A food chain represents one possible pathway that energy and matter can take in an ecosystem, whereas food web contains multiple, interconnected food chains and describes how energy and matter moves through an entire ecosystem. Thus, the correct option is A.
A food chain is a component of the food web. It represents a unidirectional flow of energy and matter, that is one producer will have only one primary consumer which in turn will have only one secondary consumer, and then a single predator.
However, in the food web, the producer will have several primary consumers which in turn will have many secondary consumers and predators. A single consumer can consume multiple components from the food web.
Thus, the correct option is A.

More than 20 species of Hawaiian honeycreepers are descended from a goldfinch-like ancestor that arrived on one of the islands about 5 million years
ago from Asia or North America. The birds of the various species are similar in body size and shape, but differ in color and boak shape. How could so
many species have evolved from a single ancestral species?
Fill in the missing words.
natural selection
founder effect
geographically isolated
species
evolution
The ancestral finch founded a new population on one of the Hawaiian Islands. Due to the
allele frequencies of the first
small population on one of the islands chuld have differed from their continental goldfinch-like ancestors. The process of
resulted in adaptation and
of the island population into a new
over time. Some of the birds crossed to some of the other islands where they were
and
evolved into more species occupying different niches.

Answer:
Several studies have found strikingly different allele frequencies between continents. This has been mainly interpreted as being due to local adaptation. ... Namely, allelic surfing during a population range expansion may increase the frequency of alleles in newly colonised areas
¿Cuál de los siguientes enunciados NO forma parte de la teoría celular propuesta por Schleiden y Schwann, y con aportes de Virchow? * E) Toda célula deriva de otra preexistente D) Todos los seres vivos están formados por células. C) La célula es la unidad de evolución de los seres vivos. A) La célula es la unidad de estructura de los seres vivos. B) La célula es la unidad funcional de los seres vivos.
Answer:
C) La célula es la unidad de evolución de los seres vivos.
Explanation:
La teoría celular fue formulada por Schleiden y Schwann en 1837 a partir de observaciones propias y de información citológica relacionada con la estructura y la función de las células obtenida muchos años anteriores a ellos, especialmente a partir de los aportes de 1-Anton Van Leewenhoek, quien identificó microrganismos vivos mediante sus observaciones con un microscopio, y 2-Robert Hooke, quien observó celdas (de allí el nombre de células) también bajo el microscopio. Schleiden y Schwann postularon que la célula debería ser la unidad estructural y funcional en los seres vivos, la cual debería ser capaz de mantener de modo independiente el estado vital. Posteriormente, en 1855, Virchow aportó una conclusión fundamental: todas las célula derivan de la replicación (división) de células preexistentes. Los virus se consideran una excepción a la teoría celular porque ellos son considerados organismos vivos (aunque esta consideración está sujeta a debate), los cuales poseen un nivel estructural y de organización menor al nivel de una célula. Respecto a este punto, cabe aclarar que los virus son parásitos intracelulares los cuales derivan (descienden evolutivamente) de organismos celulares y por lo tanto es posible asumir a sus orígenes como subproductos de los genomas de las células (es decir, de organismos celulares).

Research that seeks to understand the source of water pollution for given body of what is an example of applied science
Answer:
True
Explanation:
Research that seeks to understand the source of water pollution for given body of what is indeed an example of applied science.
Applied science is a branch of science that deals with the application of scientific knowledge to solve real-life problems. This is as opposed to natural science which deals mainly with the physical world and is largely theoretical. When the theoretical knowledge obtained from natural science is put to real use to solve existing problems, it is termed applied science.

E. vacuole
HELP!
i believe the answer is c, cell wall^^
Cell wall supporting part of the plant cell. So, the correct option is C.
What is Cell wall?A cell wall is defined as the structural layer surrounding certain types of cells present outside the cell membrane which can be rigid, flexible and sometimes rigid. The cell wall provides both structural support and protection to the cell which serves as a filtering mechanism.
Cell wall present only in plants and some fungi, bacteria and algae. The plant cell wall is arranged in 3 layers which are composed of carbohydrates, such as pectin, cellulose, hemicellulose and other small amounts of minerals, which form a network with structural proteins to form the cell wall.
Thus, Cell wall supporting part of the plant cell. So, the correct option is C.

Which of the following do we get from biodiversity?
Explanation:
Utilitarian values include the many basic needs humans obtain from biodiversity such as food, fuel, shelter, and medicine. Further, ecosystems provide crucial services such as pollination, seed dispersal, climate regulation, water purification, nutrient cycling, and control of agricultural pests.
Biodiversity supports human and societal needs, including food and nutrition security, energy, development of medicines and pharmaceuticals and freshwater, which together underpin good health. It also supports economic opportunities, and leisure activities that contribute to overall wellbeing.

Which of the following changes are linked to an increase in ocean water temperature?
Answer A: An increase in metabolism in marine species and a decrease in dissolved oxygen in ocean water
Answer B: A decrease in metabolism in marine species and a decrease in dissolved oxygen in ocean water
Answer C: An increase in metabolism in marine species and an increase in dissolved oxygen in ocean water
Answer D: A decrease in metabolism in marine species and an increase in dissolved oxygen in ocean water
The changes that are linked to an increase in ocean water temperature are an increase in metabolism and a decrease in dissolved oxygen in ocean water.
What do you mean by Dissolve oxygen?Dissolve oxygen may be defined as a relative measure of the amount of oxygen that is dissolved in a given medium.
It is universally accepted that a lack of oxygen leads to a rise in temperature. The process of metabolism internally requires energy but on completion of it, the temperature may get slightly increased in the surroundings.
Therefore, the changes that are linked to an increase in ocean water temperature are an increase in metabolism and a decrease in dissolved oxygen in ocean water. So, the correct option is A.

Students filled two beakers with 500 mL of water each. They placed three drops of live algae culture into each of the beakers, then used a dissolved oxygen sensor to measure the oxygen content of the water in each beaker. The students then stirred 5 mL of nitrogen-rich fertilizer into one of the beakers, and labeled the beaker A. Nothing was added to the second beaker, which the students labeled B. Both beakers were placed under a high-intensity light over a weekend. On Monday, the students measured the amount of oxygen in the water of each of the beakers. Which aspect of the watershed were these students trying to model?
A. The effect of fertilizer-contaminated surface water flowing as runoff into a waterway
B. How stagnant or non-flowing water can result in providing a habitat for living organisms such as algae
