What is the term for a reaction in which a substance gains electrons?a.)respiration
b.)redox reaction
c.)reduction
d.)oxidation

Answers

Answer 1
Answer:

Answer:

The correct answer would be c.)reduction

Oxidation and reduction occur when transfer of electrons takes place from one element or atom to another.

The atom which receives or gains electron is said to be reduced while the atom which looses an electron is said to be oxidized.

For example, in cellular respiration oxygen gains electrons and H⁺ ions and is converted into water which is released as the byproduct of the process.

1/2 O₂ + 2 e⁻ + 2 H⁺ → 2H₂O

Answer 2
Answer: reduction 

"Reduction refers to ( chemical reactions in which a molecule gains electrons.)"

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

Answers

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

The answer is D. Harvested

The proper order, from smallest to largest, for the levels of organization is _______.a.
population, community, organism, biome, ecosystem, biosphere
b.
organism, community, population, ecosystem, biome, biosphere
c.
biosphere, biome, ecosystem, community, population, organism
d.
organism, population, community, ecosystem, biome, biosphere

Answers

The proper order, from smallest to largest, for the levels of organization is d.  organism, population, community, ecosystem, biome, biosphere.

  • The level of organization begins with an organism an organism is a viable individual who performs various life processes like respiration, reproduction, excretion, and others to sustain its life.
  • A population is a group of more than one organism of the same kind.
  • A community is a group of two or more population of distinct organisms.
  • Ecosystem is a biological community where living beings interact with their surrounding environment.
  • Biome is a place which include one or more ecosystems like tropical forests, tundra, savannas, grasslands, and others.
  • Biosphere includes one or more spheres where living beings survive like hydrosphere, atmosphere, and lithosphere.

Hence, the proper order, from smallest to largest, for the levels of organization is d.  organism, population, community, ecosystem, biome, biosphere.

Final answer:

The correct order from smallest to largest is organism, population, community, ecosystem, biome, and biosphere. This hierarchy is essential for understanding ecological relationships and how biological organization is structured.

Explanation:

The levels of biological organization form a hierarchy in which each level builds upon the one below it. At the very basic level, we have the organism, which is an individual living entity. A group of organisms of the same species that live in the same area is called a population. When multiple populations of different species interact in an area, they form a community. The community, along with the nonliving components of the environment, constitutes an ecosystem. A biome is a larger area that includes multiple ecosystems with similar climates and vegetation. Finally, the biosphere encompasses all the biomes and represents the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, hydrosphere, and atmosphere.

Given the provided hierarchy, the correct sequence from smallest to largest is:

  1. Organism
  2. Population
  3. Community
  4. Ecosystem
  5. Biome
  6. Biosphere

Therefore, the correct answer to the student's question is option d: organism, population, community, ecosystem, biome, biosphere.

Dr. Slotsky is a well-liked professor. Last term, no one received less than a B in any of his courses. Dr. Slotsky may be suffering from _________ perceptual error.

Answers

The question is incomplete as it does not have the option which are:

1. Halo

2. Leniency

3. Central tendency

4. Recency

Answer:

Leniency

Explanation:

A perceptual error is a phenomenon which occurs when the person holds some preconceived ideas about some other person on the basis of which the person is not able to make accurate perceptions about the person.

In the given question since the Dr. has not given less than B grade, this could be the result of the Halo type of perceptual error in which the person assumes that one parameter can be responsible for all other parameters and the person make incorrect errors like he could have considered attendance as a parameter ad on the basis of that he could have become more lenient towards the student with full attendance.

Thus, Leniency is the correct answer.
