a que distancia se encuentra una gaviota respecto del nivel del mar?
Answer:
Para determinar la distancia a la que se encuentra una gaviota respecto del nivel del mar, es necesario medir la altura a la que se encuentra volando. Así, dado que el nivel del mar tiene una altura considerada como de 0 metros, si la gaviota está volando a unos 500 metros de altura, por ejemplo, esa será su distancia respecto del nivel del mar.

Which of the following lists correctly presents levels of organization from most complex to simplest?
O biosphere, community, organism, organ system
O cell, organelle, atom, molecule
O macromolecule, population, community, ecosystem
Answer:
O macromolecule, population, community, ecosystem
Explanation:
Macromolecules are very large molecules composed of atoms, such as complex carbohydrates, fats and proteins (for example, fats are macromolecules mainly composed of C, H, and O atoms). Macromolecules in turn associate to form cellular structures (eg. organelles, cytoskeleton, etc), which subsequently combine to form cells. Individuals are made up of one or more cells (i.e., unicellular and multicellular organisms, respectively). In the next level, populations are groups of individuals of the same species that live within a given area; whereas communities are groups of populations that live in a given area and interact with one another. Finally, an ecosystem can be defined as a group of populations (i.e., a community) and the abiotic factors (i.e., nonliving parts) of their environment that support them (e.g., water, light, radiation, temperature, etc).

If you wanted to study large, migratory grazing animals like wildebeest, which biome would you chose to visit?
Answer: Savanna
Explanation:
The Savanna is a biome located in Africa and characterized by a lot of grass and dispersed trees. The climatic conditions are warm all year round and the summers are wet.
The presence of so much vegetation makes it an ideal biome for large herbivores like elephants, giraffes and wildebeests. As a result of so many herbivores being there, there are lots of carnivores as well such as lions and cheetahs.

Which phase of the cell cycle is the least common process of mitosis and what could be the reason?
Answer:
In anaphase, the shortest stage of mitosis, the sister chromatids break apart, and the chromosomes begin moving to opposite ends of the cell. By the end of anaphase, the 2 halves of the cell have an equivalent collection of chromosomes. In telophase, 2 daughter nuclei form. The nuclear envelope beings to reappear.
Darwin presented a hypothesis about how evolution takes place. Now this hypothesis has become a theory. What caused the idea to become a theory? A. Darwin shared his ideas with others, and many scientists have performed experiments that support this idea. B. Darwin is well respected, and scientists honor his work by referring to his idea as a theory. C. Darwin performed an experiment that supported his hypothesis. D. Darwin convinced everyone around him that it was a good idea.
Answer:
C. Darwin performed an experiment that supported his hypothesis.
Explanation:
Darwin believed that his experiment, which was comparing the finch's beaks from Galapagos Archipelago, in which there was variation between the size and shape of beaks, as the basis in which he believed evolution was correct. However, variation does not mean evolution, and evolution, in which it calls for a chain of events to create beneficial traits successively, is nigh impossible to occur in the real world. Again, that is not to say that there is no such thing as variation, in which there is, in which people or animal groups adapt to their natural habitat. However, to state that adaptation is proof that a species becomes another is to go out on a limb, and current failures of "new species" (in that it originates from today's day and age, rather then discovered) to emerge is proof of such.

Answer:
Chitin.
Explanation:
The structure that is not a component of wall of sponges is Chitin. Their body comprise of calcareous or siliceous spicules or protein spongin fibres. Choanocytes are the distinctive cells located in the interior body walls of sponges. Sponges are similar to other animals in many characteristics such as they are multicellular, heterotrophic, lack cell walls and produce sperm cells in order to produce offspring sexually and also different from animals due to lack of tissues and organs.

What is a controlled variable?
Answer: A controlled variable or constant variable is a variable that does not change during an experiment.
Explanation:
A controlled variable or constant variable is one which the researcher holds constant (controls) during an experiment. It is also known as a constant variable or simply as a control.The control variable is not part of an experiment itself it is neither the independent nor dependent variable but it is important because it can have an effect on the results gotten.

A microbiologist is conducting a research project on chemolithoautotrophs. This means that the investigator is examining certain aspects of a bacterium that is a purple nonsulfur bacteria which depends on light. uses light as its energy source and carbon for organic compounds. can oxidize inorganic molecules such as ammonia and sulfur for energy. can use the energy from sunlight to build organic molecules from carbon dioxide. obtains carbon from organic molecules.
Answer:
uses light as its energy source and carbon for organic compounds.
Explanation:
The purple non-sulfur bacteria which depends on light produces organic food just like plants through the process of photosynthesis. The purple non-sulfur bacteria uses carbondioxide and water with sunlight produces oxygen and glucose which is an organic compound. So that's why purple non-sulfur bacteria is also known as phototrophic means organism that produces their own food through photosynthesis.
Tell me how bacteria make their energy and other chemical products.

A therapist examining the roles, rules, expectations, power hierarchy, and boundaries within a
family is focused on which of the following areas of assessment?
Answer:
This question lacks options, options are:
A) family affect
B) family strengths
C) family process
D) family organization.
The correct answer is D.
Explanation:
The family is a system that is constituted by a network of relationships and made up of subsystems where each member evolves and develops through different stages, undergoing adaptation changes where the norms, rules, limits and hierarchies that work are essential in the family environment. Family therapy is understood to be that modality of therapy focused on the family as an object of intervention, its objective is to achieve the change of negative interaction patterns between the members of a family. Family organization refers to the interaction between all its members who are part of the same institution united by emotional ties. The organization describes the totality of the existing relationships between the people that make up the system, then the family organization refers to the functional demands, distribution of rules and transactional guidelines that constitute the ways of interacting of each individual within the family. The transactional guidelines are those that normalize the behavior of each member and are preserved by two systems of coercion; the first established by universal norms in turn existing roles and hierarchies; the second is the characteristic of each member involving its interests and expectations.

Every day we make choices that can potentially affect our environment. For example, we may toss a plastic drink bottle into the nearby trash because it’s more convenient than walking all the way to the recycling bin. Think about three choices you made this week that could have affected the environment. Did your choices have a positive or a negative effect on the environment? Explain your reasoning.
The three choices that could have affected the environment are as follows:
Utilization of plastic to make it easy for carrying objects.Plants trees in order to build a green environment. Overdependency on vehicles rather bicycles and pedestrians. What is Environment?The environment may be defined as anything which is present in the surroundings of living organisms. This environment basically has two types of factors biotic and abiotic factors.
In the above three choices, building a green environment has a positive effect on the environment. It may also affect living organisms positively. While the rest of the two may stimulate a negative impact on the environment by increasing the levels of carbon dioxide by liberating emission and non-biodegradable plastics.
Therefore, the three choices that could have affected the environment are well mentioned above.
