Answer:
Lizards with this adaptation were more likely to escape from predators
Explanation:
Rotational symmetry is radial symmetry which means that the shape is the same after several rotations. In five-fold rotational symmetry<span> the number of distinct orientations in which the object looks the same is five. </span>
Living organisms whose shapes have five-fold rotational symmetry are sea stars (starfish) and sea urchin. They <span>can be mapped onto itself through rotation about a central point by an angle of 2π/5. </span>
Answer:
Cool water at the surface traps nutrients deep in the lake to provide food during the winter.
Explanation:
During winter, <u>ice forms on the surface of the lake</u> when the temperature drops below 4 degrees Celsius. However, the <u>water below remains warm</u> because the ice layer on top also acts as insulation of heat transfer in case of further temperature drops. Further, ice formation <u>retains/seals off</u> nutrients and gases flow below the ice sheet. The amount of nutrients is sufficient for phytoplankton activity during light hours (there is no complete darkness even after thick ice sheet is formed). Resultantly, the <u>photosynthesis</u> produces <u>oxygen and food</u> for aquatic organsism within the lake environment and support their <u>survival during winter season</u>.
Because particles move randomly, molecules tend to move
across the membrane in both directions. Yes, the model indicates that the molecules are moving
in equal amounts in both directions. This calld the state of equilibrium where
the forward and backward movements are equal hence the net movement is equal to zero
Answer:
1)Manganese (Mn)
2)Sulfur(S)
Explanation:
Atoms of which element contain 25 protons?
It is Manganese.
The atomic number of an element is the number of proton in the nucleous of an atom of the element. Here proton= 25= atomic number.
The number of proton helps to identify the particular element. In the modern periodic table, the elements are arrange base on how the atomic number is increasing. Then Manganese has atomic number of 25.
✓Which element has an atomic number of 16?
It is Sulfur, as explained earlier, the number of pron in the atom of the sulfur element is 16.
