Describe a horse walks along a straight path it travels 3 m in one second 4 m in the next second and 5 m in the third second des

cribe the horse motion
Biology
1 answer:
trasher [3.6K]3 years ago
7 0

Answer: The motion is accelerated.


Step-by-step explanation: Given that the horse is walking along a straight line.

The horse travels 3 m in first second, so its speed is 3m/s.

In the next second, the horse travels 4 m, so its speed is 4 m/s.

In the third second, the horse travels 5 m, so its speed is 5 m/s.

Since the speed of the horse is increasing per second i.e., the speed in not constant, so the motion of the horse is accelerated.

Does the water cycle, the nitrogen cycle, and the carbon-oxygen cycle play a role in ecosystem balance? Explain.
Anika [276]

Explanation: The water cycle is also known as the hydrological cycle. It describes how water moves on, above, or just below the surface of our planet. Water molecules move between various locations - such as rivers, oceans and the atmosphere - by specific processes. Water can change state. Nitrogen compounds found in cells include proteins. Nitrogen from the air is converted into soluble ions that plant roots can absorb. It forms part of nitrogen compounds in the plants, and is then passed from one organism to the next. It is returned to the atmosphere as nitrogen gas. This is the nitrogen cycle. The carbon-oxygen cycle is the process by which plants use carbon dioxide for respiration during photosynthesis and produce oxygen. During this process, carbon dioxide becomes part of the plant, and when the plant dies in a carbon-rich state it is possible for it to become a fossil fuel.

Explain the relationship between mutations, adaptations, natural selection, and extinction
Musya8 [376]

Mutations and natural selection cause adaptations. Mutations can cause instant adaptations, while natural selection is the process by which adaptations occurs over a series of generations.  

Adaptations are changes or processes of changes by which an organism or species becomes better suited for its environment.  

A mutation is an alteration of the DNA sequence. Sometimes such alterations code for the same amino acid sequence as the unaltered DNA strand during protein synthesis. In such a circumstance, the mutation is not detectable. However, other mutations alter the genetic code in such a way that a noticeable change in the trait that is associated with that gene is visible. Sometimes such mutations are advantageous and improve the organism's ability to survive in its environment.  

Natural selection is the process by which organisms with more advantageous traits (being camouflaged, being covered with the correct outer covering for the temperatures of that environment, stronger/ larger/ or faster to fight off or run from predators, etc.) are more likely to survive in a particular environment. Likewise, organisms less advantageous traits are more likely to die due to the pressures exerted by the environment (such as temperature, predators, illness, etc.). Therefore, the organisms with the advantageous traits that survive are more likely to survive to find a mate and reproduce. Thus, the advantageous traits are passed down to future generations.
