Answers
When human cells may produce ATP, CO2, plus ethanol (ethyl alcohol) as a source of energy through anaerobic glucose catabolism.
What serves as the primary function of glucose catabolism?Energy production is the major goal of glucose catabolism. This energy is present in the form of ATP, a molecule that acts as a unit of account for energy in cells. When the ATP is hydrolyzed, a significant amount of energy is released, and this energy is then used to power endergonic processes like growth.

Calculate the heat energy of 100 g of water that has its temperature increased by 10C . The specific heat of water is 4.18 J/gC
Answers
Answer:
4180 Joules
Explanation:
Multiply 100g by the 10c to get the amount of degrees heating the amount of grams, which is 1000.
Specific heat is how much energy it takes to heat 1 gram 1 degree celcius, which it took 1000 of.
1000* specific heat for water = Total heat energy
1000*4.18J=4180 J
It took 4180 Joules of energy to heat up 100g of water by 10 C
this video shows the movement of oil near the site of the 2010 oil spill. what happens to the oil after it’s spilled.
Answers
Oil spill has detrimental effects on the environment.
During transportation of oil, the leakage of oil that occurs in the water bodies, specifically in the oceans and seas is referred to as oil spill.
This spilled oil floats on the surface of water. This oil has effects on aquatic animals as well as the birds that hover around the water bodies. For instance, if the feathers of the seabirds get oiled, the birds can die of hypothermia. Many fishes and planktons die because of the oil spilled.
The oil droplets present on the surface are degraded by the process of photooxidation that happens due to exposure to light and oxygen. This also results in the formation of free radicals that are harmful to the water body as well as to the organisms present in water.

Answers
Answer: A
Explanation: The correct answer is A) Prophase. In the mitotic phase of the cell cycle, prophase is the first stage. During prophase, the chromatin condenses to form visible chromosomes, the nuclear membrane breaks down, and the mitotic spindle begins to form.
Mitosis refers to Cell/cytoplasmic division, whereas cytokinesis refers to cell plate formation in animal cells.
Mitosis is classification of the cell rotation which is from cell division chapter. During cell division by mitosis, genetically identical cells with a conserved total number of chromosomes are formed.
Therefore, mitosis is also called equal division. Mitosis is process in an interphase S phase during which DNA replication it happens very less, often followed by telephase and cytokinesis.
This divides the cell's cytoplasm, organelles, and plasma membrane into two new cells containing approximately equal proportions of these cellular components. Cytokinesis begins during or after the late stages of nuclear division in mitosis and meiosis.

what rna molecule(s) could be transcribed from this piece of dna?
Answers
The RNA molecules could be transcribed from DNA are mRNA, tRNA, and rRNA
The RNA molecules are complementary to the DNA template strand and have the same sequence as the non-template strand, except that the base thymine is replaced with uracil. The types of RNA molecules that can be transcribed from this piece of DNA include messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). mRNA carries the genetic information from the DNA to the ribosomes for translation into proteins.
tRNA helps to decode the genetic information in mRNA and delivers the corresponding amino acids to the ribosomes during protein synthesis. rRNA is a component of the ribosome and plays a crucial role in the translation process. Therefore, depending on the exact sequence of this DNA piece, one or more of these RNA molecules such as mRNA, tRNA, and rRNA could be transcribed from it, and they all have specific functions in protein synthesis.

What is the role of photosynthesis and cellular respiration in the cycling of matter and the flow of energy through the ecosystem
Answers
Answer:Cellular respiration in plants and animals involve chemical reactions with oxygen that release stored energy. ... Plants, algae, and many microorganisms use the energy from light, carbon dioxide from the atmosphere, and water to make sugars (food) through the process of photosynthesis, which also releases oxygen.
Explanation:
hope it helps :)
The role of photosynthesis and cellular respiration in the cycling of matter and the flow of energy through the ecosystem is the following:
The fundamental energy source of all ecosystems is the Sun, which sends a large amount of energy to Earth in the form of light and heat.
The various green plants use energy from the sun, water and nutrients from the soil, and carbon dioxide from the air to produce organic matter.
The process by which light is used as an energy source to transform CO2 into organic compounds essential for life is called photosynthesis.
The manufactured organic matter is used by the photosynthetic organisms themselves for the maintenance of their vital processes through cellular respiration.
Energy, once solar energy is transformed by producers into chemical energy by making organic matter in photosynthesis, is transmitted along with matter.
In each transfer of energy, between the different types of organisms there is a release of energy to the environment, in the form of heat.
On the contrary, matter flows cyclically, chemical elements are transferred between living beings and in the physical environment of each ecosystem.
Therefore, we can conclude that the role of photosynthesis in the cycling of matter and the flow of energy through the ecosystem is to produce the transformation not only of inorganic into organic matter, but also of light energy into chemical binding energy, oxygen is released as a waste product and is used by most organisms for cellular respiration.

The correct answer is B. Bog.
A bog is a type of freshwater ecosystem that has very low to no water flow. It is a wetland that is characterized by a thick layer of peat, which is formed from dead and decaying plant material. Bogs receive most of their water from precipitation, rather than from surface or groundwater sources. The lack of water flow in a bog means that nutrients are not replenished as quickly as they are in other freshwater ecosystems, which can limit the productivity of the ecosystem.

Answers
When an electron has been excited to a higher energy state, excited electrons are transferred to electron acceptors in the chloroplast.
An electron can return to its original level after being stimulated to a higher energy state and reemit the light as fluorescence. Chlorophyll fluoresces brightly when exposed to a strong red or blue light after being extracted in solution. However, there is no fluorescence when the red or blue light is turned on and the chlorophyll is contained inside chloroplasts. This suggests that energized electrons are likely transported to chloroplast electron acceptors.

People who lose their sense of taste may also lose interest in eating. Which of the following is involved in the perception of tastes?
Taste cells for sweet are only located at the anterior tip of the tongue.
Transduction of sour and sweet tastes involves activation of a G protein called gustducin.
Afferent impulses related to taste are carried to from the tongue to the CNS by the trigeminal nerve (cranial nerve V).
Much of what is perceived as a taste defect may actually be a defect in olfaction, which causes foods and beverages to taste differently.
Answers
Answer: Transduction of sour and sweet tastes involves activation of a G protein called gustducin.
Explanation: The correct option is "Transduction of sour and sweet tastes involves activation of a G protein called gustducin." This option correctly describes the process of transduction, which is the conversion of a sensory stimulus into an electrical signal that can be interpreted by the brain. Gustducin is a type of G protein that is involved in the transduction of sweet and umami (savory) tastes, as well as sour tastes to some extent. Therefore, this option is directly involved in the perception of tastes.
Option A is incorrect because taste cells for sweet are not only located at the anterior tip of the tongue; rather, they are spread throughout the tongue. Option C is incorrect because afferent impulses related to taste are carried to the CNS by three different cranial nerves - facial (VII), glossopharyngeal (IX), and vagus (X) - and not trigeminal nerve (V). Option D is partially correct because olfaction does play a role in taste perception, but it does not explain the specific mechanism of taste transduction as mentioned in option B.

The root apical meristem produces a root cap to protect the radicle, which emerges first from the seed to improve water uptake.
What is germination?Germination is the process through which a seed, spore, or other reproductive body typically breaks dormancy and begins the process of sprouting.
The embryo absorbs water and expands cells during seed germination. After water intake, or imbibition, respiration increases and metabolic functions, paused or greatly decreased during dormancy, resume. These processes are linked to structural changes in embryo cell organelles (metabolic membranes).
The radicle, which is the primary embryonic root, emerges from the seed first in order to maximize the plant's capacity to absorb water. The root cap, which is produced by the root apical meristem, serves to shield the radicle.
