Answer:

The three mechanisms of resistance crop are genetic resistance, tolerance, and avoidance. Genetic resistance is a trait that is naturally present in the crop, which makes it resistant to pests or diseases. Tolerance is the ability of the crop to tolerate pest or disease pressure without suffering major damage or yield loss. Lastly, avoidance is the ability of the crop to reduce the risk of pest or disease pressure by growing in a location or environment that is unfavorable to the pest or disease.

Answer:

The crane has a sharp and pointed beak adapted for catching and grasping prey. The sharp beak allows the crane to effectively stab and pierce its prey, such as fish, frogs, or small animals. The pointed shape helps the crane to accurately target its prey and secure a firm grip.

On the other hand, the duck has a flat beak, which is better suited for its specific feeding habits. Ducks are primarily filter feeders, and their flat beak enables them to sift through water or mud to collect small organisms, insects, and plants. The flat beak acts like a sieve, allowing the duck to strain out food particles while retaining water.

The difference in beak shape between the crane and the duck reflects their distinct feeding strategies and ecological roles. Each species has evolved its beak shape to optimize its ability to capture and consume the specific types of food sources available in their respective habitats.

Explanation:

The direct function of an action potential traveling down a skeletal muscle fiber is to allow for the myosin heads to cycle.

The correct answer is option B.

An action potential is an electrical signal that propagates along the membrane of a muscle fiber, triggering a series of events known as excitation-contraction coupling, which leads to muscle contraction. This process involves the interaction between the action potential, calcium ions, and the proteins within the muscle fiber.

When an action potential reaches the skeletal muscle fiber, it travels along the T-tubules, which are invaginations of the cell membrane that penetrate deep into the muscle fiber. These T-tubules are in close proximity to the sarcoplasmic reticulum (SR), a specialized network of tubules that stores calcium ions.

As the action potential reaches the T-tubules, it causes voltage-gated calcium channels on the SR to open. This allows calcium ions to flow out of the SR and into the muscle fiber's cytoplasm. The sudden increase in calcium concentration triggers the interaction between actin and myosin, the two proteins responsible for muscle contraction.

Calcium binds to the regulatory protein called troponin, which causes tropomyosin (not tropomyosin itself) to undergo a conformational change. This conformational change exposes the binding sites on actin, allowing the myosin heads to bind to actin and form cross-bridges.

Once the myosin heads are bound to actin, they undergo a series of cyclical interactions known as the cross-bridge cycle. This cycle involves the myosin heads pulling on the actin filaments, causing them to slide past each other and resulting in muscle contraction.

In summary, the primary function of an action potential traveling down a skeletal muscle fiber is to initiate the release of calcium ions from the sarcoplasmic reticulum. The presence of calcium allows for the interaction between actin and myosin, enabling the myosin heads to cycle and generate the force necessary for muscle contraction.

Type of mutation reverses the direction of parts of a chromosome is inversion. The correct answer is option C.

The chromosomes are thread like structures present in the nucleus and the  these chromosomes carry the genetic information in them from one generation to another.

Inversion inverts the structure of chromsome and it basically turns the chromsomes inverted.

Inversion is the process where one arm of the chromosome gets detached from the basic structure and it gets attached in the inverted direction.

This  creates multiple copies of DNA turning it into genetic material and one of the X linked recessive disorders is haemophilia in which same type of mutation caused by the chromosome at the 8th position takes place.

Answer: Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. This is usually due to the long time it takes for them to be replenished. Renewable resources are replenished naturally and over relatively short periods of time.

Explanation:

Explanation: Renewable resources can be replenished whenever you want, but non-renewable resources will keep dwindling down till there's nothing. For example, solar power is a renewable resource and will always be there because the sun will keep providing more solar power. Coal, on the other hand, is a non-renewable resource and won't always be there because coal takes a lot longer (300 million years) to form.

The structure that caused rotifers to be called wheel animals or wheel bearers is the corona.

Rotifers are also known as wheel animals or wheel bearers because of the corona structure around their mouth region.

Some rotifers are sessile and live inside tubes or gelatinous holdfasts that are attached to a substrate. Other rotifers migrate around a substrate through inch worming.

This is because when corona is seen in a sequential coordinated movement, it resembles the structure of a wheel, although it does not rotate in reality.

Therefore, we conclude that rotifers are called wheel animals or wheel bearers due to the presence of the corona structure.

Diffusion is the process by which gases move from an area of high pressure to low pressure. This is during internal and external respiration when gas is exchanged between the alveoli and lung capillaries. It is the simple movement of gases, without the need of any energy or endeavor by the body, between the alveoli and the capillaries in the lungs. Once in the lungs, the air travels over the bronchioles where it reaches the alveoli. From there, the oxygen from the air you breathe enters your blood in nearby blood vessels.

In single-celled organisms, diffusion across the cell membrane is enough for conveying oxygen to the cell. In order to be a beneficial means of providing oxygen to the cell, the rate of oxygen uptake must meet the rate of diffusion across the membrane.
