Certain materials are needed by the mitochondria to make energy. Which of the following is most responsible for getting the
materials into the cell?
O A The materials need to Love through the cytoplasm to get to the mitochondria
B The cell membrane lets the materials into the cell so they can get to the mitochondria
OCThe cell wall lets the materials into the cell so they can get to the mitochondria
D. The materials need to move through the lysosome to get to the mitochondria
Answer:
C. The cell membrane lets the materials into the cell so they can get to the mitochondria
Explanation:
The cell membrane regulates the entrance and exit of certain molecules inside the cell. Some molecules can easily pass through the phospholipid bilayer via passive transport. Others use protein channels, and some require movement by active transport, or endocytosis.

Perform online research to learn about an invasive species and its new environment. Discuss how the species was introduced to the environment, where it is invasive, what advantages the species has over native species in this environment, and what problems the species poses to the environment.
Answer:
(Answers may vary.)
Farmers brought nutria, a type of large rodents, from South America to North America in the 1990s. They wanted to raise the rodents for their fur. Some of these rodents escaped into the wild and became a major pest in the Gulf Coast and Chesapeake Bay regions. Grasses and shrubs in these regions are vital, because they provide food and shelter for many species. They also help in preventing soil erosion. The nutria are eating up all the grasses and shrubs, which affects the food cycles of these regions. The entire ecosystems are being disrupted.
Moreover, nutria pose a direct threat to humans. These rodents are an effective vector for carrying parasites that can cause disease in humans. They also damage property. The burrows created by nutria can damage dams and building foundations as well as cause erosion near streams and lakes.
Explanation:
the answer from pluto/edmentum
Answer:
The apple snail is a native species of Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Southeast Asia legally imported this alien species to use it as a protein source. Later, this species was brought to places like Hawaii as a source of food.
Like most, if not all, invasive species, the apple snail outcompetes native species for resources. This is because it reproduces rapidly (laying hundreds of eggs every few weeks) and lacks predators. As a result, the snails spread rapidly to aquatic biomes and modify the natural balance of aquatic ecosystems.

Answer: See explanation
Explanation:
When volcanic eruptions occur, there are a lot of magma i.e. molten rocks that are formed under the volcano. This formation of the magma and their movement is referred to as magmatism. The magmatic process has an impact on the way magma melts.
Magmatism can be used as an acronym in the following way:
M - Molten
A - Assimilation

Exchange of oxygen and carbon dioxide in the lungs uses which mode of cellular transport?
a
endocytosis
b
facilitated diffusion
c

d
simple diffusion
Answer:
D: Simple Diffusion
Explanation:
Diffusion is a transport driven by a concentration gradient. Gas molecules move from a place of high concentration to an area of low concentration. Knowing when blood is low in concentration and high in carbon dioxide it goes under gas exchange with air into the lungs.

What is the function of mRNA?
What is the function on tRNA?
Describe what happens during transcription.
Describe what happens during translation.
Explain how DNA is used to make a protein.
Answer:
DNA Replication:
Replicate the following strand of DNA:
Original DNA: A T G A A C CA T T C A G T A T G G
Complementary DNA:
Remember that the complimentary base pairs in DNA are Adenine-Thymine and Guanine-Cytosine, or A-T and G-C. This means that if the original sequence is:
A T G A A C C A T T C A G T A T G G
Then the compliment is (replace with the opposite base pairs):
T A C T T G G T A A G T C A T A C C
Transcription:
Transcribe the DNA to make an mRNA molecule
COMPLIMENTARY DNA:
mRNA Molecule:
So if our complimentary DNA (antisense stand) is T A C T T G G T A A G T C A T A C C then to transcribe, we basically create another complimentary strand, but for mRNA, we use Uracil instead of Thymine:
A U G A A C C A U U C A G U A U G G
Translation:
Translate the mRNA into the corresponding amino acids.
mRNA MOLECULE:
AMINO ACID:
Using the DNA sequence provided, determine the amino acids.
Next, take each codon (3-base set) to the table and record the corresponding protein:
A U G = Methionine (start)
A A C = Asparagine
C A U = Histidine
U C A = Serine
G U A = Valine
U G G = Tryptophan
ORIGINAL DNA: A T G G G T C T A G C G A A A G A T
Complementary DNA:
mRNA DNA Molecule:
Amino Acid:
And we do it all again:
A T G G G T C T A G C G A A A G A T = original DNA
T A C C C A G A T C G C T T T C T A = complementry DNA
A U G G G U C U A G C G A A A G A U = mRNA
A U G = Methionine (start)
G G U = Glysine
C U A = Leucine
G C G = Alanine
A A A = Lysine
G A U = Aspartate

What do the results of the agar blocks indicate about the relationship between cell size and time for materials to reach the center of the cell?
Include an explanation of how the surface area-to-volume ratio, diffusion rate, and time for substances to reach the center are related. Support your explanation with data.
PLZ HELP!!! 50 points!!!
There is inverse relationship between cell size and time to reach the center.
Cell size has a inverse relationship with the time that the materials needed to reach the center of the cell because if the cell size increases more time is required for a material to reach to the center of the cell due to more distance between the center and boundary of the cell. The surface area-to-volume ratio, diffusion rate, and time for substances to reach the center are related to each other.
If the surface area to volume ratio is higher than more materials can diffuse across the membrane of the cell but more time is required to reach the center because increase in cell size leads to more distance between center and boundary of the cell so we can conclude that there is inverse relationship between cell size and time to reach the center.

Explanation:
Wegener used evidence of climate change to support his hypothesis. As a continent moves toward the equator, its climate becomes warmer. As a continent moves toward the poles, its climate becomes colder. But the continent carries with it the fossils and rocks that formed at its previous locations.
