Good afternoon. An organelle is any structure in cells that has a specialized function. They are usually found in eukaryotic (nucleus) cells. They help with energy, making proteins, and removing wastes from a certain area. They are composed of large molecules such as proteins, carbohydrates, lipids, and nucleic acids. I hope I helped!! If you have any more questions then don't hesitate to let me know. Have a great day!!
Answer: a hard sedimentary rock, composed mainly of calcium carbonate or dolomite, used as building material and in the making of cement.
Answer: photosynthesis
Explanation: In photosynthesis, carbon dioxide and water reacts in the presence of sunlight to produce glucose and oxygen. In photosynthesis, oxygen is released in to the atmosphere while the glucose formed is stored in the plant as food. No carbon is introduced in to the atmosphere during respiration rather carbon dioxide is used up.
In respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide, water and energy. Carbon is introduced in to the atmosphere in form of carbon dioxide.
In forest fires and burning of fossil fuels, wood and fuels burn in sufficient supply of oxygen liberates carbon dioxide (CO2) but when it burns in insufficient supply of oxygen, it liberates carbon monoxide (CO). In both cases carbon is introduced in to the atmosphere in form of carbon dioxide or carbon monoxide.
Answer:
120 white individuals
30 yellow individuals
10 green individuals
Explanation:
Available data:
- Dominant epistasis: Phenotypic frequencies 12:3:1
- W allele codes for a dominant white phenotype
- w allele codes for a colored squash
- Y allele codes for a dominant yellow phenotype
- y allele codes for a recessive green phenotype
- W allele will always mask the phenotype produced by Y or y alleles

F1 Phenotypic Frequency)
White phenotype: 12/16 = 120 individuals
Yellow phenotype: 3/16 = 30 individuals
Green Phenotype: 1/16 = 10 individuals
To know how many offspring are expected to have the white, yellow, and green phenotypes, you can perform a three simple rule. This is:
16 ------- 160 offspring
12 White ------- X = 120 offspring
3 Yellow ------- X= 30 offspring
1 Green --------X = 10 offspring
