Selective media are important in the initial stages of isolating a specific type of microorganism from samples containing many other species, such as saliva or feces.

A selective media is one that enables one or more species of microorganisms to be chosen.

All other microbes will be prevented from growing on or in the medium, leaving just these to do so.

A certain "selected" microbe is chosen for growth using selective medium. For instance, if a certain microbe is resistant to a specific antibiotic, the antibiotic can be given to the medium to stop the growth of other, non-resistant organisms.

A specific bacterial species or genus is isolated using a selective culture medium. The aim of this type of medium is to remove undesirable microbial flora after adding a number of inhibitors to the culture medium.

Thus, the answer is media, visit:

The difference in distribution of ions across the neuron membrane is called the ion concentration gradient.

The ion concentration gradient refers to the difference in the concentration of ions, such as sodium (Na⁺), potassium (K⁺), and chloride (Cl⁻), on either side of the neuron membrane. This difference in concentration creates an electrochemical gradient, which is vital for the generation and propagation of action potentials. The neuron membrane is selectively permeable, allowing certain ions to pass through ion channels.

The distribution of ions across the neuron membrane is maintained by ion pumps, such as the sodium-potassium pump, which actively transport ions against their concentration gradients. This establishes a higher concentration of sodium ions outside the neuron and a higher concentration of potassium ions inside the neuron. The ion concentration gradient is crucial for the movement of ions during an action potential, as it determines the direction and speed of ion flow across the neuron membrane.

D. Fossil record.

Explanation:

The fossil record evidences the evolutionary history of life on Earth by tracing the life forms that existed from earlier geological times and remained in the sedimentary rock. Different fossils were dated in the sedimentary rocks of all geological periods. The simplest forms of life were discovered in the oldest rocks, while more complex fossil organisms were found in the newest rocks. In consequence, the fossil record can support the evolutionary process as proposed by Charles Darwin, who indicated that the simplest forms of life evolved in more complex organisms.

The part of the hop plant that is of most interest to brewers is the hop cone, specifically the female flower cluster known as the strobile.

Hop cones contain glandular trichomes, which produce and store compounds called alpha and beta acids, as well as essential oils. These compounds provide the characteristic bitterness, flavor, and aroma that hops impart to beer. Brewers typically use dried hop cones or hop pellets, which are made by grinding and compressing the cones, to add bitterness, flavor, and aroma to the beer during the brewing process. Different hop varieties have unique combinations of these compounds, and brewers may choose to use different varieties or combinations of varieties to achieve the desired flavor profile in their beer.

Hi! Pain receptors, also known as nociceptors, play a crucial role in our body's ability to detect potentially harmful stimuli such as heat, cold, or pressure. In conclusion, having pain receptors sensitive to various vigorous stimuli, such as heat, is advantageous because it provides protection, helps us adapt, and maintains overall well-being.

Having pain receptors sensitive to various vigorous stimuli is advantageous for a few reasons:1. Protection: Sensitivity to different types of stimuli allows the body to quickly respond to potential threats. For example, when we touch a hot surface, the pain receptors detect the heat and send a signal to the brain, prompting us to withdraw our hand to avoid further injury.2. Healing: Pain signals help the body identify areas that need attention and promote the healing process. For instance, pain from an injury encourages us to protect the affected area, allowing it to heal.3. Adaptation: Our sensitivity to pain allows us to learn from potentially harmful experiences and adapt our behavior to avoid them in the future. For example, after experiencing the pain from touching a hot object, we become more cautious around heat sources.4. Overall well-being: Pain receptors also play a role in maintaining the body's overall well-being. Detecting changes in temperature, pressure, or other environmental factors enables the body to adapt and maintain homeostasis, ensuring optimal functioning.
