Water ecosystems in europe have been damaged by too many fish being __________.a. fed
b. stocked
c. produced
d. harvested

Answers

Answer 1

Answer:

Answer:

The answer is d)harvested

Explanation:

Overfishing destabilize marine ecosystems. For example, many of the large fish, victims of overfishing, have almost disappeared from the oceans of Europe. Bluefin tunas have almost disappeared from the seas of Northern Europe. Sole is another fish that has almost disappeared in the North Atlantic. The most serious problems are due to trawls that, for example, are in the Irish Sea, where only shrimp and scallops are caught

Answer 2

Answer: The answer is D. Harvested
Hope this helps!

Answers

The statement is - True.

In the name Acer rubrum, the word rubrum is defining the species, while the acer is defining the genus.

Acer rubrum is actually the scientific name for the red maple tree, found mostly in the eastern half of the United States, being a native species to the North American continent.

The red maple is a tree in the family of Sapindaceae, and in the order of Sapindales.

It is considered as the most abundant native tree in the United States, and it is also one of the most used trees in the parks and homes in big portion of the United States.

Its true, according to the Binomial Classification Naming System, The second name in given is considered the species.

Which combination of alleles best describes a sex-linked trait? A. heterozygous alleles
B. homozygous alleles
C. alleles that are carried on X and Y chromosomes
D. alleles that are carried on somatic cells

Answers

B. homozygous alleles

Each human body is composed of genes, and these usually come in pairs that are slightly different from each other. The different versions of genes are called alleles. Alleles are responsible for determining physical or notable characteristics and traits a specific person has.

nuclear energy
tidal energy

Answers

Coal, petroleum, and oil are energy solutions that release pollution into the air.

Answer:

The correct answers are coal, petrolium and oil.

Explanation:

Coal is a fossil fuel that highly contributes to climatic change, polluting not only air but also water and the soil. By burning it, its gases contribute to increase the greenhouse effect and consequently producing global heat. This is affecting all forms of life that depend on these resources, including human beings. Thermal factories of coal for electricity production are the responsible source of CO, CO₂, SO₂ and NOₓ release. During the coal combustion process, several particles are released to air, polluting and being the cause of smog and acid rain. To produce only one tone of energy, coal emits 3.5 tones of CO₂, which is 1.5 more times than gas and 1.3 more times than petroleum CO₂ emission. In spite of its reduced use in the last years, coal is still the principal fuel used by thermal, refineries, chemical, and still work industries. It is also very important to mention that this production is the cause of the destruction of several species´ habitats and ecosystems that surround the mines.
Petroleum pollution is produced by its accidental or intended release in the environment, which produces adverse effects on all forms of life, directly or indirectly. This contamination involves all the operations related to hydrocarbon extraction and its transport, driving to a gradual environment deterioration, affecting soil, water, air, flora, and fauna. The areas occupied by the petroleum extraction installations affect the whole ground surface that ends in a completely degraded place. In superficial water sources, petroleum split and other wastes produce a decrease in oxygen, available solids, organic and inorganic substances. Underground water is affected by an increase in salinity by contamination. Ocean water is affected by conducts break in the bottom, or by ship splits. The air ais affected by gas emissions such as CO and CO₂.
Oil is also a huge contaminator and it generates a dangerous waste that is very harmful to the environment. Its elimination by incineration or split provokes huge pollution problems in the air, water, and ground. In water, it produces an impermeable film that impedes gas exchange and causes suffocation in the living forms that inhabit there. Only one oil liter contaminates one million liters of water. But if the oil is burned it generates nocive gases that are very toxic because of their content in plumb, chloride, phosphorus, sulfur, among others. Only 5 oil liters burned might contaminate 1 million cm³ of air.

Industrial and automobile emissions contribute to acid rain.

A chicken feed claims to produce more eggs. an experiment is to be conducted to determine whether the feed will lead to a higher egg production. it was determined the type of chickens impact egg production, but the amount of water a chicken drinks does not. how would blocking best be used? (1 point) a by blocking on chicken egg production b by blocking on chicken feed c by blocking on chicken water intake d by blocking on chicken type

Answers

Blocking would be best used 'by blocking on chicken type'. This means conducting separate trials for different types of chickens while testing the chicken feed because the type of chicken was determined to impact egg production.

In a scientific experiment where the aim is to conclude whether a certain chicken feed leads to higher egg production, blocking would be used to control the variables that might affect the result of the experiment. According to the information given, chicken's water intake is said to have negligible influence on egg production, however, the type of chicken does impact the production quantities.

Therefore, the ideal way to apply blocking to the experiment would be by differentiating the groups of chickens based on their type; this method is referred to as blocking on chicken type. The implication of this is, testing different chicken feeds on different types of chickens separately to ensure the accuracy of the experiment results by eliminating confounding factors.
