Speed is an expression of how fast an object moves. An object's speed is the rate of the total distance it travels in a certain amount of time. Units of speed include miles per hour (mph), centimeters per second (cm/sec or cm/s), meters per second (m/sec or m/s), or kilometers per hour (kph or km/hr)
The electromagnetic spectrum is made up of seven types of waves, they are: radio, microwave, infra red, visible lights, ultraviolet, X ray and gamma ray. The electromagnetic waves have both electric and magnetic properties and they can travel through vacuum. The waves have different properties and diverse uses.
The part of the electromagnetic spectrum that can penetrate all human skin and soft tissues is X RAY. X ray have short wavelength and it can penetrate soft tissues such as skin and muscles. Because of this property, it is typically used in the health care system to take X ray pictures of bones; the pictures help the health care providers in their diagnosis.
Answer:
Volcanic ash is formed during explosive volcanic eruptions when dissolved gases in magma expand and escape violently into the atmosphere
Explanation:
The force of the gasses shatters the magma and propels it into the atmosphere where it solidifies into fragments of volcanic rock and glass
Answer:
See the answer below
Explanation:
<em>The problem with grouping organisms together taxonomically based on their physical traits is that organisms that not genetically or evolutionally similar would be grouped together. Grouping would be based entirely on superficial similarities instead of combining different features such as genetics, nutrition, the complexity of bodies, etc.</em>
Based on physical traits, for example, all flying organisms will be grouped together. Birds, flying insects, bats, etc. would be grouped together, whereas, they are quite different from one another when it comes to the complexity of bodies and other features. Even though some insects have wings and can fly like birds, insects have exoskeletons and birds do not, the body of birds is more complex than that of insects, and evolutionally, birds are more advanced than insects.
Hence, grouping organisms based on their physical traits only would be too superficial and not reflect the true relationships between organisms.
Answer:
Suspect A
Explanation:
Suspect A should be called in for further questioning because the pattern of vascular bundles of plant materials from his/her shoe coincides with the arrangement pattern of vascular bundles in monocot plants.
In monocots, the vascular bundles are scattered within the ground tissues while in dicot, the vascular bundles are arranged in the form of a ring.
Since corn belongs to the monocot family, then its vascular bundles are scattered within the ground tissues. Hence, the suspect whose cross sections of the plant material from his/her shoes indicates the vascular arrangement belonging to a monocot will be called for further questioning.
<em>The correct answer is suspect A.</em>
