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.

The DNA of a cell is not
programmed to coordinate the
activities needed to keep a large
cell alive. How does cell division
help the cell avoid DNA overload?
A. When a cell divides there is much less DNA
created than in the large cell, increasing the
overload.
B. Each daughter cell has its own copy of DNA
and can coordinate all the activities of a smaller
cell.
C. Cell division does not help cells to avoid DNA
overload.
Answer:
the DNA of a cell is not programmed to coordinate the activities needed to keep a. large cell alive. how does cell division help the cell a void DNA overload
The process of cell division helps the cell to avoid DNA overload by the following mechanism:
Each daughter cell has its own copy of DNA and can coordinate all the activities of a smaller cell.Thus, the correct option for this question is B.
What is Cell division?Cell division may be defined as a process through which a parent cell significantly divides into two daughter cells with an identical amount of genetic material.
DNA overload deals with the mechanism of the larger the cell, the greater the requirement for the positioning of the cell's DNA. In order to prevent this mechanism, a cell undergoes the process of division that limits the phenomena of DNA overloading.
This happens with the help of synthesizing two new daughter cells that limit the size of the parental cell.
Therefore, the correct option for this question is B.

Which evidence of evolution allows scientists to know what the physical features of an organism were ?
The table shows mass and volume measurements in an investigation that involves vinegar and baking soda, both before and after the chemical reaction.
What evidence supports the law of conservation of mass?
The mass remains constant before and after the chemical reaction
The volume of the products is more than the volume of the reactants, so it does not support the law of conservation of mass.
The mass of the gas is more than the mass of the baking soda, so the mass is constant
The density of the products is less than the reactants, so the mass is constant.
Answer:
mass will be less
Explanation:
A chemical reaction takes place when vinegar and baking soda are mixed. One of the new substances formed is carbon dioxide gas. If the carbon dioxide gas is contained, the mass of the substances will stay the same according to the Law of Conservation of Mass. If the gas is allowed to escape, the mass will be less

what is living thing that work together to coexist?
Answer:
When a group of individual organisms live together in one place we call it a population. A population is defined as a group of organisms from the same species that live together in the same area.
Explanation:
Coexistence: living harmoniously with wildlife in a human-dominated world is a primer on IFAW’s mentality that coexistence is better than conflict. People’s relationship with native wildlife is often that of conflict. Animals such as coyotes, wolves, bears, and beavers are considered “nuisances” and are treated as something to be controlled. The result is millions of animals killed in barbaric ways every year by governments, all to “reduce conflict.” This report highlights examples of people finding innovative, yet simple ways to coexist with wildlife so that we can live side by side with these species. IFAW understands that not only are native wildlife species important to protect, but they are also essential to the ecosystem and therefore our own well-being. We work every day to make the planet a better place for both people and animals.

What is the difference between natural selection and artificial selection? Explain why?
Answer:
Natural selection is not decided by humans, but aritifical is. In natural selection, the organism that naturally survives will have their selection of characteristics carried onto the offspring. But in artifical, humans decide which characteristics they want from an offsrping for their sepcific need, e.g largest or colour and breed organisms for that characteristic- not to make them survive better.
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.

Changes to body cells affect(1 point)
gene activity.
cell division.
individuals.
offspring.
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 are some disadvantages of fossil fuels?
A Fossil fuels deplete Earth of its historical materials.
B Fossil fuels are nonrenewable and may cause pollution.
C Fossil fuels are relatively cheap to produce and easy to use.
D The use of fossil fuels depletes our forests of resources.
Answer:
B. Fossil fuels are nonrenewable and may cause pollution.
Explanation:
Fossil fuels are nonrenewable, meaning that they cannot be replenished sustainably. So, eventually, we will run out of them because they cannot be renewed.
Another disadvantage of fossil fuels is that they cause pollution. For example, the gasoline that is used by cars creates significant amounts of pollution every year.
Pollution is created by cars, factories, homes, and everything else that uses fossil fuels.
So, the correct answer is B, fossil fuels are nonrenewable and may cause pollution

Why must the cell make sure it duplicates its
organelles and DNA before mitosis occurs?
Explanation:
Cells will duplicate or copy their DNA right before they divide. The process of cell division is called mitosis. Since the cell is dividing it needs two copies of its DNA - one is kept by the parent cell and the other is passed to the daughter cell. ... So this process of duplicating DNA is very important.

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.
