Oceans

Composed of salt water, oceans cover 70% of the Earth’s surface, and, in reality, are one “World Ocean” that we’ve broken up into five smaller divisions. They are, in descending order by size, the Pacific, Atlantic, Indian, Southern (or Antarctic), and Arctic. These are what we might term political or horizontal divisions, rather than physical or biological vertical divisions. Since the 1700s, there have been many mentions of some sort of southern ocean and recently, attempts have been made to formalize the Southern Ocean, given the importance of ocean currents. The Southern Ocean has the strongest and longest current in the world which circumvents Antarctica.

Seas

Next up in size are seas. A sea is also made up of salt water, and is a large body of water entirely or partially surrounded by land. This isn’t to be confused with “the sea” which is generally how people refer to the collection of oceans. It’s a matter of specificity: if you’re not being specific, you might take a holiday by the sea. If you are being specific, you might sail across the Mediterranean Sea or the Pacific Ocean. But you wouldn’t go to the Pacific Sea.

A few seas would be the Mediterranean, Bering, Norwegian, Arabian, and so on. You’ll notice that these are often just bits of the ocean that are mostly surrounded by land that we’ve named. The Caspian Sea is sometimes classified as a salt lake, although it’s quite large.

Wetlands and Deltas

Now before we move inland to talk about lakes, let’s first discuss wetlands and deltas. A delta is where a river meets the ocean, or sometimes a lake. Usually, the river fans out as it approaches sea level. They’re formed when a river carries a certain amount of sediment at a higher rate and when it reaches a stagnant body of water, it forms a delta.

small streams of water flow from inland toward the ocean

A wetland is different from a delta, although wetlands often form near the shore. Wetlands form unique ecosystems that are inundated by water and contain an especially high degree of aquatic plants. Wetlands have been considered the most biologically diverse ecosystem.

Lakes

Okay, back to more traditional bodies of water. Lakes are the next largest after seas. A lake is always landlocked, meaning it’s completely surrounded by land, except for a river that feeds or drains the lake. Apparently, scientists can’t decide on a specific differentiation between lakes and ponds, so generally, we go by size: lakes are bigger. It depends on who you ask, but some people will say that a lake is a body of water that’s 5+ acres in surface area, or up to 99+ acres in surface area. Almost exclusively, lakes are freshwater, unlike seas, bays, harbors, or anything that’s made up of sea water.

Lakes are formed for different reasons. Most often, lakes were formed (we think) by retreating glaciers that carved up the land. Sometimes they’re formed by the movements of tectonic plates. If you want to learn more about tectonic plates, check out our video on them!

A fun type of lake is the oxbow lake. This is formed when a meandering river (which usually occurs in a low-lying plain) bends back on itself forming a U or horseshoe. The edges continue to erode, and eventually, the stream meets itself again, and the running water bypasses the loop and continues on the shorter route. This leaves the water in the loop to form a lake. In Australia, they call them billabongs.

Ponds

Still going down the list in size we have ponds next. These are freshwater and are often manmade. They’re formed in a variety of different ways and include koi ponds and other aesthetic purposes, as well as uses for farming.

Of course, there are many other types of bodies of water, such as fjords, wadis, runs, subglacial lakes, reservoirs, lagoons, kills, etc. But sadly, we don’t have time to talk about all of those right now so you’ll have to go research them on your own!

The Boiling River

But I promised you I’d talk to you about the boiling river! Legend has it that when the Spanish conquistadors went into the Amazon rainforest in search of gold, few returned. Those that did told horror stories of man-eating snakes, diseases, dangerous creatures, and a river that boiled. Hundreds of years later, a young Peruvian named Andrés Ruzo grew up hearing these tales and was determined to find this river. He eventually worked for National Geographic and would spend years researching and talking to locals about the boiling river. Mostly, he was laughed at for chasing old legends. But eventually, deep in the rainforest, he finally found the boiling river, with the help of the local guardian shaman. So yes, it does exist, although “boiling” is a bit hyperbolic. It is, however, huge, extremely hot, quite long, and non-volcanic. It’s classified as a “thermal river” and isn’t actually any hotter than other thermal bodies of water.

Answer:

A. Fast growing crops, heavy rains

Explanation:

Fast growing crops will increase soil nitrates, while heavy rains will decrease soil nitrates.

Animal manure has organic waste containing nitrogen that acts as a source of nitrate in the soil and growing crops absorb nitrate from the soil. Thus option C is correct.

What is nitrate?

Nitrate is an organic compound of nitrogen that is present in the fertile soil and absorbed by the plants. The Source of nitrate is humus and fertilizer. Humus is obtained from animal manure, and dead and decaying animal and plant bodies.

Fast-growing crops absorb the nitrate from the soil and use it for development and growth such that nitrate decrese in soil. So option C is correct.

Transient ischemic attacks (TIAs) are sometimes preceded by major strokes.

Transient ischemic attacks (TIAs) are brief episodes of neurological dysfunction caused by a temporary disruption of blood flow to the brain. They are often considered warning signs or precursors to more severe strokes. TIAs share similar symptoms with strokes, such as sudden weakness or numbness on one side of the body, slurred speech, and difficulty with coordination or balance. However, unlike a major stroke, the symptoms of a TIA typically resolve within a short period, usually within a few minutes to a few hours.

TIAs are a warning sign that the blood supply to the brain may be compromised, and they indicate an increased risk of experiencing a major stroke in the future. It is estimated that about one-third of individuals who experience a TIA will go on to have a full-blown stroke if preventive measures are not taken. Therefore, recognizing and treating TIAs promptly is crucial in preventing more severe and potentially debilitating strokes.

The underlying causes of TIAs are often similar to those of major strokes, such as atherosclerosis, which is the buildup of plaque in the blood vessels. Other risk factors for TIAs include high blood pressure, diabetes, smoking, and high cholesterol levels. Addressing these risk factors through lifestyle modifications and medical interventions can help reduce the chances of both TIAs and major strokes.

Answer:

Genetic engineering is made possible by recombinant DNA technology. Organisms that have altered genomes are known as transgenic. Most transgenic organisms are generated in the laboratory for research purposes. For example, "knock-out" mice are transgenic mice that have a particular gene of interest disabled.

The most common proteins produced by transgenic organisms are albumin, fibrinogen, and human antithrombin.

What do you mean by Transgenic organisms?

Transgenic organisms may be defined as those organisms in which foreign DNA has been introduced by recombinant-DNA technology with the help of plasmid vectors.

After inserting the foreign DNA, the host organisms produces several proteins which do not belong to their point of origin. Due to the expression of these proteins, recombinant-DNA technology has been used.

Therefore, the most common proteins produced by transgenic organisms are albumin, fibrinogen, and human antithrombin.

The window of opportunity is called Critical period.

During pregnancy, every part of the baby's body forms at a certain point. During this time, the body can be very sensitive to damage caused by drugs, alcohol, or other harmful stresses.

All pregnancies have a chance of starting with a birth defect. This is called  background risk. If an exposure increases the chance of a birth defect, that chance depends on which part of the body  is developing at the time of the exposure.

Once the body parts are formed, the risk of developing serious birth defects disappears. However, some exposures can affect the growth and function of some parts of the body.

Based on the information provided, the father does not have a case against the hospital based solely on the blood types of the twins.

Blood is a vital fluid that circulates through the human body, delivering essential nutrients, oxygen, hormones, and immune cells to various tissues and organs. Composed of a liquid component called plasma and cellular elements such as red blood cells, white blood cells, and platelets, blood performs several crucial functions. Red blood cells contain hemoglobin, a molecule that binds and transports oxygen, ensuring its distribution to cells throughout the body.

White blood cells play a crucial role in the immune system, defending against pathogens and foreign substances. Platelets aid in blood clotting, preventing excessive bleeding after injury. Blood also helps regulate body temperature and pH balance, carries waste products to organs responsible for elimination, and transports hormones and other signaling molecules. Its continuous circulation and constant replenishment maintain the overall health and functionality of the human body.

Explanation:

Answer: The molecules on the exterior of the cell will move inwards due to the difference in concentration

Explanation:

This happens because of Endosmosis, where the water molecules move from a region of higher concentration to a region of lower concentration through a semi-permeable membrane. Endosmosis is when the cell swells up due to a higher concentration in the exterior of the cell and a lower concentration in the interior of the cell.

Therefore, the water molecules move inside the cell until the concentrations of the exterior and the interior of the cell is balanced

Going by the diagrammatic illustration, the molecules would move into the cell until an equilibrium is reached.

Diffusion generally involves the movement of molecules from the region of higher concentration of a molecule to the region of lower concentration of the same molecule. The net movement will continue until both sides have equal concentrations of the molecule.

Looking at the diagram, there are more of the molecule outside the cell than inside of it. Thus, the molecules will keep moving inside the cell until both the outside and inside have the same concentration.

The magnitude of the electric field in the membrane is 8.75 x 10⁶ V/m.

The magnitude of the electric field in the membrane is 8.75 x 10⁶ V/m.

The given values are:

Thickness of the cell membrane = d = 8.0 x 10⁻⁹ m

Potential difference across the membrane = V = 0.070 V

The electric field E is given by the formula: E = V/d

The magnitude of the electric field in the membrane is 8.75 x 10⁶ V/m.

A cell membrane is made up of two layers of lipid molecules, which are arranged in a specific way that separates the inside and outside of the cell. The inner and outer surfaces of a cell membrane carry a negative and a positive charge, respectively. Because of these charges, a potential difference of about 0.070 V exists across the membrane.

The thickness of the cell membrane is 8.0×10⁻⁹ m. To determine the magnitude of the electric field in the membrane, we use the formula:

E = V/d

where E is the electric field, V is the potential difference, and d is the thickness of the membrane.

Substituting the given values, we get:

E = 0.070 V / 8.0×10⁻¹⁹ m E = 8.75 x 10⁶ V/m

Therefore, the magnitude of the electric field in the membrane is 8.75 x 10⁶ V/m.

Yes, specimens are visible on a phase contrast microscope because they refract the light that illuminates them.

Phase contrast microscopy is a technique used to enhance the contrast of transparent and colorless specimens that are difficult to visualize using brightfield microscopy. This is achieved by altering the phase of light that passes through the specimen, which results in the refraction of light waves.

Refraction causes the light waves to bend as they pass through the specimen, and this bending creates an interference pattern that can be visualized using a specialized objective lens. The interference pattern is then interpreted as an image of the specimen.

In summary, phase contrast microscopy relies on the refraction of light by specimens to visualize them. This technique is particularly useful for studying live cells and other transparent biological specimens.

During DNA replication, the organism that would have the fewest origins of replication per cell is the human fruit fly. The correct option is c.

What is DNA replication?

DNA replication is the process in which an organism's DNA makes a copy of itself, resulting in two identical sets of genetic material. The DNA replication process is essential for cell division and growth, as well as for the transfer of genetic material from one generation to the next. DNA replication is the fundamental process by which organisms pass their genetic information to their offspring.

Organisms that have fewer origins of replication per cell are more likely to have a slower cell division rate. Because more origins of replication produce more replication forks, more replication forks mean a quicker replication process, and more origins of replication imply a faster cell division rate, which is not always feasible. DNA replication in organisms is influenced by a variety of factors, including the cell cycle stage, the replication origin's complexity, and the DNA's structure.

Hence, the correct option is c.
