Which learning process occurs when the same response happens in reaction to many similar stimuli? a. acquisition b. discrimination c. extinction d. generalization

Answers

The correct answer is d. Generalisation.

When the same reaction takes place in response to numerous similar stimuli, generalisation, a learning process, occurs.

Learning is a long-lasting modification of behaviour brought on by experience. Although it's a widely used word, it's not a technical term. If someone behaves as a result of experience, they ought to act differently than they did in the past. The propensity to react to stimuli that mirror the original conditioned stimulus is known as generalisation.

For instance, the stimulus would be modified to being stroked rather than scratched if the dog had been trained to expect to be scratched before the meal arrived. He discovered that the dogs' salivation was also triggered by similar stimuli, a phenomenon called generalisation.

How to make bacteria as a treatment for sewage waste

Answers

Answer: Bacteria break down organic material in wastewater and form the floc that settles and separates solids from liquids. Controlling F/M ratio–a vital component to creating a favorable environment for wastewater bacteria–can be accomplished through the use of bioremediation products. Bacteria account for 95% of the microorganisms in wastewater. They are single-celled microorganisms that are classified based on their response to oxygen.

Aerobic bacteria use oxygen, which is added mechanically, to break down wastewater contaminants, converting it into energy. Bacteria use this energy to grow and reproduce. Anaerobic bacteria obtain oxygen from their food source. As anaerobic bacteria break down sludge, they produce methane gas. This methane gas can be used as an alternative energy source, called biogas, to fuel the wastewater treatment process. Anaerobic bacteria can also be used to lower the amount of phosphorus in the effluent. Although they prefer oxygen, facultative bacteria can switch between aerobic and anaerobic forms in response to their environment.

Which of the following methods of radiation dosimetry is most commonly used for patients and personnel?

Malaria, bubonic plague, lyme disease
Thermoluminescence dosimetry (TLD)
NPO 8 hours before the examination

Answers

Thermoluminescence Dosimetry (TLD) is the radiation dosimetry technique that is most frequently utilised for patients and staff. TLD uses detectors that were especially created to assess how much radiation an individual has been exposed to.

The stored energy in these detectors, which are primarily constructed of crystalline minerals, is released as light when they are heated after being subjected to radiation. The radiation dosage absorbed is inversely correlated with the intensity of the light that is emitted. TLD is frequently utilised in medical contexts for patient and staff monitoring since it gives precise and trustworthy assessments of radiation exposure. It is a crucial tool for maintaining optimum radiation doses and guaranteeing radiation safety in healthcare settings.

If DNA code consists of only four components how can so much variety among organismis of the same spices?.






Answers

Explanation:

Although DNA code consists of only four nucleotide components (adenine, thymine, cytosine, and guanine), the sequence of these nucleotides can vary extensively, which allows for the incredible diversity among organisms of the same species.

The sequence of these nucleotides determines the sequence of amino acids in a protein, and proteins are responsible for many of the traits and functions of an organism. Small differences in the DNA sequence can result in differences in the protein sequence, which can lead to variations in traits and functions.

Additionally, genetic diversity within a population can arise through various mechanisms such as mutations, genetic recombination, and gene flow. Mutations are random changes in the DNA sequence that can be beneficial, detrimental, or neutral to an organism. Genetic recombination occurs during meiosis when homologous chromosomes exchange genetic material, resulting in new combinations of genes. Gene flow occurs when individuals from different populations interbreed, bringing new genetic material into the population.

Overall, the combination of small differences in the DNA sequence, as well as genetic diversity within a population, contributes to the incredible variety among organisms of the same species despite the DNA code consisting of only four components.

Explanation:

Find any organism that is connected to the boa constrictor by the arrows that represent the flow of food energy. Whether it be something that gives the boa constrictor energy or relies on the boa constrictor for energy write it down. Any of the organisms that have an arrow pointing from it to the boa constrictor will be used for food energy by the constrictor. If most constrictors are removed that means the organism used as energy (Sloth and Coati) will increase because there are not as many constrictors to consume it. The food source for the Sloth and Coati (Strangler Fig) would decrease because there are more Sloths and Coatis to consume it.

?which animal has the highest weight-specific total rate of evaporative water loss chicken hummingbird ostrich screech owl

Answers

b) Hummingbirds have the highest weight-specific total rate of evaporative water loss.

In the field of biology, hummingbirds can be described as small birds that have the ability to fly just like the majority of other birds. In order to fly, hummingbirds need to have a weight-specific rate for the loss of water.

This weight-specific loss of water by evaporation is higher in hummingbirds because in order to fly, the weight-to-surface ratio of the hummingbirds needs to be small. Hence, a higher amount of water is lost by evaporation in hummingbirds to maintain the specific weight required for flying.

Other options, like chicken, are not correct as chickens do not need to be weight-specific as they do not fly, and hence much of their water is stored rather than being evaporated.

The question will correctly be written as:

Answers

One way N. gonorrhoeae became resistant to penicillin was by acquiring a plasmid that carries the penr penicillin resistance gene, which encodes a β-lactamase enzyme that cleaves penicillin to an inactive form.

β-lactamases are enzymes that belong to the class of serine proteases and possess the ability to hydrolyze the β-lactam ring of penicillins and other β-lactam antibiotics. This enzymatic cleavage renders penicillin ineffective in inhibiting the synthesis of the bacterial cell wall, the primary mechanism of its bactericidal action.

The acquisition of the penicillin resistance plasmid carrying the penr gene has provided N. gonorrhoeae with a mechanism to counter the effects of penicillin treatment, leading to the development of antibiotic resistance. This emphasizes the ongoing evolutionary arms race between bacteria and the antibiotics used to combat them.
