There is a 3/4 chance their offspring will be black. If you make a Punnett's (I hope that's how you spell it) square then you will find that one offspring will be homozygous for black hair, two will be heterozygous with black hair, and one will be homozygous with brown hair. Therefore, there's a 3/4 chance the offspring will have black hair. Hope this helped!
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
Answer:
6.) larger diameter of stomatal pores
A) Increased transpiration pull
1.) thicker film of water on surface of mesophyll cells
2.) higher relative humidity in air around leaf
B) decreases transpiration pull
3.) less curvature of water surface on mesophyll cell walls
4.) lower rate of water evaporation from surface of mesophyll cells.
5.) larger air space in leaf interior
C) has no effect on transpirational pull.
Explanation:
- Transpiration primarily occurs through stomatal openings in the leaves. Increasing the diameter or size of these opening would ultimately increase the amount of water escaping from them and therefore, increase the transpiration rate.
- Higher humidity in the air entails the presence of greater number of water vapours in the atmosphere. Since osmotic pressure plays a major role in transpiration, therefore, this decreases the rate of transpiration.
Cells need oxygen to break glucose to produce Energy required for doing several functions.
