Two parents, both with brown eyes, have four children. One child has brown eyes, like his parents, but the other three all have blue eyes. One of the children has been learning about genetics in science class and knows that brown eyes are dominant to blue eyes in humans. The student developed the following model of a Punnett square to predict the genotypes of his parents and his siblings.

Based on his model, the student claims that only one of the four children should have blue eyes. Which of the following explanations best describes why the Punnett square does not model the traits in the student’s family? (DOK 3)

Answer:

Punnett squares are not exact answers, they are only used to predict traits.

A.

The student is forgetting that a Punnett square is used to predict the outcomes of a genetic cross. The actual results do not always match up to the predicted outcomes.

Metamorphic rocks are a bit harder to identify because they can share traits with the other rock types. Again, thinking about the formation process can help. Metamorphic rocks have been heated and squashed. This can lead the minerals in them to line up, creating ribbon-like layers called bands. These rocks are called foliated metamorphic rocks. You can see these bands in gneiss. If a metamorphic rock has fossils, you know it was formed from a sedimentary rock. Because of the heat and pressure, the fossil will be hard to recognize and out of shape.

Which of the following best describes foliated metamorphic rocks?

A
There are easily recognizable fossils.

B
The rock has ribbon-like layers of bands.

C
They have crystals like igneous rocks.

D
Different sized sediments can be see

Why is it difficult to know the impacts of deep sea mining?
O It has never been tried successfully, so we don't know exactly how it can be done.
Olt is only done in environmentally sensitive areas, where the organisms are being harmed in many ways already, and it is difficult to know the effects of mining.
We know relatively little about deep sea ecosystems, making it harder to assess the impact of mining.
O Most countries have laws against it, so the impacts have not been tested.

Which statement best summarizes how the light-dependent reactions and light-independent reactions (Calvin cycle) work together during photosynthesis
The light-dependent reactions capture energy and the light-independent reactions use that energy to make glucose
The light-dependent reactions capture energy and the light-independent reactions use that energy to make ATP
The light-dependent reactions take in glucose (food energy) and the light-independent reactions use the glucose to make ATP
The light-dependent reactions capture bees and the light-independent reactions blend those bees up into golden cheddar mac and cheese... watch
out for the stingers though
