Vesnalui [34]2 years ago

Answer:

B. False

Explanation:

Life history characteristics and survivorship patterns within a species are pre-set but may be changed according to the changes in environmental conditions needed for growth and reproduction. Allocation of energy to reproduction or other processes varies according to food availability, temperature, rainfall, etc.  

Abundant resource availability favors the production of a large number of smaller offspring while limited resources make a population to produce a small number of larger progeny to increase the survival rate.  

Example: Clutch size in birds is adjusted to obtain the maximum survival of progeny.

The decision to visit planets other than Earth is not supported by everyone. What would be a good argument against sending human
Ann [662]

Answer:

Sending humans to other planets may cause danger. We dont fully know what these planets are capable of doing. If there is such a thing as life on other planets then we still dont know weather or not life there is friendly or not. They could be harmful, because just as we dont know know exactly who or what they are, they dont know who or what they are either, so its a high chance they may want to defend themselves.

Which is a limitation of a scientific model?
iren [92.7K]

Answer:

The correct option is<em> D)  Models are not the "real thing" so it will never correctly represent the system in all respects.</em>

Explanation:

Scientific modelling can be described as a representation of the scientific theories or concepts in a way that can be better understood. Scientific models makes it easier to understand what physical, chemical or mechanical activity is taking place. Even mathematical representation comes under scientific modelling.

As models are not the real, hence they cannot be considered to be perfectly accurate. A model can never mark up to the complexity of nature.

imagine a model of a cell shaped like a cube.Calculate the ratio of surface area to volume for a cell model measures 3 cm on eac
Svet_ta [14]
Smaller cube (1 cm X 1 cm X 1 cm) 

<span>The surface area of one side = 1 cm X 1 cm = 1 <span>cm2</span></span>

 

<span>There are 6 sides, total SA = 6 X 1 <span>cm2</span> = 6 <span>cm2</span></span>

 

<span>Volume = 1 cm X 1 cm X 1 cm = 1 cubic cm (1 <span>cm3</span>)</span>

<span>Surface to Volume Ratio = 6 <span>cm2</span>/1 <span>cm3</span> = 6 <span>cm2/cm3</span></span>


Larger cube (6 cm X 6 cm X 6 cm) 

<span>The surface area of one side = 6 cm X 6 cm = 36 <span>cm2</span></span>

 

<span>There are 6 sides, the total SA = 6 X 36 <span>cm2</span> = 216 <span>cm2</span></span>

 

<span>Volume = 6 cm X 6 cm X 6 cm = 216 <span>cm3</span></span>

 

<span>Surface to Volume Ratio = 216 <span>cm2</span>/216 <span>cm3</span> = 1 <span>cm2/cm3</span></span>

Do you think that Earth is overpopulated by
lara [203]

Answer:

i think less is more

Explanation:

let me explain so i think less would be better because then you wound have as many people that are homeless or refugees we all wish refugees could find safe homes but for all of them that just isn't possible.Then again i don't think that you should resort to genocide when trying to maintain a smaller population.Though one could argue the opposite.

(you can come to your own conclusion this is just my opinion)
