Answer:
Aerobic to lactic acid fermentation pathway
Explanation:
ATP, which is the usable form of energy in living cells, is obtained via a process called RESPIRATION. However, aerobic respiration requires a constant supply of oxygen to occur. Hence, during an intense exercise where the supply of oxygen is low, the muscle cell has to switch from the respiration pathway that requires oxygen to one that doesn't.
Fermentation is a kind of cellular respiration that does not require oxygen to occur. In the muscle cells of animals (humans inclusive), lactic acid is the product of the fermentation process, hence, it is called LACTIC ACID FERMENTATION. This means that the muscle cells, in a low supply of oxygen, will switch from AEROBIC to LACTIC ACID fermentation pathway.
Why can't cellular respiration occur without photosynthesis? (2 points)
Photosynthesis produces carbon dioxide, which is used in cellular respiration.
Cellular respiration requires carbon dioxide, which is produced by photosynthesis
Photosynthesis produces ADP, which is used in cellular respiration.

B. Helicase connects the floating nucleotides to the template strands.
C. Helicase checks the base pairs in each new strand of DNA.
D. Helicase bonds together pieces of DNA as new strands form.
Answer:DNA helicases are also called molecular motors. They unwind the DNA with the help of ATP hydrolysis, and thus facilitate the replication and transcription processes. ... Studies have suggested that DNA helicases may play a role in plant DNA recombination, as it is prominent during the meiotic prophase of plants.
Explanation:
Role played by Helicase in DNA Replication is to break down the hydrogen bonds and unwinds a section of DNA.
What is DNA?
DNA, or deoxyribonucleic acid, is the hereditary material in humans located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Mitochondria are structures within cells that convert the energy from food into a form that cells can use.
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people.
The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences.
What is DNA Replication?In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule.
DNA replication occurs in all living organisms acting as the most essential part for biological inheritance and it is essential for cell division during growth and repair of damaged tissues, while it also ensures that each of the new cells receives its own copy of the DNA.
The cell possesses the distinctive property of division, which makes replication of DNA essential.
DNA is made up of a double helix of two complementary strands. The double helix describes the appearance of a double-stranded DNA which is composed of two linear strands running opposite to each other and twist together to form.
During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication.
As a result of semi-conservative replication, the new helix will be composed of an original DNA strand as well as a newly synthesized strand.
Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.
What is the role of Helicases in DNA Replication?Helicases are enzymes that bind and remodel nucleic acid or nucleic acid protein complexes.
Helicases are of two types- DNA Helicases and RNA Helicases.
Role of Helicases:
- Separate the double stranded DNA into single one to allow copying.
- Initiate synthesis at the origin of unwinding
- Helicases use the energy stored in a molecule called ATP, which serves as the energy currency of cells, to break the bonds.
- DNA helicases also function in other cellular processes where double-stranded DNA must be separated, including DNA repair and transcription.
- RNA helicases are involved in shaping the form of RNA molecules, during all processes involving RNA, such as transcription, splicing, and translation.

An amoeba is a single-celled organism that feeds on algae, plant cells, and bacteria. When an amoeba feeds, it first makes contact with the food particle. Next, the amoeba starts to surround the particle. Once the particle is completely engulfed, it is surrounded by a layer of the amoeba's membrane, forming a vesicle. The pH in the vesicle is then lowered and the contents are degraded.
What type of transport is involved in this process?
A.
endocytosis
B.
diffusion
C.
passive transport
D.
exocytosis
Answer:
A. endocytosis
Explanation:
Endocytosis is the type of transport that is involved in this process because it engulf the food material. Amoeba engulfs food particles with the help of its pseudopodia which are the projections of cell membranes. A food vacuole is formed around the food particle. This process of engulfing a matter by the projections of the cell membrane to form a vacuole is called endocytosis.

Answer:
This question lacks options, options are:
a) classical conditioning
b) observational learning
c) spontaneous recovery
d) operant conditioning.
The correct answer is a.
Explanation:
The classical conditioning theory derives from the experiments of the Russian physiologist Ivan Pavlov, he hypothesized that when any stimulus predicts the occurrence of another stimulus that triggers an automatic response, that first stimulus would acquire the ability to trigger that response, in other words , is a type of learning according to which an originally neutral stimulus, which does not provoke a response, becomes able to provoke it thanks to the associative connection of this stimulus with the stimulus that normally provokes said response. The conditioning of the immune response is built on the same principles of the classical conditioning paradigm described by Ivan P. Pavlov in which an environmental stimulus that by itself does not produce any immune reaction (conditioned stimulus), is associated with substances that stimulate or they suppress immune function (unconditioned stimulus), and finally, by presenting the conditioned stimulus alone, trigger the appropriate immune response.

A founding population usually has lower genetic diversity than the original population it came from. For those alleles that are shared by the two populations, how are allele frequencies different (or similar)
Answer:
In the founding population, the allele frequency is different from the original bigger-sized population. The size of the new population affects this difference even more. Some of the alleles will tend to increase, while some others will tend to decrease in frequency.
Explanation:
Genetic drift is an evolutive force. It is the random change that occurs in the allelic frequency of a population through generations. Its effects are harder in a small-sized population, meaning that the magnitude of this change is inversely related to the size of the original population.
Genetic drift results in some alleles loss -including the beneficial ones-, while some other alleles get fixated. Low-frequency alleles are the most likely to be lost. The changes produced by genetic drift accumulate in time and results in a loss of genetic variability within a population.
Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure -bottleneck effect- or because of a population split -founder effect-. The bottleneck effect most likely affects smaller populations.
Founder effect refers to the origin of a new population from only a few individuals that are coming from a bigger-sized population. These founder individuals, which are carrying some of the genes of the original population, settle down in a new area and reproduce. The new and small population might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be lost by complete. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced, and there exists the possibility of developing a peculiar allelic composition. When the number of individuals that originated the new population is low, the founder effect will be very extreme because the genetic drift effects are inversely proportional to the original number of individuals.
