Why does an octopus have 9 brains? Octopuses have 3 hearts, because two pump blood to the gills and a larger heart circulates blood to the rest of the body. Octopuses have 9 brains because, in addition to the central brain, each of 8 arms has a mini-brain that allows it to act independently. Do […]
What drives most of the activity on the surface of the sun?
What drives most of the activity on the surface of the sun? The Sun’s gases are constantly moving, which tangles, stretches and twists the magnetic fields. This motion creates a lot of activity on the Sun’s surface, called solar activity. Does the sun contribute to global warming? No. The Sun can influence the Earth’s climate, […]
How do you avoid collision in unity?
How do you avoid collision in unity? 3 Replies. Create a new layer called “Enemies” and have it be the layer of all your enemy gameobjects. Then take a look at the Physics Layers settings under Edit/Project Settings/Physics, and disable collisions for objects in the Enemies layer with other objects in that same layer. Is […]

What is an example of uniform acceleration?
What is an example of uniform acceleration? Uniform Acceleration Equations One direction is considered to be positive and another one as negative. One of the common examples of uniformly accelerated motion is freely falling bodies. The only acceleration which is acting on the body is g (acceleration due to gravity). Can a body have a […]
What is the radius of 1st orbit of Li2+?
What is the radius of 1st orbit of Li2+? Complete answer: He+, Li2+ and Be3+contain one electron like hydrogen, so they are called H-like particles. Radius of the first orbit of the hydrogen atom is called Bohr’s radius, i.e. ao=52.9pm. What is the value of radius of Bohr’s orbit? The CODATA value of the Bohr […]
What is a bar graph explain with an example?
What is a bar graph explain with an example? A bar graph can be defined as a chart or a graphical representation of data, quantities or numbers using bars or strips. Bar graphs are used to compare and contrast numbers, frequencies or other measures of distinct categories of data. How do you describe the trend […]
What are the 5 Rules of minerals?
What are the 5 Rules of minerals? Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level. Color and density are determined primarily by the chemical composition. What are the […]
How do you fix low minute ventilation?
How do you fix low minute ventilation? Auto-PEEP is easily corrected by disconnecting the tube from the bag (or vent) and pressing on the chest (pushing air out and suspending ventilation for 30–60 seconds); blood pressure and pulse oximetry will improve quickly. What is a normal minute ventilation? Normal minute ventilation is between 5 and […]
How can you say that one substance is different from another?
How can you say that one substance is different from another? Different substances have different properties; density is one property that can be used to tell two substances apart. Density is a property that does not depend on the shape or size of an object. In which state of matter are molecules moving the fastest? […]
