What part of the body contains bile, an enzyme that helps break down lipids?
Bezzdna [24]

"The liver produces bile which emulsifies fats i.e. breaks them down into small droplets for a larger surface area. This will increase the rate at which the fat is digested by lipase. Bile also neutralizes the acid produced by the stomach to provide ideal alkaline conditions for enzymes in the small intestine."

Helppp, i’m going to fail:(
Westkost [7]
Don’t worry this is pretty easy :)

The answer is -
50% recessive alleles
50% dominate alleles

explication- find out what alleles you’re working with (heterogeneous and homogeneous)
[heterogeneous is 1 dominant and 1 recessive- homogeneous is 2 of the same alleles they can be dominant or recessive]
We’re working with a parent with heterogeneous and another parent with recessive homogeneous.

draw a allele chart
__
|_|_|
|_|_|
they look like this and take your first parents alleles and put them at the top

L s
_ _
|_|_|
|_|_|

it should look like this, then take your parent with both recessive and put them vertical to the box

L s
_ _
s |_|_|
s |_|_|

it should look like this, now you drag one letter down and one letter across for each box

L s
__ __
s|Ls|ss |
s|Ls|ss |
— —
it’s should look like this when they’re done, i think you’re doing a grade below me in biology so the ratio should be 50/50 for both phenotype and genotype.

TRY TO LEARN THE VOCABULARY IT HELPS A LOT AND BASICALLY TELLS YOU THE ANSWERS!
GOOD LUCK :)

The antiparallel arrangement within DNA molecules refers to Select one:
mylen [45]

Answer:

c. one helix strand that runs from the 5' to 3' direction and the other strand runs from the 3' to 5' direction.

Explanation:

A DNA molecule has <em>two strands of nucleotides with a sugar phosphate backbone each, but orientated on the opposite direction </em>allowing for the base pairs to complement one another, making it a more stable structure. <em>When two biopolymers run parallel to each other but with opposite directionality (alignment) we have an antiparallel arrangement.</em>

I annexed an image of the DNA structure.

I hope you find this information useful and interesting! Good luck!
