Answer: Thermal energy flows from a warmer material to a cooler material. When thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three ways heat is transferred into and through the atmosphere: Radiation, conduction and convection.
Radiation is when energy, in the form of electromagnetic radiation, is emitted by a heated surface in all directions and travels directly to its point of absorption at the speed of light; thermal radiation does not require an intervening medium to carry it. Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it.

Often, the shape or structure of a cell is related to its_________
Answer:
Cells are limited by their surface area to volume ratio and they come in many different shapes. A cell's function is determined, in part, by its shape.
mark me as brainliest if u found it helpful
Answer:
Function
Explanation:
The shape of the cell, the organelles within it as well as how many of those organelles are present play a huge role in the cells function.
For example, muscles cells will have lots of mitochondria that are used for ATP production, needed in movement.
Lung cells will have ridges or groves in them that increase the cells surface area that make them much more effective at the diffusion of oxygen and carbon dioxide when breathing.

Georgia has hypochondriasis, and Leo has a pain disorder. Which of the following do Georgia and Leo most likely
have in common?
O a history of normal medical exams
O significant pain in a specific area
O a preoccupation with the idea of being sick
O an onset of the disorder before the age of 30
Answer:
C. a preoccupation with the idea of being sick
Explanation:
Hypochondriasis and pain disorder are two conditions that deviates from the normal human health. Hypochondriasis, also known as health anxiety, is a condition whereby an individual is fearfully worried about having a serious illness. On the other hand, pain disorder is a condition in which pain results in certain areas of an individual's body due to psychological disposition of such individual i.e. his/her mindset.
Based on the description of both conditions above, it can be observed that both hypochondriasis and pain disorder are as a result of a preoccupied mindset of being sick. One is worried PSYCHOLOGICALLY about being terribly ill (Hypochondriasis) while the other PSYCHOLOGICALLY induces pain on him/herself.

How does fossil evidence determine the relationships of whale ancestors and their descendants?
Similarities in the bone structure, the genetic composition, chemistry of the teeth etc
Explanation;Fossils are the trace or remains of an organism that lived long ago. Fossils provides a lot of evidence concerning the ancestors of whales.Fossil evidence shows that a land mammal the lived between 50 million and 70 million years ago. It is thought that whales evolved from these ocean-dwelling mammals.Whales Descended From Tiny Deer-like Ancestors. Scientists found that whales are mammals whose ancestors walked on land.The structures of the bones and chemistry of the teeth of a close relatives of whales such as Indohyus,indicates that they spent most of their time in water.Answer: If the fossil evidence determine the relationships of whale ancestors and their descendants, then they can see what are the remain of the fossils are the trace or remains of an organism that lived long ago.

Which is abiotic?
tree sap
O insect
O sunlight
O tree stump
Answer:
Sunlight is abiotic. Abiotic is a non living thing
Sunlight is an abiotic factor. Therefore, the correct statement is option C.
What do abiotic elements consist of?Sunlight is an inanimate element of the environment, making it an abiotic one. Insects and tree sap are both living things, and a tree stump is a decomposing piece of the environment that was once alive.
Abiotic elements are the ecosystem's non-living parts. They include natural elements including sunshine, water, air, temperature, soil, and minerals as well as physical and chemical elements. In contrast, biotic factors include live species, including plants, animals, fungi, and bacteria.
Sunlight is a crucial abiotic component of ecosystems because it fuels photosynthesis and influences the development and behavior of living things. It also affects weather patterns and climate, which may have a big influence on ecosystems.
Therefore, sunlight is an abiotic factor including natural elements including sunshine, water, air, temperature, soil, and minerals as well as physical and chemical elements.

Which of the following ways are leftover neurotransmitters cleaned up if they
have not been accepted by the postsynaptic neuron?
Pick 2
the neurotransmitters are broken down in the synapse
the postsynaptic neuron absorbs the neurotransmitters
The presynaptic neuron absorbs the neurotransmitters
the neurotransmitters are built up to create a new neuron
Answer:
The correct answer is -
the neurotransmitters are broken down in the synapse
The presynaptic neuron absorbs the neurotransmitters
Explanation:
The termination of the neurotransmitters is essential as if they can cause harm by continuing the stimulus effect on the muscles or cells. To clean up these neurotransmitters there are two ways- Degradation of neurotransmitters with the help of enzymes in the synapses or synaptic cleft and the presynaptic neurons absorbs or suck up neurotransmitters. The neuron (presynaptic neuron) is that releases the neurotransmitter like dopamine, serotonin, is the one that re-uptake it.
This reuptake is done by transporter proteins that are are symporters in nature as these proteins pump neurotransmitters as well as ions back into the neuron.

please help. i’m literally going to fail biology
Answer: Cell biology encompasses both prokaryotic and eukaryotic cells and can be divided into many sub-topics which may include the study of cell metabolism, cell communication, cell cycle, biochemistry, and cell composition. Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions. The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.

What term is used to describe the state in which molecules are evenly distributed in the available space?
Answer:
equilibrium
Explanation:
The term that is used to describe the state in which molecules are evenly distributed in the available space is dynamic equilibrium.
The molecules of a substance refers to a group of two or more atoms of the substance held together b chemical bonds.
Molecules of solids are fixed about a particular point except they are dissolved in solution. Molecules of liquids and gases, however, move about randomly.
When the molecules of a particular substance are more to one side between two adjacent points in a space, a gradient is created. However, when the molecules of the substance are uniformly distributed in a space, they are said to be in dynamic equilibrium.

why do the processes and events dating back to the big bang eventually led to the existence of life on earth
Answer:
Stars are formed such that their death led to the creation of life.
Explanation:
The Big Bang theory was developed in 1927. This theory helps to understand how the universe was created. According to this theory, hydrogen gas was created through a process of expansion and explosion. As a result, stars are formed such that their death led to the creation of life.
Earth formed around 4.54 billion years ago which is equal to approximately one-third of the age of the universe.
