LESSON 4.2 Review
Andrews [41]

Answer:

Energy is said to flow in a "one-way stream" through an ecosystem. In your own words, describe what that means. Energy is not recycled. Energy enters an ecosystem and flows through a food chain, but it is not reused, it is lost as heat.

Hope the answer helps:)

Which of the following will allow for the greatest reduction in an individual’s carbon footprint?
goldfiish [28.3K]

The carbon footprint can be decreased by a great amount if the incandescent bulbs are replaced with the compact fluorescent bulbs. The compact fluorescent bulbs uses approximately seventy five percent less energy than the incandescent bulbs as they do not use heating mechanism to light. This leads  to less emission of the green house gases and thereby reducing the carbon footprint.

Hence, the correct answer is 'option a - replacing incandescent bulbs with compact fluorescent bulbs'.

In humans, blue eyes are caused by a recessive allele ("b") that dilutes pigment production. BB and Bb individuals have brown ey
saveliy_v [14]

Answer:

Probability that the son will be:

color-blind = 1/2

blue eyed = 1/8

blue eyed and color-blind = 1/16

Explanation:

Mother : BbXcX

Father : BbXY

Colorblindness is X linked recessive trait hence will be caused when the son has XcY genotype.

XcX   X    XY :

     Xc    X

X  XcX  XX

Y   XcY  XY

Half of the sons will have normal vision and other half will be colorblind hence, there is 1/2 probability that the son will be colorblind.

Eye color is autosomal trait and blue color will be produced when the child has bb genotype.

Bb     X    Bb  :

   B    b

B  BB  Bb

b  Bb   bb

1/4 of the children will have blue eyes. Since half of the children are expected to be males, 1/4 * 1/2 = 1/8 sons are expected to have blue eyes.

Probability of a son being blue eyed and color blind will be :

1/8 * 1/2 = 1/16

Nata [24]

Answer;

-The third stage fever

Explanation;

-Fever, also referred to as pyrexia and febrile response, involves having a temperature above the normal range (above 37.5 or 38.3 °C)  due to an increase in the body's temperature set-point (36.5–37.5 °C). This increase in set-point temperature triggers increased muscle contractions and causes a feeling of cold.

-The first stage of a fever is marked by headache and body aches, the second stage is marked by the chills, and the  third stage is the flush state. The fourth stage is defervescence.
