What might an elevated skin temperature indicate beside a fever from a cold, flu, or other typical viral disease? How might you test for an elevated temperature?
Answer: Fever is a common symptom of illness. The Centers for Disease Control and Prevention (CDC) defines fever as a temperature above 100.4° F, though children often run higher fevers than adults.
Many types of infection can cause fever, as your body will increase temperature to effectively fight off the virus or bacteria causing the infection. These fevers will usually resolve themselves as your body works to get rid of the foreign invader.
Explanation:
Fever is one of the common symptoms of different illnesses and is also a defense mechanism of the body. A temperature above 100.4° F is considered as fever.
Fever can be caused due to:
1. The rise in the skin temperature is generally due to the infection from bacteria or viruses that can result in the flu, cold, or certain viral diseases. The fever can be an indication of any infection or inflammation in any part of the body.
2. The activities like exercising can also lead to an increase the body temperature. The contraction of muscles releases 20% energy and the rest 80% is converted into heat energy. The heat is then circulated to different parts of the body, causing an increase in the temperature.
3. The rise in the temperature can be measured by the thermometer. It is a device that measures body temperature either digitally or traditionally.
Thus, the cause of fever can be a defense mechanism, exercise, and infection from the pathogen.

So, what is actually produced during the light reaction? Do you know the chemical
equation?
Answer:
The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH. 5. The light-dependent reactions can be summarized as follows: 12 H2O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll yields 6 O2 + 12 NADPH + 18 ATP.
Water is oxidized, electrons are transported from water to NADP+, and ATP is generated during the light processes.
What is light reaction?The light reactions are the first step in photosynthesis. The pigment chlorophyll in the thylakoid membranes of the chloroplast absorbs the energy from sunlight during these reactions. The energy is subsequently briefly transferred to two molecules, ATP and NADPH, which are used in photosynthesis' second stage. Two electron transport networks produce ATP and NADPH. Water is used in the light processes, and oxygen is created. Because the process requires sunlight to begin, these reactions can only take place during daylight hours.the reaction is provided in the image below:

Hypothesize what the results would be if a large cell managed to divide, despite the fact that it had grown beyond an optimum size
Answer:
Hypothesize what the result would be if a large cell managed to divide, despite the fact that it had grown beyond an optimum size. The resulting cells could not sustain themselves if the plasma membrane to cell contents (SA to Volume) ratio was too small a difference.
Explanation:
It is likely that the resulting daughter cells would be smaller than normal and may not function properly, potentially leading to impaired growth or viability of the organism.
What happens when cells divide after growing beyond an optimum size?If a large cell managed to divide despite the fact that it had grown beyond an optimum size, it is likely that the resulting daughter cells would be abnormal in size or function. Cells that are larger than the normal range for their type tend to have problems with DNA synthesis and cell division. The DNA may not be accurately replicated, leading to genetic errors and abnormal gene expression. The cell division process may also be impaired, resulting in cells that are larger or smaller than normal.
The consequences of these abnormalities could be serious and potentially harmful to the organism. Abnormal cells may be unable to perform their normal functions, leading to deficiencies or malfunctions in the tissues or organs where they are located. In extreme cases, abnormal cells may become cancerous and contribute to the development of tumors. For these reasons, it is important for cells to divide when they are at an optimal size, in order to ensure that the daughter cells are healthy and functional.

DNA replication results in two separate DNA molecules. How are the DNA molecules at the end of the process related to the DNA molecule at the beginning of the process.
The DNA double helix. Helices open as hydrogen bonds disintegrate. The creation of a new, complementary strand uses the template provided by each DNA strand.
What is the regulation of DNA replication process?A new and an old chain of nucleotides is combined to form two DNA molecules as a result of DNA replication.
Because half of the chain is made up of the original DNA molecule and half is new, DNA replication is referred to be semi-conservative.
With one new and one old strand in each, replication creates two identical DNA double helices.
The production of a primer, a brief section of RNA that serves as the beginning point for the synthesis of fresh DNA, follows.
Therefore,DNA helicases unwind DNA during DNA replication at locations known as origins where synthesis will begin.

Answer:
1. Viking 1 and Viking 2 probes transmitted panoramic views of the red and rocky soils back to Earth after six years later. The Pathfinder probe sent back large amounts of data of the environment especially about climatic variations in only three months. You can tell the technology was very different between these two because of how long it took for each probe to gather data.
2. In 1965, Mariner 4 and 9 probes found geological formations (Olympus Mans). The Mariner 4 sent back the first image of Mars. The Mariner 9 found erosion marks that indicated that there was once water on Mars. In 1976, the Viking 1 and 2 probes transmitted panoramic views of the soils. From 1965 to 1976, they were able to discover more about Mars over improving the technology. When the Viking probes were launched, we discovered more than when the Mariner probes were launched. For example, we were able to uncover how red and rocky the soils were.
3. We now receive information differently thanks to wireless technology. For instance, we now have computers and phones that let us contact someone by simply pressing a button. GPS may now be used to display various places. Additionally, we can now forecast the weather. We can know the weather for every day because forecasters have access to a ton of technology. Thus, we now substitute archaic methods for digital ones.
4. Fire alarm and air conditioning systems include technologies that incorporate various communication systems that enable them to react to changes in the atmosphere or temperature. Therefore, when the atmosphere's temperature fluctuates, they are utilized.
5. Viking 1 and 2 were used to find life on Mars. Since they launched the Mainer probes, they found that there was once water on Mars which later created the Viking 1 and 2 probes for further investigation. Along with finding life on Mars, they were also created to take better photos of the planet.

What is the genetic code of the Reading strand
Answer:
DNA
Explanation:
The genetic code reads DNA sequences in groups of three base pairs, which means that a double-stranded DNA molecule can read in any of six possible reading frames--three in the forward direction and three in the reverse. A long open reading frame is likely part of a gene.
The genetic code (genome) of the reading strand is ATGACG, The DNA sequence is read in the 5′-3′ direction. Genes or other sites can be positioned upstream (towards the 5′ ends) or downstream (towards the 3′ ends) on a DNA strand.
What is genetic code?A double-stranded molecule that makes up the majority of chromosomes and holds the genetic code is DNA, sometimes referred to as deoxyribonucleic acid.
The nucleotides of DNA or RNA are arranged in the genetic code. Codons are made up of three-base groups and each one represents an amino acid (or start or stop).
Once a stop codon is reached, the codons are read in order starting with the start codon. Universal, clear-cut, and redundant describe the genetic code.
Therefore, the genetic code (genome) of the reading strand is ATGACG.
