As an Astronaut goes out into space, her mass REMAINS THE SAME and her weight DECREASES.
When one travels away from the earth surface, one's mass remains the same but the weight decreases as the gravitation pull decreases.
The experience of weight on earth is as a result of the counteracting forces acting one's body and the ground. When one is in the space, this counteracting force is removed because the ground is no longer pushing back on one's body. Thus, one's weight will decrease in space because gravitational pull is lower above the earth's surface.
Answer:
With a cold comes inflammation of the structures around the vocal cords. With the inflammation comes swelling of those structures. Thicker vocal cords vibrate more slowly and give a lower pitch.
The phenotype is - 75 % red and 25 %brown.
The genotype is hRhR - 25%
hBkhR - 50%
hBrhBk - 25%.
<h3><u>Explanation:</u></h3>
The cross given here is a simple dominant - recessive relationship between the three types of alleles of hair colour. The genes of this characteristics are present in autosomes, so will be segregated equally among all the sexes of the offsprings.
Now the genotype of auburn and red with black mother is given. So during gametogenesis, the gametes from the parents will be
Father - hBr and hR
Mother - hBk and hR
So, the probable combinations are hBrhBk, hBrhR and hBkhR.
The frequency of the combinations are 25%, 25% and 50% respectively.
The phenotypic ratio will be red : brown as 3:1.
Things that occur in photosnythesis, would be water, heat, UV rays from the sun, humidity, and plants
hope this helps :P :)
