The administration of antibodies isolated from one individual or species to another to protect the recipient from a toxin or disease is referred to as passive immunity.
Immunity to a disease is achieved due to the presence of antibodies to the disease in the human system. Antibodies are proteins produced by the body to neutralize or destroy organisms that carry toxins and diseases. Antibodies are disease-specific.
passive is the type of immunity that occurs when a person is given an antibody rather than making it by their immune system. For example, passive immunity occurs when the baby receives the mother's antibodies through the placenta or breast milk.
There are two types of immunity: active immunity and passive immunity. Active immunity occurs when our own immune system is responsible for protecting us from pathogens. Passive immunity occurs when we are protected from pathogens by the immunity of others.

If a post-synaptic ionotropic receptor is permeable to potassium and assuming all normal ionic distributions, the response in the post synaptic cell will be inhibitory.
Ion channels that open in response to the binding of a neurotransmitter are known as ionotropic receptors, also known as neurotransmitter-gated or ligand-gated channels. If there is a synapse, they can be found anywhere along the neuron, though they are typically found around the dendrites or cell body.Ligand-gated channels play a crucial role in the transmission of information from one neuron to another.Postsynaptic receptors can identify two different kinds of neurotransmitters.

cannot. Birds with the mutation no longer fly north during winter and stay to feed on mangoes. What is likely to happen over time?
OA they will evolve into a new species that can't breed with the other wombo birds
OB. the other wombo birds will evolve and become mango eaters too
OC. a new species of mangoes will evolve and live along the wombo birds migration route
OD. they will eat all the mangoes and start migrating again
A mutation occurred in a population of wombo birds, and birds with the mutation are able to eat mangoes, but those without the mutation cannot. This is due to the fact that the other wombo birds will evolve and become mango eaters too, which is option B. So option B is the correct answer.
Since birds with the mutation can eat mangoes, and mangoes appear to be a valuable food resource, natural selection will likely favor the birds with the mutation. As a result, over generations, more and more birds in the population will carry the mutation, and eventually, the entire population may evolve to become mango eaters. This process may take time, and the rate of evolution will depend on factors such as the size of the population, the rate of mutation, and the availability of mangoes as a food source.

The statement that the integument is strictly composed of the skin and It does not include the various accessory structures that may be present on or beneath the skin layers is False.
Composition of integumentTogether with the underlying epidermal cells that secrete the cuticle, the cuticle and integument make up the skin. The cuticle functions as the insect's exoskeleton, the location of muscle attachment, and the first line of protection against fungi, bacteria, predators, parasites, and environmental toxins, including pesticides. The integument plays a role in behavior, osmoregulation, water control, eating, excretion, desiccation resistance, and as a food reserve.

In an energy pyramid, the amount of energy at the producer level is 475,650 kilocalories. the pyramid has four trophic levels, including the producer level. assuming that 10% of the energy is retained at every level, how much energy is available for the second-level consumers? the energy available for the second-level consumers is kilocalories.
The energy available for the second-level consumers is 4756.5 kilocalories.
A trophic level is a position in the food chain or nutrient cycle of an ecosystem. Based on their eating habits, organisms in a food chain are divided into various levels. The first trophic level is usually occupied by producers that can synthesize their own food.
The efficient energy transfer from one trophic to another is only 10% rest of the energy is lost in the ecosystem. The studies of the transfer of energy in different food chains in a large number of ecosystems have revealed a uniform pattern, which is stated as the 10 percent law by Lindemann. According to this law, only 10 percent of the energy entering a particular trophic level of organisms is available for transfer to the next higher trophic level.
Calculation:
Producers (475650 kilocalories) —> Primary consumers (10% of 475650 = 47565 kilocalories) —> Secondary consumers (10% of 47565 = 4756.5 kilocalories).
So, the energy available for second-level consumers is 4756.5 kilocalories.

What is homologous evolution?Homologous evolution is similarity of the structure, physiology, or development of different species of organisms based upon their descent from a common evolutionary ancestor.
Homologous structures include the human arm, a bird or bat's wing, a dog's leg, a dolphin or whale's flipper, and the wing of a bird or a bat.

Why is salivary amylase active for only an hour or so, whereas lingual lipase isn't active until reaching the stomach
Salivary amylase will be active for only an hour or so because the optimum pH for activity of amylase is about 6.7–7.0 which is available in the mouth but the pH of the stomach is acidic around 1-2 due to which the amylase enzyme becomes inactive in short-time.
The lingual lipase enzyme is present in the saliva but isn't active until reaching the stomach because this enzyme is acid stable and works efficiently in the stomach, not in the mouth.
Amylase enzyme is secreted in the mouth and is responsible for the breakdown of starch in food into sugars and it starts acting as soon as we put food in the mouth whereas Lingual lipase enzyme is secreted along with saliva but it is not active in the mouth rather its activity starts in the stomach which is responsible for the degradation of triacylglycerol molecules.

The P50 for myoglobin is 2.8 torr. At what oxygen concentration will myoglobin be 75% saturated with oxygen
At 8.4 torr myoglobin will be 75% saturated with oxygen.
Calculation :
P50 is the partial pressure of the system. To achieve 50% saturation of oxygen to bind to myoglobin, the partial pressure needed is P50
P50 =2.8 torr
so, Mb+ O2 = MbO2
K= [Mb] [O2]/[MbO2]......................(1)
Yo2 ( fractional saturation of myoglobin )
Yo2=[MbO2]/[Mb]+[MbO2]..........................(2)
From equations (1) and (2)
We get Yo2= [O2]/K+[O2]= Po2 /K+ Po2
i)Yo2= 50% =2.8/K+2.8
0.5= 2.8/k +2.8
So, K= 2.8
ii) 75 % = [O2]/K+[O2]= [O2]/2.8+ [O2] = 8.4
Therefore, the oxygen concentration will be 8.4 torr.
