Answer: c.no-till farming
Tillage is a method of mechanical agitation of soil before sowing seeds for growth of new crops. Tillage is done to reduce soil compaction. But there are some disadvantages associated with this it causes erosion of upper layer of soil, it decreases the minerals composition of soil and disturbs the natural microbial growth. No-till method is an agricultural practice in which the stalks are left on the crop fields to anchor the topsoil. It avoids the mechanical or physical agitation of soil. This is basically done to prevent soil erosion so, that roots can hold the soil in place. This technique is advantageous over tillage method. As, it retains the natural physical properties of soil. It increases the water retention capacity of soil. It increases the yield of the crops.
a. Motor neuron with synaptic terminal
b. Synaptic vesicle with neurotransmitter
c. Receptor protein with action potential
d. Motor end plate with deactivation enzyme
Ans.
The given diagram represent chemical synapse, which is defined as biological junction between two neurons and is responsible for the exchange of neural signals. The structure labeled with question mark is synaptic vesicle. The synaptic vesicles are small sac like structures that contain neurotransmitters. These neurotransmitters are released by these vesicles through expcytosis and bind to receptors present in another neuron.
Thus, the correct answer is option b). synaptic vesicle with neurotransmitter.'
Blood that is directed back towards the surface of energy.

Answer:
A noticeably thin deer, with respiratory symptoms such as coughing and very weak, may be diagnosed with Bovine Tuberculosis, which is treated with specific antibiotic therapy. Other symptoms are fever, loss of appetite and appearance of body nodules. Complementary treatment is based on the isolation of the affected deer.
Explanation:
Bovine tuberculosis (BT) is a multi-mammalian infection caused by contact with Mycobacterium bovis, a non-sporulated and immobile acid-alcohol resistant bacillus.
BT is a chronic granulomatous infection that can first affect the lungs, producing cough and respiratory distress, associated with fever and progressive decrease in weight and physical activity.
Treatment consists of specific antibiotics for mycobacteria, such as Clarithromycin, Rifampicin and Etambutol. Isolation of sick deer may help prevent the spread of infection to other individuals.
Another disease that can cause similar symptoms in deer is Epizootic Haemorrhagic Disease, caused by an RNA virus called Orbivirus, which prior to its haemorrhagic phase causes the general symptoms of hyporexia, weight loss, depression and cough.
TRNA
tRNA
O
nRNA
tRNA( Transfer RNA) molecules carry amino acids to the site of protein synthesis
Explanation:
Proteins are the building blocks of the cells. The process of protein synthesis involves transcription and translation of the genetic information stored in the DNA. After the process of transcription which is the process to get RNA molecules from the DNA. After this process, during protein synthesis tRNA carries amino acids to the ribosomes is the structure where protein synthesis takes place.
