parent generation contains both yellow and green seed plants.

Let Y and y  be the alleles of the gene responsible for seed color. Y is the dominant trait which codes for yellow color and y is the recessive allele which codes for green color.

The genotype of one parent is YY and that of another would be yy.

The cross would produce the offspring with genotype Yy. Thus, all the offspring would have yellow color seeds as yellow is the dominant trait.

On selfing F₁ generation, the offspring would produce with three types of genotypes YY, Yy, and yy in the ratio 1:2:1.

Thus, F₂ generation would contain yellow and green seeds in 3:1.

allowed for the prediction of the properties of missing elements.

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#4

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.
