Answer:
Explanation: Plant cells that are being placed first in a medium for the purpose of the tissue culture are differentiated cells. Pluripotent cells or cells that are able to develop into all the specialized cell types and structures of plants are being produced by undifferentiated cells.
Answer:
1. hyaline cartilage
2. a fibrocartilage
Explanation:
In endochondral ossification to produce fetal vertebrae, cartilage is substituted with a bone. The process of endochondral ossification includes the development of hyaline cartilage, also called the cartilage model. The hyaline cartilage develops from the chondroblasts derived from mesenchymal cells. The division of chondroblasts results in the growth of hyaline cartilage. It is followed by the development of the primary ossification center wherein the cartilage tissue is replaced with the bone matrix.
During the repair of these bones, a fibrocartilage callus is formed. Fibroblasts present in the site where the bone is broken produce collagen fibers and the cells derived from periosteum develop into chondroblasts and begin to produce fibrocartilage in this region. The fibrocartilage and collagen fibers together make the fibrocartilage callus that joins the broken ends of the bone.
Answer: 5. Simple sugars are carbs with one (monosaccharide) or two (disaccharide) sugar molecules. Many healthy foods like fruit and vegetables naturally contain sugar and shouldn't be avoided as they benefit your health. 6. It's a Gas-Carbon Dioxide and Oxygen. When the cells of your body burn fuel (sugar), they produce a gas-carbon dioxide. When the cells of a green plant make sugar, they need a gas-carbon dioxide.When the cells of your body burn fuel (sugar), they produce a gas-carbon dioxide. When the cells of a green plant make sugar, they need a gas-carbon dioxide. During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose. Photosynthetic cells are quite diverse and include cells found in green plants, phytoplankton, and cyanobacteria. During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen.
Explanation:
Answer:
B. The nucleus is damaged.
Explanation:
Eukaryotic cells contain a membrane-bound nucleus and numerous membrane-enclosed organelles. DNA is present in the nucleus of the cell. If the nuclear membrane is ruptured/damaged then the nucleoplasm along with the DNA will openly float around the cytosol.
