Golgi apparatus is a complex cytoplasmic structure made up of smooth membrane saccules or cisternae, a network of tubules with vesicles and vacuoles, which takes part in membrane transformation, secretion, and production of complex biochemicals, that helps process and package proteins and lipid molecules.
Answer:
Explanation:
Science is a tapestry and when you yank at one thread the whole thing may need to be rewoven but sometimes you have to yank the thread. I think the comparison means that scientists may misinterpret things but at the same time may discover new ways to view the universe.
Vesto Slipher contributions were that he took spectra of the spiral nebulae and discovered galactic redshifts. Slipher discovered that most of the objects were moving away from us at high speeds. As a result of this discovery Hubble correlated Slipher’s measurements with distance. He measured by other means to formulate his law which was that the farther away the galaxy was the Faster it was moving away From us.

Answer:
D) Genes are found in specific locations on a chromosome.

- A chromosome contains hundreds to thousands of genes.
- Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes.
- A trait is any gene-determined characteristic and is often determined by more than one gene.
- Some traits are caused by mutated genes that are inherited or that are the result of a new gene mutation.

Answer: A . Has its collagen fibers randomly orientated.
Explanation:
In the microscopic anatomy of the bone, an osteon (basic microscope unit of the bone) can be arranged into two categories; woven bone or lamellar bone.
As the name suggests woven bone is characterized by the random orientation of the collagen fibers . These collagen fibers haphazardly form to give the visual appearance of an intertwined (woven) network of collagen fibers.
Due to the randomness of the collagen fibers orientation woven bone is thus mechanically weaker than lamellar bone. Woven bone is formed/produced when osteoblasts produce osteoids rapidly within the bone matrix thus woven bone has the ability to form quickly as needed.
Woven bone is thus immature bone or pathologic bone with no stress orientation, it has a high percentage of osteocytes per unit volume and a high rate of turnover.
