Answer:
Chromosomes become visible, crossing-over occurs, the nucleolus disappears, the meiotic spindle forms, and the nuclear envelope disappears.
Explanation:
The duplicated homologous chromosomes pair, and crossing-over (the physical exchange of chromosome parts) occurs.
I believe the most appropriate is a selective medium and differential medium. Selective medium types are formulated to support the growth of one group of organism, but inhibit the growth of another. Blood agar is a differential medium that distinguishes bacterial species by their ability to break down the red blood cells included in the media. Blood agar is often used to distinguish between the different species of pathogenic streptococcus bacteria.
Answer:
Bone extracellular matrix consists of osteocalcin, glycosaminoglycans, collagen, water and bone mineral.
Explanation:
Bone is one of the important connective tissue and provide sites for the muscle attachment.
The extracellular matrix of bone consists of 30% organic matrix. The organic matrix includes glycoproteins, glycosaminoglycans and proteoglycans. The calcium binding protein of extracellular matrix is osteoclacin. Type I and type V collagen is present in the extracellular matrix. Nearly 25% water is present in the bone extracellular matrix. Hydroxyapatite is the bone mineral present in the extracellular matrix of bone.
Answer:
Oxygen is used to break down sugar and sugars release energy
Answer: Eratosthenes was the first to propose a system of longitude between 260 - 201 B.C. Greek astronomer Hipparchus was the first to use longitude to define a location (along with latitude). Longitude lines run from the North and South Poles and are measured by one arcdegree. These lines are called meridians. Unlike latitude, longitude was not able to be determined until the 18th century as a result of difficulty. The Royal Observatory in Greenwich, England marks zero degrees longitude. Longitude was accepted after the 18th century after it was able to be determined and measured by mathematics.
