Answer:
If both parents are healthy carriers of the gene that causes cystic fibrosis, then their concern is justified, since they have a 25% (1:4) chance of having a child with cystic fibrosis.
Explanation:
The gene that produces cystic fibrosis is called CFTR, and its inheritance pattern is autosomal recessive.
Both parents may have the gene and not manifest the disease - healthy carriers - since the condition of homozygosity is necessary for cystic fibrosis to appear. However, they are likely to have children who are healthy, healthy carriers or sick with cystic fibrosis:
Genotype of healthy carrier parents is N/cf, where N is the normal gene and Qf is the abnormal gene.
N/cf X N/cf
Alleles N cf
N N/N N/cf
cf N/cf cf/cf
The chances of having:
- Healthy child are 25%.
- Healthy carrier child are 50%.
- Child with cystic fibrosis are 25%.
In this case, the concern of both parents is justified, since the probability of having a child with cystic fibrosis is 1:4.

Hello!! Your answer would be C - Medulla oblongata. The medullary respiratory center includes two groups of neurons that extend throughout the length of the medulla oblongata. They are called the ventral respiratory group and the dorsal respiratory group. The ventral respiratory group is responsible for regulating inspiration and expiration. The dorsal respiratory group stimulates the inspiratory muscles, like the diaphragm (near bottom of ribs). It also helps process sensory information related to the respiratory system. Neurons in the brainstem are a part of the pontine respiratory group which limits inspiration and help the rhythm of breathing. I hope I helped give you a better understanding. Have a great evening!!
Sickle cell sickness might've been identified with her passing since her body and cells weren't getting enough oxygen. Indications more often than not don't happen until after the age of 4 months. All individuals with sickle cell iron deficiency have excruciating scenes called emergencies. These can last from hours to days,
The first stage is TRANSCRIPTION, it is a process that takes place in the nucleus or in the cytosol, the DNA acts as a template to transcript it's information forming a new mARN molecule which contains the codons that codes an specific amino acid.
This mARN molecule will exit the nucleus and will be translated in the ribosomas that can be found in the cytosol or the Endoplasmic Reticulum. during TRANSLATION the mARN will be decoded to produce a polypeptide chain, this happens when the ribosome induces the binding of a tRNA anticodon sequences that are complementary to the mRNA codons, this will tell the ribosome which amino acid is needed to form the polypeptide chain.
It's important to clarify that in Prokaryotic cells, both of these stages take place in the cytosol since it doesn't have organelles binded by membrane unlike the Eukaryotic cells where the Transcription happens in the nucleus and the translation happens in the cytosol or endoplasmic reticulum
