Answer:
Mitochondria.
Explanation:
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder in which the neuron died due to mutation in superoxide dismutase 1 gene. This disease is also known as Lou Gehrig's disease.
Mitochondria structure is disorganized in ALS. The ubiquitin protein mutation leads to the malfunctioning of mitochondria and misfolded proteins are made in the mitochondria.
Thus, the correct answer is option (a).
Answer:
WHO is involved: (major protein players)
WHAT is being completed:
WHEN does it occur in the cycle of the cell:
WHERE does it occur in prokaryotes or eukaryotes:
WHY does replication happen:
Explanation:
These are the 5 W's for any situation in life but directly applied to biology and DNA these are the exact and specific W's
Answer:
C
Explanation:
They all live in the water
<h2>Transportation across the membrane</h2>
Explanation:
(a) Simple diffusion; Faciliated diffusion-Directions in which two transported solutes move
- In simple diffusion diffusion of non polar compounds across the membrane and along the concentration gradient without the involvement of protein whereas in case of facilitated diffusion membrane transport proteins that facilitate movement pf molecules across the membrane down its concentration gradient
- Both the diffusions does not require energy
(b) Facilitated diffusion; active transport-Direction the solute moves relative to its concentration gradient
- In facilitated diffusion membrane transport proteins that facilitate movement of molecules across the membrane down its concentration gradient without the expenditure of energy
- Active transport drives transportation of solute against the concentration gradient across the membrane
(c) Simple diffusion; Active transport-Directions in which two transported solutes move and Direction the solute moves relative to its concentration gradient
- In simple diffusion diffusion of non polar compouds across the membrane and along the concentration gradient without the involvement of protein and energy
- Active transport drives transportation of solute against the concentration gradient across the membrane;secondary active transporters coupled with transportation of two solute molecules
(d) Direct active transport; Indirect active transport-Direction the solute moves relative to its concentration gradient or its electrochemical potential
- Direct active transport use direct energy such as ATP hydrolysis,oxidation and sunlight energy
- Indirect active transport use indirect energy such as chemical gradient,electrochemical gradient established by direct active transporters;one solute moves along the concentration gradient while other moves against the concentration gradient
(e) Symport; Antiport-Direction in which two transported solutes move
- In symport both the solute molecules move in same direction;coupled with primary active transport(direct transport)
- In antiport both the solutes moves in opposite direction;coupled with secondary active transport(indirect transport)
(f) Uniport; coupled transport-Directions in which two transported solutes move
- Uniport is the transport of single solute across the membrane
- Coupled transport is the transport of two solute molecules across the membrane;it may be symport or antiport
(g) P-type ATPase; V-type ATPase-Kinetics of solute transport
- P-type ATPase always transport cations and undergoes phosphorylation
- V-type ATPase(here V stands for vacuole) transport protons and no phosphorylation occurs;catalytic activity is not reversible
- Both are types of primary active transporters
A person who has cerebrospinal fluid draining from the ear probably has a fracture of the temporal bone.
<h3>What is Cerebrospinal Fluid?</h3>
All animals have cerebrospinal fluid (CSF), a transparent, colorless bodily fluid that is present in the tissue that covers their brains and spinal cords.
Specialized ependymal cells in the choroid plexus of the brain's ventricles create CSF, which is then absorbed in arachnoid granulations. About 125 mL of CSF are present at any given moment, and 500 mL are produced daily. The CSF protects the brain inside the skull mechanically and immunologically by acting as a shock absorber, cushion, or buffer. The cerebral autoregulation of cerebral blood flow is another essential role played by CSF.
The ventricular system and subarachnoid space, which are located surrounding and inside the brain and spinal cord, respectively, are occupied by CSF.
