Answer:
Stem cells have the ability to divide <u>through mitosis</u> and produce unspecified cells. Stem cells can be developed into a required tissue because of their ability of <u>differentiation</u>.
Explanation:
A stem cell is a cell that is in an undifferentiated state. This means that it has not specialized in a specific type that carries out a specific function of that tissue, which does not imply that stem cells do not have their own function. The concept of stem cell is due to the ability to originate specialized cells from one or more tissues, depending on the degree of potency or plasticity it has. They are found in all multicellular living organisms. Their main characteristic is that by reproducing through the process of mitosis (they divide into two cells) they can form more stem cells or differentiate, that is, they become specialized cells, in such a way that they are essential for the renewal of cells in different tissues. and to repair them.
Answer:
Sociobiologists
Explanation:
Sociobiologists are specialists in sociobiology, which is the study of social behavior found in various species of the animal world, including invertebrates, certain monkeys, and men. Sociobiologists assume that the gregarious way of life is advantageous for the adaptation of beings to the environment. Thus, they believe that each individual acts within their society in order to increase their own chances of survival and reproduction, as well as that of their "close relatives".
These professionals are responsible for seeking internal responses to individuals as a possible genetic predisposition to deviance.
The answer would be cretinism
Iodine is an element that vital for making thyroid hormone. Deficiency of iodine can cause hypothyroidism which can lead to growth retar..dation of the child inside the mother. This will cause the child develop a disease called cretinism. A child with cretinism will have a disturbance in growth and development.
Answer:
Explanation:
cystic fibrosis is an autosomal recessive disorder. When the child receives the defective gene from both of his parents, he suffers from cystic fibrosis. Because his parents are carriers. In recessive genetic disorder, the genes will be expressed when both recessive genes are present in one person. The person suffering from this disease have a lung infection and pancreatic dysfunction.
In this cystic fibrosis, genes are located in chromosome 7. The effective gene is the CFTR gene. The CFTR gene is present in the DNA and by transcription, this forms CFTR protein. This is a channel protein and transports chloride ion.
This CFTR protein transports chloride ions and it makes a balance in the cell membrane. These genes are commonly present in the epithelial cells. Outside the epithelial mucus is present to keep the cells moist.
The epithelium gets a lack of water and chloride due to the defect. Therefore cells need CFTR proteins also. This causes lung infection and pancreatic disorder.
Birds like to lay fossils. Salamanders have tails btw.
Hope this helped!
