<span>B) Plant-based diets are usually lower in saturated fat and higher in fiber, which reduces risk of heart disease.
Saturated fats increase the risk for heart disease, so they should be kept lower. Fiber may help reduce overall calorie intake by keeping you full for longer. That way you maintain a healthy weight, which is important for</span><span> reducing </span>cancer<span> risk.</span>
En general las verduras son alimentos de bajo contenido calórico, por lo que se emplean mucho en dietas hipocalóricas.
Answer:
Option C - The sympatric salamander populations evolved their present body sizes after they became sympatric.
Explanation:
First, note the definitions of each terms.
1) Sympatric occurs when organisms especially of same species occurring in the same, or in overlapping territory, do not interbreed.
2) Allopatric occurs when organisms are NOT living in the same territory and thus unable to crossbreed.
On 1st QUESTION
The argument would be strengthened by the failure of P. cinereus and P. hoffmani to crossbreed making traits for body size to become distinct (dissimilar) in each specie.
On 2nd QUESTION
Definitely, salamanders species occurring in the territory, do not interbreed after they became sympatric, thus, making characters among same species to be increasingly different over generations.
Contractile proteins<span> generate force for muscle contraction. The two </span>contractile proteins<span> in myofibrils are actin (part of the thin filament) and myosin (part of the thick filament)</span>
Answer:
B. A cation
Explanation:
An atom is the smallest indivisible component of a matter including an element. An atom contains three particles called SUBATOMIC PARTICLES (PROTON AND NEITRON in the nucleus and ELECTRON surrounding the nucleus). The proton is positively charged while the electron is negatively charged.
The number of protons and electrons determine whether an atom will be postively charged (cation) or negatively charged (anion). In this question, an atom with 9 protons and 8 electrons will be A CATION because the protons (9) are more than the electrons (8), hence, making it a positively charged atom (cation).
N.B: The cation atom will have a +1 charge
