"Severe combined immunodeficiency (SCID)" can be caused by "failure of VDJ recombination".
Option D
<u>Explanation</u>:
- "SCID" is "inherited immune system disorder" which happen due to abnormalities in the response of both T and B cells which are needed for the proper functioning of the immune system.
- VDJ occurs in genetic recombination occurring in the early or developing stages of lymphocytes.
- Somatic recombination is also a part of VDJ which results in immunoglobulin's, which is "defining feature" of the immune system and the same which causes severe combined immunodeficiency.
Answer:
The correct answer is - salience network.
Explanation:
A network that is essential to make a center or collection of the brain that identify and select which stimuli is most deserving for attention is salience network. It is the brain network that is accountable for the keeping eye on the important changes in cognitive and biological system.
The key nodes are present in the insular cortex of this network which is important in order to recognizing the relevant stimuli and coordinating such stimuli in response to these behaviorally stimuli.
Thus, the correct answer is - salience network.
The answer is true. Bc the stronger they are the more likely they will survive.
Answer:Isotonic, Hypotonic, and Hypertonic Solutions. Water
Explanation:Isotonic, Hypotonic, and Hypertonic Solutions. Water moves readily across cell membranes through special protein-lined channels, and if the total concentration of all dissolved solutes is not equal on both sides, there will be net movement of water molecules into or out of the cell.
In agroecosystems, farmers practice monoculture. It is a practice of growing one type of crop in the same field year after year. Monoculture is an attempt to check herbivores from eating crops. As a result population of herbivores get reduced from the food webs. Using different types of agro-chemicals such as insecticides, pesticides, weedicides also reduces number species. Therefore, the most unusual characteristic of food webs in agroecosystems is lack of biodiversity.
