What effect does the heating of Earth have on air and water movement? PLEASE EXPLAIN

1 answer:

7 0

Heating of the Earth due to the Sun's rays causes convection currents of air upwards. The warm air moves upwards, while cool air from nearby regions fills in the lower areas.
<span>Heating of the Earth can cause warm water currents that flow from hot areas like near the equator and tropical areas, while cold water currents flow from the arctic and antarctic regions and the temperate regions. </span>

K. Which stage does the following occur

dangina [55]

The stages of the cell division at which each process occur would be as follows:

Chromatin condenses into chromosomes - prophase
chromosomes align in the center of the cell - metaphase
The longest part of the cell cycle - interphase
the nuclear envelope breaks - prophase
the cell is cleaved into two new daughter cells - cytokinesis
daughter chromosomes arrive at the poles - telophase

The cell cycle is characterized by two major events:

The interphase
The m phase

The cell prepares itself at the interphase by growing and increasing in volume, synthesizing DNA and proteins. Thus, the interphase takes a large chunk of the entire cycle.

The m phase represents mitosis. It is characterized by the following phases:

Prophase: nuclear envelope dissolves, chromatin condenses to become chromosomes
metaphase: chromosomes align at the center of the cell. Each chromosome gets engaged by spindles
anaphase: chromosomes are pulled apart by spindles. Sister chromatids start moving to opposite poles
telophase: migration to the pole is completed by chromatids

Once the chromatids reach poles, they decondense and a nuclear envelope emerges to surround them. The cytoplasm then divides to give rise to 2 daughter cells in a process known as cytokinesis.

Identify the stage of cellular respiration in which each of the following takes place,

Jlenok [28]

Produces 32 ATP molecules=oxidative phosphorilation

Creates four ATP molecules, but then gains overall only two=glycolysis

Gives off carbon dioxide=Kreb's cycle

Gives off water=electron transport chain

Produces two ATP molecules=Kreb's cycle

A corn plant known to be heterozygous at three loci is testcrossed. The progeny phenotypes and numbers are as follows:+ + + 455a

astraxan [27]

Answer:

The progeny phenotypes and numbers are as follows:

+ + + 455-------- parental

a b c 470-------- parental

+ b c 35----------- recombinant

a + + 33---------- recombinant

+ + c 37------------ recombinant

a b + 35--------------- recombinant

+ b + 460---------- parental

a + c 475----------- parental

Total 2,000

+ + + 455-------- parental

a b c 470-------- parental

+ b + 460---------- parental

a + c 475----------- parental

It is two point testcross

So the parental ++ (455+460); ac (470+475)------------------++/ac

Gene order is ------------- ++/ac

+ b c 35----------- recombinant

a + + 33---------- recombinant

+ + c 37------------ recombinant

a b + 35--------------- recombinant

sum of recombinants--------------140

Frequency of recombintion= recombinants/total x100

Map distances between a-c = (140/2000) x 100 = 7 mu

a------------------7 mu -----------------c
