Enzymes that cleave nucleotides from the ends of a DNA molecule are known as Restriction endonucleases.

Enzymes may be defined as the type of biocatalysts that significantly increase the rate of a chemical reaction without being changed in the overall process. It is thought that all cellular reactions and processes are mediated by enzymes.

Restriction endonucleases are the enzymes that are also called molecular scissors which are responsible for cutting DNA at specific sites. These enzymes are present in bacteria in order to provide a defense mechanism called the restriction modification system.

There are various types of restriction enzymes are known. For example, BamH1, EcoRI, Hind III, etc.

Therefore, restriction endonucleases are the enzymes that cleave nucleotides from the ends of a DNA molecule.

Answer:

1)•Plants do not have a circulatory system.

•Humans have a well defined circulatory system.

2)•transportation in plants occurs through specialised tissue xylem and phloem.

•Transportation in humans occurs through a netwotk of blood vessels such as artery vein capillary.

3)In plants substances transported are water, minerals, sugars and amino acid.

•In humans substances transported are glucose, glycerol, minerals, vitamins, fatty acids, amino acids and hormones.

4)Transportation in plants in controlled by opening and closing of stomata.

•Transportation in humans is controlled by constriction or dilation of blood bessels.

-->■Transportation in humans is more effective than the plants because in humans there is a well defined circulatory system which is highly regulated.As transport occur through blood vessel , transportation can be regulated by dilation or constriction of blood vessel.But plant do not have such circulatory system.

Explanation:

I took the quiz(-.-)

Rotifers foot is transformed into a variety of structure for moving and swimming and attach itself to a different structure, hence option d is correct.

Some rotifers are really planktonic and free-swimming, while others travel around a substrate via inchworming, and some are sessile and reside inside tubes or gelatinous holdfasts.

About 25 species are sessile or planktonic, colonial (such as Sinantherina semibullata), and some rotifer species have evolved four moveable toes that are equipped with pedal glands to facilitate swimming and crawling.

Rotifers swiftly colonize new environments and transform primary production (algae and cyanobacteria) into a form that is secondary consumers.

Therefore foot of the rotifers is changed into a different structure for movement is attach itself to a variety of structures, hence option d is correct.

Answer:

Until the past decade, scientists, research institutions, and government agencies relied solely on a system of self-regulation based on shared ethical principles and generally accepted research practices to ensure integrity in the research process. Among the very basic principles that guide scientists, as well as many other scholars, are those expressed as respect for the integrity of knowledge, collegiality, honesty, objectivity, and openness. These principles are at work in the fundamental elements of the scientific method, such as formulating a hypothesis, designing an experiment to test the hypothesis, and collecting and interpreting data. In addition, more particular principles characteristic of specific scientific disciplines influence the methods of observation; the acquisition, storage, management, and sharing of data; the communication of scientific knowledge and information; and the training of younger scientists.1 How these principles are applied varies considerably among the several scientific disciplines, different research organizations, and individual investigators.

If lacO were mutated, what effect would this have on lactose metabolism? The repressor would not properly bind to the operator, and the lac operon would be over expressed. How does the cell recognize that lactose needs to be metabolized? Lactose is converted into allolactose, which inhibits the lac repressor.

Explanation:

Have you ever wondered what would happen if Earth lost its atmosphere? It's believed that the planet is slowly losing its atmosphere, bit by bit, as it bleeds off into space. But what if Earth instantly lost its atmosphere, all at once? Just how bad would it be? Would people die? Would everything die? Could the planet recover?

What Would Happen?

Here's a breakdown of what could be expected:

It would be silent. Sound requires a medium to transmit waves. You could feel vibrations from the ground, but you wouldn't hear anything.

Birds and planes would fall from the sky. Although we can't see air (except clouds), it has mass that supports flying objects.

The sky would turn black. It's blue because of the atmosphere. You know those pictures taken from the Moon? The Earth's sky would look like that.

All unprotected plant and animal life on the Earth's surface would die. We can't survive long in a vacuum, which is what we'd have if the atmosphere suddenly vanished. It would be much like being "spaced' or shot out of an airlock, except the initial temperature would be higher. Eardrums would pop. Saliva would boil. But you wouldn't die instantly. If you held your breath, your lungs would pop, which would be the quickest (albeit most painful) death. If you exhaled, you'd pass out in about 15 seconds and die in around three minutes. Even if you were handed an oxygen mask, you wouldn't be able to breathe. This is because your diaphragm uses the pressure difference between the air inside your lungs and outside your body to inhale.

Let's say you have a pressure suit and air. You'd live, but you'd get a massive sunburn on exposed skin because the Earth's atmosphere is what filters solar radiation. It's hard to say how much trouble you'd be in from this effect on the dark side of the planet, but being in direct sunlight would be severe.

The rivers, lakes, and oceans would boil. Boiling occurs whenever vapor pressure of a liquid exceeds external pressure. In a vacuum, water readily boils, even if the temperature is warm. You can test this yourself.

Although water would boil, the water vapor would not fully replenish the atmospheric pressure. An equilibrium point would be reached where there would be enough water vapor to prevent the oceans from boiling off. The remaining water would freeze.

Eventually (long after surface life had died), solar radiation would break atmospheric water into oxygen, which would react with carbon on the Earth to form carbon dioxide. The air would still be too thin to breathe.

The lack of atmosphere would chill the Earth's surface. We're not talking absolute zero cold, but the temperature would drop below freezing. Water vapor from the oceans would act as a greenhouse gas, raising the temperature. Unfortunately, the increased temperature would allow more water to transition from the sea into the air, likely leading to a runaway greenhouse effect and making the planet more like Venus than Mars.

Explanation:

Organisms that need air to breathe would die. Plants and land animals would die. Fish would die. Most aquatic organisms would die. However, some bacteria could survive, so losing the atmosphere wouldn't kill all life on Earth. Chemosynthetic bacteria wouldn't even notice the loss of atmosphere.

Volcanoes and geothermal vents would continue to pump out carbon dioxide and other gases to add to the water. The most significant difference between the original and new atmosphere would be the much lower abundance of nitrogen. Earth could replenish some nitrogen from meteor strikes, but most of it would be lost forever.

Could Humans Survive?

There are two ways human beings could survive losing the atmosphere:

Build radiation-shielded domes on the Earth's surface. The domes would need a pressurized atmosphere and would need to support plant life. We would need time to build biodomes, but the result would not be much different from trying to survive on another planet. Water would remain, so there would be a source of oxygen.

Build a dome under the sea. The water could provide pressure and filter out some solar radiation. We wouldn't want to filter out all radiation because we'd probably want to grow plants (though maybe it would be possible to learn some tasty ways to prepare bacteria as food).

Answer:

Glucose

Explanation:

The brain is an energy-hungry organ. Despite comprising only 2 percent of the body’s weight, the brain gobbles up more than 20 percent of daily energy intake. Because the brain demands such high amounts of energy, the foods we consume greatly affect brain function, including everything from learning and memory to emotions.

Just like other cells in the body, brain cells use a form of sugar called glucose to fuel cellular activities. This energy comes from the foods we consume daily and is regularly delivered to brain cells (called neurons) through the blood.  

Studies suggest the quality of the foods consumed over a lifetime affects the structure and function of the brain. For instance, the consumption of omega-3 fatty acids found in fish provides structural material to maintain neurons. Studies also suggest omega-3 fatty acids are essential for the transmission of information between brain cells. In contrast, foods that are rich in sugars and saturated fats have been found to promote oxidative stress, which leads to damage to cell membranes.  

The food you eat also affects molecules in the brain that support cognition. Some foods, such as those with turmeric, support cognition by helping to maintain molecular events related to energy metabolism.

Recent studies suggest lifestyle choices that affect the metabolism of nerve cells, such as diet and exercise, may in some cases provide a non-invasive and effective strategy to counteract neurological and cognitive disorders.

b. Ovulation is the release of a mature ovum, which occurs once each month.

Explanation:is correct. post protected

Ovulation is the release of a mature ovum, which occurs once each month. The correct option is B.

The process of an egg being released from the ovary is called ovulation. The egg is released and travels down the fallopian tube, where it remains for 12 to 24 hours before being fertilised.

Although ovulation is necessary for conception, more than simply an egg is required. For instance, there needs to be a clear path to the egg. A blocked fallopian tube prevents pregnancy from happening.

Around the time of ovulation, you could notice that your cervical mucus is wetter, clearer, and more slippery. After ovulation, there is a slight increase in body temperature that you might be able to measure with a thermometer.

Thus, the correct option is B.

Both desert and tundra plants grow and flower quickly in the short growing season.

Desert plants have special structures that allow them to trap and store water.

Tundra plants grow low to the ground to stay out of the cold and dry wind.

Plants in the desert and tundra both develop and bloom swiftly. Plants in the desert have unique that enable them to capture and store water. To avoid the cold, dry wind, tundra plants grow low to the earth.

Tundra is the coldest biome of all of them. The Finnish name for tundra is tunturi, which meaning treeless plain. It is well known for having landscapes that have been formed by frost, very cold temperatures, little precipitation, insufficient nutrients, and short growth seasons. A dead organic substance acts as a source of nutrients.

Tundra habitats, which are defined by their lack of plants and severe environments with minimal rainfall, are found in the Arctic and on mountain summits. The majority of the year, tundra areas are covered in snow, but the summer brings bursts of wildflowers.

Answer:

The enzyme denatured and changed shape

Explanation:

Enzymes are proteins, which can only function properly within a certain range of temperatures- when things get too hot, proteins undergo a structural change and are considered to be 'denatured'. This means that enzymes will not be able to function properly under those high temperatures, because the substrate bonding site would no longer be the right shape for said substrate.

The statement best explains the decrease in reaction rate is the enzyme denatured and changed shape. Thus option 3 is correct.

Enzymes are defined as a material that functions as a catalyst in living things, controlling the pace at which chemical processes take place without changing the substance itself.

There are six types of enzymes.
