The correct option is B ; All of these animals are arthropods , Arthropods (/rrpd/, from Ancient Greek o (arthron) 'joint' and (pous) 'foot' (gen. )) are invertebrates with an exoskeleton, segmented bodies, and paired jointed appendages.

Arthropods are classified as members of the phylum Arthropoda. They are distinguished by their jointed limbs and chitin cuticle, which is frequently mineralised with calcium carbonate. The arthropod body plan is made up of segments, each with two appendages.

Arthropods have an external skeleton and are bilaterally symmetrical. To continue growing, they must go through moulting stages, in which they shed their exoskeleton to reveal a new one. Some animals have wings. They are a hugely diverse group, with up to ten million different species.

In the adult organism, mitosis plays a role in cell replacement, wound healing and tumour formation. Mitosis, although a continuous process, is conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase and telophase.

Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA.

After the collision, the smaller object moves east at 0.800 m/s.

The question provides information about a collision between a 4.00-kg object moving east at 2.00 m/s and a 6.00-kg object initially at rest. After the collision, the larger object moves east at 0.800 m/s.

To determine the final velocity of the smaller object, we can use the principle of conservation of momentum. According to this principle, the total momentum before the collision is equal to the total momentum after the collision.

The momentum of an object is given by the product of its mass and velocity.

Before the collision, the total momentum is (4.00 kg) * (2.00 m/s) = 8.00 kg⋅m/s.

After the collision, the larger object moves east at 0.800 m/s.

To find the final velocity of the smaller object, we can subtract the momentum of the larger object from the total momentum and divide by the mass of the smaller object.

The momentum of the larger object is (6.00 kg) * (0.800 m/s) = 4.80 kg⋅m/s.
The momentum of the smaller object can be calculated by subtracting the momentum of the larger object from the total momentum: 8.00 kg⋅m/s - 4.80 kg⋅m/s = 3.20 kg⋅m/s.

Finally, we can find the final velocity of the smaller object by dividing its momentum by its mass: (3.20 kg⋅m/s) / (4.00 kg) = 0.800 m/s.

Therefore, after the collision, the smaller object moves east at 0.800 m/s.

Answer:

Explanation:

During the evolutionary refinements from fish to mammals, a shift from gills to lungs was necessary because **protecting gas-exchange surfaces from drying out is difficult when on land**.

Gills are specialized respiratory structures in aquatic organisms that extract oxygen from water. They are highly efficient in extracting oxygen from water, but they are not suitable for life on land. When an organism transitions from an aquatic environment to a terrestrial one, it faces the challenge of preventing the delicate respiratory surfaces from drying out.

On land, the availability of water is limited, and the atmosphere is generally drier compared to aquatic environments. Gills, being adapted for extracting oxygen from water, are not effective in preventing dehydration and can easily dry out in the air. This would impair their function and compromise the organism's ability to respire efficiently.

Lungs, on the other hand, are respiratory organs that have evolved in terrestrial organisms, including mammals. Lungs are more suitable for breathing in air because they have internal structures that help retain moisture and prevent excessive drying. They are better adapted to extract oxygen from the air while minimizing water loss and protecting the gas-exchange surfaces from desiccation.

In summary, the shift from gills to lungs was necessary during the evolutionary transition from fish to mammals because protecting gas-exchange surfaces from drying out is difficult when on land. Lungs provided a more efficient and adaptive respiratory system for survival in terrestrial environments.

Naphthalene poses hazards of respiratory irritation, skin and eye irritation, and toxicity if ingested. After the experiment, dispose of the test tube and its contents as hazardous waste according to local regulations.

Naphthalene is a white solid aromatic hydrocarbon commonly used as a moth repellent. Its Material Safety Data Sheet (MSDS) typically highlights the following safety hazards:

1. Inhalation: Naphthalene can be harmful if inhaled, causing respiratory irritation, dizziness, nausea, and headache.

2. Skin Contact: Direct contact may lead to skin irritation, redness, and potential allergic reactions.

3. Eye Contact: Naphthalene can cause eye irritation, redness, and discomfort.

4. Ingestion: Swallowing naphthalene can be toxic, leading to abdominal pain, nausea, vomiting, and potential damage to internal organs.

After completing an experiment involving naphthalene, it is important to dispose of the test tube and its contents properly. Naphthalene should be collected and disposed of in accordance with local regulations for hazardous waste. It should be placed in a designated waste container or taken to an appropriate waste disposal facility for safe handling and disposal. Proper precautions should be taken to prevent further exposure or environmental contamination. Always consult the manufacturer's instructions and local regulations for specific disposal guidelines.

A tornado most commonly forms from a mass of cold, dry air overlaps a mass of warm, moist air, which gives rise to large storm clouds.

Tornadoes are typically continental phenomena, their formation occurs through the arrival of cold fronts in regions where the air is warmer and more unstable, favoring the development of a storm, which, in turn, drives the formation of this type of cyclone.

In this case,these movements are formed by currents of hot and cold air that meet, creating a rotating area of ​​pressure.

Most frequently, a tornado develops when a mass of cold, dry air crosses over a quantity of warm, moist air, creating huge storm clouds in the process.

The creation of a storm, which in turn promotes the development of a tornado, is what causes tornadoes, which are primarily continental phenomena, to originate. This happens when cold fronts move into areas where the air is warmer and more unstable.

These movements in this instance are caused by the convergence of hot and cold air currents, which results in a spinning area of pressure.

Air follows a branching pattern in the respiratory system, starting with larger tubes like the trachea and bronchi, and moving into smaller bronchioles before reaching the alveoli for gas exchange. This structure optimizes oxygen uptake and carbon dioxide release.

The respiratory system is responsible for the exchange of oxygen and carbon dioxide between the body and the environment.

The pathway of air in the lungs closely resembles the path of blood in the circulatory system, as it follows a branching pattern to maximize surface area for efficient gas exchange.

Air enters the respiratory system through the nasal passages or mouth and then travels through the pharynx and larynx. From there, it enters the trachea, a large tube reinforced with cartilage rings, which divides into two smaller tubes called the bronchi.

The bronchi further branch into smaller bronchioles, which continue to divide into even smaller respiratory bronchioles.

The respiratory bronchioles eventually lead to the alveoli, which are tiny air sacs surrounded by a network of capillaries. It is within the alveoli that the actual gas exchange takes place.

Oxygen from the inhaled air diffuses across the thin alveolar walls and enters the bloodstream, while carbon dioxide, a waste product, moves in the opposite direction to be exhaled.

This extensive branching of the airways in the lungs ensures that air reaches the alveoli, maximizing the surface area available for gas exchange.

The structure of the respiratory system optimizes the exchange of gases, providing the body with the oxygen it needs while eliminating carbon dioxide waste.
