<em><u>Air is less dense on a mountain top than at sea level.  </u></em>

<em><u>More force pushes on the air at the bottom of an air column.  </u></em>

<em><u>As you descend a mountain, air molecules are closer together. </u></em>

Answer: Option A, D & E

<u>Explanation:</u>

Air pressure means the effect of gravitational force acting on the surface area. Density is the measurement on the arrangement of the molecules. Altitude is the height above sea level. Air pressure decrease with altitude.

The altitude always determines the air pressure and density. As we get above the sea level the air is less dense lacking Oxygen. At higher altitude the air molecules spread more. Due to earth’s gravity the air is pushed towards the bottom of an air column.

You are doing lab work with a new species of beetle. You have isolated lines that breed true for either blue shells and long ant
Alex73 [517]

Answer:

33.3 cM

Explanation:

Parent 1: blue shell, long antenna : BBLL

Parent 2: green shell, short antenna : bbll

BBLL X bbll :

F1 : BbLl ( blue shell, long antenna )

BbLl X bbll :

BL/bl = 82 : Parental

bl/bl = 78 : Parental

Bl/bl = 37 : Recombinant

bL/bl = 43 : Recombinant

Total = 240

Recombination frequency = (Number of recombinants/ Total offspring)*100

= (80/240) * 100 = 33.33 %

Map distance = recombination frequency

Hence, map distance = 33.3 cM

Though plants, fungi, and prokaryotes all have cell walls, we place them in different taxa. Which of these observations comes cl
PtichkaEL [24]

Answer:

Due to other differences.

Explanation:

The plants, fungi, and prokaryotes all have cell walls, we place them in different taxa because of the other differences such as mobility, mode of nutrition etc. Plants and fungi are not mobile means can not move from one place to another whereas prokaryotes are mobile. Fungi and prokaryotes are heterotrophs means that feed on other organism whereas plants are autotrophs means make their own food. There is also difference in their cell wall i.e. the cell of plants is composed of cellulose, the cell wall of prokaryotes especially bacteria is composed of peptidoglycans and the cell wall of fungi is composed of chitin.

What does research say about the relationship between birth order, sibling spacing, and intelligence?
vesna_86 [32]

Answer:

"Birth order and sibling spacing are unrelated to a child's intelligence."

Explanation:

The theory, put forward by Robert Zajonc, a psychologist at the University of Michigan, holds, in brief, that the greater the number of children in a family and the shorter the time between their births, the lower will be the intelligence of the children, particularly those born later. A mother's genetics determines how clever her children are, according to researchers, and the father makes no difference. Women are more likely to transmit intelligence genes to their children because they are carried on the X chromosome and women have two of these, while men only have one.
