Answer: I would say it's because there is so much about the brain that we don't know about yet, it's harder for us to understand certain illnesses and dysfunctions because of the sheer complexity of the organ and the role it plays in our own existence. It's easier to understand an organ such as the pancreas because while both fragile and complex, it is not nearly as mysterious as the human brain and doesn't have even nearly the same range of function.

Answer:

False. The purpose of the Darwin Finch lab was to establish that the relationship between food sources and beak shape was food availability.

Explanation:

Finches speciation was due to geographical isolation on islands and the differences in their picks were an evolutive adaptation that reflected feeding habits. Their speciation depended on or was the result of their adaptation to the island and its characteristics. The finches´ beaks evolved according to food availability. Large beaks are better for islands with larger seeds, while pointed beaks are better for getting insects out of trees.

Answer: The traits of those who died before reproducing deemed "undisireable" (like a tale,scales,wings etc.) would have died out as they would not have had the opportunity to pass on these genes. Those of the same species who survived due to a lack of the "undisireable" trait would have the opportunity to reproduce and pass on the complete lack of the trait itself or a smaller version of the trait. This is what enables different species to adapt to live in different enviorments,you can observe this in different species that share a common ancestor.

Explanation: It's kind of in the answer

Habitat is like where the animal lives, and niche is its position in the community, like predator

Answer:

Proteins range in molecular weight from 1000 to more than 1 million daltons (Da), but the folded size of a globular protein is not necessary correlated to its molecular weight. Proteins composed of about 250 amino acids or less often have a simple, compact globular shape. Larger globular proteins are usually made up of two or more recognizable and distinct structures, termed domains or modules. These are compact, folded protein structures that are usually stable by themselves in aqueous solution. Typical domain structures consist of hydrophobic cores with hydrophilic surfaces. Individual domains often possess unique functional behaviors and often perform unique functions within the larger protein in which they are found.

Answer:

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs , "light", and sunthesis, "putting together". In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.

Schematic of photosynthesis in plants. The carbohydrates produced are stored in or used by the plant.

Overall equation for the type of photosynthesis that occurs in plants

Composite image showing the global distribution of photosynthesis, including both oceanic phytoplankton and terrestrial vegetation. Dark red and blue-green indicate regions of high photosynthetic activity in the ocean and on land, respectively.

Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centres that contain green chlorophyll pigments. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas. The hydrogen freed by the splitting of water is used in the creation of two further compounds that serve as short-term stores of energy, enabling its transfer to drive other reactions: these compounds are reduced nicotinamide adenine dinucleotide phosphate (NADPH) and adenosine triphosphate (ATP), the "energy currency" of cells.

In plants, algae and cyanobacteria, long-term energy storage in the form of sugars is produced by a subsequent sequence of light-independent reactions called the Calvin cycle; some bacteria use different mechanisms, such as the reverse Krebs cycle, to achieve the same end. In the Calvin cycle, atmospheric carbon dioxide is incorporated into already existing organic carbon compounds, such as ribulose bisphosphate (RuBP). Using the ATP and NADPH produced by the light-dependent reactions, the resulting compounds are then reduced and removed to form further carbohydrates, such as glucose.

The first photosynthetic organisms probably evolved early in the evolutionary history of life and most likely used reducing agents such as hydrogen or hydrogen sulfide, rather than water, as sources of electrons. Cyanobacteria appeared later; the excess oxygen they produced contributed directly to the oxygenation of the Earth, which rendered the evolution of complex life possible. Today, the average rate of energy capture by photosynthesis globally is approximately 130 terawatts, which is about eight times the current power consumption of human civilization. Photosynthetic organisms also convert around 100–115 billion tons (91–104 petagrams) of carbon into biomass per year.

The fact that plants receive some energy from light—in addition to air, soil, and water—was discovered in 1779 by Jan Ingenhousz.

Answer:

It is often assumed that the moon is a perfect sphere, which it is not. The side of the moon facing earth is more dense than the side facing away. Therefore, it takes energy for the moon to rotate its earth-facing side away from the earth. Such energy is not currently available, so the same side always faces earth, caught in earth’s gravity.

Explanation:

Hope this helps you a lot my boo!

Answer:

The moon keeps the same face pointing towards the Earth because its rate of spin is tidally locked so that it is synchronized with its rate of revolution (the time needed to complete one orbit). In other words, the moon rotates exactly once every time it circles the Earth

Explanation:

Iron deficiency can lead to anemia.

Answer:

The correct answer is - Both move with constant speed.

Explanation:

If an object moves in a particular way that it covers the same distance at the same times the speed considered as constant suppose if two objects a and b both travel 10 m and 20 m respectively and the time they take in travel are 2 and 4 seconds respectively than we can say they both have a constant speed.

The relation between the variables x,t, and v is

x=v.t

If V is constant which is the speed we get a straight line x-t in the graph.

By the given information we can say that both objects A and B are traveling at a constant speed.

The sentence that best describes the two cell models is they have the same volume, but model B has more surface area. The correct option is C.

The surface area of any solid object is the total area covered by it. Surface area is calculated by adding all the areas, the top, base, and lateral.

Model A and B have the same volume but as a model, B is divided into four parts, it increased its surface area.

Thus, the correct option is C. They have the same volume, but model B has more surface area.

The answer is MITOCHONDRION

Explanation:

All living organisms need energy at the cellular level to carry out their cellular activities. This energy is obtained by eating food. The energy in food is stored in the bonds of the sugar molecule that is contained in it.

However, via a process called CELLULAR RESPIRATION, the stored energy in food is broken down and used to synthesize a form of energy usable by the cell called ATP. This important process occurs in the organelle called MITOCHONDRION.

Explanation:

Crystallization generates solids by organizing atoms or molecules into a crystal structure. Crystals develop via solution precipitation, freezing, or rarely gas deposition. Therefore, option (B) is correct.

The formation of a solid involves a process known as crystallization, in which the constituent atoms or molecules become highly ordered into a structure known as a crystal. Crystals can form in a number of different methods, including by precipitating from a solution, freezing, or, although this occurs less frequently, deposition directly from a gas.

There are two primary stages involved in the crystallization process. The first step is called nucleation, and it refers to the formation of a crystalline phase from either a liquid that has been supercooled or a solvent that is supersaturated. Crystal growth is the term given to the second stage of the process, which involves an increase in the size of the particles involved and ultimately results in a crystallized form.

Therefore, when a solution is evaporated, some of the solvent evaporates, leaving behind a saturated solution. Cooling the saturated solution forms crystals. Filtration removes crystals.

Answer: Natural selection allows the survival of organisms with beneficial traits.

Explanation:

Natural selection can be defined as the differential survival and reproduction of the members of the population that have beneficial phenotypic traits to survive in unfavorable environment. These organisms reproduce and pass on their traits to the next generation such species does not extinct in future.

The natural selection allows evolution of species with the adaptation of new traits so as to allow the survival of the organism.

The correct answer is D. All of these

Explanation:

Scientific predictions are based on previously recorded information, which includes observations, data gathered with precise instruments, mathematical models, measurements, among others. This allows scientists to understand phenomena objectively by using the scientific method and to make accurate predictions.

Despite this, scientific predictions might slightly, or completely change over time. This is because new tools or methods might provide scientists with new contradictory evidence about the phenomenon. Moreover, any type of evidence gathered as part of the scientific method is valid to evaluate a previous prediction such as observations, data, models, measurements, among others.
