A woman gives birth to a son. What is the probability that her second child will be a girl

Answers

Answer 1

Answer: It would be 50% because having a son won't effect the probability of the next gender of the offspring. Unlike having to pick out two variables out of a bag, being pregnant is like having a trail but once you become pregnant again the trail restarts and does not use the previous data. You become a girl if you have 2 x chromosome and a boy by having one of x and one y. the odds are 50/50

List the steps that show how the sun. provides the energy for surface ocean currents

Answers

The heat moves in predictable ways, flowing from warmer objects to cooler ones, until both reach the same temperature. When air is in contact with the ocean at a different temperature than the sea surface, heat transfer by a conductor. The ocean absorbs and stores energy from the sun and when precipitation falls.

1. The sun’s thermal energy is exhibited from its surface traveling to the ocean floor in the day

2. As the heat energy is absorbed by the water, the currents move and rise as the ocean waters from the equator heads to the north phase of the planet.

3. And then the waters from the polar areas heads to the south, while ascending and gushing it becomes heated by the sun.

The sun’s gravity also affects this body of water. Since it has a much more stronger gravitation pull than of earth though its far away hence, high tide and low tide tendencies.

How does a deep ocean current compare to a surface one? A.
same salinity, but colder and less dense

B.
same temperature, but saltier and denser

C.
colder, saltier, and denser

D.
same density, but colder and saltier

Answers

the answer to your question is C- colder , saltier , and denser why because they don't have the same density level and deep ocean water is more dense than surface. and also Fromyour feet to your knees the water feels icy cold and from your knees to your head the water feelswarm. You probably wondered what causes this to happen. What you felt were warm surfacecurrents and cold deep currents. Changes in the density set these currents in motion. some ocean currents are set in motion by the wind other ocean currents are created by something you can't feel or see. Differences in density of water can also cause currents to form and move. Density is affected by temperature and salinity. i hoped i helped
