Many people who own pet fish put a pondweed called Elodea canadensis in their
fish tanks. This species of pondweed produces an extremely high amount of oxygen.
If many fish were placed in a tank without this species of pondweed or a filter, what
would likely happen?
Answers
Answer:
In the scenario given above, Elodea Canadensis which produces extremely high amount of oxygen is used in raising fishes placed in a tank. This oxygen is needed for easier living in the tank. In a situation whereby the Elondea Canadensis is not present in the tank, the fish would struggle to leave comfortably in the tank. with time, the water will become clouded with carbon-dioxide. This would lead to the fish dying due to lack of oxygen.

Floor of the forest is mainly consists of shed vegetative parts of shrubs and trees, such as leaves, branches, bark, and stems etc. These parts exists in various stages of decomposition present above the soil.
Not all traits are determined solely by genes. Many traits have been found to exhibit phenotypic plasticity, which
occurs when individuals with the same genotype exhibit different phenotypes in different environments. Which of the
following is an exampleof phenotypic plasticity?
Well-maintained hedges can be shaped into artistic displays.
O A person who experienced malnutrition as a child is short in stature as an adult.
O Bears living in the arctic developed white fur and cold tolerance over many generations.
Certain breeds of dog have been bred for specific traits, such as poodles being bred for intelligence.
Answers
Answer:
O A person who experienced malnutrition as a child is short in stature as an adult.
Explanation:
Height is a quantitative trait, i.e., a phenotypic trait that depends on the combined action of many genes and the environment. Moreover, phenotypic plasticity can be defined as the ability of one genotype to produce different phenotypes in different environments. In consequence, quantitative traits are influenced by environmental factors and exhibit phenotypic plasticity. Quantitative traits are characterized to have a large variety of phenotypes and follow a normal distribution (a bell-shaped curve) when they are drawn.
What do you think the term gene expression means? How do you think the term relates to the total number of genes a human inherits from his or her parents?
Answers
Answer: Gene expression is how genes are expressed in an organism. This relates to the total number of genes from each parent because the number of genes from each parent determines how your genes are expressed physically.
Explanation:
It needs water vapor
in order to form
Answers
Clouds are created when water vapor, an invisible gas, turns into liquid water droplets. These water droplets form on tiny particles, like dust, that are floating in the air. ... That means some of the liquid water in the towel or bowl changed into an invisible gas called water vapor and drifted away into the atmosphere.
Maybe condensation??? but i feel like that would be too easy.
Without water vapor, there would be no clouds or rain or snow, since all of these require it in order to form and
Condensation is the process by which water vapor in the air is changed into liquid water. As condensation occurs and liquid water forms from the vapor, the water molecules become more organized and heat is released into the atmosphere as a result.
i don't wanna give a distinct answer because i could very possibly be wrong but i hope this helps in some way!

O D. An organism expresses different genes at different times in development, causing cells to be specialized

The cell types in a multicellular organism become different from one another because they synthesize and accumulate different sets of RNA and protein molecules. They generally do this without altering the sequence of their DNA.
Which of the following is a problem faced by the global economy? A. Decreasing cost of renewable resources O B. Increasing greenhouse gas emissions C. Increasing environmental awareness D. Decreasing human population
Answers
Answer:
B. Increasing greenhouse gas emissions
Explanation:
Increasing greenhouse gas emission leads to the global warming which is not only harmful for environment but also harmful for global economy.
Increasing emission of greenhouse gases rises the CO2 levels in the atmosphere which lowers the nutritional value of crops and highly affects the agricultural economy of the globally.
Greenhouse gases increases demand of space cooling which eventually decrease the demand for space heating, which is very costly.
Increasing emission of greenhouse gases has direct impact on climate change and climate change has indirect impact on several sectors which affect economy globally such as mining, manufacturing, trade, and finance.
Hence, the correct answer is "B. Increasing greenhouse gas emissions".

describe the effects that fire in the temperate grasslands biome has on grasses and on trees
Answers

When fire is suppressed, the vegetation eventually converts to scrub and dense forests. Often, the restoration or management of temperate grasslands requires the use of controlled burns to suppress the growth of trees and maintain the grasses. Burning causes new grass to grow, which brings back the grazing animals.
