you are studying the dna of a person who you know has two defective copies of the gene that encodes phenylalanine hydroxylase. you are surprised to find that this person also carries two defective copies of the gene for homogentisic acid oxidase. what disease symptoms will this person exhibit? (assume pathway intermediates are not available from sources outside the phenylalanine breakdown pathway.)
This person will exhibit symptoms of Alkaptonuria
Defective homogentisic acid oxidase gene causes alkaptonuria, and deficient phenylalanine hydroxylase gene causes phenylketonuria.
Due to an incomplete oxidation of tyrosine and phenylalanine caused by the genetic condition known as alkaptonuria, higher levels of homogentisic (or melanic) acid are produced. Ochronosis and phenylketonuria are other names for it.

It is at this time of conversion that energy is released. Glycolysis can occur in absence or presence of oxygenBoth fermentation and glycolysis produce ATP, and both are involved in the production of energy and supplying it to cellsWhat is Fermentation?
It is an anaerobic pathway- a common pathway in the majority of prokaryotes and unicellular eukaryotes. In this process glucose is partially oxidised to form acids and alcohol.In organisms like yeast, pyruvic acid formed by partial oxidation of glucose is converted to ethanol and carbon dioxide (CO2). ).

What about cells?There are many billions of cells in a human body. They give the body structure, absorb nutrients from meals, turn those nutrients into energy, and perform certain tasks. Prokaryotic cells and eukaryotic cells are two different types of cells. Although prokaryotic and eukaryotic cells have different shapes (see prokaryote, eukaryote), they are quite similar in terms of their molecular make-up and functions. Proteins, polysaccharides, and nucleic acids make up the majority of the molecules in cells. The cell membrane, the nucleus, and the cytoplasm are the three components that make up a cell. Intricate arrangements of microscopic fibers and hundreds or even thousands of tiny, unique structures known as organelles can be found in the cytoplasm. The parasitic bacteria Mycoplasma gallicepticum, which inhabits the respiratory, genital, and urinary systems of primates, is thought to be the tiniest known creature capable of autonomous development and reproduction.

'ntraspecific competition among planthoppers. intraspecific competition among planthoppers . results in increased development time. Occurs via resources rather than interference. Results in reduced survivorship. All the above. All of the choices are correct.
At large population densities, intraspecific competition can be fierce and detrimental to fitness. Low survival rates, sluggish growth, diminished fecundity, and decreased reproductive rates are caused by high population density.
What about intraspecific competition?When members of the same species compete against one another, this is known as intraspecific competition. Depending on the type of competition that exists, each individual within the species will be affected differently by it. Competition in a "contest" might be active or passive and have many effects. Members of the same species may compete with one another for food, shelter, water, and mates in intraspecific competition. Members of various species compete with one another across interspecific boundaries. For instance, various species of predators may engage in competition over the same prey. Pertaining to or occurring within a single species. Because the resource requirements of members of the same species are relatively comparable whereas those of different species are less similar, intraspecific rivalry tends to be more powerful than interspecific competition. One common theory is that intraspecific competition for scarce dietary resources is the reason why the egg yield of the individual parasite declines with population density. Many sea urchins may experience changes in growth, reproduction, and morphometry due to intraspecific competition). Similar results from C. rodgersii experiments show a high degree of plasticity in development and morphology in many habitat types. Interspecific competition has a negative overall effect on both participating species (a -/- interaction). In other words, if the other species didn't exist, each one would thrive more.

What is sickle cell anemia?Sickle cell is an inherited disease caused by a defect in a gene. A person will be born with sickle cell disease only if two genes are inherited—one from the mother and one from the father.
Sickle cells that block blood flow to organs deprive the affected organs of blood and oxygen. In sickle cell anemia, blood is also chronically low in oxygen. This lack of oxygen-rich blood can damage nerves and organs, including kidneys, liver and spleen, and can be fatal.
Stem cell or bone marrow transplants are the only cure for sickle cell disease, but they're not done very often because of the significant risks involved. Stem cells are special cells produced by bone marrow, a spongy tissue found in the centre of some bones.

mutated
O haploid for the trait
O homozygous for the trait
heterozygous for the trait
The term applies to an individual who possesses two recessive alleles for the same trait and is homozygous for the trait. Option B.
The genotype is formed by the combination of alleles that an organism has. If the paired alleles are the same, the organism's genotype is said to be homozygous for that trait, and if they differ the organism's genotype is said to be heterozygous. Homozygosity also refers to a genotype consisting of two identical alleles of a gene for a particular trait. An individual can be homozygous dominant or homozygous recessive.
In complete dominance, only one allele of the genotype is present in the phenotype. In codominant cases, both alleles of a genotype are present in the phenotype. In the case of imperfect dominance, the phenotype shows a mixture of genotypic alleles. Homozygous and heterozygous are terms used to describe a pair of alleles. Individuals who have two identical alleles are said to be homozygous. Individual organisms with different alleles are said to be heterozygous.

The one difference between eukaryotic cells and prokaryotic cells is that only eukaryotic cells have specialized organelles enclosed in membranes.
The single membrane layer surrounds the prokaryotic cells but there are two surrounding membranes in the case of eukaryotic cells which are the plasma membrane and the nuclear membrane. The cell wall in the plasma membrane is made up of carbohydrates, lipids, proteins, and certain amino acids, whereas chitin and cellulose combine together to make up the cell wall of eukaryotic cells. The cell membrane of the prokaryotic cells contains the Respiratory enzyme while the cell membrane of the eukaryotic doesn't contain this enzyme.
