Question

Which of the following would most likely happen if DNA polymerase were not functioning properly during DNA replication?

Any of the nitrogenous bases in the DNA strands would be able to form base pairs with each other.
The new strands of DNA would not be an exact copy of the original DNA.
The two strands of DNA would separate from each other and be unable to reform.
Hydrogen bonding between nitrogenous bases would cause the DNA to fold upon itself.

Answer 1

@steve816 please help me

Answer 2

hello?

Answer 3

anyone there??

Answer 4

considering you posted this in the math section, excuse us for not giving an instantaneous answer. Don't be rude

Answer 5

im not rude i asked if anyone was there because it been a few minutes of no motion -_- I'm not rude

Answer 6

and its also posted in bio section. But theres more people online in this section so excuse me for needing help and being desperate

Answer 7

DNA polymerase then adds new, free nucleotides to the 3’ end of the newly-forming strand, elongating it in a 5’ to 3’ direction. However, DNA polymerase cannot begin the formation of this new chain on its own and can only add nucleotides to a pre-existing 3'-OH group.

idk if this helps you, I don't do science

Answer 8

so its C? i don't understand

Answer 9

My best guess would be C yes

Answer 10

@.Sam. what do you think?

Answer 11

hmmm

Answer 12

I know C could be right, but B might also be correct,

Answer 13

hm.. now i don't know which one xD

Answer 14

its deffinetly c

Answer 15

DNA polymerase are enzymes that assembles DNA molecules to create nucleotides
You can cross out the 3rd and 4th choices are for DNA ligase

Answer 16

I don't think C is right

Answer 17

No it could be B because if it's not replicating properly, then that means that it isn't copied properly, so the DNA sequence would change.

Answer 18

now I'm even more unsure i don't know cuz someone said c then sam said not c .. oy. xD

Answer 19

and now u say b

Answer 20

I'm with Sam. It's more logical to say that if something isn't copied right, then it's different from the original.

Answer 21

ok so then i will go with B. Ill tell u if i end up getting that one right if u want lol

Answer 22

Answer 23

I think this is called a mutation right? It exists, so the new strand of DNA can still bond with each other.

Answer 24

can i have help on another bio question? if ur not busy

Answer 25

How was (B) btw, was it right'??

Answer 26

i don't know yet i still have to finish the quiz before handing it in and seeing if its right

Answer 27

i have only 3 more questions left tho

Answer 28

@jgskater what?

Answer 29

no thx

Answer 30

why

Answer 31

Mason is preparing to present the results of a study he did to track the germination rates of bean seeds treated with growth hormones. He wants to show the different rates of growth as they progressed over time. Which of the following would be best for conveying growth rates over time?

Simple table
Line chart
Venn diagram
Pie chart

Answer 32

another question i have only this and 2 others which i was having a real hard time with

Answer 33

Okay, this question is obviously a line chart since time is a continuous x-variable on a graph, which would require a line.

A table would be for discrete x-variables.

Venn Diagram and Pie Charts only measure qualitative variable, not quantitative, and time and rate are quantitative.

Answer 34

yeah. Line chart makes sense. thanks (:

Answer 35

Which of the following best describes how the photosynthesis in grass cells is related to the cellular respiration in a cow's cells?

The carbon dioxide produced by photosynthesis in the grass cells is breathed and used to make ATP in the cow's cells during cellular respiration.

The carbon dioxide produced during the cow's cellular respiration is absorbed and used in the grass cells' photosynthesis to make ATP.

The energy stored in the grass cells' glucose during photosynthesis is eaten and used by the cow's cells to make ATP during cellular respiration.

The ATP produced during photosynthesis in the grass cells is eaten by the cow and stored as glucose during cellular respiration.

Answer 36

this is the second to last one i had a hard time with

Answer 37

Which organism most likely has 10% of the Sun's energy available for its use?

Insects
Hawk
Snake
Shrubs

ill post the pic

Answer 38

For the first question the answer is second choice. 'A' is wrong because complementary base pairing, not only they are able to form base pairs with each other, they must be complement to each other as well

Answer 39

so for the first is it B or C? cuz sam said B

Answer 40

I'm going with (B) as well. (C) has no logical back-up from anyone.

Answer 41

For the very last question, I'm going to make a guess that it's insects because it's the only one that receives energy from the tree directly, as opposed to the other types.

Answer 42

Hey @mhchen , plants do make ATP via light reaction ;) The ATPs are then used in Calvin cycle

Answer 43

Oh really? O_o....oh yeah...now I remember.

Answer 44

Let me revisit my answer then.

Answer 45

okay so the last one is insects?

Answer 46

ok

Answer 47

Actually, let Sam answer that Photosynthesis/Calvin Cycle question for you, I don't trust myself.

Answer 48

lol okay xD

Answer 49

The answer is D for the final question. Plants get around 10% on average from the sun's energy because there are a lot of factors that hinder the plants from gathering it, for example, stacked leaves, structure of chloroplasts

Answer 50

oh ok so shrubs. Thank you Sam

Answer 51

it wasn't shrubs but its okay

Answer 52

It wasn't? Plant's aren't 100% efficient alright I don't believe it

Answer 53

idk well it got marked wrong on the test

Answer 54

also the first question about photosynthesis, its a good thing i stuck with my gut and chose C instead of B because i got C right lol xD
