A. Photosynthesis converts light energy into glucose, whose bonds have to be broken down in order to access the energy.
Answer:
1. polarity
2. hydrogen bonding
3. High heat capacity
4. Adhesion
5. polarity
6. surface tension
7. high heat vaporization
8. hydrogen bonds form a rigid and stable network
9. Water is a polar substance and fat is a nonpolar substance.
10. Cohesion
Explanation:
Water is a polar molecule that is held together by hydrogen bonds to form strong cohesive forces. This accounts for the surface tension in water. Surface tension is the force acting on water that it makes to behave like a stretched elastic skin.
The polarity of water accounts for the fact that it is found in several parts of the body where it largely plays the role of a polar solvent.
High heat capacity of water enables it to function well in the area of thermoregulation in the body. High heat vaporization accounts for the fact that water helps maintain extreme temperature changes in an area.
When in solid state, the hydrogen bonded network in water becomes rigid and forms a very stable network of water molecules. Being polar, water does not interact with fat because like dissolves like.
In plants, the attachment of water to plant roots is known as adhesion and is necessary for the capillary movement of nutrients to plants via the root.
Answer:
See details below
Explanation:
We know for sure that PK2 activates PK1 in a significantly signaling pathway. This is mainly because PK1 is permanently activated as a independent response which is observed in the status of PK2, by indicating that PK2 is fully activated downstream of PK1.
In the case that based on observation and experience, a setup were modified in a such a way PK1 was mutationally inactive and PK2 carried an activating mutation, we would not find any response observed since PK2 would not be able to activate PK1. The most importantly is that the logic is whether you discuss that PK1 activated PK2, I responded to this question part mainly based on this sequence.
It's B
Hope that helps, Good luck! (:
Answer:
Find the explanation below.
Explanation:
Culture refers to the way of life practiced by people, and their way of life includes their values, customs, language, beliefs, knowledge, and traditions. Culture would impact the demand for jobs in agriculture depending on the value a group of people places on agriculture. In most African cultures, for example, agriculture is highly valued and even some agricultural seasons are celebrated, an example is the New Yam festival celebrated by the Igbos in Nigeria. For such cultures, the demand for jobs in agriculture would be high because it is a treasured part of their lives.
However, for cultures that view agriculture as a strenuous activity, and place more emphasis on white-collar jobs, the demand for agricultural jobs in such climes would be low.
