Complete question:
If the recessive allele for cystic fibrosis is represented as c, classify the following genotypes as homozygous dominant, homozygous recessive, or carriers: CC,Cc, and cc. State which one has the phenotype of cystic fibrosis.
Answer:
CC - homozygous dominant
cc - homozygous recessive
Cc - carriers
cc will have the phenotype
Explanation:
Cystic fibrosis is an autosomal recessive disorder that affects the production of mucus in the body, primarily affecting the lungs and digestive system.
Because it is autosomal recessive, an affected individual needs to inherit 2 copies of the faulty gene. The presence of just one normal copy of the gene is sufficient not to cause the disease
In genetics, the dominant allele is usually displayed as a capital letter and the recessive as a small letter. Homozygous means someone has 2 copies of the same allele, heterozygous means they have different alleles. Therefore, CC - homozygous dominant, cc - homozygous recessive, and Cc - carriers. Only those with a cc genotype will be affected, as the presence of one dominant allele is enough to block the phenotype
Nicole was as diagnosed with Leigh Syndrome (LS). Leigh syndrome is said to be “a severe neurological disorder that is characterized by the degeneration of the central nervous system and is associated with a nuclear mutation in the SURF1 gene”. Which leads to a defect in a protein found in the mitochondria. It affects a protein normally found in cellular organelles, most likely the Mitochondria organelle which is involved in energy production. The aforesaid syndrome is passed down through autosomal recessive conditions. In the case of Kenneth and Vicki (Nicole’s parents), both of them may have working and nonworking copies of the gene and unfortunately, both of them passed down the nonworking gene to Nicole.
Answer is D. The phosphate group of membrane lipids are negatively charged.
The cell or plasma membrane is a bilayer of phospholipids. The two phospholipids layers are opposite to each other. Each phospholipid molecule consists of a phosphate group and a lipid. The phosphate form inner and outer layers of hydorphilic and are negatively charged 'heads' and lipid forms the tail, hydrophobic and non-polar. Since phosphate is negatively charged it repels negatively charged molecules and do allow them to pass through it.
Answer:
1 m/s²
Explanation:
Kg is the unit of mass and Kg.m/s² is the unit of force.
Kg.m/s² is equal to Newton.
Kg.m/s² = N
The given expression is shows that force is divided by mas which means that the resultant value will be acceleration.
Because,
Acceleration can also be determine through following formula,
F = m × a
a = F/ m
Thus,
1 Kg.m/s² / 1 Kg
1 m/s² .
Acceleration will be 1 m/s².
