the breakdown of large, complex, molecules into smaller, simpler molecules is accomplished by a process known as? A. Dehydration Synthesis B. Induced Fit C. Hydrolysis D. Lock and Key Synthesis
Answer: C. Hydrolysis
Explanation:
In the process of hydrolysis, large complex molecules such as polymers are broken down into smaller, simpler molecules like monomers.
This is done through the use of water. The molecule that neds to be broken down is reacted with water and water then breaks the bonds of the complex molecule. The hydrogen ion in water goes to a molecule of the other reactant and the OH- goes to another molecule.

Need help with this question
Answer:
They can be reproduced on a human timescale ⇒ Renewable resources
Renewable resources don't take millions of years to form like non-renewable resources. This allows for them to be renewed in a relatively short time.
They take millions of years to form ⇒ Non-renewable resources
Most non-renewable resources are fossil fuels and these take millions of years to form as they are the result of the remains of dead plants and animals being compressed over those millions of years.
They are produced naturally ⇒ Both Renewable and Non-renewable
Both types of resources are produced by natural processes. Fossil fuels are dead animals and plants and renewable resources like wind and solar are natural.
They are extracted by mining ⇒ Non-renewable resources
As mentioned, fossil fuels take millions of years to form and are formed by compression. This compression happens because the dead animals and plants are buried underground. To extract the fuels therefore, they need to be mined.
Their use as an energy source is increasing because they reduce pollution ⇒ Renewable resources
Renewable sources do not cause pollution like non-renewable sources so they are a preferred option when it comes to environmental damage.
What is the derived Sl unit for quantities of energy?
A. Newton
B. Mole
C. Joule
D. Kilogram
Answer:
C. Joule
Explanation:
Energy can be defined as the ability of an individual to do work per unit time.
There are different types of energy and these includes mechanical energy, chemical energy, solar energy, electrical energy, nuclear energy, wind energy etc.
Also, there are two (2) forms of energy and these are;
I. Potential energy: it can be defined as an energy possessed by an object or body due to its position.
Mathematically, potential energy is given by the formula;
[tex] P.E = mgh[/tex]
Where;
P.E represents potential energy measured in Joules.m represents the mass of an object. g represents acceleration due to gravity measured in meters per seconds square. h represents the height measured in meters.II. Kinetic energy: it can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
[tex] K.E = \frac{1}{2}MV^{2}[/tex]
Where;
K.E represents kinetic energy measured in Joules. M represents mass measured in kilograms. V represents velocity measured in metres per seconds square.A derived unit can be defined as a unit derived through the multiplication of three (3) SI base unit; mass (kg) , length (m) and time (s).
Hence, the derived Sl unit for quantities of energy is Joules (m²kgs¯²).

All organisms need to have the proper environment for them to carry out the basic functions of life, such as nutrition. Explain why Deshawn's experiment supported this.
Answer and Explanation:
Nutrition enables the organisms to grow and reproduce. Plants require water, light, and essential nutrients to fulfill their biochemical needs. Plants obtain food in two ways. Autotrophic plants can prepare their food from water and carbon dioxide by photosynthesis in the presence of sunlight, such as green plants. Heterotrophic plants cannot prepare their food. They obtain nutrients from the host plant. Parasitic plants have no leaves and depend on their host for existence. A saprophyte plant obtains its food from dead matter. An insectivorous plant has left to digest and attract insects. Animals depend on other organisms to fulfill their nutritional needs. Animals are classified into three groups, such as herbivores, omnivores, and carnivores. Carnivores are meat eaters such as tigers and lions. Herbivores are plant eaters such as koalas, deer, and birds. Omnivores are both plants and animal eater such as chickens, humans, and bear. That why Deshawn’s experiment supports this statement is that all organisms need a proper environment to carry out essential life functions.
Answer:
Nutrition permits the organisms to develop and reproduce. Plants require water, light, and crucial vitamins to fulfill their biochemical needs. Plants acquire meals in two ways. Autotrophic plant life can put together their meals from water and carbon dioxide by means of photosynthesis in the presence of sunlight, such as inexperienced plants. Heterotrophic vegetation can't put together their food. They gain vitamins from the host plant. Parasitic flowers have no leaves and rely on their host for existence. A saprophyte plant obtains its meals from lifeless matter. An insectivorous plant has left to digest and entice insects. Animals rely on different organisms to fulfill their dietary needs. Animals are labeled into three groups, such as herbivores, omnivores, and carnivores. Carnivores are meat eaters such as tigers and lions. Herbivores are plant eaters such as koalas, deer, and birds. Omnivores are each flowers and animal eater such as chickens, humans, and bear. That why Deshawn’s test helps this assertion is that all organisms want a perfect surroundings to elevate out critical existence functions.

what gas did not appear in any measurable amount until about 2.0 BY BP?
Answer:
The correct answer is Oxygen.
Explanation:
2.0 BYBP means 2 billion year before present.
The theory of evolution holds that the the synthesis into primitive life forms of the basic chemical components of life such as carbon, nitrogen, hydrogen and oxygen occurred in an atmosphere without any oxygen.
The presence of oxygen in our plant today is explained by two processes.
They are:
Photosynthesis and One is photochemical dissociation. This refers to a reaction between the suns ultraviolet radiation and water molecules in the upper atmosphere. This photochemical reaction is said to have contributed to the oxygen in the plant today.The process of Photosynthesis which is the chief contributor of oxygen to the earths atmosphere is said to have spanned billions of years.
