Answer:
In a fruit fly experiment, grey body, normal winged (homozygous dominant) fruit flies were mated with black body, short winged (homozygous recessive) fruit flies. The F1 dihybrid females were then used in a test cross. If the genes are always linked and no crossing over occurs, what would be the predicted ratio in the F2 generation?
GG x bb = Gb, Gb, Gb and Gb F1 generation
grey body heterozygous offspring 4:0
Gb x Gb= GG, Gb, Gb, and bb F2 generation
3:1 three grey body fly and one black body fly
Explanation:
Answer:
Glucose, galactose, and fructose are common monosaccharides, whereas common disaccharides include lactose, maltose, and sucrose. Starch and glycogen, examples of polysaccharides, are the storage forms of glucose in plants and animals, respectively. The long polysaccharide chains may be branched or unbranched.
Explanation:
The barrier is cultural differences.
John, growing up in America learned that eye contact is a way of respect and to show you are paying attention.
Where Cho, growing up in Asia, many Asian counties don't have this "custom" to call it that.
- Thermosphere - Fourth layer of Earth's atmosphere.
- Aurora Borealis - Ionosphere layer of thermosphere.
- Large-scale air turbulence and mixing at this layer - Troposphere
- Stratosphere - Second lowest layer of Earth's atmosphere. No Air turbulence so airplanes fly in this layer.
- The coldest temperatures in the atmosphere occur at the junction- of Stratosphere and mesosphere
- Maximum ozone - Ozone layer in Stratosphere
Explanation:
Atmosphere is formed by mixing of gases. The layers of atmosphere is given below.
1. Troposphere -
- The first layer of the atmosphere.
- Weather occurs in this layer.
2.Stratosphere -
- The second layer of Earth's atmosphere.
- Contains Ozone layer.
3. Mesosphere -
- The third layer above the stratosphere.
- Coldest layer.
4. Thermosphere -
- The fourth layer of the atmosphere.
- Warmest layer.
- Ionosphere - lowest level of thermosphere above mesosphere.
- Aurora Borealis, Northern and Southern lights are seen in this layer.
- Exosphere - outermost layer of thermosphere.
- Satellites are in this layer.
- Outer space with no gravity.
