Mia is building a diorama showing the parts of an atom. She wants to better understand the effects of electric forces. An atom is made up of particles called protons, neutrons and electrons
The way dirt sticks to surfaces in our daily lives, such as clothing and walls, is a result of electrostatic forces on fine particle adhesion.
What is the effect of electric forces?Generally, when particle material is electrically insulating, so the electric charge may be kept, electrostatic forces become significant.
Two charges interact with one another to produce electrical forces. The electric force exerted on a single charge in scenarios involving three or more charges is simply the sum of the interactions between that charge and all other charges.
Therefore, Electric force strength is influenced by the electric charge on the particles, as well as their separation from one another.

look at the arrows pointing towards atmospheric CO2. what are two major sources of atmospheric carbon?
The two major sources of atmospheric carbon are the burning of fossil fuels and respiration by living organisms.
Sources of atmospheric carbonCarbon exists in the atmosphere mostly as carbon dioxide and carbon monoxide.
Atmospheric carbon dioxide sources include but are not limited to the burning of fossil fuels, oil, or natural gas, respiration by living organisms, volcanic activities, deforestation, mining, and so on.
The sources of atmospheric carbon monoxide include but are not limited to the burning of fossil fuels in engines, automobile vehicles, and other forms of engines that utilize fossil fuels for operation.
Carbon dioxide happens to be a major contributor to the warming of the planet. In other words, carbon dioxide is a major member of the greenhouse gases whose increased concentration in the atmosphere has been the cause of global warming and climate change that has been plaguing mankind.
Carbon monoxide, on the other hand, is poisonous to living organisms above a certain concentration threshold.

Sieve elements are the phloem cells that are still alive when they reach adulthood but have essentially no organelles left.
Sieve elements are alive at maturity but lack some organelles, such as a nucleus, in comparison to tracheary elements, which have just primary cell walls (and consequently thicker overall cell walls).
Thin-walled cells called sieve elements typically don't have nuclei but are nonetheless alive at maturity despite having a significantly altered protoplast. .The primary walls of parenchyma cells are thin, and they typically continue to live after reaching maturity. The primary type of elongated photosynthate-conducting cell in vascular plants' phloem is known as a sieve element.

Identify from which region of the vertebral column each vertebrae belongs to. What are the differences between the size of the body, vertebral foramen, and spinous processes?
Within the various regions of the spine, the vertebrae vary in size and shape, but they all follow similar structural patterns.
What is spine?Your spine, or backbone, is the central supporting structure of your body. It connects different parts of the musculoskeletal system. The spine helps us sit, stand, walk, twist and bend. Back injuries, spinal cord disorders, and other problems can damage the spine and cause back pain. The spine is the central supporting structure of our body. The spine is a chain of bones, but it is made flexible by elastic ligaments and intervertebral discs. The vertebrae are generally numbered and divided into different regions. Neck, chest, lumbar, sacrum, coccyx. Only the top 24 bones are movable.To learn more about spine from the given link :

Picture 1 is a part of cervical vertebrae and picture 2 is a part of thoracic vertebrae.
What is cervical and thoracic vertebrae?
The C1–C7 vertebrae, which make up the cervical spine (neck area), are connected to one another by intervertebral discs. These discs provide the spine with mobility and serve as shock absorbers when people are moving around.There are 12 vertebrae in the thoracic area, identified as T1–T12. Spinal nerves emerge through a space created by the intervertebral discs, laminae, pedicles, and articular processes of neighboring vertebrae. Combined, the thoracic vertebrae form a kyphotic curvature.Difference between size of the body, vertebral foramen and spinous processes:
Regardless of body size, nearly all mammals have seven cervical vertebrae. This indicates that there are significant differences in the size of cervical vertebrae, ranging from the shrew's relatively short cervical vertebrae to the giraffe's neck's much lengthened vertebrae. Each cervical vertebra in a fully mature giraffe measures 11 inches in height.The spinal cord and its meninges are located in the vertebral foramen. The spinal cord is located in this spacious passageway that runs up and down inside each vertebra; it is commonly referred to as the spinal canal rather than the vertebral foramen.The lumbar spinous processes (LSP) provide a crucial anatomical and biomechanical purpose by anchoring the interspinous and supraspinous ligaments, as well as the intersegmental paraspinal muscles and safeguarding the neuronal structures in the spinal canal.Hence one is cervical vertebrae and the other is thoracic vertebrae.

Select the answer that best describes the relationship between photosynthesis and cellular respiration.
Question 5 options:
Cellular respiration and photosynthesis have a linear relationship where cellular respiration creates energy for photosynthesis to occur.
Photosynthesis uses light eneregy to create the carbon dioxide needed for cellular respiration to occur while cellular respiration also creates carbon dioxide that is released into the atomosphere. This creates a positive feedback loop of carbon dioxide production.
Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen which is needed for cellular respiration to occur. Cellular respiration takes the glucose and oxgyen and produces water and carbon dioxide that is needed for photosynthesis while also producing energy.
Celluar respiration uses the energy from the sun to create ATP which is used in the process of photosynthesis to produce oxygen and water which are essential to life on this planet.
C. ''Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen which is needed for cellular respiration to occur.
Cellular respiration takes the glucose and oxygen and produces water and carbon dioxide that is needed for photosynthesis while also producing energy'' this is the correct answer.
What is the difference between Photosynthesis and respiration?Photosynthesis is a process that occurs in the body of plants in which carbon dioxide and water are converted into oxygen and glucose in the presence of light energy. In this process of photosynthesis, oxygen is released into the atmosphere whereas glucose is stored in different parts of the plant body.
Glucose is used as food by the plant generating energy in the form of ATP and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide with the release of energy. Water and carbon dioxide are the by-products of cellular respiration and ATP is energy that is transformed from the process of cellular respiration.
So we can conclude that option C is the correct answer.
