When you shower with hot water, everytime you get out the shower, outside it is cold, but inside it is hot due to the hot gas particles. When you shower with cold water, it is the opposite.
Answer:
- Parallel arrangement of collagen fibers: Dense regular connective tissue (CT)
- Transports oxygen and hormones: Bood
- Contains chondrocytes: Cartilage
- Stores minerals: Bone
- Random arrangement of collagen fibers: Dense irregular connective tissue (CT)
- Cushions and insulates: Adipose tissue
Explanation:
The dense regular connective tissue (CT) is a type of connective tissue composed of collagen fibers arranged in a parallel pattern which provides a strong association between tissues (e.g., tendons and ligaments). Conversely, in dense irregular connective tissue, collagen fibers are not arranged in parallel bundles (e.g., the dermis in the skin and lamina propria in the gastrointestinal tract). Cartilage is a type of flexible connective tissue composed of chondrocytes, the unique type of cells in cartilage tissues. Chondrocytes are responsible to produce and maintain the collagen extracellular matrix (ECM) which is composed mainly of collagen and proteoglycans (proteins coated with sugar molecules). Bone is a type of connective tissue composed of cells (i.e., osteoblasts, bone lining cells, osteocytes, and osteoclasts), fibers and ground substance. Bones have many functions including, among others, store minerals (calcium and phosphate), protect internal organs, allow movement, provide internal support, etc. Blood is a type of connective tissue (because blood has a matrix) whose main function is to transport oxygen (O2) and essential substances (e.g., nutrients, hormones, etc) to the tissues, and carbon dioxide (CO2) from the tissues to the lungs. Blood contains two different types of cells: red blood cells (i.e., erythrocytes) and white blood cells (i.e., leukocytes). Finally, adipose tissue is a special type of connective tissue in the subcutaneous layer that helps to cushion and insulate the body (providing insulation from heat and cold). Adipose tissue is composed mostly of adipocytes, which are cells that store energy in the form of lipid molecules.
D: interphase
during this phase , the chromosomes undergoes duplication of chromosome of 1 chromatid into chromosome of 2 chromatids , then the cell is ready for the cellular division.
Answer:
c. Taq polymerase is heat-stable and can withstand high temperatures.
Explanation:
The process of PCR amplifies a small amount of DNA into multiple copies. For the purpose, the sample DNA fragments are denatured at higher temperature conditions (around 95 degrees Celsius). This separates the two strands of the sample DNA which in turn serve as a template. Taq polymerase from a thermophile can withstand the extremes of the temperature conditions required for denaturation of sample DNA. Unlike the DNA polymerases from other organisms such as humans, Taq polymerase is not denatured at higher temperatures.
Therefore, Taq polymerase can be used as an enzyme of primer elongation to amplify the DNA by PCR.
