This is accomplished by the process of DNA replication. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis.
When a cell divides, it is important that each daughter cell receives an identical copy of the DNA synthesis .An indication of how DNA gets duplicated was given by the clarification of the double helix's structure. Recall that cytosine pairs with guanine while adenine pairs with thymine. The two strands are so complimentary to one another. For instance, a complimentary DNA strand will have the nucleotide sequence TCAGTACT for a strand of DNA having the nucleotide sequence AGTCATA.The elucidation of the structure of the double helix gave a hint of how DNA is copied.

The level of organization that reflects the interactions between organ systems is the organism.
What is Organism ?In biology, an organism is any organic, living system that functions as an individual entity. All organisms are composed of cells. Organisms are classified by taxonomy into groups such as multicellular animals, plants, and fungi; or unicellular microorganisms such as protists, bacteria, and archaea.
Producers, consumers, herbivores, carnivores, omnivores, scavengers, parasites, predators, and decomposers are only a few of the various sorts of creatures or organisms.
There are many different kinds of organisms on Earth, some of which are complex, such as plants and animals, and which are multicellular because they include a lot of cells.
But not every organism is the same. Some, like bacteria or algae, are distinguished by having just one cell.However, not every organism has the same kind of cell. Prokaryotic cells, or cells without a clearly defined nucleus, are present in some. However, not every organism has the same kind of cell.

● Hypothesis: Revise 1
To help your investigation, here is some more data about the farm.
How should I include my data?? Will give points and I picked natural selection
To write an inclusive hypothesis from investigation, it should be structured with Mechanism of Evolution, Hypothesis and Data.
How to hypothesize?Mechanism of Evolution
The mechanism of evolution that I think caused the increase in FQ resistance is natural selection. Natural selection is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce. In this case, the bacteria that are resistant to FQ are more likely to survive and reproduce because they are not killed by the drug. This means that the population of bacteria will become more resistant to FQ over time.
Hypothesis
My hypothesis is that the increase in FQ resistance in the bacteria on the farm is due to natural selection. I believe that this is because the bacteria that are resistant to FQ are more likely to survive and reproduce, which means that the population of bacteria will become more resistant to FQ over time.
Data
The new data supports my hypothesis because it shows that the number of bacteria that are resistant to FQ has increased. The data also shows that the bacteria that are resistant to FQ are more likely to be found in the environment where the FQ is being used. This suggests that the bacteria are evolving to become resistant to the FQ.
How to Include the Data
You can include the data in your hypothesis by stating that the increase in FQ resistance is due to the fact that the bacteria that are resistant to FQ are more likely to survive and reproduce. You can also include the data by showing a graph of the number of bacteria that are resistant to FQ over time.
This is an example of how to include the data in the hypothesis:

Answer:
Yes it does
Explanation:
thank you
because their internal osmolarity is similar to that of seawater, osmoconformers . multiple choice question. tend not to lose or gain water by osmosis tend to gain water by osmosis tend to lose water by osmosis
Because their internal osmolarity is similar to that of seawater, osmoconformers tend not to lose or gain water by osmosis. Thus, the correct option is A.
What is an osmoconformer?
An osmoconformer is an animal that is iso-osmotic with its external environment. All osmoconformers are marine animals. And, because an osmoconformer's internal osmolarity is the same as that of its external environment, there is no tendency to gain or lose water.
Most of the marine invertebrates including starfish, crabs, jellyfish, lobsters, sea squirts, and scallops are osmoconformers. Such organisms do not need to expend as much energy as osmoregulators in order to regulate ion gradients in the water.
Therefore, the correct option is A.

how do hurricanes cause tornadoes?
Answer:
This is called wind shear, and it can induce a spinning movement in the air. At first this creates a spinning cylinder of air that is parallel to the surface. But as with any thunderstorm, the convective cells in a hurricane create strong updrafts. These can tilt the spinning air upright; a tornado is born.
the combining form that means hump (increased convexity) of the spine is
The combining form that means hump (increased convexity) of the spine is Kyphosis. It is a condition that can affect people of all ages, but is most common in older adults.
Kyphosis can be caused by a variety of factors, such as poor posture, aging, osteoporosis, and tumors. It is usually characterized by an excessive arch in the upper back, resulting in a rounded or humped spine. In severe cases, the spine may be bent in an extreme arch, causing pain, difficulty breathing, and a visible deformity. People with kyphosis often find that their head is bent forward and their chest is sunken.
Treatment for kyphosis depends on the severity and cause of the condition, but may include physical therapy, surgery, or bracing. If left untreated, kyphosis can lead to further medical complications and even disability. Kyphosis is a condition that should not be ignored, as it can have serious consequences if not treated properly.

This simulation shows only the changes in energy that cause the motion of the skateboarder. What energy
transformations are going on within the skateboarder's body during this process?
As the skateboarder moves, several energy transformations take place within their body. Some of the energy transformations include:
1. Chemical energy to kinetic energy: When the skateboarder pushes off the ground, the energy stored in the chemical bonds of their muscles is converted into kinetic energy, which is responsible for their motion.
2. Kinetic energy to gravitational potential energy: As the skateboarder moves up a ramp, their kinetic energy is converted into gravitational potential energy.
3. Gravitational potential energy to kinetic energy: When the skateboarder moves down the ramp, the gravitational potential energy is converted back into kinetic energy.
4. Kinetic energy to thermal energy: As the skateboarder moves, they also experience frictional forces which convert some of their kinetic energy into thermal energy.
5. Chemical energy to thermal energy: The continuous movement of the skateboarder requires the energy stored in their muscles to be converted into thermal energy, which is released as heat.
I hope that the assistance I provided was helpful.
The motion of the skateboarder is powered by energy transformations that occur within their body. As the skateboarder moves, their body converts stored chemical energy (from food) into kinetic energy, which is the energy of motion. This conversion happens through a series of complex biochemical processes that occur within the skateboarder's muscles.
When the skateboarder pushes off the ground, their leg muscles contract, converting chemical energy stored in the form of ATP (adenosine triphosphate) into kinetic energy as the legs move and the skateboarder accelerates. As the skateboarder continues to move, the muscles in their body work together to maintain balance and control, converting chemical energy into kinetic energy and potential energy as the skateboarder jumps, turns, and performs tricks.
Additionally, the skateboarder's body also experiences other forms of energy transformation during this process. For example, as the skateboarder moves, their body generates heat through metabolic processes, which is a form of thermal energy. The skateboarder also loses energy through friction with the ground and air resistance, which is converted into heat and sound energy.
In summary, the motion of the skateboarder is powered by a series of complex energy transformations that occur within their body. These transformations involve the conversion of stored chemical energy into kinetic and potential energy, as well as the generation of heat and sound energy through friction and air resistance.
Individual organisms of the same species are not identical. They have different genes and grow up in different environments. What is the word used to describe their differences?.
Answer:
The differences in characteristics between individuals of the same species is called variation . Some variation is passed on from parents to offspring, via genes during reproduction. ... Some variation is the result of differences in the surroundings, or what an individual does. This is called environmental variation.
The word used for describing their differences is variation.
What is genetic variation?Genetic variation is the variance in DNA sequences among members of a population. Germ cells, such as sperm and eggs, as well as somatic (all other) cells, are subject to variation. The one and only variation that develops in germ cells are inheritable, which has an impact on population dynamics and, eventually, evolution. Major causes of variation include recombination and mutation.
Genetic variety first appeared as a result of mutations. A mutation is a type of DNA sequence change that is irreversible. When a mistake in DNA replication occurs and is not fixed by DNA repair enzymes, de novo (new) mutations take place.
Another important source of genetic diversity is recombination. Each of us is made up of a combination of our parents' genetic material. When homologous DNA strands align and cross across during recombination, this genetic material is combined. Maternal and paternal DNA is effectively "shuffled" during recombination, resulting in novel variant combinations in the daughter germ cells.
Therefore, the differences in the organisms are called variations.

Explain how Photosynthesis and Cellular Respiration are important in your everyday life. Be Scientific! 5-6 sentences!
Answer:
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathway through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels.
Photosynthesis is a very important process in plants. It helps in the formation of glucose in plants. Cellular respiration takes place in human beings.
What is energy?Energy is the ability to do work. All living organisms require energy to do work. Energy is transformed to chemical energy in plant cells through a process called photosynthesis.
Plants utilise the chemical energy stored during photosynthesis in their cellular respiration for essential life functions. Energy is changed during both photosynthesis and cellular respiration.
The light-dependent and light-independent processes of photosynthesis are also important for plant management.
Therefore, Photosynthesis is a very important process in plants. It helps in the formation of glucose in plants. Cellular respiration takes place in human beings.

The enzyme that converts pyruvate into acetyl-CoA requires vitamin B 1, also called thiamine. Vitamin B 1 has to be obtained through the diet. At what phase would cellular respiration come to a halt without B 1?
The enzyme that converts pyruvate into acetyl-CoA requires vitamin B1, also known as thiamine. Vitamin B1 is necessary for the normal functioning of the nervous system, the heart, and the gastrointestinal tract.
In cellular respiration, thiamine is required for the conversion of pyruvate to acetyl-CoA, which is an essential step. This occurs in the first stage of cellular respiration known as glycolysis. The pyruvate molecule produced in glycolysis moves into the mitochondrial matrix in the second stage, where it is converted to acetyl-CoA and carbon dioxide by the enzyme pyruvate dehydrogenase.
Acetyl-CoA then enters the citric acid cycle (Krebs cycle) to produce ATP, which is the energy source for cells. Cellular respiration would come to a halt without vitamin B1 during the conversion of pyruvate to acetyl-CoA. Acetyl-CoA is a precursor molecule that is necessary for the citric acid cycle. When vitamin B1 is not present, pyruvate will not be converted to acetyl-CoA.
This, in turn, prevents the citric acid cycle from starting, which would cause cellular respiration to stop. As a result, vitamin B1 is required for the efficient metabolism of glucose in cells. Therefore, vitamin B1 plays a critical role in energy metabolism, and its absence of it can cause serious health issues.
