1. Which of the following is NOT a result of convection current? a) The air in a room is cooled by an air conditioner b) Wind blows towards the beach from the sea. c) The water in a kettle is heated and boils d) The wax covering an iron rod melts when the rod is heated.
Answer:
its D
Explanation:
because conduction happens through solids and the others are obviously conventional current
The wax covering an iron rod melts when the rod is heated ( D ) is not a result of convection current
Convection is the transfer of heat energy from an area of higher concentration to an area of lower concentration and it occurs in fluids and gases. while conduction is the transfer of heat energy from one object to another through the direct contact of the objects and this occurs between solids.
The transfer of heat from the heated rod to the wax covering occurs because of the direct contact the wax has with the heated rod therefore it is conduction and not a convection current.
Hence we can conclude that The wax covering an iron rod melts when the rod is heated is not a result of convection current

How would the coils in the middle of the diagram
change to show a longitudinal wave with higher
energy?
They would be farther apart.
They would be closer together.
They would be shaped like a hill.
They would be shaped like a valley.
Answer:
The correct answer is - option C.
Explanation:
A longitudinal wave with higher vitality have more noteworthy plentifulness. Abundancy is the separation between the covering and trough of the wave. The crust is the topmost layer of the wave while trough is present at the bottom portion of the wave.
In the event that the separation among crust and trough of the wave is higher so the amplitude is likewise more prominent and we can say that the wave contains a high measure of vitality and the other way around. The state of the structure of the wave simply like a hill.
Thus, the correct answer is - option C.

Chloride ions, Cl-, follow actively transported Na+ ions from the nephrons into the blood. Would you not expect the Cl- concentration to decrease as fluids are extracted along the nephron?
Answer:
Bicarbonate ion, HCO3- (which has a similar charge to chloride ions) also follow sodium ions into the blood. Also, potassium ions, K+ are transported into the nephron so some chloride ions and bicarbonate ions remains in the nephron to balance the charge.
Explanation:
Sodium is the primary positively charged electrolyte in extracellular fluid. Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride. Water is also reabsorbed in order to balance osmotic pressure
When sodium ions are reabsorbed into the blood, few of the substances that are transported with Na+ on the membrane facing the lumen of the tubules include Cl- ions, Ca2+ ions, amino acids, and glucose. Sodium is actively exchanged for K+ using ATP on the basal membrane.
In the distal convoluted tubule, K+ and H+ ions are selectively secreted into the filtrate, while Na+, Cl-, and HCO3- ions are reabsorbed to maintain pH and electrolyte balance in the blood.
Some chloride ions remains in the nephron to balance the charge of the secreted K+ ions and also due to the bicarbonate ions that are removed.
The concentration of Chlorine decreases as fluids are extracted along the nephron because it is not soluble in water. With an increase in the fluid extraction along the nephron, there is the reabsorption of more water and since Chlorine cannot be diluted by water, its concentration decreases. With the more reabsorption of water and increase in its concentration as the fluid moves through the nephron, the relative concentration of chlorine reduces.
This gradient is mainly caused by NaCl and urea. NaCl is transported by the ascending limb of Henle's loop which is exchanged with the descending limb of the vasa recta.

A female had tubular pregnancy and had to remove her oviducts. Will this affect her in anyway with respect to reproduction ? justify?
Reproduction will be highly affected.
Since there are two oviducts one will be removed as a result of the ectopic pregnancy.
Hence, there will be a defect in the carrying of the ovum from the ovary to the uterus. There will be delivery of the ovum only in the the unaffected oviduct. This can lead to non-fertility.
Ectopic pregnancy is a condition in which there is an implantation of the zygote in a location other than the the uterus.

The question is incomplete. The complete question is as follows:
The unusual patterns on a silk moth’s wings are one of the most stunning examples of mimicry in the wild. Mimicry occurs when an organism develops a physical characteristic or behavior similar to a protective trait in another species. What do you think these moth wings mimic? Why do you think this kind of mimicry can protect the moth?
Answer:
The silk moth's mimic the physical characteristics such as changes in wings pattern that resemble another moth species that is dangerous or unpalatable to predators.
This unusual change in wings pattern provide camouflage to the silk moths and prevent predators. Predators get confuse because of the mimic spcies and consider them as toxic or untasty and won’t attack.
Answer:
The moth wings actually look like the eyes of a much larger animal. This mimicry may protect the moth from predators.
