Explanation:
Conduction is the transfer of heat between substances with different temperatures. Heat moves from the warmer to the cooler substance through direct contact.
Answer:
True.
Explanation:
Conduction is a heat transfer method. The heat passes by direct contact between two objects. The heat will go from the object with the higher temperature to the one with the lowest one. We call this temperature gradient. If we analyze the molecular aspect of conduction, we can see that the molecules with higher temperatures have more energy so, they move more. These molecules will collide with the molecules of the other object transferring their energy. As a result, heat passes from the hottest object to the cooler one till the two substances are at the same temperature, there is thermal equilibrium.

Which evidence of evolution allows scientists to know what the physical features of an organism were ?
Using the list of events in the article, complete the diagram to show a cause, its effects, and then the response. Please help me 
:(
Answer and Explanation:
Cause: The plague swept across Europe.
Effects:
1. Production slowed down
2. The price of grain dropped.
3. The population of cities fell
Response: Italians began making wine, oil, and cheese.
(This is correct assuming that the plague occurred first when stated in the article)
So, why is it like this?
We know that a plague is a infectious and super contagious disease that can be transmitted by infected fleas, and is known for killing many people.
So, it makes sense that because this plague happened, we would see a price of grain drop, since the amount of workers were shortened from the plague, and there are less people to buy the grain for the factories and businesses to gain the money from the people's shopping of grains.
That has the production slowed down, so there is less food and grain, and the population would decrease as people were dying from the plague.
This results in the Italians making wine, oil, and cheese to combat the plague.
I'm sorry if this is wrong, and hopefully the article tells you in order the events that occurred. This is my best guess, and what makes sense to me.

By what time had most small farms in the US been replaced by large farms?
A.The Agricultural Revolution
B.World War II
C.World War I
D.The Civil War
Answer:
Small and Family Farms. More than 90 percent of farms in the U.S. are classified as small, with a gross cash farm income of $250,000, or less. These farms, most of which are family-owned and operated, confront considerable challenges due to current trends, such as increased movement into cities, an aging population, farm consolidation, and changing weather patterns.

7. What is meant by the saying everything that is psychological is also biological
Answer:
People who work in psychology want to understand human behavior and where it comes from. The mind-body dualism debate is an ongoing discussion on whether or not the psychological activity of an individual is based entirely in their body, or if there is a higher consciousness separate from the body. The debate stretches back hundreds of years in the field of philosophy, where philosophers have argued whether everything is material, or if there is a separate, immaterial part to being human.

What do you mean by chromosomes?A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.
Moreover, chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).
Therefore, passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

Heather and Matthew take 60 sec to walk eastward along a straight road to a store 90 m away. What was their speed?
Answer:
1.5m/s
Explanation:
Using the formula;
Speed (m/s) = distance (metres) ÷ time (seconds)
According to the information provided in this question, Heather and Matthew spend 60seconds to travel a distance of 90 metres. This means that t = 60s, d = 90m
Hence,
Speed = 90/60
Speed = 3/2
Speed = 1.5m/s.
In photosynthesis, what gives energy to the electron moving through the electron transport chain?
A.
water
B.
NADPH
C.
light
D.
ATP
Answer:
In photosynthesis, light gives energy to the electron moving through the electron transport chain. So its C.
Explanation:
In the photosynthesis of plants, the light gives energy to the electrons passing through the electron conveyor chain. This Light energy is then transformed to chemical energy, which creates ATP; an energy storehouse molecule, and NADPH, a decreased electron transport. Moreover, light energy is utilized to elevate protons across a membrane to compose a proton-motive force.
Answer:

how do greenhouse effect allow for there to be life on earth? Explain
Answer:
A greenhouse effect is when a planets atmosphere gets thicker and warms
Explanation:
As a planet with water's parent star gets brighter every million years, The amount of evaporation increases. these are called greenhouse gasses. greenhouse gasses include water vapor and Carbon. This is why Venus is a burning hell. it was once like earth, but the sun kept getting brighter and brighter, causing clouds to form all over the rock, trapping in more heat, and making it far to hot for even metal. One day this will happen to earth, as well. this is why we have global warming. It can be caused by Co2 from earth's inhabitants and water vapor from it's vast oceans.

Answer:
Explanation:
Genes contain specific instructions for how to make proteins within the body.
Epigenetic changes are generally heritable genetic changes that are due to environmental factors, which work by turning genes that already exist in the body 'on' or 'off' depending on these factors.
Meiosis produces gamete cells. This is usually a total of 4 gamete cells which are all part of producing everything required in the reproductive process.
exposure to extreme heat is probably the most likely cause of mutation for E. Coli as it needs a steady 36–40°C for survival.
Changes to body cells affect cell division. This is because genetic mutations cause cells that are designed for normal cell growth to greatly increase which can throw the system off and cause many problems.
1. Proteins
2. Heritable genetic changes that are due to environmental factors
3. Gamete cells
4. Exposure to extreme heat

What is the theory of natural selection, and why does it occur in an organism? Give an example.
Answer:
It occurs in organisms because an organism with a beneficial trait/mutation have a higher chnace of surviving compared to organisms that do not. So the organsims that do survive pass on their genes to the next generation, and the bext generation will pass on those genes to the generation after and so on. But all the organisms that do not possess a beneficial trait/mutations will not survive, therefore they cannot reproduce and pass on those genes to their offspring. This means that most of the population will posses that trait/mutation.
Example: Spotted moths camouflage with bark so they are seen by predators and eaten. Black moths are easily seen by predators and are eaten. Spotted moths then pass on their genes to the next generation of moths.
