CF is a recessive type of disorder which means that both parents must carry the gene in order for the child to inherit the disease. If the child only inherits 1 copy of the affected gene, then the child becomes a carrier. Carriers do not manifests symptoms of the disease but they can pass the disease to their children.
With both parents as carriers, they will have the following chances: 50% carrier children, 25% affected child, and 25% normal child.
Answer:
I think the answer is a plant cell contains one large vacuole in its wrong because they have a nucleus I did not all plants have the same size or shape and they only have one large vacuole or sap vacoule hope it helps
Plants and animals could not live without nitrogen. It is an important part of many cells and processes such as amino acids, proteins, and even our DNA. It is also needed to make chlorophyll in plants, which plants use in photosynthesis to make their food and energy.
Nitrogen is an important component of many essential structural, genetic and metabolic compounds in plant cells. It is also an elementary constituent of numerous important organic compounds including amino acids, proteins, nucleic acids, enzymes, and the chlorophyll molecule.
Of all the essential nutrients, nitrogen is the one that is most often limiting for crop growth. Nitrogen is the nutrient which normally produces the greatest yield response in crop plants, promoting rapid vegetative growth and giving the plant a healthy green color.
Answer:Plate tectonics explains why Earth's continents are moving; the theory of continental drift did not provide an explanation. Therefore, the theory of plate tectonics is more complete. It has gained widespread acceptance among scientists
Explanation:
Answer is A. A population becomes separated by environmental factors into two groups that do not reproduce with one another.
When a population of a species become geographically separated then gene flow between them stops. Over a period of time, the population may become genetically different in response to the natural selection due to different environments. Selection and genetic drift will act differently on these two separated populations. This will results into two separate species. This type of speciation is called allopatric speciation.
