Answer:
React on cell surfaces, catalyze reactions.
Answer:
The solution is 0, 90 molal. See the explanation below, please
Explanation:
Molality is defined as moles of solute in 1 kg of solvent (1000 grams). The following three simple rule must be performed:
We calculate the weight of 1 mol of CaCl2
Weight Ca =40, 078 g
Weight Cl= 35, 453 g
Weight of 1 mol of CaCl2=40, 078g + 2x (35, 453g )= 110, 98g
110, 98 g ---1 mol
25 g---X= (25g x1 mol)/110, 98g= 0,23mol
250g solvent -----0,23 mol CaCl2 (the solute)
1000g solvent ----X = (1000g x0,23mol)/250g =0,90 mol solute
The solution is 0,90 molal
Species strategies to survive and successfully reproduce define three basic survivorship curves. <em>The survivorship curve </em><em>type III</em><em> is the one that best represents the Dandelion plants.</em>
------------------------------
According to the species strategies to survive, reproduce, and ensure their reproductive success, we can mention three basic curves,
<u>Type I.</u>
- Mortality often occurs at the end of the cycle, representing species with low mortality.
- Organisms exhibiting this type of survivorship curve have long life cycles and high probabilities to survive until they are old enough.
- These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success.
<u>Type II.</u>
- The probabilities of dying are equals all along the cycle, at any age interval.
- The number of dead individuals remains constant from the beginning to the end of the life cycle.
- These species have reduced offspring, and they ensure their reproductive success by providing some significant parental care.
<u>Type III.</u>
- Significant mortality during the early stages of life.
- Only a few individuals reach the later life stages, getting to survive their first period of life. Survivors usually have a long life.
- These species produce large offspring at the same time, but they provide little or no parental care.
- The reproductive success of these species depends on the number of descendants and not on the parenting time spent.
According to this information, and the characteristics of the <em>Dandelions, we might assume that this species is represented by type III curve.</em>

Answer:
<h2>411.86 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
m is the mass
v is the velocity
From the question we have
We have the final answer as
<h3>411.86 J</h3>
Hope this helps you
<span>Mutations sometimes improve the chances of survival for an animal.
But rather rarely. Advantageous mutations do happen, but neutral and harmful mutations are way more common.
