Some flowers show incomplete dominance. If RR = white and R'R' = red, which phenotypic ratio would
be expected in the o spring of two pink flowers?
Answers
Answer:
1 red: 2 pink: 1 white
0 red: 4 pink: 0 white would be the phenotypic ratio expected in the o spring of two pink flowers. So, the correct option is (D).
What is Phenotypic ratio?Phenotypic ratio defined as the relative number of offspring expressing a particular trait or combination of traits, which can be determined by performing a test cross and the frequency of the trait or trait combinations being expressed depending on the genotype of the offspring can be identified.
Phenotypic ratio is expressed as the ratio of different phenotypes present in the progeny of a cross where the ratios are numerical comparisons. For example, if one has three mangoes and two oranges, the ratio of mangoes to oranges will be 3:2.
For above given information, if we cross RR which is white with R'R' which is red, we will get 4RR' offspring which are pink in color. then the ratio will be 0 red: 4 pink: 0 white.
Thus, 0 red: 4 pink: 0 white would be the phenotypic ratio expected in the o spring of two pink flowers. So, the correct option is (D).

How does this question represent the law of conservation of energy that energy cannot be created or destroyed? Consider the role of photosynthesis in your answer.
Answers
You need to put this into your own words, or else your school system will detect you copied from a source named Brainly.
Anyways, the law of conservation of energy is exactly what it says. Energy cannot be created nor destroyed. All they do is rearrange.
Now, for photosynthesis, it's an interesting thing. Photosynthesis takes the energy from the sun's light to produce sugars/carbohydrates. The sun's energy just got reused. It also uses water, which comes from the soil/ground. This simply, reuses the water. During photosynthesis, it also absorbs the carbon dioxide from the air. The carbon dioxide like everything else listed, got reused.
Meaning, energy does not leave. It endlessly works for different purposes. And as you should know, all of the water on the planet has been here since the dawn of time.
Hopefully this makes sense. Have a nice day!

Explanation:
Each organ is made up of several different types of tissue. Therefore, for every organ in the body, there are many more tissues.
Answer: Venn diagram of exocytosis , diffusion , endocytosis , osmosis is
described below.
Explanation:
Exocytosis: refers to the process by which the contents of a cell are released to the exterior environment through fusion of the vacuole membrane with the cell membrane.
Endocytosis: refers to the process in which cells take the material from outside the cell by taking in the vesicle. These materials serve as nutrients and pathogens which help cell to fight against foreign diseases.
The common thing these two process have among them is
FlagellaPlasma MembraneCell divisionCytoplasmRibosomes chromosomesDiffusion: It is the process of movement of molecules from through a
semipermeable membrane from the region of higher concentration to lower concentration.
Osmosis: The movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's fractionally permeable membrane.
The common thing these two process have among them is that equalizes the concentration of two solutions in mixture

Enzymes are most effective at a particular pH and temperature but can function over a range of pH and temperature.
B
С
Enzymes do not have a specific pH or temperature at which they are most effective but function optimally over a range of pH and temperature.
Enzymes work equally well at the low and high ends of their temperature range but reaction rate drops quickly at the high end of their pH range
Enzymes only function at a specific pH and temperature and cannot function over a range of pH or temperature.

Enzymes are the bio-catalysts. Their presence can increase the rate of a reaction. Enzymes are most effective at a particular pH and temperature but can also function over a range of pH and temperature. Thus, correct option is A.
What are Enzymes?Enzymes are the biocatalysts which are responsible for increasing the rate of a chemical reaction. The enzymes increase the rate of a reaction by decreasing the activation energy which is required by the reactant molecules to collide and form products.
Enzymes are found to function over a range of pH, temperature, and solvents. Enzymes work over a range of different conditions. The value of pH and temperature at which enzymes show highest activity is called optimum condition. Below and above this point, enzymes function but the activity will be lesser than that in the optimum condition.
Therefore, A is the correct option. Enzymes are most effective at optimum condition of pH and temperature.
