What type of bond would join two amino acid subunits? peptide bond How do you combine amino acids? Peptide Bonds Each amino acid is attached to another amino acid by a covalent bond, known as a peptide bond. When two amino acids are covalently attached by a peptide bond, the carboxyl group of one amino […]

How do oceans affect the water cycle? The ocean plays a key role in this vital cycle of water. Besides affecting the amount of atmospheric water vapor and hence rainfall, evaporation from the sea surface is important in the movement of heat in the climate system. Water evaporates from the surface of the ocean, mostly […]

What happens if cells divide too much? Scientists say that one parent cell, or the dividing cell, forms two identical daughter cells (kind of like twins). If the cell cycle is not carefully controlled, it can cause a disease called cancer, which causes cell division to happen too fast. A tumor can result from this […]

Which processes in the water cycle are identified by the numbered arrows? The arrows show the movement of water molecules through the water cycle. The circled numbers represent the processes that occur as the water molecules reach the different stages of the water cycle. Which two letters represent processes in the water cycle? Letters A, […]

What is the role of consumers in the food chain? Organisms interact with each other and their environment in ecosystems. The role of consumers in an ecosystem is to obtain energy by feeding on other organisms and sometimes transfer energy to other consumers. Changes that affect consumers can impact other organisms within the ecosystem. Where […]

What fruit trees can you graft together? Nearly all citrus varieties are compatible with each other for grafting. Any two varieties of fruit trees in the Prunus genus such as apple, cherry, and plums also do well when grafted together. How do you graft fruit trees? Grafting involves taking a scion or bud chip cut […]

What is the main function of the electron transport chain? The electron transport chain is used to pump protons into the intermembrane space. This establishes a proton gradient, allowing protons to be pumped through ATP synthase in order to create ATP. This method of ATP production is called oxidative phosphorylation. What is the relationship between […]

How does temperature affect thermohaline circulation? Thermohaline circulation describes the movement of ocean currents due to differences in temperature and salinity in different regions of water. Temperature and salinity change the density of water, resulting in the water to move accordingly. Cold water is usually denser than warm water (4°C is where water is densest). […]

What are the classes of angiosperms? Based on the types of cotyledon present, angiosperms are divided into two classes. They are monocotyledons and dicotyledons. The dicotyledonous angiosperms have two cotyledons in their seeds and the monocotyledonous angiosperms have one cotyledon. Which two plants are classified as angiosperms? Angiosperms represent approximately 80 percent of all known […]

Why do prokaryotes not have a nucleus? Prokaryotes do have their genomic DNA concentrated and localized to a small area within the cell (nucleoid region). So it’s not entirely accurate to say that prokaryotes don’t have a nucleus. The cell can release DNAses into the cytoplasm to degrade viral DNA, with reduced risk of degrading […]
