Answer:
0.42mole
Explanation:
Given parameters:
Number of atoms of titanium = 2.5 x 10²³atoms
Unknown:
Number of moles = ?
Solution:
To solve this problem, we must understand that a mole of any substance contains the Avogadro's number of particles.
6.02 x 10²³ atoms makes up 1 mole of an atom
2.5 x 10²³ atoms will contain 
= 0.42mole
Answer:
Explanation:Given;
applied force, F = 8000 N
time of force application, t = 15 s
Work done is given as the product of force and displacement. Since the car is unable to move, then the displacement is zero and the work done is zero.
Work done = Force x displacement
Work done = 8000 N x 0
Work done = 0
Therefore, the work done is zero.
They are life cycle differences that protect the offspring and help them to survive. The correct option is C.
<h3>Life cycle adaption</h3>
Some organisms have life cycle features that ensure that their population is perpetuated in subsequent generations.
Such features include ensuring that propagules are only released when they are mature and making sure that eggs are hatched and offspring become viable before they are allowed to move to the environment.
These actions will make sure that the propagules of offspring have what it takes to survive in their new environment.
In other words, these life cycle features are embedded in the genome of organisms as a way to survive the environment.
Thus, the features of the Himalayan balsam plant and that of the Surinam toad are more or less targeted toward the same thing - the survival of their offspring.
