What would be the end result of mitosis if the DNA did not replicate during interphase?
Answer: If cytokinesis took place before mitosis, chromosomes would be divided haphazardly, resulting in a defective cell. ... If chromosomes did not replicate during interphase, each new cell would receive only half the information needed to function properly.
Explanation:
The Formation of the new cell from the old cell is called cell division.
There are two types of cell division, these are as follows:-
MitosisMeiosisThe formation of the new DNA from the old DNA is called replication. The enzymes responsible for the formation of the new DNA is called DNA polymerase.
During the cell division, the DNA doubles its amount at the S phase of the interphase. If in this phase the DNA will not duplicate then at the telophase one cell has no chromosome and become the case of the nullsomy.

5. Why won't there ever be a "super" predator able to capture prey 100% of the time?
A perfect super predator is a concept that can never become a reality due to the natural process of evolution.
Throughout the ages, many predators have come and gone. The long-extinct megalodon was one of the most ferocious predators to ever live, whilst the Dragonfly boasts the highest success rate per hunt at 95%. Despite the impressive statistics, no predator has ever managed to achieve a kill rate of 100%.
This is in part due to the nature of evolution and the predator-prey relationship. The predator-prey relationship forces the advancement of evolution for each species through natural selection. The prey will evolve to become better suited for survival by evolving traits to help them escape, meaning that until the predator does the same in order to once again be able to capture the prey, it will fail during hunts. This endless cycle of predator and prey dynamic makes a 100% success rate during hunts impossible.

What releases acetylcholine at ganglia and Target?
Acetylcholine is released by preganglionic neurons on postganglionic neurons, which are typically found close to the target organs. Despite some also releasing nitric oxide, postganglionic neurons typically release acetylcholine onto their target organs.
Neurochemical acetylcholine performs a wide range of tasks throughout the body's organ systems, including the brain. More specifically, it is a neurotransmitter that is produced by neurons and functions as a chemical message that enables communication between neurons and other specialised cells like myocytes and cells in glandular tissues. Cholinergic tissues are those in the body that employ or respond to this chemical messenger. A group of substances known as anticholinergics also prevent acetylcholine from acting on tissues. Although ACh functions as a neurotransmitter throughout the body, it is most frequently connected to the neuromuscular junction.

The pentose phosphate pathway provides a number of critical functions including production of ribose-5-phost v that is vital for synthesis of nucleotides and Y. This pathway is divided into oxidative and non-oxidative steps. The latter steps are directly involved in NADF v If NAD+ v levels are high, . flux through the pentose phosphate pathway is promoted by allosteric regulation of glucose-6-phosphate dehydrogenase. If reducing equivalents derived form the pentose phosphate pathway are high, glucose-6-phosphate is directed toward glycolysis
The pentose phosphate pathway is a highly regulated metabolic pathway that can be adjusted based on the cellular needs for energy and reducing equivalents.
The pentose phosphate pathway plays a crucial role in the production of ribose-5-phosphate which is essential for the synthesis of nucleotides and NADPH. The pathway is divided into two parts, oxidative and non-oxidative steps. The non-oxidative steps are directly involved in NADPH production and do not involve the generation of ATP, unlike glycolysis. When NAD+ levels are high, flux through the pentose phosphate pathway is increased due to allosteric regulation of glucose-6-phosphate dehydrogenase. However, if reducing equivalents derived from the pathway are high, glucose-6-phosphate is directed towards glycolysis.

What is a divergent boundary? Name one example of a divergent boundary.
Answer:
In plate tectonics, a divergent boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts, which eventually become rift valleys. The mid-Atlantic ridge is an example of a divergent boundary, where the Eurasian Plate that covers all of Europe separates from the North American Plate. This underwater mountain range is constantly growing as new crust is formed. Further up that same boundary, it passes through Iceland.

Answer:
Although animal and plant cells are surprisingly similar, most of the difference between them is in their organelles. For example, plant cells have all the organelles found in animal cells plus:
Cell wall - this is a cellular structure outside of the cell membrane that gives structure to the cell, so it can have rigidness and maintain its shape.Chloroplast - this organelle captures the energy from the sunlight and converts it into chemical energy.Vacuoles - (these are present in animal cells too but are very rare) this organelle is common in plant cells and store water, waste products, food, etc.In red blood cells, lactate is continually produced as a consequence of their anaerobic metabolism. What is the energetic cost (to the liver) in ATP of converting this lactate back to glucose, per molecule of glucose generated?
The energetic cost of converting lactate back to glucose per molecule of glucose generated is 6 ATPs.
Lactate is produced by anaerobic respiration in muscles when oxygen demand exceeds supply, causing fatigue. The liver converts the lactate back to glucose, which muscles can utilize for further energy production. There are two main pathways that produce ATP in human cells: aerobic respiration (requiring oxygen) and anaerobic respiration (not requiring oxygen).
During anaerobic respiration, energy is obtained from glucose without the use of oxygen. As a result of anaerobic metabolism, red blood cells generate lactate. Red blood cells are the only mammalian cells that lack mitochondria and consequently depend solely on anaerobic metabolism for energy production. This reliance on anaerobic metabolism has significant consequences, with lactate being continually produced as a byproduct.
The liver is responsible for converting lactate back to glucose in a process known as gluconeogenesis. It is an ATP-intensive process that consumes 6 ATP molecules per molecule of glucose generated, according to research.

Show how artificial selection could be used to develop a new breed of wheat with higher fiber content
Answer:
get wheat that has the desired content (in this case high fiber content)
breed them
amongst the offsprings/ wheat produced, select the ones with highest fiber content
breed them
repeat this process for many generations
Explanation:
Artificial selection is a process of selective breeding where humans choose certain traits to breed for in plants or animals.
What would happen in case of wheat?In the case of wheat, we could use artificial selection to develop a new breed of wheat with higher fiber content by selecting individual plants with the desired traits and breeding them together over several generations.
Below are the steps:
Identify wheat plants with higher fiber content: The first step would be to identify individual wheat plants that have naturally higher fiber content. This could be done by analyzing the fiber content of different varieties of wheat and selecting those with the highest fiber content.
Crossbreed the selected plants: Once we have identified wheat plants with high fiber content, we can crossbreed them to create a new hybrid variety. This involves taking the pollen from one plant and fertilizing the flowers of another plant with it. The resulting seeds will have a mix of genetic traits from both parent plants.
Select the desired traits in the hybrid plants: After the hybrid plants have grown, we would need to evaluate them for their fiber content. We would select the plants with the highest fiber content and use them as parents for the next generation of plants.
Repeat this process for several generations: The process of selective breeding would be repeated over several generations, with each generation being evaluated for fiber content and only the plants with the highest fiber content being used for breeding. This would increase the likelihood of producing a new wheat variety with consistently high fiber content.
Test and refine the new wheat variety: Once a new wheat variety with higher fiber content has been produced, it would need to be tested for its nutritional value, taste, and other characteristics. If the new variety meets the desired criteria, it could be released for commercial production.
In summary, artificial selection can be used to develop a new breed of wheat with higher fiber content by selectively breeding individual plants with high fiber content and repeating the process over several generations until a new variety with consistently high fiber content is produced.
