Answer:
The metabolic rate per gram of tissue is greater in large endotherms than in small endotherms.
Explanation:
Metabolic rate is a measurement of metabolism in animals: how much energy is used per time. Energy used on a daily level is described as basal metabolic rate. Among both, endotherms (maintain their own heat) and ectoterms (depend on external heat) metabolic rate depends on animal's activity, active animals have higher metabolic rate.
Metabolic rate in ectoterms vary with temperature, while in endoterms it does not.
Answer:
Agarose gel or Pores in the gel
Explanation:
This question could have multiple answers because the gel has pores in it that allow smaller fragments of DNA to move faster through the pores because they're not getting stuck in the gel. Larger fragments of DNA get stuck in the gel as they try to fit through the large pores.
So, you could either say the agarose gel itslef or you could say the pores in the agarose gel allow the molecules to move at different rates.
Answer:
1.33 m/s
Explanation:
The formula for Kinetic Energy is given as:
![K.E=\frac{1}{2} mv^{2} \\](https://tex.z-dn.net/?f=K.E%3D%5Cfrac%7B1%7D%7B2%7D%20mv%5E%7B2%7D%20%5C%5C)
Where, m is the mass and v is the velocity of the object. In order to tell how fast is the object moving we need to calculate its velocity.
Re-arranging the above equation and isolating v, we get
![2 K.E = mv^{2}\\\\v^{2} = \frac{2 K.E}{m}](https://tex.z-dn.net/?f=2%20K.E%20%3D%20mv%5E%7B2%7D%5C%5C%5C%5Cv%5E%7B2%7D%20%3D%20%5Cfrac%7B2%20K.E%7D%7Bm%7D)
Putting values in this equation, we get:
![v^{2}=\frac{2 \times 32}{36}\\\\ v^{2}=\frac{16}{9}\\\\ v=\frac{4}{3}\\\\ v=1.33](https://tex.z-dn.net/?f=v%5E%7B2%7D%3D%5Cfrac%7B2%20%5Ctimes%2032%7D%7B36%7D%5C%5C%5C%5C%20v%5E%7B2%7D%3D%5Cfrac%7B16%7D%7B9%7D%5C%5C%5C%5C%20v%3D%5Cfrac%7B4%7D%7B3%7D%5C%5C%5C%5C%20%20v%3D1.33)
Thus, the object is moving with a velocity of 1.33 m/s
These are examples of interjection. Interjection is a part
of speech that denotes feeling and emotion. For instance, “that hurts!”, “cool!”
and “beautiful!”. If noticed, these are accompanied by an exclamation point
which highlight the authors point of emotion with respect to their statement.
