Hope it helps, mate. Good luck! :3
Your friend makes a claim that the image to the right shows facilitated
diffusion. You are an educated Honors Biology student, and you believe
that he/she is incorrect in their claim. Make a claim as to which type of
cellular transport is represented in the image (1 point)State TWO pieces of
evidence from the image that supports your claim (2 points).*
Answer:
Facilitated diffusion is a type of passive transport of molecules down the concentration gradient between two sides of a membrane which doesn't require ATP and instead uses a specific transmembrane protein.
Active transport requires instead ATP and it is the process drawn in the figure. Moreover the figure illustrates that molecules are moving against their concentration gradient.
In guinea pigs, short hair, S, is dominant to long hair, s. Cross a heterozygous short hair with a long haired Guinea pig.
Answer:
P1: Ss x ss
F1: S s
s Ss ss
s Ss ss
Genotypes: 1 Ss : 1 ss
Phenotypes: 1 short hair : 1 long hair
1. What phenotypes would you predict in the F2 generation?
Answer: Round
Explanation:
That's what i put on mine lol
Answer: 75% Round 25% wrinkled
Explanation:
This dichotomous key helps scientists classify within the arthropoda phylum. If scientists discover an organism with: less than 10 legs, 6 legs, wings, wings with 1 or 2 colors, with legs that are approximately the same length, wings that are not net-like, and wings that meet in a straight line down the back, how would this organism be classified?
You'll have to follow the dichotomous key that's provided to you. Start by choosing less than 10 legs, then choose 6 legs, then with wings, then wings with 1 or 2 colors... etc. You should end up identifying an organism this way.. following the path.

a structure in a present day organism that no longer served its natural purpose
Answer:
Vestigial structures
Explanation:
Vestigial structuresserve little or no present purpose for an organism. The human tail, which is reduced to the tailbone during development, is one example.
Explain the difference between prokaryotes and eukaryotes. Include which type of microorganisms are included in each domain
Answer:
eukaryotic cells have a distinct nucleus containing the cell's genetic material, while prokaryotic cells don't have a nucleus and have free-floating genetic material instead.
Explanation:
which instrument would produce
sound with the longest wavelength?
a. Flute
b. Bass guitar
C. Violin
d. cymbal
Answer: Long wavelengths are the result of a deeper sound since it takes longer for it to travel through a medium. The Bass Guitar is your best bet as it is the lowest sounding instrument, meaning is had the longest wavelength.
What are the 3 most important parts of a seed
Answer:
the 3 primary part of a seed are the embryo, endosperm, and seed coat.
expaination:The embryo is the young multicellular organism before it emerges from the seed.
what measures to be taken in an operating room
Answer:
infection control- clean equipment to prevent spread of germs
All items needed for the operation should be in place and an adequate supply of regularly used items should be on hand to minimise movement to and from theatre during the operation
Everything needs to be sterile
All instruments need to be inspected for any signs of contamination after the sterilisation process
Shoes from outside should never be worn inside an operating room
Theatre hats are worn routinely, and prevent loose hair and skin from falling on wounds or equipment
The surgical mask was introduced over a century ago. Its continued use is controversial as evidence is not conclusive that wearing a mask reduces postoperative infection. Wearing a mask, however, does protect the practitioner from contact with body fluids
Explanation:
Diffusion is the movement _____.
of molecules to an area of lower concentration
of molecules through the cytoplasm of a cell
of water through a selectively permeable membrane
of molecules to an area of higher concentration
Answer:
of molecules to an area of lower concentration

What happens during fermentation?
Answer:
Fermentation, chemical process by which molecules such as glucose are broken down anaerobically. More broadly, fermentation is the foaming that occurs during the manufacture of wine and beer, a process at least 10,000 years old.
Explanation:
Hope that this helped you :D
Which is the best explaination for how chemical energy is transferred with cells
Answer:
Inside the cell, each sugar molecule is broken down through a complex series of chemical reactions. As chemical energy is released from the bonds in the monosaccharide, it is harnessed to synthesize high-energy adenosine triphosphate (ATP) molecules. ATP is the primary energy currency of all cells.
Explanation:
you did not give any choices by the way
but hope this helps
guys help with this plzz
brainlest even if u try ur best :
Vasoconstriction and Vasodilation
__________ carries heat from the core around the body.
As blood flows through the ______________ close to the surface of the ______, heat is lost to the body’s surroundings.
The __________________ which supply the capillaries in the skin have smooth _________ in their walls. This means that the arterioles can dilate or constrict to ____________ the flow of blood into the capillaries.
Explanation:
is it only vasoconstriction and vasodilation as the answers or are there more?
please help! i dont really get this at all
Answer:
The slope between the red points is 2/4 (simplified it is 1/2). The slope between the green points is 4/8 (simplified it is 1/2). This shows that by taking ANY two points on the line, you will find the same slope.
