Question 1
Organisms reproduce to pass on their genes to the next generation. Which type of
reproduction produces greater genetic diversity or more gene variation?
Asexual Reproduction
Sexual Reproduction
O Both types of reproduction produce great diversity,
Answer: sexual reproduction.
Explanation: In asexual reproduction there is no exchange of genetic characteristics due to the lack of fusion of gametes(haploid). Thus there is practically no variation in specie.
But in sexual reproduction there is exchange of genetic characteristics resulting from the fusion of haploid gametes hence there is variation and great diversity.
What do you think the relationship is between frequency, amplitude, and wavelength?
Answer:
The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

how does gas volume relate to vasodlation and vasoconstriction
Answer:
Direct relation.
Explanation:
The gas volume has direct relation to vasodilation and vasoconstriction because both vasodilation and vasoconstriction is responsible for allowing gas through the blood vessels. Vasodilation is the widening of blood vessels whereas Vasoconstriction is the narrowing of blood vessels by small muscles in their walls. So when the blood vessels are widen, the gas volume increases due to more space in the blood vessels while on the other hand, if the blood vessels are narrow so the gas volume decreases in order to easily flow in the blood vessels.

Analyze the graphs below. Which growth model would apply to a population of squirrels arriving on a new island? Assume the squirrels have no way to leave.
Please explain if possible!!
Answer: The Logistic Growth graph
Explanation: Assuming the population is growing as both graphs show population growth. The squirrel population will get so big they will then have limited resources to carry that population size so then it will start to decline. So then the population will reach a Carrying capacity

2. How many types of rocks make up the Earth’s crust?
3. How are igneous rocks formed? What is another name for igneous rocks?
4. What is the difference between two types of igneous rocks?
1-A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. ... A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.
2-Part of Hall of Planet Earth. There are three kinds of rock: igneous, sedimentary, and metamorphic.
3-Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet. When lava comes out of a volcano and solidifies into extrusive igneous rock, also called volcanic, the rock cools very quickly.
4-Igneous rocks are formed from lava or magma. Magma is molten rock that is underground and lava is molten rock that erupts out on the surface. The two main types of igneous rocks are plutonic rocks and volcanic rocks. Plutonic rocks are formed when magma cools and solidifies underground.

Pretend that you are writing a letter to the president proposing ways that the US can reduce its contribution to climate change. In your letter, include at least three facts you learned today.
Answer:
Dear Mr. President,
Your strong voice has called attention to the risks of human-induced climate change and the need to take timely and effective steps to address it. We are pleased to report further progress in our efforts to advise you on climate policy options that could help encourage these steps.
- (Explain what you learned in class today ) I don't know what you were taught in class so you have to figure what to put here.
Mr. President, our temperatures are consistently rising while moisture is increasingly evaporating. Forest management is merely one piece of the puzzle — something our own firefighters would be quick to remind you. Since 2009, our state has spent more than $130 million on forest health and fire preparedness. These events still overwhelm our residents and resources, because these fires are unlike anything people have seen before.
