Answer:
R = 0 and no population growth.
Explanation:
Birth rate may be defined as the growth of individual per thousand and death rate determines the death of individual per thousand in a year. The birth and death changes the population dynamics.
The growth rate depends on both the factors that are birth rate and death rate. Here, the birth rate is balanced or equal that replace the offspring father. The change in the population growth is same and the birth and replacement almost cancel out each other. In this case, the birth rate is zero and population do not grow.
Thus, the answer is R = 0 and no population growth.
Answer:
It ocurred a selection by allopatric speciation
Explanation:
The allopatric speciation refers to the evolution in which the same specie starts developing different characteristics because of geographic barrers and this characteristics after some time generates two different specie.
It happens because usually according to the environment or the predators, species have to develop different adaptations so they can survive. In this case we have two different types of camouflage adaptations made by the salamanders acording to the conditions so for one specie it is better to camouflage from the predator mean while to the other is better to use lived colors to seem as it is a poisonous animal and in this way avoid the predators.
So you can see the same specie develop different strategies to survive because of a geographic separation, generating an allopatric speciation.
A and B is correct
Thanks! If helped give BRAINLIEST ;)
The earth was created by God in 7 days by forming it and calling it good on the 7th day of creation
Yes, sure!
1) Moving Water - Water, when running for a long period of time, can actually start to weather rocks.
2) <span>Ice wedging - Yep, this can cause rocks to weather as well. Water, when being constantly frozen and unfrozen weathers the rock due to the fact that water is able to expand.
</span>
3) Plant Roots - Ah, these little nutrient grabbers can certainly weather rocks over periods of time.
4) Winds - Winds can certainly physically weather the rocks, and it's probably the most common way they do.
<span>P.S. If this answer helped you, please, make sure to say "Thanks" just below my answer. It will help me a lot</span>
