Answer 1

Foetus get antibodies through placenta and injection of Antibodies are the example of Passive Immunity .

What is Passive Immunity ?

The transmission of a ready-made antibody's active humoral immunity is known as passive immunity. Natural transmission of maternal antibodies to the fetus via the placenta can result in passive immunity.

The main benefit of passive immunity is that it provides protection right away, as opposed to active immunity, which takes time (a few weeks) to develop. Passive immunity, however, only lasts a few weeks or months. Long-lasting immunity can only be active.When a person acquires antibodies against a disease that were not produced by their own immune system naturally rather than through medical intervention, they are said to have acquired natural passive immunity. This is also known as maternal passive immunity and typically refers to the transfer of antibodies from the mother to the fetus over the placenta.Passive immunity comes in two flavors: synthetic and natural.

max runs a marathon in 2 hours and 40 minutes. most of the atp for this run is supplied by: group of answer choices breakdown of fatty acids anaerobic glucose breakdown aerobic glucose breakdown breakdown of amino acids

Answers

Runners run a marathon in 2 hours and 40 minutes. Most of the ATP for this process is supplied by aerobic glucose breakdown.

Aerobic respiration reactions occur when glucose meets oxygen, then produces carbon monoxide, water, and energy. Aerobic respiration produces 36 ATP of energy, while anaerobic respiration only produces 2 ATP of energy.

The best energy supply for runners is through aerobic respiration because it requires a lot of energy to move.

The aerobic system is the primary energy system used for sprints lasting longer than three minutes. Because long-distance running is primarily limited by the delivery and use of oxygen. So, when warming up you should focus on increasing the ability of the aerobic system to supply oxygen to the muscles while running.

Which statement correctly describes the difference between alcohol fermentation and lactic acid fermentation?
Alcohol fermentation produces lactate, and lactic acid fermentation produces ethanol.
Alcohol fermentation is an aerobic pathway, and lactic acid fermentation is an anaerobic pathway.
Lactic acid fermentation produces lactate, and alcohol fermentation produces ethanol.

Answers

The difference between alcohol fermentation and lactic acid fermentation is lactic acid fermentation produces lactate, and alcohol fermentation produces ethanol.

Lactic acid fermentation vs alcohol fermentation

Fermentation is the metabolic process in which sugars are broken down anaerobically. This condition means in absence of oxygen.

The fermentation pathway is still related with cellular respiration process but there is an extra reaction after Glycolysis. It happens as you are making bread, beer, and doing exercise too hard. 

There are 2 types of fermentation, lactic acid fermentation and alcohol fermentation.

Lactic acid fermentation. In lactic acid fermentation, NADH transfer the electrons directly into pyruvate and produce the lactate as a byproduct. For instance, the process of making yoghurt undergo this kind of fermentation. Also, the muscle cells when you’re exercising too hard. Alcohol fermentation. In alcohol fermentation, NADH donate the electrons into pyruvate derivatives (acetaldehyde) and generating ethanol (alcohol). It needs two process from pyruvate to ethanol.

FILL IN THE BLANK. The property of an antimicrobial agent to be highly toxic against its target microbe while being far less toxic to the cells of the host organism is called _______________ toxicity.

Answers

The property of an antimicrobial agent to be highly toxic against its target microbe while being far less toxic to the cells of the host organism is called selective toxicity.

What is toxicity?

A substance's toxicity refers to the dosage required for it to harm a living thing. When a material starts to harm an organism, it becomes toxic. In spite of common assumption, every drug has a definite level of toxicity. Even water and oxygen, in certain amounts, are harmful to living things. Furthermore, poisons affect certain species in various ways. A substance's toxicity, like that of sulfur, will differ depending on the species. Large amounts of sulfur are lethal to humans. Sulfur is an essential and pleasant ingredient for the creatures that live in the heat of volcanic vents at the bottom of the ocean, though.It was no longer accurate to forecast human toxicity levels using laboratory animals once it was realized that various poisons might affect comparable species in wildly diverse ways. To research and assess toxicity in accurate and ethical manners, new procedures and tests are being created. Toxicology is the field that studies the toxicity of various compounds.

Selective toxicity:

According to the theory of selective toxicity, a chemical may be poisonous to a pathogen but not to the infected host organism.Antimicrobial drugs like penicillin, metronidazole, and chloramphenicol work by interacting with biological components specific to their target organism. This makes it possible for the chemical to only harm cells that have the target element, such as an enzyme involved in the creation of cell walls or a specific metabolic ribozyme.

Hence, this is selective toxicity.

Fetuses with this condition are characterized by enlarged kidneys. Since the kidney is enlarged it prevents the growth of lungs and makes the breathing of the fetus hard. Children with this condition are usually smaller in size than normal children because of decreased kidney and lung function. Also amniotic fluid of the mother's womb is also low.

what is the role of the electron transport chain in forming the h gradient across the inner mitochondrial membrane?

Answers

The energy released as electrons are passed down the electron transport chain is used to pump H+ from the mitochondrial matrix to the intermembrane space creating an H+ concentration gradient.

The transfer of electrons from electron donors to electron acceptors via redox reactions is accomplished by a group of protein complexes and other molecules that connect protons (H+ ions) through a membrane.

It is an exergonic method of transporting electrons. Due to an electrochemical proton gradient produced by the redox reaction energy, adenosine triphosphate produced (ATP). Through the exergonic flow of electrons from NADH to FADH2, the chain serves as an energy converter that pumps H+ from the mitochondrial matrix to the intermembrane gap. The gradient of the H+ is likely to disperse on its own when it returns across the membrane. And the ATP synthases are the only areas of the membrane that let H+ enter through.

neurons are cells of the nervous system. as part of its normal function, a neuron pumps sodium ions (na ) out of the cell and potassium ions (k ) into the cell. which statement describes the role of energy in this process?

Answers

Neurons are cells of the nervous system. As part of its normal function, a neuron pumps sodium ions (Na + ) out of the cell and potassium ions (K +) into the cell. The process requires energy that is provided by ATP.

The nervous system's cells are called neurons. The neurons use electricity to transmit information throughout the nervous system. And the differential in charges between inside and outside the cell is what creates that electricity. A difference in the cell's positive charge is where this difference in charges BEGINS. Currently, Na+ and K+ concentrations outside the cell of neurons vary due to their watery surroundings. K+ concentration is higher inside the cell than outside, but Na+ concentration is higher outside the cell than inside. However, because there are more Na+ than K+, Na+ has a tendency to enter cells while K+ has a tendency to exit them, maintaining the equilibrium of Na+ and K+ inside and outside of the cell.

The sodium-potassium pump creates by retaining K+ and discarding Na+. Because the cell is operating in opposition to the equilibrium state (equal amounts of Na+ and K+ coming in and going out), more Na+ must be expelled than must be brought in during this process (because there are more Na+ than K+). It is ion active transport.

The first step in the electric potential to transmit information through the nervous system is made possible by this difference in positive charges.
