<span>Potassium is actively transported into and out of the vacuoles in the guard cells.
There are different kind of potassium transport channels (KAT1, KAT2) that transport K+ inside and outside the vacuole of the guard cell, by the use of ATP (energy) and H+.</span>
Answer:
Examples of positive symptoms are hallucinations, delusions, and repeated movements that are hardly to control or movement disorder.
Explanation:
Schizophrenia is severe mental disorder, which usually starts between the age of 16 - 30. This disorder affects the way people think, behave and feel.
Generally, its symptoms can be grouped into three, which are
* Positive symptom .... This is when people are manifesting psychotic behaviors which are never seen in healthy people.
* Negative symptom..... Its can be related to normal emotions. Examples are reduced feeling, speaking and expression e.g facial expression.
* Cognitive symptom..... This include having trouble in paying attention and trouble with memory.
They have uncoiled to form long, thin strands.
Interphase is made up of G1, S, and G2 phases where S is the synthesis phase and G2 prepares the cell for mitosis/meiosis.
Answer:
Row 1
T-tubule
Dihydropyridine (DHP) receptors of the transverse tubule membrane play two roles in excitation-contraction coupling in skeletal muscle: (a) they function as the voltage sensor which undergoes fast transition to control release of calcium from sarcoplasmic reticulum, and (b) they provide the conducting unit of a slowly ...
Row 2
Sarcolemma
Ryanodine receptors (RyRs) are located in the sarcoplasmic/endoplasmic reticulum membrane and are responsible for the release of Ca2+ from intracellular stores during excitation-contraction coupling in both cardiac and skeletal muscle.
Answer:
1. Fluorine (7 electrons) => c. steals 1 electron
2. Calcium (2 electrons) => a. gives away 2 electrons
3. Oxygen (6 electrons) => d. steals 2 electrons
4. Lithium (1 electron) => e. gives away 1 electron
5. Xenon (8 electrons) => b. neither gives away nor steals any electron
Explanation:
Given the following valence electrons of the atoms listed above, each atom can be matched to its corresponding number of electrons it can steal or give away as they form bonds and attain a stable state:
1. Fluorine (7 electrons) => this will steal 1 electron from another atom to attain a stable state when it comes to make the number of electrons 8.
2. Calcium with 2 valence electrons, will give away this 2 electrons in its outer shell to be stable and form bond with another atom that will accept these 2 electrons.
3. Oxygen with 2 valence electrons, will steal 2 electrons to make the electrons in its outer shell 8, as it bonds with another atom to become stable.
4. Lithium will give away 1 electron to become stable when it combines.
5. Xenon with 8 electrons in its outer shell is in a stable state and kind of inert. It doesn't need to receive or steal any electron from or to any other atom in this state.
