An astronaut weighs 760. N on Earth, what is his mass in kg?
What two gases in the atmosphere do animals and plants need to breathe and grow?
Answer: Explanation:
Plants and animals each produce the gases that the other needs to live. Plants need carbon dioxide—people and other animals exhale carbon dioxide as a waste product. People and other animals need oxygen—plants produce oxygen during an important process called photosynthesis, which turns the sun's energy into nutrients.
If an IPS student weighs 115 lbs on Earth, what is their weight in Newtons?
Answer:
511.545 Newtons
Explanation:
So 1 pound=4.44822 Newton’s so 115 times 4.44822 is 511.5453, then round it to get 511.545 Newtons.

Which of the following best describes the relationship between frequency and wavelength of electromagnetic waves?
A. If the frequency remains constant, the wavelength size increases.
B. As the wavelength size decreases, the frequency decreases.
C. As the frequency increases, the wavelength size decreases.
D. If the wavelength remains constant, the frequency increases.
Answer:
b makes the most sense
Explanation:
Answer:
I think C is the correct answer.
Explanation:
The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

Target games are a category of games where the participant propels an object, preferably with a high degree of accuracy, at a target.
Relate the buoyant force to increased depth
Answer:
The buoyant force is a result of pressure exerted by the fluid. The fluid pushes on all sides of an immersed object, but as pressure increases with depth, the push is stronger on the bottom surface of the object than in the top

What season is the Southern Hemisphere experiencing when the Northern Hemisphere is experiencing summer? Explain your answer.
The Southern Hemisphere experiences Winter during Northern Hemisphere's Summer. The reason why, is because the earth's axis is causing the North Pole to lean towards the sun.
It's the opposite in NH Winter and SH Summer. The South Pole is leaning towards the sun at this time.

A person who has the condition CIPA is unable to feel pain or temperature. Which sensory receptors are affected by this condition? (1 point)
A.) Chemoreceptors and photoreceptors
B.) Thermoreceptors and mechanoreceptors
C.) Mechanoreceptors and chemoreceptors
D.) Photoreceptors and thermoreceptors
Please help 15 Points
B........................
The person with CIPA condition that is congenital insensitivity to pain with anhidrosis will not pain and temperature and decreased sweating. Here, the thermoreceptor and mechanoreceptors are affected.
What is CIPA?CIPA is state known as congenital insensitivity to pain with anhidrosis is affecting the thermoreceptors and mechanoreceptors and thus make it unable to feel pain or temperature.
Receptors are structure able to capture signal from a stimuli and pass it to the brain from it carries a signal in return.
Mechanoreceptors are sensory receptors that transduce signals through ion channels which are mechanically gated. These receptors reacts to touch, pressure, motion stretching etc.
Thermoreceptors realize the change in temperature in the body and external stimuli with heat. If these two kind of receptors are damaged a person will be unable to feel pain or temperature.
Hence, a person with CIPA have affected with their Mechanoreceptors and thermoreceptors. Thus, option B is correct.

What process brings Carbon into the biotic part of an ecosystem?
Answer:
Carbon moves from plants to animals.
Explanation:
Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.
How Buoyancy force on an object is related to the weight of liquid it displaces?
The buoyancy force (B) is equal to the weight (W) of the fluid that a body in that fluid displaces. Fluid pressure increases with depth because of the (gravitational) weight of the fluid above. This increasing pressure applies a force on a submerged object that increases with depth. The result is buoyancy

Why do you use immersion oil with a 100X objective lens?
Answer:
For example, by placing a substance such as immersion oil with a refractive index that is equal to the glass slide in the space filled with air, more light is directed through the objective and a clearer image is observed
Explanation:
Hope you have a great day :)
The 100x lens is immersed in a drop of oil placed on the slide to eliminate any air gaps and loss of light due to refraction as light passes through glass(slide) → air → glass(objective lens)
What is Immersion oil?Oil immersion is a technique used to increase the resolving power of a microscope by immersing both the objective lens and the specimen in a transparent oil of high refractive index, resulting in an increase in the numerical aperture of the objective lens.
An immersion oil used in microscopy essentially consists of a solution of hydrogenated terphenyl, a polybutene, and a mineral oil, which provides a solution with a refractive index between 1.5100 and 1.5240.
It is used for the highest power objectives because light refraction from low power magnification microscope objective lenses such as (10X and 40X) is negligible and not noticeable.
Thus, the 100x lens is immersed in a drop of oil placed on the slide to eliminate any air gaps and loss of light due to refraction as light passes through glass(slide) → air → glass(objective lens).
