Okay First off what are the problems and what are the hardest ones?

It's not that hard if you use the pyramid in the corner.
The formulas are;
d/v = t
d/t = v
vt = d

For the first one they give you the distance (d) and the time (t). So, you do 27 (the distance) times 10 (the time) to get 270 m.

The second is set up the exact same way. distance x time. But you have to convert the hour to seconds. There are 60 seconds in 1 minute, and 60 minutes in an hour so do 60x60 and you get 3,600.
Do 33x3600 and it equals 118,800 m.

For this one you have to do

Think about the dna coding sequence of a gene. if an a were swapped for a t, what kind of mutation could it cause and why? think

Hi, 

I think the answer you're looking for is already in the question you submitted. However, I disagree that a frameshift could result from the mutation because frameshifts would only happen if there were insertions or deletions in the sequence. For your question, this is an example of a simple point mutation/nucleotide base substitution, and would only result to either a missense or a nonsense mutation. Depending on the bases flanking your mutation, this results to transcribing a different sequence of RNA leading to translating either a different amino acid or a stop codon.

What part of the body uses active transport to take up nutrients after concentration has reached equilibrium
jekas [21]

The villi of the small intestine use active transport to take up nutrients after concentration has reached equilibrium.

<h3>What is Active transport?</h3>

Active transport may be defined as the process that occurs against the concentration gradient and is mediated by carrier proteins. Metabolic energy is used to move ions or molecules against a concentration gradient.

During the process of digestion, the villi in the small intestine enthrall the soluble nutrients gradually. Over time, the concentration of nutrients in the villi acquires an equilibrium with the concentration in the gut. Until here, the nutrient uptake is carried by the process of passive diffusion.

But after attaining the equilibrium, the nutrient uptake is carried by the process of active transport.

The complete question is as follows:

What part of the body uses active transport to take up nutrients after concentration has reached equilibrium?

  • Lungs
  • Stomach
  • Small intestine
  • Liver

Therefore, the correct option for this question is C, i.e. small intestine.

If a car weighing 1500 kg and a truck weighing 4,000 kg are both traveling at 55 mph, which one will take more force to stop?
Zarrin [17]
The Truck will take more force to stop the truck  moving at a speed of 55mph weighing 4000kg has alot more momentum and will require a force equal to its speed and mass to stop it therefore the truck is the most obvious answer hope this helped bud
