Answer:
These group of muscles called erector spinae muscles arises from a tendon in the sacral area and pelvis, it extends up to the occipital bone.
Erector spinae muscles originates from the SPINOUS PROCESSES of T9-T12 of the thoracic vertebrae and inserts into the SPINOUS PROCESSES of T1-T2 of the cervical vertebrae
They therefore run vertically on either side of the spine (medially and laterally).
the air's oxygen is partially replaced by carbon dioxide. This is because of the gas exchange that occurs so we can live.
Answer: The answer is that the phenotypic ratio among phenotypes produced from an F1 X F1 dihybrid cross is 9:3:3:1.
Explanation:
Independent assortment of genes explains how alleles on different chromosomes arrange independently of one another during gamete formation.
So, a dihybrid cross involving TWO characters (e.g Seed color & seed shape) would have its respective alleles DISTRIBUTED whether dominant or recessive, for crossing to occur and yield varying proportion of offspring in the well spread ratio of 9:3:3:1; making it a consequence of independent assortment of genes
Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, this lifetime ranges from only a few million years (for the most massive) to trillions of years (for the less massive), considerably more than the age of the universe. ^
Small, relatively cold, low mass red dwarfs burn hydrogen slowly and will burn for hundreds of billions of years
Massive hot supergiants will live for just a few million years.
A mid-sized star like the Sun will remain on the main sequence for about 10 billion years. Hope tis helps!!
The commence is off base with regards to the enthusiasm for creating fake blood. The intrigue is on the grounds that the timeframe of realistic usability of put away blood is extremely constrained. The other intrigue is concerning transfusion responses related with red platelet antigens that can bring about lethal responses and cause delays in finding good blood that hazard understanding lives. At present the rate of securing HIV disease through blood transfusions has been computed to associate with one case for every a million or two million transfusions. That viewpoint has been tackled with respect to testing however alternate issues still remain and they persuade the proceeded with look for simulated blood. Other developing infections like Zika and other obscure infections additionally makes a requirement for such research.
