Enzymes hasten chemical reactions by lowering their activation energy. They do this by forming a unique complex with the substrate in a 'lock and key' manner. This complex helps to break the bonds of the substrate more quickly, effectively catalyzing the reaction.
Explanation:Enzymes catalyze chemical reactions by reducing the activation energy needed for the reaction to occur. They achieve this through a mechanism called 'enzyme-substrate complex.' An enzyme has an active site which is a unique and specific shape, where the reactant, known as the substrate, fits like a lock and key. When the substrate binds to the enzyme's active site, it forms an enzyme-substrate complex. This complex helps to break the reactants’ bonds, therefore transforming the substrate into a product at a faster rate than it would have without the enzyme. Some enzymes might also go through a process called induced fit, where the enzyme changes shape slightly to better accommodate the substrate.

Cyclones are formed due to
mist and snow
clouds and fog
warming of oceans
underwater earthquakes
Answer:
Correct answer is warming of oceans
Explanation:
when hot moist air flows at the upper surface of the ocean it tries to move in upward direction due to which less amount of air is left at the surface of ocean and hence a lower air pressure is created in this area.
surrounding air which is at higher air pressure try to push the low pressure air which rises the temperature of low pressure air and again this air moves upward leaving behind less air at the surface of the ocean.
when this high temperature and moist air moves in the upward direction it temperature decreases due to which clouds are formed . This combination of clouds and wind continuously grows and started spinning. When this combination of wind and clouds spin fast, that time an eye is formed at the center. At this center very low air pressure is there and air with high pressure flows down into this center.
In this way cyclones are formed.
Can mitochondria or chloroplasts where does oxygen gas production happen
Oxygen production occurs in chloroplasts during photosynthesis, a process that converts sunlight into energy. Mitochondria, on the other hand, consume oxygen for cellular respiration to produce ATP, the cell's main energy molecule.
Explanation:The production of oxygen takes place in chloroplasts, not in mitochondria. Chloroplasts are where photosynthesis happens in plant cells. Photosynthesis is a process that converts sunlight into energy, with oxygen being a byproduct of this process which is then released into the atmosphere.
On the other hand, mitochondria, often called the 'powerhouses' of the cell, utilize oxygen for a process known as oxidative phosphorylation. This is part of cellular respiration, a process that converts glucose and other nutrients into ATP (adenosine triphosphate), the cell's main energy-carrying molecule.
During this process, oxygen gets used and carbon dioxide is produced as a waste product.

(a) compare interstitial and vacancy atomic mechanisms for diffusion. (b) cite two reasons why interstitial diffusion is normally more rapid than vacancy diffusion.
Interstitial and vacancy are two different diffusion mechanisms, with the former being typically faster due to the lighter mass of the diffusing species and the greater availability of interstitial sites for movement.
Explanation:(a) When comparing interstitial and vacancy diffusion mechanisms, the primary difference is in how atoms or molecules move from one location to another within a material. Interstitial diffusion occurs when the diffusing atoms or molecules move through the empty interstices in the crystal lattice. Conversely, vacancy diffusion requires a vacant lattice site or 'hole' to be near an atom; the atom can then jump into this void, leaving behind a new vacancy.
(b) There are two main reasons why interstitial diffusion is normally more rapid than vacancy diffusion. First, the mass of the diffusing species in interstitial diffusion tend to be lighter, allowing them to move faster. Second, interstitial sites are typically more available and require less activation energy to move into, compared to the energy required for an atom to leave its place and form a vacancy.

Answer: Constructing dams, Building desalination plants.
A drought is a natural disaster that occur in a region that receives very low precipitation. The region exhibit desert like conditions such as hot and dry climate, compact and infertile soil, and scanty available water resources. Constructing dams can preserve the available water resource, it will also help in preserving the surrounding soil in maintaining the moisture content. If the available water is saline. Then the salinity can be removed by the desalination process and the water can be used.
What do chloroplasts look like under a microscope?
I depends, though “small greenish blob” would be a good description. The other answers contain great pictures of plant chloroplasts under a decent quality light microscope. However, plants (and algae) don’t all have the same size of chloroplasts and the chloroplasts can be very hard to see when they are small, not just because of size, be also because they appear less green (small size = less light absorption = less green in color).
If you use fluorescence microscopy, then the chloroplasts glow reddish-orange in color (very cool, especially when you have swimming algae).

After having harvested a wild turkey, what is the best and safest way to carry it out of the woods?
In order to carry the harvested turkey out of the woods, the hunter is always recommended to keep the bird in the hunter orange bag or cover it under the camouflage hunting vest.
Further Explanation:
The hunting of the turkeys is a very popular hunting program in many states. It is also posed as a dangerous activity as many turkey hunters have accidentally been shot during the hunting programs. The prime cause of this is the inability of the hunters to identify their target prior to shooting. This is because while turkey hunting the hunters are dressed in camouflaged dresses in order to hide and not recognized by the turkey and also to attract them. But in a way, the hunters also attract the other hunters who can recognize these hunters as the turkeys. Therefore, it is always suggested to never wear blue, black or white-colored vests as these colors match the feather of the turkeys.
Once a turkey is harvested, a hunter should be very careful while carrying it out of the woods. The bird must be concealed in an orange bag or hid under the camouflaged vest. The wings of the birds should not be hanging and the head must be covered entirely so as to not be displayed as a live bird by other hunters. The blaze orange garment is supposed to be worn by the hunters while traveling between the hunting sites in order to be identified by other hunters.

What is moving a limb away from the midline of the body along the frontal plane called?
Abduction is the act of moving a limb away from the midline of the body along the frontal plane. This can be as simple as raising the arm or spreading fingers apart. The opposite movement, bringing the limb towards the body, is called adduction.
Explanation:The action of moving a limb away from the midline of the body along the frontal plane is called abduction. These motions occur within the coronal plane and involve medial-lateral movements. For example, when you raise your arm at the shoulder joint, moving it laterally away from the body, it is considered as abduction. Similarly, spreading the fingers or toes apart is also an example of abduction. Conversely, adduction is the movement that brings the limb towards the body or across the midline. The movements of abduction and adduction take place at joints like the shoulder, hip, wrist, metacarpophalangeal, and metatarsophalangeal.

Which is an example of the electromagnetic force?
An example of the electromagnetic force is static electricity, which is a part of the unified electrical and magnetic forces. It plays a vital role in molecular bonding and everyday forces such as friction and tension.
Explanation:An example of the electromagnetic force is static electricity. This force is essential in many aspects of science, including chemical and biological sciences where it facilitates ionic and hydrogen bonding. The electromagnetic force is also crucial in daily experiences such as friction and the normal force.
When we consider two charged particles interacting, this force is known as the Coulomb force. Moreover, electromagnetic interactions are responsible for friction, tension, and effectively, all macroscopic forces we experience, excluding gravity.
The unification of electrical and magnetic forces into the electromagnetic force was a significant scientific breakthrough, which showed that these forces, previously thought separate, are manifestations of the same fundamental force in nature.
Final answer:
An example of the electromagnetic force is static electricity, as well as the forces of friction and the normal force. It is a fundamental force of nature that can be attractive or repulsive and is much stronger than gravity on the atomic scale.
Explanation:
An example of the electromagnetic force is static electricity. This force, which includes the interaction of charged particles and the magnetic forces affecting objects like a compass needle, is one of the four fundamental forces of nature, and is responsible for various phenomena such as ionic bonding and hydrogen bonding in chemistry, as well as the familiar forces of friction and the normal force in physics. The electromagnetic force is an inverse square law force, meaning its strength decreases with the square of the distance between the interacting particles, and it can be either attractive or repulsive.
While gravity, another fundamental force, may seem strong, the electromagnetic force is substantially more powerful at the scale of atoms and molecules. It is the force that holds atoms together, governs the interaction between our feet and a bathroom scale, and is behind the sensation of touch. Notably, it is the net external electromagnetic force that is relevant, as these forces nearly cancel out in macroscopic objects, preventing them from overwhelming gravitational forces.

A large group of islands which are scattered closely in the body of water is called archipelago. The water body is usually oceans but it can be river and lakes. Volcano eruption is one of the main causes of making most of the island in an archipelago and these islands are called oceanic islands.
One of the example of archipelago is Finland’s Archipelago Sea which has more than 50,000 islands although many of them are so small that they do not measure even one acre. Therefore the statement is true.
The process by which a soil nutrient is reduced and released to atmosphere as a gas
The question refers to the nitrogen cycle, particularly the process of denitrification. In this process various soil bacteria convert ammonia to nitrogen gases, which are then released into the atmosphere. Human activities can significantly influence this cycle, potentially leading to ecological issues.
Explanation:The process by which a soil nutrient is reduced and released to the atmosphere as a gas refers to the nitrogen cycle, specifically the denitrification step. It begins with the ammonification process in which ammonia is released during the decomposition of nitrogen-containing organic compounds. Then, there is the nitrification process where soil bacteria transform ammonia into nitrite then to nitrate. This culminates in denitrification, where other soil bacteria reduce nitrates into nitrogen gases such as N₂O, NO, and N₂ which are then released into the atmosphere.
Human activities like fossil fuel combustion and use of artificial fertilizers can contribute significantly to these processes. The release of nitrogen into the environment can cause several ecological problems including climate change due to nitrous oxide, a potent greenhouse gas.
