Answer:
Energy retained at consumer level 1 - 100 units
Energy retained at consumer level 2 - 10 units
Energy retained at consumer level 3 - 1 units
Explanation:
The total units of energy lies at the producer level of the energy pyramid.
Now at each trophic level only 10% of the energy of its previous level is passed on which means at
Consumer level 1 -
energy retained % energy at producer level
units
Like wise -
Energy retained at consumer level 2 -
units
Energy retained at consumer level 3 -
units
Thus,
Energy retained at consumer level 1 - units
Energy retained at consumer level 2 - units
Energy retained at consumer level 3 - units

X-linked recessive disorders require two affected (recessive) alleles Xb to express in the female, but requires (the) only one in the male.
Therefore there are no male carriers. A normal male has the XB allele, and the affected male has the Xb allele.
A female either has 2 XB alleles, in which case she is normal and not a carrier.
If she has XBXb alleles, then she is a carrier, but phenotype is normal.
If she has XbXb alleles, she will exhibit colour-blindness.
Since woman's father has colour-blindness and she has normal vision, she is a carrier, because she has XBXb alleles.
Her husband has normal vision, so he has (one) XB allele.
Here's the Punnett square
Mother XB (father)
XB XBXB (normal vision)
Xb XBXb (carrier)
We see that the XbXb (colour-blindness) case is missing, so the phenotype colour-blind is not expected (unless other medical conditions are present)
Answer:
All the planets besides Earth lack a breathable atmosphere for terrestrial beings, but also, many of them are too hot or too cold to sustain life. A “habitable zone” which exists within every system of planets orbiting a star. Those planets that are too close to their sun are molten and toxic, while those that are too far outside it are icy and frozen.
But at the same time, forces other than position relative to our Sun can affect surface temperatures. For example, some planets are tidally locked, which means that they have one of their sides constantly facing towards the Sun. Others are warmed by internal geological forces and achieve some warmth that does not depend on exposure to the Sun’s rays.
