If soil have all nutrients, then why do we need to replenish it.
Urgent!!!

Answers

Answer 1

Answer:

because when we griw theplants over there all the nutrition will be already consumed so, we need to replenish it time to time.

Answer 2
This is due to several reasons:

(1) Nutrient uptake by plants

Plants take up several mineral ions such as nitrates(for general growth), phosphates (for root growth), magnesium (for chlorophyll).

In order for the plant to keep growing healthily, the soil has to be constantly replenished to supply them with the mineral ions required.

(2) Soil erosion/Percolation

Heavy precipitation, can result in the washing away of nutrients via percolation.

Answers

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

Explanation:

Subduction describes convergent boundaries.

What is convergent boundaries?

Lithospheric plate borders that are convergent are those where the plates are moving in the same direction. These regions' plate clashes have the potential to cause earthquakes, volcanic eruptions, and crustal deformation.

The thicker, less dense continental plate pushes aside the thinner, more dense oceanic plate when the two plates contact. Subduction is the process by which the oceanic plate is pressed into the mantle.

The oceanic plate is pushed into regions with increasing temperatures as it falls. Materials in the subducting plate start to approach their melting temperatures and partial melting starts to take place at a depth of around 100 miles (160 km).

Therefore, Subduction describes convergent boundaries.

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.

Answers

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.

what is the center of the DNA strand?

Answers

Answer:

It exhibits traits and metabolic instructions of the cell.

Explanation:

A DNA strand is a thin long molecule, with an average width of just around two nanometers. The remarkable thinness of the DNA strands allows them to be bundled very tightly fitted inside cells. Once DNA has been replicated adequately during the process of cell division, it is further wrapped together under a mechanism known as supercoiling. A non-condensed DNA is further condensed during supercoiling using a special protein known as a histone. A part of DNA packed around a large cluster of histones is called a nucleosome. Additional condensation leads to a chromosome or the most compact type of DNA that fits into the nucleus. It is also worth noting that this wrapping does not merely align DNA into a cell, but serves other objectives such as protecting DNA, thus ensuring metabolic instructions to the cell.

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?

Answers

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.

Answers

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.

Where does an ectopic pregnancy happen? It's considered an ectopic pregnancy whenever the fertilized egg implants outside of your uterus. The egg is meant to travel down the fallopian tubes and imbed itself into the wall of your uterus, where it can begin to develop.

Yes, I agree with the given statement.

Explanation:

Plants undergo the process of photosynthesis for the production of their food. In this process, they require the presence of sunlight, carbon dioxide, water, minerals, and chlorophyll. The process of photosynthesis is possible only during the day because sunlight is one of the major components. Carbon dioxide is taken in by the plant through the stomata from the environment. The oxygen is formed as a product of the process and is released in the environment. This process becomes impossible during the night because of the absence of sunlight. The entire process sums up to that the plants give out oxygen during the day and give out carbon dioxide during the night.
