In food web, the relationship between Texas horned lizards and other lizards would be described as competitive, as they are both predators and compete for similar prey. The term "mutualistic" would not accurately describe their relationship in this scenario.

A food web comprises of all the well established pecking orders in a solitary biological system. In an ecosystem, every living thing is connected to multiple food chains. Every pecking order is one potential way that energy and supplements might take as they travel through the biological system.

A food web is the mix of all the pecking orders in a biological system. We might observe something like a mouse eating a plant and then being eaten by an owl in a typical food chain.

Answer:

The part of a microscope that holds the slide is called the stage.

Explanation:

The stage is typically a flat, rectangular platform that is located below the objective lenses and above the base of the microscope. The slide is placed on the stage and secured in place using clips or other mechanisms. The stage can be moved horizontally and vertically using stage controls, which allows the user to position the slide in the field of view of the objective lenses. Some microscopes also have a mechanical stage, which allows the user to move the stage with greater precision using a pair of knobs or a joystick.

Answer:

STAGE CLIPS

Explanation:

The stage is the region of the microscope where the slide is placed. It is a flat surface on which slides are displayed. The slides are thin glass sheets used for holding items examined under a microscope. The slides are held in place by stage clips.

This information, along with the discovery that rocks along the mid-Atlantic ridge were younger, was evidence for Seafloor spreading.

What is seafloor spreading?

Seafloor spreading is the hypothesis that the ocean's crust develops along the mid-ocean ridge system's undersea mountain zones and spreads out laterally away from them. The theory of plate tectonics, which revolutionised geologic thought throughout the final quarter of the 20th century, was developed in large part as a result of this concept.

When the seafloor spreads, tectonic plates, which are huge portions of the Earth's lithosphere, split apart from one another. Seafloor spreading and other tectonic activity processes are caused by mantle convection. Mantle convection is the term for the mantle's slow, turbulent circulation.

Hence the correct option is B; seafloor spreading.

The process of Glycolysis is a catabolic process  in which two molecules glucose goes through a ten- step pathway and yield two molecules of pyruvate . It is a major part of carbohydrate metabolism .

Mechanism Of Glycolysis

The glycolysis is also known as EMP pathway and it is involved in both aerobic and anaerobic conditions .There are two phases in the mechanism of glycolysis in which 5 reactions takes place in each phase and the process of glycolysis takes place in cytosol

Preparatory phase refers to the  generation of two molecules of  glyceraldehyde 3-phosphate from one molecule of glucose which further goes into the payoff phase . In this phase two molecules of ATP are used and two regulatory enzymes were involved in this reaction .

Payoff phase refers to the further break down of two molecules of glyceraldehyde3-phosphate to two molecules of pyruvate . In this phase four molecules of ATP and two molecules of NADH are generated . In this phase only one regulatory enzyme is involved which is the breakdown of PEP to pyruvate  .

Both the phases of glycolysis takes place in the cytoplasm and there are  three enzymes that involved in regulating the glycolytic pathway .This process is also known as the catabolic process .

The subcutaneous layer (also known as the hypodermis or superficial fascia) was injured if fat/adipose tissue is observed from a cut on the arm. (Option 2)

If fat/adipose tissue is observed from a cut on the arm, it is likely that the injury has affected the subcutaneous layer. The subcutaneous layer is located below the dermis and consists of adipose tissue and connective tissue.

The subcutaneous layer lies beneath the dermis and is composed of adipose (fat) tissue and connective tissue. It serves as a layer of insulation, energy storage, and padding. If fat/adipose tissue is observed from a cut on the arm, it indicates that the cut has penetrated through the skin layers (epidermis and dermis) and into the subcutaneous layer.

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.

Fragmentation is a form of asexual reproduction and is seen in annelids, fungi, cyanobacteria, sponges, and flatworms.

In Fragmentation, an organism divides itself into a number of fragments. It occurs when an organism completely breaks down independently irrespective of the other parts. Each one of these fragments matures into fully grown adults that are clones of the original organism.

Asexual reproduction usually involves the participation of a single parent alone can produce new offspring. The newly produced individual is genetically identical to one another and its parent. Both multicellular and unicellular organisms divide by fragmentation which is asexual reproduction.

Fragmentation is the most common method of reproduction in lower invertebrates. It is seen in many organisms including filamentous cyanobacteria, algae, lichens, molds, many plants, and animals such as flatworms,  annelid worms, sponges, and sea stars.

The organisms that can reproduce by fragmentation are Option d Sponges and Sea anemones.

Fragmentation is a form of asexual reproduction in which an organism breaks into two or more fragments, and each fragment develops into a new individual. Both sponges and sea anemones are examples of organisms that exhibit this mode of reproduction.

Sponges are simple multicellular animals that lack true tissues and organs. They possess a porous body structure, and when a sponge is fragmented, each fragment has the potential to develop into a new sponge through regeneration. These fragments contain specialized cells called archaeocytes that can differentiate into various cell types required for the formation of a new sponge.

Sea anemones, on the other hand, are marine animals belonging to the phylum Cnidaria. They have a cylindrical body with tentacles surrounding their mouth. When a sea anemone is fragmented, each piece can regenerate into a complete individual. The process involves the differentiation of cells within the fragments, leading to the development of new tentacles, body parts, and eventually a mature sea anemone.

Both sponges and sea anemones have remarkable regenerative abilities, allowing them to reproduce through fragmentation. This form of asexual reproduction enables them to colonize new areas, expand their population, and adapt to changing environmental conditions. Therefore the correct option is D

Growing a potato crop with few variations can lead to genetic homogeneity, which means that all the plants have very similar genetic makeup.

This lack of genetic diversity can make the crop more susceptible to diseases, pests, and environmental stresses, such as drought or extreme temperatures. If a disease or pest infestation targets the specific genetic makeup of the crop, it can quickly spread and wipe out the entire crop.

In contrast, if there is genetic variation within the crop, some individuals may have genetic traits that make them resistant to the disease or pest, allowing them to survive and reproduce. This genetic diversity helps to maintain the health and resilience of the crop, and increases the likelihood that some individuals will survive and pass on their beneficial traits to future generations.
