Answer:

Their survival is correlated to water clarity because kelp, the main food of otters' prey (sea urchins), needs clear water to thrive.

Explanation:

Otters are extremely important organisms, also known as "<em>keystone</em>" species. They keep aquatic ecosystems healthy because they control other populations such as sea urchin populations that consume kelp, sometimes in excess.

For this reason, otters prefer inhabiting near the kelp, which generally grows in clear waters near shores. They also prey on crabs, marine snails, squid, etc. as they possess the ability to dive as deep as 250 feet.

Therefore, their survival is correlated to water clarity because kelp, the main food of otters' prey (sea urchins), needs clear water to thrive.

The fraction of offspring with black coat color and straight fur is 9/16.

Explanation:

Information given:

black coat colour and straight fur - dominant genotype BBCC, BbCc

yellow coat colour and curly fur - recessive genotype bbcc

Both the traits are independently assorted. The fur colour and fur type is not present on the same chromosome and are not sex linked.

The genotype of the parents are:

BbCc X BbCc

Punnet square shows:

BC Bc bC bc

BC BBCC BBCc BbCC BbCc

Bc BBCc BBcc BbCc Bbcc

bC BbCC BbCc bbCC bbCc

bc BbCc Bbcc bbCc bbcc

9 BLACK STRAIGHT

3 BLACK CURLY

3 YELLOW STRAIGHT

1 YELLOW CURLY

9/16 is the fraction of progeny to be black coat colour and straight fur.

Benjamina started her walk from the front door of her ground floor apartment. She walked 6 meters to the corner of the building

gizmo_the_mogwai [7]

According to given information,
Distance = 6 + 10 = 16 m
Displacement = 4 m

So, Distance - Displacement = 16 - 4 = 12 m

So, your final answer is 12 m.

Hope this helps!

To solve a problem using the equation for Kepler’s third law, Enrico must convert the average distance of Mars from the Sun from

vovikov84 [41]

Answer:Enrico must multiply the distance of mars from sun (meters) with the $6.6844\times 10^{-12}$ to convert the distance in astronomical units.

Explanation:

1 astronomical unit = $1.496\times 10^{11} m$

$1m=\frac{1}{1.496\times 10^{11} } AU=6.6844\times 10^{-12} AU$

Let the distance between the sun and Mars be Y( meters)

Distance in AU= $Y\times 6.6844\times 10^{-12} AU$

Enrico must multiply the distance of mars from sun (meters) with the $6.6844\times 10^{-12}$ to convert the distance in astronomical units.
