Answer:
Fertile soils teem with life. Porous loamy soils are the richest of all, laced with organic matter which retains water and provides the nutrients needed by crops. Sand and clay soils tend to have less organic matter and have drainage problems: sand is very porous and clay is impermeable.
Answer:
Muscle contraction is an example of mechanical contraction.
Explanation:
Muscular contraction is the activation of generating tension which appear in the muscle fiber as it does't change the length of muscle and is followed by muscular relaxation.
Muscle contraction is based on force and length.
The process of skeletal muscle contraction is an energy requiring process.
In order to perform mechanical work,actin and myosin utilizes the chemical energy into ATP that ultimately require during muscle contraction and relaxation.
In a working muscle,glucose is released from glycogen that are stored in the muscle by the process of glycolysis in which glucose broken down into ATP that is required by cells and tissues.
Answer:
The correct answer is "both Cdc6 and Cdt1"
Explanation:
The replisome is a complex molecular system that allows for the replication of DNA in yeast. There are multiple genes that participate in the replisome function, however if a researcher finds out that a yeast strain fails to properly form replisomes it is very likely that the genes that might be mutated are both Cdc6 and Cdt1. Cdc6 and ORC are the genes that send the signal to the yeast to start the replisome formation, and Cdt1 is a DNA replication factor that if it is mutated it could cause that yeast is not able to form the replisome.
Answer:
they provide the body with energy
Explanation:
Carbohydrates are your body's main source of energy: They help fuel your brain, kidneys, heart muscles, and central nervous system. For instance, fiber is a carbohydrate that aids in digestion, helps you feel full, and keeps blood cholesterol levels in check.
