Music the answer is music
Mendel’s model of inheritance involves the passing of individually separate units of inheritance, or genetics, from parents to babies.
Answer:
Receptor tyrosine kinases undergo autophosphorylation.
Explanation:
The receptor tyrosine kinases (RTKs) are proteins that undergo dimerization and autophosphorylation after binding with their corresponding ligands, thereby triggering downstream molecular signaling cascades. The RTKs bind with high specificity to ligands including growth factors, hormones and cytokines. In human cells, there are 58 types of RTKs proteins that function to regulate developmental pathways, and their dysfunctions have been associated with cancer progression.
Answer:
Nebula --> Protostar --> Supergiant --> Supernova --> neutron star
Explanation:
A high mass star starts as a big cloud of dust and gases. This cloud is called a nebula. When these clouds pick up some momentum, it condenses into a protostar.
The protostar will continue to condense because of its increasing gravity. The hydrogen atoms will start to collide and the pressure and temperature will trigger nuclear fusion. This is when the start will enter its main sequence where the outward force of nuclear fusion is balanced with its inward force. It will remain at this state until it runs out of hydrogen atoms.
When hydrogen stats to run out, the gravitational force will be greater than the force of nuclear fusion causing the core to shrink. Nuclear fusion then will start to occur outside the core and the star then expands into a Super giant.
The expansion of the star enables the star to create heavier elements like helium which then undergoes fusion itself and becomes a source of fuel for the star. When helium slowly depletes, it pulled into the core by gravity and all that is surrounding the core will explode , making it a super nova which marks the end of a star.
Two things can result from a supernova, a neutron star or a black hole. For bigger stars, the result would be a black hole. If the mass of the star was at least three times greater than our sun, then it will implode and become a black hole. If it is less, then the core would form a neutron star.
Answer;
-Genetic heterogeneity and epistasis.
Explanation;
-Marfan syndrome is a genetic disorder that affects the body's connective tissue that holds all the body's cells, organs and tissue together.
-Genetic heterogeneity is defined as mutations at two or more genetic loci that produce the same or similar phenotypes. Genetic heterogeneity may be either; allelic heterogeneity, which occurs when a similar phenotype is produced by different alleles within the same gene; or locus heterogeneity, which occurs when a similar phenotype is produced by mutations at different loci.
-A gene is said to be epistatic when its presence suppresses the effect of a gene at another locus. Epistatic genes are sometimes called inhibiting genes because of their effect on other genes which are described as hypostatic.
-From these descriptions the marfan syndrome demonstrates both genetic heterogeneity and epistasis.
