A component of the cell theory is that all living things are composed of one or more cells. A component of the cell theory is that the cell is the basic unit of life.A component of the cell theory is that all new cells arise from existing cells.27. A certain type of toad resembles tree bark with its brown color and rough skin. A certain type of frog, has a bright yellow-green color with red toes and smooth skin. How does the appearance of each organism most likely help them survive?
Answer:
Frogs go brrrrr
Explanation:
If a brown toad is in a forest then it will be harder to spot. If a bright yellow-green colored frog were in the same forest, it would be much easier to spot. So their appearence helps them survive by being harder to spot and allowing them to live and avoid preadators.

Two colleagues that share the same office are exposed to the flu virus one week in January. Janet just recovered from the same flu virus two weeks earlier, while Mark has not been sick yet this winter. Which person do you expect would be more likely to become sick with this flu virus and why?
Janet: since she already had the flu, her immune system is weaker than Marks.
Janet: she will most likely get the flu again, and a more severe case of it.
Mark: he has not acquired any active immunity to the flu, and Janet has.
Mark: he has only passive immunity to the flu which will not benefit him in this case.
I believe Mark is more likely to get sick with the flu virus because Janet has acquired a slight immunity because she was infected with it while Mark has not been infected with the virus
It refers to the group of ecosystem sharing the same climate
Answer:
The correct answer is - Biome.
Explanation:
A biome is large area with a particular climate in this region of the earth and typical animals found in the particular area. Biom have different group of ecosystem present in it but live together in a particlular or same climate.
All plants and animals found in every biome has advantage as biome have specific traits like temerature, precipitation, sunlight or humididty and mnymore that help in surviving. For instance, polar bear will live only low humidity and low temperature.

A medical student is studying how the volume of blood in the circulatory system affects blood pressure. He measures the blood volume and pressure of two classmates, a man and a woman. He finds that the man has a higher blood volume but a lower blood pressure than the woman. He concludes that a person with low blood volume would tend to have high blood pressure. What additional factors should the student consider that would most likely affect blood pressure? (1 point)

The mitochondria has been described as the engine of the cell. Why is this a fitting nickname? How is this organelle involved in the process of cellular respiration?
Describe the process of photosynthesis in plants. Why is this process important to animals and humans?
How are the processes of cellular respiration, photosynthesis and carbon cycle related to each other?
Explain how one of the processes discussed in this module (photosynthesis, cellular respiration or the carbon cycle) apply to both the Law of Conservation of Matter and Law of Conservation of Energy.
Answer:
1.Mitochondria is considered as the power house of the cell as it helps in producing large amount of energy in the form of ATP (adenosine triphosphate) that is used in driving various cellular activities.
2.Through a process called photosynthesis, plants use energy in sunlight to turn a gas called carbon dioxide and water into sugar. Plants then use this sugar to grow. At the same time, plants produce a gas called oxygen as a waste product, which is lucky for us and other animals because we need oxygen to breathe!
3.Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways 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.
4.Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2). How does photosynthesis demonstrate the law of conservation? ... The AMOUNT of carbon-dioxide atoms released by respiration are EXACTLY EQUAL to the atoms of these materials contained in the oxygen and carbon converted.The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law because the same carbon atoms are being recycled through the carbon cycle. ... Carbon is used for energy, and some is stored for growth.

Explanation:
Distinguish the types of forgetting: anterograde amnesia, retrograde amnesia, encoding failure, retrieval failure, and interference (both retroactive and proactive).
Answer:
Anterograde amnesia is the inability to create new memories after the onset of amnesia, while memories from before the event remain intact. Brain regions related to this condition include the medial temporal lobe, medial diencephalon, and hippocampus. Anterograde amnesia can be caused by the effects of long-term alcoholism, severe malnutrition, stroke, head trauma, surgery, Wernicke-Korsakoff syndrome, cerebrovascular events, anoxia, or other trauma. Retrograde amnesia is the inability to recall memories made before the onset of amnesia. Retrograde amnesia is usually caused by head trauma or brain damage to parts of the brain other than the hippocampus (which is involved with the encoding process of new memories). Brain damage causing retrograde amnesia can be as varied as a cerebrovascular accident, stroke, tumor, hypoxia, encephalitis, or chronic alcoholism. The there is encoding failure. Encoding is the process of converting sensory input into a form able to be processed and stored in the memory. However, this process can be impacted by a number of factors, and how well information is encoded affects how well it is able to be recalled later. On the other hand, retrieval failure is the failure to recall information in the absence of memory cues. Proactive interference occurs when old memories hinder the ability to make new memories. In this type of interference, old information inhibits the ability to remember new information, such as when outdated scientific facts interfere with the ability to remember updated facts. This often occurs when memories are learned in similar contexts, or regarding similar things. It’s when we have preconceived notions about situations and events, and apply them to current situations and events.Retroactive interference occurs when old memories are changed by new ones, sometimes so much that the original memory is forgotten. This is when newly learned information interferes with and impedes the recall of previously learned information. The ability to recall previously learned information is greatly reduced if that information is not utilized, and there is substantial new information being presented. This often occurs when hearing recent news figures, then trying to remember earlier facts and figures.
Explanation:
Lisa and Vinay are looking under a microscope at animal cells. They see an organelle
that they think is the endoplasmic reticulum. Which statement would support their
idea?
•the organelle contains DNA
•Othey observed ribosomes on the structure
Answer:
The correct answer is - they observed ribosomes on the structure.
Explanation:
The endoplasmic reticulum is the cellular organ eukaryotic organisms, that is tubular in shape and present in the cytoplasm that plays role in protein folding and part of the transport system of the cell. It has two subunits smooth endoplasmic reticulum and rough endoplasmic reticulum.
Rough endoplasmic reticulum has ribosome molecules present on the surface of the structure that is sending the protein to ER where folding of the protein and transport of the protein.

Describe how transposable elements create mutations within an organism and how transposable elements facilitate chromosomal rearrangements.
Answer:
Transposable elements are discrete segments of DNA that can be excised and reintegrated to another site in the genome, these can inactivate the gene in which they reside, cause chromosome breaks, and / or transpose to a new location within the genome.
Explanation:
Transposable elements are fragments of DNA that have the ability to jump from one part of the genome to another. While most of the DNA is always in the same place surrounded by the same neighboring pieces of DNA, mobile elements move from one place to another causing many changes or mutations. When a transposon moves through the genome, it can insert into a vital gene, disrupting its function, or into a location near vital genes, causing erroneous activation or inactivation.On the other hand, there can be chromosomal rearrangements due to transposons of the same family with complementary sequences that are separated in the genome and that by sequence homology match. This can lead to ectopic recombination. Large-scale rearrangements induced by mobile elements are considered a particular class of recombination events that influence genomic plasticity.

What is the difference between domestication and natural selection?
Answer:
By definition, natural selection is the survival of the fittest.
Explanation:
Natural selection, in itself, is not a generator or creator of evolutionary novelties, but it only exposes certain variants.
Variants do not arise under the induction of the environment, but randomly, by chance, by a combination of genetic material, something that already exists in the genetic fund of a species.
Domestication is a term used for the process by which various biological organisms adapt to survive in society or through the work of human beings.
