How are whales different from fish

Biology
1 answer:
irinina [24]3 years ago
6 0

Whales have horizontally positioned tales opposed to fish and they swim in an up and down type of motion to move, where as fish are the exact opposite flexing and turning their body left and right with their vertical tale to move.

Whales have bigger mouths to eat large schools of krill (their main source of food)

And also, whales are mammals, and breathe with their lungs, whereas fish use gills to breathe underwater. I hope this helped! Please mark Brainliest!

The frequency of sickle-cell anemia, an autosomal recessive condition, is 0.007. Assuming that the population is in H-W equilibr
damaskus [11]

Answer:

The correct answer is - 0.084

Explanation:

Sickle cell anemia is a autsmal recessive blood disorder of RBCs where RBC shape altered to the sickle shape or cresecent moon that obstruct and damage the veins and artries.

Normal allele is represented by - HbA - p

sickel cell allele is represented by - HbS - q

genotype frequency of normal allele HbA in the population = p2

genptype frequency of HbAHbS in the population = 2pq

genotype frequency of autosomal recessive HbS = q2 = 0.007 (given)

So, the allelic frequency of the recessive allele =

q =  √ 0.007 = 0.08366 or 0.084

A hairdryer uses 1500 J of electrical energy in 1 second. The hairdryer changes 1300 J of this to useful thermal energy in 1 sec
Katarina [22]

200 J of energy is wasted by the hair dryer.

Steps

  • The hairdryer is provided with 1500 J of electrical energy per second
  • Of this 1500 J, 1300 J of energy is actually used and converted to useful thermal energy per second
  • The remaining energy, 1500 - 1300 = 200 J is dissipated

Dissipated energy

  • The energy that is not efficiently transported or changed is wasted energy.
  • We cannot create or destroy energy.
  • An employable type of energy is created through transformation.
  • Only a portion of energy that is changed or transferred can be done so in a way that is helpful.

Thus, 200 J of energy is wasted by the hair dryer.

Otrada [13]

Answer: An essay is a common type of academic writing that you'll likely be asked to do in multiple classes. Before you start writing your essay, make sure you understand the details of the assignment so that you know how to approach the essay and what your focus should be. Once you've chosen a topic, do some research and narrow down the main argument(s) you'd like to make. From there, you'll need to write an outline and flesh out your essay, which should consist of an introduction, body, and conclusion. After your essay is drafted, spend some time revising it to ensure your writing is as strong as possible.
