The pedigree below shows several generations of a family in which cystic fibrosis runs. A healthy phenotype is dominant (C), and cystic fibrosis is recessive (c). Shaded individuals have cystic fibrosis. Symbols with question marks have unknown genotypes and phenotypes. 11. Individual 4 was found to have a genotype of Cc, which means individual 4’s phenotype is
A. healthy male
B. male with cystic fibrosis
C. healthy female
D. female with cystic fibrosis
The answer is B, right?
Answers
Answer:
The correct answer should be A
Explanation
Since we know the genotype of individual 4 to be Cc (heterozygous), and C indicates a healthy person. In contrast, c indicates having cystic fibrosis. We can conclude that this person is healthy. C is dominant over c; therefore, this person does not have cystic fibrosis. If this person did have cystic fibrosis, they would need to be homozygous recessive (cc). This does mean, however, that since the person has the recessive allele (c) for cystic fibrosis, they are a carrier of it. That means that if they were to have children with someone who had cystic fibrosis (cc) or was a carrier of the recessive allele (Cc), their children could possibly have cystic fibrosis.

Numerous defense systems exist in cells to stop mutations, or long-lasting alterations in DNA sequence.
Numerous defense systems exist in cells to stop mutations, or long-lasting alterations in DNA sequence. Most DNA polymerases "check their work" during DNA synthesis, correcting the majority of mis paired bases in a procedure known as proofreading. Any mismatched bases that are still present after DNA synthesis can be found and fixed through a procedure known as mismatch repair.
Different processes, such as chemical reversal, excision repair, and double-strand break repair, can be used to fix damaged DNA.
In fact, replication mistakes and DNA damage occur often in the cells of our bodies. However, they typically don't result in cancer or even mutations. That's because DNA repair and proofreading systems typically identify them and fix them. The cell will also go through programmed cell death (apoptosis), which prevents the flawed DNA from being passed on, if the damage cannot be repaired.

make a claim that answers the scientific questions, how effective is Kernza at reducing the amount of nitrate in the soil water? And, is it equally effective over time
Answers
The reduction of the amount of nitrate in soil water proposed by Kernza is very effective, because nitrate dissolves well in water. This one helps to facilitate the use of the plants, but can also end up in rivers and groundwater.
Underground water with only 10 milligrams of nitrate per liter is not safe drinking because it can lead to greater risk of cancer and birth defects. That is very expensive to remove nitrate from drinking water. Cities whose groundwater is contaminated must pay to have it removed or to find a new source of drinking water. Virtually all nitrate pollution comes from fertilizers used on crops so a way to deal with it problem is changing the way we farm.
Wha is the Kernza reducing?Evelyn is one of these researchers. She grew up in Minneapolis, Minnesota and as a high school student, she was surprised to learn that agriculture has a huge impact on soil and water quality, wildlife habitat, and biodiversity. She wanted to help protect the environment, so she studied Food Systems at the University of Minnesota.
A few years later, she joined a project that involved planting Kernza in rural areas to prevent and reduce nitrate contamination of drinking water. Farmers, city officials, water managers, and scientists worked together to find solutions. This project inspired Evelyn to study Kernza and nitrate for her master’s degree.
To see if Kernza helped absorb more nitrate from soil than annual crops, Evelyn and her colleagues ran an experiment. They planted plots of Kernza and other plots that rotated between corn and soybean every year. Plots with Kernza and corn were fertilized with nitrogen. Soybean plots were not fertilized.

Energy is needed for all biological activities, including those in humans and microbes. Many creatures consume other organisms while they are eating in order to acquire stored energy. But from where does the energy that food contains come? The source of all of this energy is photosynthesis. All life on earth depends on photosynthesis; this includes both plants and animals. It is the only biological process capable of converting solar energy, which comes from space, into the chemical molecules (carbohydrates) that every living thing uses to fuel its metabolism.
Only plants, algae, and a kind of bacteria known as cyanobacteria are able to carry out photosynthesis (Figure 1). They are referred to as photoautotrophs, which literally translates to "self-feeders utilizing light," because they produce their own food using light.

What kind of mutation might result in a the formation of the codon tga along the coding strand of dna?.
Answers
A point mutation might result in the formation of the codon TGA along the coding strand of DNA.
A point mutation is a type of mutation in which a single nucleotide in a strand of DNA is changed. This can occur due to errors during DNA replication or exposure to mutagenic agents, such as radiation or certain chemicals.
In the case of a point mutation, the change in a single nucleotide can affect the sequence of codons along the coding strand of DNA. A codon is a sequence of three nucleotides that encodes a specific amino acid or a stop signal for protein synthesis.
If a point mutation occurs in the middle of a codon, it can change the sequence of the codon and alter the amino acid that is encoded. For example, if a point mutation changes a G nucleotide to an A nucleotide in the codon GGA, the resulting codon will be TGA. This will change the amino acid encoded by the codon from glycine to cysteine.
In this way, a point mutation can result in the formation of the codon TGA along the coding strand of DNA. This type of mutation has the potential to affect the structure and function of the protein that is produced, depending on the location and nature of the mutation.
