Answer:
Carries
Explanation:
The blood is a tissue composed of plasma (liquid) and various cells. It is a major component of the circulatory system. The blood serves majorly as a "CARRIER" helping to transport different substances throughout the body.
The blood CARRIES oxygen, nutrients, hormones and other important materials throughout the body as it circulates.

the molocules diffusing are smaller in A than in B
Explanation:
Answer:
lol its simple...
Explanation:
we know that cells have a cell membrane, also called selectively permeable membrane that allows only selective things to get in or out of the cell, so A is able to diffuse. May be B is something important to the cell...XD
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.

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.

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.

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

In science, a theory is different from how we use the term "theory" to apply to everyday ideas. The statement "It’s only a theory" might mean something very different than "theory" when used as a scientific term. What is the best way to explain the word, "theory" when used in science?
A. In science, there is no difference between a law and a theory.
B. In science, there are few principles that can be considered theories.
C. In science, a theory is well supported by observations and/or experimental data.
D. In science, a theory is a completely accurate and reliable fact about natural events.
Answer:
C
Explanation:
The correct answer would be that in science, a theory is well supported by observations and/or experimental data.
Theories are usually derived from testing hypotheses. Untested statements from observations are referred to as theories. When hypotheses are tested using a series of independent experiments and found to be true, they become theories.
Hence, theories are well supported by observations and data in science. A theory remains accurate for as long as there are no contradictory findings to it. Theories can, however, be modified once there are data to back them up.
The correct option is C.
Exchange of oxygen and carbon dioxide in the lungs uses which mode of cellular transport?
a
endocytosis
b
facilitated diffusion
c
filtration
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.
