mmature B lymphocytes undergo clonal deletion in the bone marrow. Group of answer choices True False
True, Immature B lymphocytes undergo clonal deletion in the bone marrow.
What are immature B lymphocytes? How does it undergo clonal deletion in the bone marrow?
In the bone marrow and thymus, lymphocytes are born. The names of T cells and B cells come from the organs in which they are born. T cells form in the thymus, whereas B cells form in the bone marrow of adults or the liver of fetuses in mammals.
Most mammals' bone marrow is where immature B lymphocytes are made. The B cell will die via apoptosis, also known as a clonal deletion if it fails at any stage of the maturation process. Positive selection is used in this situation. Negative selection is also used to check the autoreactivity of B cells. These B cells will perish through clonal deletion if they have a high affinity for attaching to self-antigens. In the bone marrow, immature B cells that bind self-antigen perish because they are highly susceptible to antigen binding.

Phenytoin blocks the opening of voltage-gated na channels in neurons. therefore, this action has its primary effects on which part of the neuron?
Numerous antiepileptic medications, such phenytoin, have been designed to block voltage-gated sodium channels (VGSC) in neuronal membrane. In addition, multiple toxins and pharmacological modulators work by attaching to various biophysical states of the VGSC to cause their effects. Depending on how modulatory agents act, some VGSC states are stabilized or destabilized, altering the channel's biophysical properties. The first anticonvulsant to successfully treat epileptic disorders without causing undesirable side effects such as brain drowsiness was phenytoin.
Phenytoin has been indicated to block high-frequency neuronal activity potentials from the inner vestibule of the pore, as demonstrated by electrophysiological research and site-directed mutation.
Frequency and voltage both affect phenytoin binding.
There are theories that phenytoin interferes with the late sodium current that sustains depolarizations in epilepsy by blocking non-inactivated channels.

Stubble bristles (Sb) is dominant to wildtype bristles (Sb+) in Drosophila melanogaster. In a population where there are 137 flies with wildtype bristles and 836 flies with stubble bristles, what are the allele frequencies for the Sb and Sb+ alleles (assuming the population is in Hardy-Weinberg equilibrium)? Please calculated your answers to 3 decimal places.
f(Sb)=
f(Sb+)=
If the population is in Hardy-Weinberg equilibrium, what proportion of the population would you expect to be heterozygous?
Populations in H-W equilibrium have the same allelic and genotypic frequencies generation after generation. f(Sb) = p = 0.626. f(Sb+) = q = 0.374. F(SbSb+) = 2pq = 0.468
What is Hardy-Weinberg Equilibrium?
The Hardy-Weinberg equilibrium is a theory that states that, assuming a diallelic gene,
⇒ The allelic frequencies in a locus are represented as p and q.
• The frequency of the dominant allele p(X) is p
• The frequency of the recessive allele p(x) is q
⇒ The genotypic frequencies after one generation are
• p² (Homozygous dominant genotypic frequency),
• 2pq (Heterozygous genotypic frequency),
• q² (Homozygous recessive genotypic frequency).
Allelic and genotypic frequencies remain the same through generations in a population that is in H-W equilibrium.
The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
In the exposed example,
Sb is dominantSb+ is recessive ⇒ wild typePopulation size ⇒ 137 + 836 = 973Individuals with wildtype bristles ⇒ 137 ⇒ Sb+Sb+Individuals with stubble bristles ⇒ 836 ⇒ SbSb and SbSb+First, we will get the frequencies.
To do it, we will use the number of individuals. These values will tell us about phenotypic frequencies,
Phenotypic frequency
F(wildtype) = q² = 137/973 = 0.14F(stubble) = p² + 2pq = 836/973 = 0.86Now, we will use the frequency of the recessive phenotype to get its genotypic and allelic frequencies.
F(Sb+Sb+) = q² = 137/973 = 0.14 ⇒ Recessive Genotypic frequency
f(Sb+) = q = √0.14 = 0.374 ⇒ Recessive Allelic frequency
Now, Since this population is in H-W equilibrium, we will use q (recessive allelic frequency) to get the dominant allelic frequency and the dominant genotypic frequency. To do it, we will clear the following equation,
p + q = 1
p + 0.374 = 1
p = 1 - 0.374
p = 0.626 ⇒ Dominant Allelic frequency
F( SbSb) = p² = 0.626² = 0.392 ⇒ Dominant Genotypic frequency
Finally, we will get the heterozygous frequency. There are two options,
To susbtract the dominant genotypic frequency to the dominant phenotpic frequency,F(SbSb + SbSb+) - F(SbSb) = 0.86 - 0.392 = 0.468
To clear the following equation,p² + 2pq + q² = 1
0.392 + 2pq + 0.14 = 1
2pq = 1 - 0.392 - 0.14
2pq = 0.468
Answers:
- f(Sb) = p = 0.626 ⇒ Dominant Allelic frequency
- f(Sb+) = q = 0.374 ⇒ Recessive Allelic frequency
- F(SbSb+) = 2pq = 0.468 ⇒ Heterozygous frequency

The majority of neurotransmitters migrate across the synaptic gap and latch onto receptor sites of the receiving neuron's:
Dendrites of the postsynaptic neurons are the structures that receive chemical messages -neurotransmitters- from the presynaptic neurons. The correct option is D. Dendrites.
What is a synapse?
Neurons are cells that communicate with each other through the transmition of nervous impulses.
Every neuron forms connections with other neurons or with effector organs, such as the muscle. These connections are known as synapses.
Synapses can be either chemical or electrical. The most common one is the chemical synapses that involve the release of a substance known as a neurotransmitter.
During chemical synapses, when a presynaptic neuron sends information, it releases neurotransmitters. This event is done through exocytosis.
The neurotransmitter is a molecule that travels through the synaptic space forward to the dendrites of the other neuron or to the effector cell. Once the chemical reaches the postsynaptic membrane, it binds to its receptors.
This binding neurotransmitter-receptor produces excitatory postsynaptic potential, which is the depolarization of the postsynaptic cell.
Once the action potential is initiated, it spreads to the rest of the membrane, depolarizing it.
According to this framework, when two neurons communicate, the neurotransmitter released by one of them reaches the receptors located in the dendrites of the postsynaptic cell.
Dendrites are the structures that receive chemical messages from the other cells.
The correct option is D. Dendrites.

The relationship between the caterpillars and milkweed is characterized by - for the milkweed and + for the caterpillar
The monarch butterfly can only survive if it feeds on milkweed during its whole life cycle. Because monarch butterfly larvae, also known as caterpillars, can only feed on milkweed, this species of butterfly is also known as the "milkweed butterfly."The female monarch butterfly lay her eggs on the bottom of the milkweed leaves, which will offer the developing larvae protection as they grow. The big leaves function similarly to umbrellas, protecting the eggs from the excessive heat of the summer sun and providing cover from the heavy downpours. In addition, the leaves provide a wonderful place to conceal oneself from any predators that might be interested in eating the eggs before the larva hatches. As soon as the eggs hatch, the larvae will begin to feed on the leaves of the milkweed plants. For the first few days of their lives, they will consume food continuously, day and night. The milkweed provides the young caterpillars with more than just food while they develop. Milkweed offers a one-of-a-kind defence against predators to both the monarch butterfly larvae and the adult butterflies. The larvae consume a significant proportion of the milkweed plant's dangerous compounds since the milkweed plant itself contains poisonous elements. As a result, the monarch butterfly themselves become poisonous.
