Most fresh water fish are hypertonic, meaning their body cells contain more salt than the surrounding water. Since osmosis should push water into their cells, why don't they explode? They don'Ât drink any water because they get so much from osmosis. They have adapted to live with high osmotic pressure. They urinate a lot, so the water does not build up. Their cells have adapted to absorb salt. All of the above
Answer:
They urinate a lot, so the water does not build up.
Explanation:
Freshwater fishes are fishes that live in freshwater habitat i.e. little or no salt. This means that the fishes are hypertonic (have more salt) to their external environment. Due to their hypertonicity, freshwater fishes tend to take in more water via osmosis.
Freshwater fishes, however, do not explode despite this phenomenon because they pass out the excess water via urine waste. Freshwater fishes urinate a lot, hence, the absorbed water does not build up in their bodies.

Which of the following are NOT roles that zygomycota play in our ecosystem? Select all that apply.
They can have beneficial relationships with plants.
They are used in baking bread.
They are used in making beer or wine.
They are great decomposers of plants, soil, and dung.
They are used to control pests.
Functions that Zygomycota does in our ecosystem, have advantageous connections with plants, are excellent decomposers of plants, soil, and manure, and are employed to manage pests, hence options B and C are correct.
What are the roles that Zygomycota?They often dwell in the soil and eat decomposing plant waste close to plants. They play a significant part in the carbon cycle by decomposing manure, plant debris, and soil.
A group of fungi known as the zygomycetes is capable of causing disseminated, locally invasive, and cutaneous infections.
Rhizopus spp., Rhizomucor spp., Absidia spp., Apophysomyces spp., Cunninghamella spp., and Mucor spp. are all members of this class.
Therefore, the group of fungi known as Zygomycota may be the most ecologically diversified, hence options B and C are correct.

Porque los bioelementos y las biomolegulas son importantes para todos los organismos
Explanation:
Bioelementos
De los más de 100 elementos encontrados en la Tabla periódica, la materia viva está
constituida por unos 70 elementos y solo alrededor de 21, son esenciales para el desarrollo y
conservación de la vida. Estos elementos se llaman bioelementos o elementos biogénicos.
Bioelementos Primarios
Están formados por: C, H, O, N, P y S, los cuales constituyen alrededor
del 96.2% de la materia viva en base seca. Son los componentes
fundamentales de las biomoléculas. Son iimprescindibles para formar:
carbohidratos, lípidos, proteínas y ácidos nucleicos.
Clasificación de
los bioelementos
Bioelementos Secundarios
Grupo comprendido por los iones: Na+
, K+
, Ca2+, Mg2+, Cl-
. Estos
elementos aunque se encuentran en menor proporción que los
primarios, también son indispensables para los seres vivos. En medio
acuoso (solvente presente en células tejidos y órganos), siempre se
encuentran ionizados.
Oligoelementos
Son aquellos bioelementos que se encuentran en los seres vivos en un
porcentaje menor del 0.1%. Algunos, los indispensables, se encuentran
en todos los seres vivos, mientras que otros, variables, solamente los
necesitan algunos organismos. En este grupo se encuentran: Fe, Cu,
Zn, Mn, I, Ni y Co (que aparecen en la mayoría de los organismos) y Si,
F, Cr, Li, B, Mo y Al (sólo están presentes en grupos concretos).
Constituyen menos del 0.1% y son esenciales para desempeñar

14. Brainstorm and write at least 3 potential challenges or important points to consider when conducting the described
data collection.
When conducting an experiment, there are different aspects to consider, such as the question that drives to the reseach, the hypothesis, theoretical framework, variables involved -independent, dependent, and controll-, methodology, study groups, data analisys, among others.
In the exposed example, Pincky is lacking theoretical framework, defining which are the study groups, methodology to collect data, and a description of data analysis.
---------------------
The scientific method is a research method that consists of systematic observations, measures, experimentation, analysis, and verification of a hypothesis. It is based on two aspects: reproducibility, which is the capability of reproducing the experiment in any other place by any researcher, and refutability, which is the susceptibility to be refused.
When conducting an experiment, you need to consider,
• Definition and problem statement. The question for which there is not an answer yet.
• Hypothesis formulation. A hypothesis is a scientific conjecture, not verified, that requires corroboration.
• Data collection and analysis. This step involves testing the observations.
• Results
• Verification of hypothesis. This step involves the deriving of the working hypothesis.
• Discussion and Conclusion.
Previous knowledge about the study object is always required for a better understandig. A question the investigator wants to answer. The main goal of the study, which is basically what the investigator wants to find out. The researcher makes a hypothesis to predict what is going to happen. The experiment is to be performed to answer the question. The conclusions through which the hypothesis might be rejected or accepted.
--------------
So in this experiment there must be,
Theoretical framework, such as information about the species, life stage at which they begin chirping, about external factors that might affect it or benefit it, and etcetera.
The goal: To know how temperature affects cricket´s chirping
Hypothesis: Crickets chirp less frequently under cold temperature than under warm temperature.
Variables: Temperature → Independent
Chirp frequency → Dependent
Water and food supply, light exposure, refuge → Controlled
Study groups: group of crickets exposed to a warmer temperature
group of crickets exposed to a colder temperature
Methodology: Individuals analyzed should be in the same development stage, or at least be sexually mature. Two groups of 10 individuals each should be placed under the same conditions, excepting for temperature. One of the groups should be exposed to warmer temperatures and the other one to lower temperatures. Chirps should be recorded for a week.
Data analysis: Using the chirps records, the frequency can be measured for each group. Results should be compared using different statistical analyses.
Results: Results should be clearly exposed, using texts, charts, and graphs.
Discussion and Conclusion: Hypothesis acceptance or rejection. Discussion about the expected results against the observed ones.
