Answer:
The correct answer will be option-neural tube, hindbrain, metencephalon,
Explanation:
The development of the brain during the embryogenesis takes place by the formation of a neural tube or the predecessor of the central nervous system.
The neural tube arises from the ectoderm layer of the gastrula where the anterior portion of the neural tube forms the brain.
The neural tube development results in the formation of three sacs filled vesicles in which the fist vesicle forms the forebrain, second forms the midbrain and the third vesicle forms the hindbrain.
Later development process divides the hindbrain into two new portions called metencephalon and myelencephalon where the metencephalon forms the cerebellum portion of the brain.
Thus, the selected order is the correct order.
Answer:
Tropomysin, calcium
Explanation:
Tropomysin is a protein that prevents muscle contraction hence acts as a contraction inhibitor. It wraps around the actin blocking the binding sites for myosin on the actin.
Muscle will only contract when they get a rush of calcium ions.
The calcium ions binds to troponin, the troponin changes its shape. The change in shape will remove tropomyosin from the binding sites allowing myosin to bind on the actin leading to muscle contraction.
1) Plant and animal cells are both categorized the same as prokaryotes or eukaryotes based on the presence of a particular membrane-bound organelle – the nucleus, bounded by the nuclear membrane.
Explanation:
Prokaryotic cells are distinctive by the lack of a definitive nuclear structure or nucleus. Eukaryotic cells have a definitive nucleus with a nucleolus and DNA strands and stores the genetic information or the genes which are encased inside the nuclear envelope or membrane. Prokaryotic cells have their DNA in their cytoplasm since they lack a nucleus.
2) The organelles/structures that are found only within plant cells are chloroplasts and central vacuole.
Chloroplasts are exclusively found only in plants. The chloroplasts contain the chlorophyll, the green pigment which helps the plants to absorb solar or light energy trapped from the sun to carry out photosynthesis.
The central vacuole, the largest organelle, membrane-enclosed sac filled with fluid called cell sap. The central vacuole provides basic support and structure, maintain cell pressure, store reserve food and waste materials, and contains enzymes which aid various cellular activities.
Answer:
Restriction enzyme cuts out gene of interest, Gene is inserted into plasmid (circular) DNA of bacteria using same restriction enzymes, DNA ligase seals DNA together, Plasmid is inserted into bacteria (transformation)
The goal for both is to Change the DNA of the person with the genetic disease
