For cells that are larger, nutrient intake and waste elimination takes a longer time due to the larger distance that must be covered by the same transport processes as the ones taking place in smaller cells. Shapes that maximize surface area help increase the rate of nutrient uptake and waste elimination.
Answer:
in the nucleus of the cell
The answer is B, each gamete contains the same number of chromosomes as the mother. This is through cell division when the parent cells go through two rounds of meiosis 1 and meiosis 2, and all haploid gametes have 23 chromosomes.
If a farmer decides to stop using chemicals like fertilizers and pesticides on his crops, fungi will grow on the plants’ roots to help the plants get more nutrients.
Pesticide is a generic term that refers to all the chemical substances that are used to prevent attack on plants by other living organisms. Fertilizers are chemicals that are added to the soil to aid plant growth.
However, these pesticides have a harmful effect on fungi which helps to increase the uptake of water and nutrients by plants and also to increase availability of nutrients to the plant roots.
However, if the farmer stops using these pesticides, fungi will grow on the plants’ roots to help the plants get more nutrients.

Answer:
Frogs and toads produce a rich variety of sounds, calls, and songs during their courtship and mating rituals. The callers, usually males, make stereotyped sounds in order to advertise their location, their mating readiness and their willingness to defend their territory; listeners respond to the calls by return calling, by approach, and by going silent. These responses have been shown to be important for species recognition, mate assessment, and localization. Beginning with the pioneering experiments of Robert Capranica in the 1930s[1] using playback techniques with normal and synthetic calls, behavioral biologists and neurobiologists have teamed up to use frogs and toads as a model system for understanding the auditory function and evolution. It is now considered an important example of the neural basis of animal behavior, because of the simplicity of the sounds, the relative ease with which neurophysiological recordings can be made from the auditory nerve, and the reliability of localization behavior. Acoustic communication is essential for the frog's survival in both territorial defense and in localization and attraction of mates. Sounds from frogs travel through the air, through water, and through the substrate. The neural basis of communication and audition gives insights into the science of sound applied to human communication.
