Answer:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
Explanation:
What's the connection between epigenome and nature vs nurture?
Answer:
The survival and proper functioning of an organism depends on a finely tuned interface between genome and environment, nature and nurture. The interface that regulates gene expression through environmental feedback is called the epigenome.
Explanation:
The cells of a plant help the plant maintain its life functions. What part of a plant cell has the function of producing sugar in the presence of sunlight?
Answer:
CHLOROPLAST
Explanation:
As stated in this question, plant cells are capable of producing their own food in form of sugar (glucose) using energy from sunlight in a process called PHOTOSYNTHESIS. Photosynthesis is the process by which green plants and other certain organisms synthesize their own food using light energy.
The ability to carry out this photosynthetic function is embedded in a structure found in plant cells called CHLOROPLAST. Chloroplast contains a pigment called CHLOROPHYLL, which captures light energy from the sun. Generally, the the function of producing sugar in the presence of sunlight (photosynthesis) occurs in the CHLOROPLAST.
A student conducted a comparative investigation to test the hypothesis that different areas of New York City have different levels of air pollution. Which is a likely benefit of this comparative investigation?
A It provides her with a large amount of information about air pollution in New York City.
B It provides her with results that are valid for a long time.
C It requires that she observe a limited number of variables.
D It allows her to learn about the causes and effects of air pollution in major cities.
Answer: A. It provides her with a large amount of information about air pollution in New York City.
Explanation:
A comparative investigation is when data is collected in order to make a particular comparison.
With regards to the question, the student conducted a comparative investigation in order to test the hypothesis that different areas of New York City have different levels of air pollution.
The benefit of this study done by the students is that it will provide her with a large amount of information about air pollution in New York City. The area with the highest air pollution, what causes air pollution and other necessary information can be gotten.
Therefore, the option is A.

A population of antelope lives on the African Savannah and is hunted by lions. Explain how a mutation that allows some antelope to run faster than others might lead to the evolution of this population . *
3 points
Your answer
Answer:
The individual carrying this beneficial mutation will be selected through natural selection.
Explanation:
Mutations are genetic changes in the DNA sequence. When mutations occur in the germline, these genetic modifications can pass from one generation to the next. In general, mutations are deleterious, but there are exceptions where they may be beneficial for the individual and provide the raw material for evolutionary change. An individual carrying one beneficial mutation will have more chances to survive and reproduce than individuals without this mutation, and thereby such genetic change will increase its frequency in the population.

PLEASE HELP!!!? Are humans an invasive species? Why or why not. GIVE TWO PIECES OF EVIDENCE TO SUPPORT YOUR OPINION.
Answer:
I think yes, humans are an invasive species.
Explantation:
I think humans are an invasive species because they are everywhere, and very few places in the world do not have humans. Humans are in control of the planet because of their number. Humans are not going to be extinct ever. They are always going to be here on earth. If somebody finds new land, they make a base/camp and send other people to live there and to populate it. Like in North america, settlers came and sent men to live there. They hunted animals and set up homes. Then, more and more people came and soon all that is left is a over populated land with citys and cars and humans everywhere.
I hope this helps. :)
Ruby has observed that plants in her garden vary in height. She wants to investigate whether a plant species (species A) grows faster than the other garden species (species B, C, and D). Select the statement that describes Ruby gathering enough evidence to support a scientific explanation concerning plant growth rates
Answer:
This question lacks options, the options are:
A) Ruby measures the heights of several species A, B, C, and D plants for a week under different conditions and finds a journal article that describes the growth rate of species A.
B) Ruby measures the height of a species A plant for a week and finds an anonymous gardening blog that describes the growth rate of species A.
C) Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions.
D) Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions and finds journal articles that describe the growth rates of each species.
The answer is D
Explanation:
According to this question, Ruby wants to investigate whether a plant species A in her garden grows faster than other plant species (B, C and D) due to the varying height she observed in them. To do this, Ruby will need to conduct a scientific investigation by measuring the height of all the plant species she is trying to compare (A, B, C, D).
However, she must do the measurements under the same conditions i.e. controlled in order not to influence the result. In order to make a scientific explanation concerning the plant growth rates, Ruby should find journal articles that describe the growth rates of each species and make comparison with her experimental/measured height values.

How does the number of valence electrons in sodium (Na) compare to the number of valence electrons in calcium (Ca)? A. Na has two fewer valence electrons than Ca. B. Na and Ca have an equal number of valence electrons. C. Na has one more valence electron than Ca. D. Na has one fewer valence electron than Ca.
Answer:
D. Na has one fewer valence electron than Ca.
Explanation:
Elements in different groups has been grouper based on the number of valence electrons they possess. Valence electrons refers to the electrons at the outermost part of the shell of an atomic element.
Sodium (Na) belongs to group 1 on the periodic table meaning that it has one number of valence electrons while Calcium (Ca) belongs to group 2 meaning that it has two number of valence electrons. Hence, Na has one fewer valence electron than Ca.

What could explain the curve in this population growth graph? A graph has time on the horizontal axis and population size on the vertical axis. The population size was constant for a period of time, increased rapidly, and then became constant again. an unlimited food supply a natural disaster a population crash a reduction in predators
Answer:
A reduction in predators
Explanation:
I just took the test
A reduction in predators could explain the curve in this population growth graph.
How does reduction in number of predators lead to curve?The prey species soon degrades and overruns its area since there are no predators to regulate the population and modify feeding behavior.When food becomes scarce, people grow unwell and famished, and they either flee or crash.When predator populations grow, putting more pressure on prey populations and acting as a top-down control, pushing them toward extinction. As a result, the size of prey populations is influenced by both resource availability and predation.
