The key difference is that aerobic respiration requires oxygen, and anaerobic respiration does not.
Aerobic respiration in a cell is when glucose breaks down with help of oxygen and yields carbon dioxide, water, and with the release of energy. Thus end products are [tex]CO_2}[/tex] and [tex]H_{2}O[/tex] .The process of releasing energy takes a much longer time. Example it occurs in plants and animals.
Anaerobic respiration in a cell, is the process of breaking down glucose without the use of oxygen then it yields to the end products [tex]CO_{2}[/tex] (carbon dioxide), alcohol and energy. It is a fast process. Example human muscle cells, and bacteria.
The equation for aerobic cellular respiration
[tex]C_{6} H_{12} O_{6} + 6O_{2}[/tex] ⇒ [tex]6CO_{2} + 6H_{2}O[/tex] + ATP(energy)
Glucose + oxygen ⇒ carbon dioxide + water +energy.

Building and sporulation are forms of __ reproduction
Answer: Asexual Reproduction
Explanation:
Budding and spore formation are two types of asexual reproduction methods. Hence, gamete formation and fertilization do not occur in both types. Both cases involve a single organism or a parent. Also, the offspring is genetically identical to that of the parent in both methods.
Give the order of the following events from earliest to most recent.1. Multicellularity2. Earliest Eukaryotic cells3. First Plants4. Formation of the earth5. First Primates6. First mammals7. Earliest prokaryotic cells8. First reptiles
The first event would be the formation of the earth, since in the beginning, conditions were so extreme that life was not possible. The next event would be the origin of life which occurred with the first prokaryotic cells since they are simple cells in structure. Later, there would be eukaryotes, more complex cells, with a nucleus and other organelles such as mitochondria. Eventually, the interaction between cells gave rise to multicellularity and with this, the multicellular organisms were formed, the first ones being plants, followed by reptiles in the Carboniferous and mammals in the Jurassic period. And because primates are mammals, they would be in the last place.
When two gametes (such as an egg and sperm) combine, the process is known asasexual reproduction.embryogenesis.fertilization.parthenogenesis.
When these two gametes (an egg and a sperm) combine with each other, the process is known as fertilization (as we can see in the third answer option), and this is achieved by these two sexual cells by a set of physiological reactions in which both cells are involved, for example, they can chemically attract between each other. After this process, also known as fecundation, there would be the formation of a zygote, which will end in the formation of an embryo after embryogenesis. We can see this graphically in the picture below, where there're a sperm and an egg with their parts.

facilitated diffusion across a biological membrane requires ______ and moves a substance ______ its concentration gradient.
Facilitated diffusion is the process by which molecules diffuse across the plasma membrane with the assistance of membrane proteins like channels and carriers.
What main function of facilitated diffusion in membrane?Diffusion is the flow of chemicals across a biological membrane from an area of higher concentration to one of lower concentration, and it is facilitated by the usage of a transport molecule.
Because substances move in the direction of their concentration gradient, chemical energy is not directly needed.
Solutes diffuse through transport proteins in the plasma membrane when their diffusion is facilitated. A form of passive transport is facilitated diffusion.
Therefore, facilitated diffusion across a biological membrane requires transport proteins and moves a substance down its concentration gradient.

In the catabolic pathways, which two molecules are major electron acceptors? After they accept electrons, which electron carriers do they become? What is the primary function of the electron carriers?
The two molecules that are major electron acceptors in the catabolic pathways are NAD⁺ and FAD⁺, whereas NADH and FADH₂ can be considered as electron carriers. They play a fundamental role to produce energy as ATP.
What are electron carriers?The electron carriers are specific molecules that act during cellular respiration in order produce Adenosine triphosphate from ADP and phosphate, which is the energy coin of the cell.
Therefore, with this data, we can see that the electron carriers such as NADH and FADH₂ are fundamental for producing ATP, while NAD⁺ and FAD⁺ accept electrons during this process.

In a respiration experiment we are measuring the rate alcoholic Fermentation in yeast by measuring the amount of CO2 produced Please assist with following questions
Answer and explanation:
1. sources of error- in the experiment, the amount of carbon dioxide released by east is monitored, a source of error could be the carbon dioxide present in the atmosphere which would interfere with the results.
2. baking recipes add sugars and molasses to provide carbohydrates for the yeast. this acts as a source of energy for the fermentation process.
3. the respiration of yeast could be monitored by measured the amount of sugar used or by measuring the amount of ethanol produced in the respiration process
4. high concentrations of sugar my inhibit yeast activity most likely because of the high osmotic concentration which prevents yeast from getting enough water for growth. as the osmotic concentration increases a yeast cell will reach a pont where water moves out of the cell.

What are transposable elements and what is their significance?
Transposable elements are DNA sequences, genes. With the capacity to move inside the genome, that is to say, they can change their position in the genome by themselves. Due to this ability to change position, they have been widely studied, although many times insert themselves on inactive genomic regions, they have contributed to genetic diversity and generating polymorphisms, which in turn have an impact on the evolution. Also in a low percentage of cases can generate genetic illnesses in early embryonal states, like some ehemofilias or leukemias.
Explain one environmental drawback, not related to water use, of using the franking process to extract natural gas from shale.
One environmental drawback of using the franking process to extract natural gas from shale, is air pollution.
Methane is a main component of natural gas and is 25 times more potent in trapping heat in the atmosphere than carbon dioxide. A number of other air contaminants are released through the various drilling procedures, including construction and operation of the well site, transport of the materials and equipment, and disposal of the waste. Some of the pollutants released by drilling include: benzene, toluene, xylene and ethyl benzene (BTEX), particulate matter and dust, ground level ozone, or smog, nitrogen oxides, carbon monoxide, formaldehyde and metals contained in diesel fuel combustion---with exposure to these pollutants known to cause short-term illness, cancer, organ damage, nervous system disorders and birth defects or even death .

Mutations can affect genes that control how a cell divides. This can result in cancerous tumors. A mutation that is not detected and repaired by the cell would produce which of these results? A. an interruption in the process of mitosis B. an interruption in the process of mitosis C. undifferentiated cell division D. uncontrolled cell division
All cancers begin with a gene mutation giving rise to a faulty protein participating in cell reproduction, even if it is a minor change that occured in this protein. The major problem is that the cell will divide itself nonstop, forming a mass of mutated cells (a tumor). If they start to divide in an undifferentiated way, it can even access other tissues and becom a more serious problem. But, in order to define what causes a tumor at first, the uncontrolled cell division is the beginning of it all.
Therefore, the correct answer is D. uncontrolled cell division
