Which is not a function of cholesterol within the cell membrane?
Reduces permeability to some solutes
Reduces membrane fluidity
Prevents crystallisation of the membrane at low temperatures
Transports molecules across the cell membrane
Answers
Answer:
c
Explanation:
The function of cholesterol within the cell membrane maybe be many, but does not include the reduction in membrane fluidity .
The steric structure of the cholesterol in the cell membrane is such that:
it prevents freezing of the membrane when the temperature gets lowIt limits the permeability of some materialsit makes the membrane more fluid and stableit helps take up cholesterol from the surrounding environment into the cell, hence, helps with the transport of molecules.The correct answer as to which is not a function of cholesterol within the cell membrane would, therefore, be that it reduces membrane fluidity.

Going into the final stage of aerobic respiration, how many energy molecules have been created from one glucose molecule?.
Answers
4 molecules of ATP have been created from one glucose molecule going into the final stage of aerobic respiration.
The three steps of aerobic respiration utilize glucose to make ATP. The glycolytic pathway produces two ATP molecules, while the tricarboxylic acid cycle produces another two. Hence, 4 ATP molecules are produced going to the final stage of aerobic respiration.
The electron transport chain is the ultimate stage of aerobic respiration. A total of 32 extra ATP molecules are generated by electron transport from NADH and FADH2 molecules produced by glycolysis, pyruvate transformation, and the Krebs cycle. As a result, during cellular respiration, up to 36 molecules of ATP may be created from only one molecule of glucose.

Here, study examined the immunogenicity and anamnestic protective effectiveness of INO-4800, a SARS-CoV-2 spike DNA vaccine that is currently undergoing clinical trials, in rhesus macaques. Immunization with INO-4800 stimulated T cell responses and produced antibodies that bind to spike antigen and RBD with ADCP and ADCD activity. The SARS-CoV-2 pseudotypes D614 and G614 were both neutralized by animal serum. Animals exposed to SARS-CoV-2 several months after immunization demonstrated a quick recall of anti-SARS-CoV-2 spike protein T cell and neutralizing antibody responses.Learn more about the SARS-CoV-2 with the help of the given link:

5 osmosis
Answers
Facilitated diffusion, osmosis and diffusion are examples of passive transport
WHAT IS PASSIVE TRANSPORT?
Passive transport is a kind of transport that does not require the input of energy (ATP). The examples of passive transport there is are as follows:Osmosis: Osmosis is the movement of water from a region of high concentration to a region of low concentration via a semipermeable membrane. Since, water is moving down a concentration gradient, no energy is required. Diffusion: This is the movement of molecules from a region of higher concentration to a region of lower concentration. No energy is required for this to occur as well. Facilitated diffusion: Facilitated diffusion is a kind of diffusion that occurs with the aid of transport proteins. It also does not require energy input.Therefore, facilitated diffusion, osmosis and diffusion are examples of passive transport.

prenatal kynurenine exposure in rats: age-dependent changes in nmda receptor expression and conditioned fear responding
Answers
Rationale: Levels of kynurenic acid (KYNA), an endogenous terrible modulator of alpha 7 nicotinic acetylcholine receptors (α7nAChRs) and antagonist at glutamatergic N-methyl-D-aspartate receptors (NMDARs), are expanded in the talent of patients with schizophrenia (SZ). In rats, dietary exposure to KYNA's immediately precursor kynurenine at some stage in the final week of gestation produces neurochemical and cognitive deficits in maturity that resemble these viewed in patients with SZ.
Objectives: The current experiments examined whether prenatal kynurenine publicity results in age-dependent adjustments in the kynurenine pathway (KP), expression of selected receptors, and cognitive function.
Methods: Pregnant dams have been fed unadulterated mash (progeny = ECON) or mash containing kynurenine (100 mg/day; progeny = EKYN) from embryonic day (ED) 15 to 22. Male offspring have been assessed as juveniles, i.e., prior to puberty (postnatal day [PD] 32), or as adults (PD70) for intelligence KYNA levels, α7nAChR and NMDAR gene expression, and performance on a hint worry conditioning (TFC) task.
Results: KYNA degrees have been similar between juvenile ECON and EKYN rats, whereas EKYN adults exhibited a ~3-fold amplify in intelligence KYNA relative to ECONs. NR2A expression was constantly reduced (30-40 %) in EKYN rats at each ages. Compared to ECON adults, there used to be a 50 % reduction in NR1, and a vogue toward diminished α7nAChR expression, in grownup EKYN rats. Surprisingly, juvenile EKYN rats performed considerably higher in the TFC paradigm than controls, whereas person EKYN animals confirmed the estimated deficits.
Conclusions: Collectively, our results provide evidence that KP changes in the fetal talent alter neuronal improvement and cause age-dependent results on neurochemistry and cognitive performance.

I pour boiling water at 100 degrees Celsius into a cup at 50 degrees Celsius. Once the water touches the cup, the cup starts to heat up and the water starts to cool down... Eventually both the water and the cup will reach what temperature?
Answers
Answer:
75 degrees Celsius
Explanation:
Assuming that there is no heat lost to the surrounding, heat energy would move from the water to the cup until an equilibrium temperature is reached. At equilibrium, both the water and the cup would have the same temperature the sum of which would be equal to the sum of their initial temperatures.
Sum of initial temperatures = 100 + 50 = 150 degrees Celsius
At equilibrium, the temperature is divided equally; 150/2 = 75 degrees Celsius
Hence, both the water and the cup will reach 75 degrees Celsius temperature.
