how many homologous pairs of chromosomes are present in a haploid cell that has 8 chromosomes and is in anaphase II of meiosis ll? explain your answer
Answers
Answer:
In many ways, meiosis is a lot like mitosis. The cell goes through similar stages and uses similar strategies to organize and separate chromosomes. In meiosis, however, the cell has a more complex task. It still needs to separate sister chromatids (the two halves of a duplicated chromosome), as in mitosis. But it must also separate homologous chromosomes, the similar but nonidentical chromosome pairs an organism receives from its two parents.
These goals are accomplished in meiosis using a two-step division process. Homologue pairs separate during a first round of cell division, called meiosis I. Sister chromatids separate during a second round, called meiosis II.
Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
difference between incomplete and complete ventilation? any 4
Answers
Answer:
Due to exchange of gases i.e. normal and abnormal.
Explanation:
The main difference between incomplete and complete ventilation is the occurrence of normal and abnormal exchange of gases. The mechanism in which the exchange of gas happens completely without any difficulty is called complete ventilation. It is the process in which the required amount of oxygen is inhaled or inspired and appropriate amount of carbon dioxide is exhaled out of the body while on the other hand, incomplete ventilation is a mechanism in which exchange of gases is not normal.

Excess postexercise oxygen consumption (EPOC) is also known as oxygen debt.
a. True
b. False
Answers
Answer:
True.
Explanation:
Excessive postexercise oxygen consumption can also be called oxygen deficit. It occurs after an individual completes a physical activity. Physical effort does not allow oxygen consumption to be normalized as soon as the body comes to rest and for this reason, the body begins to breathe and demand oxygen more intensely. This moment is known as excessive postexercise oxygen consumption, or oxygen debit. The intensity of breathing at this time will depend on the physical effort made, the weight loss and the increase in total caloric expenditure.

A phosphate group has the following chemical composition:
a. -OH
b. -COOH
c. -PS2
d. -CH3
e. -PO4
Answers
Answer: The phosphate group has the chemical composition [tex]-PO_{4}[/tex].
Explanation:
A phosphate group is a group where one phosphorus atom is attached to four oxygen atoms.
The oxygen atoms are attached to the phosphorus atom via single bond and one oxygen atom is attached to the phosphorus atom via double bond.
The chemical formula which represents a phosphate group is [tex]-PO_{4}[/tex].
Thus, we can conclude that phosphate group has the chemical composition [tex]-PO_{4}[/tex].
what are some of the actions that the somatic nervous system does?
Answers
Answer
It regulates voluntary activities.
It relays information to and from skin and skeletal muscles
Explanation
The somatic nervous system is part of the peripheral nervous system (part of the nervous system consisting of nerves and ganglia, and whose essential role is the transmission of information between the central nervous system - brain and spinal cord - and organs). It intervenes in the voluntary control of movements (or involuntary movements in case of reflexes, but this is different from the involuntary activities) (efferent fibers) and in the perception of external stimuli (afferent fibers).
The somatic nervous system controls the movements of skeletal muscle (which are generally voluntary) and the environmental perception, (think to the arc reflex).
The involuntary activities (proposition 1) mean automatisms like the heartbeat, respiration, secretions of hormones or sweat

How does the high specific heat of water help maintain the temperature of earth?
A By heating and cooling more slowly than land or air
B. By heating and cooling faster than land or air
с.
By heating faster but cooling more slowly than land or air
Answers
The high specific heat of water help maintain the temperature of the Earth by heating and cooling more slowly than land or air. Thus, the correct option is A.
What is the specific heat of water?The specific heat of an object is the amount of heat which is required to increase or raise the temperature of unit mass of that particular substance through one degree celsius. Specific heat is represented by the symbol 'c'. Its unit in SI system is Joule /(kg °C) and in CGS is cal / (gm °C).
The high specific heat of water helps in regulating the rate at which air changes its temperature, which is why the temperature of the planet change between different seasons is gradual rather than sudden, especially the geographical locations near the ocean.
Therefore, the correct option is A.

The bacterium Methylophilus methylotrophus can use methanol and ammonia for protein synthesis. The glutamate dehydrogenase gene from E. coli was introduced into M. methylotrophus using recombinant DNA techniques. Under high ammonia conditions, the introduction of the glutamate dehydrogenase gene into M. methylotrophus resulted in an increase in protein yield. Select the statements that are reasonable explanations for the increased protein yield in the modified M. methylotrophus. Glutamate dehydrogenase catalyzes the formation of glutamate and glutamine in a two-step process. Both glutamate and glutamine play a key role in amino acid synthesis, thus an increase in levels of glutamate and glutamine increase protein synthesis. Glutamate dehydrogenase has a low affinity for NH^+_4, and can only catalyze the formation of glutamate from alpha-ketoglutarate and NH^+_4, when the concentration of NH^+_4 is high. Glutamate dehydrogenase has a high affinity for NH^+_4, thus the rate of glutamate synthesis increases exponentially under high ammonia conditions. Glutamate is the amino group donor for most transamination reactions involving amino acids, thus an increase in glutamate concentration increases protein synthesis.
Answers
Answer:
- Glutamate dehydrogenase has a low affinity for NH+4, and can only catalyze the formation of glutamate from alpha-ketoglutarate and NH+4, when the concentration of NH+4 is high.
- Glutamate is the amino group donor for most transamination reactions involving amino acids, thus an increase in glutamate concentration increases protein synthesis.
Explanation:
Glutamate dehydrogenase (GLDH) is an enzyme found in prokaryotic and eukaryotic cells, which is known to catalyze the reversible oxidative deamination of glutamate (Glu) to alpha-ketoglutarate and ammonia at the same time the oxidation of NADH to NAD. In bacteria, this enzyme (GLDH) is efficient only at high concentrations of the ammonium cation (NH4+), because it has a low affinity for NH4+. Moreover, transamination is a pathway that involves the transfer of an amino group from one amino acid to a ketoacid in order to form new amino acids (this reaction is responsible for the deamination of most amino acids). Glu is the donor of amino groups in most of the reactions catalyzed by enzymes involved in the transamination between an amino acid and an alpha-keto acid. In consequence, in presence of GLDH, a high concentration of Glu will increase the production of new amino acids and therefore also protein synthesis.

When curare, a neuromuscular poison, is dropped onto an isolated muscle-nerve preparation in a laboratory, the muscle does not contract when the nerve is stimulated, even though neurotransmitter is released from the nerve cell. Why does this happen
Answers
Answer:
Explanation:
Whenever the nerve terminal's action potential depolarizes, calcium enters the cell through the channels. Calcium allows acetylcholine (ACh) to be released more easily. These ACh molecules subsequently circulate into the synaptic cleft and attach to the motor end-plate of the nicotinic cholinergic receptors. Acetylcholine molecules connect to nicotine ion-channel receptors present on cell membrane the of muscle cells, enabling the ion channels to open. Calcium ions then enter the muscle cell, kicking off a series of events that eventually result in muscular contraction.
Curare is a kind of neuromuscular relaxant blocker that is non-depolarized in nature. Nondepolarizing muscle relaxants work as competitive agonists, binding to ACh receptors but failing to activate ion channels. As a result, they inhibit ACh from bonding, preventing the development of endplate potentials and inducing muscle paralysis.
