how is the structure of a caesium-134 atom different from the structure of an caesium-137 atom?
Answer:
Favorite Answer
Cs-134 has three fewer neutrons than Cs-137. Cs is element 55, meaning these isotopes have 79 and 82 neutrons, respectively.
P-32 has one more neutron than P-31. P-32 has 17 neutrons, and P-31 has 16.

Answer:
c. a ball rolling from point A to point B
Explanation:
a is talking about the position of the train
b is talking about the length of the track
d is talking about the distance a student is from somewhere.
So from taking all these options out we are left with C because the ball is actually moving and when something moves it is in motion.

Our brains, nerves, and spinal cords are made up of specialized cells that you don't find anywhere else in
the body.
True or false?
Answer:
TRUE
Explanation:
Central to the functioning of the nervous system is an extensive network of specialized cells called neurons, There are basically two major types of nerves: sensory and motor. Sensory nerves send information such as touch, temperature, and pain to the brain and spinal cord., Sensory neurons carry nerve impulses from tissues and organs to the spinal cord and brain. Motor neurons carry nerve impulses from the brain and spinal cord to muscles and glands(see Figure below). Interneurons carry nerve impulses back and forth between sensory and motor neurons.

What is brain?The brain, spinal cord, and a sophisticated nerve network are all parts of the nervous system. The brain and the body are communicated with via this system.
All bodily functions are managed by the brain. From the brain, the spinal cord descends via the back. It is made up of strands of nerves that branch out to every organ and area of the body.
The brain sends and receives messages via this network of nerves to many regions of the body.

Raj made the timeline below to show the progression of thinkers who developed theories about Earth's place in the universe. ? À Copernicus à Galileo à Newton Which thinker belongs at the beginning of Raj's timeline? Aristotle Kepler Ptolemy Thales
Answer:
Ptolemy
Explanation:
Ptolemy is the earliest earliest astronomer and mathematician in the list who lived and worked in the second century AD. Nothing is known about his personal life but his scientific work is well known.
He made his observations using naked eyes. In his opinion, the Universe is ''a set of nested, transparent spheres, with Earth in the center.''(Khan Academy). His argument was that the Moon, Mercury, Venus, and the Sun were all revolving around around Earth.
Although Ptolemy made significant contributions in Astronomy but he was wrong in positing that the earth did not move at all. This is inconsistent with our present day knowledge about the celestial bodies. Also, his work missed out other planets that were yet to be discovered then such as Uranus, Neptune, Pluto etc.
What evidence from geology, or the structure and history of planet Earth, influenced Darwin? *

Answer:
the evidence that influenced Darwin was the evidence indicating that volcanoes contribute to natural selection and evidence showing that rocks can change from one type to another after all he was a geologist and he saw various changes on the earth and it might've look a bit older than we thought

Your friend Olivia has a blemish on her shoulder that she can't easily see herself, so she asks you to check it out for her to help her decide if she should see her doctor. What are at least three things you would look for to help you advise her? (Remember: ABCDE!)
Answer:
Explanation:
There are a couple of things you can look for when analyzing your friend's blemish to determine whether she should see a doctor or not. Three of these signs are
Discoloration or texture on the blemish.The blemish is itchy or irritated.The blemish is bleeding
All three of these are signs that Olivia should see a doctor/dermatologist as soon as she can. This is because all of these point to skin cancer. A regular blemish is a single color and is imbedded within the skin. It does not appear textured or out of the skin, or even two or three different colors. Blemishes also are not itchy or bleed. Therefore, any of these signs would be a cause for concern.
4. In this investigation oxygen production was used to measure the light reaction. What are
two additional products that could be measured? What purpose do they serve in the light-
independent (dark) reaction?
Answer:
Photosynthesis is the process by which green plants absorb light energy from the sun with the assistance of water and carbon dioxide, and transform it into chemical energy to make (synthesize) carbohydrate (specifically glucose) and oxygen.
The "light-independent" or dark reactions happen in the stroma of the chloroplasts. This is also known as the Calvin Cycle. Since these processes can only happen in the chloroplast (a chlorophyll filled plastid in green plants), photosynthesis can only happen in green plants!
The first overall principle of photosynthesis is that the light energy from the sun is transformed into chemical energy and stored in the bonds of glucose (the sugar carbohydrate) for later use by the plant and/or organism that eats the plant.
The second overall principle of photosynthesis is that carbon, oxygen, and hydrogen atoms are taken from carbon dioxide and water molecules and are broken up and rearranged into new substances: carbohydrate (specifically glucose) and oxygen gas (so we can breathe, whew!). This reaction represents the transfer of matter: carbon dioxide from the atmosphere, water from the soil or atmosphere, into sugar in the plant and oxygen back into the atmosphere.
Light-Dependent Reactions
The first part of the process happens in the thylakoids of the chloroplasts and are the "light-dependent" reactions: The photosystems I and II absorb the photons from the sunlight and process them through the membranes of the thylakoids simultaneously. The photons excite electrons in the chlorphyll which then move through the electron transport chain and causes NADP- to combine with H+ forming NADPH. At the same time, ADP (adenosine diphosphate) has come from the dark reaction and a third phosphate chain is bonded forming ATP (adenosine triphosphate) to feed the Calvin Cycle next. Remember that ATP is the important source of all cellular energy.
We now believe that all the oxygen released in photosynthesis comes from the water molecules and all oxygen atoms that form the carbohydrates come from the carbon dioxide molecules. So, in other words during the light-dependent reaction a water molecule is broken down producing two H+ ions and half an oxygen molecule. We get the rest of the oxygen molecule when another water molecule is broken down.
Dark Reactions
Dark reactions are also known as the Calvin Cycle, the Calvin-Benson cycle, and light-independent reactions. The point is that they do not require sunlight to complete their process.
After ATP is formed in the first part of photosynthesis, for living things to grow, reproduce and repair themselves, the inorganic form of CO2 must be transformed into carbohydrate. This happens during the Calvin Cycle in the stroma (the fluid filled interior of the chloroplast). ATP and NADPH combine with CO2 and water to make the end product of glucose. The ADP and NADPH+ are recycled to the light-dependent side to start the process over.
Remember that during hours of darkness, plants cannot perform photosynthesis so they do cellular respiration in the mitochondria just as all living organisms do.
