Answer:
Substances that conduct an electric current only under certain conditions are most likely to be METALLOIDS
Explanation:
Metalloids conducts electricity and allows the passage of electron which enhances their conductivity and make them suitable for it. Although this ability is only achieved when there is an increase in temperature in order to achieve this feat.
A electroscope is a device that detects static electricity by using thin metal or plastic leaves, which separate when charged.
Interphase is the phase before it starts mitosis in which the cell grows and replicates both it’s DNA and organelles. This phase takes up 78% of the cell’s lifetime = 561.6 minutes
Prophase takes up around 14% of the cell’s life cycle = 102.8 minutes
Metaphase involves 4% of the total mitosis cycle so = 28.8 minutes
Anaphase is the shortest phase of mitosis, taking up only 0.8% of the cycle = 5.2 minutes
Telophase is the final phase of the mitosis cell cycle and lasts around 3% of the total time = 21.6 minutes
Answer:
Answer is A. Expression of Cadherin gene in the cell that do not normally adhere to each other( or have low adhesion function).
Explanation:
Not that, the level of Cadherin expression influences the streght of adhesion and the type of Cadherin expressed, in determining the specificity and property of interaction.
Answer:
Kidneys : helps in forming urine
Ureter : They are connected to kidney and by peristaltic action transports urine from kidneys to bladder .
Urinary bladder : It is an hollow sac that holds the urine .
Urethra : transports urine from the bladder to outside of the body .
Explanation:
The human excretory system consists of : Kidney ,ureter ,urinary bladder and urethra .The figure is shown below .
Now , as far as functions are concerned we have :
Kidneys : They have excretory units called nephrons that further consist of :
- Bowman's capsule
- PCT (Proximal convoluted tubule )
- DCT (Distal convoluted tubule)
- CT (collecting tubule )
In nephrons urine is formed and via ureter it is transported to a hollow sac like structure called urinary bladder .
This bladder has muscles that cant remain contracted up to longer period )and then voluntary and involuntary it is excreted through urethra .
The process of passing urine is called Micturition .
