Explanation:

Answer: 1. The right answer is amphibian.

2.  The right answer is Mollusks.

Explanation:

1. Regenerating a limb is not possible in mammals, as in most vertebrates. But in amphibians such as the salamander yes!

This amphibian does it very well, capable of making tail, eye or snout too. For a very long time, scientists have been trying to understand this secret of the salamander, or that of the zebrafish, because the answer is scientifically interesting but also, of course, because we can hope to take advantage of it to imagine one day of medical treatment for injured members. Just over a year ago, an Australian team showed the role of macrophages, cells of the immune system.

2. Mollusks (Mollusca) are a branch of Lophotrochozoans animals. They are unsegmented animals, with bilateral symmetry sometimes altered. Their body usually consists of a head, a visceral mass, and a foot. The visceral mass is covered in whole or in part by a mantle, which secretes a calcareous shell. The nervous system includes a double periesophageal collar. The general cavity is more or less reduced to pericardium and nephridia.

Photosynthesis and cellular respiration are, in a way, opposite reactions.

While photosynthesis takes the light energy and water and converts carbon dioxide into glucose, cellular respiration takes the glucose to produce chemical energy and it results in carbon dioxide and water.

This means that both reactions involve glucose, carbon dioxide, and also water, so this would be the correct answer (A).

The answer to this question is B. enzyme have particular pH's at which they function best, since we can see both enzymes at different pH values, have different reactions rates: considering enzyme 1, the highest reaction rate is in pH 10, and considering the enzyme 2, the highest reaction rate is in pH 9.

Kuru is a Transmissible spongiform encephalopathy which was formerly common among the Fore people of Papua New Guinea. This disease is caused by a prion, i.e., a protein that can trigger other proteins in the brain to fold abnormally. The abnormally folded proteins in the brain cause neurodegeneration which ultimately lead to death. The main symptom of the Kuru disease is the loss of coordination and control over the muscle movements. The transmission of Kuru was because of a ritual in which Fore people consumed body parts of their family members just after their death. The Fore people stopped to eat human meat in the early 1960s, causing the kuru epidemic to decline dramatically. It is not certainly known if the last kuru victim died in 2005 or 2009.

Answer:

Patagonia is the southern psrt of south america.

Freshwater wetlands are ecosystem affected by inundation (permanently or temporary). The three major types are swamps (uncultivated low-lying ground where water collects), marshes (low-lying and waterlogged land, flooded in wet seasons or at high tide) and bogs (wet muddy ground that's too soft to support a heavy body).

The phrase dune erosion by ocean water along a shoreline best describes a density-independent limiting factor that can affect ecosystem stability (Option B).

A density-independent limiting factor can be defined as any factor in a given ecosystem that may alter the homeostasis of the population that lives in a given geographic area.

These factors (density-independent limiting factors) are generally abiotic factors such as hurricanes, extreme temperature conditions, the presence of contaminants in the air that hamper life in a given area, etc.

Conversely, density-dependent limiting factors are biotic factors such as competitive species that alter the development of another population.

Therefore, with this data, we can see that a density-independent limiting factor is any abiotic condition that may alter the life of a population in a give geographic area and thus alter the homeostasis of the whole ecosystem.

Explanation:

It is true that, Despite the fact that the complexity of animal nervous systems varies, their nerve cells are still remarkably similar.

Nearly all multicellular animals have nerve systems, but their complexity varies greatly. Sponge and the tiny blob-like placozoan and mesozoan organisms are the only multicellular animals without a nervous system. A diffuse nerve net makes up the nervous systems of ctenophores (comb jellies) and cnidarians (such as anemones, hydras, corals, and jellyfish). With the exception of echinoderms and a few worm species, all other animals have a nervous system that includes a brain, a central cord (or two parallel cords), and nerves that radiate from the brain and central cord.

The nervous system's most fundamental roles are to direct an organism's movement and to influence its surroundings (such as through pheromones). Signals are sent from one cell to another or from one part of the body to another to accomplish this. Signals that travel to muscle cells trigger the activation of muscles and signals that travel to endocrine cells triggers the release of hormones into the bloodstream or other internal fluids are the sources of the output that the nervous system produces.

To be considered as fit for evolution processes, a species must be able to adapt in its environment and with capacity to reproduce sucessfully. Ambrosia, for example, is an invasive species. It has the abillty to promote accelerated evolution due to its adaptibility to its environment. Zea mays is an excellent species for genetic analysis. Quercus also has evolutionary potential because of its physiological characteristics.

Answer:Key Points. Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.

Explanation:

The vascular plants have several specialized reprodutive organs, which one responsible for one stage of the process of reproduction. The flowers are reprodutive organs, as well as fruits and cones, however they function in reproduction is distinct. The flowers is the most complex reproductive organ, since it is composed by for different structures (carpels, staments, petals and sepals), the cones are where the seeds are produced in the female plants during sexual reproduction after being fertilised by male gametes (pollen), and the fruits are the result following the pollination that are important to continuity of plants generations. Therefore, the alternative D (all of them are correct) is the answer for that question.

Hi. We just had a session with this same question is there any doubt left?

Answer:

from the pelvis or to more distant parts of the abdomen.

Explanation:

Body systems must work together. If one system will be damaged or fails, the other systems will be affected. If the digestive system will be fail, digestion will fails. Water will not be absorb that will lead to the circulatory system to have difficulty in the consistency of blood. If there is a presence of digestive disease, there will be an interference in the digestion as well. Other organ functions will be affected, too. Several effects will be seen such as dehydration, poor absorption of nutrients, blocked blood flow, etc. If the digestive shuts down due to damage of muscles or nerves, it may cause nausea, vomiting, lack of appetite and malnutrition. The nervous and circulatory systems work with the digestive system and these systems are greatly affected if it will not work properly.

The respiratory system is affected if the digestive system fails. These two systems work together to provide power to the entire body system. If digestion fail due to overeating, it can cause abdominal bloating. Bloating can lead to shortness of breath.

The reason why these cells can develop too many tasks at once, beyond having the specific genes expressed, is that they can constantly produce usable forms of energy in form of ATP by using glucose in cellular respiration. So the correct answer to this question is the final one.
