Lactic acid is produced during lactic acid fermentation, a process used by certain bacteria and animal muscle cells under low-oxygen conditions, catalyzed by lactate dehydrogenase. In muscles, lactic acid is transported to the liver for conversion back into pyruvic acid for energy.
Explanation:Lactic Acid Fermentation
Lactic acid is produced during a process known as lactic acid fermentation. This process is carried out by certain bacteria, such as those found in yogurt, and by animal muscle cells, like those in humans, during intense physical activity when there is not enough oxygen available for aerobic respiration. The key chemical reaction in this process is Pyruvic acid + NADH → lactic acid + NAD+, and it is catalyzed by the enzyme lactate dehydrogenase (LDH). In muscle cells, this process allows them to continue producing energy even when oxygen levels are low, although it can lead to the temporary accumulation of lactic acid in the muscles. Ultimately, the lactic acid must be transported via the blood to the liver, where it can be converted back into pyruvic acid and used for further energy production.

Daughter cells are quite small but grow and take on ATP during the G1 phase of interphase.
True
False
Answer: True
Explanation: During M phase, cell division takes place and two daughter cells are formed. But the size of these daughter cells is almost half the size of the mother cell. During G1 phase, the doubling of size and cell content take place. The size of the daughter cells increase to the size of the normal cell.

what is the central dogma of molecular biology
The central dogma of molecular biology describes the process by which genetic information flows from DNA to RNA to proteins. It involves transcription and translation. Understanding this process is key to understanding how cells function and regulate activities.
The central dogma of molecular biology explains the flow of genetic information within a biological system. First articulated by Francis Crick, it states that genetic information is stored in DNA, which is then transcribed into RNA. This RNA is subsequently translated into proteins, which perform most cellular functions.
This fundamental principle involves two main processes:
Transcription: DNA is used to make RNA.Translation: RNA is used to synthesize proteins.Understanding the central dogma is crucial as it encompasses how genes encoded in DNA result in functional proteins, allowing for cellular activities and regulation.

What is the process of developing a cultivated group of domesticated animal??
Animal husbandry is the process of developing a cultivated group of domesticated animals. It involves steps like selection based on desired traits and artificial selection to ensure these traits are passed down through generations. Over time, this creates a new breed of animal that is more beneficial for human use.
Explanation:The process of developing a cultivated group of domesticated animals, or animal husbandry, involves controlled breeding to highlight desirable characteristics and diminish undesirable ones. The initial step is selection, where specific animals showcasing traits such as productivity, hardiness, or gentle temperament are chosen to reproduce. Artificial selection is then applied, where humans influence the breeding and survival rates of animals based on these traits.
Over generations, these traits become common within the group, effectively creating a new line or breed of the animal that is more beneficial for human use. Examples of this process can be seen in the various breeds of dogs, cattle, and poultry that have been developed for different uses.

____ of all vertebrates are general sensors for touch, pressure, and pain. A) Olfactory receptors. B) Chemoreceptors. C) Photoreceptors. D) Mechanoreceptors.
Answer: D) Mechanoreceptors
Mechanoreceptors of all vertebrates are receptors in the skin that detect sensations of touch, pressure, and pain. Olfactory receptors detect odorants.
Chemoreceptors are for the detection of changes in blood oxygen and carbon dioxide, while photoreceptors are used for color vision.
viruses do not have the ability to reproduce on their own, they need a blank
Final answer:
Viruses require a host cell to conduct replication, as they cannot reproduce on their own due to the lack of essential components and metabolic machinery. They use the host cell's resources to produce viral particles and exhibit specificity in infecting cells that possess the required viral receptors.
Explanation:
Viruses do not have the capability to reproduce on their own; they need a host cell to facilitate the process known as replication. Viruses are not considered living organisms since they lack essential components like a plasma membrane, cytoplasm, and ribosomes. Unlike cellular life forms, they cannot perform metabolic activities or maintain homeostasis independently. Therefore, they must infect a living host, which provides the necessary cellular machinery and metabolism for the virus to produce new copies of itself.
Once inside the host cell, a virus commandeers the host's ribosomes, enzymes, ATP, and other resources to produce viral particles. Viruses show specificity in the cells they can infect, which is often determined by the presence of specific viral receptors on the surface of the host cell. This specificity depends on the host's metabolic processes and gene expression, which ensure the necessary substances for replication are available.

Where is a subduction zone most likely to from?
Answer
A subduction zone is the largest wreck scene on Earth. These lines indicate the crash within two of the planet's tectonic plates. The plates are pieces of crust that slowly move across the planet's cover over millions of years. Where two tectonic plates meet, if one or both of the plates are oceanic lithosphere, a subduction zone will form. An oceanic plate will soak back into the mantle. Remember, oceanic plates are made from mantle material at midocean ranges.
Subduction zones form at convergent plate boundaries, particularly where an oceanic plate meets a continental plate. They are areas of high seismic and volcanic activity. Examples include the Marianas Trench and the Chile-Peru trench.
Explanation:A subduction zone is most likely to form at convergent plate boundaries, specifically where an oceanic plate meets a continental plate. In this scenario, the denser oceanic plate is forced under the lighter continental plate, creating a subduction zone. Subduction zones are sites of high seismic and volcanic activity. Notable examples include the >Marianas Trench in the western Pacific Ocean and the Chile-Peru trench in the eastern Pacific Ocean.

in order to continually use the same area of land for agriculture, some farmers apply fertilizers to improve the level of nitrates in the soil. an alternative to this intensive use of fertilizer is to plow the roots of the leguminous plants back into the soil and leave the area unplanted for a season. why would a farmer use this alternative method and what would be the benefit of turning over the soil and leaving the old pant roots?
Farmers might choose to plow leguminous plant roots back into the soil and leave the area fallow to naturally replenish the soil's nutrients. This practice uses rhizobia, bacteria that fix nitrogen from the atmosphere into a usable form for plants. This alternative to synthetic fertilizers aids soil fertility and promotes sustainable farming.
Explanation:To maintain the fertility of farming lands without a constant use of fertilizers, farmers can resort to an alternative method, such as plowing leguminous plant roots back into the soil and leaving the area fallow for a season. Leguminous plants interact with soil bacteria, known as rhizobia, in a symbiotic relationship to influence nitrogen fixation. This is the transformation of atmospheric nitrogen into ammonia, a compound that plants can easily utilize. The incorporation of legume roots into soil not only provides a natural and sustainable supply of nitrogen but it also improves the overall soil fertility due to the nitrogen left behind by the root system.
Shifting toward this practice of extensive or shifting cultivation involving various plots of land serves both the environment and the farmer. For one, it minimizes the use of chemicals and thus promotes the sustainability of agricultural practices. Moreover, leaving a plot fallow for a certain period allows the soil to regenerate and accumulate fresh nutrients naturally. Furthermore, turning over the soil and leaving the old pant roots enhances the nutrient content of the topsoil, making it more fertile for the next planting season.
