After the bank robbery, the very frightened people probably experienced increased activation of the sympathetic nervous system,

nata0808 [166]

The answer is Adrenaline

Adrenaline is a stress hormone secreted by the adrenal glands and some other neurons when a person is frightened, excited or generally in stress.

It prepares our body for it's 'fight or flight' mechanism and tightens muscles for exertion.

After a bank robbery, most people feel a rush of adrenaline.

(c) Based on the data in Table 1, describe why the dominant alleles for body color and wing shape are the alleles that produce a

Brrunno [24]

Answer:

Check the explanation

Explanation:

Consider the below table of F2 data of phenotypic flies: we can reconstruct the table as seen in the second attached image below:

From the above observations it is clear the Gray body long wings and Ebony body vestigial wings are the parental combinations and that the Gray body vestigial wings and Ebony body long wings are the recombinants.

Also the ratio indicates that Gray body is dominant over ebony body and that long wings is dominant over vestigial wings.

here the genes for the two characters have shown independent assortment which means that the genes are unlinked if located on the same chromosome or are located on different chromosomes.

Now F1 hybrid= GgLl (G for Grey and L for Long)

Cross between F1 hybrid and true breeding Gray vestigial (GGll)

GgLl x GG ll

Gametes-----------> GL Gl gL gl Gl

GL Gl gL gl

Gl GGLl GGll GgLl Ggll

(Gray long) (Gray vestigial) (gray Long) (Gray vestigial)

Therefore the probability of getting the flies with gray body vestigial wings= 2/4= 50%

b) The reason why the students obtained the above given F2 results involving a cross between true breeding Gray body and long wings with true breeding Ebony body and vestigial wings is that the genes for the two charcters asssort independently in F2 generation and that the genes are not linked as:

Parents------------------> GGLL x ggll

Gametes -----------------> GL gl

F1---------------------> GgLl (Gray long but in heterozous condition)

Now GgLl x GgLl

Gametes GL Gl gL gl GL Gl gL gl

Here gametes assorted independently and hence in F2 generation we got the above results (U can show the results in the form of punnett square.

Which statement best summarizes "Save the Coral Reefs”?Coral reefs are a very important component of the ocean’s ecosystem becau

cupoosta [38]

Answer;

-Coral reefs are a very important component of the ocean’s ecosystem because they support sea life, such as crabs and sea turtles. In fact, over four thousand species depend on the survival of the reefs, which are being destroyed by bleaching. More must be done immediately to save the reefs.

Explanation;

-Coral reefs are important for many different reasons aside from supposedly containing the most diverse ecosystems on the planet.

-They protect coastlines from the damaging effects of wave action and tropical storms ( they provide a buffer, protecting our coasts from waves, storms, and floods, helping to prevent loss of life, property damage, and erosion) and also provide habitats and shelter for many marine organisms.
