How does pH make a difference to beans growing?5 answerspH plays a crucial role in the growth and development of beans. Different pH levels in the soil can significantly impact bean plants. Beans are highly sensitive to soil pH variations, with acidic conditions generally being detrimental to their growth. For instance, acidic soils inhibit clover growth, reduce carotenoid content in beans, and hinder nitrogen fixation. Conversely, neutral to slightly alkaline pH levels promote healthier bean plants with better growth, leaf development, and nutrient absorption. Additionally, adjusting soil pH through liming can be crucial for optimizing bean production in acidic soils. Overall, maintaining the appropriate pH range in the soil is essential for ensuring optimal bean growth, nutrient uptake, and overall plant health.
What FBS provides the cells after thawing of cells?5 answersAfter thawing, FBS (Fetal Bovine Serum) provides essential components for the cells, including hormones, growth factors, attachment and spreading factors, and transport proteins. Different concentrations of FBS have varying effects on cell viability and functionality post-thawing. Research indicates that cryopreservation media containing 95% FBS with 5% DMSO helps maintain colony formation and chondrogenic abilities of synovial mesenchymal stem cells (MSCs). Similarly, spermatogonial cells frozen in media with 60%-70% FBS show the highest viability after thawing. Furthermore, a cryopreservation medium with reduced DMSO concentration and no FBS (5% DMSO) is found to maintain high viability and functional properties of human adipose-derived MSCs, indicating that FBS is not always necessary for successful cryopreservation of cells.
Why it is important to maintain pH in jam?4 answersMaintaining pH in jam is crucial for several reasons. Firstly, it affects the stability and properties of the jam, influencing factors such as texture, flavor, and shelf life. Secondly, pH plays a role in controlling microbial growth, which is essential for food safety and preventing spoilage. Lastly, in the context of using jam in combination with other food products, such as blending with cream for whipping, maintaining the pH is important for preserving the properties of the combined products.
What is the ph of human skin around penis?5 answersThe pH of human skin around the penis varies depending on the condition and treatment. In normal men, the cutaneous glans temperature is within the range of 4.1-5.8, indicating an acidic pH. However, men with semirigid penile prostheses (SRPPs) have significantly lower cutaneous glans temperatures, suggesting a colder glans compared to men with normal erectile function, erectile dysfunction (ED), inflatable penile prostheses (IPPs), and those who have received an injection of trimix. The mean temperature difference between men with SRPPs and those in other groups is 1.44±0.40°C. It is important to note that the pH of the skin can vary throughout the day, with a significant fall in axillary skin surface pH between the morning and the evening. However, specific pH values for the skin around the penis are not mentioned in the abstracts provided.
How important is pH in water aquaculture?4 answerspH is highly important in water aquaculture as it affects fish growth rate and health. Maintaining optimal pH conditions is crucial for freshwater habitats. Water quality is a key factor in the success of aquaculture operations, and pH plays a significant role in determining the productivity of the production system. The pH value of water is an intensity factor that can influence the biological processes of fish, including growth, survival, reproductive performance, and embryology. Monitoring and controlling pH levels in aquaculture water is essential for maintaining optimum conditions for aquatic animals. The invention of pH value detection devices and methods for aquaculture water has helped overcome challenges such as pH meter scaling and fungus growth. Understanding the importance of pH in water aquaculture is crucial for ensuring the success and well-being of aquatic animals.
How does pH affect amphibians?1 answerspH has important ecological effects on amphibians. Acidic and alkaline pH environments can lead to morphological changes in the oral apparatus of tadpoles, affecting their growth and development. Pesticides, when combined with low pH conditions and predatory stress, can become more lethal to amphibians. Lower pH levels have been found to increase the toxicity of herbicides on amphibian embryos and larvae. The suitability of vernal ponds for amphibian reproduction is influenced by the interactions between pH, metals, and water hardness. Variation in acid sensitivity in amphibians is influenced by both genetic and maternal factors. Overall, pH can have significant impacts on the survival, growth, and development of amphibians, and these effects can be influenced by other factors such as pesticides, metals, and genetic variation.
