Fritz has a DNA test to determine if he shoplifted from a local convenience store. The test results are inclusive. This means Fritz_____.
has an identical twin
was at the scene of the crime
is not guilty of shoplifting
has never been to the store
Answer:
stop
just use the question for that question not the whole entire thing
Explanation:
tertiary consumers
(B) primary consumers, deer, bacteria, fungi, nonliving things, tertiary
consumers
(0
producers, primary consumers, secondary consumers, tertiary consumers
D primary producers, primary consumers, secondary consumers,
carbohydrates, water
Answer:
answer is (0, or the third option
Explanation:
D is wrong cause carbohydrates is health
Catalase is an enzyme, a type of biological molecule composed mostly of protein, that serves as a catalyst to accelerate the breakdown of hydrogen peroxide into water and oxygen within living organisms.
Catalase is a type of biological molecule called an enzyme. Enzymes are macromolecules, primarily composed of proteins, that act as catalysts to accelerate chemical reactions within living organisms. They work by lowering the activation energy of the reaction they are catalyzing, thereby speeding up the reaction rate. Catalase serves a critical biological function by converting the harmful substance hydrogen peroxide into water and oxygen.
Enzymes function by binding to reactant molecules and facilitating bond changes in order to make the reaction occur more readily. However, they do not change the reactants' or products' free energy or alter the direction of the reaction. Instead, they simply reduce the activation energy required to reach the transition state of a chemical reaction.
Like all enzymes, catalase is highly specific to its substrate (the molecule it reacts with). In this case, the substrate is hydrogen peroxide. Importantly, like all catalysts, enzymes including catalase do not get consumed or modified during the reaction, making them reusable.

B.mitosis
C.fertilization
D.sexual reproduction
Answer: It would be C, fertilization
Explanation: fertilization is the basis of variability, since the two main purposes of fertilization are the combination of genes derived from both parents and the generation of a new individual with a new genetic endowment.
A Insulation
B. Structural support
C. Provide energy
D. Control metabolic functions
Lipids accomplish many different functions, such as energy provision, structure, and insulation, among others. However, they are not in control of metabolic functions. Therefore the answer is D.
--------------------------------------------
Lipids are amphipathic molecules with hydrophilic heads -negatively charged phosphate group- and hydrophobic tails.
Lipids are involved in several functions. Among others, we can mention,
In the organism, lipids constitute the energetic reserve of late or differed use. These are in the triacylglycerol form. Their caloric content is very high and represents a significant source of energystorage.
Aerobic combustion of lipids produces a great metabolic water quantity. Some desertic animals -camels- store fat in their tissues to produce water when needed.
Some other animals produce a specialized adipous tissue called brown fat. Lipidic combustion in these tissues is decoupled from oxidative phosphorylation. Most of the energy derived from combustion is used for heat production.
Hybernating animals use this brown fat to produce energy during the long hibernation periods.
Two lipidic bilayers compose the cell membrane. They are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane. They can also provide protection and isolation for specialized tissues and organs.
Lipids are involved in cell signals. They control the fluidity of membranes in the central and peripheral nervous systems, playing a role in electrical signals transmission and synapses.
