1. Explain why fossil evidence is consistent
with the scientific theory of evolution. sc.7.L.15.1
Explanation:
The Fossil Record
Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones.
Evidence for early forms of life comes from fossils.

Volcanic eruptions, breathing, decaying dead matter, burning fossil fuels, and warm bodies of water are all carbon examples of which of the following?
A) sources
B) sinks
C) reservoirs
D) all the above
Answer:
the answer is a
Explanation:
Volcanic eruptions, breathing, decaying dead matter, burning fossil fuels, and warm bodies of water are all carbon examples of sources. Therefore, option (A) is correct.
What are sources of carbon?Carbon is one of the most important elements for life on Earth, and it can be found in a variety of sources. Some of the most common sources of carbon include:
Fossil fuels: coal, oil, and natural gas are all made from carbon-based materials that have been buried and transformed over millions of years.Plants: Plants take in carbon dioxide from the atmosphere during photosynthesis and use it to build their tissues.Animals: Animals obtain carbon by eating plants or other animals.The ocean: The ocean contains dissolved carbon dioxide, which can be absorbed by marine organisms and transformed into calcium carbonate, a key component of shells and other structures.Soil: Carbon is stored in soil as organic matter, such as decaying plant and animal material.The atmosphere: Carbon is present in the form of carbon dioxide, methane, and other gases in the atmosphereLearn more about carbon sources, here:

Make a claim about whether the sun's rays are mechanical or electromagnetic waves. Summarize evidence to support this claim and explain your reasoning.
Answer:
Se explanation
Explanation:
Mechanical waves are waves that require a material medium for propagation e.g sound waves and waves on a spiral spring.
Electromagnetic waves do not require a material medium for propagation. They can travel through space.
The light and heat of the sun are far away in outer space yet they reach us on earth. There is no intervening medium between the earth and the sun that conducts its rays to the earth. As a result of this, we can conclude that the rays from the sun are electromagnetic waves.

Heredity is the way animals and plants pass traits on to their offspring. True False
Answer:
False
Explanation:
False because Plants and Animals get their traits from their parents. Each offspring is a mix of both parents
Which of the following characteristics of a population will make it better able to adapt to environmental changes?
A.Rapid production of many offspring.
B.Specialization in one type of food source.
C.Large amount of inherited genetic variation.
D.Isolation to a limited geographic range.
Answer:
C
Explanation:
Answer: C. Large amount of inherited genetic variation.
If you had a population where the genetic variation wasn't as high or practically non-existent, then that population is likely suited to that very narrow specific environment. If the environment doesn't change, then the population wouldn't have a problem. However, the environment isn't likely to stay static. Things change all the time and this change will bring challenges to the population that was suited for the old environmental conditions.
Populations with high genetic variability will have some individuals thrive while some unfortunate members will perish. The members that die off are likely the ones who cannot adapt to the changes. As the environment changes, the individuals who survive will pass on their DNA to their offspring, allowing for natural selection to reinforce those favorable traits. Since the environment is constantly changing, whether that change is slow or fast, this means the process is continued indefinitely. So that's why high genetic variability is favored.

What does RNA do?
Is it just me or is every telling me to just die today.... like many of my friends said i should just kiII myself, that it would be better for everyone because no one would miss me... or is that juts me?
Answer:
The RNA carries out these instructions; it copies and transfers the genetic code from the DNA to ensure the relevant proteins are made. So just think of it as “DNA makes RNA make proteins”. Whereas DNA stands for deoxyribonucleic acid, RNA stands for ribonucleic acid.

Which of the following parts of the plant facilitates photosynthesis?
vascular tissue
chloroplast
roots
stoma
Answer:
chloroplast
Explanation:
it's where chlorophyll is found and chlorophyll (the green colouring pigment) is needed for photosynthesis
(b)
The image below shows part of the surface of a leaf.
0.1 mm x 0.1 mm
The length and width of this piece of leaf surface are both 0.1 mm
Calculate the number of stomata per mm of this leaf surface.
Explanation:
You didn't attach a picture so i'll just explain how to find the number of stomatas/mm^2.
first you find the surface by multiplying the length by the width
0.1*0.1=0.01mm^2
now you count the numer of stomatas in the picture
in0.01mm^2 you have.........................x stomatas
in 1mm you have ...............................y stomatas
y=100x
Would the distance from the Sun to the next closest star be more or less than
39.4 Astronomical Units? Why or why not?
Answer: The distance from the sun to the closest star would be less. I dont know why, but their is a star that is close to the sun. The average distance between them is about 23 astronomical units. 23 is of course less then the 39.4. Also the 23 is a little more than the distance between the sun and Uranus.
Explanation: ( This is new information, not old.)
The distance from the Sun to the closest star cannot be less than 39.4 AU because both stars will start attracting each other.
Astronomical Units:An astronomical unit is equal to the distance between the earth and the sun.The nearest star from our sun is Alpha Centauri which is 4.367 light-years away from our sun.If a star is just 34 astronomical units away from our sun, the sun and the closest star will start attracting each other due to the high gravitational force. This event results in the destruction of the solar system.Therefore, the distance from the Sun to the closest star cannot be less than 39.4 AU.

He continued to breed purple-flower producing pea plants together over six generations. The results of Ralph's artificial selection are shown above. What did artificial selection do to the population of pea plants? A. caused a new species of pea plant to form B. increased its genetic diversity C. decreased its genetic diversity D. caused a pea plant to exhibit a new characteristic
Answer:
C
Explanation:
The correct answer would be that artificial selection decreased the genetic diversity of the pea plant.
Genetic diversity is a measure of the number of traits or characters.
Initially, the breeding produced a considerable population of both white and purple flower offspring. But as time goes on, the population of purple flower offspring increased while that of the white flower decreased till it eventually reached zero.
Thus, artificial breeding reduced the number of traits in the population of the offspring from two to one - a case of reduction in genetic diversity.
The correct option is C.

Centrioles are cell structures involved primarily in
Answer:
In the cell, centrioles aid in cell division by facilitating the separation of chromosomes. For this reason, they are located near the nucleus. Apart from cell division, centrioles are also involved in the formation of cilia and flagella and thus contribute to cell movement.
